Traditional nasoalveolar molding (NAM) requires steep learning curve for clinicians and significant compliance from parents. Nasal springs have been developed by the author to simplify presurgical nasal molding. This article presents the design, construction, and application of the spring. The treatment goal is to improve nasal deformity prior to primary repair in infants born with incomplete unilateral cleft lip with or without cleft palate. The design, fabrication, and utility of the nasal spring are described. The spring has a simpler design and construction compared to a traditional NAM appliance. Two patients with incomplete unilateral cleft lip with and without cleft palate are presented. The spring is constructed and delivered. The active arm of the spring can be 3-dimensionally (3-D) adjusted to mold the alar cartilage of the affected nostril. The spring does not require an oral plate for adherence as a traditional NAM appliance does, hence an oral impression is not needed. The spring is easy for clinicians to adjust. It also requires less compliance by parents. Main Outcome Measures/Results: The presurgical molding achieved by the use of a nasal spring improved surgical nasolabial aesthetic outcomes. The nasal springs are effective in reducing the initial cleft nasal deformity. This facilitates primary surgical cleft lip and nose correction and improves surgical outcomes in patients with incomplete unilateral cleft lip with or without cleft palate.

The aim of the study was to investigate self-experienced nasal symptoms among adults treated for UCLP and the association to clinical findings, and to evaluate whether palate closure in one-stage or two-stages affected the symptoms or clinical findings. All people with UCLP born between 1960-1987, treated at Uppsala University Hospital, were considered for participation in this cross-sectional population study with long-term follow-up. Eighty-three patients (76% participation rate) participated, a mean of 37 years after the first operation. Fifty-two patients were treated with one-stage palate closure and 31 with two-stage palate closure. An age-matched group of 67 non-cleft controls completed the same study protocol, which included a questionnaire regarding nasal symptoms, nasal inspection, anterior rhinoscopy, and nasal endoscopy. Patients reported a higher frequency of nasal symptoms compared with the control group, e.g., nasal obstruction (81% compared with 60%) and mouth breathing (20% compared with 5%). Patients also rated their nasal symptoms as having a more negative impact on their daily life and physical activities than controls. Nasal examination revealed higher frequencies of nasal deformities among patients. No positive correlation was found between nasal symptoms and severity of findings at nasal examination. No differences were identified between patients treated with one-stage and two-stage palate closure regarding symptoms or nasal findings. Adult patients treated for UCLP suffer from more nasal symptoms than controls. However, symptoms are not associated with findings at clinical nasal examination or method of palate closure.

Thick nasal skin presents a challenge in rhinoplasty. Conventional spreader grafts in patients with thick nasal skin may result in an undesirable widening of the lower half of the nose where the nasal skin is thick. The use of short spreader grafts was evaluated in patients with thick nasal skin. For this study, 32 patients underwent closed rhinoplasty in which short spreader grafts were used. The spreader graft was 1 to 2 cm long and extended only to the transition of thin and thick nasal skin. The patients were followed for more than 1 year postoperatively. Aesthetic improvement was observed in all the patients. Nasal airway patency was improved or maintained in 94 % of the patients. Short spreader grafts effectively restore or maintain the internal nasal valve area after dorsal hump reduction while allowing for more aggressive narrowing of the lower part of the nose where nasal skin is thick.

2013-01-01

Introduction The current mainstream practice in otolaryngology departments relating to the use of prophylactic antibiotics in epistaxis patients requiring nasal packing is highly variable. This is due primarily to the lack of any validated guidelines. As such, we introduced a new treatment algorithm resulting in significant reduction of use in the systemic antibiotics, with emphasis instead on the use of topical antibiotics. The results were validated through a complete audit cycle. Methods A total of 57 patients undergoing nasal packing for spontaneous epistaxis were studied. Reaudit occurred after the implementation of new guidelines. Telephone surveys were conducted six weeks after hospital discharge, assessing infective nasal symptoms as well as rebleeding and readmission rates. Results Systemic antibiotic prescribing in anterior nasal packing fell by 58.2% between audit cycles with no statistically significant associated increase in infective nasal symptoms, rebleeding or readmission rates six weeks following hospital discharge. Conclusions Systemