    The use of simulators for training FESS may in the future offer substantial advantages like increased exposure to difficult scenarios, reduced learning curves, and reduced costs. Training simulators may range from very simple, involving only visual simulation, to more complex, involving haptic

    Having one hand occupied with the endoscope is the major disadvantage for the surgeon when it comes to functional endoscopic sinus surgery (FESS). Only the other hand is free to use the surgical instruments. Tiredness or frequent instrument changes can thus lead to shaky endoscopic images. We collected the pose data (position and orientation) of the rigid 0° endoscope and all the instruments used in 16 FESS procedures with manual endoscope guidance as well as robot-assisted endoscope guidance. In combination with the DICOM CT data, we tracked the endoscope poses and workspaces using self-developed tracking markers. All surgeries were performed once with the robot and once with the surgeon holding the endoscope. Looking at the durations required, we observed a decrease in the operating time because one surgeon doing all the procedures and so a learning curve occurred what we expected. The visual inspection of the specimens showed no damages to any of the structures outside the paranasal sinuses. Robot-assisted endoscope guidance in sinus surgery is possible. Further CT data, however, are desirable for the surgical analysis of a tracker-based navigation within the anatomic borders. Our marker-based tracking of the endoscope as well as the instruments makes an automated endoscope guidance feasible. On the subjective side, we see that RASS brings a relief for the surgeon.

    Coronal CT of the paranasal sinuses and the ostiomeatal complex (OMC) was performed before and 12 months after bilateral functional endoscopic sinus surgery (FESS) in 30 patients with sinusitis and 12 patients with nasal polyposis. The extent of sinus mucosal thickening was graded, and the patency of the OMC was evaluated. After FESS, the percentage of open OMCs had increased from 42% to 83% in the sinusitis group, and from 8% to 45% in the polyposis group. There was only a small improvement in mucosal score in sinuses with opened OMC, so that the overall extent of sinus opacification before and after FESS was almost the same. Despite this, 91% of the patients reported clinical relief of symptoms. Preoperative coronal CT of the paranasal sinuses serves as an anatomical map for the surgeon, but there is no benefit of routine postoperative CT. (orig.)

    Full Text Available A 41-year-old female with a history of uterine cancer and Celiac and Raynaud’s Disease presented to our institution with frequent migraines and nasal congestion. She underwent functional endoscopic sinus surgery (FESS and experienced acute unilateral vision loss postoperatively. Rapid recognition of the etiology and effective treatment are paramount given the permanent and irreversible vision loss that can result. Arterial vasospasm following FESS is rare. Patients with autoimmune diseases have perhaps an increased risk for vasospasm secondary to an increased vasoreactive profile. We present the first documented case of nitroglycerin sublingual therapy to successfully treat ophthalmic artery vasospasm following FESS. Nitroglycerin sublingual therapy is a promising treatment for ophthalmic vasospasm secondary to its ability to cross the blood-ocular barrier, its rapid onset of action, and its ability to promote relaxation of vascular smooth muscle.

    Nasal polyposis is often encountered in rhinology practice. Those who fail conservative management, a definitive surgery is essential to achieve sufficient ventilation and drainage of the affected sinuses by using either microdebrider or conventional instruments for functional endoscopic sinus surgery (FESS). A prospective study was conducted on 40 cases of nasal polypi in a tertiary care hospital. 20 cases were operated by conventional endoscopic instruments and 20 using the microdebrider. The study aimed at comparing the intra operative (blood loss, duration of surgery) and post operative results (crusting, scarring, discharge, symptoms, recurrence) between the two groups using Lund-Mackay scoring system and the data was statistically analysed. There was no statistically significant difference in surgical outcome for patients when either conventional endoscopic instruments or microdebrider was used. However, there was a significant symptomatic improvement in cases undergoing microdebrider FESS. Microdebrider assisted polypectomy is precise, relatively bloodless surgery though the precision depends on the surgeon's anatomical knowledge and operative skills. Study substantiates that these instruments are helpful but not a prerequisite for successful outcomes in FESS. The study re-emphasises the utility of the microdebrider to young learning FESS surgeons.

    Pediatric functional endoscopic sinus surgery (FESS) is now commonly performed for chronic rhinosinusitis therapy. The surgery is necessary when symptoms of sinusitis persist after maximal medical treatment. Apart from anatomic and technical issues the main difference between adult and pediatric FESS is related to postoperative care. In earlier reports a second-look endoscopy in general anaesthesia was recommended to inspect, debride and clean the operative site in young patients. The aim of the study was to estimate the results of FESS surgery in children and to propose a relevant way for postoperative care. FESS surgery was performed in 64 children (mean age 13, 2 years) and postoperative follow-up was available in 47 children (33 girls, 14 boys). The protocol for postoperative follow-up based on our notes and literature is suggested. All patients after surgery were instructed to use saline solution or Ringer solution for nose cleaning. Seven days after surgery nasal steroids were implemented. Second look endoscopy with wound debridement in general anaesthesis was necessary in 8 children (13%) after major procedures, where a lot of crust and blood clots in postoperative site were noted. It is suggested that formation of synechiae and granulation tissue in the early postoperative period is one of the adverse prognostic factors in FESS outcome. In spite of not aggresive approach to follow-up, wound inspection and postoperative site cleaning the synechiae were found in 2 (3%) patients only. 30 children (64%) were symptoms--free after surgery. Functional endoscopic sinus surgery (FESS) is efficient treatment for chronic rhinosinusitis in children. Aggresive post operative site debridement is rarely necessary. Postoperative general anaesthesia "second-look procedure" is indispensable in a few patients only but it needs an individual approach for each child.

    The technique of functional endoscopic sinus surgery (FESS) has been widely accepted and applied to inflammatory diseases of the paranasal sinuses with internationally reported results of this technique having been very good. Our objective was to find out outcome after FESS at our centre. Two hundred patients who had undergone FESS during a two year period with an average follow-up period of eleven months were evaluated subjectively regarding the outcome of their endoscopic sinus surgery. An overall subjective improvement of about 94% was documented, with improvement in specific symptoms such as headache, nasal congestion, change in sense of smell, nasal discharge and recurrent infections ranging from 52% to 97%. Our center reports a subjective improvement of symptoms following FESS compatible with results attained internationally. (author)

    Functional endoscopic sinus surgery (FESS) is nowadays the "gold standard" for frontal sinus pathologies, but management of acute situations and the aproach and/or the extent of the surgery perfomed in the frontal recess remains controversial nowadays. We report our experience in 4 patients with orbital celulitis due to frontal sinusitis who underwent combined external surgery (mini-trephination) and endoscopic sinus surgery. All patients managed sinus patency without any complications. We found this combined sinusotomy as an easy, effective and reproductible technique in order to resolve the difficult surgical management of complicated frontal sinusitis.

    Chronic rhinosinusitis (CRS) is a common disease with significant effects on the quality of life. Infection was previously a common cause of rhino sinusitis, while nowadays its main cause is inflammation. Non-polyposis CRS patients who were resistant to medical treatment and underwent endoscopic sinus surgery in Ghaem and Imam Reza hospitals were studied from December 2008 to November 2009. There were 11 males and four females ranging in age from 14 to 57 years with the average age of 32.2. First, samples were taken from the ethmoid sinus and the ipsilateral middle turbinate. Then, histopathologic research on grade of inflammation, mucosal thickness, inflammatory cell count, metaplasia type, and hypersecretion was performed. Fifteen patients were studied. There were positive statistical correlations between inflammation grade, eosinophil counts and plasma cell counts in ethmoid and turbinate; but such a correlation was not found in lymphocyte and neutrophil in two sites. The prominent inflammatory cell in both areas was the same for 11 patients; whereas in other four cases, it was insignificantly different. Positive statistical correlation between the inflammation grades in two sites shows the coexistence of rhinitis and sinusitis; therefore, this proves the correct combination usage of rhinosinusitis. Prominent cells of the samples which were obtained from two places were similar for most patients, so this similarity is a sign of inflammatory process presence in both places. The prominent cells were mostly lymphocytes.There were more lymphocytes than eosinophils in non-allergic patients.

    Intracranial air is a common finding after many neurosurgical procedures and trauma to the head. In patients requiring transport via air to reach a destination there is risk of expansion of the intracranial air and development of neurological complications. Though relatively uncommon after functional endoscopic sinus surgery (FESS), pneumocephalus may be encountered. We describe one of our patients in whom intracranial air was introduced during FESS. Following the procedure she required commercial air transportation from our center to her home. A 45-min commercial flight to the destination was safely completed without the patient experiencing any neurological sequellae. This case highlights the controversy surrounding air travel with pneumocephalus and provides an example of safe commercial air travel after diagnosis of post-FESS pneumocephalus.

    To analyze the efficacy of FESS in patients with recurrent nasal polyposis in terms of relief of nasal obstruction, improvement in sense of smell and to assess recurrence of disease. Study Design: Descriptive case series. Materials and Method: All patients who underwent FESS (Functional endoscopic sinus surgery) for recurrent nasal polyposis from June 2008 to June 2010 with an average follow up of 06 month were included. Clinical symptoms including nasal obstruction and olfactory disturbance were evaluated using VAS system pre and postoperatively. Preoperatively computed tomography scan was done in all cases to assess extent of disease and surgical anatomy. Results: Following FESS 96% of total patients demonstrated statistically significant improvement in relieving nasal obstruction after 6 months follow up, however improvement in sense of smell was seen in 44% of patients. Recurrence was seen in only 3 (6%) cases at 3rd and 6th month follow up. Conclusion: Functional endoscopy sinus surgery of recurrent nasal polyposis is an effective method of surgery with significant improvement of symptom of nasal obstruction and olfaction with minimal recurrence at 6 month in our centre. Our results were compatible with results attained internationally. (author)

    The aim of this clinical investigation was to evaluate the clinical and radiologic outcomes of a single-step surgical procedure that includes functional endoscopic sinus surgery (FESS) and maxillary sinus elevation by the lateral window approach in patients with reversible contraindications to sinus elevation. Thirty-eight patients with insufficient bone height in the posterior maxilla caused by pneumatization of the sinus and with reversible ear-nose-throat (ENT) contraindications to sinus elevation were recruited for this investigation between January 2010 and January 2012. All patients were treated in a single session under general anesthesia for a total of 69 consecutive sinus augmentations. FESS was performed by an ENT specialist, and an oral surgeon carried out sinus elevation through the lateral window approach. Particulate xenograft was used beneath the sinus membrane. Intraoperative and postoperative complications (eg, membrane tears, rhinosinusitis, graft infection or loss) were reported. Nasal endoscopies were performed at 7, 14, and 30 days and 3 months after treatment. After a healing period of 6 months, 137 implants were inserted. Computed tomography scans were performed after 6 months and 1 year. Intraoperative membrane perforation occurred in only one case. No implant failures were recorded during the follow-up period. Radiologic and clinical findings showed the resolution of ENT disease and good bone graft integration after 1 year. A relapse of mucosal thickening observed in some patients did not influence the graft healing. Preliminary rhinosinusal evaluation by an ENT specialist and computed tomography of the ostiomeatal complex are necessary in patients needing maxillary sinus elevation. A single-step approach to FESS and sinus elevation is a predictable technique to manage patients with ENT reversible contraindications to sinus elevation.

    The olfactory loss in patients with chronic rhinosinusitis has been measured by different methods. However, the results have been variable and it is not clear whether functional endoscopic sinus surgery (FESS) significantly improves olfactory function. This study was performed to evaluate the influences of FESS on olfactory function in patients with chronic rhinosinusitis using three different types of olfactory tests. Seventy patients with chronic rhinosinusitis were administered the University of Pennsylvania Smell Identification Test (UPSIT), a single staircase phenyl ethyl alcohol odor detection threshold test (STT), and a short-term odor memory/discrimination test a day before and 6 months after FESS. A questionnaire inquiring about the patients' self-perception of olfactory function was administered also. Independent ratings of the severity of chronic rhinosinusitis before FESS were established from CT scans. Fifty-two (74.3%) of the patients reported that their olfactory function was impaired before surgery, and 68.6% of the patients reported impaired olfactory function after surgery, a difference that was not significant. No meaningful changes in any of the olfactory test scores were noted 6 or more months after FESS. Preoperatively, small correlations between CT scores and the symptom scores (r = 0.278; p = 0.024), threshold scores (r = -0.27; p = 0.031), and UPSIT scores (r = -0.36; p = 0.003) were observed. In patients with severe rhinosinusitis, FESS had little impact on the ability to smell, regardless of the method for assessing smell function. Subtle associations between olfactory function and the severity of chronic rhinosinusitis determined by CT were observed, however, preoperatively. The olfactory test measures were correlated with one another both pre- and postoperatively.

    Functional endoscopic sinus surgery (FESS) is an effective treatment for chronic rhinosinusitis (CRS). Postoperative management strategies after FESS often vary from surgeon to surgeon. Recent data suggests that nasal saline irrigation following FESS is almost universally recommended; however, patient adherence has not been formally evaluated. The purpose of this study is to evaluate postoperative nasal irrigation practices and its effects on short-term outcomes in post-FESS patients. Eighty-two patients were followed prospectively following FESS at a tertiary-academic medical institution for 3 postoperative visits. Patients were surveyed on their irrigation practices (start date, frequency, and volume per irrigation per side), and adherence to prescribed antibiotic and steroid regimens. At each visit, 22-item Sino-Nasal Outcome Test (SNOT-22) questionnaires and endoscopic examinations were evaluated by the Lund-Kennedy Endoscopy Score (LKES). Factors evaluated include: patient demographics (age, sex, ethnicity), preoperative Lund-Mackay and SNOT-22 scores, comorbidities, extent of procedure, and use of nasal packing and/or spacers. Adherence to irrigation instructions was 82.9%. Factors significantly associated with compliance with irrigation instructions included younger age (p = 0.0022), prior irrigation (p < 0.0001), revision surgery (p = 0.0014), and non-native English language speaking (p = 0.0095). Patients were more likely to irrigate with larger volumes if they were younger (p = 0.0284), had prior irrigation (p < 0.0001), or had revision surgery (p = 0.0056). Multiple factors are associated with patient compliance with nasal saline irrigation after FESS. Ethnic and cultural considerations, such as language barriers, should also be considered to improve outcomes. Identification of patients who may be noncompliant could potentially benefit from increased preoperative counseling to improve adherence rates. © 2017 ARS-AAOA, LLC.

    2013-06-01

    Functional endoscopic sinus surgery (FESS) has been used as the standard of treatment for sinonasal disease in which medical therapy fails to ameliorate the disease. Intraoperative hemostasis is a crucial factor in FESS. Currently, ideal techniques for creating intraoperative hemostasis have yet to be clarified and standardized. We sought to better understand what variables can affect intraoperative blood loss and therefore improve surgical field outcomes. A literature search was conducted using PubMed, OVID, MD Consult, and Micromedex with keywords including: FESS, intraoperative blood loss, hemorrhage, and vasoconstriction. The articles were then evaluated with regard to blood loss, surgical grade, and operative time. Eleven articles were cross-referenced to determine the most statistically significant techniques in 3 main categories: general anesthetics, preoperative steroids, and use of epinephrine. Analysis of the articles indicate that total intravenous anesthesia (TIVA) is statistically more beneficial than balanced anesthesia (BA), providing an average difference in blood loss of 75.3057 mL; the use of preoperative steroids is statistically more beneficial than placebo, with an improved difference in blood loss of 28 mL; and a trend toward hemostasis with the use of local anesthetics at a concentration of 1:200,000. Meta-analysis of 1148 patients concludes that hemostasis during FESS is best conducted using TIVA, preoperative steroids, and topical local anesthetic at a 1:200,000 concentration. © 2012 ARS-AAOA, LLC.

    Full Text Available Background: Kartagener syndrome (KS is a rare congenital disease characterised by a clinical triad of symptoms: situs inversus, chronic rhinosinusitis, and bronchiectasis. Although congenital ciliary defect is recognised as the main cause of this syndrome, it remains difficult to treat the associated airway infection. Case Report: A 17-year-old female patient presented with repeated refractory airway infection. She also had bronchiectasis and situs inversus. Electron microscopic evaluation of her nasal mucosa revealed ciliary defect and confirmed the diagnosis of KS. She underwent functional endoscopic sinus surgery (FESS followed by long-term postoperative debridement of the sinonasal cavity. This treatment reduced chronic rhinosinusitis and protected against subsequent airway infection in a 7-year follow-up. Conclusion: FESS is effective for relieving both chronic rhinosinusitis and lung infection of KS in the long term.

    Background and purpose: Today, functional endoscopic sinus surgery (FESS) is performed in most of the patients with sinonasal inflammatory disease. The postoperative imaging findings of FESS in multidetector computed tomography (MDCT) considerably differ from those of historic Caldwell-Luc (CL) maxillary sinus surgery which is an uncommon procedure today. Thus, the postoperative CL imaging findings may lead to diagnostic confusion and misinterpretation. Therefore, this study explicitly presents the MDCT findings of post-CL patients which have not been described previously. Methods: Twenty-eight patients with clinically suspected sinusitis and documented history of CL-procedure underwent 16 row MDCT (MDCT Mx8000 IDT Philips) with multiplanar reconstructions of the paranasal sinuses in the axial plane. The following parameters were used: 140 kV, 50 mAs; 16 mm x 0.75 mm detector collimation; 1 mm reconstructed slice thickness; 0.5 mm increment. The studies were reconstructed with a bone algorithm (W3000/L600; 1 mm slice thickness) in axial plane and coronal plane (3 mm slice thickness). The images were retrospectively evaluated for the presence of normal surgery-related and pathological findings. Results: Surgery-related imaging characteristics presented as follows: an anterior and a medial bony wall defect and sclerosis and sinus wall thickening were observed in all 28/28 cases (100%). Collaps of the sinus cavity was seen in 26/28 cases (92.9%). Furthermore, inflammatory disease of the operated sinus(es) was found in 23/28 cases (82.1%): 14/28 patients (50%) had inflammatory mucosal thickening of the operated sinus(es) as well as of other sinonasal cavities and 9/28 patients (32.1%) had inflammatory mucosal thickening limited to the operated sinus(es). A postoperative mucocele was depicted in 3/28 cases (10.7%). 2/28 patients (7.1%) showed neither maxillary nor other mucosal swelling. Conclusion: MDCT with multiplanar reconstructions is a precise method to evaluate

    Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3–4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

    Chronic rhinosinusitis with nasal polyps (CRSwNP) is rare in children and has a major impact on Quality of Life (QoL). Functional endoscopic sinus surgery (FESS) has proven to be an effective treatment, but it is still unclear what long-term outcomes are in children with CRSwNP. The objective of this study was to assess long-term results of FESS in children with CRSwNP. We performed a combined prospective and retrospective study. A QoL questionnaire was send to all children with CRSwNP who received FESS between the year 2000-2010. Almost half of these children also filled in this questionnaire preoperatively. Forty-four Children underwent FESS. From 18 patients, we also prospectively collected preoperative QoL questionnaires. The mean follow-up period was 4.0 years (+- 2.9). The mean age at surgery was 13 years (+-2.9). Of these children, 9 had CF and 10 children asthma. R-SOM scores showed a significant improvement both in general symptoms as well as several different domains when comparing pre- and postoperative questionnaires. Only 5 of 44 patients needed a subsequent intervention. In children with CF this was 3 of 9. This study demonstrates that long-term results of FESS in children with CRSwNP are good. QoL has improved significantly, especially in nasal symptoms, showing that FESS is a good treatment in children with CRSwNP. Furthermore, even children with CF show good results.

    The use of image-guided navigation systems in the training of FESS is discussed controversy. Many experienced sinus surgeons report a better spatial orientation and an improved situational awareness intraoperatively. But many fear that the navigation system could be a disadvantage in the surgical training because of a higher mental demand and a possible loss of surgical skills. This clinical field study investigates mental and physical demands during transnasal surgery with and without the aid of a navigation system at an early stage in FESS training. Thirty-two endonasal sinus surgeries done by eight different trainee surgeons were included. After randomization, one side of each patient was operated by use of a navigation system, the other side without. During the whole surgery, the surgeons were connected to a biofeedback device measuring the heart rate, the heart rate variability, the respiratory frequency and the masticator EMG. Stress situations could be identified by an increase of the heart rate frequency and a decrease of the heart rate variability. The mental workload during a FESS procedure is high compared to the baseline before and after surgery. The mental workload level when using the navigation did not significantly differ from the side without using the navigation. Residents with more than 30 FESS procedures already done, showed a slightly decreased mental workload when using the navigation. An additional workload shift toward the navigation system could not be observed in any surgeon. Remarkable other stressors could be identified during this study: the behavior of the supervisor or the use of the 45° endoscope, other colleagues or students entering the theatre, poor vision due to bleeding and the preoperative waiting when measuring the baseline. The mental load of young surgeons in FESS surgery is tremendous. The application of a navigation system did not cause a higher mental workload or distress. The device showed a positive effort to engage

    Nasal packings can aid in control of postoperative bleeding and healing following functional endoscopic sinus surgery (FESS), but traditional non-resorbable stents have several inherent drawbacks. We performed a randomized, controlled, multicenter clinical trial to assess efficacy of resorbable nasal packing in patients undergoing FESS for chronic rhinosinusitis. A total of 66 patients for 88 nasal cavities were randomized to receive either hyaluronan resorbable packing (MeroGel) or standard non-resorbable nasal dressing after FESS. All underwent preoperative rhinoscopy, CT of sinuses, and, after surgery, were reassessed by rhinoscopy at 2, 4, and 12 weeks in blinded fashion. A total of 44 nasal cavities (MeroGel-group) received resorbable packing, whereas the remaining 44 were packed with non-resorbable nasal dressing. At follow-up endoscopic visit, the presence of nasal synechia was evaluated as primary outcome. Moreover, the tolerability and surgical handling properties of MeroGel and its comfort were assessed by surgeons and patients. Preoperative severity of rhinosinusitis was similar in both groups. No significant adverse events were observed in all patients. Follow-up endoscopy showed a lower proportion of nasal adhesions in MeroGel-group at both 4 (P = 0.041) and 12 weeks (P appearance of nasal mucosa of nasal cavities after FESS was observed in the MeroGel-group. Tolerability and surgical handling properties of MeroGel were positively rated by clinicians and the overall patient judged comfort of MeroGel was favorable. In conclusion, MeroGel can be considered a valid alternative to standard non-resorbable nasal dressings. It is safe, well-accepted, well-tolerated, and has significant advantage of being resorbable. Moreover, it may favor improved healing in patients undergoing FESS and reduce formation of adhesions.

    Endeavor to intraoperative macroscopic evaluation of changes in children with CRSs. Analysis of the type and incidence of pathological changes observed macroscopically during FESS was undertaken as well as an parallel attempt to correlate the level of inflammation markers with severity of disease. Retrospective analysis of case records of 153 patients of the Department of Pediatric Otolaryngology, Medical University of Warsaw, hospitalized between 2010 and 2013. During that time 106 patients with a diagnosis of chronic maxillary sinusitis required surgical intervention. 102 children (avg-aged 11.5 years) were qualified to functional endoscopic surgery. The youngest patient was 3 years old and the oldest 18. 26 patients presented the polypoid lesions of sinuses or nasals. At 19 confirmed the coexistence of sinus polyps with nasal polyps. 76 patients had oedematous-inflammatory lesions and 26 polypoid. Among the group of listed above 26 children, 19 had either sinuses or nasal polyps. 15% children with polyps were diagnosed with cystic fibrosis and 8.0% with asthma. A common deviation in the results of morphology in children with CRSs is higher level of monocytes. Inflammation markers within the population of FESS qualified children were low. (1) Oedematous-inflammatory lesions are frequently intraoperatively identified. (2) The CRSs without polyps is the common type of chronic sinusitis in children. (3) Nasal polyps often coexist with sinus polyps. (4) If nasal polyps are found in pediatric population then diagnosis of CF, allergy and GERD should be considered. (5) Markers of inflammation in CRSs are low. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Intraoperative bleeding causing poor visibility of surgical field is of major concern during functional endoscopic sinus surgery (FESS) and impaired visibility may result in many complications. The study aimed to compare surgical conditions for FESS during controlled hypotension provided by esmolol or nitroglycerine (NTG) under general anaesthesia. 52 adult patients of both sexes requiring FESS under general anaesthesia were randomly divided to receive either esmolol (group ESM, n = 26) or NTG (group NTG, n = 26) to provide controlled hypotension. Surgical condition was assessed by surgeon using average category scale (ACS) of 0-5, a value of 2-3 being ideal. In both groups mean arterial blood pressure (MABP) was gradually reduced till ACS for assessment of surgical condition (ACS) of 2-3 or lowest targeted MABP (60 mm of Hg) was achieved. Both the drugs produced desired hypotension and improved surgical condition by reducing operative field bleeding but ideal operative conditions were achieved at mild hypotension (MABP 75-70) in ESM group while same conditions were achieved at MABP of 69-65 mm of Hg in NTG group. Mean heart rate was significantly higher in NTG group as compared to ESM group. Blood loss was significantly less in ESM group. Both NTG and esmolol can be used safely to provide controlled hypotension during FESS. Both the drugs improved visibility of surgical field by reducing capillary bleeding. But esmolol offered better operative conditions with only minimal reduction in MABP. No reflex tachycardia and less intraoperative haemorrhage were additional advantages of esmolol.

    The reference standard for preoperative imaging in functional endoscopic sinus surgery (FESS) is multiplanar high-resolution computed tomography (HRCT). Surgeons require a precise preoperative anatomical road map, and hence it is essential for radiologists to be familiar with the normal three-dimensional sinonasal anatomy and the normal variants encountered in this region. Sagittal imaging has recently emerged as an important tool to visualize additional details in this critical anatomical region. Radiologists also need to report these examinations with special focus on the surgeon's expectations. Constant communication between the radiologist and the surgeon helps to resolve specific issues and improve the overall quality of reports. This results in better preoperative patient counselling and in predicting postoperative improvement in clinical status. This review provides a basic structured format for reporting pre-FESS CT, which can be tailored to meet individual requirements. The CT reporting format follows the order in which the sinonasal structures are approached during surgery.

    To properly understand the basic theory and the clinical application of the functional endoscopic sinus surgery and the traditional technique. The indications, extend of excision, operative approach, complication and curative effect of 1,740 cases(3,140 sides) done in the China-Japan Friendship Hospital and Jining Jiaotong Hospital were analysed. Among them, 522 cases(1,032 sides, 30%) received the traditional technique for sinusitis; 1,218 cases(2,108 sides, 70%) received functional endoscopic sinus surgery. Three hundred and ninety-eight cases of traditional ethmoid sinus operation and 352 of functional sinus surgeries were followed-up and their cure rates were 80% and 93% respectively. Both groups had no serious complications. The main indications of functional sinus surgery are infectious nasal sinus diseases or meatus nasi lesion that may interfere with the drainage. Such kinds of diseases have high morbidity than the diffused polyposis and deserves attention. Traditional operations for frontal and maxillary sinusitis should be controlled appropriately, but the traditional sphenoid sinus operation is still an effective treatment for the diffused polyposis.

    The aim of this study is to determine the range of S-100β levels during functional endoscopic sinus surgery (FESS) when the mean arterial pressure (MAP) was controlled within 60-70 mmHg. After anesthesia induction with propofol and remifentanil, the patient was positioned in the reverse Trendelenburg position and MAP was controlled within 60-70 mmHg during surgery. For the S-100β assay, blood was taken from a radial arterial catheter before (baseline) and at 20 (T 20 ) and 60 (T 60 ) min after setting the reverse Trendelenburg position and controlled hypotension, and at 60 (T post60 ) min after the end of the operation. In total, 34 patients completed the study. Baseline S-100β was 0.00837 ± 0.00785 ng/mL. The levels at T 20 and T 60 were 0.02057 ± 0.01739 and 0.01987 ± 0.01145 ng/mL, respectively. The level of T post60 was 0.05436 ± 0.02318 ng/mL. The level at T 20 increased significantly versus the baseline level (P hypotension (MAP >60 mmHg) was provided. Thus, moderate hypotension would be seemed to be a safe and effective anesthetic technique for FESS without risk for cerebral ischemia.

    Controlled hypotension with balanced anaesthesia minimises blood loss. This study was done to evaluate the effectiveness of intravenous clonidine as a single bolus dose to establish controlled hypotension during functional endoscopic sinus surgery (FESS). This randomised, double-blind, placebo-controlled study was done in a tertiary hospital in India. Sixty American Society of Anesthesiologists physical status I and II patients (18-65 years) undergoing FESS were randomly allocated to one of the two groups. Placebo group (group A, n = 30) received sterile water whereas the clonidine group (group B, n = 30) received 3μg/kg of clonidine intravenously, 30 min prior to induction of anaesthesia. The primary outcome was to achieve a target mean arterial blood pressure (MAP) of 55-65 mmHg intraoperatively. The secondary outcomes measured were requirement of additional fentanyl and metoprolol, intra-operative blood loss, surgeon's opinion on the surgical field, pain, sedation score and complications requiring treatment. Target MAP was easily achieved in clonidine group as against the placebo group ( P hypotensive drugs and good analgesia ( P = 0.01) were seen in clonidine group. The complication rates were similar in both the groups. Clonidine is effective in achieving controlled hypotension in patients undergoing FESS. It reduces intra-operative blood loss, requirement of additional hypotensive drugs, improves the surgical field and offers good analgesia without significant side effects.

    Controlled induced hypotension guarantees less blood loss and better visibility of the surgical site. The impact of hypotension on post-operative cognitive functions is still being discussed. The objective of this study was to evaluate the effects of controlled induced hypotension on the cognitive functions of patients undergoing functional endoscopic sinus surgery (FESS). We allocated 47 patients with a good grade of preoperative cognitive functions evaluated with the Mini-Mental State Examination to 3 groups (1 - mild hypotension, 2 - intermediate hypotension, 3 - severe hypotension) according to the degree of mean intraoperative arterial pressure compared with preoperative blood pressure. Cognitive functions were evaluated preoperatively, 6 h, and 30 h postoperatively with standardized tests: the Stroop Test, Trail Making Test (TMT), and Verbal Fluency Test (VFT). A decrease in the test results and increase in the number of mistakes made were considered an impairment of cognitive functions. A total of 47 patients (group 1 - mild hypotension - 15, group 2 - intermediate hypotension - 19, group 3 - severe hypotension - 13) were included in the study. A significant decrease was observed in all the 3 groups after Stroop A test 6h postoperatively but it improved 30h postoperatively, without differences between the groups. Neither a significant decrease in the test results nor an increase in the number of mistakes was noted for Stroop B tests, TMT A&B tests and VFT. The degree of controlled intraoperative hypotension during FESS did not influence the results of psychometric tests.

    The aim of our study is to systematically review the existing evidence on the role of corticosteroids in patients undergoing functional endoscopic sinus surgery (FESS). Systematic search of MEDLINE (1950- 2014), EMBASE (1980-2014), metaRegister, Cochrane Library and ISI conference proceedings was carried out. Eighteen randomised controlled trials with 1309 patients were included. Use of local and/or systemic corticosteroids with FESS was reported in four categories; operative, anaesthesia related, post-operative outcomes and risk of recurrence. Meta-analysis for operative outcomes demonstrated that, mean operative time (MD -10.70 minutes; 95% CI -15.86, -5.55; P <0.0001) and mean estimated blood loss (MD -28.32 mls; 95% CI -40.93, -15.72; P <0.0001) was significantly lower; and surgical field quality (MD -0.81; 95% CI -1.32, -0.30; P = 0.002) was significantly better in corticosteroid group. Meta-analysis showed that post-operative endoscopic scores (SMD -0.39; 95% CI -0.60, -0.17; P = 0.0004) were significantly better in corticosteroid group compared to no corticosteroid group. There was no increase in risk of sinusitis (RR 0.64; 95% CI 0.32, 1.30; P = 0.22) between use of corticosteroids and no corticosteroids; There was no significant difference in recurrence risk of chronic rhinosinusitis (CRS) in mixed population studies (RR 0.77; 95% CI 0.35, 1.70; P = 0.52) between the two groups but analysis of studies reporting on chronic rhinosinusitis with nasal polyps (CRSwNP) (RR 0.64;95% CI 0.45,0.91;P=0.01) showed significant difference in favour of the corticosteroid group. Pre-operative use of local and/or systemic corticosteroids in FESS, results in significantly reduced blood loss, shorter operative time and improved surgical field quality. Studies are limited on the intra-operative use of corticosteroids to reduce postoperative pain. Postoperative corticosteroids improve postoperative endoscopic scores in CRS and recurrence rates in cases of CRSwNP.

    Assess paranasal sinus distribution of topical solutions following endoscopic sinus surgery (ESS) using various delivery devices. Experimental prospective study. Ten cadaver sinus systems were irrigated with Gastroview before surgery, after ESS, and after medial maxillectomy. Delivery was via pressurized spray (NasaMist), neti pot (NasaFlo), and squeeze bottle (Sinus Rinse). Scans were performed before and after each delivery with a portable CT machine (Xoran xCAT), and blinded assessments were made for distribution to individual sinuses. Total sinus distribution was greater post-ESS (P squeeze bottle > pressurized spray (P spray solutions in un-operated sinuses provide little more than nasal cavity distribution. Use of squeeze bottle/neti pot post-ESS offers a greatly enhanced ability to deliver solutions to the paranasal sinuses.

    Full Text Available BACKGROUND This study is undertaken to compare the hemodynamic effects and reduction in the doses of volatile anaesthetics and muscle relaxants using two different doses of dexmedetomidine infusion during maintenance of anaesthesia in spine, functional endoscopic sinus surgery and middle ear surgeries. METHODS Sixty patients are randomly divided into 2 groups of 30 each. After shifting to the operation theatre baseline vitals were recorded. Anesthesia induced with thiopentone sodium and intubation done with the help of succinylcholine and maintained with oxygen, nitrous oxide and isoflurane. After 1 min of intubation, maintenance infusion of dexmedetomidine (0.4 mcg/kg/hr and 0.7 mcg/kg/hr for patients allotted in 2 separate groups was started and stopped 15 min before end of surgery. Hemodynamic parameters and any reduction in the doses of volatile anaesthetics and muscle relaxants was noted. RESULTS Dexmedetomidine infusion (0.4 mcg/kg/hr and 0.7 mcg/kg/hr in both groups reduced the requirements of muscle relaxants and volatile anaesthetics. Hemodynamic stability was better in the group receiving 0.4 mcg/kg/hr. Patients receiving 0.7 mcg/kg/hr had higher incidence of hypotension, bradycardia and delayed emergence from anaesthesia. CONCLUSION Dexmedetomidine infusion at 0.4 mcg/kg/hr during maintenance of anaesthesia in spine surgery, FESS and middle ear surgery would be good option to reduce the requirements of volatile anaesthetics, muscle relaxants and for better hemodynamic stability. OBJECTIVE OF STUDY: Primary Objective To compare and evaluate the hemodynamic effects and reduction in requirements of volatile anaesthetics and muscle relaxants with two different doses of dexmedetomidine infusion during maintenance of general anaesthesia in patients undergoing spine, FESS and middle ear surgeries.

    Surgical endoscopy revolutionized the management of disease in nearly every surgical field, including rhinology. Endoscopy offered several advantages for the surgical management of rhinologic disease. However, it had a distinct disadvantage compared to direct vision, namely loss of binocular vision. Two-dimensional (2D) endoscopy limited depth perception, widely regarded as an important parameter for accurate and efficient movements during surgery. Three-dimensional (3D) endoscopic visualization has been actively pursued for decades by endoscopic surgeons in multiple surgical specialties. However, its clinical role has been limited due to technical limitations as well as successful adaptation by endoscopic surgeons to monocular cues offered by 2D technology. Until recently, stereoscopic technology included variations of dual channel video, dual chip-on-the-tip, and shutter mechanism, as well as various 3D displays. Over the past decade a novel 3D endoscopic technology was introduced. This technology used a lenticular array of lenses in front of a single video chip at the distal end of an endoscope to generate a stereoscopic view of the surgical field. Also known as the 'insect eye' technology since it mimics the compound eye of arthropods, this endoscope has reinvigorated the field of 3D endoscopic surgery. Recent developments in 3D endoscopy hold much promise for all surgical subspecialties, particularly endoscopic sinus and skull-base surgery.

    Full Text Available Objective. We report the first utilisation of transnasal marsupialization to treat a keratocystic odontogenic tumor in the maxillary sinus of a 37-year-old man. Case Report. A 37-year-old man presented with a nasal discharge and right odontalgia. Computed tomography revealed an expanding cystic lesion with a calcificated wall containing an impacted tooth in the right maxillary sinus. The diagnosis was keratocystic odontogenic tumor. Transnasal marsupialization was performed using endoscopic sinus surgery to enlarge the maxillary ostium and remove a portion of the cystic wall. Pathological findings included lining squamous epithelium and inflammation. The remaining tumor shrank, becoming free of infection after surgery, without proliferation. Conclusion. Transnasal marsupialization using endoscopic sinus surgery is effective in treating keratocystic odontogenic tumors. It offers minimal surgical invasion and reductive change, making it advantageous for complete removal with fewer complications in the bones and surrounding tissue in the case of secondary surgery.

    Functional endoscopic sinus surgery is a common procedure performed within otolaryngology, but it carries potential for significant life-changing complications. It is therefore essential that trainees undergo adequate training. The European Working Time Directive has led to reduced operating time for the trainee surgeon. With variable access and the cost implications associated with cadaveric specimens, simulation can be an invaluable educational resource in surgical training. The current literature regarding the various simulation methodologies that have been used in functional endoscopic sinus surgery training is discussed. A literature search was conducted using the key words 'nasal', 'nasal polyps', 'endoscope', 'education and simulation', 'endoscopic sinus surgery' and 'training'. Twelve articles were identified; of these, eight trialled the use of simulators, two utilised ovine models and two used task trainers. Simulation has shown benefit in functional endoscopic sinus surgery training; however, a robust platform accessible to ENT trainees is lacking.

    Full Text Available Bone suture in lateral sinus lift has four indications. Three of them depend on creating a hole in the lateral maxillary sinus wall above the antrostomy window for securing the elevated medial maxillary sinus membrane to manage perforated Schneiderian membrane. Covering the buccal antrostomy window with the buccal fat pad (BFP for better nourishment of the inserted graft and as an alternative for bone tags in fixation of collagen membrane has been reported previously. A new indication for firmly anchoring the BFP to the medial maxillary sinus wall as the last resort for the management of perforated Schneiderian membrane is explained in this article.

    Investigations into the distribution of sinus irrigations have been limited by labor-intensive methodologies that do not capture the full dynamics of irrigation flow. The purpose of this study was to validate the accuracy of a computational fluid dynamics (CFD) model for sinonasal irrigations through a cadaveric experiment. Endoscopic sinus surgery was performed on 2 fresh cadavers to open all 8 sinuses, including a Draf III procedure for cadaver 1, and Draf IIb frontal sinusotomies for cadaver 2. Computed tomography maxillofacial scans were obtained preoperatively and postoperatively, from which CFD models were created. Blue-dyed saline in a 240-mL squeeze bottle was used to irrigate cadaver sinuses at 60 mL/second (120 mL per side, over 2 seconds). These parameters were replicated in CFD simulations. Endoscopes were placed through trephinations drilled through the anterior walls of the maxillary and frontal sinuses, and sphenoid roofs. Irrigation flow into the maxillary, frontal, and sphenoid sinuses was graded both ipsilateral and contralateral to the side of nasal irrigation, and then compared with the CFD simulations. In both cadavers, preoperative and postoperative irrigation flow into maxillary, frontal, and sphenoid sinuses matched extremely well when comparing the CFD models and cadaver endoscopic videos. For cadaver 1, there was 100% concordance between the CFD model and cadaver videos, and 83% concordance for cadaver 2. This cadaveric experiment provided potential validation of the CFD model for simulating saline irrigation flow into the maxillary, frontal, and sphenoid sinuses before and after sinus surgery. © 2016 ARS-AAOA, LLC.

    The objective of the study is to investigate the impact of receiving daily WeChat services on one's cell phone on adherence to corticosteroid nasal spray treatment in chronic rhinosinusitis (CRS) patients after functional endoscopic sinus surgery (FESS). This study was a two-arm, randomized, follow-up investigation. Patients with chronic rhinosinusitis with/without nasal polyps following bilateral FESS were randomised to receive, or to not receive, daily WeChat service on their cell phone to take corticosteroid nasal spray treatment. A prescription of budesonide aqueous nasal spray 128 µg bid was given to all the subjects. Then they returned to the clinic after 30, 60, 90 days. The primary study outcome was adherence to nasal spray treatment, whereas secondary outcomes were change in endoscopic findings and SinoNasal Outcome Test-20 (SNOT-20). On the whole, there was a significant inter-group difference in the change of adherence rate (F = 90.88, p = 0.000). The WeChat group had much higher adherence rate than the control group during the follow-up. In terms of postoperative endoscopic scores and SNOT-20, except granulation score, no significant differences were observed between the two randomization groups. WeChat services are already after a short period of observation associated with improved adherence to corticosteroid nasal spray treatment in CRS patients after FESS.

    Alteration of the bony architecture of the sinus cavities has been observed in chronic sinusitis. Plasticity of the ethmoid sinus framework after endoscopic surgery, however, is a newly described entity. The objective of this study was to determine the incidence and extent of changes in ethmoid size after ethmoidectomy. Retrospective review performed at an academic medical center. Computed tomography scans performed from 2006 through 2007 at the Massachusetts Eye and Ear Infirmary (n = 5,131) were reviewed to identify 100 consecutive patients who underwent sinus surgery and met inclusion criteria. Seven dimensions were measured for each pre- and postoperative scan (n = 200) using Voxar 3D software. Computed tomography scans performed before and 2 to 37 months after ethmoidectomy demonstrated a decrease of 1.1 +/- 1.6 mm in mean ethmoid cavity width at the level of the cribriform plate and posterior globe after surgery (P 1 mm decrease in mean ethmoid width, and six patients (6%) had a decrease of >2 mm (mean 3.1 +/- 0.9 mm). These findings seemed to be the result of postoperative bowing of the medial ethmoid walls with a corresponding increase in orbital volume. These volumetric changes resulted in a postoperative subclinical retrodisplacement (enophthalmos) of the globes (mean 0.2 +/- 0.8 mm, P = .008). The extent of surgery, including performance of frontal recess dissection (P = .007) and total ethmoidectomy (P = .021) were found to be independent predictors of the observed changes in sinus dimensions. Postsurgical plasticity of the ethmoid cavity is a new concept supported by observed changes in sinus dimensions after ethmoidectomy. These changes may reflect a loss of internal structural support and forces of contracture during the postoperative healing period.

    Functional endoscopic sinus surgery (ESS) has become the procedure of choice for surgical treatment of chronic rhinosinusitis. Does the published literature support the claims of greater efficacy than medical treatment alone or older sinus procedures? To analyze the methodology of the published literature regarding the efficacy of ESS. MEDLINE search for primary studies published in 1987 through 2001, written in the English language, reporting results on more than 100 patients, using the MeSH (medical subject headings) terms sinusitis [subheadings surgery or therapy] and endoscopy. Of 512 studies initially identified, 29 studies met the inclusion and exclusion criteria for further assessment of methodologic criteria. An additional 6 studies were found when the reference lists of reviews or included studies were searched. Articles were evaluated for 4 core (inclusion/exclusion criteria, control group, intervention, and clear outcome measure) methodologic criteria essential to the determination of efficacy of ESS. Eight additional methodologic criteria were also used to rate the articles. Three studies met all 4 core methodologic criteria. Only 4 of 35 studies used a control group to evaluate efficacy of ESS to treat chronic sinusitis. Mean number of criteria met was 7.2, with a range of 2 to 11. Absence of a control group is the most important reason that studies are unable to scientifically assess the comparative efficacy of ESS to medical therapy or other sinus procedures. The methodologic criteria described here can be used to evaluate studies of interventions for other disorders.

    Impaired olfaction is associated with a volume decrease in the olfactory bulb as well as in the gray matter of cortical olfactory areas. On the other hand, restitution of an impaired olfaction results in a regain of volume in these regions. Studies investigating similar changes in the cerebral white matter are virtually not existent. The aim of this prospective study therefore was to investigate cerebral white matter using magnetic resonance diffusion tensor imaging (DTI). 31 patients (54±13years) with olfactory impairment (chronic rhinosinusitis) and planned functional endoscopic sinus surgery (FESS) were included. Magnetic resonance imaging (MRI) data sets were acquired pre-operatively and 3months after surgery. Pre- and postoperative olfactory testing was performed to assess the olfactory threshold, discrimination, and identification (TDI) score. A significant postoperative TDI improvement by 9.06±8.81 points was observed. Two groups were subsequently formed - one with relevant postoperative olfactory gain (ΔTDI≥10 points, 12 patients) and one without gain (ΔTDImatter below the left inferior temporal sulcus. Tract-specific diffusion property analysis revealed significant group differences in the cingulate cortex in spatial relationship to the perisplenial cortex. Overall, this prospective study indicates structural changes in white matter after postoperative restoration of olfaction. Copyright © 2017 IBRO. Published by Elsevier Ltd. All rights reserved.

    Long-term retrospective evaluation was performed of computed tomography (CT) images and endoscopic findings after endoscopic sinus surgery for 88 cases of chronic pediatric sinusitis with nasal polyps. The objective was to determine the appropriate duration of such postoperative evaluation for children. Fifty-one patients had both sinusitis and nasal polyps (BSP group), and the surgical procedure was decided in consideration of each patient's age (for less than 10 years of age, polypectomy (n=12); for 10-13 years old, anterior ethmoidectomy plus opening of the fontanelle and nasofrontal duct (n=20); and for serious cases older than 13 years, total sinusectomy (n=19)). On the other hand, for cases of unilateral sinusitis with antrochoanal polyps (USP group), anterior ethmoidectomy plus opening of the fontanelle was performed regardless of the patient's age (n=37, 5-15 years old). The postoperative endoscopic findings indicated that the polyps had been eliminated in approximately 91% of total patients. Good postoperative findings of CT images in most patients of USP group are observed at one year after the operation like the same of the postoperative course of adult chronic sinusitis. On the other hand CT images in BSP group evaluated one year after the operation were rated as unchanged or worsened in approximately half of the patients. However, at 4 years after the operation nearly all the patients were rated as improved or better. In addition, comparison of the age at final observation and the postoperative course found a striking decrease in the proportion of unchanged and worsened patients aged 12 and above. Accordingly, it was concluded that there is difference of healing process after the operation between USP and BSP group. Postoperative evaluation of BSP group should be performed for 4 years and up to an age of at least 12 years although post-ESS following of USP group is similar to that of adult sinusitis.

    Transoral robotic surgery (TORS) has been proven to be safe and to yield acceptable oncological and functional outcomes for surgery of the oropharynx, hypopharynx, supraglottis, and glottis. TORS has been successful at reducing morbidity, improving quality of life, and providing access to areas that previously required mandibulotomy or other more radical approaches in the past. This has changed the paradigm of management of tumors in these anatomic locations. In this article, the authors review the recent literature discussing the role of robotic surgery in managing sinonasal and skull base pathology and discuss its current advantages and limitations.

    To assess the value of oxymetazoline used in nasal endoscopic sinus surgery (ESS). The effect of oxymetazoline on 68 patients pulse, cilium mottom and rebound phenomenon during ESS were observed. Pulse and cilium motion are no significant difference after using oxymetazoline. Oxymetazoline reduces about 59% nasal mucosal blood flow and acts over 6 hours. Oxymetazoline used as nasal decongestant and anesthesia assistant is safe and effect in ESS as routine.

    Full Text Available Objective: To measure the intra-sinus pressure and the maxillary sinus functional efficiency (MSFE in individuals with chronic facial pain after conservative or conventional endoscopic maxillary surgery, as well as in controls. Method: Sinus manometry was performed 5 times during inhalation. Results: The resemblance of pressure values comparing those treated with minimally invasive surgery and controls was remarkable, while traditional surgery significantly decreased intrasinusal pressures. The MSFE was 100% in the three tested times for controls, close to that in those submitted to minimally invasive surgery (98.3%, 98.8%, and 98.0% and significantly impaired after conventional surgery (48.8%, 52.1%, 48.5 %, p<0.01. All patients submitted to minimally invasive surgery remained pain-free after three months of surgery, relative to 46.7% of the submitted to conventional surgery (p<0.05. Conclusion: Minimally invasive sinus surgery is associated with functionality of the chambers that resemble what is found in normal individuals.

    The objective was to quantify bone formation within autogenous bone grafts and autogenous bone grafts in combination with platelet-rich plasma obtained either from apheresis or centrifugation using computed tomography. This prospective, double-blind study was conducted in 34 male and female adult patients (mean age of 28 years and 8 months), with either unilateral or bilateral pneumatization of the maxillary sinuses, requiring bone graft for dental implant. All patients were submitted to computed tomography examinations prior and six months after sinus lift surgery. Fifty-three maxillary sinuses were operated and divided into three distinct groups: autogenous bone graft, autogenous bone graft in combination with platelet-rich plasma obtained by centrifugation, and autogenous bone graft in combination with platelet-rich plasma obtained by apheresis. The results showed that computed tomography demonstrated bone growth in height and width between the initial and the follow-up computed tomography scans in all three groups. However, no statistical difference was found either for bone height or width. It was concluded that clinical evidence demonstrates the effectiveness of autogenous bone grafts, particularly when used in combination with bone growth factors such as platelet-rich plasma, which allow prosthetic and functional restoration of maxillofacial structures through fixation of dental implants.

    Virtual surgical training systems are of growing value. Current prototypes for endonasal sinus surgery simulation are very expensive or lack running stability. No reliable system is available to a notable number of users yet. The purpose of this work was to develop a dependable simulator running on standard PC hardware including a detailed anatomic model, realistic tools and handling, stereoscopic view, and force feedback. Descriptive. A three-dimensional voxel model was created based on a high-resolution computed tomography study of a human skull, from which the bony structures were segmented. The mucosa and organs at risk were added manually. The model may be manipulated with virtual surgical tools controlled with a low-cost haptic device, which is also used to adjust microscopic or endoscopic views. Visualization, haptic rendering, and tissue removal are represented with subvoxel resolution. The handling of the model is convincing. The haptic device provides a realistic feeling regarding the interaction between tool tip and anatomy. Three-dimensional orientation and the look and feel of virtual surgical interventions get close to reality. The newly developed system is a stable, fully operational simulator for sinus surgery based on standard PC hardware. Besides the limitations of a low-cost haptic device, the presented system is highly realistic regarding anatomy, visualization, manipulation, and the appearance of the tools. It is mainly intended for gaining surgical anatomy knowledge and for training navigation in a complex anatomical environment. Learning effects, including motor skills, have yet to be quantified.

    Disagreement exists about the relationship between Lund-Mackay CT scores (LMCTS) and quality-of-life outcome (QoL) measures. We investigated whether preoperative LMCTS are associated with preoperative QoL, and whether LMCTS is predictive of postoperative QoL outcomes in chronic rhinosinusitis (CRS) patients. Adult patients with medically recalcitrant CRS (n = 665) were enrolled in a prospective, observational cohort study. Preoperative LMCTS and pre- and postoperative self-reported QoL outcomes (22-item Sino-Nasal Outcomes Test [SNOT-22]) were collected and evaluated over 12 months. Five hundred sixty-eight patients met the inclusion criteria. Longitudinal linear mixed-effects modeling was used to investigate the effect of LMCTS on QoL after functional endoscopic sinus surgery (FESS). Preoperative LMCTS were significantly associated with preoperative SNOT-22 scores (p preoperative LMCTS quartile had the lowest mean change in SNOT-22 scores at 12 months (16.8 points; 95% confidence interval [CI], 12.2-21.3). Patients in the second and third lowest preoperative LMCTS quartiles had mean changes at 12 months of 21.1 points (95% CI, 16.7-25.4) and 23.1 points (95% CI, 18.3-27.9). Patients in the highest preoperative LMCTS quartile had the greatest improvement in SNOT-22 scores after FESS (29.9 points; 95% CI, 24.9-34.8). The difference in QoL change at 12 months between the highest and lowest preoperative LMCTS quartiles was 13.1 points (95% CI, 6.0-20.2; p preoperative LMCTS correlate with preoperative extranasal and rhinologic symptom severity and that the LMCTS is an indicator of postsurgical QoL outcomes for medically recalcitrant chronic rhinosinusitis patients in a large tertiary otolaryngology setting. © 2018 ARS-AAOA, LLC.

    Topical sinus irrigations play a critical role in the management of sinonasal disease, and the improvement in irrigant penetration into the sinuses postoperatively greatly contributes to the success of endoscopic sinus surgery. Prior investigations on postoperative sinus irrigations have been mostly limited to cadaver studies, which are labor intensive and do not capture the full dynamics of the flows. A pilot study was conducted to investigate the impact of surgery on sinus irrigation through computational fluid dynamics (CFD) simulations. Retrospective computational study. Pre- and postoperative computed tomography (CT) scans were obtained on a patient who underwent standard endoscopic surgeries for all sinuses, including a Draf III frontal sinusotomy. CT-based pre- and postoperative CFD models then simulated irrigations of 120 mL saline per nostril at 12 mL/s (typical of Sinugator) and 60 mL/s (SinusRinse Bottle), in two head positions: face parallel and at a 45° angle to the ground. Overall, surgery most significantly improved frontal sinus irrigation, but surprisingly resulted in less maxillary and ethmoid sinuses penetration. This may due to the partial removal of the septum during the Draf III, causing most fluid to exit prematurely across the resected septum. Higher flow rate slightly improved ethmoid sinus irrigation, but resulted in less preoperative contralateral maxillary sinus penetration. CFD modeling of sinonasal irrigations is a novel technique for evaluating irrigant penetration of individual sinus cavities. It may prove useful in determining the optimal degree of surgery or the ideal irrigation strategy to allow for maximal and targeted sinus irrigant penetration.

    Although the use of image guidance surgery (IGS) is standard practice in developed countries, it has not been in use in Indian Otolaryngology ever since its clinical inception in 1994. Some clinically interesting applications, relevant indications, practical tips and results in the Indian context are presented. Usage technique and data presentation. Indications based on AAO-HNS 2002 guidelines seem valid, and though the accuracy parameters remain still guarded, in line with the best technology available, based on the evidences of scattered reports and expert opinions, the use of navigation can be recommended as state of the art. IGS provides reliable information to a sinus surgeon in difficult circumstances. Its adaptation fortunately does not require a significant learning curve as it does not change the methodology of the surgical procedure. It can be an excellent teaching tool, but its use does not replace proper surgical training.

    2005-07-01

    Endoscopic sinus surgery is one of the most common surgical procedures in otolaryngology. However, the location of the orbit and intracranial contents in close proximity to the paranasal sinuses makes endoscopic sinus surgery potentially hazardous. Otolaryngologists have employed computer-aided surgery, or image-guided surgery, over the past two decades to enhance surgeon confidence, allow more thorough surgical dissections and possibly reduce the complication rate of endoscopic sinus surgery. Computer-aided surgery utilizes preoperative imaging to provide real-time localization of surgical instruments in the surgical field. Although computer-aided surgery originated in the neurosurgical realm, otolaryngologists soon appreciated that this technology could assist in identifying critical orbital or intracranial structures surrounding the paranasal sinuses, and potentially aid in decreasing complications. In this article, the history of image-guidance systems and their application to surgery of the paranasal sinuses and skull base will be reviewed. The components of computer-aided surgery systems and the currently available technologies for surgical instrument tracking are discussed, as well as the advantages and disadvantages of each of the tracking technologies. In addition, issues relating to the accuracy of image-guidance systems are examined. A number of institutional series noting surgeon experience with computer-aided surgery in the domain of paranasal sinus surgery are reviewed. Furthermore, the authors evaluate the utility of image-guidance technology beyond the paranasal sinuses and skull base, such as its use in surgery of the pituitary gland and pterygopalatine fossa, research and resident education. Finally, potential future applications of computer-aided surgery technology are discussed.

Balloons for catheter dilation of paranasal sinuses were introduced in 2005, allowing sinus surgery to be safely performed either in the operating room or the office care setting, under local anesthesia. This change in care setting has raised concerns of overuse or expanded indications for sinus surgery. This study was thus designed to evaluate changes in surgical volumes in the United States, for the period 2006–2011, and to evaluate the impact of the sinus balloons on surgical practice. Methods: The MarketScan® Commercial Claims and Encounter Database was queried for the period 2006 to 2011 using CRS International Classification of Diseases, Ninth Revision codes (473.X and sinus surgery US-based Common Procedural Terminology (CPT codes (endoscopic sinus surgery: CPT codes 31254–31294 and 31299; balloon catheter dilation: CPT codes 31295–31297. MarketScan's projection methodology was applied to estimate the nationwide prevalence of CRS and the incidence of sinus surgery. Procedural case mix and total average payment per surgery were analyzed. Results: From 2006 to 2011, the yearly prevalence of CRS and sinus surgery volume remained flat with ~430 patients with CRS per 100,000 in the employer-sponsored insured population, of which ~117/100,000 underwent surgery. In 2006, 2.69 paranasal sinuses (95% confidence interval [95% CI]: 2.65–2.71 were treated during each individual sinus surgery, with an additional 1.11 nasal procedures (95% CI: 1.08–1.13 performed concurrently.

    Routine histopathological assessment is standard practice for nasal polyp specimens obtained during endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS). Retrospective studies suggest that routine histopathology of nasal polyps shows few unexpected diagnoses that alter patient management. Our objective was to study the use of routine pathological analysis, and its cost to the healthcare system, in a prospective manner. A multicenter prospective assessment was performed from data collected between 2007 and 2013. Only cases of patients undergoing ESS for bilateral CRS were included. We excluded unilateral disease cases, and cases in which diagnoses other than polyps were suspected either preoperatively or intraoperatively. We then compared the preoperative diagnosis with the final histopathology and identified the rate of unexpected pathologies. A cost analysis was performed. Only 4 of 866 pathological specimens were identified as having a clinically significant unexpected diagnosis. All unexpected pathologies in this series were benign. These 4 cases account for 0.46% of all specimens reviewed. This translates to a number needed to screen of 217 cases of bilateral CRS to discover 1 unexpected pathology. The associated cost for making an unexpected diagnosis was $19,192.73. Routine histopathology of nasal polyps in ESS for bilateral CRS with polyps yields few unexpected and management-altering diagnoses. It carries a significant cost to the healthcare system. In cases of bilateral CRS with no other concerning clinical features, clinicians should exercise judgment in submitting polyp specimens for pathology rather than routinely sending polyps for histopathologic analysis. © 2014 ARS-AAOA, LLC.

    Full Text Available OBJECTIVE: To compare frontal sinus cranialization to obliteration for future prevention of secondary mucocele formation following open surgery for benign lesions of the frontal sinus. STUDY DESIGN: Retrospective case series. SETTING: Tertiary academic medical center. PATIENTS: Sixty-nine patients operated for benign frontal sinus pathology between 1994 and 2011. INTERVENTIONS: Open excision of benign frontal sinus pathology followed by either frontal obliteration (n = 41, 59% or frontal cranialization (n = 28, 41%. MAIN OUTCOME MEASURES: The prevalence of post-surgical complications and secondary mucocele formation were compiled. RESULTS: Pathologies included osteoma (n = 34, 49%, mucocele (n = 27, 39%, fibrous dysplasia (n = 6, 9%, and encephalocele (n = 2, 3%. Complications included skin infections (n = 6, postoperative cutaneous fistula (n = 1, telecanthus (n = 4, diplopia (n = 3, nasal deformity (n = 2 and epiphora (n = 1. None of the patients suffered from postoperative CSF leak, meningitis or pneumocephalus. Six patients, all of whom had previously undergone frontal sinus obliteration, required revision surgery due to secondary mucocele formation. Statistical analysis using non-inferiority test reveal that cranialization of the frontal sinus is non-inferior to obliteration for preventing secondary mucocele formation (P<0.0001. CONCLUSION: Cranialization of the frontal sinus appears to be a good option for prevention of secondary mucocele development after open excision of benign frontal sinus lesions.

    colonisations often occur with bacteria of identical genotype. This may be due to re-colonisation from the patient's paranasal sinuses. In our study, we found that approximately two-thirds of CF patients having sinus surgery (FESS) had growth of CF-lung-pathogenic Gram-negative bacteria in their sinuses...... conditions for adapting to the environment in the lungs. In the presence of bacteria, the environment of the sinuses differs from that of the lower respiratory tract by having a higher immunoglobulin A (IgA): IgG ratio, and reduced inflammation. We found a significant correlation between the concentration....... By this strategy, sinus bacteria could be eradicated in a large proportion of patients. Essentially, growth of CF-pathogenic bacteria from the lower respiratory tract was decreased following the treatment. Furthermore, a number of patients have been free from CF-pathogenic bacteria for more than one year after...

    OBJECTIVE There are no guidelines for the management of postoperative lateral sinus thrombosis following posterior fossa surgery. Introducing treatment-dose anticoagulant therapy during the immediate postoperative period increases the risk of intracranial bleeding. This study assessed the incidence of and risk factors associated with postoperative lateral sinus thrombosis and the complications related to thrombosis and/or anticoagulation. METHODS This study was a retrospective monocentric analysis of adult patients who underwent surgical removal of a posterior fossa space-occupying lesion with available postoperative imaging. Postoperative lateral sinus thrombosis was defined as a T2 * hypointensity within the venous sinus and/or a filling defect on postcontrast MRI or CT scan. RESULTS Among 180 patients, 12 (6.7%; 95% CI 3.0-10.4) were found to have lateral sinus thrombosis on postoperative imaging, none of whom were symptomatic. Unadjusted risk factors for postoperative lateral sinus thrombosis were a history of deep venous thrombosis (p = 0.016), oral contraceptive pill (p = 0.004), midline surgical approach (p = 0.035), and surgical exposure of the sinus (p < 0.001). Seven of the patients (58.3%) with a postoperative lateral sinus thrombosis received immediate treatment-dose anticoagulant therapy. Lateral sinus recanalization occurred radiologically at a mean time of 272 ± 23 days in 85.7% of patients (6 of 7) undergoing treatment-dose anticoagulant therapy and in 20% of patients (1 of 5) not receiving treatment-dose anticoagulant therapy. Postoperative complications occurred in 56.2% of patients (9 of 16) who received treatment-dose curative anticoagulant therapy and in 27% of patients (45 of 164) who did not. CONCLUSIONS Incidental radiological lateral sinus thrombosis following posterior fossa surgery has an incidence of 6.7%. To further define the benefit-to-risk ratio of a treatment-dose anticoagulant therapy, a prospective trial should be considered.

    A slow-growing frontal sinus osteoma has been followed up since the year 2001 by clinical, endoscopic, and radiological examination in the Department of Otolaryngology, New Medical Centre Specialty Hospital, Abu Dhabi, for 10 years until the year 2010. The last computed tomography scan of paranasal sinuses was done on April 5, 2010, which revealed increasing size of the osteoma by 38.1 mm; and it has become symptomatic. No specific cause of the sudden change of growth of the osteoma could be evaluated from the history and clinical examination. There was an increase in the frequency of headache and feeling of pressure in the forehead. Choice of surgical approach was difficult in this popular era of endonasal endoscopic sinus approach. A great deal of effort was made after reviewing the literature and consultation with the radiologist and neurosurgeon to accept the bicoronal osteoplastic flap approach. A broad-based posterior frontal sinus is found to be ideal for external approach. Copyright © 2011 Elsevier Inc. All rights reserved.

    Wound healing after endoscopic sinus surgery may result in adhesion formation. Hyaluronic acid may prevent synechiae development. A systematic review was performed to evaluate the current evidence on the clinical efficacy of hyaluronic acid applied to the nasal cavity after sinus surgery. Studies using hyaluronic acid as an adjunct treatment following endoscopic sinus surgery for chronic rhinosinusitis were identified. The primary outcome was adhesion formation rates. A meta-analysis was performed on adhesion event frequency. Secondary outcome measures included other endoscopic findings and patient-reported outcomes. Thirteen studies (501 patients) met the selection criteria. A meta-analysis of adhesion formation frequency on endoscopy demonstrated a lower risk ratio in the hyaluronic acid intervention group (42 out of 283 cases) compared to the control group (81 out of 282) of 0.52 (95 per cent confidence interval = 0.37-0.72). Hyaluronic acid use was not associated with any significant adverse events. Hyaluronic acid appears to be clinically safe and well tolerated, and may be useful in the early stages after sinus surgery to limit adhesion rate. Further research, including larger randomised controlled trials, is required to evaluate patient- and clinician-reported outcomes of hyaluronic acid post sinus surgery.

    To describe a rare case of odontogenic brain abscess. A healthy, 35-year-old male had two dental implants placed in a simultaneously augmented maxillary sinus. One implant failed and the patient developed a maxillary sinusitis that failed to improve following antibiotic treatment at home. The neglected sinus infection led to formation of a brain abscess. The patient was hospitalised only when he had pan sinusitis with neurological signs. Symptoms were headache attacks, a subfebrile fever and a purulent secretion from the left nostril. The osteomeatal complex was blocked, the maxillary sinus was filled with pus and the Schneiderian membrane thickened. The patient was treated with intravenous antibiotic treatment. Computerised tomography (CT) and magnetic resonance imaging (MRI) scans and functional endoscopic sinus surgery (FESS), were implemented. When his conditions worsened, the patient underwent a left frontal mini craniotomy. Following the craniotomy and antibiotic treatment, there was a gradual resolution and the patient was dismissed after 2 months in hospital with no neurological deficit or signs of sinusitis. Maxillary sinusitis following dental implant insertion and concomitant maxillary sinus elevation should be treated immediately and thoroughly since untreated sinusitis may cause life-threatening situations such as a brain abscess. In case of severe infection, clinicians should refer immediately the patient to hospital specialists.

    Chronic rhinosinusitis is a common disease process in humans; however, in the primate population of gorillas, it has rarely been described. This case describes lifesaving sinus surgery on a critically ill gorilla performed by a human otolaryngology team in collaboration with the gorilla's veterinary medicine team. The 35-year-old western silverback gorilla was treated for 3 months with aggressive medical therapy for a worsening sinus infection. When his condition became severe, a computed tomography (CT) scan was performed showing advanced chronic rhinosinusitis with nasal polyps vs other masses and some bone erosion. As his condition deteriorated further, a tertiary otolaryngology team performed sinus surgery using the latest technology available, including image guidance, steroid-eluting sinus stents, and balloon sinus dilation. The postoperative course was complicated by subcutaneous infection and eventual fistulization. Fortunately, with culture-directed antibiotic therapy his condition gradually improved. One year later he required revision sinus surgery. At that point allergy testing was performed followed by appropriate allergy medical therapy. Now, 3 years out from his initial surgery, he continues to do well and has fathered a young female gorilla. This case represents a unique collaboration between human physicians and veterinarians. The combined medical approach was critical to heal this ailing gorilla. This case discusses many of the challenges and offers recommendations for physicians who may be involved with similar care of animals in the future. The success of the surgical and medical treatment of this gorilla's life-threatening sinus infection required many experts, careful planning, and corporate generosity. The interaction between human and animal medicine would not have been successful without the close and trusting collaborations between human and veterinary health providers.

    Two cases of sphenoid sinus mucocele are described. Diagnosis was based on insidious orbital symptoms, apex orbital syndrome, followed by CT and MRI examinations. In one case the mucocele was preceded by seven years of a successfully treated undifferentiated nasopharyngeal carcionma. Simple transnasal endoscopic drainage of the mucoceles gave good results, although a monocular blindness of long standing was irreversible. A high level of suspicion, combined with modern imaging techniques and prompt surgical intervention, are the prerequisites for avoiding persisting sequelae. 28 refs., 5 figs.

    The optimal management of frontal sinus fractures remains controversial. Fortunately, the severity of these injuries has diminished with more stringent auto-safety regulations, changing the treatment paradigms used to repair these injuries. Appropriate patient selection and close follow-up may allow for conservative management strategies when dealing with frontal sinus fractures, largely replacing the more morbid and invasive techniques that have been the mainstay for years. Because acute and delayed sequelae can arise after the initial injury, patients should be thoroughly counseled about the importance of follow-up and the need to seek medical care if they develop any concerning signs or symptoms.

    To compare the efficacy of dexpanthenol spray and saline irrigation in the postoperative care of sinusitis patients following endoscopic sinus surgery (ESS). One hundred twenty eight sinusitis patients undergoing ESS were randomly allocated to receive dexpanthenol spray (Mar plus) or saline irrigation twice a day for 4 weeks after the operation. Total nasal symptom score, crusting, infection, compliance, and patient satisfaction were evaluated at 1, 2-3, 4-6, and 12 weeks. Mucociliary clearance was assessed with the saccharin test before ESS and at the last visit. One hundred ten patients remained at the present study termination. Chi-square test and Mann-Whitney U test were employed. Total nasal symptom score, mucociliary clearance, and infection improved in both groups after the operation. The dexpanthenol group resulted in a better mucociliary clearance than saline irrigation (9.93 +/- 6.04 vs. 12.38 +/- 9.32 min, p = 0.43). Saline irrigation resulted in a greater reduction of post nasal drip than dexpanthenol at the first visit (74% vs. 87%, p = 0.04). Compliance and patient satisfaction were comparable. The efficacy of dexpanthenol was comparable to nasal saline irrigation in the postoperative care of sinusitis patients following endoscopic sinus surgery. Dexpanthenol is an alternative treatment, which may be useful in young children and complicated cases.

    Chronic rhinosinusitis (CRS) is an inflammation of the nose and paranasal sinuses lasting for ≥12 weeks. Endoscopic sinus surgery (ESS) is considered during difficult to treat CRS. The minimally invasive technique focuses on the transition areas rather than on the ostia. The aim of this study was to evaluate symptoms, the number of acute sinusitis episodes, and satisfaction after ESS with either preservation or enlargement of the maxillary sinus ostium. Thirty patients with moderate nonpolypous CRS were enrolled. Uncinectomy only and additional middle meatal antrostomy were randomized for each side of each patient and performed single blindly. The symptoms questionnaires were filled at four time intervals. Significant symptom reduction was achieved independently of operation technique. The number of acute sinusitis episodes indicating the exacerbation rate decreased significantly at 9 and, on average, 68 months postoperatively. However, the exacerbation rate began to increase after 9 months postoperatively. Three revisions were performed on the side with uncinectomy only and one on the side with additional antrostomy. Most patients reported good satisfaction with both procedures. There was a trend for patients with asthma and/or job exposure to report insignificantly more frequently no satisfaction with surgery, especially with the uncinectomy-only procedure. Both procedures seem to be efficient in providing symptom relief and satisfaction. More studies are needed to evaluate if patients with risk factors benefit more from an ostium-enlarging procedure.

    Tumors of the nasal cavity and paranasal sinuses present a challenge to treat them. A combination of surgery and radiation therapy can improve treatment outcomes in 49-56% [1, 2] of the patients with locally advanced nasal cavity and paranasal sinus cancer. The midface reconstruction poses a formidable challenge to the reconstructive surgeon due to the region's complex skeletal and soft-tissue anatomy. The rehabilitation program including the reconstruction of the resected orbital walls using the porous and mesh implants from titanium nickelid (TiNi) was developed at the Cancer Research institute jointly with the Research Institute of Medical Materials. The technique was proven effective, allowing the natural position of the eye and visual function to be preserved in 90% [1-3] of the patients. A long period of reparative processes and risk of developing inflammation in the implant area, as well as the need to decrease length of surgery, contributed to the development of a novel approach to repairing the midface bone structures using the implant based on the microporous wire and TiNi mesh. Eighteen patients with nasal cavity and paranasal sinus cancer were treated using the combined thin implants. The novel technique allowed the time of the implant installation to be reduced to 5-10 min. The structure of the implant contributed to prevention of inflammatory processes in 97% [1, 2] of cases. Thus, the natural position of the eyeball and visual function were preserved in 100% [1, 3, 4] of patients. The use of the TiNi implants in reconstructive surgery for patients with nasal cavity and paranasal sinus cancer led to reduced time of surgery and rehabilitation, increased level of social adaptation of patients and improved cosmetic and functional results.

    Purpose: The purpose of this study was to define objective and reproducible standards for the quality of CT images as a function of radiation doses and therapeutic validity. Materials and methods: CT images of the paranasal sinuses of 145 patients (77 female, 68 male; 5-83 years old; mean age, 39.9 years) were classified both subjectively (with a view toward their validity for the planning of functional endoscopic sinus surgery, FESS) and objectively by defining the pixel noise (the standard deviation, STD, of the CT number) in a homogeneous region of interest (ROI), centered on the M. masseter and on the frontal lobe. These measurements were then compared to measurements obtained from scan images of a water-filled Perspex phantom. Results: The pixel noise measured in the phantom images was nearly identical to the respective values on the M. masseter on the patient images. The use of an edge-enhancing reconstruction algorithm and low-dose protocols, with a pixel noise amounting to 70-90 Hounsfield Units (HU), are indicated for children, chronic sinusitis, and septum deviation, while standard protocols, with a pixel noise of 50-70 HU, are recommended for the preoperative planning and postoperative control of FESS. The pixel noise for high-dose protocols is less than 50 HU; nonetheless, such protocols should generally be avoided. Conclusion: The pixel noise measured in a water-filled Perspex phantom is indicative of the clinical potential and image quality of paranasal sinus CT scans. Alternatively, the M. masseter can be chosen as an ROI to measure the pixel noise in order to obtain a rough estimate of the image quality or radiation dose class.

    To examine the effect of concurrent endoscopic sinus surgery (ESS) on the postoperative course of cosmetic rhinoplasty (CR), identify any specific contraindications, and to develop more useful treatment regimen in patients undergoing concurrent ESS and CR. Retrospective case-control study. Consecutive patients undergoing CR (performed by the principal investigator (PI) in a tertiary care academic practice) at the same operative setting as ESS from June 2004-June 2007 were identified. Additionally, patients undergoing CR (also by the PI) without ESS over the same time period (matched for gender, age, and rhinoplasty approach and techniques) were identified and used as control subjects. The office and hospital charts of these patients were reviewed for details of pre-, intra-, peri-, and postoperative care, preoperative CT scans as well as for patient and physician observations. Specifically noted were details regarding the type of cosmetic changes sought, course of symptoms of chronic sinusitis, prior treatment, surgical techniques used for both ESS and CR, and postoperative treatment with antibiotics and corticosteroids. Additionally, a literature review of articles describing concurrent CR and ESS was performed. Thirteen patients were identified who underwent ESS at the same time as CR. There were no cases of cerebrospinal fluid leak, epistaxis, orbital complications, septal perforation, cellulitis or saddle nose deformity. No correlation was found between sinus surgery performed and need for revision surgery (CR or ESS) or postoperative infections. However, the time to patient reported resolution of postoperative nasal swelling was significantly higher in patients undergoing concurrent ESS/CR compared to CR only (dorsal swelling: 9.62 +/- 6.18 (ESS/CR) vs. 5.85 +/- 1.95 (CR) weeks, P = .0469; nasal tip swelling: 19.31 +/- 13.02 (ESS/CR) vs. 10.38 +/- 2.96 (CR) weeks, P = .0240, unpaired t test). The same relation held true for doctor noted postoperative edema

    Objective To verify the reliability and clinical feasibility of a self-developed navigation system based on an augmented reality technique for endoscopic sinus and skull base surgery. Materials and Methods In this study we performed a head phantom and cadaver experiment to determine the display effect and accuracy of our navigational system. We compared cadaver head-based simulated operations, the target registration error, operation time, and National Aeronautics and Space Administration Task Load Index scores of our navigation system to conventional navigation systems. Results The navigation system developed in this study has a novel display mode capable of fusing endoscopic images to three-dimensional (3-D) virtual images. In the cadaver head experiment, the target registration error was 1.28 ± 0.45 mm, which met the accepted standards of a navigation system used for nasal endoscopic surgery. Compared with conventional navigation systems, the new system was more effective in terms of operation time and the mental workload of surgeons, which is especially important for less experienced surgeons. Conclusion The self-developed augmented reality navigation system for endoscopic sinus and skull base surgery appears to have advantages that outweigh those of conventional navigation systems. We conclude that this navigational system will provide rhinologists with more intuitive and more detailed imaging information, thus reducing the judgment time and mental workload of surgeons when performing complex sinus and skull base surgeries. Ultimately, this new navigational system has potential to increase the quality of surgeries. In addition, the augmented reality navigational system could be of interest to junior doctors being trained in endoscopic techniques because it could speed up their learning. However, it should be noted that the navigation system serves as an adjunct to a surgeon’s skills and knowledge, not as a substitute. PMID:26757365

    Establish the feasibility of a predictive validity study in sinus surgery simulation training and demonstrate the effectiveness of the Endoscopic Sinus Surgery Simulator (ES3) as a training device. Prospective, multi-institutional controlled trial. Four tertiary academic centers with accredited otolaryngology-head and neck surgery residency programs. Twelve ES3-trained novice residents were compared with 13 control novice residents. Subjects were assessed on the performance of basic sinus surgery tasks. Their first in vivo procedure was video recorded and submitted to a blinded panel of independent experts after the panel established a minimum inter-rater reliability of 80 percent. The recordings were reviewed by using a standardized computer-assisted method and customized metrics. Results were analyzed with the Mann-Whitney U test. Internal rater consistency was verified with Pearson moment correlation. Completion time was significantly shorter in the experimental group (injection P = 0.003, dissection P manipulation (P = 0.011), and made fewer technical mistakes during the injection task (P = 0.048) compared with the control group. The raters' post hoc internal consistency was deemed adequate (r > 0.5 between serial measurements). The validity of the ES3 as an effective surgical trainer was verified in multiple instances, including those not depending on subjective rater evaluations. The ES3 is one of the few virtual reality simulators with a comprehensive validation record. Advanced simulation technologies need more rapid implementation in otolaryngology training, as they present noteworthy potential for high-quality surgical education while meeting the necessity of patient safety.

    It is recognized that stereotactic anatomical localization (SAL) is a useful tool in endoscopic sinus surgery (ESS), but it may be most beneficial for complex rather than routine sinus procedures. This review sought to determine the safety and efficacy of SAL in complex indications for ESS. PubMed, EMBASE, Centre for Reviews and Dissemination, and the Cochrane Library were searched from inception up to April 4, 2014. English studies comparing ESS with and without SAL in complex cases were included. Complex surgery included revision surgery, inverted papilloma, extensive sinus disease, or biopsy of tumors that are not exophytic. Safety outcomes included total, major, minor, orbital, dural, and major hemorrhage complications. Efficacy outcomes included operation completion, revision surgery, and patient-reported outcomes. Meta-analysis generated fixed-effects Mantel-Haenszel odds ratios (OR) and confidence intervals (CI). A total of 2,381 studies were identified, of which nine met the inclusion criteria. Meta-analyses indicated a reduction in the likelihood of total (OR = 0.58; 95% CI, 0.37-0.92), major (OR = 0.36; 95% CI, 0.18-0.75), and orbital complications (OR = 0.38; 95% CI, 0.17-0.83). There was no demonstrated benefit of SAL at reducing revision surgery (OR = 0.64; 95% CI, 0.38-1.08), major hemorrhage (OR = 0.77; 95% CI, 0.29-2.06), or minor complications (OR = 0.85; 95% CI, 0.48-1.50). Due to the rare outcomes under investigation, the included primary studies largely lacked the power to identify a statistically meaningful effect of SAL in ESS. However, meta-analyses of primary studies demonstrated a decreased likelihood of total, major, and orbital complications in complex ESS with the use of SAL. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

  14. The European positional paper on rhinosinusitis and nasal polyps: has the introduction of guidance on the management of sinus disease affected uptake of surgery and acute admissions for sinusitis?

    Rhinosinusitis is a common condition with adults experiencing 2-5 episodes per year. The European Positional Paper on Rhinosinusitis and Nasal Polyps (EP3OS) published in 2005 and updated in 2007 provided evidence-based guidelines on the management of sinus disease promoting a conservative approach to treatment. This study examines the effect of EP3OS on sinus surgery uptake and acute admissions for sinusitis in England and Wales. A retrospective study using the national electronic health databases of England (Hospital Episodes Statistics, HES online) and Wales (Patient Episodes Database of Wales, PEDW) was undertaken from 2000 to 2010 using the OPCS-4 codes E12-E17 (sinus surgery) and ICD10 code J01 (acute admission for sinusitis). Data were analysed for effect following the introduction of the EP3OS in 2005 using linear regression and Chi squared analysis. 116,370 sinus procedures and 10,916 acute admissions for sinusitis were made during the study period. No significant decrease in sinus surgery procedures occurred following the introduction of the EP3OS as may have been expected (p > 0.05), although subgroup analysis suggested a significant increase in Wales (p introduction of EP3OS (p 0.05). The EP3OS appears to have had little impact on the rates of sinus surgery but more conservative approaches to managing of sinus disease may have led to an increase in acute admissions. Further research is required to investigate whether changes in practice were adopted.

    To evaluate the feasibility of a unique prototype foot-controlled robotic-enabled endoscope holder (FREE) in functional endoscopic sinus surgery. Cadaveric study. Using human cadavers, we investigated the feasibility, advantages, and disadvantages of the robotic endoscope holder in performing endoscopic sinus surgery with two hands in five cadaver heads, mimicking a single nostril three-handed technique. The FREE robot is relatively easy to use. Setup was quick, taking less than 3 minutes from docking the robot at the head of the bed to visualizing the middle meatus. The unit is also relatively small, takes up little space, and currently has four degrees of freedom. The learning curve for using the foot control was short. The use of both hands was not hindered by the presence of the endoscope in the nasal cavity. The tremor filtration also aided in the smooth movement of the endoscope, with minimal collisions. The FREE endoscope holder in an ex-vivo cadaver test corroborated the feasibility of the robotic prototype, which allows for a two-handed approach to surgery equal to a single nostril three-handed technique without the holder that may reduce operating time. Further studies will be needed to evaluate its safety profile and use in other areas of endoscopic surgery. NA.

    Background Recent investigation has demonstrated that approximately 75% of patients with medically refractory chronic rhinosinusitis (CRS) report abnormal sleep quality, with strong correlation between worse sleep quality and more severe CRS disease severity. It remains unknown whether the treatment effect of endoscopic sinus surgery (ESS) for CRS results in appreciable sleep quality improvements. Methods Adult patients (aged ≥18 years) with a current diagnosis of recalcitrant chronic rhinosinusitis (CRS), who voluntarily elected ESS as the next treatment modality (n=301), were prospectively evaluated within four academic, tertiary care centers using treatment outcome instruments: the Rhinosinusitis Disability Index, the 22-item Sinonasal Outcome Test, the 2-item Patient Health Questionnaire, and the Pittsburgh Sleep Quality Index (PSQI) both before and after ESS. Results 72% of patients with CRS were found to have poor sleep (>5) at baseline with a mean global PSQI score of 9.4(4.6). Surgery improved overall mean global PSQI scores (2.2 points), and all 7 subdomain scores of the PSQI. Similarly, the odds of good sleep quality (PSQI ≤5) in patients treated with sinus surgery increased significantly (OR: 5.94, 95% CI: 3.06, 11.53; p<0.001). Stepwise multivariate linear regression found that ASA intolerance (β= −1.94(0.93); 95% CI: −3.77, −0.11; p=0.038), history of prior sinus surgery (β=1.10(0.54); 95% CI: 0.03, 2.16; p=0.044), and frontal sinusotomy (β= −1.03(0.62); 95% CI: −2.26, 0.20; p=0.099) were found to significantly associate with improvement in PSQI sleep scores. Conclusions Among patients with CRS, reduced sleep quality, poor disease-specific quality of life, and greater disease severity were improved following ESS. PMID:25079334

    Endoscopic sinus surgery (ESS) is a common procedure preferably done with an anesthetic technique ensuring effective postoperative analgesia while speeding discharge home. Although anesthesia administered locally in conjunction with vasoconstricting agents is known to minimize intraoperative bleeding, its usefulness in providing postoperative analgesia has not been well characterized. The results supporting the use of regional anesthesia for sinus surgery have also been limited. Using a randomized, double-blinded and placebo-controlled design, we evaluated recovery times, opioid consumption, and nausea and vomiting after ESS when patients were randomized to either general anesthesia (GA) alone or with regional blockade. Subjects were 70 adults scheduled for sinus surgery. All participants underwent propofol/remifentanil/nitrous oxide anesthesia and similar intraoperative care. Patients received either GA alone or with sphenopalatine ganglion (SPG) blocks in a double-masked study design. Independent observers recorded readiness for discharge, incidence of nausea/vomiting, and pain scores every 15 minutes until discharge. Overall opioid use in the recovery area was also a secondary end point. Twenty-four hours later, patients were called and asked to rate their pain and overall satisfaction with their pain control. Block group participants were considered ready for discharge after 45 minutes and discharged from the hospital ∼40 minutes sooner than GA group participants. The block group required less total fentanyl in the recovery room than did the GA group. The incidences of nausea and vomiting did not differ significantly. Data at 24 hours postoperatively did not differ significantly between groups but trended toward increased satisfaction in the block group. No lasting adverse events were observed. Regional anesthesia using targeted nerve blocks is effective in ESS. The combination of GA and SPG blockade appears to shorten hospital stay and reduce narcotic

    There is a need for controlled trials to guide the perioperative management of patients undergoing endoscopic sinus surgery (ESS). The authors performed a pilot multicenter trial to compare two types of saline delivery devices in this population. Patients were randomized to high volume saline irrigation with a squeeze bottle and low volume saline spray after ESS in patients with chronic rhinosinusitis (CRS). Surgeons were blinded to treatment, and one-month postoperative scores for sinonasal outcomes [Sinonasal Outcome Test-22 (SNOT-22)] scale, nasal and sinus symptom score (NSS), and perioperative sinus endoscopy (POSE) scale were compared with preoperative scores. Nine centers provided data for 86 patients. All three outcomes measures improved significantly for both groups. Saline spray: SNOT-22 48.8 versus. 23.7, treatment effect 25.1 (95% confidence interval [CI], 17.9-32.2), POSE 21.1 versus. 8.4, treatment effect 12.7 (95% CI, 9.2-16.1), and NSS 8.2 versus 5.0, treatment effect 3.1 (95% CI, 1.4-4.9) pre- and postoperatively, respectively (all p spray showed significant improvement in SNOT-22, POSE, and NSS scores at one-month postoperatively. Because the study was nonpowered, we cannot rule out a potential difference between the two treatment groups.

    Conclusion: An ideal surgical procedure for a pilonidal sinus should be one aiming at reducing hospital stay, minimizing tissue assault, promoting early work resumption, and preventing recurrence. The method described in this paper was found to be simple, safe, and feasible as day-care surgery. The technique of sinotomy with a good wound and surrounding skin care is an ideal approach with a high chance of cure. The patients returned to their routine within a short duration of time.

    With the advent of functional endoscopic sinus surgery (FESS) and coronal computed tomography (CT) imaging, considerable attention has been directed toward paranasal region anatomy. Detailed knowledge of anatomic variations in paranasal sinus region is critical for surgeons performing endoscopic sinus surgery as well as for the radiologist involved in the preoperative work-up. To be in the known anatomical variants with some accompanying pathologies, directly influence the success of diagnostic and therapeutic management of paranasal sinus diseases. A review of 512 (1024 sides) paranasal sinus tomographic scans was carried out to expose remarkable anatomic variations of this region. We used only coronal sections, but for some cases to clear exact diagnosis, additional axial CT scan, magnetic resonance imaging (MRI) and nasal endoscopy were also performed. In this pictorial essay, rates of remarkable anatomic variations in paranasal region were displayed. The images of some interesting cases were illustrated, such as the Onodi cell in which isolated mucocele caused loss of visual acuity, agger nasi cell, Haller's cell, uncinate bulla, giant superior concha bullosa, inferior concha bullosa, bilateral carotid artery protrusion into sphenoid sinus, maxillary sinus agenesis, bilateral secondary middle turbinate (SMT) and sphenomaxillary plate. The clinical importance of all these variations were discussed under the light of the literature. It was suggested that remarkable anatomic variations of paranasal region and their possible pathologic consequences should be well defined in order to improve success of management strategies, and to avoid potential complications of endoscopic sinus surgery. The radiologist must pay close attention to anatomical variations in the preoperative evaluation.

    Full Text Available BACKGROUND Allergic Fungal Sinusitis (AFS is a noninvasive type of fungal sinusitis, clinically and pathologically a unique entity of chronic rhinosinusitis. The aetiology, pathogenesis, and treatment of AFS are subject to controversy. In spite of aggressive endoscopic surgery, pre- and postoperative steroids and immunotherapy recurrence rates are high. Many additions are made to its original description and management since its early description in 1980. The aim of the present paper was to evaluate clinically. The response to high-dose itraconazole before endoscopic sinus surgery and in refractory postoperative patients. Related literature was reviewed in the light of the present study. MATERIALS AND METHODS A 2 year prospective study conducted on 68 AFS patients divided into two groups to clinically evaluate the results after using oral itraconazole preoperatively in one group and in refractory postoperative period in another. RESULTS The mean age of patients with typical AFS was 36±3.9 years. Patients with AFS with an average follow up of 21 months were included. Recurrence was 6/34 (17.64% in itraconazole group and revision FESS done in 3/34 (08.82%. Recurrence in patients without itraconazole was 16/34 (47.05% and refractory to conventional treatment, but responded to itraconazole in 14/16 (87.50%. Revision surgery required in 2/16 (12.50% after starting oral itraconazole. No side effects or reactions were observed in a total of 7920 doses administered. CONCLUSION Itraconazole is well tolerated by patients and effective in shrinking the polyposis preoperatively with low recurrence. Postoperative refractory AFS is amenable in (87.50% of patients avoiding repeat FESS. Overall, low recurrence rate and minimizing revision surgery when compared to patients treated without itraconazole was evident in the study.

    Virtual reality (VR) simulators provide an alternative to real patients for practicing surgical skills but require validation to ensure accuracy. Here, we validate the use of a virtual reality sinus surgery simulator with haptic feedback for training in Otorhinolaryngology - Head & Neck Surgery (OHNS). Participants were recruited from final-year medical students, interns, resident medical officers (RMOs), OHNS registrars and consultants. All participants completed an online questionnaire after performing four separate simulation tasks. These were then used to assess face, content and construct validity. anova with post hoc correlation was used for statistical analysis. The following groups were compared: (i) medical students/interns, (ii) RMOs, (iii) registrars and (iv) consultants. Face validity results had a statistically significant (P anatomy and as an introduction to ENT-specific procedures. The VR simulations have been validated for teaching sinus anatomy and nasendoscopy to medical students, interns and RMOs. However, they require further development before they can be regarded as a valid tool for more advanced surgical training. © 2015 John Wiley & Sons Ltd.

    Introduction Olfactory loss is a cardinal symptom of chronic rhinosinusitis (CRS) and affects 40–80% of patients. However, common sinus-specific quality-of-life (QOL) instruments include only single questions related to olfaction. Few studies have explored olfactory outcomes after surgery utilizing validated, olfaction-specific QOL questionnaires. Methods Patients with CRS were enrolled from 3 centers across North America into a prospective cohort study. Patients completed the short modified version of the Questionnaire of Olfactory Disorders (QOD-NS) and the 40-item Smell Identification Test (SIT-40) before and at least 6 months after endoscopic sinus surgery (ESS). Multivariate linear regression was used to determine whether specific demographic, comorbidity, or disease severity measures were independently associated with QOD scores at baseline or predicted change after surgery. Results A total of 121 patients, equally split between genders, were enrolled with an average age of 47.9 years (range: 18–80). Baseline total QOD-NS scores were significantly associated with SIT-40 scores, with a moderate strength of correlation (Rs=0.400; p<0.001). The average QOD-NS score improved after ESS (35.7±13.0 vs. 39.7±12.2; p=0.006). Allergy, polyps, and steroid dependent conditions were found to be independently associated with worse preoprerative QOD-NS scores, while septal deviation was associated with better QOD-NS scores. Baseline computed tomography (CT) scores were the only variable which significantly predicted change in QOD-NS after surgery. Conclusion Olfaction-specific QOL is worse in patients with polyps and comorbid allergy. Significant improvements in olfaction-specific QOL are seen after ESS, with the greatest gains seen in those with worse CT scores at baseline. PMID:26678351

    The purpose of this study is to review the literature to assess the incidence of maxillary sinus disease before sinus floor elevation surgery (SFE) as identified by cone-beam computerized tomography (CBCT). Only studies in which CBCT was performed in patients for dental implant placement in the past 10 years were considered. Eleven studies were identified. A total of 1792 patients were collected. All the studies reviewed reported on thickening of the sinus mucosa as a criterion for sinus disease with different threshold values. All studies reported mucosal thickening (MT) ranging between 25.5% and 93.1%. The mean incidence of MT was 54.99%. Two studies examined the correlation of MT with clinical symptoms. Three studies reported evaluation of the ostiomeatal complex (OMC). There is a high probability of detecting a certain degree of MT in patients referred for SFE. There is no consensus regarding the threshold values beyond which MT is considered pathological. Independently from the threshold values or the type of MT, the studies lack correlation with clinical data regarding patients' sinusitis-related history or symptoms. CBCT with a large field of view to evaluate the OMC is appropriate in patients scheduled for SFE. Future studies should include a systematic correlation with clinical symptoms and the possible presence of OMC obstruction. A clinical assessment that includes nasal endoscopy is indicated when MT and obstruction of the OMC are identified. Surgical correction of OMC obstruction seems to be appropriate to increase the success rate and to avoid possible complication after SFE.

    Introduction Synechiae are one of the most common unwanted outcomes after endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS). However, there has been scant investigation into the true significance of synechiae formation after ESS. The aim of this study was to evaluate the impact of synechiae formation on quality-of-life (QOL) outcomes after ESS in patients with CRS. Study Design Prospective, multi-institutional cohort. Methods Rhinosinusitis Disability Index (RSDI) and Chronic Sinusitis Survey (CSS) scores were measured in adult patients before and after undergoing ESS for CRS. Differences in QOL were evaluated between those who developed sinonasal synechiae and those who did not, controlling for demographic factors, medical comorbidities, and measures of disease severity at baseline. Results A total of 286 patients underwent ESS, with 55 (19.2%) developing synechiae in the follow-up period. Patients developing synechiae reported significantly less improvement on the RSDI total scores (13.5 vs. 21.4, p=0.008), RSDI physical subscores (5.3 vs. 8.3, p=0.007), RSDI emotional subscores (2.9 vs. 5.8, p=0.008), CSS total scores (14.5 vs. 21.2, p=0.093) and CSS symptom subscores (19.9 vs 30.3, p=0.069) compared to those who did not develop synechiae postoperatively. These differences persisted even after controlling for baseline differences in disease severity. Conclusions Synechiae of the sinonasal cavity commonly occurs following ESS, particularly in those undergoing revision surgeries. Although both groups improve, the degree of QOL improvement appears to be less in those who form postoperative synechaie after surgery compared to those who do not. PMID:23670876

    Early postoperative care following endoscopic sinus surgery (ESS) has been suggested to minimize avoidable complications and optimize long-term outcomes. Several postoperative care strategies have been proposed but a formal comprehensive evaluation of the evidence has never been performed. The purpose of this article is to provide an evidence-based approach to early postoperative care following ESS. A systematic review of the literature was performed and the Clinical Practice Guideline Manual, Conference on Guideline Standardization (COGS), and the Appraisal of Guidelines and Research Evaluation (AGREE) instrument recommendations were followed. Study inclusion criteria were: adult population >18 years old; chronic rhinosinusitis (CRS) based on published diagnostic criteria; ESS following failed medical therapy; primary study objective was to evaluate an ESS early postoperative care strategy; and clearly defined primary clinical end-point. This review identified and evaluated the literature on 7 early postoperative care strategies following ESS: saline irrigations, sinus cavity debridements, systemic steroids, topical steroids, oral antibiotics, topical decongestants, and drug-eluting spacers/stents. Based on the available evidence, use of nasal saline irrigation, sinus cavity debridement, and standard topical nasal steroid spray are recommended early postoperative care interventions. Postoperative antibiotic, systemic steroid, nonstandard topical nasal steroid solution, and/or drug-eluting spacers/stents are options in postoperative management. These evidence-based recommendations should not necessarily be applied to all postoperative patients and clinical judgment, in addition to evidence, is critical to determining the most appropriate care.

    The aim of the present study is to propose legal reform limiting surgeons' criminal liability in high-accuracy and high-risk surgery such as endoscopic sinus surgery (ESS). The study includes a review of the medical literature, focusing on identifying and examining reasons why ESS carries a very high risk of serious complications related to inaccurate surgical manoeuvers and reviewing British and Italian legal theory and case-law on medical negligence, especially with regard to Italian Law 189/2012 (so called "Balduzzi" Law). It was found that serious complications due to inaccurate surgical manoeuvers may occur in ESS regardless of the skill, experience and prudence/diligence of the surgeon. Subjectivity should be essential to medical negligence, especially regarding high-accuracy surgery. Italian Law 189/2012 represents a good basis for the limitation of criminal liability resulting from inaccurate manoeuvres in high-accuracy surgery such as ESS. It is concluded that ESS surgeons should be relieved of criminal liability in cases of simple/ordinary negligence where guidelines have been observed. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

    Virtual reality simulators provide an effective learning environment and are widely used. This study evaluated the Endoscopic Sinus Surgery Simulator (ES3; Lockheed Martin) as a tool for anatomic education. Two medical student groups (experimental, n = 8; control, n = 7) studied paranasal sinus anatomy using either the simulator or textbooks. Their knowledge was then tested on the identification of anatomic structures on a view of the nasal cavities. The mean scores were 9.4 +/- 0.5 and 5.1 +/- 3.0 out of 10 for the simulator and textbook groups, respectively (P = .009). Moreover, the simulator group completed the test in a significantly shorter time, 5.9 +/- 1.1 versus 8.3 +/- 2.0 minutes (P = .021). A survey asking the students to rate their respective study modality did not materialize significant differences. The ES3 can be an effective tool in teaching sinonasal anatomy. This study may help shape the future of anatomic education and the development of modern educational tools.

    The aim of this study was to assess the influence of spray cryotherapy on wound healing following endoscopic sinus surgery (ESS). A prospective, randomized, double-blinded, controlled trial. The study included 22 consecutive adult patients with chronic rhinosinusitis with and without polyps scheduled for bilateral ESS. At the end of the surgical procedure, patients were randomized to the distribution of spray cryotherapy in one middle meatus and saline contralaterally. Outcomes were only measured for endoscopy scores. Thus, postoperative healing and the amount of edema, crusting, secretions, and scarring were assessed using the validated Lund-Kennedy and Perioperative Sinus Endoscopy (POSE) scores. There were no baseline differences concerning POSE and Lund-Kennedy scores between the two groups. Nevertheless, a significant difference was recorded at one, 2, 4, 8, and 12 weeks in both POSE (P = .001, P = .012, P = .02, P = .006, P = .001) and Lund-Kennedy (P = .002, P = .005, P = .02, P = .02, P = .03) scores. These preliminary results reveal an improvement in postoperative scores, demonstrating enhanced healing following spray cryotherapy. However, without patient subjective outcomes, the study is limited. Additional studies with longer follow-up and larger samples are needed to describe the effects of cryotherapy on wound healing. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

Cinco pacientes com diagnóstico de osteoma de seio frontal foram operados entre 1995 e 1999. A idade média foi 38,4 anos (extremos de 12 a 55 anos, sendo 3 homens e 2 mulheres. O período de sintomatologia variou de 6 meses a 3 anos com média de 10,5 meses. Quatro pacientes apresentaram cefaléia. Um paciente apresentou epistaxe. Os exames complementares realizados foram: radiografia simples e tomografia computadorizada de seios paranasais com cortes axiais e coronais. Em dois pacientes o diâmetro do osteoma foi maior que 3 cm, e menor que 3 cm em três. A decisão da técnica cirúrgica entre coronal e supraciliar foi estética, reservando-se a abordagem supraciliar para um paciente com calvície, apesar do tumor ser volumoso com extensão para seio etmoidal. Nenhuma dificuldade técnica intra-operatória foi atribuída à escolha da abordagem. O óstio nasofrontal não foi obstruído no intra-operatório. O seguimento pós-operatório mínimo foi de dois anos. Em todos os casos a remoção foi total sem recidiva ou resíduos tumorais. Os sintomas clínicos, achados radiológicos e abordagens cirúrgicas são discutidos. Não ocorreram complicações pós-operatórias.Frontal sinus osteomas are 57% of all paranasal sinus osteomas, with an incidence of 00.1 to 3%. Surgical removal of the frontal sinus osteomas is done in symptomatic patients. Asymptomatic patients can be managed conservatively or submitted to surgery in spite of its location or extension. Five patients having the diagnosis of frontal sinus osteoma were operated on between 1995 and 1999. Medium age was 38.4 years (from 12

    The objective was to quantify bone formation within autogenous bone grafts and autogenous bone grafts in combination with platelet-rich plasma obtained either from apheresis or centrifugation using computed tomography. This prospective, double-blind study was conducted in 34 male and female adult patients (mean age of 28 years and 8 months), with either unilateral or bilateral pneumatization of the maxillary sinuses, requiring bone graft for dental implant. All patients were submitted to computed tomography examinations prior and six months after sinus lift surgery. Fifty-three maxillary sinuses were operated and divided into three distinct groups: autogenous bone graft, autogenous bone graft in combination with platelet-rich plasma obtained by centrifugation, and autogenous bone graft in combination with platelet-rich plasma obtained by apheresis. The results showed that computed tomography demonstrated bone growth in height and width between the initial and the follow-up computed tomography scans in all three groups. However, no statistical difference was found either for bone height or width. It was concluded that clinical evidence demonstrates the effectiveness of autogenous bone grafts, particularly when used in combination with bone growth factors such as platelet-rich plasma, which allow prosthetic and functional restoration of maxillofacial structures through fixation of dental implants.

    Endoscopic sinus surgery poses unique training challenges due to complex and variable anatomy, and the risk of major complications. We sought to create and provide validity evidence for a novel 3D-printed simulator of the nose and paranasal sinuses. Sinonasal computed tomography (CT) images of a patient were imported into 3D visualization software. Segmentation of bony and soft tissue structures was then performed. The model was printed using simulated bone and soft tissue materials. Rhinologists and otolaryngology residents completed 6 prespecified tasks including maxillary antrostomy and frontal recess dissection on the simulator. Participants evaluated the model using survey ratings based on a 5-point Likert scale. The average time to complete each task was calculated. Descriptive analysis was used to evaluate ratings, and thematic analysis was done for qualitative questions. A total of 20 participants (10 rhinologists and 10 otolaryngology residents) tested the model and answered the survey. Overall the participants felt that the simulator would be useful as a training/educational tool (4.6/5), and that it should be integrated as part of the rhinology training curriculum (4.5/5). The following responses were obtained: visual appearance 4.25/5; realism of materials 3.8/5; and surgical experience 3.9/5. The average time to complete each task was lower for the rhinologist group than for the residents. We describe the development and validation of a novel 3D-printed model for the training of endoscopic sinus surgery skills. Although participants found the simulator to be a useful training and educational tool, further model development could improve the outcome. © 2017 ARS-AAOA, LLC.

    Full Text Available BACKGROUND AND OBJECTIVES: It is crucial to decrease bleeding during functional endoscopic sinus surgery. Our primary goal was to investigate the effects of magnesium sulfate and dexmedetomidine used for controlled hypotension on the visibility of the surgical site. METHODS: 60 patients aged between 18 and 65 years were enrolled. In the magnesium sulfate group (Group M, patients were administered 40 mg/kg magnesium sulfate in 100 mL saline solution over 10 min as the intravenous loading dose 10 min before induction, with a subsequent 10-15 µg/kg/h infusion during surgery. In the dexmedetomidine group (Group D, patients were administered 1 µg/kg dexmedetomidine in 100 mL saline solution as the loading dose 10 min before surgery and 0.5-1 µg/kg/h dexmedetomidine during surgery. Deliberate hypotension was defined as a mean arterial pressure of 60-70 mmHg. RESULTS: Bleeding score was significantly decreased in Group D (p = 0.002. Mean arterial pressure values were significantly decreased in Group D compared to that in Group M, except for the initial stage, after induction and 5 min after intubation (p < 0.05. The number of patients who required nitroglycerine was significantly lower in Group D (p = 0.01 and surgeon satisfaction was significantly increased in the same group (p = 0.001. Aldrete recovery score ≥9 duration was significantly shorter in Group D (p = 0.001. There was no difference between the two groups in terms of recovery room verbal numerical rating scale. CONCLUSIONS: Dexmedetomidine can provide more effective controlled hypotension and thus contribute to improved visibility of the surgical site.

    Full Text Available Objective  To explore the feasibility of dexmedetomidine as an adjuvant of sevoflurane for controlled hypotension in endoscopic sinus surgery. Methods  Forty-eight patients (ASA Ⅰor Ⅱ scheduled for endoscopic sinus surgery were randomly assigned into two groups (n=24: control group (group I and dexmedetomidine group (group Ⅱ. In both groups, intravenous injection of midazolam, propofol, fentanyl, and atracurium besilate was given to induce anesthesia, and propofol, fentanyl, atracurium besilate, together with sevoflurane inhalation were used to maintain anesthesia. The radial artery was cannulated to monitor the invasive mean arterial pressure (MAP. Controlled hypotension was induced by adjusting the sevoflurane concentration in group Ⅰ. In group Ⅱ, within 15min to 30min before the induction of anesthesia, dexmedetomidine was administered in a dose of 0.8μg/kg via intravenous infusion pump, then maintained at 0.4μg/(kg·h. Sevoflurane concentration was adjusted to maintain the target blood pressure at the beginning of surgery. The MAP was maintained at 65-75mmHg up to the end of operation. Meanwhile, the heart rate (HR, MAP, epinephrine (E, and norepinephrine (NE concentrations were recorded at the time of induction of anesthesia (T0, beginning of controlled hypotension (T1, 30min after controlled hypotension (T2, and at the time when extubation was performed (T3. Blood gas analysis and determination of lactic acid concentration were conducted using the blood drawn from the radial artery during the operation. The surgical field quality was assessed based on Fromme scores of surgical field quality (SSFQ. Meanwhile, the dose of sevoflurane, propofol, and fentanyl, MAP, the recovery time of anesthesia, and the incidence rate of untoward effects were recorded. Results  The doses of propofol, fentanyl and sevoflurane, and MAC value in group Ⅱwas significantly diminished compared with group Ⅰ(P<0.01. In addition, the surgical

    The main purpose was to evaluate the recurrence rate after surgery for antrochoanal polyps (ACPs) in children; secondly, we have analyzed the rate of recurrence for different types of surgery and the risk factors involved. We performed a systematic review searching PubMed and MEDLINE databases including English-language published studies from June 1989 to October 2017 regarding surgical treatment of ACPs in children. We included thirteen studies, eight were retrospective and five prospective, with 285 participants, the mean rate of recurrence after ACPs surgery was 15.0% (95% CI:11.0-20.0). Functional endoscopic sinus surgery (FESS) was the main type of surgery used for primary cases (75.4%) followed by the combined approach i.e. FESS with a transcanine sinusoscopy or mini Caldwell-Luc (14%), the Caldwell-Luc (CWL) (8%) and simple polypectomy (SP) (2.8%). Our analysis has demonstrated a significant reduction of recurrences using the combined approach 0% (95% CI: 0.0-8.0) compared with FESS 17.7% (95% CI: 12.8-23.4) or SP 50% (95% CI:15.7-84.3) (p  .05). The analysis of the possible risk factors involved in recurrences are inconclusive. Recurrences of ACPs in children are still high. The endoscopic sinus surgery is considered the first choice for primary treatment, whilst the external approach may be a valid option in case of recurrence. It seems that the combined approach could reduce recurrence rates in selected patients that cannot be completely managed with endoscopy. Copyright © 2018 Elsevier B.V. All rights reserved.

    We investigated the impact and the predictive value of sinus rhythm at 12 months (SR12) on subscales of three different HrQoL questionnaires: SF-36., EuroQoL and MFI 20. Data of 125 cardiac surgery patients with pre-operative AF from our previous randomized trial were used. Based on their rhythm outcome patients were divided in two groups: SR12 or AF at 12 months follow up (non-SR12). All questionnaires were self-administered pre-operatively and at 3 months, 6 months and 12 months after surgery. Synus rhytm at 12 months was predictive of improvement of SF36- mental score (MS, p = 0.021), Euro-QoL-MS (p = 0.009), VAS (p = 0.006), and MFI 20-MS (p = 0.009).

    Full Text Available Abstract Background Sinonasal inverted papilloma is a locally aggressive tumor arising from the Schneiderian membrane which lines the nasal cavity and paranasal sinuses. Aggressive surgical approaches, such as lateral rhinotomy, were used until recently for complete removal of the inverted papilloma. Currently, endoscopic resection is the gold standard in the treatment of inverted papilloma. However, there are situations that justify an open approach. For example there are studies that report a higher postoperative recurrence rate after endonasal endoscopic resection, particularly in the treatment of recurrent diseases. While endoscopic resection performed by an experienced surgeon is definitely a minimally invasive therapy, an open approach is not necessarily associated with functional and aesthetic disadvantages. This case report describes the treatment of inverted papilloma by an open approach. This has been described before but the new gold standard of endoscopic resection has to be taken into account before any treatment decision is made nowadays. Case presentation Contrast-enhanced magnetic resonance imaging of the head and neck area was indicated in a 72-year-old white German man who presented with suspected squamous cell carcinoma of his lower lip. Magnetic resonance imaging additionally revealed a 3×2 cm2 polycyclic arranged mucosal thickening with cystic and solid contrast affine shares at the antral laterocaudal area of his right maxillary sinus, extending from his right lateral nasal wall to his maxillary sinus floor. He received antral polypectomy with medial maxillectomy via a unilateral LeFort I osteotomy approach. His pterygoid plate was preserved. A histological examination demonstrated a tumor composed of hyperplastic squamous epithelium protruding into the stroma (surface epithelial cells grew downward into the underlying supportive tissue, thus producing a grossly convoluted cerebriform appearance. Two weeks later, the

    Endoscopic sinus surgery (ESS) is the treatment of choice for patients with chronic rhinosinusitis (CRS) refractory to medical therapy. ESS successfully reduces most symptoms of CRS, but its effect on olfaction is always uncertain. The aim of this study was to assess the influence of sinus surgery on olfaction and to analyze the predictors of olfactory function before and after ESS in the context of a literature review. The study group comprised of 153 patients with CRS refractory to medical treatment. The patients evaluated their olfactory function before ESS, 3-6 months after ESS (121 individuals) and 12 months after ESS (58 individuals). Statistical analysis concerned the postoperative olfactory improvement as well as the influence of various predictors on the impairment of smell before and after surgery. Olfactory dysfunction was significantly reduced after ESS. The smell impairment before and after surgery depended on different predictors. Patients with severe preoperative olfactory dysfunction and extensive pathological changes in the nose and sinuses, including nasal polyps, reported most pronounced improvement after ESS. However, severely hyposmic subjects with nasal polyposis, asthma or aspirin intolerance as well as older patients reported worse postoperative smell scores.

    Objective: To compare the effect of preoperative oral steroids (prednisolone) on perioperative and postoperative hemorrhage in patients undergoing functional endoscopic sinus surgery for chronic sinusitis with those who do not receive steroids. Design: Randomized controlled trials. Place and duration of study: This study was conducted in ENT Department Shaikh Khalifa Bin Zayed Al Nahyan Hospital (CMH) Muzaffarabad from 15th Jan 2010 to 20th Feb 2011. Patients and Methods: After getting informed consent total of 60 patients who fulfilled the inclusion criteria were selected and functional endoscopic sinus surgery was carried out. They were divided into two groups of 30 each by using random number tables. Group A received prednisolone in a dose of 01 mg/kg body weight for 01 week prior to surgery (last day of dose being the day prior to operative day) while group B (control group) did not receive any steroid. Results: There was a significant difference in both perioperative and postoperative hemorrhage with better control rates in group A. Conclusion: Prednisolone given preoperatively significantly reduces the morbidity that is perioperative and postoperative hemorrhage thus early recovery to normal life style in patients undergoing functional endoscopic sinus surgery for chronic sinusitis.

    Full Text Available Purpose. We present a case of a bilateral postoperative maxillary cyst (PMC and discuss this with a systemic review. Case Report and Literature Review. A 68-year-old female with pain and swelling on the right side of the face. MRI and CT showed a cystic tumors of the right and left maxillary sinus. Radical maxillary surgery via a Caldwell-Luc procedure had been performed 55 years ago and bilateral PMC was diagnosed. The PubMed database was searched for PMC within the last 30 years. Results. Together with the current case, we found 23 reports including 284 patients describing PMC. It was diagnosed at a mean time of 22 years after causal surgery at a mean age of 47 years. Initial symptoms were mostly pain with or without swelling. The main radiological sign was a unilocular radiolucency with a slight preference for the left side. Discussion. PMC is a long-term complication that can occur after maxillary sinus surgery and a second surgical approach is required in order to stop cystic expansion. Therefore, patients’ informed consent on this complication as well as a prolonged follow-up is recommended. Simple paranasal ultrasound or paranasal sinus plain radiography may lead to an earlier detection reducing interventional morbidity.

    The primary objective of this pilot study was to define the change in productivity costs following endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS). Secondary objectives were to identify CRS-related characteristics that may influence the degree of productivity improvement after ESS. Prospective, multi-institutional, observational cohort study. The human capital approach was used to define productivity costs. Annual absenteeism, presenteeism, and lost leisure time were quantified to define annual lost productive time (LPT). LPT was monetized using the annual daily wage rates obtained from the 2012 US Census and the 2013 US Department of Labor statistics. Twenty-seven patients with refractory CRS who underwent ESS were followed for a mean of 15 months (range, 8-25 months). Following ESS, there were improvements in annual absenteeism (22 days reduced to 3 days), annual presenteeism (41 days reduced to 19 days), and annual household days lost (12 days reduced to 6 days). Overall, the preoperative productivity costs were reduced after ESS ($9,190 vs. $3,373, respectively; P productivity is negatively impacted by the presence of CRS. The outcomes from this study provide the first insights into the reduced productivity costs associated with receiving ESS for refractory CRS. Future studies with larger sample sizes will need to validate the results from this pilot study. 2c Laryngoscope, 126:570-574, 2016. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    Due to proximity to critical structures, the need for spatial awareness during endoscopic sinus surgery (ESS) is essential. We have developed an augmented, real-time image-guided surgery (ART-IGS) system that provides live navigational data and proximity alerts to the operating surgeon during ablation. We wished to test the hypothesis that task workload would be reduced when using this technology. A trial involved 8 otolaryngology residents and fellows performing ESS on cadaveric specimens; 1 side in a conventional method (control) and 1 side with ART-IGS. After computed tomography scanning, anatomical contouring, and registration of the head, a three-dimensional (3D) virtual endoscopic view, ablative tool tracking, and proximity alerts were enabled. Each subject completed ESS tasks and rated their workload during and after the exercise using the National Aeronautics and Space Administration (NASA) Task Load Index (TLX). A questionnaire and open feedback interview were completed after the procedure. There was a significant reduction in mental demand, temporal demand, effort, and frustration when using the ART-IGS system in comparison to the control (p < 0.02). Perceived performance was increased (p = 0.02). Most subjects agreed that the system was sufficiently accurate, caused minimal interruption, and increased confidence. Optical tracking line-of-sight issues were frequently cited as the main limitation early in the study; however, this was largely resolved. ART-IGS reduces task workload for trainees performing ESS. Live navigation and alert zones may be a valuable intraoperative teaching aid. Copyright © 2012 American Rhinologic Society-American Academy of Otolaryngic Allergy, LLC.

    Full Text Available The preemptive analgesic efficacy and adverse effects of preoperatively administered piroxicam-β-cyclodextrin for post-endoscopic sinus surgery pain was determined in a prospective, double-blind, randomized, clinical study. Seventy-five American Society of Anesthesiologists status I-II patients, aged 18-65 years, were divided into three groups with similar demographic characteristics: group 1 received 20 mg piroxicam-β-cyclodextrin, group 2 received 40 mg piroxicam-β-cyclodextrin and group 3 received placebo orally before induction of general anesthesia. A blinded observer recorded the incidence and severity of pain at admission to the post-anesthesia care unit (PACU, at 15, 30, and 45 min in the PACU, and 1, 2, 4, 6, and 24 h postoperatively. All patients received patient-controlled morphine analgesia during the postoperative period and consumption was recorded for 24 h. During the PACU period, mean visual analogue scale values were significantly lower in groups 1 and 2 compared to group 3 (P < 0.05. During the postoperative period, morphine consumption was 3.03 ± 2.54, 2.7 ± 2.8, and 5.56 ± 3.12 mg for each group, respectively (P < 0.05. As a side effect, bleeding was observed in groups 1 and 3, nausea and vomiting in all groups, and edema only in group 3. However, no significant differences were detected in any of the parameters analyzed, which also included epigastric pain, constipation/diarrhea and headache. Similar hematological test results were obtained for all groups. Preemptive administration of piroxicam-β-cyclodextrin effectively reduced analgesic consumption, and 40 mg of the drug was more effective than 20 mg piroxicam-β-cyclodextrin without side effects during the postoperative period.

    Background Both obesity and chronic rhinosinusitis (CRS) are characterized by inflammation. Furthermore, both disease processes are independently associated with decreases in quality-of-life (QOL). We sought to investigate the role of comorbid obesity in QOL outcomes in CRS patients undergoing endoscopic sinus surgery (ESS). Methods Adult patients with medically refractory CRS (n=241) were prospectively enrolled into a multi-institutional treatment outcomes investigation. Body mass index (BMI) calculations were used to differentiate patient weight groups (normal weight: 18.5–24.9, overweight: 25.0–29.9; and obese: ≥30.0). Preoperative and postoperative QOL (Rhinosinusitis Disability Index (RSDI) and the 22-item Sinonasal Outcome Test (SNOT-22)) were evaluated compared across BMI groups and obesity subclasses. Results The prevalence of comorbid obesity was 41% (n=99). Higher prevalence of comorbid disease was found across increasing BMI groups including diabetes mellitus, asthma, and depression. No significant differences were found in mean preoperative QOL measures between any BMI groups. Significant improvement between preoperative and postoperative QOL mean scores (p≤0.050) was found for all BMI groups. Despite no significant difference in mean QOL improvement between BMI groups (p≥0.142), overweight and obese patients reported reduced relative mean percentage (%) improvement compared to normal weight participants on the RSDI total score (33% and 37% vs. 55%, respectively) and SNOT-22 total score (29% and 40% vs. 48%, respectively). Conclusions Patients with comorbid obesity experience significant improvement in average QOL gains following ESS though the percentage of relative improvement in QOL may be decreased in patients with comorbid obesity and CRS as compared to those without.

    The optimal treatment of advanced maxillary sinus cancer has been challenging for several decades. Intra-arterial chemotherapy (IAC) for head and neck cancer has been controversial. We have analyzed the long-term outcome of neoadjuvant IAC followed by radiation therapy (RT) and surgery. Twenty-seven patients with advanced maxillary sinus cancer were treated between 1989 and 2002. Five-fluorouracil (5-FU, 500 mg/m2) was infused intra-arterially, and followed by RT (total 50.4 Gy/28 fractions). A planned surgery was performed 3 to 4 weeks after completion of IAC and RT. At a median follow-up of 77 months (range, 12 to 169 months), the 5-year rates of overall survival in all patients were 63%. The 5-year rates of overall survival of stage T3/T4 patients were 70.0% and 58.8%, respectively. Seven of fourteen patients with disease recurrence had a local recurrence alone. The 5-year actuarial local control rates in patients with stage T3/T4, and in all patients were 20.0%, 32.3%, and 27.4%, respectively. Overall response rate after the completion of IAC and RT was 70.3%. During the follow-up, seven patients (25.9%) showed mild to moderate late complications. The tumor extent (i.e., the involvement of either orbit and/or base of skull) appeared to be related with local recurrence. Neoadjuvant IAC with 5-FU followed by RT and surgery may be effective to improve local tumor control in the patients with advanced maxillary sinus cancer. However, local failure was still the major cause of death. Further investigations are required to determine the optimal treatment schedule, radiotherapy techniques and chemotherapy regimens.

    implant. All patients were submitted to computed tomography examinations prior and six months after sinus lift surgery. Fifty-three maxillary sinuses were operated and divided into three distinct groups: autogenous bone graft, autogenous bone graft in combination with platelet-rich plasma obtained by centrifugation, and autogenous bone graft in combination with platelet-rich plasma obtained by aphaeresis. RESULTS: Computed tomography demonstrated bone growth in height and width between the initial and the follow-up computed tomography scans in all three groups. However, no statistical difference was found either for bone height or width. CONCLUSION: Clinical evidence demonstrates the effectiveness of autogenous bone grafts, particularly when used in combination with bone growth factors such as platelet-rich plasma, which allow prosthetic and functional restoration of maxillofacial structures through fixation of dental implants.

    The current German S3 guidelines recommend radical excision for pilonidal sinus disease. Furthermore, the Karydakis operation and the plastic surgery procedure according to Limberg are also recommended. Contrary to the S2 guidelines of 2008, these two plastic surgery procedures for coverage are recommended for the treatment of the first-time manifestation of this disease. Most studies on the classical Limberg plastic surgical procedure are comparative in nature and describe a simultaneous intervention from which patients with an abscess are excluded. The aim of this present study was to analyze the results of a sequential procedure including primary excision followed by a Limberg plastic surgery procedure for the treatment of acute abscesses and chronic pilonidal sinus disease. From July 2010 to June 2013 a total of 50 patients with pilonidal sinus disease were treated at the University Hospital Jena with an initial radical excision. In accordance with the Association of the Scientific Medical Societies in Germany (AWMF) guidelines which were valid during that time, patients were offered plastic surgery coverage for recurrence prophylaxis and in cases of recurrence a Limberg plastic surgery procedure was recommended. Of the 50 patients 22 opted for a Limberg plastic surgery procedure during the interval. The mean follow-up after the Limberg plastic surgery procedure was 20.1 months (range 2-36 months). During the follow-up period, there were no recurrences (0 %) but four major complications (18.2 %) and one minor complication (4.5 %) were observed. This concept can be applied in cases of acute abscess formation and in chronic pilonidal sinus disease. The patient's decision with respect to a Limberg plastic surgery procedure for recurrence prophylaxis does not have to be made immediately. In addition, the Limberg plastic surgery procedure is performed in an infection-free stage. The second inpatient stay, second surgical procedure and prolonged time off work are a

    The detailed radiological study of the anatomy of the nasal cavities and paranasal sinus is essential prior to endoscopic sinus surgery since, on the one hand, it discloses the extent of the disease and, on the other hand, it aids in the detection of the numerous anatomic variants, some of which are of great interest to the endoscopic as the lack of preoperative knowledge of them may increase the risk of complications. the objective of the present report is to review these variants, stressing those that may be associated with a greater surgical risk. Although coronal computed tomography is the technique of choice for pre endoscopy examination, certain structures and anatomic variants are better viewed in axial images. These exceptions include anterior and posterior walls of the frontal sinuses, the anatomic relationships between posterior ethmoid complex and the sphenoid sinus, the relationships between the sphenoid sinus and the optic nerve, and the detection of Onodi cells. Thus, we recommend that the radiological examination include both coronal and axial images. (Author) 16 refs.

    Objective: To evaluate the olfactory fossae depth according to the Keros' classification and determine the incidence and degree of asymmetry in the height and contour of the ethmoid roof. Materials and methods: Retrospective analysis of 200 coronal computed tomography studies of paranasal sinuses performed in the period between August and December, 2006. Results: According to the Keros' classification, olfactory fossae type II was most frequently found in 73.3% of cases followed by type I in 26.3% and type III in 0.5% of cases. Asymmetry in the ethmoid roof height was found in 12% of cases (24 computed tomography studies), and contour asymmetry was found in 48.5% (97 computed tomography studies), with flattening of the ethmoid roof on one of the sides. Conclusion: As regards the olfactory fossae depth, the Keros' type II was most frequently found. In most of cases, the ethmoid roof asymmetry was related to angulation of the lateral lamella of the cribriform plate. (author)

    To evaluate the impact of FESS in children with chronic rhinosinusitis with nasal polyps, regarding their overall postoperative quality-of-life (QoL) and constituent QoL domains. Potential differences between cystic fibrosis (CF) sufferers and non-sufferers, or cases with recurrent sinonasal polyposis versus single-operations were also explored. 39 children were studied. The mean patient age was 10.9 years; four children suffered from cystic fibrosis. The children (or parents) completed the Glasgow Benefit Inventory for Children (GCBI) at least six months after their operation. The Mann-Whitney test compared the GCBI scores between non- and CF sufferers, as well as children with and without recurrent polyposis. The median overall QoL score was 98. There were no statistically significant differences between CF sufferers and non-sufferers regarding their overall QoL, or the respective individual QoL domains, apart from their physical postoperative activity (p = 0.04). Twelve children demonstrated recurrent polyposis (30.7%); among them three were cystic fibrosis sufferers. No statistically significant differences were identified in the overall QoL score, or individual GCBI subscale scores between children with recurrent polyposis versus single-operations. Children with recurrent polyposis but not CF performed better regarding their overall QoL (p = 0.021) and medical status (p = 0.015), compared to their CF counterparts. FESS performed for chronic rhinosinusitis with nasal polyps in children is associated with improved postoperative QoL, irrespective of the presence of CF (although the latter needs to be confirmed in larger patient cohorts). The absence of appreciable differences in the overall QoL, or its constituent domains, between single and re-operated children, indicate that the positive effect of FESS outweighed the burden of re-operation. Appropriate preoperative informed consent in cases of recurrent sinonasal polyposis necessitates acknowledging worse

    The aim of this study was to assess the efficacy and safety of macroporous biphasic calcium phosphate (MBCP())/fibrin grafts (TricOs((R)))/(Tisseel((R))) for sinus lift augmentation in sheep. Autologous bone grafts were used as a positive control, and dental implants were placed to assess the efficiency of the composite. A total of 12 adult sheep (24 maxillary sinuses) were randomized to receive sinus lift augmentation with MBCP()/fibrin grafts obtained by either simultaneous or sequential addition of thrombin and fibrinogen to MBCP(), or autologous bone grafts. Six months post-sinus lift surgery, dental implants were placed. At 6 months post-sinus lift and 3 months after dental implant placement, the characteristics of newly formed bone and dental implant stability were assessed. The methods used were radiography, scanning electron microscopy, light microscopy, micro-CT analysis, radio frequency analysis (RFA), and image analysis. There were no clinical adverse events in the post-operative period. New bone formation was similar for MBCP()/fibrin grafts and autografts at 21-20% and 20%, respectively, at 6 months, and at 34-35% and 35%, respectively, at 9 months. Implantability of dental implants was better at the time of placement with MBCP()/fibrin grafts than autografts at 81-88% and 69%, respectively. Three months after placement, RFA showed better implantability with MBCP()/fibrin grafts than with autografts at 75-82% and 71%, respectively. The bone contact measurements were around 50% for the three groups, without significant differences. This study shows that following sinus lift augmentation in sheep, MBCP()/fibrin grafts support new bone formation that is comparable to autografts, while providing better support for the dental implants.

    Full Text Available Introduction: The infraorbital nerve and foramen are bilateral structures, located below the lower edge of orbit (1,2,5,9,10,11,12, and are important surgical parameters for external access to the maxillary sinus (CaldwellLuc, representing its upper limit (4, 13. Objective: Establishing a safe average distance between the first premolar tooth alveolus top up to the foramen and infraorbital nerve, during the CaldwellLuc surgery. Method: We have analyzed 32 formolized heads of Brazilian adult corpses, without distinction of age, sex and race, within the period of February through July 2004. Surgical approach was made by CaldwellLuc passage, up to the complete exposure of infraorbital nerve and foramen where we delineated an imaginary line from the top of the first premolar tooth alveolus up to the foramen, and measured by using a pachymeter. Results: The general average distance between the structures mentioned was of 3.34cm with standard deviation of 0.52cm. The greater distance found was of 4,5 cm and the minor was of 2.5 cm bilaterally. Conclusion: When we know this region safe distance surgical access, we find less damage to the innervation that causes less intense subjective and less persistent symptoms in the post-operative period.

    Evidence is lacking to guide the postoperative management of Samter's triad patients with chronic rhinosinusitis with polyposis (CRSwP) undergoing endoscopic sinus surgery (ESS). The purpose of this study was to compare three different standardized medication regimens prescribed to these patients after ESS. Three-arm, randomized, double-blinded, controlled trial. Patients with Samter's triad undergoing ESS were postoperatively randomized into three medication regimens, those being saline irrigation alone (control group A), saline irrigation plus separate budesonide nasal spray (group B), and saline irrigation mixed with budesonide nasal spray (group C). Outcome measures were Sino-Nasal Outcome Test scores, Lund-Mackay computed tomography scores, and Lund-Kennedy endoscopic scores taken at preoperative baseline, and then at 6 months and 1 year postoperatively. Side effect profiles were also measured (adrenocorticotropic hormone blood level ranges and intraocular pressure at the same interval points). Analysis of variance and χ(2) analyses were conducted using a Bonferroni correction method and routine descriptive statistics. Inter- and intragroup comparisons were made. Sixty subjects were recruited. All groups were equivalent at baseline in all outcomes. All intragroup analyses showed statistically and clinically significant improvement in disease status as compared to baseline (P .05). There was no treatment effect noted. In this study, nasal steroids did not confer any additional benefit over saline alone as post-ESS care for the Samter's triad CRSwP patient population.

    Phlegmonous gastritis is a rare and often fatal condition that can affect healthy individuals in 50% of cases. The condition has been described in accounts dating back to the pre-antibiotic era, during which time mortality was nearly 100%. Over the past century, case reports average about one per year. The etiology remains unclear, although Streptococcus species is isolated frequently. The optimum treatment has not been delineated clearly but likely involves a combination of antibiotics with or without surgical resection. A case report was presented and the pertinent literature was reviewed. A 45-year-old man with a history of recent paranasal sinus surgery presented with acute abdominal pain and criteria consistent with toxic shock syndrome. Computed tomography scan showed diffuse thickening of the gastric wall and free intraperitoneal fluid. Exploratory laparotomy revealed a thickened stomach wall with outer fibrinous exudate and murky peritoneal fluid, which grew Streptococcus pyogenes. Intraoperative esophagogastroduodenoscopy revealed thickened gastric folds with a "cobblestone" appearance and no evidence of perforation. He was treated with antibiotics intravenously and sustained a difficult intensive care unit course complicated by ventilator-dependent respiratory failure, renal failure, and coagulopathy, but survived without major disability. This is an unusual case presentation of a rare but potentially lethal condition, whose optimal treatment is unclear. Phlegmonous gastritis should be considered when isolated gastric wall thickening is encountered in the clinical setting of toxic shock syndrome.

    An eyelid or orbital lipogranuloma can occur following nasal packing with liquid paraffin, petroleum jelly or an antibiotic-based cream. It usually presents a few weeks or months after the initial procedure. We present a report of three such cases of sclerosing lipogranuloma involving the eyelid, which occurred following a sinonasal surgery where nasal packing using petroleum jelly was performed. The typical clinical course and the classical histopathological features are highlighted. All cases were diagnosed by histopathological examination as sclerosing lipogranuloma. Complete surgical removal resulted in complete resolution on 1 month follow-up. The diagnosis is based on a high degree of suspicion following a detailed history of prior use of lipid-based products for nasal packing following endonasal surgery. Histopathology is diagnostic. Surgical excision is the treatment of choice, however, due to its infiltrative nature, it may be difficult to obtain a complete cure. 2015 BMJ Publishing Group Ltd.

    Full Text Available In power systems, the use of renewable energy, especially Wind power generation is steadily increasing around the world. However, this incorporation and the lack of controllability over the wind, and the type of generation used cause problems in the power quality and in the dynamics of the system. In this work, the use of a Distribution Static Synchronous Compensator (DSTATCOM coupled with a Flywheel Energy Storage System (FESS is proposed to mitigate problems introduced by the intermittency of wind power generation. A dynamic model of the DSTATCOM/FESS device is briefly presented and a multi-level control technique is proposed. The proposed control technique has one control mode for active power, and two control modes to choose between, for reactive power and voltage control. The above technique has been used here to enhance not only the steady state operation but also to mitigate sudden load changes. The control system under consideration, with the DSTATCOM/FESS, and its controls are analyzed also, under the conditions of different faults which may happen in the system.  Simulation tests of the device are analyzed when it is combined with wind generation in the electric system. The results demonstrate satisfactory performance of the proposed control techniques, as well as a high effectiveness of the control system to mitigate problems introduced by wind power generation.

    The aim of the study was to evaluate operative and long-term results of valve-sparing aortic root surgery in acute type A dissection. The repair consisted of selective replacement of all dissected and pathological sinuses. Forty-six patients (mean age 62 ± 14; range 29-88 years, 3 with Marfan syndrome), operated on between August 2001 and July 2011 due to acute type A aortic dissection, underwent valve-sparing root repair, resulting in a valve preservation rate of 56% in acute aortic dissection surgery involving the aortic root. Insufficiency grades of 0/1+, 2+, 3+ and 4+ were presented in 16, 17, 12 and 1 patients, respectively. Root repair with resection of the whole of the pathological aortic wall without the use of any glue was performed in all patients. Replacement of 1, 2 or 3 sinuses of Valsalva was performed in 29, 12 and 5 patients, respectively. Concomitant cusp repair was necessary in 7 patients. All perioperative data were collected prospectively and an intention-to-treat analysis was performed. A total of 6 patients (median age 76, range 63-81 years) died, on average 10 months (range 0.9-44) after surgery resulting in an overall survival of 87% at the mean follow-up of 54 ± 37, range 0.9-132 months. The linearized death rate was 2.9%/year, and the actuarial survival rate at 8 years was 85.5 ± 5.6%. No death was related to the aortic valve or aortic root. There were no valve-related events and no patient required reoperation on the proximal aorta/aortic valve during the follow-up. At the last echocardiography (47.8 ± 35.6 months after surgery), 33 patients showed no and 13 patients slight (1+) aortic insufficiency. Curative repair with replacement of all pathological sinuses of Valsalva leads to an excellent long-term outcome. Selected sinus repair is a simple and effective method of curative, valve-sparing root repair in acute aortic dissection because replacement of all sinuses is seldom necessary.

    To assess the efficacy of labetalol versus nitroglycerin for induction of controlled hypotension during sinus endoscopic surgery. A prospective, double-blind and randomized study. Carried out in operating room in university hospital. 60 patients of both sexes, American Society of Anesthesiologists (ASA) physical status I and II, age range from 20 to 60years; scheduled for elective sinus endoscopic surgery under general anesthesia (GA). Patients were divided into two groups (30 each). NTG group received nitroglycerin infusion at a dose of 2-5μg/kg/min, LAB group received labetalol infusion at a dose of 0.5-2mg/min. Surgical condition was assessed by surgeon using average category scale (ACS) of 0-5, a value of 2-3 being ideal. In both groups mean arterial blood pressure (MAP) was gradually reduced till the ideal ACS for assessment of surgical condition, the target of ACS was 2-3 or lower. Both studied drugs achieved desired hypotension and improved visualization of surgical field by decreasing bleeding in the surgical site, but ideal surgical conditions were created at mild hypotension (MAP 70-75) in LAB group while same conditions were created at MAP of 65-69mmHg in NTG group. Mean heart rate (HR) was significantly higher in NTG group as compared to LAB group. Blood loss decreased significantly in LAB group. Both labetalol and NTG are effective and safe drugs for induction of controlled hypotension during sinus endoscopic surgery. While, labetalol was better as it offered optimum operative condition with mild decrease in blood pressure, decreased surgical bleeding and less tachycardia during the surgery.

    We assessed the evidence for the use of α 2 -adrenergic agonists (A2AAs) in bleeding control and field quality in endoscopic sinus surgery. We systematically reviewed randomized clinical trials (RCTs) assessing A2AAs in endoscopic sinus surgery. Abstracts were reviewed by 2 investigators for eligibility, and selected articles were fully reviewed. Data on study design, population, A2AA drug and control groups, bleeding and surgical field quality outcomes, and adverse effects were extracted and synthesized. A total of 13 RCTs that included 896 individuals (7 double-blind trials, 5 single-blind trials, and 1 open-label trial) were selected that assessed the efficacy of clonidine (6 RCTs, 407 patients), dexmedetomidine (6 RCT, 423 patients), or both (1 RCT, 66 patients). Clonidine was compared with placebo (3 RCTs), midazolam (1 RCT), and remifentanil (2 RCTs). Dexmedetomidine was compared with esmolol (2 RCTs), remifentanil (2 RCTs), nitroglycerin and esmolol (1 RCT), and magnesium sulfate (1 RCT). Clonidine and dexmedetomidine were compared in 1 RCT. Clonidine reduced the proportion of individuals with an impaired surgical field by 23% vs placebo (number needed to treat = 4). Clonidine was better than midazolam and remifentanil in 2 trials, and dexmedetomidine was better than magnesium sulfate and esmolol in 2 trials but was not superior to esmolol, remifentanil, or nitroglycerin in 4 trials. Dexmedetomidine produced significantly better differences in bleeding outcomes versus clonidine. Adverse events were infrequent and mainly caused by hypotension or bradycardia. RCTs consistently report that A2AAs reduce bleeding and improve surgical field quality during endoscopic sinus surgery. Adverse event reporting was often omitted in RCTs. Well-designed RCTs with appropriate sample sizes are desirable to identify the best A2AAs and confirm their potential effects on clinical outcomes. Copyright © 2018 Elsevier HS Journals, Inc.

    Full Text Available Background and Aims: Endoscopic sinus surgery (ESS provides a challenge and an opportunity to the anesthesiologists to prove their mettle and give the surgeons a surgical field which can make their delicate surgery safer,more precise and faster. The aim of the study was to evaluate the surgical field and the rate of blood loss in patients premedicated with oral clonidine versus oral diazepam for endoscopic sinus surgery. Material and Methods: ASA I or II patients who were scheduled to undergo ESS were randomly allocated to group D (n = 30 or group C (n = 30. The patients′ vital parameters, propofol infusion rate, and rate of blood loss were observed and calculated. The surgeon, who was blinded, rated the visibility of the surgical field from grade 0-5. Results: In the clonidine group, the rate of blood loss, the surgical time, propofol infusion rate was found to be statistically lower as compared to the diazepam group. Also a higher number of patients in the clonidine group had a better surgical score (better surgical field than the diazepam group and vice versa. Conclusions: Premedication with clonidine as compared to diazepam, provides a better surgical field with less blood loss in patients undergoing ESS.

    We have developed a regenerative medicine therapy for the alveolar bone and endoscopic surgery for maxillary sinus lift without bone grafts, in patients experiencing severe periodontal disease with significant absorption of the maxillary alveolar bone, in which more than 10 mm of bone thickness in the maxillary bone was attained, with satisfactory results. The objective of this study was to examine the treatment outcomes of implants that were performed after these therapies. The participants were 36 patients with severe periodontal disease, who cannot be cured with any other treatments except the extirpation of all teeth. The 36 patients are all patients who underwent regenerative treatment of the alveolar bone through tooth replantation and transplantation of the iliac cancellous bone (the bone marrow) as well as endoscopic surgery for maxillary sinus lift from May 2003 to July 2007 in our clinic. A total of 120 implants were placed in these patients when the replanted teeth fell out because of root resorption, and the success rate was examined. The success rates of the implants were 16 of 33 (48%) in the group when surveyed less than 2 years after the surgery and 84 of 87 (96.5%) in the group when surveyed more than 2 years after the surgery. A statistically significant difference was found between the 2 groups (Chi-squared test, P implant placement. Therefore, although the implant treatment should be performed later than 2 years after surgery, chewing is possible during this period, with the replanted teeth that were used for regenerative treatment of the alveolar bone. It is believed that this is an extremely effective treatment method to improve the patients' quality of life.

    No studies are available that provide predictive parameters regarding the expected amount of resorption after maxillary sinus augmentation surgery using autologous bone grafts. Therefore, the aim of this study was to determine parameters influencing the outcome of the bone graft resorption process. In 20 patients, three-dimensional analysis of alveolar ridge dimensions and bone graft volume change in the atrophic posterior maxilla was performed by Cone-Beam Computerized Tomography imaging. Ridge dimensions were assessed before maxillary sinus augmentation surgery. Bone graft volumes were compared after maxillary sinus floor augmentation surgery and a graft healing interval of several months. To analyze the relation between bone volume changes with the independent variables, patients' gender, age, alveolar crest height and width, and graft healing time interval, a multi-level extension of linear regression was applied. A residual bone height of 6.0 mm (SD = 3.6 mm) and 6.2 mm (SD = 3.6 mm) was found at the left and right sides, respectively. Moreover, alveolar bone widths of 6.5 mm (SD = 2.2 mm) and 7.0 mm (SD = 2.3 mm) at the premolars, and 8.8 mm (SD = 2.2 mm) and 8.9 mm (SD = 2.5 mm) at the molars regions were found at the left and right site, respectively. Bone graft volume decreased by 25.0% (SD = 21.0%) after 4.7 months (SD = 2.7, median = 4.0 months) of healing time. The variables "age" (P = 0.009) and mean alveolar crest "bone height" (P = 0.043), showed a significant influence on bone graft resorption. A decrease of 1.0% (SE = 0.3%) of bone graft resorption was found for each year the patient grew older, and an increase in bone graft resorption of 1.8% (SE = 0.8%) was found for each mm of original bone height before sinus floor augmentation. Graft resorption occurs when using autologous bone grafts for maxillary sinus augmentation. Alveolar crest bone height and patient age have a significant effect on graft

    The questionnaire for the assessment of the voice selfconcept (FESS) contains three sub-scales indicating the personal relation with the own voice. The scales address the relationship with one's own voice, the awareness of the use of one's own voice, and the perception of the connection between voice and emotional changes. A comprehensive approach across the three scales supporting a simplified interpretation of the results was still missing. The FESS questionnaire was used in a sample of 536 German teachers. With a discrimination analysis, commonalities in the scale characteristics were investigated. For a comparative validation with voice health and psychological and physiological wellbeing, the Voice Handicap Index (VHI), the questionnaire for Work-related Behavior and Experience Patterns (AVEM), and the questionnaire for Health-related Quality of Life (SF-12) were additionally collected. The analysis provided four different groups of voice self-concept: group 1 with healthy values in the voice self-concept and wellbeing scales, group 2 with a low voice self-concept and mean wellbeing values, group 3 with a high awareness of the voice use and mean wellbeing values and group 4 with low values in all scales. The results show that a combined approach across all scales of the questionnaire for the assessment of the voice self-concept enables a more detailed interpretation of the characteristics in the voice self-concept. The presented groups provide an applicable use supporting medical diagnoses. © Georg Thieme Verlag KG Stuttgart · New York.

    With pilonidal sinus disease (PSD) incidence increasing and patients freely choosing their surgeon, patients' interest issues have been brought forward estimating patient satisfaction following pilonidal sinus surgery. The influence of wound healing time and long-term recurrence rate on patient satisfaction in primary PSD surgery has not been investigated yet. Five hundred eighty-three patients (German military cohort) were interviewed, compiling wound healing time, aesthetic satisfaction, long-term recurrence-free survival and patient satisfaction having undergone primary open (PO) treatment, marsupialization (MARS) or primary midline closure (PMC) treatment. Recurrence rate was determined by Kaplan-Meier calculation following up to 20 years after primary PSD surgery. Patient satisfaction ranking from 1 to 10 (10 = max. satisfied) showed an average satisfaction of 8.2 (range 0-10; 95% confidence interval (CI) 7891-8250). In-hospital stay time was significantly longer in primary open (PO) and marsupialization (MARS) group as compared to primary midline closure (PMC; p < 0.0001, Kruskal-Wallis test). Satisfaction was comparable between treatment groups, and was neither linked to in-hospital stay time nor to longer outpatient wound care period or total treatment time. Recurrence-free survival, as seen in the PO and PMC treatment group, revealed a highly significant difference for all patients. Improvement in MARS patients with versus without recurrence was low, as satisfaction with primary treatment was lower as the other groups. Neither choice of surgical treatment nor treatment duration within hospital or after hospital influences patient satisfaction, as long as recurrence-free survival can be provided. Marsupialization was ranked lower in both groups (with or without recurrence), and should be abandoned, as patients are significantly less satisfied with either results, independent of recurrence.

    The concept of "prosthetic-driven implantology" may be considered a turning point in the history of modern dental implantology. On the basis of this sophisticated approach, the available bone and the optimal prosthetic position of the future restoration are checked before surgical intervention. However, the major drawback of today's prosthodontic discipline is that it is inherently 2-dimensional in nature, which may prevent the appropriate treatment; this problem can be overcome by the 3-dimensional capability of a computer-assisted approach when performed judiciously. It was proposed that this technique has the potential to provide a high level of safety and accuracy in comparison to traditional surgical procedures. Using a novel approach, we performed modified flapless implant surgery accompanied by a simultaneous sinus-lifting procedure. The technique used a 3-dimensional life-sized computer-aided design/computer-aided manufacturing (CAD/CAM) model prepared from the computed tomography images for prosthetic/surgical diagnosis and treatment planning. The procedure of implant planning, model surgery, and sinus floor augmentation in this sophisticated flapless surgical approach has the potential to provide substantial benefits for both patients and practitioners. The versatility of the described technique not only allows more accurate implementation of the treatment plan to the patient's mouth but also may offer many additional significant benefits, including the use of custom surgical guides, life-sized bone model manipulation, and surgical rehearsal, all of which are very difficult to achieve with current traditional procedures.

    Alveolar ridge reduction caused after tooth extraction can be minimized through ridge preservation and application of graft materials. The aim of this study was to compare the histologic and histomorphometric aspects of bone particulated allografts, Cenobone and ITB-MBA, in the reconstruction of vertical alveolar ridge after maxillary sinus augmentation. This clinical trial was performed among 20 patients. The participants were randomly divided into two groups of 10 participants. The first group received Cenobone and the second group received ITB-MBA. Tissue samples were prepared 6 months later at the time of implant installation and after successful maxillary sinus floor augmentation. Tissue sections were examined under a light microscope. The data were analyzed by Chi-square and t -test. The mean trabecular thickness of the samples in the Cenobone group was 13.61 ± 7.47 μm compared to 13.73 ± 7.37 μm in the ITB-MBA group ( P = 0.93). A mild inflammation process (Grade 1) was detected in both the groups. The amount of remaining biomaterial in the Cenobone group was estimated to be 8 ± 19% vs. 7 ± 12% in the ITB-MBA group ( P = 0.30). Bone formation was reported 49.71% in the Cenobone group vs. 40.76% in the ITB-MBA group ( P = 0.68). The mean newly formed vessel in the Cenobone group was 0.64 ± 0.7 vs. 1.5 ± 2.3 in the ITB-MBA group ( P = 0.14). There was no significant difference between the two groups of patients regarding trabecular thickness, remaining biomaterial allograft, and the density of blood vessels after sinus floor elevation; hence, there was no difference between the two groups regarding implant outcome. More designed studies as randomized controlled trials and controlled clinical trials, which evaluate the long-term implant outcome; comparing the different bone graft materials is also required to improve evidence on survival and success rate.

    We report herein on 5 patients with odontogenic maxillary sinusitis caused by a dental restoration (caries cutting, cavity preparation, inlay restoration). Odontogenic maxillary sinusitis was noted following dental restoration. Even though the pulp cavity and dental pulp were intact, the odontogenic maxillary sinusitis occurred caused by an apical lesion. Infection by way of the dentinal tubules was suggested to be a cause of the pathophysiology. Endoscopic sinus surgery was indicated in patients with intractable odontogenic maxillary sinusitis caused by the dental restoration. Cone-beam x-ray CT was useful for the accurate diagnosis of odontogenic maxillary sinusitis caused by a dental restoration. Physicians should thus be aware of the possibility that a tooth, which has undergone dental restoration, may cause odontogenic maxillary sinusitis.

    Dorsal sagittal venous sinus (DSVS) is an encephalic structure located in the midline of brain dorsal surface, starting behind the frontal venous sinus and following the brain falx in its extension. Knowing DSVS morphology and cranial-cerebral relationships it is very important for surgeon when he is planning the placement of craniotomies, in order to prevent the damage of this structure. The main purpose of this study were to establish craniometric points that can be used as key points of neurosurgical importance providing an anatomic framework to brain access regarding the localization of DSVS, and to characterize the morphology of DSVS in the three groups considered in study according their type of skull (brachycephalic-B, dolychocephalic-D and mesocephalic-M). The study was performed on 138 formalin-fixed cerebral hemispheres of 69 adult dog cadavers (23 of each group) which had been removed from the skulls after the introduction of plastic catheters through properly positioned burr holes placed on the five craniometric points considered: asterion(ast), bregma(br), glabella(g), stephanion(st) and pterion(pt). From the three groups, DSVS length and width were different, his geometry in B assumed a triangular appearance and in D, M a "butterfly" shape. From all craniometric points considered, only bregma (br) can be useful as a landmark to delimitate DSVS morphology in all three groups. Asterion in M, stephanion in B, glabella and pterion in all three groups, can not be used to compose a framework that help to understand skull surface projection of DSVS morphology, since their measurements were not uniform.

    Patel, Nimish A; Ferguson, Berrylin J

    2012-02-01

    For well over 100 years, it has been appreciated that maxillary dental infections can cause sinusitis. This insight has been largely overlooked with the advent of functional endoscopic sinus surgery (ESS) and its emphasis on the osteomeatal complex. We review several recent case series and reviews of odontogenic sinusitis that characterize and discuss emerging diagnostic modalities in odontogenic sinusitis. In recent publications on odontogenic sinusitis, up to 40% of chronic bacterial maxillary sinus infections are attributed to a dental source, which is far higher than the previously reported incidence of 10%. Plain dental films and dental evaluations frequently fail to detect maxillary dental infection that can be causing odontogenic sinusitis. However, sinus computed tomography (CT) or Cone Beam Volumetric CT (CBVCT) are far more successful in identifying dental disease causing sinusitis. The microbial pathogens of odontogenic sinusitis remain unchanged from earlier reviews; however, the clinical findings in odontogenic sinusitis are better described in recent reviews. Successful treatment of odontogenic sinusitis requires management of the odontogenic source and may require concomitant or subsequent sinus surgery. Odontogenic sinusitis is frequently recalcitrant to medical therapy and usually requires treatment of the dental disease. Sometimes dental treatment alone is adequate to resolve the odontogenic sinusitis and sometimes concomitant or subsequent ESS is required. Evaluation of all patients with persistent chronic rhinosinusitis (CRS) should include inspection of the maxillary teeth on CT scan for evidence of periapical lucencies. Unilateral recalcitrant disease associated with foul smelling drainage is especially characteristic of odontogenic sinusitis. High-resolution CT scans and CBVCT can assist in identifying dental disease.

    A group of 86 patients with osteomas on the bones of the skull and face, 21 suffered from osteomas of the paranasal sinuses. The mean age of the patients was 50 years, with a predominance of male subjects (2/1). The frontal sinus was the frequently involved (57%), followed by the maxillary, ethmoid and the sphenoid sinuses. Diagnosis was made accidentally in 45% of the cases. The most frequent presenting symptom was headache (57%). Simple excision of the osteoma paranasal sinus was possible in 18 cases. We realize a study of the facts, as well as a review of the literature to know the incidence, diagnosis, indications and surgery technics used in these type of osteomas.

    Maxillary sinus lift surgery (MSLS) is considered to be a useful treatment method for patients with atrophic alveolar bone. Choosing a suitable surgical procedure to simultaneously decrease graft absorption and obtain long-term survival of dental implants is still a challenge. In this study, 20 patients received MSLS with graft of bone morphogenetic protein 2 (BMP2)-loaded calcium phosphate. Dental implants were placed simultaneously in 10 patients receiving MSLS (1-stage group), and in 10 patients receiving dental implants with a 3 to 6 months delay (2-stage group). The effects were evaluated based on clinical and radiographic examination during a 4 to 5 years follow-up. The results showed that only 1 perforation of the maxillary sinus mucosa was observed in 1-stage group, and was patched with a collagen membrane. An average bone gain of 6.8 mm was observed, and all implants exhibited no looseness, peri-implantitis, or fracture, all of which were stable during the follow-up and exhibited nice dental function during a 4 to 5 years follow-up. The loss of peri-implant bone height was 1.12 ± 0.47 and 1.10 ± 0.39 mm, the probing depth of periodontal pocket was 1.79 ± 0.62 and 1.81 ± 0.71 mm, the sulcular bleeding index was 1.63 ± 0.47 and 1.72 ± 0.54 in 1-stage group and 2-stage group, respectively, and no significant differences existed between these 2 groups. These findings implied that BMP2-loaded calcium phosphate may be a suitable material for MSLS, especially for patients with minimal bone height. Clinicians can use the 1- or 2-stage technique based on clinical condition, patients' choice and clinicians' experience. In patients where implants cannot be stabilized for patients with minimal bone height, 2-stage surgery may be more suitable.

    Clinical parameters of 72 patients who were operated upon for nasal polyps were evaluated as well as biopsy specimens of the mucosa of the middle and inferior turbinates of 41 of these patients. Biopsies were taken at the time of endoscopic sinus surgery (ESS), after 6 months and after 1 year in 23 patients. During the follow-up period the patients were treated with topical corticosteroids (budesonide). At the time of ESS significantly more CD8+ (suppressor/cytotoxic) cells than CD4+ (helper/inducer) cells were found in the middle and inferior turbinates. At 6 months significantly more CD4+ cells were found than at the time of ESS, whereas at 1 year the number of CD4+ cells had decreased and was lower than at 6 months. These data support the theory that the occurrence of nasal polyps is associated with T-cell-dependent disturbances. Clinical evaluation revealed that most of the patients with chronic airway obstruction had better pulmonary functions postoperatively or required less medication for lung disease. These findings show that ESS combined with topical corticosteroids has a positive effect on upper and lower respiratory tract pathology.

    The time-driven activity-based costing (TD-ABC) method is a novel approach to quantify the costs of a complex system. The aim of this study was to apply the TD-ABC technique to define the overall cost of a routine outpatient endoscopic sinus surgery (ESS) from the perspective of the Canadian government payer. Costing perspective was the Canadian government payer. All monetary values are in Canadian dollars as of December 2012. Costs were obtained by contacting staff unions, reviewing purchasing databases and provincial physician fee schedules. Practical capacity time values were collected from the College and Association of Registered Nurses of Alberta. Capacity cost rates ($/min) were calculated for all staff, capital equipment, and hospital space. The overall cost for routine outpatient ESS was $3510.31. The cost per ESS case for each clinical pathway encounter was as follows: preoperative holding ($49.19); intraoperative ($3296.60); sterilization ($90.20); postanesthesia care unit ($28.64); and postoperative day ward ($45.68). The 3 major cost drivers were physician fees, disposable equipment, and nursing costs. The intraoperative phase contributed to 94.5% of the overall cost. This study applied the TD-ABC method to evaluate the cost of outpatient ESS from the perspective of the Canadian government payer and defined the overall cost to be $3510.31 per case. © 2013 ARS-AAOA, LLC.

    The volume of the maxillary sinus was estimated by coronal CT scan. The purpose of this study was to compare the estimated volume of the normal maxillary sinus with that of the inflamed maxillary sinus. Patients were classified following evaluation by CT scan of the paranasal sinuses into 3 categories. Group A (n=12): Patients suffered from headache, facial pain and epistaxis, but CT scans of their nasal cavity and paranasal sinus were within normal limits without inflammatory change. Group B (n=69): Patients with bilateral chronic maxillary sinusitis, CT scans of whom showed inflammatory changes in both maxillary sinuses. All of the patients in this group underwent sinus surgery after coronal CT scans. Group C (n=14): Patients with unilateral chronic maxillary sinusitis, CT scans of whom showed inflammatory change in unilateral maxillary sinuses. CT scans of these patients were measured by Plannimeter to take the area of each image of the maxillary sinus. Consecutively imaged areas were summated by integral calculus to obtain an estimate of the sinus volume. The mean maxillary sinus volume in the affected sinuses was significantly smaller than those in the contralateral normal sinuses (p<0.05, Wilcoxon-test). The various volumes of the maxillary sinuses and the developmental cause were discussed. Comparison of groups A with B suggested three distinct patterns; the maxillary sinus volume has decreased due to inflammatory changes in the bone. The small sinuses have a tendency to develop chronic inflammatory change. The aeration in the maxillary sinus may be decreased when anatomic variations that may obstruct the ethmoid infundibulum exist. (K.H.)

    Persistent mucosal inflammation in patients with chronic rhinosinusitis (CRS) often results in ongoing symptoms, recurrence of polypoid mucosa, infective exacerbations, and further systemic medication despite surgical intervention. Debate exists as to the most effective topical therapy in CRS. The objective was to determine if corticosteroid delivered via a nasal irrigation or via a simple nasal spray would be more effective in controlling the symptoms and signs of CRS. A double-blind placebo-controlled randomized trial over 12 months was performed between 3 tertiary rhinologic clinics. After sinus surgery, all patients performed a nasal irrigation followed by a nasal spray once a day for 12 months. Groups were defined by corticosteroid (2 mg mometasone) delivered by either spray or irrigation. The primary outcomes were patient-reported symptoms: visual analogue score (VAS) and 22-item Sino-Nasal Outcome Test (SNOT-22), a global rating of sinonasal function. Secondary outcomes were also recorded from radiology (Lund-Mackay score [LMS]) and endoscopic (Modified Lund-Kennedy score [mLKS]) assessments. A total of 44 patients were randomized (age 50.3 ± 13.0 years; 40.9% female). Overall, patients improved significantly from either intervention. However, the corticosteroid nasal irrigation group had greater improvement in nasal blockage (-69.91 ± 29.37 vs -36.12 ± 42.94; p = 0.029), a greater improvement on LMS (-12.07 ± 4.43 vs -7.39 ± 6.94; p = 0.031) and less inflammation on mLKS at 12 months (7.33 ± 11.55 vs 21.78 ± 23.37; p = 0.018). One-year posttreatment blockage, drainage, fever, and total VAS scores were all lower in the corticosteroid irrigation group. In the setting of diffuse or patchy CRS disease, the use of corticosteroid delivered by nasal irrigation is superior to simple nasal spray in postsurgical patients. © 2018 ARS-AAOA, LLC.

    The catalytic hydroliquefaction of Xiaolongtan lignite (XL, a Chinese lignite) was investigated in a batch autoclave. The effects of reaction temperature, time and initial H{sub 2} pressure on the yields of gaseous and extractable portions (GEPs) were discussed. The catalytic activity of FeS+S was compared with that of FeS and SO{sub 4}{sup 2-}/ZrO{sub 2}, respectively. The results show that FeS+S is more active for XL hydroliquefaction than the other two catalysts and affords the highest gas and oil (G & O) yields in the three catalysts. The highest total yield of GEPs from XL hydroliquefaction gets to 90.0%, while total yield of G & O is 61.1% at 420 {sup o}C for 30 min over FeS+S. The assistant catalysis of the added sulfur was discussed. The structural features of asphaltenes and preasphaltenes were examined by elemental and FTIR analyses.

    To describe the diagnosis and treatment of ectopic pyriform sinus parathyroid adenoma. A 44-year-old woman presented with persistent primary hyperparathyroidism after previous failed cervical exploratory surgery. Diagnosis of ectopic pyriform sinus parathyroid adenoma was suggested by computed tomography and technetium-99m sestamibi scintigraphy (99mTc-MIBI SPECT/CT). A submucosal tumor was identified under laryngoscopy and resected by endoscopic CO2 laser. Histopathology confirmed the diagnosis of parathyroid adenoma. Ectopic pyriform sinus locations are rare in parathyroid adenoma. 99mTc-MIBI SPECT/CT facilitates diagnosis, especially in case of previous failed neck exploration. Endoscopic CO2 laser resection is the treatment of choice. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

  11. A Rational Approach to Sinus Augmentation: The Low Window Sinus Lift

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Sinus augmentation is a well-known approach to treating alveolar bone ridge atrophy in the posterior maxilla. The preparation of the lateral window is crucial. Its size, design, and position in the vestibular sinus wall may affect the intra- and postsurgical complication rates and affect the intrasurgical activity of both surgeons and assistants. The present paper describes a rational technique that also exploits the guided surgery approach for design and preparation of a lateral window for sinus augmentation, the Low Window Sinus Lift. To illustrate the use of this approach, a case is presented in which the 50-year-old patient had the left maxillary first molar extracted, followed two months later by sinus augmentation and placement of three implants. One year after delivery of the definitive prosthesis, all three implants were successful, and the prosthesis was fully functional. Controlled studies should be undertaken to assess whether this technique provides significant advantages compared to other sinus augmentation approaches.

    To assess the presentation of allergic fungal sinusitis and describe the line of management in our setup. Culture and sensitivity / fungal stain proven 20 cases of allergic fungal sinusitis were selected for the study, irrespective of age and gender. Data including age, gender, socioeconomic status, signs, symptoms, laboratory findings (especially Immunoglobulin E and eosinophil count) and imaging studies (Computed Tomography and /or Magnetic Resonance Imaging) were noted for the study. Pre and postoperative medical treatment, surgery performed, follow-up; residual/recurrence disease and revised surgery performed were also recorded. In this series, allergic fungal sinusitis was a disease of younger age group with an average age of 20.75 years with male dominance (70%). Poor socioeconomic status (80%), allergic rhinitis (100%) and nasal polyposis (100%) were important associated factors. Nasal obstruction (100%), nasal discharge (90%), postnasal drip (90%) and unilateral nasal and paranasal sinuses involvement (60%) were the commonest presenting features. Aspergillus (60%) was the most common etiological agent. In all cases (100%), increased eosinophil count and IgE levels were present. Orbital (20%) and intracranial (10%) involvement were also seen. Surgical management was preferred in all cases. Functional endoscopic sinus surgery in 90% cases and lateral rhinotomy in 10% cases were performed. Recurrence / residual disease was seen in 20% cases. In this series, allergic fungal sinusitis was seen in immunocompetent, young males, belonging to poor socioeconomic status, suffering from allergic rhinitis and nasal polyposis, presenting with nasal obstruction, nasal discharge and postnasal drip. Functional endoscopic sinus surgery was the most important problem solving procedure while lateral rhinotomy was reserved for extensive disease. (author)

    Surgery for chronic rhinosinusitis is an effective complement to a well-designed medical regimen. Functional endoscopic sinus surgery is among the most common surgeries performed for sinonasal disease refractory to maximal medical therapy. Nasal surgery techniques, such as septoplasty and inferior turbinate surgery, may assist in both relieving the symptom of nasal obstruction and providing access for sinus surgery. Although rare, open sinus techniques are occasionally required.

    Cemento-ossifying fibromas are a group of rarely occurring benign tumours, developing from the periodontal membrane and varying considerably in appearance and in the progress of the disease. Their common feature is higher or lower production of cemental tissue. In most cases the tumours are small because their cementoma mature quickly and become inactive, which causes the tumour to stop growing. They develop most frequently in the mandible and also in the maxilla. Other sites, such as paranasal cavities, soft tissues and bones of the head, are extremely rare. The case of a cemento-fibrosing tumour with psammoma infiltrations, developing from the ethmoid sinus in a nine-year-old girl is reported. Due to frontal headaches and sight defects as well as impaired vision on the right side, NMR was done, which showed a mucocele of the front and rear ethmoid with destruction of the orbital wall and a breakthrough into the orbit. The right maxillary sinus showed a visible retention and a thickened mucous membrane. A rhinoscopy revealed a ball-shaped spherical mass in the medial nasal meatus, which was defined as concha bullosa. An endoscopic examination showed that the tumour protruded in front of the medium nasal concha into the right nasal cavity, softened the ethmoid roof, penetrated toward the base of the skull, adhered and pushed the orbit. It was removed by FESS technique, and PHD revealed subsequently that it was not a mucocele but a cemento-ossifying fibroma. PMID:27688399

    Maxillary sinus hypoplasia (MSH) is an uncommon abnormality of paranasal sinuses noted in clinical practice. Computed tomography (CT) scan helps in diagnosing the anomaly along with any anatomical variation that may be associated with it. MSH is usually associated with other anomalies like uncinate process hypoplasia. Three types of MSH have been described. Type 1 MSH shows mild maxillary sinus hypoplasia, type 2 shows significant sinus hypoplasia with narrowed infundibular passage and hypoplastic or absent uncinate process, and type 3 is cleft like maxillary sinus hypoplasia with absent uncinate process. CT and endoscopic examination usually complement each other in diagnosing MSH. PMID:25548709

    2011-10-01

    Full Text Available Mucoceles of the paranasal sinuses are slowly growing, epithelium-lined cystic lesions with sterile content. When the mucocele content becomes infected with a bacterial super-infection, the lesion is defined as mucopyocele. Mucoceles or mucopyoceles are commonly located in the frontal and anterior ethmoidal sinuses and can manifest with ocular signs and symptoms, mostly proptosis. In this report, we demonstrate a case of bilateral ethmoidal mucopyocele in a 53-year-old female who presented with reduced vision, diplopia, and proptosis. Computed tomography (CT scanning of the paranasal sinuses revealed cystic lesions filling the maxillary sinuses and anterior ethmoidal cells bilaterally and causing erosion in the walls of the sinuses. After marsupialization of the mucopyoceles was performed by endoscopic sinus surgery, the symptoms of the patient recovered rapidly. (Turk J Ophthalmol 2011; 41: 354-6

    Full Text Available Introduction: Fungal sinusitis is a well known disease in immunocompromised patients, but recently many reports have indicated an increased prevalence of fungal sinusitis in otherwise healthy individuals. The aim of this study was to assess the frequency of invasive fungal sinusitis (IFS in neutropenic patients and to determine outcome factors that may affect their survival. Methods: A total of 142 patients who were undergoing chemotherapy were followed by clinical and radiological features suggestive of fungal sinusitis. Patients with fever, headache, facial swelling and radiological finding underwent endoscopic sinus surgery. The biopsy materials were studied by mycological and histopathological methods. Results: Eleven from 142 patients were identified to have IFS. The ethiologic agents were Aspergillus flavus (5 cases, Alternaria sp. (3 cases, Aspergillus fumigatus (2 cases and mucor (1 case. Eight of 11 cases died. Conclusions: Invasive fungal sinusitis causes a high rate of mortality among immunocompromised patients. Therefore, early diagnosis with aggressive medical and surgical intervention is critical for survival.

  14. CT characterization of inflammatory paranasal sinus disease in cystic fibrosis

    2002-01-01

    Purpose: In patients with cystic fibrosis (CF) the prevalence of paranasal sinus affection approaches 100%. We hypothesized that the hyper viscous mucus reducing mucociliary clearance in CF patients could give sinonasal inflammatory patterns different from those in non-CF patients. We wanted to compare the extent and distribution of paranasal sinus disease and the inflammatory patterns in these two groups of patients. Material and Methods: One-hundred-and-eight CF patients (3-54 years old) and 79 controls (7-51 years old) with paranasal sinus disease confirmed at coronal CT were compared. The extent of disease was noted for each sinus and summed for all sinuses. Inflammatory patterns were identified and classified into: 1) routine surgery group (sporadic, infundibular and ostiomeatal complex (OMC) patterns) and 2) complex surgery group (sinonasal polyposis and sphenoethmoid recess (SER) patterns). Results: CF patients had more widespread sinonasal inflammatory changes and more advanced disease for each sinus. Most CF patients displayed sinonasal polyposis and SER patterns while most controls displayed sporadic, infundibular or OMC patterns. As a result, 67% of CF patients were classified to the complex surgery group, compared to only 19% of controls. Conclusion: The impaired mucociliary clearance in CF causes widespread inflammatory paranasal sinus disease, with inflammatory patterns more often requiring extensive surgery, with a higher risk of cerebrospinal fluid leak or bleeding, or involving areas that are more difficult to reach with the endoscope

    To propose a standard value for the maxillary sinus volume of a normal Korean adult by measuring the width and height of the sinus and analyzing their correlation and the difference of the sinus size respectively between sexes, and on the right and left sides. Fifty-two (95 maxillary sinuses) out of 20 years or over aged patients who had taken CT in the Department of Dental Radiology, Yonsei University, Dental Hospital, between February 1997 and July 1999 who were no specific symptom, prominent bony septa, pathosis, clinical asymmetry and history of surgery in the maxillary sinus were retrospectively analyzed. The mean transverse width, antero-posterior width, height and volume of the normal Korean adult's maxillary sinuses were 28.33 mm, 39.69 mm, 46.60 mm and 21.90 cm 3 , respectively. There was a significant sex difference in the sinus volume (p<0.05). In the mean antero-posterior width, height and volume of the sinus, no significant difference was observed between both sides. All four measurements showed a significant correlation between both sides (p<0.0001). The widths and height of the sinus all showed a significant correlation with the sinus volume (p<0.0001). In the Korean normal adult's maxillary sinus, males tended to be larger than females. Except for the transverse width, all of the measurements showed no significant difference between the right and left side, but significant correlations in the four measurements between both sides were observed. Thus, the overgrowth or undergrowth in the unilateral maxillary sinus may suggest a certain pathosis or developmental abnormalities in the maxillary sinus.

    2013-01-01

    Full Text Available Introduction. An antrolith is a calcified mass within the maxillary sinus. The origin of the nidus of calcification may be extrinsic (foreign body in sinus or intrinsic (stagnant mucus and fungal ball. Most antroliths are small and asymptomatic. Larger ones may present as sinusitis with symptoms like pain and discharge. Case Report. We report a case of a 47-year-old lady who presented with heaviness on the left side of the face and loosening of the left 2nd molar tooth since two months. CT scan of the osteomeatal complex and paranasal sinuses showed an opacification of bilateral maxillary sinus and an amorphous area of bone density in the left maxillary sinus. Because of the size of the mass, benign neoplasms were considered in the differential diagnosis. During an endoscopic sinus surgery, it was found to be an antrolith, which was successfully managed by antrostomy and Caldwell-Luc Surgery. Discussion. Antrolith is a rare condition. Rhinoliths are known to invade into the maxillary antrum, but a localised lesion in the antrum is very unusual. A case of an isolated antrolith is presented for its rarity and for differential diagnosis of localised antral disease. Conclusion. Antrolith should be considered as differential diagnosis of unilateral radio-opaque paranasal sinus lesions.

    Allergic fungal sinusitis is a recently described clinical entity that has gained increased attention as a cause of chronic sinusitis. Consist in a benign noninvasive sinus disease related to a hypersensitivity reaction to fungal antigens. It should be suspected in any atopic patient with refractory nasal polyps. Computed tomography (CT) findings are characteristics, but not diagnostic. Diagnosis requires show allergic mucin in the histopathologic examination and hiphae in special fungal stains. The suitable treatment includes the allergic mucin removal and sinus aeration accomplished endoscopically, perioperative systemic steroids and immunotherapy with fungal antigens. We present a case of this kind of chronic sinusitis describing the characteristic histopathologic and radiologic findings, the pathogenic theories and recent advances in immunotherapy.

    Genital ambiguity is a very common phenomenon in disorders of sex development (DSD). According to the Chicago Consensus 2006, feminizing genitoplasty, when indicated, should be performed in the most virilized cases (Prader III to V). Advances in the knowledge of genital anatomy in DSD have enabled the development and improvement of various surgical techniques. Mobilization of the urogenital sinus (MUS), first described by Peña, has become incorporated by most surgeons. However, the proximity of the urethral sphincter prompts concern over urinary incontinence, especially for full mobilization of the urogenital sinus. To retrospectively evaluate the short-term surgical results of feminizing genitoplasty with total mobilization of the urogenital sinus in patients with DSD. Review of medical records of all patients undergoing feminizing genitoplasty with mobilization of the urogenital sinus. We evaluated the rates of complications from surgery and of urinary incontinence, as well as cosmetic results, according to the opinion of the surgeon and the family. A total of 8 patients were included in the study. The mean age at surgery was 51months. Congenital adrenal hyperplasia (CAH) was diagnosed in six patients, and gonadal dysgenesis in the other two. The vagina was separated from the urethra, with suitable distance in all cases. No patient had urinary incontinence after surgery. The mean follow-up of patients was. 20months (3-56months). In all cases, surgeons recorded being satisfied with the aesthetic result of post-surgical genitalia. The family was recorded as satisfied with the aesthetic result of the genitalia after surgery. In every case, there was no need for a second surgical procedure. The total mobilization of the urogenital sinus is a feasible and safe technique. The technique permits good cosmetic results, and urinary incontinence is absent. Therapeutic study. Level III. Copyright © 2017 Elsevier Inc. All rights reserved.

    To date, no studies have been published that evaluated histomorphometric data from a large number of patients while comparing different sites and methods of autologous bone grafting in sinus floor augmentation procedures. A meta-analysis of the English literature from January 1995 till April 2009 was carried out. PubMed search engine and the following journals were explored: Clinical Oral Implant Research, International Journal of Oral and Maxillofacial Implants, International Journal of Periodontics and Restorative Dentistry, and the Journal of Periodontology. Out of 147 titles, according to our criteria, 25 articles were left for analysis. The majority were prospective controlled studies (21) and 2 randomized clinical trials, 1 pilot study and 1 case series. A reference value of 47% for total bone volume (TBV) was found while using iliac bone grafting as a standard. Use of intraoral bone grafts increases the TBV, with 11% for chin bone and 14% for bone grafted from other intraoral sites. Particulation of the bone graft has a negative effect on the TBV of 18%. Surprisingly, no correlation between TBV and the time of graft healing was found. Histological section thickness seemed to be a significant variable, as every micron increase of section thickness leads to an increase of 0.4% of TBV. Bone grafting from the iliac crest resulted in a significantly lower TBV compared with intraoral bone grafting. However, due to the limited availability of intraoral bone to be harvested, iliac grafts still have to be considered the gold standard in augmenting the severely atrophic maxilla.

    Although craniofacial bone is the second common site of fibrous dysplasia involvement, it is rarely found in the paranasal sinus. Among fibrous dysplasia of the head and neck, the maxilla and mandible are the most frequent sites to be involved. Fibrous dysplasia becomes dormant in adolescence and early adult life and is more common in female. It is one of the fibrous osseous lesions and should be differentiated from osteoma and ossifying fibroma. Radiographically, fibrous dysplasia showed "groundglass" bone appearance on CT scans with bone window. Histopathologically, it presents woven-type bone embedded in a cellular fibrous stroma without osteoblastic rimming. We presented a case of 25-year-old female with fibrous dysplasia in her right side ethmoid sinus. She visited to us with the chief complaint of right side headache since adolescence. The lesion was removed by endoscopic sinus surgery and pathology proved fibrous dysplasia. The patient was free of headache after operation. The advance of endoscopic sinus surgical technique, makes it an optimal method for the pathological diagnosis and treatment to avoid the cosmetic problems caused by external approach in limited paranasal sinus fibrous osseous lesions.

    Full Text Available The aetiology of fungal sinusitis is diverse and changing. Aspergillus species has been the most common cause for fungal sinusitis, especially in dry and hot regions like India. Trichosporon species as a cause for fungal sinusitis has been very rarely reported the world over. Here, we report a rare case of allergic fungal sinusitis caused by Trichosporon inkin in a 28-year-old immunocompetent woman. Bilateral nasal obstruction, nasal discharge and loss of smell were her presenting complaints. Diagnostic nasal endoscopy showed bilateral multiple polyps. Functional endoscopic sinus surgery was performed and many polyps were removed. Based on mycological and histopathological studies, the pathogen was identified as T. inkin.

    Between 1969 and 1985, 73 patients with maxillary sinus cancers underwent surgical excision and postoperative radiotherapy. The clinical stage distribution by the AJC system was 3T 1 , 16T 2 , 32T 3 and 22 T 4 . Six patients had palpable lymphadenopathy at diagnosis. Surgery for the primary tumor consisted of partial or radical maxillectomy, and if disease stage indicated it, ipsilateral orbital exenteration. This was followed by radiation treatment delivered through a wedge-pair or three-field technique. All but 3 patients received 50-60 Gy in 2 Gy fractions to an isodose line defining the target volume. Elective neck irradiation (ENI) was nor routinely given. Clinically involved nodes were treated with definitive radiotherapy (5 patients) or combined treatment (1 patient). Forty-five patients had no evidence of disease at the last follow-up. The 5-year relapse-free survival for the whole group was 51 percent. The overall local control rate was 78 percent, Patients with larger tumors, particularly if they also had histological signs of nerve invasion, had a higher recurrence rate than others. The overall nodal recurrence rate without ENI was 38 percent for squamous and undifferen-tiated carcinoma, and only 5 for adenoid cystic carcinomas. Therefore, the current recommendation is to deliver elective nodal irradiation routinely to patients with squamous or undifferentiated carcinoma, except for those who have T 1 lesions. Treatment complications were vision impairment, brain and bone necrosis, trismus, hearing loss, and pituitary insufficiency. The incidence of major side effects was determined by disease extent and treatment technique. Many technical refinements were introduced in order to limit the dose to normal tissues in an attempt to reduce the complication rate. To what extent such practice influences the outcome will be determined from subsequent analysis. (author). 23 refs.; 2 figs.; 5 tabs

    An incidental persistent falcine sinus was detected in an otherwise normal brain on MRI in a 12-year-old girl who underwent imaging after clinical suspicion of acute disseminated encephalomyelitis. The falcine sinus was associated with a hypoplastic posterior third of the superior sagittal sinus and a dominant straight sinus. Generally, atresia or hypoplasia of the straight sinus is associated with a persistent falcine sinus in postnatal life; otherwise, the falcine sinus disappears before birth. We discuss the embryological basis for such an association in this case. (orig.)

    An encephalocele is a protrusion of the cranial contents beyond the normal confines of the skull. It is a rare cause of seizure in adults. A 38-year-old woman presented with a first-onset seizure. Brain CT was interpreted as right frontal sinus opacification suggestive of sinusitis. The patient was discharged home with an amoxicillin prescription. A few days later, she was re-admitted with another seizure. Careful evaluation of the brain CT and MRI revealed a right frontal sinus posterior wall defect and possible brain encephalocele. The patient had complained of chronic nasal discharge for years and had also noticed a watery discharge from her right nostril. We suspected cerebrospinal fluid rhinorrhea. A bifrontal craniotomy was performed, the encephalocele was resected and cranialisation of the frontal sinus was completed. The patient remained free of seizures at the last follow-up. PMID:23188840

    Full Text Available Background. Thyroidectomy is one of the most frequently performed surgical procedures worldwide. Despite technical advances and high experience of thyroidectomy of specialized centers, it is still burdened by a significant rate of postoperative complications. Among them, the skin sinus formation is an extremely rare postthyroidectomy complication. Here, we first report the incidence of the skin sinus formation after thyroidectomy to identify the causes for skin sinus formation after thyroidectomy and to discuss its prevention and treatment options. Methods. A retrospective analysis was carried out of patients who underwent excision operation of fistula for postthyroidectomy skin sinus formation. Data were retrieved from medical records department of the Affiliated Hospital of Inner Mongolia Medical University. Results. Of the 5,686 patients who underwent thyroid surgery, only 5 patients (0.088% had developed skin sinus formation. All 5 patients successfully underwent complete excision of fistula. Conclusion. Infection, foreign body, thyroid surgery procedure, combined disease, and iatrogenic factors may be related with skin sinus formation after thyroidectomy. To reduce the recurrence of postoperative infections and sinus formation, intra- and postoperative compliance with aseptic processing, intraoperative use absorbable surgical suture/ligature, repeated irrigation and drainage, and postoperative administration of anti-inflammatory treatment are to be followed.

    Silas Antonio Juvencio de Freitas Filho

    2017-01-01

    Full Text Available Cholesterol granuloma (CG is a tissue reaction in response to the accumulation of cholesterol crystals rarely found in the maxillary sinus. The etiopathogenesis of maxillary sinus CG remains unclear. We reviewed the literature and added two new reports of cholesterol granuloma in maxillary sinus related to endodontically treated maxillary posterior teeth. The first report refers to a 45-year-old woman diagnosed with rhinitis, who was submitted to endodontic retreatment of maxillary molar, and subsequently showed maxillary sinus opacity with cystic appearance. The second case describes a young adult woman, who presented a cystic mass in maxillary sinus after endodontic treatment, in close association with the apex of the maxillary right second premolar. Both patients were treated by a classic Caldwell-Luc surgery and the microscopic analyses revealed maxillary sinus CG. In the following, the authors discuss the probable involvement of endodontically treated maxillary posterior teeth in the etiopathogenesis of maxillary sinus CG.

MATERIAIS E MÉTODOS: 49 pacientes submetidos à cirurgia endoscópica nasal, divididos em 3 grupos usando exclusivamente adrenalina tópica, nas concentrações de 1:2000, 1:10.000 e 1:50.000. Comparou-se o tempo operatório, o sangramento, as concentrações plasmáticas de adrenalina e noradrenalina e a variação dos parâmetros cardiovasculares. RESULTADOS: O tempo operatório por procedimento foi menor no grupo que utilizou adrenalina 1:2000, assim como o sangramento (p The ideal adrenaline concentration remains unknown. AIM: Compare topical adrenaline solutions in different concentrations. STUDY DESIGN: Prospective, double blind, randomized trial. PATIENTS AND METHODS: 49 patients divided in 3 groups underwent endoscopic sinus surgery, using only topical solutions of adrenaline in different concentrations (1:2,000, 1:10,000 and 1:50,000. We compared the duration of surgery, intra-operative bleeding, plasmatic levels of catecholamines, hemodynamic parameters and changes in heart rhythm. RESULTS: Surgery time was shorter in the group using adrenaline 1:2,000, which also showed less bleeding in all evaluations (objective and subjective - p < 0.0001. Plasmatic levels of epinephrine rose in all groups, more sharply in the 1:2,000 group. There was a trend towards elevation of blood pressure in the groups using adrenaline 1:2,000 and 1:10,000, with a greater occurrence of hypertensive peaks. DISCUSSION: We found a very significance bleeding difference favoring the 1:2,000. The blood pressure elevation in the 1:2,000 and 1:10,000 groups was progressive but very slow throughout the procedure, which could be associated with the anesthesia technique. CONCLUSION: We favor the use

    The emergence of minimally invasive endoscopic endonasal skull base surgery has necessitated reproducible and realistic simulators of rare vascular injuries. To assess the face and content validity of an innovative perfusion-based cadaveric model developed to simulate internal carotid artery (ICA) injury during endoscopic surgery. Otolaryngology and neurosurgery trainees attempted 3 consecutive trials of endoscopic control of a parasellar ICA injury, with standardized technical feedback. Time to hemostasis (TTH) and blood loss were trended. All participants completed validated questionnaires using a 5-point Likert scale to assess the domains of confidence gain, face validity, content validity, and curriculum applicability. Among all participants (n = 35), TTH and mean blood loss significantly decreased between first vs second attempt (P = .005), and first vs third attempt (P = .03). Following the first attempt, trainees experienced an average 63% reduction in blood loss and 59% reduction in TTH. In the quartile of most improved participants, average blood loss reduction was 1115 mL (84% reduction) and TTH of 259 s (84% reduction). There were no significant differences between trainees of varying postgraduate year or specialty. Average pre and postprocedural confidence scores were 1.38 and 3.16, respectively (P < .0001). All trainees reported model realism, which achieved mean face validity 4.82 ± 0.41 and content validity 4.88 ± 0.33. The perfusion-based human cadaveric ICA injury model achieves high ratings of face and content validity across all levels of surgical trainees, and enables safe, realistic simulation for standardized skull base simulation and future curriculum development. Objective improvements in performance metrics may translate to improved patient outcomes.

    Full Text Available Background: Due to the anatomical variations of the paranasal sinuses and its great importance in sinus surgery, as this area is in very close proximity to vital structures including the optic nerve, carotid artery, and skull base, anatomical knowledge of this area is of high importance. The purpose of this study is defining a full and clear impression of paranasal sinus anatomy and its variations as a model for the human population of the country. Materials and Methods: This study was conducted on 45 cadavers in Isfahan forensic Medicine center during 2010 to 2011. Nasal and paranasal sinuses endoscopic dissection was done with (zero and 30 o lenses (Olympus. The methods of performed dissection were via the Stamberger technique. Results: This study showed that 88.9% (40 cases of middle turbinates were in a typical form, while 6.7% (3 cases were in medial and only 4.4% (2 cases were in the lateral form. We also observed 88.9% (40 cases with Agger nasi cells, 37.8% (17 cases with Onodi cells, 28.9% cases with accessory Ostia of maxillary sinus (13 cases, and 15.6% of the cases (7 cases with concha bullosa.

    The type of pituitary adenoma with a manifestation that includes cavernous sinus syndrome is rare. Based on the clinical data of 70 patients, this study investigated the pathogenesis, imaging characteristics, and prognostic factors of pituitary adenoma with cavernous sinus syndrome. We conducted a retrospective analysis of the characteristics of patients with pituitary adenoma with cavernous sinus syndrome who received surgical treatment. The patients were classified into different prognosis groups according to the time required for them to recover from the cavernous sinus syndrome. Univariate analyses were conducted for the correlations between the prognosis and factors. Of the 3598 cases of pituitary adenomas, 70 (1.95%) presented cavernous sinus syndrome. Of the patients, 55.7% recovered within 2 weeks of surgery, 24.3% recovered from 2 weeks to 1 year after surgery, and 20% had not returned to normal after more than 1 year after surgery. Univariate analyses showed that shorter disease duration (P syndrome differs depending on the mechanism of the syndrome. There was no significant difference in the prognosis between patients with total pituitary adenoma resection and subtotal resection. Timely surgery within 100 days of symptom occurrence, Knosp grade 0-2, and associated pituitary apoplexy are predictive factors of good prognosis. Copyright © 2017 Elsevier Inc. All rights reserved.

We also included an in-depth literature review. Methods: We retrospectively reviewed the medical files of 51 patients from January 2008 to January 2014. The records were evaluated for age, gender, type of orbital complications, symptoms, predisposing factors, imaging studies, medical and surgical management, culture results, and follow-up information. SPSS version 15.0 software (Statistical Analysis, The Statistical Package for Social Sciences Inc, Chicago, IL was used for the statistical analysis. Results: Fifty-one patients met the criteria, with available medical records, for the study (29 male, 22 female. Thirty-two (62.7% were diagnosed with preseptal cellulitis and 19 (37.3% with postseptal cellulitis. After a detailed evaluation, 15 were diagnosed with a subperiosteal abscess (SPA, and 4 were diagnosed with orbital cellulitis. The age and gender was similar for the two groups. Five patients with medial SPA were treated with endoscopic sinus surgery, one patient with inferior SPA was treated with external surgery, and six patients with other localizations were treated with a combination of endoscopic sinus surgery and external surgery. All patients presented with periorbital erythema and edema. The length of hospitalization and duration of symptoms were similar in both groups. Visual acuity was between 1/10 to 10/10 (mean 7/10 and statistically significant for preseptal and postseptal cellulitis groups (p<0.001. All patients received intravenous antibiotics upon the first day of admission. Conclusion: Orbital complications of acute sinusitis required intensive follow-up and a multidisciplinary approach. A contrast-enhanced paranasal sinus computerized tomography (CT scan can detect the extent of the infection. An initial trial of intravenosus (IV antibiotics may be appropriate when

    Full Text Available Placing dental implants in the maxillary posterior region can be both challenging and un-nerving for a regular implant dentist who is not well versed with advanced surgical procedures. It is vital for a general dentist to understand the fundamentals of bone grafting the maxillary sinus if he/she is really committed to providing the best health care for their patients. The dental practice is seeing an increasing group of patients who are living longer, and this group of older baby boomers often has an edentulous posterior maxilla either unilateral or bilateral. When edentulous, the posterior maxilla more likely has diminished bone height, which does not allow for the placement of dental implants without creating additional bone. Through grafting the maxillary sinus, bone of ideal quality can be created (allowing for placement of dental implants, which offer many advantages over other tooth replacement modalities. The sinus graft offers the dental patient a predictable procedure of regenerating lost osseous structure in the posterior maxilla. This offers the patient many advantages for long-term success. If dentists understand these concepts, they can better educate their patients and guide them to have the procedure performed. This article outlines bone grafting of the maxillary sinus for the purpose of placing dental implants. This review will help the readers to understand the intricacies of sinus augmentation. They can relate their patient's condition with the available literature and chalk out the best treatment plan for the patient, especially by using indirect sinus augmentation procedures which are less invasive and highly successful if done using prescribed technique.

  12. MRI of maxillary sinuses

    A mucous membrane of the maxillary sinus is clinically important in the dental fields. Magnetic resonance imaging (MRI) can demonstrate a mucous membrane because the mucosa contains rich free water. However, the morphology and location of the mucous membrane of normal maxillary sinuses have not been studied well by MRI. T2-weighted coronal images were obtained by spin echo technique in 40 normal volunteers. The eight maxillary sinuses were classified into four groups (Type 1∼IV) according to the morphology and also classified into five groups (Type a, b1, b2, b3, c) according to the location of the mucous membrane. Coronal images obtained at a standard angle of 77 degree to the Frankfort horizontal (FH) plane was the best for the evaluation of maxillary sinus because the image displayed the maximum cross-section of the maxillary sinus. In the normal cases, Type I (no high signal intensity) was observed in 20 sites, Type II (linear high signal intensity) in 48 sites, Type III (belt-like high signal intensity) in 11 sites and Type IV (mass-like high signal intensity) in 1 site. Type a (medial∼basal wall) was observed in 46 sites, Type b1 (medial wall alone) in 4 sites, Type b2 (basal wall alone) in 8 sites and Type c (entire wall) in 2 sites. Half of the cases showed the same findings bilaterally. Thus, MRI could demonstrate the morphology and location of the mucous membrane in the normal maxillary sinus so clearly that MRI was considered to be a useful diagnostic tool in the dento-maxillo-facial region.

    1995-01-01

    Only recently management of benign as well as malignant nasal and paranasal sinus tumours by endoscopy, including endoscopic removal, has been introduced. The most important contribution of the endoscope in the management of these tumours is diagnostic, primarily as well as during follow-up. Although, in general, endoscopic sinus surgery has many advantages over classical external surgery, disadvantages are present when tumours are concerned. Some agreement already exists on the role and limitations of endoscopic sinus surgery in benign tumours, but in malignant processes usually more mutilating procedures are needed and only in selected cases might endoscopic removal be used.

    The CT scores and scoring for improvement based on them, which we proposed previously, is a simple and highly reproducible method of evaluation of sinus units before and after an operation for chronic sinusitis. We compared this evaluation method with the results of quantitative assay and showed its advantages and disadvantages. The subjects were 258 sinuses in patients who underwent endonasal sinus surgery (ESS) in the department of otolaryngology, Kyoto Prefectural University of Medicine Hospital from April 1996 to April 1997. The subjects were evaluated according to the following 4 grades negligible shadow in the paranasal sinus CT scored 0, less than 50% shadow scored 1, more than 50% of shadow scored 2, and mostly filled with shadow scored 3. Furthermore, the preoperative and postoperative CT scores were compared and the rate of improvement was rated in the following 3 grades: score 0 for unchanged or aggravated subjects, score 1 for subjects showing improved CT score by 1 grade, and score 2 for those showing improved CT score by 2 grades or a postoperative CT score of 0. Quantitative image analysis was input into a personal computer and the ratio occupied by the shadow was calculated, as the shadow ratio. While some discrepancies were seen in parts in the comparison of the quantitative image analysis and CT scores as the former captures minute shadows, a positive correlation was obtained overall. Attention is needed to accurately evaluate small paranasal sinuses such as the frontal sinus, and small amounts of shadow, which are areas where errors may occur. A satisfactory correlation was obtained between the score for the improvement rate and the difference in the shadow ratios before and after surgery. The CT scores and the scores for the improvement rate showed no difference from the results of other evaluation methods reported in the past, and evaluation of similar precision was possible. It was thought that this simple evaluation method of CT findings in

    Objective: To study a rare CT finding of pulsatile tinnitus (PT) caused by sigmoid sinus abnormalities. Methods: The imaging data of PT caused by sigmoid sinus abnormalities were analyzed retrospectively in 15 patients (15 female). The median age was 45 years (24 to 63 years). The duration of persistence pulsatile tinnitus was from 0.5 year to 36.0 years (median time, 2.0 years). The tinnitus was at left side in 5 patients and right side in 10 patients. Fifteen patients underwent HRCT of the temporal bone. Of them, 12 patients underwent cerebral CT angiography and CT venogram (CTA/CTV), and 9 patients underwent cerebral digital subtraction angiography (DSA). Nine patients underwent transmastoid reconstruction surgery of the sigmoid sinus. Of them, the tinnitus was at left side in 2 patients and right side in 7 patients. Paired rank sum test was used to compare the cross-sectional area of the sigmoid sinus of the tinnitus side and normal side.Results: On HRCT, foca bony coarse defect is shown in the anterior sigmoid wall in 11 patients and anterolateral sigmoid wall in 4 patients. On CTA/CTV, the sigmoid sinus focally protuded into the adjacent mastoid air cells and formed diverticulum in 10 patients. The pulsatile tinnitus disappeared immediately after transmastoid reconstruction surgery of the sigmoid sinus in all 9 patients. The cross-sectional area of the sigmoid sinus of the tinnitus side was 100.6 (41.5-96.2)mm 2 , it was 77.0 (92.1-122.4)mm 2 in the nonmal side (Z=2.158, P=0.031). Conclusion: Focal bony defect of the sigmoid wall with sigmoid sinus diverticula is one of the causes which lead to pulsatile tinnitus, which can be easily identified by imaging examination.

    The abducens nerve, cranial nerve VI (CNVI), is the medial-most nerve in the cavernous sinus. Its close proximity to the sphenoid sinus makes it susceptible to injury, invasion, or compression from a sphenoid pathology leading to horizontal gaze diplopia. A wide range of literature describes myriad causes for CNVI palsy, but there is a lack of references that point to paranasal sinus pathology as an etiology, as well as the prognosis and timeline for resolution. Here, we describe a series of patients that presented with CNVI palsy, their management, and prognosis for recovery. This study was designed to evaluate and understand prognostic factors predicting disease course and likelihood of resolution in patients with abducens nerve palsy. A multi-institutional retrospective review was performed of all patients presenting with CNVI palsy between 2009 and 2012. The demographic data, radiological features, treatment regimens, and disease courses were analyzed. Fifteen patients at four institutions were identified. Seven patients had neoplasms originating from the paranasal sinuses, three suffered from allergic fungal sinusitis, three patients had invasive fungal sinusitis, one patient had fibrous skull base dysplasia, and one had chronic bacterial sinusitis. The average follow-up time from presentation was 9 months (range, 1-16 months). Thirteen patients underwent surgery, three received chemotherapy, and four had radiation therapy. CNVI palsy resolved in 50% of the cases, with an average time to resolution of 6 weeks (range, 2-12 weeks). Paranasal sinus pathology is a rare cause of CNVI palsy. A number of factors may help to predict prognosis in these patients. Masses compressing, but not destroying or invading, the cavernous sinus had optimal posttreatment outcomes with full resolution occurring as early as 2 weeks. Destructive lesions that invaded CNVI and its vasculature, i.e., invasive fungus, were negative indicators for recovery. Knowledge of factors that affect

    Full Text Available Statement of Problem: Variation in paranasal sinus anatomy as shown on computed tomographic scans is of potential significance for it may pose risks during surgery or predispose to certain pathologic conditions.Purpose: The aim of this study was to assess the relative frequency and concurrence of variations in paranasal sinus anatomy in a given population and to compare the results with previous investigations conducted on different populations.Materials and Methods: All patients over 16 years of age referred to Valiasr hospital,Tehran, Iran, with paranasal sinus tomographic scans and a clinical diagnosis of chronic sinusitis were considered for this study. After excluding those with altered anatomy(iatrogenic or pathologic, scans of unaltered patients were meticulously analyzed for variations in sinus anatomy. Findings were recorded on the patient’s data sheet. The distance between the maxillary sinus floor and the alveolar ridge at the level of the 1stmolar was recorded. All findings were analyzed, and tested with Chi square, where applicable.Results: Overall 143 patients were analyzed (48.3% male and 51.7% female. The frequency of major sinus variations was: Agger nasi cell in 56.7%, Haller cell in 3.5%,Onodi cell in 7%, nasal septal deviation in 63%, Concha bullosa in 35%, and dental anomalies in 4.9% of the studied cases. The distance between the upper alveolar ridge and maxillary sinus floor was 0-30mm (mean 12.16 on the right, and 0-52mm (mean 12.20 on the left.Conclusion: The frequency of anatomic variations in sinus anatomy may be related to race and heredity. A lower number of cases in addition to the use of low yield imaging may explain the discrepancies observed between our results and other investigations.The findings of the present study were based on computed tomography.

    Anatomic variations of paranasal sinuses are common findings in daily practice. For a radiologist, to know these variations is necessary because of the pathological conditions related to them, and also because they are import for planning a functional endoscopic endonasal surgery, the procedure of choice for diagnosis, biopsy and treatment of various sinonasal diseases. To assure that this surgery is done safely, preventing iatrogenic injuries, it is essential that the surgeon has the mapping of these structures. Thus, a CT is indispensable for preoperative evaluation of paranasal sinuses. Since a general radiologist is expected to know these changes and their relationship to pathological conditions, a literature review and a iconographic essay were conducted with the aim of discussing the importance of major anatomic variations of paranasal sinuses.

    Full Text Available Purpose: The aim of this study was to determine the prevalence and location of maxillary sinus septa with the help of dental volumetric tomography. Methods: 760 patients’ 1520 maxillary sinus were evaluated by dental volumetric tomography for detecting maxillary sinus septa. Maxillary sinus was divided into 3 zones (anterior, middle and posterior zones while location of the maxillary sinus septa. Results: 47 of maxillary sinus septa existed in the anterior zone (24.7%, 35 of them in the middle zone (18.4% and 108 of them in the posterior region (56.8%. Conclusion: The formation of the maxillary sinus septa was affected by the existence or lack of the teeth. Correct detection of the presence of maxillary sinus septa was important prior to sinus lifting and dental implant surgery. Dental volumetric tomographical evaluation of maxillary sinus septa was more useful for a correct diagnosis and treatment planning. [Cukurova Med J 2013; 38(3.000: 467-474

    We assessed the morphological and radiological characteristics of ethmomaxillary sinus (EMS), which is an enlarged posterior ethmoidal air cell occupying the superior portion of the maxillary sinus while draining into superior meatus. This study is based on 1450 patients submitted to CT examination of the paranasal sinuses between 1998 and 2002. Sequential CT scans were obtained in the coronal plane in all the patients with 2.5- to 5-mm section thickness and were evaluated for EMS. The diagnosis of EMS was made when there was a posterior ethmoidal cell occupying the superior part of the maxillary sinus while draining to the superior meatus. When EMS was diagnosed, the morphology of the septum between the and maxillary sinus, and width of the superior meatus, were noted. The EMS was found in 10 of 1450 (0.7%) patients. The coexisting anatomic variations were concha bullosa (50%), upper concha pneumatization (20%), maxillary sinus hypoplasia (20%), uncinate bulla (10%), hypertrophied inferior concha (10%), paradoxic middle concha (10%), and septate maxillary sinus (10%). There was no relation between EMS and sinus disease. The EMS is a rare anatomic variation and does not appear to be associated with sinusitis. The EMS is not a well-studied anatomic variation, and the literature is lacking adequate information about this anatomic variation. This study performed in a large series of patients will possibly contribute to better understanding of this particular anomaly. (orig.)

    Objective: To explore the relation between venous sinus stenosis and pseduotumour cerebri and to discuss the efficacy and strategy of venous sinus stenting for its treatment. Methods: Venous sinus stenting was performed in a total of 9 patients with pseudotumour cerebri accompanied by dural sinus stenosis. The clinical data, including the clinical presentations, intracranial pressure, angiographic findings, pressure of dural sinus,methods of treatment and the therapeutic results, were retrospectively analyzed. Results: Bilateral disc edema was seen in all patients. The pressure gradient in the lateral sinuses was obviously high before stenting (22.67±7.25)mmHg in all patients and a reduction in intra-sinus pressure and pressure gradient was also found (5.78±3.77)mmHg. The symptoms associated with intracranial hypertension were gradually improved or disappeared in two weeks after the placement of the stent in all cases, and the intracranial pressure dropped evidently (12.78±5.97)cm H 2 O. Vision was improved in 7 cases at three months, whereas it remained poor in 2 cases despite normalized intracranial pressure. There was no other permanent procedure-related morbidity. The patients were followed up for 3 months to 5 years, and no recurrence developed. Conclusion: Lateral sinus stenting is an effective method for the treatment of pseudotumour cerebri with dural sinus stenosis. (authors)

    2013-06-01

    Full Text Available Introduction: Ectopic tooth eruption may result owing to one of 3 processes: developmentalDisturbance, iatrogenic activity, or pathologic process, such as a tumor or a cyst. In rare cases, occlusion of the sinus ostia may predispose a patient to develop a maxillary sinus mucocele. When the maxillary sinus is invaded, symptoms usually occur late in the process.   Case report: A 17 years old boy referred to department of Otolaryngology, Head and Neck Surgery of university of medical sciences, Tabriz_Iran in 2010 with chronic recurrent mucoprulent discharge from retromollar trigone , posterior to right superior alveolar ridge. CT scan revealed a dense mass resembling tooth, obstructing sinus ostium with homogenous opacity with ring enhancement, occupying whole sinus and expanding all walls. A Caldwell Luke approach in combination with endoscopy was selected.   Discussions: In the present patient, removal of ectopic tooth resolved the symptoms completely, the fistula obstructed and discharges discontinued. An ectopic tooth is a rare entity obstructing sinus ostium. The etiology of ectopic eruption has not yet been completely clarified, but many theories have been suggested,including trauma, infection, developmental anomalies and pathologic conditions, such as dentigerous cysts. In summary, although the ectopic teeth is rare but it would be assumed in presence of unilateral symptoms of sinonasal cavity. Therefore in peristant unilateral sinonasal symptoms we should complete examining of this site to rule out rare causes of these symptoms.

    Consideration of the causes of unilateral paranasal sinusitis, which frequently occurs in routine medical care and is often associated with odontogenic infection. Retrospective data analysis. A review of the charts of all 190 patients treated for unilateral paranasal sinusitis at our department between 2005 and 2012 was carried out. All patients were diagnosed based on clinical signs, symptoms, and imaging findings, including computed tomography (CT), orthopantomography (OP), and other modalities. Patients were classified in three groups: patients with odontogenic infection involvement (Group A); patients without odontogenic infection involvement (Group B); and patients with inconclusive odontogenic infection involvement (Group C). The most common cause of unilateral paranasal sinusitis was odontogenic infection, as seen in 138 cases (72.6%), followed by chronic inflammation in 43 cases (22.6%). Among patients diagnosed with odontogenic infection, one patient was also diagnosed with coexistent polyps and mycosis. Based on CT, OP, EPT, and oral examination, final distribution was 138 patients (72.6%) in Group A, 32 (16.8%) in Group B, and 20 (10.5%) in Group C. Odontogenic infection involvement was implicated in approximately 70% cases of unilateral paranasal sinusitis. Odontogenic maxillary sinusitis can be difficult to diagnose, and consideration of imaging performed under various conditions is recommended. In order to determine the most appropriate treatment for unilateral paranasal sinusitis, whether such treatment will be surgery, dental treatment, conservative therapy, or other treatments, collaboration between concerned doctors is essential.

    Radiography and endoscopy of a 17-day-old Standardbred foal that had right-sided facial swelling and dyspnea since birth revealed a soft tissue mass in the right nasal passage and right maxillary and frontal sinuses. A bone flap was used to expose the mass, and a fluid-filled structure was removed surgically. After surgery, the dyspnea was alleviated. The facial deformity resolved by the time the foal was 6 months old. The upper airway obstruction was absent clinically and endoscopically by the time the foal was 17 months old

    Proptosis due to intraorbital process is frequent and secondary to various aetiologies. Its findings in ENT practice is the sign of a serious complication. The purpose of this study is to review a series of patients who presented an exophtalmy. We conducted a retrospective analysis of 15 patients with exophthalmos complicating a rhinosinusal benign disease, diagnosed and treated in our department between January 2003 and December 2010. As their management is different, we excluded all cases of orbital cellulitis. Average age of presentation was 38 years, without sex predominance. Exophthalmos was unilateral, non axial and irreductible in all cases. The average duration of symptoms installation was 18 months. The most common aetiology was fronto-ethmoidal osteomas (9 cases), followed by fronto-ethmoidal mucoceles (5 cases) and spheno-orbito-frontal fibrous dysplasia (1 case). The functional prognosis of the affected eye depended on the aetiology and the degree of ocular injury. In our experience, sinusal causes of exophthalmos comprise osteomas and ethmoidal mucoceles. Medical history, clinical and radiological data as provide the diagnostic. In case of benign tumours, surgery is the curative treatment.

    Objective: To investigate the application value of multi-slice spiral CT on the congenital malformation of coronary sinus. Methods: MSCT finding of 98 patients with coronary sinus malformation confirmed by surgery were retrospectively analyzed,and the cases were divided into four categories based on the Mantini theory and comparison was made between the diagnosis from ultrasound and CT. A 2 × 2 table for Chi-square test was also used for statistics analysis. Results: Among 98 patients,there were 72 patients with persistent left superior vena cava reflowed to right atria through coronary sinus, with 48 patients diagnosed by ultrasound and 72 patients by MSCT; there were 13 patients with anomalous pulmonary venous connection to coronary sinus, with 12 patients diagnosed by ultrasound and 13 patients by MSCT diagnosis; there were 10 patients with unroofed coronary sinus syndrome, with 6 patients diagnosed by ultrasound and 8 patients by MSCT, there were 2 patients with coronary sinus atresia, all diagnosed by MSCT; there were 1 patient with coronary sinus anomaly reflow to left arita. The significant difference between 2 modalities (χ 2 =22.7, P<0.01) shows that CT is superior to ultrasound. Conclusion: MSCT is much more better than ultrasound in the diagnosis of malformation of coronary sinus and it can provide reliable diagnosis prior to surgery or interventional therapy. (authors)

    Intrasinus new bone formation (BF) has been observed after no-grafting osteotome sinus augmentation, and it is hypothesized to be influenced by the dimensions of the maxillary sinus. The aim of this clinical trial is to evaluate the influence of lateral-medial sinus width (SW) on no-grafting osteotome sinus augmentation outcomes using cone-beam computed tomography. All patients recruited for this prospective study were treated with no-grafting osteotome sinus augmentation with simultaneous implant placement. Cone-beam computed tomography was obtained before, immediately after, and 6 months after the surgical procedure to use for measurements. Descriptive statistics were calculated and univariate, bivariate, and multivariate analysis were conducted to evaluate the influence of average SW and other relevant factors on procedure outcomes, including new BF, residual bone resorption (BR), and change of peri-implant bone height (CPBH). A total of 48 implants placed in 32 elevated sinuses of 29 patients were included. The average SW was 11.3 ± 1.8 mm. Intrasinus BF measured 1.7 ± 0.9 mm at 6 months after surgery. The amount of BR was 0.3 ± 0.9 mm, and CPBH was calculated as 1.3 ± 1.3 mm. Multivariate analysis showed a negative correlation between SW and BF (r = -0.469, P = .001), as well as between SW and CPBH (r = -0.562, P = .001). A positive correlation was discovered between SW and BR (r = 0.311, P = .027) in general. The lateral-medial SW was observed to have a negative correlation with new BF and CPBH after no-grafting osteotome sinus augmentation.

    Full Text Available The exposing of dental implant into the maxillary sinus combined with membrane perforation might increase risks of implant failure and sinus complications. Objective: The purpose of this study was to investigate the effects of the dental implant penetration into the maxillary sinus cavity in different depths on osseointegration and sinus health in a dog model. Material and Methods: Sixteen titanium implants were placed in the bilateral maxillary molar areas of eight adult mongrel dogs, which were randomly divided into four groups according to the different penetrating extents of implants into the sinus cavities (group A: 0 mm; group B: 1 mm; group C: 2 mm; group D: 3 mm. The block biopsies were harvested five months after surgery and evaluated by radiographic observation and histological analysis. Results: No signs of inflammatory reactions were observed in any maxillary sinus of the eight dogs. The tips of the implants with penetrating depth of 1 mm and 2 mm were found to be fully covered with newly formed membrane and partially with new bone. The tips of the implants with penetrating depth over 3 mm were exposed in the sinus cavity and showed no membrane or bone coverage. No significant differences were found among groups regarding implant stability, bone-to-implant contact (BIC and bone area in the implant threads (BA. Conclusions: Despite the protrusion extents, penetration of dental implant into the maxillary sinus with membrane perforation does not compromise the sinus health and the implant osseointegration in canine.

  1. Successful endoscopic management with Mitomycin C application for sinusitis with orbital cellulitis

    2013-01-01

    Full Text Available Background: Sinusitis with orbital complication is a potentially fatal disease that has been known since the days of Hippocrates. Primary sinus infection is the most common cause of orbital cellulitis. It is an emergency that threatens not only vision but also life from complications such as meningitis, cavernous sinus thrombosis, and brain abscess. Surgical intervention is mandatory whenever antibiotic treatment fails. There are two surgical options for the drainage, an external approach via a Lynch incision and an intranasal endoscopic procedure. Materials and Methods: Five patients with orbital cellulitis secondary to acute on chronic rhinosinusitis were included in the study from the period of 2010 - 2011. All five patients did not respond to medical management and hence underwent endoscopic sinus surgery with treatment of orbital pathology. At the end of the surgical procedure Mitomycin C in a concentration of 0.4mg/ml was applied with a cottonoid for a period of 4 minutes to prevent chance of adhesion formation. Results: In this series 3 females and 2 male patient with orbital cellulitis secondary to acute on chronic rhinosinusitis underwent endoscopic sinus surgery with treatment of orbital pathology. All 5 patients showed subjective and objective improvement within one week of endoscopic management. Conclusion: Though antibiotics have altered the course of sinusitis, its grave complications still persist in our environment. The excellent results and the absence of any major complications of endoscopic sinus surgery and drainage of abscess with application of Mitomycin C can be recommended as the preferred surgical technique.

    To determine whether the wall thickening of the maxillary sinus is a characteristic finding in aspergillosis. In 103 patients, including 26 with aspergillosis, 21 with inverted papilloma (IP), and 56 with unilateral chronic sinusitis, the thickness of the maxillary sinus wall was determined by CT scanning. All cases were proven pathologically, and patients with a history of previous surgery of bone destruction were excluded. Two neuroradiologists retrospectively reviewed the CT scans using bone window settings for sinus wall hyperostosis and the presence of intrasinus calcification. Thickening of the maxillary sinus wall was assessed visually in a semiquantitative manner, and graded as 'none' (absence of thickening), 'mild' (thickening of up to 1.5 times), or moderate ot severe(over 1.5 times thicker than normal contralateral sinus wall at its thickest point). Moderate to severe wall thickening was found only in patients with aspergillosis (21/26, 80.8%). Mild wall thickening was seen in two patients with aspergillosis (2/26, 7.7%), in 12 of 21 with IP (57.1%), and in 5 of 56 with chronic maxillary sinusitis (8.9%). Most cases of chronic maxillary sinusits( 51/56,91.1%), 9/21 IP cases (42.9%), and 3/26 cases of aspergillosis (11.5%) showed no thickening of the maxillary sinus wall. Calcifications were found in 18 patients with aspergillosis (69.2%), in no patient with IP (0%), and in one with chronic maxillary sinusitis (1.8%). We suggest that 'moderate to severe' wall thickening of the maxillary sinus is the characteristic finding of aspergillosis. Although various sinonasal diseases can cause bone change, CT findings of hyperostosis of the maxillary sinus and intrasinus calcification are very helpful in differentiating fungal sinusitis from other types of chronic inflammatory lesions.

    Elderly patients frequently suffer from dizziness and syncope; however, an underlying disease may not always be identified. Three patients aged 69, 71 and 56, respectively, experienced spells of dizziness and syncope. Massage of the carotid sinus demonstrated the presence of a carotid sinus syndrome (CSS), an abnormal baroreflex response of the carotid sinus that leads to asystole and extreme hypotension. Conventional treatment is generally by insertion of a pacemaker. These patients, however, were referred to the vascular surgery department of our hospital for removal of adventitial layers of proximal portions of the internal carotid artery. Recovery was uneventful; all three are now free of symptoms. CSS should be considered in the differential diagnosis of dizziness and syncope. Surgical denervation of the carotid artery is a valid treatment option, especially in the vasodepressive or mixed type of CSS.

    Aspergillosis of the maxillary sinuses shows an increasing incidence in even otherwise healthy patients. Next to inhalation as the mode of infection, a dental root canal filling with an orosinusal fistula can be the cause. As most infections remain initially undetected or underestimated as common sinusitis, early diagnosis must be achieved. Standard X-ray of the paranasal sinuses, conventional tomography as well as CT scans are of major importance. Centrally located hyperdense opacifications are a good criterion and can be best seen in CT. Even when the case has not progressed too much, radical surgery combined with Amphotericin B therapy is still the treatment of choice since the infection may progress rapidly. (orig.).

    Myxoma is a slow growing, benign neoplasm, which pathogenesis still remains disputed. The lesion has well-defined borders but a true capsule is absent. Because of that myxoma can be locally invasive causing bone destruction. A change is mainly observed among persons between 20-30 years of age and is very uncommon in the pediatric population. Most myxomas are observed in myocardium, but rarely may also manifest in the head and neck region. In the paper we describe an unusual case of myxoma of maxillary sinus in a female infant. Diagnostic challenges, treatment, outcome, post-operative follow-up are discussed as well as a review of the literature in order to present many features of this rare pathology. © 2016 MEDPRESS.

    Aggressive fibromatosis (AF) is a benign tumour with expansive and locally invasive growth. It is very rarely seen in the head and neck area. We present a 52-year-old female patient with AF localized to the left frontal sinus. The condition was initially mistaken for chronic sinusitis however...... computed tomography indicated tumour. A biopsy showed AF and the patient received surgical treatment. Symptoms, signs and treatment are discussed. It is concluded that AF in the sino-nasal tract is a rare, but potentially life threatening condition which might be mistaken for a simple sinusitis...

    Full Text Available The purpose: to prove diagnostic capabilities of modern radiation techniques in odontogenic maxillary sinusitis. Material and methods: The study involved 546 patients with sinusitis. The following methods have been used: X-ray of the paranasal sinuses, contrast maxillary sinus radiography, contact intraoral radiographs, orthopantomography, computer tomography and magnetic resonance imaging. Results. In 7,9% of cases the presence of odontogenic sinusitis has been established, in 92,1 % rhinogenous sinusitis has been revealed. The work provides information about the effectiveness of various radiation techniques in the diagnosis of odontogenic sinusitis. Conclusion. For suspected odontogenic sinusitis, treatment of choice includes the combined use of X-ray of the paranasal sinuses in the mentoanterior projection and contact intraoral radiographs of «causal teeth». Computer tomography is the most informative additional method to clarify the diagnosis of odontogenic sinusitis.

    A two-part study using medium field strength magnetic resonance imaging (MRI) was designed to describe normal paranasal sinus development and to prove preliminary criteria for clinical sinus disease. In part 1 of the study the paranasal sinuses were retrospectively evaluated in 80 infants and children aged 0-17 years undergoing brain MRI for indications both unrelated and related to sinus disease. MRI criteria were developed for independent grading of paranasal sinus development and 'anatomical' sinus disease, i.e., diseases as seen by the radiologist. The variability was in extent quantified of sinus pneumatization (a measure of sinus development) in infants and young children. Part 2 was a double-blind prospective study in 21 patients to correlate 'anatomical' disease with 'clinical' sinus disease. In this limited preliminary study, clinical sinus disease was only seen in the patients with moderate or severe anatomical disease (sensitivity 100 percent; specificity 100 percent).

    Endoscopic sinus surgery (ESS) including middle meatus antrostomy (MMA) has been advocated as the technique of choice in the treatment of maxillary chronic odontogenic sinusitis (COS). However, recently the endoscopic canine fossa puncture (CFP) has been proposed as an alternative surgical technique of accessing the entire antrum when pathology is limited only to the maxillary sinus. This study was designed to assess the outcomes of the CFP approach versus ESS (comprising MMA) in the management of COS. A prospective study was performed on patients with COS produced by odontogenic infections (periapical granulomas or small inflammatory cysts of the molars or bicuspids), oroantral fistula (OAF), large odontogenic cysts, and maxillary foreign bodies (dental fillings, teeth roots, and implants). Patients were randomly allocated into two groups: 56 patients underwent CFP and in 54 patients the maxillary sinus was approached through MMA. After a mean follow-up of 18.5 months, recurrence rates were compared between the two groups. During the follow-up period, OAF recurred in 10 patients: 4 in the MMA group (7.4%) and 6 in the CFP group (10.7%). The difference is not statistically significant (p = 0.39, Fisher exact test). In patients with COS a conservative approach with avoidance of endonasal surgery is suggested: in COS without a fistula, CFP at the time of dental treatment will be sufficient. In OAF cases, CFP yielded similar results with MMA. Nevertheless, additional study with a larger sample and a longer follow-up is required to validate these results.

    The authors report 14 cases of Wegener granulomatosis in which one or more paranasal sinuses were obliterated by bone. The maxillary antra were involved in all cases, with the other sinuses being affected less frequently. These changes are thought to result from chronic bacterial sinusitis superimposed on the granulomatous vasculitic process. Computed tomography dramatically demonstrated the bone changes, consisting of a combination of sinus wall thickening and trabeculated new bone formation within the sinuses.

    Filling defects of dural venous sinuses are considered to be a challenging problem especially in case of symptomatic patients. Many lesions have to be ruled out such as sinus thrombosis, arachnoid granulations and tumours. Encephalocele into dural sinus is also a rare cause of these filling defects of dural sinuses. Here, we report an extremely rare case with spontaneous occult invagination of temporal brain tissue into the left sigmoid sinus and accompanying cerebellar ectopia. PMID:24311424

    The purpose of this study was to evaluate the augmentation volume of a sinus graft according to the time and graft materials based on cone-beam computed tomography (CBCT) scans and to assess efficacy of a bioabsorbable membrane. Fourteen patients were investigated, and volumetric analysis was performed using OnDemand 3DTM software (Cybermed, Seoul, Korea). CBCT scans were performed on patients before surgery, immediately after surgery, 6 months after surgery, and 1 year after surgery. Following this analysis, the volumetric data were compared with the actual grafted volumes. Bioabsorbable membranes were used in all patients to promote the protection of sinus membranes and to guide bone regeneration. Overall, the average percent volume of graft material that remained 6 months after implantation was 82.0%, and the average percent volume of graft material that remained 1 year after surgery was 60.4%. These reductions in the volume of graft material from immediately after surgery until 6 months or 1 year after surgery were shown to be statistically significant (P = 0.002 and P volumetric analysis performed using CBCT can provide highly accurate data. A significant difference was observed in volumetric change over time, but no significant differences were observed between materials. No significant relationship was observed between the resorption of grafted bone and the success rate.

  19. Complications of pediatric paranasal sinusitis

    Energy Technology Data Exchange (ETDEWEB)

    2004-12-01

    Acute paranasal sinus infection in children is often diagnosed clinically without the need for radiographic confirmation. Most cases have a favorable outcome following appropriate antibiotic therapy. A small percentage of cases where symptoms and signs are persistent or severe will require emergent imaging to rule out complications related to local spread of disease intraorbitally or intracranially. A strong index of suspicion is required in such cases, and cross-sectional imaging evaluation with CT and MRI should include axial and coronal images of the paranasal sinuses and, where appropriate, the orbits and brain (with attention to the cavernous sinus). There is no role for plain radiography in the evaluation of the complications of acute sinusitis in the pediatric patient. (orig.)

  20. The role of proper treatment of maxillary sinusitis in the healing of persistent oroantral fistula

    Directory of Open Access Journals (Sweden)

    David B. Kamadjaja

    2008-09-01

    Full Text Available Background: Oroantral communication (OAC is one of the possible complications after extraction of the upper teeth. If not identified and treated properly, a large OAC may develop into oroantral fistula (OAF which means that there is a permanent epithelium-lined communication between antrum and oral cavity. Such fistulas may cause ingress of microorganism from oral cavity into the antrum leading to maxillary sinusitis. Oroantral fistula usually persists if the infection in the maxillary antrum is not eliminated. Therefore, treatment of oroantral fistula should include management of maxillary sinusitis in which surgical closure of oroantral fistula should be done only when the sinusitis has been cured. Purpose: This case report emphasizes on the importance of proper management of maxillary sinusitis in the healing of oroantral fistula. Case: A case of an oroantral fistula following removal of upper left third molar is presented. As the maxillary sinusitis was not identified pre-operatively, two surgical procedures to close the fistula had ended up in dehiscence. Case management: The diagnosis of maxillary sinusitis was finally made and the sinusitis subsequently treated with combination of trans-alveolar sinus wash out, insertion of an acrylic splint, and two series of nasal and sinus physiotherapy procedures. The size of the defect decreased gradually during the treatment of the sinusitis and finally closed up without any further surgical intervention. Conclusion: This case report points out that it is important to detect intraoperatively an antral perforation after any surgery of the maxillary teeth and to close any oroantral communication as early as possible and that it is important to treat properly any pre-existing maxillary sinusitis before any surgical method is done to close the fistula.

    Full Text Available Background: Interventions involving the middle meatus are commonly performed because the majority of the paranasal sinuses open into the osteomeatal complex. Therefore, the aim of the present study was to locate the level of maxillary sinus ostium (MSO, to measure the distances between MSO and different anatomical landmarks, to measure the different dimensions of maxillary sinus and to compare the morphology of maxillary sinus between the right and the left sides. Materials and Methods: The study involved 50 computed tomography (CT images of normal paranasal sinus anatomy in coronal and sagittal planes from the Department of Radiodiagnosis. The location of the sinus ostium (upper, middle, or lower third was observed. Perpendicular distance from the sinus ostium to the lower border of inferior turbinate and hard palate were measured. The maximum vertical, transverse, and antero-posterior diameters of the maxillary sinus were measured. Results: Of 50 CT images, the MSO was located in the upper third in 40 cases while in 10 it was located in the middle third. The most common location of MSO was in the upper third. The dimensions of the maxillary sinus indicated bilateral symmetry. Conclusion: The dimensions of the maxillary sinus indicated bilateral symmetry, and there were no significant gender differences when compared. However, the distances of the MSO from the major anatomical landmarks were significantly different between males and females which are seldom reported earlier. This knowledge about the variations in the lateral wall of the nasal cavity is crucial during the endoscopic interventions and for functional endoscopic sinus surgeries.

    Maxillary sinus lifting is a technique, in which, a possible complication is sinus membrane perforation. The aim of this study was to compare two techniques using ultrasound surgery to perform autogenous graft for maxillary sinus lifting. Ten rabbits were used in the study, one of them did not undergo surgery. The other nine rabbits had their maxillary sinuses filled with autogenous bone grafts collected from the external skull diploe in particulate form on the right side, and shaved on the left side, both with ultrasonic device. Data on bone density in left and right maxillary sinus, obtained by computed tomography in transverse and longitudinal sections, recorded 90 days after the grafts, were statistically compared. There were no statistically significant differences between the two techniques that used shaved and particulate bone collected by means of ultrasonic device from rabbit skulls. Assessment of operative procedures led to the conclusion that piezoelectric ultrasound was shown to be a safe tool in the surgical approach to the maxillary sinus of rabbits, allowing sinus membrane integrity to be maintained during surgical procedures.

    Full Text Available This study aims to determine the relationship between nasal septal deviation, concha bullosa, and chronic rhinosinusitis by using a definitive pathological and simplified model. Fifty-two consecutive sinus computed tomography scans were performed on patients who received endoscopic sinus surgery and whose final diagnosis was paranasal sinus fungus balls. The incidences of nasal septal deviation and concha bullosa for patients diagnosed with paranasal sinus fungus balls among the study group were 42.3% and 25%, respectively. About 63.6% sinuses with fungus balls were located on the ipsilateral side of the nasal septal deviation, and 46.2% were located on the ipsilateral side of the concha bullosa. When examined by Pearson’s chi-square test and the chi-squared goodness-of-fit test, no significant statistical difference for the presence of paranasal sinus fungus balls between ipsilateral and contralateral sides of nasal septal deviation and concha bullosa was noted (P=0.292 and P=0.593, resp.. In conclusion, we could not demonstrate any statistically significant correlation between the location of infected paranasal sinus, the direction of nasal septal deviation, and the location of concha bullosa, in location-limited rhinosinusitis lesions such as paranasal sinus fungal balls. We conclude that the anatomical variants discussed herein do not predispose patients to rhinosinusitis.

    Full Text Available Foreign bodies in maxillary sinuses are unusual clinical conditions, and they can cause chronic sinusitis by mucosal irritation. Most cases of foreign bodies in maxillary sinus are related to iatrogenic dental manipulation and only a few cases with non-dental origin are reported. Oroantral fistulas secondary to dental procedures are the most common way of insertion. Treatment is surgical removal of the foreign body either endoscopically or with a combined approach, with Caldwell-Luc procedure if endoscopic approach is inadequate for visualisation. In this case, we present a 24-year-old male patient with unilateral chronic maxillary sinusitis due to a wooden toothpick in left maxillary sinus. The patient had a history of upper second premolar tooth extraction. CT scan revealed sinus opacification with presence of a foreign body in left maxillary sinus extending from the floor of the sinus to the orbital base. The foreign body, a wooden toothpick, was removed with Caldwell-Luc procedure since it was impossible to remove the toothpick endoscopically. There was no obvious oroantral fistula in the time of surgery, but the position of the toothpick made us to think that it was inserted through a previously healed fistula, willingly or accidentally.

    2010-06-01

    Full Text Available Modern techniques of radiological examination form the basis for additional diagnostic and planning methods of surgical treatment in oral surgery and implantology. Assessment of maxillary sinus condition and sinuslifting results is a part of preoperative examination before dental implantation. The estimated results of digital volume tomography after sinuslifting have shown that 51,1% of patients have lack of volume of implant on the medial wall of the sinus. That does not allow placing dental implant in correct position. The digital volume tomography is highly informative and convenient radiological examination method in diagnosis of maxillary sinus condition, assessment of sinuslifting results and application of further dental implantation

    Isolated sphenoid sinus pathology is a relatively uncommon entity. The present study is a retrospective review of 40 patients with isolated sphenoid sinus pathology who were treated at the Department of Otorhinolaryngology, Alexandria University between July 2002 and December 2005. Special emphasis will be given to the role of various endoscopic approaches in the surgical management of isolated sphenoid sinus pathology. Factors that govern the selection of each approach will be discussed. Extracted data included patient demographics, clinical presentation, imaging studies, treatment modalities and complications. Sphenoid sinus was approached through one of the following three approaches: (1) endoscopic transnasal approach, (2) endoscopic transseptal approach and (3) endoscopic transpterygoid approach. Outcome measures were based on assessment of patients' symptoms and confirmation of a patent sphenoid sinus by office endoscopy. The pathology spectrum was rather wide and included 26 (65%) inflammatory conditions (acute/chronic sphenoiditis, mucoceles, and fungal sinusitis), 7 (17.5%) neoplasms and 7 (17.5%) miscellaneous conditions (cerebrospinal fluid (CSF) rhinorrhea, sphenochoanal polyp, and fibrous dysplasia). The most common initial symptom was headache (50%) followed by ophthalmological symptoms (22.5%). Other presenting symptoms included CSF leak in five patients, epistaxis in four patients and nasal obstruction and/or rhinorrhea in two patients. Radiological workup included computed tomography (CT) scan of the paranasal sinuses in all patients. Magnetic resonance imaging (MRI) was performed in 21 patients (52.5%). The most common indication was a sphenoid mass based on endoscopic and CT findings. Four patients with acute/chronic sphenoiditis were successfully treated with medical therapy. One patient with fibrous dysplasia did not require any definitive treatment. Thirty-five patients underwent endoscopic surgery under general anaesthesia. An adjuvant

    Full Text Available Oral rehabilitation with dental implants has become a routine treatment in contemporary dentistry. The displacement of dental implants into the sinus membrane, a complication related to the maxillary sinus, is one of the most common accidents reported in the literature. The treatment for this complication is the surgical removal of the implant. A 60-year-old woman with three dental implants displaced into the maxillary sinus (one implant displaced into the left maxillary sinus and two implants displaced into the right maxillary sinus underwent surgery for removal of the implants. The surgery to remove the implants was performed under local anesthesia through the Caldwell-Luc technique. The patient was subsequently administered antibiotic, anti-inflammatory, and analgesic drugs. The patient returned 7 days after the surgery for suture removal and is being regularly monitored to determine whether future rehabilitation of the edentulous area is necessary. In conclusion, surgical removal of the dental implant displaced into the maxillary sinus is the treatment of choice. This technique is appropriate because it allows the use of local anesthesia and provides direct visualization for the removal of the implants.

    Allergic fungal sinusitis (AFS) is a condition that has an allergic basis caused by exposure to fungi in the sinonasal tract leading to chronic inflammation. Despite standard treatment modalities, which typically include surgery and medical management of allergies, patients still have a high rate of recurrence. Subcutaneous immunotherapy (SCIT) has been used as adjuvant treatment for AFS. Evidence exists to support the use of sublingual immunotherapy (SLIT) as a safe and efficacious method of treating allergies, but no studies have assessed the utility of SLIT in the management of allergic fungal sinusitis. A record review of cases of AFS that are currently or previously treated with sublingual immunotherapy from 2007 to 2011 was performed. Parameters of interest included serum IgE levels, changes in symptoms, Lund-McKay scores, decreased sensitization to fungal allergens associated with AFS, and serum IgE levels. Ten patients with diagnosed AFS were treated with SLIT. No adverse effects related to the use of SLIT therapy were identified. Decreases in subjective complaints, exam findings, Lund-McKay scores, and serum IgE levels were observed. Thus, sublingual immunotherapy appears to be a safe adjunct to the management of AFS that may improve patient outcomes. © The Author(s) 2015.

    Full Text Available Cerebral sinus venous thrombosis (CSVT is a rare phenomenon that can be seen with some frequency in young patients. CSVT is a multifactorial condition with gender-related specific causes, with a wide clinical presentation, the leading causes differ between developed and developing countries, converting CSVT in a condition characterized by a highly variable clinical spectra, difficult diagnosis, variable etiologies and prognosis that requires fine medical skills and a high suspicious index. Patients who presents with CSVT should underwent to CT-scan venography (CVT and to the proper inquiry of the generating cause. This disease can affect the cerebral venous drainage and related anatomical structure. The symptoms may appear in relation to increased intracranial pressure imitating a pseudotumorcerebri. Prognosis depends on the early detection. Correcting the cause, generally the complications can be prevented. Mortality trends have diminished, and with the new technologies, surely it will continue. This work aims to review current knowledge about CSVT including its pathogenesis, etiology, clinical manifestations, diagnosis, and treatment.

    Full Text Available Background: Sinuslift is meanwhile an established method of bone augmentation in the posterior maxilla. Aim of the study was to evaluate the significance of intraoperative Schneiderian membrane perforations during maxillary sinus floor elevation surgery using autogenous bone harvested from two different donor sites using a Safescraper device on the success rate, graft survival and implant integration.Methods: The investigators conducted a retrospective cohort study at the Department of Oral and Maxillofacial Surgery of Military Hospital Ulm composed of patients with severe maxillary atrophy who underwent sinus augmentation from January 2011 until December 2011. Ninety-nine consecutive patients (89 men, 10 women with a mean age of 43.1 years underwent sinus graft procedures in a 2-stage procedure using the lateral wall approach, as described by Tatum (1986. Data on patient age, smoking status, donor site and surgical complications were recorded and the relationship between Schneiderian membrane perforation and complication rate was evaluated. Dental implants were inserted 4 months after grafting.Results: A total of 105 sinus lift procedures were performed in 99 patients. Sixty-one patients (61.6% underwent sinus elevation with autogenous bone from the buccal sinus wall, while 38 patients (38.4% bone harvesting from the iliac crest. Intraoperative perforation of the Schneiderian membrane was observed in 11 of the 105 sinuses (10.4%. These perforations resulted in 4 (36.3% of the cases in major postoperative complications accompanied by swelling and wound infection. Membrane perforations were slightly associated with the appearance of postoperative complications (p=0.0762. In 2.4% of all cases, regarding 2 patients the final rehabilitation with dental implants was not possible because of extensive bone resorption. Conclusion: Intraoperative complications performing sinus augmentation may lead to postoperative complications. With careful clinical

    Forty patients with squamous cell carcinoma in the maxillary sinus were investigated between 1989 and 1999. They consisted of 28 males and 12 females. Their ages ranged from 18 to 84 years (mean 62 years). According to the 1987 UICC TNM classification system, 3 patients were classified as stage II, 3 were stage III and 34 were stage IV. The overall three-year and five-year survival rates were 52% and 44%, respectively. Local recurrence was observed in 11 stage IV cases and 10 of them were not controlled. For further improving the prognosis of such patients, new techniques such as skull base surgery, super selective intraarterial chemotherapy, and concurrent chemo-radiation should be included in the treatment regimen.

    Pilonidal sinus disease is thought to be caused by intrusion of hair into healthy skin; loose hair in the intergluteal fold is thought to promote disease. However, compelling evidence to support these postulates is lacking; the cause of pilonidal sinus disease remains uncertain. To determine whether particular properties of hair are associated with susceptibility to pilonidal sinus disease, we compared physical properties of hairs of patients with pilonidal sinus disease with hairs from control subjects who were matched for sex, BMI, and age. This was an experimental study with establishment of a mechanical strength test for single hairs to quantify the maximum vertical force that a hair could exert, following tests of strength of occipital, lumbar, and intergluteal hair. Hair from patients with pilonidal sinus disease and matched control subjects were harvested from patients of the St. Marienhospital Vechta Department of Procto-Surgery. A total of 17 adult patients with pilonidal sinus disease and 217 control subjects were included. ANOVA and intraclass and interclass variations of data gained from mechanical strength tests of occipital, lumbar, and intergluteal hair were included. Vertical hair strength was significantly greater in patients with pilonidal sinus disease. Occipital hair exhibited 20% greater, glabella sacralis 1.1 times greater, and intergluteal hair 2 times greater strength in patients with pilonidal sinus disease than in matched control subjects (all p = 0.0001). In addition, patients with pilonidal sinus disease presented with significantly more hair at the glabella sacralis and in the intergluteal fold. The study was limited by its relatively small number of patients from a specific cohort of European patients. Occipital hair exhibited considerable vertical strength. Because occipital hair exerted the greatest force and cut hair fragments were found in the pilonidal nest in large quantities, these data suggest that pilonidal sinus disease is

    The purpose of this work was to evaluate the feasibility of tagging (highlighting) surgical sites using volumetric CT virtual reality of the paranasal sinuses in the planning for endoscopic sinus surgery. Twenty-five patients with significant paranasal sinus disease had a planned surgical site marked on 2D coronal images. This planned surgical site was then tagged and included on CT volumetric virtual reality imaging. Each case was evaluated as to the ability of the CT virtual reality to demonstrate the planned surgical site and its orientation with respect to adjacent superficial anatomy. For all 25 planned surgeries, the virtual images showed the entire surgical site marked on the 2D coronal images. In all 25 cases, the orientation of the planned surgical site to adjacent normal anatomy was well demonstrated. For surgery into the maxillary sinuses, tagging and electronic removal of the middle turbinates and uncinate processes mimicked the actual surgery and allowed complete visualization of the infundibulum and the planned surgical site. Planned endoscopic paranasal sinus surgical sites can be easily and reliably highlighted using CT virtual reality techniques with respect to the patient's normal endoscopic anatomy.

    The authors present a case of congenital dermal sinus tract with epidermoid tumor. This 1-year-old boy was referred to the pediatric service of another hospital with recurrent pyrexia of unknown origin in April, 1999. The pediatrician found two dimples, pigmentation, and coarse hairs on the midline in his sacral region. Computerized tomography (CT) scans revealed a spina bifida below the S1 level. Magnetic resonance (MR) imaging revealed a dermal sinus tract in the cranial direction to a cystic tumor at L2-4 levels. He was transferred to our hospital, and the tract and tumor were totally removed in June, 1999. The histological findings and Escherichia coli in the smear culture of the tumor contents identified it as an infected congenital dermal sinus tract with epidermoid tumor. The patient received antibiotics for two weeks after surgery and there was no clinical or radiographic recurrence of either infection or tumor. The authors propose early diagnosis and radical treatment, because infected congenital dermal sinus tract often leads to a bad neurological prognosis.

    An osteoblastoma is a benign bone tumor that most often occurs in the vertebral column and the long bones of the extremities. Paranasal sinus involvement is very rare. We report an osteoblastoma of the ethmoid sinus in a 13-year-old boy who presented with exophthalmos. CT demonstrated an expansile, lesion of the right ethmoid sinus, which caused the orbital contents to be compressed and deviated to the right. A mixture of ground glass opacity and dense bone was present. The less dense portions of the lesion showed intense enhancement on MRI; a signal void was present on all sequences in the densely sclerotic areas. Curettage was performed. Histologically, the lesion was composed of proliferating osteoblasts along with small trabeculae of woven bone and rich vascular fibrous stroma. The literature concerning occurrence of osteoblastoma in this unusual location is reviewed and discussed. (orig.)

    Fibrous dysplasia (FD) of the paranasal sinuses is rare and often presents a diagnostic challenge. It is usually secondary to extension of disease from adjacent bones and is rarely limited to the sinuses. We have described three cases of FD involving the paranasal sinuses, including the first reported case of FD isolated to the sphenoid sinus. A brief update of the clinical aspects, radiographic appearance, diagnosis, and management of craniofacial FD is provided.

    Although a variety of theories have been proposed about functions of the paranasal sinuses, not one is clear today. Nonetheless, paranasal sinus?related diseases are associated with a high rate of morbidities. Therefore, it is essential to identify the structure and pathophysiology of the paranasal sinuses. Computed tomography (CT) is a valuable tool displaying anatomic variations and diseases. Because paranasal sinus development is a complex and long-lasting process, there are great structur...

    Full Text Available Objective To investigate clinicopathological features, immune phenotype, diagnosis and differential diagnosis of alveolar soft-part sarcoma (ASPS in paranasal sinuses. Methods Retrospective study of clinical manifestations, histopathological features and immunohistochemical features was conducted in one case of ASPS in paranasal sinuses.  Results A 28-year-old female presented with bulging forehead for 2 months. MRI revealed a well-circumscribed lesion in left frontal and ethmoid sinuses extending to anterior skull base that showed slightly hyperintense signal on T1WI and hypointense signal on T2WI without obvious enhancement after contrast administration. The patient subsequently underwent endoscopic open surgery on left ethmoid and bilateral frontal sinuses and performed partial resection of the lesion. Three months after the initial surgery, the patient received reoperation for total removal of residual lesion and reconstructive surgery of anterior skull base. Adjuvant chemotherapy and radiotherapy were not administered. Histologically, the tumor was composed of epithelioid cells arranged in organoid nests and/or alveolar structures varying in size and shape, which were separated by connective tissue richly containing sinusoidal vascular channels. The tumor cells were generally large-sized, round, oval or polygonal with abundant eosinophilic granular or translucent vacuolated cytoplasm. The nuclei showed round or oval shape containing centrally placed and obvious nucleoli. The presence a lot of mono- or multi-nuclear giant cells served as another striking feature. Mitotic activities were rare. Reticular fiber staining indicated that reticular fibers surrounded the nest of tumor cells, and diastase-resistant periodic acid-Schiff (PAS-positive crystalline inclusions were identified within the cytoplasm of tumor cells. Immunohistochemically, the tumor cells were reactive for TFE3, while were negative for glial fibrillary acidic protein (GFAP

    To study potential benefits of postoperative epilation after pilonidal sinus surgery, the long-term effect of hair removal on pilonidal recurrence was investigated. A total of 1,960 patients with pilonidal sinus treated surgically from 1980 to 1996 in three hospitals of the Deutsche Bundeswehr were eligible for the study. Regular hair removal with a razor was recommended for all patients after surgery. A randomly selected sample of 504 patients was contacted for a follow-up telephone interview. The mean follow-up time was 11.3 (standard deviation, 6.4) years. Overall, pilonidal sinus disease recurred in 111 (22 percent) of the 504 patients. A total of 113 patients followed the recommendation to perform epilation (mean duration, 7.5 months), and 391 patients did not. Recurrence was observed in 30.1 percent (34/113) of patients who performed postoperative epilation and in 19.7 percent (77/391) of patients who did not perform postoperative epilation (P = 0.01). Razor hair removal increases the rate of long-term recurrence after surgery for pilonidal sinus disease and therefore should not be recommended. However, the rationale for hair removal in pilonidal sinus disease is compelling. Other epilation techniques such as laser hair removal should be investigated in appropriate studies.

    We report the case of a 25-year-old patient, diagnosed at age 10, with diffuse fibrous dysplasia of the paranasal sinuses, an extremely rare idiopathic condition. This diagnosis is possible only by cerebral computed tomography (CT), cerebral and anterior skull base magnetic resonance imaging (MRI), and histopathology. Surgical treatment is common. This boy had mild symptoms: moderate headache in the morning that did not affect his daily activity, and rhinitis, partially responsive to medication. The neurologic examination was abnormal. Radiographs, CT, and MRI showed a diffuse mass in the paranasal sinuses which had a histopathological diagnosis of fibrous dysplasias. The family refused to refer the patient to surgery. The boy has been monitored annually for 15 years. He has remained asymptomatic without headache since age 11, with normal, general and neurologic examinations. Serial MRIs showed a spontaneous partial involution of the mass. © The Author(s) 2014.

    To assess natural history, treatment outcome and pattern of relapse in patients with maxillary sinus carcinoma. A review was conducted of the medical records of all adult patients with maxillary sinus carcinoma, who were treated at King Faisal Hospital and Research Centre, Riyadh, Kingdom of Saudi Arabia, between January 1990 and December 1999. A total of 60 patients were identified for analysis, 36 men and 24 women; the median age was 58-years (range 23-95). Major presenting symptoms were facial swelling 55%, facial pain 50%, and nasal obstruction 43.4%, with a median duration of 5-months (range 1-24). Histology was quamous cell carcinoma in 71.7% and adenoid cystic in 16.7%. They were restaged according to American Joint Committee on Cancer classification 1997 as II, III and IV in 1, 10 and 49. Thirty patients received treatment with curative intent (surgery in 4 patients, radiotherapy in 2, and combined modality in 24), 6 patients refused treatment and 24 were treated palliatively. With a median follow up of 50-months (range 2-128) in surviving patients treated with a curative intent, 12/30 failed locally, 4/30 in the regional neck nodes and 2/30 had systemic relapse. The actuarial 5-year overall survival (OS), relapse free survival (RFS) and local control rate (LC) were 55%, 39% and 51%. Treatment modality was the only significant prognostic factor for outcome, with 5 year OS, RFS and LC of 72%, 49% and 61%, for combined modality using surgery followed by radiotherapy compared to 0% for single approach (p=0.0003, p=0.0052 and p=0.0098). This study indicates that the majority of our patients presented with advanced disease, resulting in poor outcome to conventional treatment modalities. Efforts should be directed to minimize the delay in diagnosis at the primary care level. Combined modality treatment should be offered to all patients with locally advanced disease. New approaches such as neoadjuvant or concurrent chemoradiotherapy with or without surgery need to

    The objective of this study was to comparatively evaluate 3 different sinus lift tools, namely umbrella-shaped sinus lift curette YSL-04, our recently designed probe-improved sinus lift curettes, and our newly invented elevator 014, using our previous developed goat ex vivo models for direct visualizing the effectiveness of detaching sinus mucosa in real time. Goat ex vivo models for direct visualizing the effectiveness of detaching sinus mucosa in real time were generated according to our previously developed protocol. The effectiveness for each tool was evaluated through the length of sinus mucosa detached in mesial and distal directions or buccal and palatal directions, and the space volume created by detaching maxillary sinus mucosa in mesial, distal, buccal and palatal directions. The results showed that all 3 sinus lift tools could transcrestally detach the maxillary sinus mucosa and create extra space under the elevated sinus floor on the goat ex vivo sinus models. Moreover, our newly invented elevator 014 had advantages over the other 2 in term of the capability to detach the sinus mucosa. Our newly invented elevator 014 might be a promising tool for detaching maxillary sinus mucosa in transcrestal maxillary sinus floor elevation.

    Mucoceles are cystic masses that generally affect the sinuses. It occurs as a result from obstruction of the ostium of a sinus and consequential accumulation of mucus. Frontal and ethmoid sinuses are mostly affected. Usually, the clinical symptoms are insidious, varying with the extent of the affected region. The treatment is surgical and endoscopic surgery is the method of choice in most cases. The present study is aimed at describing the main characteristics of paranasal sinuses mucoceles, demonstrating and illustrating a series of atypical presentations with emphasis on imaging findings.

    The purpose of this study was to evaluate the computed tomographic (CT) images of the paranasal sinusitis(PNS). The author examined the extent and the recurring patterns of the paranasal sinusitis and some important anatomic landmarks. The author analyzed PNS images retrospectively in 500 patients who visited Chonbuk National University Hospital between January 1996 and December 1997. The most frequently affected sinus was maxillary sinus (82.9%), followed by anterior ethmoid sinus (67.9%), posterior ethmoid sinus (48.9%), frontal sinus (42.0%) and sphenoid sinus (41.4%). The characteristic features of CT images of the sinusitis were sinus opacification (22.4%), mucoperiosteal thickening (34.3%), and polyposis (2.0%). Sinonasal inflammatory diseases were categorized into 5 patterns according to Babbel's classification. They were 1) infundibular (13.0%), 2) ostiomeatal unit (67.4%), 3)sphenoethmoidal recess (13.0%), 4) sinonasal polyposis (9.6%) and 5) unclassifiable patterns (18.0%). The incidences of contact between sinus and optic nerve were as follows ; the incidences of contact with posterior ethmoid sinus, sphenoid sinus, both posterior sinuses were 11.4%, 66.8%, 6.3%, respectively. The incidences of contact between sphenoid sinus and maxillary nerve, vidian nerve, internal carotid artery were 74.5%, 79.2%, 45.1% respectively. The incidences of pneumatization of the posterior ethmoid sinus were as follows; normal 70.6% and overriding type 29.4%. The incidences of sphenoid sinus pneumatization were as follows; normal 56.9% , rudimentary 12.5%, pterygoid recess 22.7%, anterior clinoid recess 2.7%, and both pterygoid and anterior clinoid recess 5.2%. The inflammatory sinonasal diseases were classified into five patterns using the CT of PNS, which was proven to be an excellent imaging modality providing detailed information about mucosal abnormality, pathologic patterns and the proximity of the important structures to the posterior paranasal sinuses.

    We describe a rare case of a sphenoid sinus myxoma that was resected via an endoscopic endonasal skull base approach. We review the literature regarding these rare tumors of the paranasal sinuses. A 72-year-old woman was diagnosed with an incidental sphenoid sinus tumor and left sphenoid wing meningioma during a workup for left-sided proptosis and diplopia. Biopsies of the sphenoid wing and sphenoid sinus tumors were obtained. After undergoing surgical resection of the meningioma, the patient then underwent definitive resection of the sphenoid sinus myxoma via endoscopic endonasal skull base approach. Postoperative imaging demonstrated a gross total resection. The patient suffered postoperative thromboembolic complications due to underlying hypercoagulable state but made a complete recovery and returned to her neurologic baseline. There has been no evidence of recurrent myxoma in the sphenoid sinus 24 months after surgery. Myxomas are benign tumors derived from primitive mesenchyme. Myxomas very rarely present in the paranasal or skull base location. Complete surgical resection is the primary treatment for these tumors. The endoscopic endonasal approach is an effective technique for resecting various benign and more aggressive extradural skull base tumors. Myxomas of the sphenoid sinus are rare. The endoscopic endonasal skull base approach is an effective and minimal access technique for resection of this rare tumor of the sphenoid sinus. Copyright © 2017 Elsevier Inc. All rights reserved.

    Osteoblastoma is a rare benign bone tumor that occurs unusually in the nasal sinuses. We report one case of sinonasal osteoblastoma in a 12-year-old girl who presented with nasal obstruction and telecanthus on the right side. Computed tomography revealed a lesion of the right ethmoid sinus with heterogenous bony density, which was displacing the orbital contents and the skull base. Biopsy caused significant bleeding. Magnetic resonance imaging showed intense homogeneous enhancement with typical flow-void areas due to large pathological vessels. This MRI feature must alert the clinician on the diagnosis before biopsy and surgical resection after embolization is performed. This case report describes the diagnostic and therapeutic difficulties of this rare tumor.

    Otolaryngologists, dentists and maxilla-facial surgeons see patients suffering from odontogenic maxillary sinusitis on a daily routine. The study was performed to investigate the different origins of the odontogenic maxillary sinusitis ranging from periodontitis to augmentative implant surgery. Furthermore, the microbial flora of purulent odontogenic maxillary sinusitis was analyzed in order to present a proper antibiotic treatment in addition to a surgical approach. A retrospective study was performed, analyzing the clinical trials of 121 patients suffering from odontogenic maxillary sinusitis who undergone surgery. Harvested bacteria were tested for susceptibility on a routine base, surgical reports of removed foreign material or dental focus were reviewed as well as preoperative CBCT. Patients mean age was 56.62 (±16 SD) with a slight female gender dominance. Allergic profile to β-lactam antibiotics had no influence on patients' length of in-hospital stay. 69 out of 121 cases of OMS occurred after dental surgery (extractions, augmentation or implant surgery). Maxillary molars were the teeth mostly hold accountable for an onset without surgery in recent history. 22.3% of the patients possessed a dislocated foreign body in the maxillary sinus. Pseudomonas aeruginosa infection was significantly associated with misplaced foreign bodies (root filling, augmentative dental material e.g. p < 0.05). We protocoled an anaerobic dominance with 45 anaerobes versus 19 aerobes. Ampicillin/Sulbactam (80%) and Piperacillin/Tazobactam (93.3%) present sufficient susceptibly rates to the harvested bacteria. Likewise showed Moxifloxacin (86.3%) equal results, whereas Clindamycin had a poor outcome with merely 50% of the tested bacteria being susceptible to Clindamycin. If OMS is diagnosed dental focus should be treated, misplaced bodies should be removed and purulent exacerbation has to be additionally treated with a calculated antibiotic therapy according to the pathogens

    2009-12-01

    Frontal sinus fractures (FSF) are commonly caused by traffic accidents, assaults, industrial accidents and gunshot wounds. Classical roentgenography has high proportion of false negative findings in cases of FSF and is not particularly useful in examining the severity of damage to the frontal sinus posterior table and the nasofrontal duct region. High resolution computed tomography was inavoidable during the management of such patients but it may produce large quantity of 2D images. Postprocessing of datasets acquired by high resolution computer tomography from patients with severe head trauma may offer a valuable additional help in diagnostics and surgery planning. We performed virtual endoscopy (VE) and 3D volume rendering (3DVR) on high resolution CT data acquired from a 54-year-old man with with both anterior and posterior frontal sinus wall fracture in order to demonstrate advantages and disadvantages of these methods. Data acquisition was done by Siemens Somatom Emotion scanner and postprocessing was performed with Syngo 2006G software. VE and 3DVR were performed in a man who suffered blunt trauma to his forehead and nose in an traffic accident. Left frontal sinus anterior wall fracture without dislocation and fracture of tabula interna with dislocation were found. 3D position and orientation of fracture lines were shown in by 3D rendering software. We concluded that VE and 3DVR can clearly display the anatomic structure of the paranasal sinuses and nasopharyngeal cavity, revealing damage to the sinus wall caused by a fracture and its relationship to surrounding anatomical structures.

    To evaluate the anatomic variations of the paranasal sinuses on computed tomographs. The author examined the CT images of the paranasal sinuses retrospectively in 500 patients who visited Chonbuk National University Hospital between January 1996 and December 1997. The highest incidence of anatomic variation of the paranasal sinuses in bilateral structures was agger nasi cell (73.2%), followed by concha bullosa (31.1%), Onodi cell (24.0%), Haller cell (19.8%), maxillary sinus septum (13.0%), paradoxical middle turbinate (2.5%), pneumatized uncinate process (2.0%), and bent uncinate process. The highest incidence of anatomic variation in midline structures was nasal septum deviation(53.2%), followed by nasal septumaerated (29.4%), bulla galli (24.7%) asymmetric intersphenoid septum (22.3%), and nasal septum spur (13.8%). The correlation between anatomic variation and paranasal sinusitis was not found. The results of this study will aid in the diagnosis and treatment of paranasal sinus diseases, especially in the treatment planning before functional endoscopic surgery.

    Full Text Available Mohammed Jasim Al-Juboori Department of Oral Surgery, MAHSA University, Kuala Lumpur, Malaysia Abstract: The displacement of a dental implant into the maxillary sinus may lead to implant failure due to exposure of the apical third or the tip of the implant beyond the bone, resulting in soft tissue growth. This case report discusses dental implant placement in the upper first molar area with maxillary sinus involvement of approximately 2 mm. A new technique for progressive implant loading was used, involving immediately loaded implants with maxillary sinus perforation and low primary stability. Follow-up was performed with resonance frequency analysis and compared with an implant placed adjacent in the upper second premolar area using a conventional delayed loading protocol. Implants with maxillary sinus involvement showed increasing stability during the healing period. We found that progressive implant loading may be a safe technique for the placement of immediately loaded implants with maxillary sinus involvement. Keywords: progressive implant loading, resonance frequency analysis, implant stability, provisional crown, bone density, maxillary sinus

    Sinus fungus ball, an accumulation of fungal dense concretions, is a common disease in practice, and might cause fatal complications or lead to death once converted into invasive type. Early preoperative diagnosis of this disease can lead to appropriate treatment for patients and prevent multiple surgical procedures. Up to now, the diagnostic criteria of sinus fungus ball have been defined and computed tomography (CT) scan was considered as a valuable preoperative diagnostic tool. However, the sensitivity of clinical CT is only about 62%. Thus, investigating the factors which influence sensitivity is necessary for clinical CT to be a more valuable preoperative diagnosis tool. Furthermore, CT scan usually presents micro-calcifications or spots with metallic density in sinus fungus ball. Previous literatures show that there are some metallic elements such as calcium and zinc in fungus ball, and they concluded that endodontic treatment has a strong correlation with the development of maxillary sinus fungus ball and zinc ion was an exogenous risk factor. But the pathogenesis of sinus fungus ball still remains unclear because fungus ball can also develop in other non-maxillary sinuses or the maxillary sinus without root canal treatment. Is zinc ion the endogenous factor? Study on this point might be also helpful for investigating the pathogenesis of sinus fungus ball. In this paper, we tried to investigate the factors which influence the sensitivity of clinical CT by imaging sinus fungus ball with microCT. The origin of zinc ion was also studied through elements test for different fungal ball samples using x-ray fluorescence technique. Specimens including fungal ball material and sinus mucosa from patients confirmed by pathological findings were extracted after surgery. All fungal ball specimens came from sphenoid sinus, ethmoidal sinus and maxillary sinus with or without previous endodontic treatment respectively. All of them were imaged by microCT with spatial

    To evaluate the anatomical relation between anterior ethmoidal sinus and the lacrimal sac fossa, and thus help prevent complications during dacryocystorhinostomy. Fifty three people without previous history of trauma, surgery, or paranasal sinus disease were randomly selected, and the 106 lacrimal sac fossas of these subjects were evaluated by high resolution CT. A series of three 2-mm thick axial sections at least 2mm from the inferior orbital wall were obtained. The bony landmarks of the lacrimal sac fossa were established and the location of the most anterior ethmoid sinus was classified as one of three types. In type 1, no sinuses were anterior to the posterior lacrimal crest. While in type 2, sinuses extended anterior to this crest but remained behind the suture at the anterior edge of the lacrimal bone. In type 3, sinuses extended into the frontal process of the maxilla, anterior to the lacrimal bone suture. In addition, the category of both orbits of the same patient was compared. Among the 106 orbits examined, only seven (6.6%) were classified as type 1, with no ethmoid air cells postioned under the lacrimal sac fossa. Seventy six (71.7%) qualified as type 2, while the remaining 23 (21.7%) were type 3, demonstration anterior ethmoid air cells within the nasal process of the maxilla. The position of the air cells was symmetric in 41 of the 53 subjects (77.4%) and asymmetric in 12 (22.6%). In cases involving surgery of the lacrimal sac fossa, such as dacryocystorhinostomy, a knowledge of the consistent anatomic relationship between the anterior ethmoidal sinus and the lacrimal sac fossa is invaluable

    Background: Although the imaging features of sigmoid sinus diverticulum induced pulsatile tinnitus (PT) have been presented in some extent, detailed imaging findings still have not been systematically evaluated and precise diagnostic radiographic criteria has not been established. Purpose: To examine the computed tomography (CT) characteristics of sigmoid sinus diverticulum accompanied with PT. Material and Methods: Fifteen PT patients with sigmoid sinus diverticula proven by surgery were recruited after consenting. CT images of 15 patients were obtained and analyzed, including features of diverticula, brain venous systems, integrity of the sigmoid plate, and the degree of temporal bone pneumatization. Results: Sigmoid sinus diverticulum was located on the same side of PT in 15 patients. Diverticula originated at the superior curve of the sigmoid sinus in 11 patients and the descending segment of the sigmoid sinus in four patients. Sigmoid sinus diverticula focally eroded into the adjacent mastoid air cells in 12 patients and mastoid cortex in three patients. Among eight patients with unilateral dominant brain venous systems, the diverticula were seen on the dominant side in seven patients and non-dominant side in one patient. In contrast, the other seven patients showed co-dominant brain venous systems, with three presenting diverticula on the right side and four on the left. More notably, dehiscent sigmoid plate on the PT side was demonstrated in all patients. In addition, temporal bone hyper-pneumatization was found in nine patients, good and moderate pneumatization in three patients, respectively. Conclusion: Dehiscent sigmoid plate and extensive temporal bone pneumatization are two important imaging characteristics of the PT induced by sigmoid sinus diverticulum.

    Full Text Available Background: Fungal sinusitis is increasing worldwide in the past two decades. It is divided into two types including invasive and noninvasive. Noninvasive types contain allergic fungal sinusitis (AFS and fungus ball. AFS is a hypersensitivity reaction to fungal allergens in the mucosa of the sinonasal tract in atopic individuals. The fungus ball is a different type of noninvasive fungal rhinosinusitis which is delineated as an accumulation of debris and fungal elements inside a paranasal sinus. Fungal sinusitis caused by various fungi such as Aspergillus species, Penicillium, Mucor, Rhizopus, and phaeohyphomycetes. The aim of the present study is to identify fungal species isolated from noninvasive fungal sinusitis by molecular methods. Materials and Methods: During 2015–2016, a total of 100 suspected patients were examined for fungal sinusitis. Functional endoscopic sinus surgery was performed using the Messerklinger technique. Clinical samples were identified by phenotypic and molecular methods. Polymerase chain reaction (PCR sequencing of ITS1-5.8S-ITS2 region and PCR-restriction fragment length polymorphism with Msp I restriction enzyme was performed for molecular identification of molds and yeasts, respectively. Results: Twenty-seven out of 100 suspected cases (27% had fungal sinusitis. Nasal congestion (59% and headache (19% were the most common clinical signs among patients. Fifteen patients (55.5% were male and 12 patients (44.5% were female. Aspergillus flavus was the most prevalent fungal species (26%, followed by Penicillium chrysogenum (18.5% and Candida glabrata species complex (15%. Conclusion: Since clinical manifestations, computed tomography scan, endoscopy, and histopathological findings are very nonspecific in AFS and fungus ball; therefore, molecular investigations are compulsory for precise identification of etiologic agents and appropriate management of these fungal infections.

    Full Text Available Introduction: Umbilical disorders are frequently encountered in general surgical practice. Although the sacrococcygeal region is the most common site for pilonidal sinus disease, it can be seen occasionally in periumbilical area. Treatment is mostly conservative for umbilical pilonidal sinus in contrast to the sacrococcygeal sinus where it is always surgical. In the era of endoscopy and minimally invasive surgery, we describe the use of otoscope as a novel technique for the diagnosis and treatment of umbilical pilonidal sinus. Subject and Method: In this prospective study, patients with a clinical suspicion of umbilical pilonidal sinus were included and diagnosis was confirmed on the basis of otoscopic finding. All patients were planned for conservative management i.e. extraction of hair fragments with the help of an otoscope followed by oral antibiotics treatment. On follow-up, response of treatment was noted by evaluation of symptoms and otoscopic examination.Result: Total 15 patients were included in this study. By using otoscope for removal of hair fragments from umbilical sinus, we found successful result in all patients with conservative treatment. Discussion: In umbilical pilonidal sinus, the success of conservative treatment depends on the effective extraction of hair and maintenance of personal hygiene by the patient. Our study showed 100% successful result of conservative treatment, probably due to proper and complete extraction of hair fragment with the help of the otoscope. Conclusion: Otoscopic examination and hair extraction for umbilical pilonidal sinus is a simple, cost-effective, and easy treatment that can be done in the outpatient department and does not require any formal training for its use.

    To report a case of Pythium insidiosum keratitis leading to fatal cavernous sinus thrombophlebitis. Case report. A 70-year-old man presented with excruciating pain, redness, and diminution of vision in his left eye for 2 weeks after washing his hair with tap water. A total corneal ulcer with surrounding infiltrates and associated corneal thinning was present. Corneal scraping revealed the presence of Gram-positive cocci. KOH wet mount and in vivo confocal microscopy revealed branching hyphae. Combined antibacterial and antifungal treatment was started, but 4 days later, the ulcer showed signs of worsening with perforation for which a large therapeutic penetrating keratoplasty was done. The host cornea showed branching septate hyphae on Sabarouds Dextrose Agar. Two weeks later, the patient developed left eye proptosis with associated extraocular movement restriction. Magnetic resonance imaging of the head and orbit revealed cavernous sinus thrombophlebitis. Lid sparing partial exenteration was performed. Polymerase chain reaction revealed P. insidiosum. The patient subsequently developed a cerebrovascular attack and died of its complications. Ocular pythiosis may lead to cavernous sinus thrombophlebitis and can even be life threatening. Timely diagnosis and early radical surgery are of value. A high index of suspicion must be kept for P. insidiosum in cases with suspected fungal etiology not responding to conventional treatment.

    Full Text Available Simultaneous cardiac and pericardial rupture from blunt chest trauma is a highly lethal combination with rarely reported survival. We report of a case of young patient with a right atrioventricular groove injury, pericardial rupture and a unique description of a coronary sinus avulsion following blunt chest trauma. Rapid recognition of this injury is crucial to patient survival, but traditional diagnostic adjuncts such as ultrasound, echocardiography and computed tomography are often unhelpful. Successful repair of these injuries requires high suspicion of injury, early cardiac surgery involvement of and possible even placement of the patient on cardiopulmonary bypass.

    To describe MR findings of cerebral venous sinus thrombosis. We reviewed 11 MR images of six patients with cerebral venous sinus thrombosis. The MR images were retrospectively analyzed in terms of location and signal intensity of the thrombi, parenchymal lesions such as hemorrhage and edema, and changes in follow up study obtained in 4 patients. The thrombus in venous sinus was visualized on MRI in all six patients. The most frequently involved sites were superior sagittal sinus(n=4) and left transverse sinus(n=4). Signal intensity of the thrombus was isointense or hyperintense on both T1- and T2-weighted images with loss of normal signal void of the sinus on all sequences in all patients. Parenchymal lesion was patients in five of six cases, manifested as local hemorrhage in three and edema in three cases(one case overlapped). Local edema seen in three patients was completely resolved on follow up study of seven to 29 days intervals. It is concluded that iso- or high signal intensity with loss of signal void in venous sinus is virtually diagnostic of venous sinus thrombosis. If there are local parenchymal lesions such as hemorrhage and/or edema of unknown causes, cerebral venous sinus thrombosis should be included in differential diagnosis

    Assessment of the lateral wall thickness of the maxillary sinus is very important in decision making for many surgical interventions. The association between the thickness of the lateral wall of the maxillary sinus and the dental status is not well identified. To compare the thickness of the lateral wall of the maxillary sinus in individuals with and without teeth to determine if extraction of the teeth can lead to a significant reduction in the thickness of the maxillary sinus lateral wall or not. In a retrospective study on fifty patients with an edentulous space, the thickness of the lateral wall of the maxillary sinus,one centimeter above the sinus floor in the second premolar (P2), first molar (M1) and second molar (M2) areas was determined by cone beam computed tomography scans(CBCTs) and a digital ruler in Romexis F software (Planmeca Romexis 2.4.2.R) and it was compared with values measured in fifty dentated individuals. Three way analysis of variance was applied for comparison after confirmation of the normal distribution of data. The mean of the wall thickness in each of these points was lower in patients with edentulous spaces; however it was not significant. There was no association between gender and the thickness of the lateral wall of the maxillary sinus, but location was associated with different thicknesses. The differences in the thickness based on the location and dental status necessitates assessment of the wall thickness of the maxillary sinus in addition to the current evaluation of bone thickness between the sinus floor and the edentulous crest before maxillary sinus surgery

    Among 4019 computed tomograms of the head performed in 2 years we found 2 epidural empyemas combined with an ipsilateral orbital phlegmon and one periorbital abscess with an incipient orbital phlegmon. In all 3 patients they turned out to be intracranial or orbital complications of an adjacent paranasal sinusitis. The CT diagnosis was a guideline for further therapy and was verified by immediate surgery. The reliable diagnosis of orbital and intracranial spaceoccupying lesions makes CT the radiological method of choice in case of suspicion of a complicated sinusitis.

    An aberrant sinus anatomy or pathology can influence the sinus lift technique if it is encountered during surgical exposure. The purpose of the present study was to determine the prevalence of sinus disease and variations of normal anatomy among edentulous patients prior to sinus augmentation. 120 patients attending a private surgical practice (53 women and 67 men, with a mean age of 62.02 years, ranging between 34 and 81 years old) for whom treatment was planned for sinus augmentation were evaluated--medical history, radiographic and clinical examinations. Computerized tomograms (CT) and 3D reconstructions from 240 sinuses were analyzed using Dental CT. Abnormalities were diagnosed in 74.2% of cases. Mucosal thickening was the most prevalent abnormality (68.3%), followed by retention cysts (15.8%) and opacification (9.2%). The diagnosed conditions included mucosal thickening, chronic sinusitis, sinus cysts and polyps. The prevalence of one or more septa per sinus was found to be 30%. Males present pathology more often than females (p=.028). No statistical correlation could be found between age and pathology (p>0.05) No significant differences in age or gender between patients with and without sinus septum were found (p>0.05). The results reinforce the importance of thorough history taking and clinical and radiographic assessment prior to performing sinus augmentation, to prevent the probability of complications.

    Full Text Available Objective. Sinus floor elevation with lateral approach is probably the most frequently performed reconstructive procedure to rehabilitate posterior maxilla when a bone deficiency is present. Different graft materials have been proposed and tested, often with high clinical performances and predictable results. Histological analysis is required when evaluating new materials. We investigated human biopsies retrieved after sinus floor elevation procedure by histomorphometric evaluation to test the performance of an equine-derived bone grafting material. Study Design. Seventeen consecutive patients were enrolled and sinus lift surgeries were performed using an equine bone graft. Six months after surgery, at implant placement, bone samples were collected. Histomorphometry analysis was carried out on decalcified samples. Results. All surgeries were uneventful and no additional grafting was required prior to implant insertion. Forty percent of new bone formation was detected, which represented the most abundant tissue retrieved, followed by the residual graft material (33% and fibrous tissue (27%. A significant reduction in particles size demonstrates a remodeling activity of the graft material. Conclusion. Within the limitations of this study, this equine-derived bone graft proved to be an effective material to induce new bone formation in the sinus floor elevation procedure.

    Objective: To evaluate the efficacy and risk of endovascular treatment for intracranial venous sinus thrombosis. Methods: Twenty seven patients with intracranial venous sinus thrombosis confirmed by CT, MRI, MRV and/or DSA, from 2004 September to 2006 September, were treated with anticoagulant therapy but without response and then followed by multiple modalities including endovascular treatment. Nineteen of them accepted intravenous thrombolysis and mechanical thrombus maceration, another 5 accepted intravenous thrombolysis, mechanical thrombus maceration and intraarterial thrombolysis and the last 3 with stenting. Results: After thrombolysis, symptoms and signs of 23 patients improved obviously and headache disappeared in 18 of them, but with only mild degree in other 5 and no improvement in 3. Twenty one patients among them achieved recanalization of sinuses completely as confirmed on postprocedural angiography, MRI and MRV studies taken prior to hospital discharge and other 3 achieved recanalization of sinuses partly. Conclusion: Endovascular treatment is an effective and safe measure for potentially catastrophic intracranial dural sinus thrombosis. (authors)

    Perioperative straight sinus thrombosis is extremely rare. A 59-year-old female was admitted to our department because of incidentally found small anterior cerebral artery (A1) aneurysm with microbleeding. After clipping the cerebral aneurysm, she had delayed emergence from anesthesia, total aphasia, and right hemiparesis. Fluid-attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI) of the head showed hyperintensity in the bilateral caudate nuclei, putamina, and thalami, and computed tomography of the head showed a hyperdense straight sinus, suggesting straight sinus thrombosis. Her neurologic symptoms improved gradually, and she achieved a full clinical recovery, with radiological evidence of recanalization of the straight sinus at follow-up. The possibility of straight sinus thrombosis should be considered in postoperative patients with unexplained postoperative deficits when MRI demonstrates hyperintensity in the bilateral basal ganglia and thalami on FLAIR signal images.

    To investigate the risk factors for pilonidal sinus in teenagers. Between January 2013 and September 2015, 55 teenage patients who underwent surgery due to pilonidal sinus disease (PSD) in the Department of Pediatric Surgery, Sakarya University Teaching and Research Hospital were included in this study. Age, gender, body mass index (BMI), number of baths taken per week, time spent sitting per day, family history, and skin color were examined as risk factors. The control group comprised of healthy teenagers without pilonidal sinus disease. Out of the total 42 teenagers, 23 (54.8 %) were girls and 19 (45.2 %) were boys. Patients were classified as obese, overweight, or normal according to their BMI (14.3 %, 31 %, and 54.8 %, respectively). The number of baths taken per week in the PSD group was lower than that in the control group [odds ratio (OR): 3.690; p = 0.004]. The family history of PSD was significantly higher in teenagers with PSD, compared to the control group (OR: 8.652; p = 0.005). No differences were detected between the PSD and control groups with respect to sitting for ≥ 6 h per day (OR: 3.212; p = 0.028). Skin color was not found to be affected by PSD in teenagers (OR: 1.294; p = 0.392). Heredity and the number of baths taken per week were found to significantly affect the incidence of PSD, whereas other variables (gender, age, BMI, skin color, and time spent sitting per day) did not exhibit any significant influence on the rate of incidence.

    Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing's syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88-100% and 67-100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism. Direct stimulation of the pituitary corticotroph with corticotrophin-releasing hormone enhances the sensitivity of the procedure. The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50-70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres. © 2016 The authors.

    2013-12-01

    Operative treatment of calcaneal fractures has a historically high rate of wound complications, so the most optimal operative approach has been a topic of investigation. This study reviews the radiographic and clinical outcomes of the use of the sinus tarsi approach for operative fixation of these fractures with attention to the rate of infection and restoration of angular measurements. The radiographs and charts of 20 patients with 22 calcaneal fractures were reviewed to assess for restoration of angular and linear dimensions of the calcaneus as well as time to radiographic union. Secondary outcome measures included the rate of postoperative infection, osteomyelitis, revision surgeries, and nonunion. We found a statistically significant restoration of Böhler's angle and calcaneal width. Three of the 22 cases had a superficial wound infection. One patient had revision surgery for symptomatic hardware removal. There were no events of osteomyelitis, deep infection, malunion, or nonunion. We found that the sinus tarsi approach yielded similar outcomes to those reported in the literature. Level IV, retrospective case series.

    This review discusses the incidence, pathogenesis, risk factors, diagnosis, and therapeutic options for persistent perineal sinus (PPS), defined as a perineal wound that remains unhealed more than 6 months after surgery. The incidence of PPS after surgery for inflammatory bowel disease (IBD) ranges from 3% to 70% and after abdominoperineal resection (APR) for Low rectal cancer, it can be up to 30%. These unhealed wounds are frequently related to perioperative pelvic or perineal sepsis. Crohn's disease (CD) and neoadjuvant radiation therapy are also important risk factors. The management of PPS is based on an understanding of pathogenesis and clinical grounds. The advantages and disadvantages of the current therapeutic approaches, including the topical administration of various drugs, vacuum-assisted closure, and perineal reconstruction with a muscle flap or a myocutaneous flap are also discussed.

    Maxillary sinus carcinomas are rare malignancies of the face, characterized by high local relapsing rate. Modalities of treatment are without consensus and respective roles of radiation therapy and surgery remain controversial. As those malignancies are often diagnosed at locally advanced stage, radiation therapy may frequently be used for patients having unresectable advanced disease. Nevertheless, surgery remains treatment of choice for more localized malignancies, in association with systematic postoperative radiotherapy. For those patients whose prognosis remains pejorative, it is necessary to precise the role of radiotherapy in first intention for inoperable tumors, to define necessity for nodal treatment performing and evaluate the place of neo-adjuvant or concomitant chemotherapy in a multimodal strategy.

    Ameloblastoma is a benign aggressive odontogenic tumor which requires early diagnosis and appropriate treatment. It commonly affects the mandible and radical surgery is the gold standard treatment. We report the case of a patient with ameloblastoma in extremely advanced phase affecting the maxillary sinus who was treated with intensity modulated conformal radiation therapy. Patient's evolution was marked by complete remission maintained after 24 months follow-up. Maxillary ameloblastoma is not well documented in the literature. It is usually diagnosed at the later stage when optimal surgery cannot be performed. This case study aimed to demonstrate that radiation therapy is a real therapeutic alternative in the treatment of advanced and inoperable forms of ameloblastoma.

    2009-12-01

    To study the etiopathogenesis, clinical features, diagnosis and treatments of monostotic fibrous dysplasia of the sphenoid sinus. Two cases of monostotic fibrous dysplasia of the sphenoid sinus without any symptoms was reported with relevant literature review. No aggravation was found after 6 months-follow-up. The cranial fibrous dysplasia has low incidence rate with non-specific symptoms and high rate of misdiagnosis. The monostotic fibrous dysplasia of the sphenoid sinus without any symptom is rarely seen clinically. Imagiological examination, for example, CT and MRI, is valuable for the diagnosis of this disease. The histopathological evidence is absolutely necessary to make definite diagnosis. The conservative treatment may be chosen for the asymptomatic cases. Nasal Endoscopic surgery can not only remove the diseased region but also make diagnosis. The long-term follow-up should be carried out in all of these patients.

    To examine the three-dimensional virtual anatomical features of the sphenoid sinus and adjacent structures during virtual surgery and explore their relevance to actual transsphenoidal surgery. CT images of the sphenoid sinus and surrounding structures from 28 Chinese adult patients were measured using a 16-slice helical CT scanner. Image analysis was performed using the volume-rendering method. Two experienced neurosurgeons wearing stereoscopic glasses performed virtual transsphenoidal surgery by the transnasal approach. The virtual anatomical features of the sphenoid sinus and the adjacent structures during virtual surgery were described. The distance from the sphenopalatine foramen to the left and right sphenoid ostium was 10.1 ± 2.7 mm and 10.5 ± 3.2 mm, respectively, to the left and right sphenoidal crest 12.9 ± 2.0 mm and 12.8 ± 2.2 mm, respectively, and to the left and right uncinate process 24.0 ± 1.9 mm and 23.9 ± 2.0 mm, respectively. The distance from the uncinate process to the medial and lateral edge of the most prominent part of the anterior bend of the cavernous internal carotid artery (ICA) was 33.7 ± 3.7 mm and 34.8 ± 3.7 mm, respectively, and the angle between the two lines was 9.7 ± 1.9°. The study provides virtual anatomical information about the sphenoid sinus and important surrounding structures that is essential for successful real life transsphenoidal surgery.

    Purpose Paranasal sinusitis is widespread and can lead to orbital complications, blindness, and death. However, the correlation between ophthalmological findings and disease staging remains unclear. This study aimed to investigate the staging, acute ophthalmological manifestations, diagnosis, management, and outcomes of orbital complications of paranasal sinusitis during a 27-year period. Methods We retrospectively reviewed the medical records of all patients with orbital complications of paranasal sinusitis hospitalized at the National Cheng Kung University Hospital, a medical center in Taiwan during 1988–2015. Sex, age, symptoms, history, ophthalmological findings, laboratory and imaging findings, treatments, and outcomes were analyzed by staging. Results Eighty-three patients aged 9 days to 80 years had stage I (preseptal cellulitis, n = 39 patients), II (postseptal orbital cellulitis, n = 8), III (subperiosteal abscess, n = 16), IV (orbital abscess, n = 8), or V (intracranial involvement, n = 12) complications. Peak incidences occurred in patients aged 0–19 and 60–69 years. Chronic sinusitis and diabetes mellitus were common preexisting diseases. Extraocular movement limitation and proptosis predicted postseptal (stage II or more) involvement. The likelihood of elevated intraocular pressure increased with stage. Reduced visual acuity and presence of relative afferent pupillary defect indicated consideration of magnetic resonance imaging to investigate possible intracranial extension. Ipsilateral maxillary (81.7%) and ethmoidal (75.6%) sinuses were the most common sources of infection, and the most frequently implicated pathogens were coagulase-negative Staphylococcus spp. (25.3%) and Staphylococcus aureus (20.5%). All patients received intravenous antimicrobial therapy (multi-drug therapy in 88.0%), and 55.4% underwent surgery, most commonly endoscopic sinus surgery.

    Full Text Available The aim of this cross-sectional in vitro study was to evaluate the mucosal surfaces of healthy maxillary sinuses, explore different forms of bacterial microorganism colonies present on the mucous membrane, and determine a mucosal surface area they occupy.Samples of the maxillary sinus mucosa were collected from 30 healthy patients (M = 11; F = 19. The material was obtained during the Le Fort I osteotomy performed during corrective jaw surgery. The morphological and morphometric analysis of sinus mucosa and bacterial film that was grown on it was performed using scanning electron microscopy (SEM as well as imaging software.Scanning electron microscopy analysis showed the presence of different bacterium and bacteria-like structures in all the analyzed samples. In most cases, the bacterial film was mostly composed of diplococci-like and streptococci-like structures on the mucosa of the paranasal sinus. In any case, the mucous layer did not cover the whole lining of the evaluated sample. Each colony consists of more than 20 single bacterial cells, which has grown in aggregates.Under the conditions of normal homeostasis of the body, the maxillary sinuses present diverse bacterial colonization. The bacteria are dispersed or concentrated in single microcolonies of the biofilm on the border of the mucous covering the ciliary epithelium. There is no uniform layer of the biofilm covering the mucosa of the maxillary sinuses. Because the biofilm is detected on healthy individuals sinus mucosa, the clinical question if it may become pathogenic is unclear and require an explanation.

    2015-01-01

    Background The aim of this study was to simulate implant placement in the maxillary sinus septum, as a potential alternative site to avoid sinus grafting. Material/Methods One hundred partially or completely edentulous patients, with their maxillary sinus septum present in the edentulous region, were selected from the database of the Department of Maxillofacial Surgery, Cliniques Universitaires Saint Luc, Bruxelles, Belgium. Three-dimensional (3D) reconstructions were created using 3D planning software. 3D reconstructions were performed for each maxillary sinus. Using the software implant library, the implants that presented the best fit with the maxillary sinus septum and that followed the established inclusion criteria were selected. Results All of the implants were inserted in premolar and molar regions. Most implants were inserted in the position of the second molar (21 of 55) or in the position of the first molar (17 of 55). In all sites the most frequently used implant was 4 mm in diameter and 7 mm in height. The mean coronal angle for the implant was 80.19±17.13 degrees and the mean sagittal angle was 94.83±9.94 degrees. The septal height represents 38.13% of the total available bone height (ABH). The mean percentage of the septum used to insert the implants was 47.33±2.47%. The septum increased the available bone height by a mean value of 2.18±1.47 mm. In 45 cases, the septa did not permit implant placement. Conclusions In completely edentulous patients, inserting implants in sinus septa does not exclude the need for sinus grafting, but in partially edentulous patients, this minimally invasive technique is an alternative to subantral augmentation.

    Background The aim of our study was to investigate, in 3 dimensions, the maxillary sinus septa as an alternative site for dental implant placement to avoid sinus lift procedures. Material/Methods We selected 100 dentate and 100 edentate patients with the presence of a maxillary sinus septum by reviewing a larger cone beam computer tomography (CBCT) database from the Department of Oral and Maxillofacial Surgery at Cliniques Universitaires Saint Luc in Bruxelles, Belgium. Three-dimensional reconstructions of 200 maxillary sinus septa were performed using Maxilim software. Ten measurements (length, lateral height, and thickness of the middle and medial region of the septum) were performed by 1 observer, 2 times, with an interval of 1 week between measurements. The angle between the septum and the maxillary plane was also measured. Finally, localization and orientation were assessed for each septum. Results There was no statistically significant difference between the 2 intraobserver measurements (p>0.05). Student’s t-test was used to compare means. Middle height was the only measurement for which there was a difference between edentate and dentate patients (p=0.0095, edentate mean < dentate mean). The location of the septa observed in our study groups demonstrated greater prevalence in the posterior region than in the anterior and middle regions. For the spatial orientation of the septum, we found that most septa (81.2% in dentate patients, 53% in edentate patients) were oblique. Conclusions Three-dimensional evaluation of maxillary sinus septa using 3D CBCT imaging showed that the sinus septum could offer an alternative site for implant placement in the maxillary sinus.

    Objective: A description is made of transcrestal sinus lift using the sinus balloon technique, evaluating the bone height achieved and implant success one year after prosthetic loading. Material and method: Between January and July 2007, transcrestal sinus lift using the sinus balloon technique for dental implant placement was carried out in 6 patients. A panoramic X-ray study and maxillary computed tomography scan were carried out before the operation, in order to discard possible sinus pathology. During the intervention, the integrity of the sinus membrane was evaluated using a Medi Pack Pal endoscope (Farol Store and Co., Tuttlingen, Germany), and the intraoperative complications were analyzed. The dental implants were placed in the same surgical step in the presence of 3 mm or more of residual bone. Following the operation, panoramic X-rays were used to assess the bone height gained. One year after prosthetic loading, the implant success rate was determined based on the criteria of Buser. Results: One patient was excluded due to Schneider’s membrane perforation as confirmed by endoscopy. Trans-crestal sinus lift was carried out in 5 males with a mean age of 41.6 years (range 27-51), without antecedents of sinus disease. There were no intraoperative complications. In four patients the implants were placed simultaneous to sinus lift, while in another case implant placement was postponed due to insufficient remaining bone height. The mean gain in height after the operation was 8.7 mm. One year after prosthetic loading, the implant success rate was 100%. Conclusions: Transcrestal sinus lift using the sinus balloon technique is a minimally invasive procedure. In 5 patients the bone height gained proved sufficient to allow implant placement even in the presence of 3 mm of residual bone. Key words: Sinus lift, balloon, sinus complications. PMID:22157670

    Full Text Available Background: Pilonidal disease occurs either as a secreting sinus or in the form of an acute abscess in the coccygeal area and is an underlying cyst associated with granulomatous and fibrosis tissue which commonly contains heaps of hair, for which inherited and acquisitive hypotheses are proposed. Body mass index (BMI is the objective indicator of obesity according to height and weight. This study aims to examine the relationship between BMI and the role of obesity in development and relapse of pilonidal cyst disease.Materials and Methods: This retrospective cross-sectional study examined 126 patients with primary or recurrent pilonidal sinus within a year. A separate questionnaire was formed and recorded in the computer for each patient based on the disease type and body mass index.Results: One hundred out of 126 studied patients (79.4% underwent primary Pilonidal Sinus surgery and 26 patients (20.6 had recurrent Pilonidal sinus surgery. 36 patients (28.6 were female and 90 patients (71.4% were male. Among patients with recurrent Pilonidal sinus, 18 patients (69.2% had BMI above 30 and 8 patients (30.8% had BMI of 25 to 30 kg/m2. The patients whose BMI was estimated to be 20 to 25 or less than 20 kg/ m2 per square meter, had no recurrence of disease. Conclusion: In this study, high BMI was associated with relapse of pilonidal sinus disease. Supporting the previous studies, the incidence of disease in this study was also higher in young adults.

    Background Chronic recurrent sinusitis (CRS) is an inflammatory disease of the facial sinuses and nasal passages that is defined as lasting longer than 12 weeks or occurring more than 4 times per year with symptoms usually lasting more than 20 days. The National Institute for Health Statistics estimates that CRS is one of the most common chronic conditions in the United States affecting an estimated 37 million Americans. The potential etiologies of CRS include bacteria, viruses, allergies, fungi, superantigens and microbial biofilms. In clinical practice there is a significant subpopulation of patients with CRS who remain resistant to cure despite rigorous treatment regimens including surgery, allergy therapy and prolonged antibiotic therapy. The reason for treatment failure is thought to be related to the destruction of the sinus mucociliary defense by the chronic sinus infection resulting in the development of secondary antibiotic resistant microbial colonization of the sinuses and biofilm formation. Antimicrobial photodynamic therapy (aPDT) is a non-antibiotic broad spectrum antimicrobial treatment that has been demonstrated to eradicate antibiotic resistant bacteria and biofilms. Objective The objective of this study was to demonstrate the effectiveness of a non-invasive aPDT treatment method of eradicating antibiotic resistant biofilms/microorganisms known to cause CRS in an in vitro model. Methods Antibiotic resistant planktonic bacteria and fungi and polymicrobial biofilms of Pseudomonas aerugenosa and MRSA were grown on silastic sheets and treated with a methylene blue photosensitizer and 670nm non-thermal activating light. Cultures of the planktonic micoroorganisms and biofilms were obtained before and after light treatment to determine efficacy of planktonic baciteria and biofilm reduction. Results The in vitro CRS planktonic microorganism and biofilm study demonstrated that aPDT reduced the CRS polymicrobial biofilm by >99.9% after a single treatment

    Full Text Available Pilonidal sinus is a term first used by Hodges in 1880 to describe granulomatous lesions containing hairs in its interior. The presence of endoanal pilonidal sinus is rare and only nine cases have been reported in medical literature. This article describes a male, 42 years, initially submitted to fistulotomy with seton placement that four years later evolved with complaints of anal purulent discharge associated with painful anal groin. During the first evaluation a small endoanal tumor was found. It was located in posterolateral anus position and contained hair in its interior, without purulent discharge at that moment. Underwent surgery that confirmed the presence of endoanal pilonidal sinus. The sinus was opened and left to heal by secondary intention. The patient had good outcome with no signs of recurrence. Resumo: O termo cisto pilonidal foi descrito pela primeira vez por Hodges em 1880 para descrever lesões granulomatosas contendo pêlos em seu interior. A presença de cisto pilonidal endoanal é rara e existem apenas nove casos relatados na literatura médica. Descreve-se um caso masculino, 42 anos, em acompanhamento há 5 anos no serviço. Submetido inicialmente à fistulotomia em dois tempos com sedenho, evoluindo 4 anos depois com queixas de secreção purulenta intermitente por via anal associada a presença de tumoração dolorosa. No exame físico constatou-se presença de orifício contendo pêlos em seu interior, sem secreção purulenta no momento do exame. Foi encaminhado para tratamento cirúrgico que confirmou diagnóstico de cisto pilonidal endoanal. No procedimento foi realizada abertura do cisto que foi deixado para cicatrizar por segunda intenção.

    This article presents long-term treatment results by analyzing 24 cases with adenoid cystic carcinoma (ACC) of the nasal and paranasal sinus treated from 1975 to 1995 at Akita University Hospital and Chiba University Hospital. The basic strategies for treatment for ACC of the nasal and paranasal sinuses are en bloc tumor resection, followed by primary reconstruction of the maxilla. Preoperative and postoperative radiation were combined. Cumulative 5-year and 10-year survival rates were 70.6% and 47.1% for maxillary sinus tumors, respectively. Cumulative 5-year and 10-year survival rates for nasal tumors were 100% and 75.0%, and those for sphenoid sinus tumors were 50.0% and 0%, respectively. The patient with ethomoid sinus who needed skull base surgery is alive at 8.1 years after therapy. Treatment results closely correlated with tumor extension. Cumulative 5-year survival rates for T2, T3 and, T4 patients with maxillary sinus tumors were 85.7%, 71.4%, and 33.3%, respectively. And cumulative 10-year survival rates for T2, T3, and T4 were 71.4%, 42.9%, and 0%, respectively. The histopathological effects of preoperative radiation were Shimosato II a in 6 out of 10 patients, II b in 2, and III in 2, respectively. Only fast neutron therapy reached Shimosato III. Two of the patients with Shimosato II a died of distant metastasis. The above data suggests that, although radiation therapy alone cannot cure tumors, preoperative full-dose radiation may prevent the development of distant metastasis if it can achieve histopathological effects of a higher classification than Shimosato II b. Because chemotherapy and radiation is not very effective on ACC, the role of skull base surgeries for nasal-paranasal sinus malignancies that invade the skull base is valuable, particularly in cases having a relatively small mass in the ethmoid sinus.

    Endoscopic transethmoidal sphenoidotomy performed mainly in the early stages of the pathology and by expert hands is [WX1]very effective in treating isolated sphenoid sinus disease. This study aimed to investigate the causes of isolated sphenoid sinus disease identified in 109 patients and report on the most appropriate diagnostic and therapeutic patterns for an earlier diagnosis and a successful treatment of the disease. A total of 109 subjects with various isolated sphenoid pathologies were first examined by general objective examination, nasal sinus endoscopy, CT scan of paranasal sinuses, and in some cases with MRI. Then, they underwent medical and/or surgical treatment. Nineteen patients (17.43%) had isolated sphenoiditis, 6 (5.5%) fungal sinusitis, 30 (27.52%) mucocele, 6 (5.5%) fibrous dysplasia, 6 (5.5%) meningoencephalocele, 5 (4.58%) inverted papilloma, 4 (3.66%) epidermoid carcinoma, 10 (9.17%) liquor fistula, 1 (0.9%) rhabdomyosarcoma, 1 (0.9%) chordoma, and 1 (0.9%) had carotid pseudoaneurysm. Evidence of definitive diagnosis by endoscopy was obtained in less than half of the cases. CT scan, however, sometimes in combination with MRI, determined the pathology in all the cases. A follow-up of at least 4 years post-surgery showed good results in all the patients who underwent endoscopic transethmoidal sphenoidotomy.

    To investigate the frequency and effective treatment of ulcers and sinuses in cases of tuberculous cervical lymphadenitis (TCL). Observational cross-sectional study. Department of ENT, Head and Neck Surgery of Tribhuvan University Teaching Hospital (TUTH), Kathmandu, Nepal, during the period of two years from March, 2000 to February, 2002. A hundred cases of histopathologically confirmed cases of tuberculous cervical lymphadenitis of more than six weeks of duration were included in the study. Overall frequency of the complication as well as the efficacy of treatment regime was considered. Out of 100 patients, 8 (8%) were found to develop ulcers and/or sinuses during the process of development of TCL which were effectively treated (100% cure rate). Mode of treatment was surgical excision of ulcers/sinuses along with affected underlying lymph nodes, followed by short course of anti-tubercular chemotherapy. Not a single case recurred during their follow-up period. In this series there was a low frequency of formation of ulcers/sinuses during the process of development of TCL. Surgical excision of ulcers/sinuses along with affected underlying lymph nodes, followed by short course of anti-tubercular chemotherapy is the effective methods of their treatment.

    The aim of the present study is to evaluate the use of anorganic bovine bone (ABB) associated with a collagen membrane (CM) for a sinus graft by means of clinical, histologic, and radiographic parameters in cases with bone availability 406 sinuses) participated in this study. A total of 1,025 implants were placed in the grafted sinuses. A total of 118 implants were placed simultaneously with the sinus graft (one stage), and 907 implants were placed in a subsequent surgery (two stages), 6 to 12 months after the graft was performed. In seven cases, a biopsy was harvested for histomorphometric analysis. Recall appointments were scheduled every 6 months, and panoramic and periapical x-rays were required every year for 3 years. Among 1,025 implants, 19 were lost (survival rate: 98.1%). The difference in survival rates for implants placed in native bone 3 to 5 to < or =7 mm (97.0%) was not statistically significant (P = 0.3408). The survival rates for implants with rough and machined surfaces (98.6% and 97.0%, respectively) were not statistically significant (P = 0.0840). The histomorphometric analysis showed new bone formation (39.0% +/- 12%), marrow space (52.9% +/- 9.3%), and residual ABB (8% +/- 2.7%). Our results indicated that 1,025 implants placed in sinuses grafted exclusively with ABB combined with CM led to an excellent and predictable survival rate of 98.1%.

    2008-12-01

    Full Text Available Introduction: Mucormycosis is a rare opportunistic infection caused by Mucorales fungi, and the Rhizopus is the most common one (70% of the cases. It is an acute invasive fungal disease whose form is disseminated, cutaneous, pulmonary, gastrointestinal and rhino-orbitocerebral. The latter is the most common form and its symptoms comprise of unilateral sinusitis, fever and headache. Once established in the orbit the symptoms can be chemosis, diplopia and reduced vision. The infection can spread to the brain via the orbital apex, orbital arteries or via the cribriform plate. Mucormycosis is a medical emergency and the treatment consists of a surgery to an aggressive debridement and in the use of antifungal therapy. Despite the appropriate management, the mortality rate can reach 40% of the cases. One possible intracranial complication of Mucormycosis is the Cavernous Sinus Thrombosis which is a rare and fatal infective disease. The initial symptoms of Cavernous Sinus Thrombosis are headache, retro-orbital pain, periorbital edema, proptosis, diplopia and reduced vision. Case Report: We describe the case of 43-year-old woman with medical history of diabetes mellitus and use of immunosuppressant drugs after kidney transplantation. The patient developed Acute Bacterial Sinusitis and Rhino-orbitocerebral Mucormycosis associated with Cavernous Sinus Thrombosis.

    It is universally accepted that osteomeatal complex (OMC) disease is linked to the subsequent development of chronic rhinosinusitis without nasal polyps (CRSsNPs) via postobstructive mechanisms. The role of OMC obstruction in the pathogenesis of CRSwNPs is less clear. This study was designed to identify if there is an association between OMC obstruction and inflammation of the adjacent sinuses, when patients are stratified by polyp status. This is a follow-up and expanded series of a previous pilot study from our group. CT scans of 144 patients with CRSsNPs and 123 patients with CRS with nasal polyps (CRSwNPs) were evaluated for each sinus and OMC. Patients had no previous surgeries for NPs. CT scans were obtained after a trial of maximal medical therapy. Increasing OMC involvement was associated with increasing Lund-Mackay score for both CRSsNPs and CRSwNPs. In CRSsNP patients, OMC status significantly correlated with adjacent sinus status (p OMC status does not correlate with adjacent sinus status (p = 0.328). OMC obstruction in the setting of CRSwNP may be a barometer of the overall disease process, but in this scenario, paranasal sinus inflammation can not be classified as a postobstructive phenomenon. These findings question the role of minimally invasive procedures in the management of CRSwNPs.

    Dermal sinus tracts are rare congenital lesions located in the midline characterized by a cutaneous pit or dimple. They occur all along the midline neuroaxis, from the nasion and occipital area down to the lumbar and sacral regions, most frequently in the lumbar and lumbosacral region. Here we report a 5-year-old girl who presented with occasional headache. There were two dimples, one on the dorsal aspect of her head and another on her neck. Dermal sinuses are almost always singular and the co-existence of double dermal sinuses has not been reported previously.

    2005-02-01

    Objective: Our aim was to determine whether inward or outward movement of the secretions in the paranasal sinuses due to nose blowing after nasal decongestion has any effect on the paranasal sinus computed tomography (CT) images in patients with sinusitis and to asses whether nose blowing may result in misdiagnosis or overdiagnosis in radiological evaluation of sinusitis. Materials and methods: Twenty-four patients with chronic sinusitis were evaluated in an academic tertiary care hospital and data were collected prospectively. After coronal sinus computed tomography scans were performed at 100 mA setting which was half the value of the standard radiation dose suggested by the manufacturer, topical decongestion was applied to each nostril followed by nose blowing 10 min later. Sinus CT scans were then repeated at the same setting. We evaluated the mucosal thickness of medial, lateral, superior and inferior maxillary and frontal sinus walls and the maximal thickness in anterior ethmoidal cells. The measurements prior to and following nose blowing were compared with Wilcoxon signed ranks test. The obtained images were also staged using Lund-McKay staging system separately and the scores were compared with Student's t-test. Results: We observed a tendency towards reduction in mucosal thickness after nose blowing. There were statistically significant differences between maxillary sinus inferior wall and frontal sinus inferior wall mucosal thickness values prior to and after nose blowing. The difference however was very small, about 0.5 mm in magnitude and Lund-McKay score did not change in any of the patients after nose blowing. Conclusion: Nose blowing and topical nasal decongestion does not have any effect on the diagnostic accuracy of sinus CT in chronic sinusitis patients.

    This study was performed to compare paranasal sinus tomosynthesis with computed tomography (CT) imaging as a radiologic tool to evaluate the paranasal sinuses, using measurement of the soft tissue thickness of the maxillary sinus. A total of 114 patients with sinusitis who underwent both paranasal sinus digital tomosynthesis (DT) and CT were enrolled in this retrospective study. Two observers independently assessed soft tissue thickness in both maxillary sinus chambers using both DT and CT images. The mean difference in soft tissue thickness measured by each observer was −0.31 mm on CT and 0.15 mm on DT. The mean differences in soft tissue thickness measured with DT and CT were −0.15 by observer 1 and −0.31 by observer 2. Evaluation of the agreement in measurement of soft tissue thickness in the maxillary sinus using DT and CT showed a high intraclass correlation, with the 95% limit of agreement ranging from −3.36 mm to 3.06 mm [intraclass correlation coefficient (ICC), 0.994: p<0.01] for observer 1 and from −5.56 mm to 4.95 mm (ICC, 0.984: p<0.01) for observer 2. As an imaging tool, DT is comparable to CT for assessing the soft tissue thickness of maxillary sinuses in patients with sinusitis.

    Full Text Available The objective of this study is to report a clinical case of maxillary sinus with lyophilized, xenogeneic graft, in which, despite a large perforation of the sinus membrane, the surgery was not aborted and the results of histological examinations indicate bone neoformation in the surgical area. Results. This case showed that the biomaterials evaluated in this study and the procedure used to place them proved to be biocompatible and presented high osteogenic potential, leading to a successful surgery and osseointegration implant. Conclusion. Positioning Schneider’s membrane and filling it with the graft biomaterial helped to achieve the desired osteoconduction and proliferation of bone cells even though the patient had a large perforation of the sinus membrane.

    Full Text Available Objectives. Organized hematoma (OH is a rare, nonneoplastic, hemorrhagic lesion causing mucosal swelling and bone thinning, mainly in the maxillary sinus. We aimed to clarify the clinical presentation and treatment of OH. Methods. Three cases of maxillary sinus OH and a literature review are presented. Results. Three men aged 16–40 years complained of nasal obstruction, frequent epistaxis, and/or headache. Clinical and radiological examinations revealed a maxillary sinus OH. They were cured in a piecemeal fashion via endoscopic middle meatal antrostomy. Furthermore, vascular endothelial growth factor and its receptor were expressed in the lesion. Conclusions. The pathogenesis of OH is unclear and it presents various histological and imaging findings; however, it is not difficult to rule out malignant tumors. Minimally invasive surgery such as endoscopic sinus surgery can cure it completely. Thus, it is important to determine the diagnosis using CT and MRI and to quickly provide surgical treatment.

    2017-05-01

    Rhinitis and sinusitis usually coexist and are concurrent in most individuals; thus, the correct terminology is now "rhinosinusitis". On the basis of numerous causative factors, often co-existing in the same patient, the diagnosis of rhinosinusitis is also made by a wide variety of practitioners (allergologists, otolaryngologists, pulmonologists, primary care physicians, paediatricians, and many others). Approximately 5-15% of the population suffers from chronic rhinosinusitis, and in 10-12% of them, it is of dental origin. The treatment of odontogenic maxillary sinus disease is directed to the management of the rhinosinusitis and of the odontogenic source. The widespread use of dental implants and reconstructive procedures for dental implant placement has led to new types of complication, as in this case report, due to chronic eosinophilic rhinosinusitis secondary to Fusarium infection in the maxillary sinus. The patient was initially evaluated by the allergologist, and subsequently successfully treated by the otolaryngologist with Functional Endoscopic Sinus Surgery. The advantages of endoscopic sinus surgery include more accurate visualization, no external incision, reduced soft tissue dissection, and reduced hospital stay. Chronic maxillary sinusitis of dental origin is a common disease that requires treatment of the sinusitis as well as of the odontogenic source.

    Fibrous dysplasia is an uncommon benign bone disorder of unknown etiology in which normal medullary bone is replaced by fibrotic and osseous tissue. Solitary involvement of the sphenoid sinus is unusual. Here, we present the case of a 28-year-old man complaining of occipital and vertical headache. Imaging modalities demonstrated an expansile lesion filling the entire sphenoid sinus. Biopsy specimen was obtained by endoscopic sphenoidotomy. Diagnosis of fibrous dysplasia was made by imaging results and pathologic examination.

    Sinusitis of odontogenic origin, which is frequently encountered in routine otolaryngological and dental clinical practice, has been described as a reactive maxillary inflammation secondary to maxillary tooth infection or trauma to an odontogenic disease of maxillary bone, dental extractions, implant placement, or endodontic treatment impairing the integrity of the Schneiderian membrane. The aim of the present review was to investigate and discuss the most recent pathophysiological findings, predisposing odontogenic factors, microbiology, and the possible involvement of bacterial biofilms (BB) in the development of sinusitis. The narrative literature review showed that there might be a correlation between the bacteria present in pathological teeth in communication with the sinus and those found in infected sinus. The formation of a BB might be also involved in the etiopathogenesis of sinusitis of odontogenic origin. In conclusion, the true origin of odontogenic sinusitis is still unresolved. In clinical terms, the choice of suitable therapy depends on the characteristics of the biofilm. Further microbiological studies are required to better investigate the role of BB. © 2015 Wiley Publishing Asia Pty Ltd.

    Studying the three-dimensional (3D) anatomy of the cavernous sinus is essential for treating lesions in this region with skull base surgeries. Cadaver dissection is a conventional method that has insurmountable flaws with regard to understanding spatial anatomy. The authors' research aimed to build an image model of the cavernous sinus region in a virtual reality system to precisely, individually and objectively elucidate the complete and local stereo-anatomy. Computed tomography and magnetic resonance imaging scans were performed on 5 adult cadaver heads. Latex mixed with contrast agent was injected into the arterial system and then into the venous system. Computed tomography scans were performed again following the 2 injections. Magnetic resonance imaging scans were performed again after the cranial nerves were exposed. Image data were input into a virtual reality system to establish a model of the cavernous sinus. Observation results of the image models were compared with those of the cadaver heads. Visualization of the cavernous sinus region models built using the virtual reality system was good for all the cadavers. High resolutions were achieved for the images of different tissues. The observed results were consistent with those of the cadaver head. The spatial architecture and modality of the cavernous sinus were clearly displayed in the 3D model by rotating the model and conveniently changing its transparency. A 3D virtual reality model of the cavernous sinus region is helpful for globally and objectively understanding anatomy. The observation procedure was accurate, convenient, noninvasive, and time and specimen saving.

    To evaluate the computed tomographic appearances of postoperative maxillary sinuses. 33 asymptomatic cases of post-operative maxillary sinus without evidence of any pathologic changes and clinical symptoms were selected. CT images were classified as opacification, soft tissue shadow, anterior wall depression, nasoantral communication, and compartmentalization. The relationships between the CT image and the age of patients at the time of operation, and between the CT image and the duration of time elapsed since the surgical procedure were evaluated. The most commonly presented radiological characteristics that occurred after the Caldwell-Luc procedure were opacification and soft tissue shadow. Anterior wall depression and nasoantral communication were radiographic indications that a Caldwell-Luc operation had been carried out. The age of patients when they had been first operated on, and the duration between the surgical procedure and the time of evaluation had no effect on the CT appearances of normal changes. In cases involving a longer time interval between the antral surgery and evaluation, the anterior wall depression with bony healing was more commonly observed than soft tissue healing. The radiographic information regarding the normal healing state using computed tomography can distinguish post-operative changes from inflammatory and cystic disease in patients who have undergone a Caldwell-Luc type of radical maxillary astronomy.

    Three horses, a 10-year-old Thoroughbred mare, a 9-year-old Thoroughbred gelding and a 6-year-old Arab gelding, with calcified tumours of the paranasal sinuses, are described. All horses presented with purulent nasal discharges and facial distortion. Exophthalmos, blepharospasm and ocular discharge were also a feature in individual horses. A presumptive diagnosis of a calcified tumour was made on the basis of clinical signs and radiographic and endoscopic findings. The tumours ranged from 15 to 25 cm in diameter. A large frontonasal bone flap was used to expose the tumours, which were cleaved into several pieces with an osteotome and removed. Histological examination of the masses identified cementomas in two cases and an osteoma in the third. Long term follow up from 18 months to 5 years after surgery indicated that there was no recurrence. This case series demonstrates that, although calcified tumours of the paranasal sinuses are rare in horses, they should be considered in the differential diagnosis of purulent nasal discharge, facial swelling and ocular distortion, and are amenable to surgical treatment.

    Studies on the interaction of magnetic fields and biological organisms have centred on the influence of applied magnetic fields on the physiology and behaviour of organisms, including humans, and a search for magnetic sources within the organisms themselves. Evidence continues to accumulate that a wide range of organisms, from bacteria to vertebrates, can detect and orient to ambient magnetic fields (for examples see refs 2-4). Since the discovery that magnetic orientation by bacteria was due to the presence within the organism of magnetic particles of the ferric/ferrous oxide, magnetite, the search has begun for other biogenic deposits of inorganic magnetic material and ways in which the possession of such material might confer on the organism the ability to orient to ambient magnetic fields. Such magnetic material, often identified as magnetite, has been discovered in bees, homing pigeons, dolphins and various other organisms, including man. A variety of hypotheses for the use of magnetite in magnetic field detection have been proposed. We report here that bones from the region of the sphenoid/ethmoid sinus complex of humans are magnetic and contain deposits of ferric iron. The possible derivations and functions of these deposits are discussed.

    This study sought to investigate the proportion of patients with suspected sinusitis referred for radiological examination who have radiologically verified sinusitis of odontogenic origin and to describe this type of sinusitis. This investigation is a retrospective study. A total of 303 sinus examinations involving cone beam computed tomography (CBCT) performed at Sunderby Hospital, Luleå, Sweden in 2012 were independently reviewed by two radiologists. The number of cases of maxillary sinusitis and the correlation between maxillary sinusitis and odontogenic infections were determined. Overall, 24% of the verified cases of sinusitis were odontogenic. An odontogenic origin was identified in 40% of unilateral maxillary sinusitis cases but only 6% of bilateral maxillary sinusitis cases ( p  = 0.0015). Forty-nine out of 54 patients with periapical destruction had adjacent mucosal swelling in the maxillary sinus, but only 15 of these patients satisfied the criteria for sinusitis. The present study confirms the close relationship between odontogenic infections and unilateral maxillary sinusitis. Level of Evidence 4.

    Fibrous dysplasia involving paranasal sinuses mostly has asymptomatic features, but sometimes may cause signs and symptoms which relate to the location and extent of bony abnormalities. The use of endoscopic nasal surgery for debulking ethmoidal fibrous dysplasia, blocking the left nasolacrimal sac and simultaneous intranasal endoscopic dacryocystorhinostomy with silicone intubation is presented. The procedure and advantages of endoscopic approach over the external approach are outlined in this paper.

    Full Text Available Ruptured sinus of Valsalva aneurysm is a rare anomaly and an associated coarctation of aorta is even rarer. A combination of such defects is traditionally treated surgically. The surgery is necessarily staged and done through different approaches. We report successful simultaneous transcatheter treatment of both these defects performed in the same setting in an acutely ill adult male patient with a good intermediate-term follow-up.

    Visual disturbances associated with isolated sphenoid sinus inflammatory diseases (ISSIDs) are easily misdiagnosed due to the nonspecific symptoms and undetectable anatomical location. The main objective of this retrospective case series is to investigate the clinical features of visual disturbances secondary to ISSIDs. Clinical data of 23 patients with unilateral or bilateral visual disturbances secondary to ISSIDs from 2004 to 2014 with new symptoms were collected. Collected data including symptoms, signs, neuroimaging and pathologic diagnosis were analyzed. There were 14 males and 9 females, and their ages ranged from 31 to 83 years. Fifteen patients suffered blurred vision and 11 patients suffered binocular double vision, including 3 patients who had unilateral visual changes and diplopia simultaneously. Headache was observed in 18 patients, and orbit pain/ocular pain in 8 patients. Other presenting symptoms included ptosis (4 patients) and proptosis (1 patient). Only 5 patients had nasal complaints. The corrected visual acuities were between NLP to 20/20. Patients with diplopia included 5 with unilateral oculomotor nerve palsy and 6 with unilateral abducens nerve palsy. All patients performed orbital/sinus/brain radiologic examination and found responsible lesions in sphenoid sinus. All patients underwent endoscopic sinus surgery, and 9 patients were found to suffer sphenoid mucocele, 9 with fungal sinusitis, and 5 with sphenoid sinusitis. Visual disturbances improved in 6 patients, and all the patients with diplopia had a postoperative recovery. Visual disturbances resulting from ISSIDs are relatively uncommon, but it is crucial that the patient with new vision loss or diplopia and persistent headache or orbit pain be evaluated for the possibility of ISSIDs especially before corticosteroid administration.

    Variations of the dural venous sinuses may result in inaccurate imaging interpretation or complications during surgical approaches. One variation of the dural venous sinuses reported infrequently in the literature is the occipital sinus. We report an exceptional case of occipital sinus thrombosis. A 48-year-old right-handed man with a 5-month history of hypertension and chronic renal failure presented with cephalalgia, vomiting, and blurred vision evolving over 48 hours. Neurological examination revealed papillary edema stage 1 with no others abnormalities. An initial brain computed tomography (CT) scan performed was normal. The opening pressure of cerebrospinal fluid (CSF) was 35 cmH2O with normal level of protein and no hypercellularity in CSF analysis. The evolution was marked by the occurrence of generalized tonic-clonic seizure. A second CT scan performed showed a hyperdensity of the occipital sinus. Magnetic resonance imaging and magnetic resonance venography studies confirmed the diagnosis with highlighting the thrombosis of the occipital sinus in association to an ectasia of the torcular. The patient received adequate anticoagulation for 6 months in association to antiepileptic drugs with a good evolution. According to our review, such a thrombosis must be a rare condition, because our literature search has shown a lack of any report describing this condition. Herein, we review the anatomy of the occipital sinus and we illustrate the characteristics of this unusual thrombosis with multiple imaging modalities. Understanding of the cerebral venous anatomy and recognition of venous variations essentially help when dealing with a pathology, which presents along with a particular venous variation, no matter how rare this combination is.

    The International Frontal Sinus Anatomy Classification (IFAC) was introduced to more accurately characterize ethmoid and frontal sinus pneumatization patterns. The prevalence of IFAC cells and their anatomic associations have not been described. The goal was to examine the prevalence of IFAC cells and determine radiologic features associated with a low-lying anterior ethmoidal artery (LAEA). Imaging of adult patients who underwent computed tomographies from January 2015 to March 2016 were retrospectively reviewed by using the IFAC classification. We also measured the distance from the skull base to the anterior ethmoidal artery (AEA), the height of the lateral lamella of the cribriform plate, and anterior-posterior diameter from the anterior wall of the frontal sinus to the skull base (APF). Patients with a history of sinus surgery, trauma, malignancy, or congenital anomaly were excluded. Statistical analysis was performed by using Pearson correlation coefficients and χ2 tests. A total of 95 patients met the inclusion criteria. There was a significant association between supraorbital ethmoid cells and an LAEA (p < 0.001), with a significant effect size (φ = 0.276, p = 0.007). An inverse relationship was observed between Keros type I classification I and an LAEA (p < 0.001), with a significant effect size (φ = -0.414, p = 0.000). Significant associations were found between the AEA distance from the skull base and the cribriform lateral lamella height (R = 0.576, p < 0.001). In addition, there was a significant association between the AEA distance from the skull base and the APF (R = 0.497, p < 0.001). The presence of a supraorbital ethmoid cell and a wide APF were associated with an LAEA. There was a significant relationship between Keros type I classification and the AEA adjacent to the skull base. Delineation of these anatomic relationships may be helpful during endoscopic sinus surgery to avoid complications.

    Full Text Available Aim Implant rehabilitation has become a very reliable and safe procedure. However, in some cases, a small amount of bone could make implant surgery extremely difficult or even impossible. Hence, a surgical technique to augment sinus floor has been developed and improved. Nevertheless, there is still controversy over the use of a membrane over the osteotomy window. Therefore, the aim of this study was to investigate whether the use of a membrane could be beneficial in sinus floor augmentation. Materials and methods A group of 12 patients requiring sinus floor lift were recruited. The patients were randomly allocated to either control group (membrane or test group (no membrane and only one sinus for patient was augmented. After 6 months, a bone biopsy was harvested from the lateral window to be processed for histological analysis. Results The mean amount of newly formed bone in test group was 28.0±19.5%, the connective tissue accounted for a mean value of 59.2±15.6%, while 12.8±12.6% was the amount of residual graft particles. In the membrane group the newly formed bone counted for a mean value of 30.4±15.8%, the mean quantity of connective tissue was 50.3±18.9% and about residual graft particles a mean value of 18.2±20.4% was registered. Conclusion According to our data, the use of a membrane over the lateral bone wall in sinus lift surgery does not significantly influence healing. However, the membrane could influence the residual particles resorption rate as well as soft tissue ingrowth.

    The purpose of this study was to determine the prevalence of sinus opacification among dental paediatric patients. Two hundred and eight Cone Beam Computed Tomography (CBCT) scans of dental patients under the age of 18 were reviewed for sinus opacification. Patients with any sinus-related signs or symptoms were excluded. The overall prevalence of sinus opacification was 48.1%. The ethmoid (28.4%) and maxillary (27.8%) sinuses were most frequently affected. There were no statistically significant differences for both age and gender. The high prevalence of sinus opacification in asymptomatic children emphasizes the necessity of clinical correlation.

  8. Fibrous dysplasia and ossifying fibroma of the paranasal sinuses.

    1998-10-01

    Fibro-osseous lesions involving the paranasal sinuses, the mid-face and anterior skull base are uncommon. In addition, there appears to be no clear pathological or clinical classification that embraces the variety of lesions that exhibit such diverse pathological and clinical behaviour, yet may still be referred to as a fibro-osseous lesion. The diagnosis of fibrous dysplasia and ossifying fibroma is made on a combination of clinical, radiological and pathological criteria. This paper emphasizes the clinical and pathological differences between fibrous dysplasia and ossifying fibroma. The more aggressive clinical behaviour of the latter is highlighted and a more radical surgical approach is recommended. In contradistinction, fibrous dysplasia can exhibit a more benign behaviour and radical surgery is not always justified. A clinicopathological distinction between these two conditions is important from a management perspective despite the fact that they both may be encompassed under the 'umbrella' term fibro-osseous lesion.

    The radiological interpretation of postoperative changes of the paranasal sinuses requires knowledge of why and how the surgical intervention was performed and what the basic clinical findings were. It is important to know whether there was an inflammation, a reconstructive procedure, or a tumorous process. Multidetector computed tomography (MDCT) evaluated in a high-resolution bone window level setting represents the method of choice for imaging after nonfunctional and functional procedures after inflammatory changes as well as for imaging after reconstructive surgery because of facial trauma or before dental implantation. In the postoperative follow-up of tumor patients contrast-enhanced MDCT evaluated in a soft tissue window and bone window and especially magnetic resonance imaging (MRI) represent the standard. In many cases it is possible to differentiate tumor recurrence from inflammation with the help of contrast-enhanced multiplanar MRI and to detect bone marrow changes prior to CT. (orig.)

    2011-01-01

    Full Text Available Ondansetron is a serotonin receptor antagonist which has been used frequently to reduce the incidence of post-operative nausea and vomiting in laparoscopic surgery. It has become very popular drug for the prevention of post-operative nausea and vomiting due to its superiority in-terms of efficacy as well as lack of side effects and drug interactions. Although cardiovascular adverse effects of this drug are rare, we found a case of symptomatic sinus bradycardia in a 43-year-old female patient, going for laparoscopic cholecystectomy, who developed the same after she was given intravenous ondansetron in operation theater during premedication. Hence, we report this case, as the rare possibility of encountering bradycardia effect after intravenous administration of ondansetron should be born in mind.

    Tumors of the nose and paranasal sinuses are diverse. Successful treatment depends on accurate delineation of tumor extent via careful physical examination and roentgenographic workup. Treatment selection is based on these findings as well as on the general condition and age of the patient and tumor histology. Surgery, irradiation, and combined therapy all have a role and are selected to produce the best cure rate with an acceptable functional and cosmetic result. These tumors occur in proximity to a number of vital structures, and a variety of severe complications can occur secondary to treatment. While these complications cannot be entirely avoided, they are best kept to a minimum by careful treatment planning and cooperation among the otolaryngologist, radiation therapist, and ophthalmologist

    To analyze the clinical patterns, etiologies, treatment, and outcome of cerebral venous sinus thrombosis (CVST) in 2 major cities of Saudi Arabia, Jeddah and Al-Baha. One hundred and eleven patients diagnosed as CVST were identified from the medical records at King Abdulaziz Medical City, Jeddah, and King Fahad Hospital, Al-Baha, Saudi Arabia, from January 1990 through November 2010. We retrospectively analyzed the data, compared it with local and international studies, and reviewed the literature. There were 92 adults and 19 children. Among adults, females predominated, while more boys were affected than girls. The mean age of onset was 29.5 years. The most common clinical presentations were headache, focal neurologic deficits, seizures, papilledema, and decreased level of consciousness. The main risk factors identified were pregnancy/ puerperium, antiphospholipid antibody syndrome, oral contraceptive pills, malignancy, and infections. Multiple sinuses were affected in 51 patients (45.9%). When a single sinus was involved, the superior sagittal sinus (24.3%) was the most common. Seventy-four patients recovered completely, 23 patients recovered partially, and 10 patients died. Bad prognostic factors included incurable co-morbid conditions, late presentation, and status epilepticus. Pregnancy/puerperium was the most common etiological factor in our series. Clinical features were similar to international series. Behcet`s disease was not a major etiological factor in our series. Most patients had involvement of multiple sinuses. Prompt treatment with anticoagulation resulted in complete or partial recovery in 87.4% of patients.

    Diseases of nose and paranasal sinuses can complicate to involve the orbit and other surrounding structures because of their close proximity. These diseases are usually infective or can be neoplastic in origin. Method: All the patients presenting in ENT or Eye Departments of Ayub Teaching Hospital during the one year study period who had complicated nose or paranasal sinus disease were included in the study. A detailed history and examination followed by CT scanning and laboratory investigations to assess the type and extent of the disease, was carried out. Results: Infections were the most common cause of complicated sinus disease 11 (75%). The rest of the 4 (25%) cases were tumours. 12 (80%) of the cases presented with proptosis. In 1 of these 12 cases, there was complete blindness. In 2 (13%) of the cases there was only orbital cellulitis. Two of these patients had facial swelling and 2 had nasal obstruction and presented as snoring. Two patients presented with history of weight loss and these patients had malignant tumour of the paranasal sinuses. One patient presented with early signs of meningitis. In 1 case sub periosteal scalp abscess (Pott's puffy tumour) was the only complication noted. Conclusion: Nose and paranasal sinus diseases can complicate to involve mostly the orbit, but sometimes brain, meninges and skull bones can also get involved. (author)

    2015-01-01

    Sinus node disease and atrioventricularis disorders are very rarely observed in women during pregnancy. Bradyarrhythmia in pregnant women is divided into mild bradycardia connected with pressure on venous cava inferior by growing fetus, new detected AV disorders and existing before pregnancy: AV Ill degree block congenital or after surgery, sinus node disease and channelopathies. Management in bradyarrhythmia in pregnancy is very difficult, despite guidelines. Whenever possible problem should be resolved before pregnancy. When symptomatic AV III degree block with wide QRS complex escape rhythm is observed--the permanent pacing should be considered with echocardiography or electro-anatomical system using. Another option is novel temporary, prolonged pacing.

    2007-07-01

    Full Text Available Background and Aim: Accurate measurement of bone height and width is essential prior to dental implant placement. The method of surgery as well as, the type and size of implants are determined according to dimensions of the residual bone. The purpose of this study was to evaluate the accuracy of linear tomography in localization of the floor of nasal fossa and maxillary sinus, and to determine the width of maxillary bone at the designated site for implant placement.Materials and Methods: In this test evaluation study, the vertical distances between the alveolar crest and the floor of nasal fossa and the floor of maxillary sinus was measured by the tomographic slices in 12 sites of three dry human skulls. In addition, the width of maxillary bone was measured at the same slices. The skulls were then sectioned through the marked places. Then the radiographic values were compared with the real values of bone sections.Results: After correction of tomographic values by the magnification factor of the unit, the mean absolute measurement error for vertical values at nasal fossa and maxillary sinus area in tomographic slices were 0.28 mm (SD= 0.24 and 1.1 mm (SD= 0.68 respectively. The mean absolute measurement error for maxillary width at the nasal fossa and maxillary sinus area were 0.65 mm (SD= 0.50 and 0.55 mm (SD= 0.45 respectively. 100 % of vertical values at nasal fossa area and 50 % of vertical values at maxillary sinus area were within ± 1 mm error limit. In addition, 50 % of width measurements at nasal fossa area and 83.3 % at maxillary sinus area were within ± 1 mm error limit.Conclusion: The linear tomography is more accurate in height estimation at nasal fossa area and in width estimation at maxillary sinus area. The accuracy of linear tomography in height and width estimation is within acceptable limits at both nasal fossa and maxillary sinus area.

    The aim of this study was to retrospectively evaluate the surgical technique of sinus floor elevation with autogenous parietal bone grafting in conjunction with immediate dental implants for the reconstruction of the maxilla in deficient maxillary alveolar ridges. Seventeen patients who underwent sinus floor elevation with bone graft from the parietal bone between 2005 and 2007 were included in the study. Cases of extremely deficient bone level in the alveolar ridgeAnkylos®) with different length and diameter were placed immediately after the graft was placed. Strict oral hygiene was required for the patients. Presurgical and postsurgical panoramic radiographs were taken. A high-quality reconstruction with an increase in lifted sinus bone height was achieved with parietal bone particulates. Seventy-three implants were clinically osseointegrated and four implants were lost giving a success rate 94.8%. No correlation was found between failure and the surgery. The encouraging results of this study suggest that the technique of reconstruction of the sinus floor and the resorbed alveolar ridge using an autogenous parietal bone graft is reliable, giving the surgeon the opportunity to successfully perform immediate implant placement in more difficult and deficient maxillary alveolar bone height.

    The fungus ball is the most frequent type of fungal rhino-sinusitis. The objective of this study is to analyze the clinical and surgical features of our patients. Retrospective analysis of 35 patients with fungus ball treated in our centre between 2006 and 2014. Mean age was 55 years old. 49% were men and 51% women. 75% involved the maxillary sinus, whereas 25% involved the sphenoid. 69% of our patients showed microcalcifications in the CT study. All the patients were surgically treated, with no cases of recurrence. Clinical manifestations of fungus ball are non-specific, therefore endoscopy and image study are mandatory. The definitive diagnosis is made by histopathological study of the lesion. Endoscopic sinus surgery is the treatment of choice, with opening of the diseased sinus and complete removal of the fungus ball. The frequency of complications is very low. No oral or topical antimycotic treatments are necessary. Copyright © 2015 Elsevier España, S.L.U. and Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello. All rights reserved.

    2009-10-01

    The aim of this preliminary study was to evaluate histologically a nanocrystalline hydroxyapatite silica gel in maxillary sinus floor grafting in severely resorbed maxillae. A total of 16 consecutive patients scheduled for sinus lift were recruited during this study. Patients were randomly divided in two groups, eight patients each. In both groups, preoperative residual bone level ranged between 1 and 3 mm (mean value of 2.03 mm). No membrane was used to occlude the buccal window. Second surgery was carried out after a healing period of 3 months in Group 1 and 6 months in Group 2. Using a trephine bur, one bone specimen was harvested from each augmented sinus and underwent histological and histomorphometric analysis. Histological analysis showed significant new bone formation and remodeling of the grafted material. In the cores obtained at 6 months, regenerated bone, residual NanoBone, and bone marrow occupied respectively 48 +/- 4.63%, 28 +/- 5.33%, and 24 +/- 7.23% of the grafted volume. In the specimens taken 3 months after grafting, mean new bone was 8 +/- 3.34%, mean NanoBone was 45 +/- 5.10%, and mean bone marrow was 47 +/- 6.81% of the bioptical volume. Within the limits of this preliminary prospective study, it was concluded that grafting of maxillary sinus using nanostructured hydroxyapatite silica gel as only bone filler is a reliable procedure also in critical anatomic conditions and after early healing period.

    Full Text Available Introduction: Paranasal sinus plays an important role in the formation of facial contours. Therefore, knowledge of the development and size of the maxillary sinus and frontal sinus may be crucial for diagnosing and treating various classes of malocclusion. Aim: To evaluate the reliability of frontal sinus with that of maxillary sinus in the assessment of different types of skeletal malocclusions. Settings and Design: Sample consisted of lateral cephalograms of 240 patients with three different skeletal malocclusions. Material and Methods: The sample for the study consists of 240 patients (120 males and 120 females with age of the subjects ranging from 16 to 25 years divided into skeletal Class I, II, and III on the basis of ANB angle (each 40 patients. Linear and angular cephalometric measurements were assessed and correlate with maxillary and frontal sinus size, which is obtained through AutoCAD program. Statistical Analysis: Pearson′s correlation coefficient used. Results: The results show a significant correlation of frontal sinus with skeletal malocclusion (P < 0.05 as compared to the maxillary sinus. Conclusions: (1 Frontal sinus is more reliable as compared to maxillary sinus in depicting skeletal malocclusion. (2 Frontal sinus area larger in skeletal Class III malocclusion as compared to skeletal Class I and Class II malocclusion. (3 There is no significant variation in maxillary sinus area in males and females whereas frontal sinus shows significant variations in both males and females in different skeletal malocclusions.

    Full Text Available Dysautonomia in Guillain-Barre syndrome (GBS rarely causes serious cardiovascular complications, such as sinus arrest. Miller Fisher syndrome (MFS is recognized as a variant of GBS. There have been few reports regarding the association between MFS and dysautonomia. We describe a case of a 68-year-old man with ophthalmoplegia, bulbar palsy, truncal ataxia, and areflexia. He was diagnosed with MFS because he exhibited the classical clinical triad and had elevated serum anti- GQ1b immunoglobulin G levels. A magnetic resonance imaging scan of his head was normal. His 24-hour Holter recording showed sinus arrest. He was treated with intravenous immunoglobulin, whereupon his symptoms gradually improved. This included the sinus arrest, which was considered a symptom of dysautonomia in MFS. Therefore, clinicians should be mindful of dysautonomia not only in GBS patients, but also in cases of MFS.

    As anorexia patients always go to the psychiatric clinic, little is concerned about the occurrence of sinus bradycardia in these patients for cardiologists and psychiatrists. The aim of this paper is to discuss the relationship between anorexia and sinus bradycardia, and the feature analysis, differential diagnosis and therapeutic principles of this type of sinus bradycardia. We report a case of sinus bradycardia in an anorexia patient with the clinical manifestations, laboratory exams, auxiliary exams, therapeutic methods, and her prognosis, who was admitted to Peking University Third Hospital recently. The patient was a 19-year-old female, who had the manifestation of anorexia. She lost obvious weight in a short time (about 15 kg in 6 months), and her body mass index was 14.8 kg/m(2). The patient felt apparent palpitation, chest depression and short breath, without dizziness, amaurosis or unconsciousness. Vitals on presentation were notable for hypotension, and bradycardia. The initial exam was significant for emaciation, but without lethargy or lower extremity edema. The electrocardiogram showed sinus bradycardia with her heart rate being 32 beats per minute. The laboratory work -up revealed her normal blood routine, electrolytes and liver function. But in her thyroid function test, the free thyroid (FT) hormones 3 was 0.91 ng/L (2.3-4.2 ng/L),and FT4 was 8.2 ng/L (8.9-18.0 ng/L), which were all lower; yet the thyroid stimulating hormone (TSH) was normal 1.48 IU/mL (0.55-4.78 IU/mL). Ultrasound revealed her normal thyroid. Anorexia is an eating disorder characterized by extremely low body weight, fear of gaining weight or distorted perception of body image, and amenorrhea. Anorexia patients who lose weight apparently in short time enhance the excitability of the parasympathetic nerve, and inhibit the sympathetic nerve which lead to the appearance of sinus bradycardia, and functional abnormalities of multiple systems such as hypothyroidism. But this kind of sinus

    Treatment of dural arteriovenous fistula involving the transverse-sigmoid region with cortical reflux is complex and treatment options may require sacrifice of the fistulous segment of the sinus. To review our results in this subset of patients and describe current endovascular decision-making and approaches. We reviewed cases of endovascular sinus sacrifice for dural fistulas at our institution from 2007 to 2012. Demographic, decision-making, technical and outcome data were collected. Seven patients were identified who underwent endovascular sinus sacrifice for treatment of dural fistula during this 4-year period. Determination of the fistulous sinus segment was based on the pattern of cortical drainage. Endovascular access to the sinus was achieved by transarterial, transvenous or via open surgery in one case. Complete cure of the target fistula was obtained in all cases. One patient had transient post-procedure headache. There were no hemorrhages, new neurological deficits or signs of increased intracranial pressure. Six of the seven patients had angiographic follow-up at least 6 months after treatment with no recurrence. Fistulas of the transverse-sigmoid sinuses with cortical reflux may require sacrifice of the parent sinus for cure. Defining the fistulous segment and occluding this segment deliberately, completely and precisely is essential for cure. Several modalities and approaches can be used to achieve this. For properly selected patients, cure of the lesions can be achieved with this method with low risk of morbidity.

In previous studies, it has been shown that silk fibroin–nano silver solution can eliminate S. aureus biofilms in vitro, which suggests a potential role of this novel agent in the treatment of biofilm-associated diseases, such as sinusitis.Objective: The aim of this study was to investigate the efficacy of silk fibroin–nano silver solution as a topical anti-biofilm agent in a rabbit model of sinusitis.Methods: Biofilm-associated sinusitis models were established in 24 New Zealand White rabbits by gelatin sponge placement and S. aureus inoculation through a hole drilled into the anterolateral wall of the right maxillary sinus. After 4 weeks, indwelling catheters were placed into the maxillary sinus. Different concentrations of silk fibroin–nano silver solution or normal saline were irrigated slowly into the maxillary sinus via the indwelling catheters. After 7 days of irrigation, the rabbits were sacrificed. The sinus mucosa was harvested and examined for biofilm biomass as well as morphological integrity of the epithelium by scanning electron microscopy.Results: Silk fibroin–nano silver solution was found to be most effective in reducing the biomass of the S. aureus biofilms at a concentration of 384 mg/L, followed by the concentration of 153.6 mg/L, when compared with saline. After treatment with 384 mg/L silk fibroin–nano silver solution, the biofilms were completely

    To investigate antibiotic sensitivities of Streptococcus pneumoniae, viridans streptococci, and group A hemolytic streptococci isolated from the culture materials obtained from the sinuses of patients undergoing functional endoscopic sinus surgery due to chronic sinusitis. We recruited 93 patients (63 males, 30 females; mean age 36+/-17.5; range 19 to 68 years) who underwent functional endoscopic sinus surgery due to chronic sinusitis. Before surgical intervention, in order to eliminate a possible contamination from the skin and neighboring structures, nasal mucosa was cleansed with povidone-iodine solution. Nasal smear samples were obtained from all the patients before and after applying povidone-iodine solution. Streptococcus pneumoniae, viridans streptococci and group A hemolytic streptococci that were isolated from the cultures were tested for antibiotic sensitivity. The number of anaerobic bacteria isolated from 58 patients (62.3%) before applying povidone-iodine was 72, following the application of povidone-iodine a total of 16 microorganisms were identified from 12 patients (12.9%). Microorganisms were isolated from 95.6% (89/93) of the samples obtained from the maxillary sinuses and 91.3% (85/93) of the samples obtained from the ethmoid sinuses. The most commonly identified microorganisms from both sinuses were coagulase negative staphylococcus followed by viridans streptococci, coagulase positive staphylococcus, Streptococcus pneumoniae and group A hemolytic streptococci. For viridans streptococcal strains that were isolated, 33.3% were resistant to tetracycline, 23.8% to chloramphenicol, and 19.04% to penicillin. Hemolytic streptococci strains were sensitive to penicillin, ofloxacin, ceftriaxone, and cefepime in all the groups; however, they had 50% resistance to erythromycin and chloramphenicol and 100% resistance to tetracycline. The resistance pattern of the isolated Streptococcus pneumoniae strains were as follows: 25% to penicillin, 66.6% to

    Posterior fossa dural venous sinus thrombus is a well-described complication of head trauma, especially when fracture crosses the dural sinus grooves or in association with epidural hemorrhage. We have found that post-traumatic posterior fossa epidural hematoma compressing a dural venous sinus can mimic dural venous thrombus. To discuss the CT and MRI findings of posterior fossa epidural hemorrhages simulating sinus thrombosis, to make radiologists aware of this important imaging pitfall. We describe radiologic findings in four children in whom a posterior fossa epidural hemorrhage mimicked dural venous sinus thrombus. Routine CT head and CT venography were obtained on Toshiba volume and helical CT scanners. MRI and MR venography were performed on a Philips scanner. In all cases there was medial displacement and compression of the posterior fossa dural venous sinuses without intraluminal thrombosis. The epidural hemorrhage was seen tracking along sinus grooves in the occipital bone, peeling the dura containing the sinuses from the calvarium and compressing the sinus, simulating thrombosis on axial CT views. Both venous sinus thrombosis and posterior fossa epidural hemorrhages in children are well-described complications of head trauma. Posterior fossa epidural hemorrhage can mimic a sinus thrombus by compressing and displacing the sinuses. It is important to recognize this pitfall because treatment of a suspected thrombus with anticoagulation can worsen epidural hemorrhage. (orig.)

    Since an accurate description on the pathophysiology of the nasal cavity and paranasal sinus (PNS) was established, a detailed evaluation of their anatomic and pathologic status, especially of the ostiomeatal unit, has become important, and computed tomography (CT) has increasingly been used for evaluating chronic sinusitis. This study was undertaken to assess the value of CT in chronic or recurrent paranasal sinusitis and to ascertain the theory of rhinogenic origin as the pathophysiologic basis of sinusitis. We retrospectively analyzed the PNS CT findings of 108 patients with chronic or recurrent sinusitis. The CT scan were obtained in thin-section (3mm or 5mm) coronal and axial planes after contrast medium administration. With respect to the location of the sinusitis, the anterior ethmoid sinus was involved in 98 (91%), maxillary sinus in 93 (86%), frontal sinus in 60 (56%), posterior ethmoid sinus in 35 (32%), and sphenoid sinus in 32 cases (30%). CT finding of the sinusitis consisted of sinus opacification (74%), mucoperiosteal thickening (69%), mucosal enhancement (36%), air-fluid level (18%), and bony wall thickening (11%). Complications included retention cysts (29%), mucoceles (8%), and orbital cellulitis (1%). Obstruction of the ostiomeatal unit was noted in 104 cases (96%), which were composed of inflammatory process, nasal polyps, concha bullosae, inverting papillomas, paradoxic middle turbinates, severe septal deviations, and large ethmoidal bulla. Of the 17 cases with a past history of Caldwell-Luc operation, 15 cases showed obstruction of the ostiomeatal units. We concluded the CT was a very useful modality for evaluating chronic or recurrent sinusitis and for demonstrating the finely detailed pathologic anatomy of the nasal cavity and paranasal sinuses.

    272 patients with tumours of the nasal cavity and paranasal sinuses were followed up from 1949 until 1982. 53% of the tumours were classified as squamous cell or undifferentiated carcinomata. The most common site of squamous cell carcinoma is the maxillary sinus (50%). Distant metastases and regional lymph node metastases are rarely seen at presentation regardless of the size of the primary tumour. Metastases usually indicate a tumour dependent death in the near future. The main prognostic indicators are the size of the tumour (significantly worse prognosis for T4 in comparison to T2 or T3 tumours) and the localisation (significantly better prognosis for tumours of the floor of the nasal cavity or the nasal septum compared to tumours of the paranasal sinuses). The age of the patient or the degree of differentiation of the tumour did not influence on the survival rate. Tumour dependent deaths rarely occur after more than five years. Patients were assigned to two treatment groups and matched according to the tumour stage. One group received surgery only, whereas the second group received a combined treatment of surgery with subsequent radiotherapy. There was a significant difference between the two groups in favour of the surgical treatment. According to these data we recommend surgical excision without postoperative irradiation in cases where complete removal of the tumor has been histologically proven. (orig./MG) [de

    Objective: To study the imaging features of meningiomas of ethmoid sinuses. Methods: Six cases of meningiomas of ethmoid sinuses verified pathologically were analyzed retrospectively. Results: CT scans of 6 cases exhibited huge cystic masses (n = 3), huge cystic-solid masses (n = 2), huge solid mass (n = 1). The cystic walls were remarkable osteosclerosis. The density of solid masses were homogeneous, or heterogeneous with calcifications and cystic changes, and prominent contrast-enhancement. MR images of 1 case (1/6) showed a cystic-solid mass, the cystic portion was high signal intensity on T 2 WI and low signal intensity on T 1 WI, while the solid mass was iso-signal intensity on T 1 WI and T 2 WI. The solid portion was enhanced. X-ray plain films of 3 cases (3/6) displayed ethmoid sinuses enlargement and high density. Conclusion: For the meningiomas of ethmoid sinuses, CT finding was specific, MRI was helpful in differential diagnosis, and X-ray plain films was of no qualitative value

    Full Text Available Background: Metronomic chemotherapy consisting of methotrexate and celecoxib recently has shown promising results in multiple studies in head and neck cancers. However, these studies have not included patients with maxillary sinus primaries. Hence, the role of palliative metronomic chemotherapy in patients with maxillary sinus carcinoma that is not amenable to radical therapy is unknown. Methods: This was a retrospective analysis of carcinoma maxillary sinus patients who received palliative metronomic chemotherapy between August 2011 and August 2014. The demographic details, symptomatology, previous treatment details, indication for palliative chemotherapy, response to therapy, and overall survival (OS details were extracted. SPSS version 16 was used for analysis. Descriptive statistics have been performed. Survival analysis was done by Kaplan-Meier method. Results: Five patients had received metronomic chemotherapy. The median age was 60 years (range 37-64 years. The proportion of patients surviving at 6 months, 12 months, and 18 months were 40%, 40%, and 20%, respectively. The estimated median OS was 126 days (95% confidence interval 0-299.9 days. The estimated median survival in patients with an event-free period after the last therapy of <6 months was 45 days, whereas it was 409 days in patients with an event-free period postlast therapy above 6 months (P = 0.063. Conclusion: Metronomic chemotherapy in carcinoma maxillary sinus holds promise. It has activity similar to that seen in head and neck cancers and needs to be evaluated further in a larger cohort of patients.

    Complications after cardiac surgery are common and lead to substantial increases in morbidity and mortality. Meta-analyses of small randomized trials have suggested that perioperative statin therapy can prevent some of these complications. We randomly assigned 1922 patients in sinus rhythm who were scheduled for elective cardiac surgery to receive perioperative rosuvastatin (at a dose of 20 mg daily) or placebo. The primary outcomes were postoperative atrial fibrillation within 5 days after surgery, as assessed by Holter electrocardiographic monitoring, and myocardial injury within 120 hours after surgery, as assessed by serial measurements of the cardiac troponin I concentration. Secondary outcomes included major in-hospital adverse events, duration of stay in the hospital and intensive care unit, left ventricular and renal function, and blood biomarkers. The concentrations of low-density lipoprotein cholesterol and C-reactive protein after surgery were lower in patients assigned to rosuvastatin than in those assigned to placebo (PSTICS ClinicalTrials.gov number, NCT01573143.).

    Dermal sinus tracts are remnants of incomplete neural tube closure. Dermal sinus tracts in the spine range from asymptomatic pits to tracts with significant disease. Congenital spinal dermal sinus tract can produce significant morbidity if not adequately managed. Spinal subdural abscess caused by the spread of an infection within the dermal sinus tract is rare in children. We now described a 3-year-old male who presented with extensive spinal subdural abscess resulting from dermal sinus tract that was low-lying in the sacral area.

    To study the point prevalence of allergic rhinitis and sinusitis in childhood asthma and to examine the relationship among them. In 250 children (age allergic rhinitis was diagnosed by clinical plus nasal eosinophilia criteria, and sinusitis was diagnosed clinically plus confirmation by computerized tomography scan. The point prevalence of allergic rhinitis was 13.6%, and of sinusitis was 2%. On multivariate analysis, allergic rhinitis, sinusitis, and family history were significantly associated with asthma severity. Allergic rhinitis is common in childhood asthama, but sinusitis is rare.

    The author have observed mucoid retention cyst in the right maxillary sinus of the patient, 41 year old woman, complained discharging of purulent exudate on the right maxillary molar area, and obtained the following conclusions; 1. The mucoid retention cyst in maxillary sinus casts a faint dome shaped shadow into the radiolucent image of maxillary sinus. 2. The mucoid retention cyst in maxillary sinus may occurred without the history of trauma. 3. Intraoral standard films are also valuable for the interpretation of the lesions in maxillary sinus but only extraoral roentgenograms.

    Full Text Available Syncope is a sudden and brief loss of consciousness with postural tone. Its recovery is usually spontaneous. There are various causes of syncope including cardiac, vascular, neurologic, metabolic and miscellaneous origins. The tracing is usually time-consuming and costly. The diagnosis of carotid sinus syncope may sometimes be difficult since the symptoms are nonspecific, especially in older persons. Here, we report the case of a 72-year-old woman who sought medical attention at our hospital due to repeated syncope episodes over the previous 5 years. Neurologic examinations showed negative results (including brain computed tomography. Twenty-four-hour ambulatory electrocardiogram monitoring showed atrial and ventricular premature contractions only. Electrophysiologic study disclosed prolonged corrected sinus node recovery time (1,737 ms with poor atrioventricular conduction. Drop of blood pressure together with sinus bradycardia developed after left side carotid sinus massage. Both carotid sinus hypersensitivity with sick sinus syndrome contributed to this patient's syncope, and after pacemaker placement together with selective serotonin reuptake inhibitor treatment, she was free from syncope thereafter.

    Fibro-osseous lesions of the paranasal sinuses are an uncommon heterogeneous group of lesions with variable clinical presentation. It is unclear whether these lesions directly cause symptoms or secondarily obstruct the sinuses with resultant rhinosinusitis. We have used an expectant management approach in selected patients that includes observation with serial scans or endoscopic sinus surgery (ESS) to improve the outflow tract of the affected sinus without resection of the lesion. The purpose of this work is to review our experience with management of paranasal sinus fibro-osseous lesions. Retrospective chart review from 1997 to 2009. A total of 44 patients were identified in this study. There were 19 (43%) osteoma and 25 (57%) fibrous dysplasia cases. The presenting symptoms were mainly sinonasal with headaches (36%), pain/pressure (19%), and nasal obstruction (17%). Two patients (4.5%) presented with proptosis and diplopia. Five (11%) patients had associated nasal polyps. The diagnosis was an incidental finding in seventeen (38%) cases. Twenty-two (50%) patients were managed conservatively with serial computed tomography (CT) scans to monitor for interval growth over a mean interval of 41.8 months (range, 13-130 months). There were 2 patients in the observation group with CT scan evidence of interval growth with an increase in size of 1 mm and 9 mm over 130 and 36 months, respectively. Twelve symptomatic patients (27%) underwent ESS without resection of the lesion, with symptomatic improvement in 11 patients (92%). Four patients (9%) underwent endoscopic biopsy to attain histological diagnosis. Six (13%) patients in this study had resection of their lesion with 5 of the patients having symptomatic improvement following resection. In patients with fibro-osseous lesions, we support an expectant management approach of asymptomatic patients with observation and serial imaging, treating selected symptomatic patients with ESS and resection of the lesion in patients

    Objective: To explore the features of inflammatory pseudotumor in the maxillary sinus on CT and MRI. Methods: The CT and MRI data of 8 patients with histology-proven inflammatory pseudotumor in the maxillary sinus were retrospectively analyzed. All 8 patients underwent CT scans and 7 of them also underwent MRI examinations. In addition, the time-intensity curve (TIC) of dynamic contrast-enhanced (DCE)MR imaging were analyzed in 3 patients. Results: Two cases had lesions in the left maxillary sinus, while the others showed lesions in the right maxillary sinus. All the lesions showed irregular shape with well-defined margins in 5 cases and hazy margins in 3 cases. The mean maximum diameter of the lesions was 51 mm (ranged from 29 mm to 72 mm). On non-enhanced CT, the lesions were isodense to gray matter in 6 and slightly hypodense in 2 patients. Only 2 patients had post-contrast CT with moderate enhancement of their lesions. The lesions caused adjacent bony absorption and destruction with residual bony sclerosis. On MR T 1 WI, inflammatory pseudotumor showed hypointense in 2 patients and isointense in and isointense in 1 patients. Inflammatory pseudotumor showed heterogeneously slight contrast enhancement in 2 cases and moderate enhancement in 5 cases. The TIC showed a steady enhancement pattern in 4, orbit in 4, and cheek in 3 cases. Six patients underwent follow-up for 2-5 years after surgery and 2 of them were found to have recurrence. In comparison to CT, MRI was proved to show the extent of the lesions more clearly. Conclusions Bony destruction with sclerosis and hypointense signal on MR T 2 WI are typical manifestations of inflammatory pseudotumor in the maxillary sinus. Combined CT and MRI can provide clinicians with more comprehensive information for the diagnosis, therapy, and follow-up of these lesions. (authors)

    Full Text Available Introduction: Fungal ball of the sinuses is a not invasive infection that if characterizes for its chronicity, being the majority related with previous endodontic treatment. Affect mainly the breasts to maxillary; even so all the breasts can be involved. The main etiological agent is the Aspergillus spp. The computed tomography, had to characteristic the radiological presentations, suggests the diagnosis that is carried through definitively through histopathological analyses. The treatment standard-gold is the sinus surgery with average meatal antrostomy. Objective: Reporting two cases of fungal ball of the sinuses and to stand out important aspects of this pathology. Story of the Cases: Case 1 Patient of the feminine sex, 78 years old, presented itself with complaints of face pain has 6 months and previous history of endodontic treatment. To the physical examination it was evidenced purulent secretion presence in left average meatus. Ray X presented complete veiling of the breasts to maxillary left, while the computed tomography showed injury calcified in this place. Sinusotomy was become fulfilled that evolved well. Case 2 Patient of the feminine sex, 70 years old, looked attendance for history of sinusitis of repetition. To the physical examination no particularity was not perceived. The computed tomography, as well as the magnetic resonance, detected thickening of the mucous wall of the breasts to maxillary left, beyond a calcified mass. It was become fulfilled same sequence of treatment and the patient also evolved well. Final Considerations: The fungal infection must be considered in the patients who if present with chronic sinusitis, that they do not answer to the antibiotic use and that they possess history of endodontic manipulation.

    Nasofrontal dermal sinuses are very rare and generally occur in children. This congenital malformation can be revealed by midface swelling, which can be complicated by local infection or neuromeningitis. Such complications make the dermal sinus a life-threatening disease. Two cases of nasofrontal dermal sinuses are reported in this work. The first case is an 11-month-old girl who presented with left orbitonasal soft tissue swelling accompanied by inflammation. Physical examination found fever, left orbitonasal thickening, and a puncture hole letting out pus. Computed tomography revealed microabscesses located at the left orbitonasal soft tissues, a frontal bone defect, and an intracranial cyst. Magnetic resonance imaging showed the transosseous tract between the glabella and the brain and affirmed the epidermoid nature of the intracranial cyst. The second case is a 7-year-old girl who presented with a nasofrontal non-progressive mass that intermittently secreted a yellow liquid through an external orifice located at the glabella. MRI revealed a cystic mass located in the deep layer of the glabellar skin related to an epidermoid cyst with a nasofrontal dermal sinus tract. In both cases, surgical excision was performed, and pathological confirmation was made for the diagnoses of dermal sinuses. The postoperative course was favorable. Through these cases, the authors stress the role of imaging methods in confirming the diagnosis and looking for associated cysts (dermoid and epidermoid) to improve recognition of this rare disease. Knowledge of the typical clinical presentations, imaging manifestations, and most common sites of occurrence of this malformation are needed to formulate a differential diagnosis.

    We attempted to investigate the role of nasal allergy in sinusitis to elucidate whether it results from an immediate-type allergic reaction of the sinus mucosa or from allergic edema-induced sinus ostial obstruction. Forty-two patients with chronic sinusitis were selected for allergen skin tests, measurements of serum total and specific IgE, and sinus tissue-specific IgE. The data were then correlated to examinations of nasal mucosal scrapings and histopathology of the sinus mucosa. We found that serum levels of total IgE and house dust mite-specific IgE antibodies were significantly higher in patients (n = 12) allergic to house dust than in the nonatopics (n = 30; p less than 0.0001). There was no difference in the sinus tissue-specific IgE antibody. Eosinophils and basophilic cells in epithelial scrapings from the inferior turbinates, assessed by Hansel staining, were high in 66.7% and 50% of the atopic patients, respectively, and 36.7% and 26.7% of the nonatopics, respectively. The rates were influenced by the existence of infection and nasal polyps. The increase in eosinophils, mast cells and plasma cells, assessed by histopathologic examination, were not prevalent in the sinus mucosa of atopic patients. It is concluded that nasal allergy may be a predisposing factor to sinusitis and that the pathologic change of the sinus mucosa is mainly secondary, due to sinus ostial obstruction.

    Malignant tumours of maxillary sinus are rare. They are usually diagnosed in the late stages when they perforate the sinus walls. The presence of large air space in the maxillary sinus facilitates asymptomatic growth of the sinus malignancy. The clinical presentation of these tumours depends on the sinus wall involved by the disease. The medial wall is usually the first to become eroded, leading to nasal obstruction, epistaxis or discharge. Rarely, symptoms of maxillary sinus carcinoma can resemble dental infection and the affected patients may visit dental clinic seeking treatment. This report presents a case of carcinoma of maxillary sinus mimicking odontogenic infection. Computed tomographic findings explained the reason for the present lesion to masquerade as an inflammatory condition. The importance of advanced imaging modalities for prompt identification of such lesions is discussed.

    We report an unusual case of a displaced maxillary molar and associated dentigerous cyst within the maxillary sinus in an adolescent presenting as recurrent sinusitis. Although a rare cause of sinusitis in children, dentigerous cysts should be included in the differential diagnosis for causes of persistent or recurrent sinusitis in this age group. This report provides further evidence for obtaining imaging studies when managing pediatric sinusitis that does not respond to standard antibiotic therapy. We discuss management options for these lesions including the differential diagnoses and need for follow-up. (orig.)

    Background. The sphenoid sinus is a frequent target of paranasal sinus surgery. Because of the high risk of injuring the surrounding structures (e.g. internal carotid artery, optical nerve) a preoperative imaging is absolutely necessary. Purpose. To analyze the possibilities of cone-beam computed tomography (CBCT), which is especially quite a new technique in ENT, in the evaluation of the sphenoid sinus, its surrounding structures, and the corresponding anatomical variations. Material and Methods. This was a retrospective, single-centre study of 580 patients (1160 sides = cases). The Accu-I-Tomo-F17 was used. Pneumatization of sphenoid sinus, course of internal artery, course of optical nerve, and dehiscence of the bony canals were evaluated. Results. In the case of pneumatization a type I (completely missing or minimal sphenoid sinus) was found in two patients (0.3%), type II (posterior wall of sphenoid sinus is in front of the anterior wall of the sella) in 38 patients (6.6%), type III (posterior wall is between anterior and posterior wall of sella) in 332 patients (57,2%), type IVa (posterior wall is behind the posterior wall of sella without air dorsal the sella) in 104 patients (17.9%), and type IVb (similar to type IVa but with air dorsal the sella) in 104 patients (17.9%). In 1025 cases (89.5%) a smooth course of the internal carotid artery was found whereas a free course could be detected in 120 cases (10.5%). Defects of the bony canal of the optical nerve were found in 16.7% and of the internal carotid artery in 2.7% of the cases. The optical nerve showed a free course through the sphenoid in 151 cases (13.7%) and a smooth course in 1007 cases (87.0%). Conclusion. CBCT could evaluate all relevant anatomic structures and answer the questions of different anatomical variants. A modified classification of the pneumatization of the sphenoid sinus could be described. Frequencies of anatomical variations are in accordance with the current literature of CT

    Purpose: To determine the value of MRI in the preoperative evaluation of chronic paranasal sinusitis and to compare the results with CT and intraoperative findings. Method/Materials: 42 patients with clinical signs of chronic paranasal sinusitis underwent MRI after CT evaluation on one day, with subsequent functional endoscopic sinus surgery on the next day. Coronary CT was obtained with 5-mm slices and table-feed in the prone position, while MRI was performed in the supine position with coronary T{sub 2}-TSE+pd and coronary and transverse HASTE, each with 5-mm slice thickness. Aquisition time in MRI was less than 8 minutes. Two radiologists reviewed the CT and MRI scans for signs of sinusitis and detection of anatomical landmarks. The results were correlated with the intraoperative findings. Results: MRI offered no artifacts of dental work and showed more often high quality pictures than CT. CT and MRI demonstrated a good correlation in the detection of mucosal pathologies ({kappa}=0.46-0.87) and anatomic variants ({kappa}=0.55-0.86). All important anatomical structures could be evaluated sufficiently with MRI for preoperative management. Both diagnostic tools showed an unsatisfactory correlation with intraoperative findings in the ethmoidal complex and maxillary sinus ({tau}=-0.08-0.3). (orig.)

    Depending on the problems, CT or MRI should be used in the differential diagnosis of conditions affecting the nasal sinuses. In particular, when chronic sinusitis is present, computed tomography should be performed before surgery to ascertain the condition of the bones. In most cases spiral CT with a decidedly lowered tube voltage and power (MAS product) is now used for this purpose. This means that the patient is exposed to about 70% less radiation than in other CT investigations. To avoid artefacts attributable to dental fillings, whenever possible the spiral should be tilted in such a way that the dental artefacts are not within the mass imaged. When an isotropic voxel is selected secondary reformatting is possible with no loss of quality. Diagnostic MRI should include both T1- and T2-weighted sequences before and after the administration of contrast agent. For the differential diagnosis of a space-occupying tumour coronal cuts about 2 mm apart are advised, whether the spiral or the conventional technique is used. A T2-weighted and fat-suppressed sequence or a STIR (short tau inversion recovery) sequence can also be helpful in the recognition and visualization of lymph nodes. If orbital involvement seems possible it is advisable to use a T1-weighted and fat-suppressed sequence in the coronal plane in addition to check this. (orig.) [German] Bei der differenzialdiagnostischen Evaluierung der Nasennebenhoehlen sollte je nach Fragestellung neben der klinischen Evaluierung die Computertomographie (CT) oder Magnetresonanztomographie eingesetzt werden.

Heutzutage wird man hier zumeist eine Spiral-CT mit deutlich reduzierte Roehrenspannung und Strom (MAS-Produkt) zurueckgreifen. So koennen bis zu 70% Strahlung gespart werden.

    Objective: This study was designed to compare the efficacy of crystallized phenol method with Limberg flap in pilonidal sinus treatment. Material and Methods: Patients with a diagnosis of pilonidal sinus disease treated with surgical excision + Limberg rhomboid flap technique and crystallized phenol method between 2010–2011 in the Şevket Yılmaz Training and Research Hospital, Department of General Surgery were evaluated retrospectively. Patients’ age, sex, length of hospital stay, complications and recurrence rates were evaluated. Results: Eighty eight percent of patients were male and mean age was 26.84±6.41 in the Limberg group, and 24.72±5.00 in the crystallized phenol group. Sinus orifice locations and nature, and duration of symptoms before surgery were similar in the two groups. Length of hospital stay in the Limberg group was 1.46±0.61 days; whereas all patients in the crystallized phenol group were discharged on the same day. Infection, hematoma, wound dehiscence, and cosmetic problems were significantly higher in the Limberg group. There was no difference between the two groups in terms of recurrence and seroma formation. Conclusion: The less invasive method of crystallized phenol application may be an alternative approach to rhomboid excision and Limberg flap in patients with non-complicated pilonidal sinus disease, yielding acceptable recurrence rates.

    Full Text Available Implants have a predictable outcome and are the foremost treatment modality for prosthetic rehabilitation of edentulous patients. Due to loss of bone after extraction and pneumatization of maxillary sinus, there is insufficient bone volume for implant placement. The direct maxillary sinus lift procedure has been performed with different grafting materials (autogenous bone grafts, alloplasts, allografts, and xenografts and without grafting material, having new bone formation around the implant. There is no evidence to prove the need for grafting material in all direct sinus lift procedures, hence the need for this review. Previous meta-analysis showed that survival rates of implants placed in grafted maxillary sinuses had similar survival rates whether autogenous, allogenous, or alloplastic grafts were used. This paper aims to review scientific data on the direct sinus elevation technique without use of any grafting material, volume of new bone formed, and also mechanism behind this technique. Articles were searched from 1997 to October 2014 in PubMed, Google Scholar, and Cochrane CENTRAL. The study eligibility criteria were (1 direct sinus lift procedure without any graft material during implant placement and (2 human or animal studies with a minimum follow-up of 6 months or more. Two authors independently scrutinized the literature and if any controversy was raised, third author's opinion was sought to arrive at a mutual consensus for including the study in the review. Due to the heterogeneity across all studies in all study designs, the data were not pooled and a meta-analysis was not performed. Taking into consideration all factors reviewed in this regard along with the outcomes, the direct sinus lift technique without grafting can be suggested as a viable treatment option keeping in mind the limitations involved. The average bone gain was seen across all studies ranging from 2.37 to 10 mm and with an implant survival rate ranging from 79

    Several experimental studies have shown osteitis after the onset of sinusitis, supporting the idea that bone involvement could participate in the dissemination and perpetuation of this inflammatory disease. However, procedures commonly performed for the induction of sinusitis, such as antrostomies, can trigger sinusitis by themselves. To evaluate osteitis in an animal model of sinusitis that does not violate the sinus directly and verify whether this is limited to the induction side, or if it affects the contralateral side. Experimental study in which sinusitis was produced by inserting an obstructing sponge into the nasal cavity of 20 rabbits. After defined intervals, the animals were euthanized and maxillary sinus samples were removed for semi-quantitative histological analysis of mucosa and bone. Signs of bone and mucosal inflammation were observed, affecting both the induction and contralateral sides. Statistical analysis showed correlation between the intensity of osteitis on both sides, but not between mucosal and bone inflammation on the same side, supporting the theory that inflammation can spread through bone structures, regardless of mucosal inflammation. This study demonstrated that in an animal model of sinusitis that does not disturb the sinus directly osteitis occurs in the affected sinus and that it also affects the contralateral side.

    Background Blood eosinophil and basophil levels have recently been considered for the purpose of endotyping chronic rhinosinusitis with nasal polyps (CRSwNP). Histologically, eosinophilic-type CRSwNPs have been associated with high recurrence rates after treatment. Objective The present study was the first to compare blood eosinophil and basophil counts in eosinophilic-type CRSwNP patients before and after endoscopic sinus surgery. Methods The study concerned 79 consecutive patients with histologically confirmed eosinophilic-type CRSwNP treated with endoscopic sinus surgery. Results A significant drop in mean blood eosinophil counts and percentages occurred from before to after endoscopic sinus surgery in the cohort as a whole. Mean blood eosinophil counts and percentages were also reduced after surgery in the subcohorts of CRSwNP patients with (i) asthma, (ii) aspirin-exacerbated respiratory disease (AERD), and (iii) no allergy. Although blood eosinophil and basophil counts correlated directly before and after surgery, a statistical reduction in blood basophil counts and percentages after surgery emerged only in the subcohort of nonallergic CRSwNP patients. Conclusion Endoscopic sinus surgery can clear polyps, remove inflammatory tissue, and reduce inflammatory cytokine levels. Consistently with the biological mechanism described, endoscopic sinus surgery could coincide with a reduction in blood eosinophils in eosinophilic-type CRSwNP.

    Full Text Available Periorbital soft tissue swelling may result due to primary orbital pathology or from adjacent facio-maxillary or sino-nasal inflammatory causes. Osteomyelitis of maxilla in the pediatric age group is a rare entity in this era of antibiotics. We present an 11-month-old female infant who was brought with peri-orbital selling and purulent nasal discharge. Computed Tomography showed erosions of the walls of maxillary sinus suggestive of osteomyelitis. Culture of sinus scraping showed Staphylococcus aureus growth and the child improved with intravenous cloxacillin therapy. This case is presented due to the rarity of its presentation in this age group and for awareness to consider this entity in children having fever and peri-orbital swelling.

    Cavernous sinus syndrome (CSS) is a rare condition characterised by ophthalmoplegia, proptosis, ocular and conjunctival congestion, trigeminal sensory loss and Horner's syndrome. These signs and symptoms result from the involvement of the cranial nerves passing through the cavernous sinus. We report the case of a 53-year-old man with a history of daily stabbing headache associated with dizziness, progressive blurred vision, right ocular pain, ptosis and ophthalmoplegia. After working up the patient, a meningioma was identified as the cause of the CSS. Despite advances in neuroimaging techniques, in some cases, the aetiology of CSS remains difficult to determine. We highlight the clinical and radiological features of a meningioma, one of the causes of CSS. Early diagnosis and treatment of CSS play a key role in a better prognosis. 2015 BMJ Publishing Group Ltd.

    Full Text Available Lateral sinus thrombosis (LST is usually occurs as a complication of middle ear infection .The involvement of lateral sinus during the course of ear infection was a well known complication in preantibiotic days .The decrease in the incidence of LST is due to the introduction of broad-spectrum antibiotics, early diagnosis and surgical treatment. Now, it is a rare complication of otitis media and poses a serious threat that warrants immediate medical and surgical treatment. The classical clinical picture is often changed by previous antibiotic therapy. An awareness of this rare potentially devastating condition and its varied presentations is necessary for early diagnosis and treatment. LST can also occur after head injury.

    Background: We report the recovery of ophthalmoplegia in 11 patients with cavernous sinus dural arteriovenous fistula (CSDAVF) after sinus packing at follow-up. Methods: Of 18 patients with CSDAVF treated with transvenous cavernous sinus packing between August 2002 and December 2007 at Beijing Tiantan Hospital, there were 9 patients with initial CNIII or CNVI dysfunction and 2 patients with CNVI dysfunction immediately after cavernous sinus packing selected and reevaluated. Results: Of 11 patients with CNIII or CNVI palsy, recovery was complete in 10. In 1 patient, complete CNVI palsy was unchanged because the CSDAVF was not cured. There were 6 men and 5 women with a mean age of 52.9 years. In 5 patients, CNVI palsy was associated with chemosis, proptosis and pulsatile tinnitus. Timing of treatment after onset of symptoms was from 4 to 35 days in 9 patients. All CSDAVFs were Barrow type D. Mean follow-up after treatment was 17.7 months (range, 2-54 months). Conclusion: CSDAVF-induced CNIII or CNVI palsies can be cured after cavernous sinus packing transvenously in most patients.

    Five of 34 patients (ages 4-21 years), who were subsequently diagnosed histologically as having fibrous dysplasia of the maxillary sinus, rapidly developed soft tissue masses of the malar region over a period of less than 4 months with accompanying pain (2 patients) and nasal obstruction and exophthalmos (2 patients). Each was clinically suspected of having a sarcoma. After resection, all lesions developed regrowth. At histopathologic examination, both initial and recurrent masses proved to be typical fibrous dysplasia. (orig./UWA)
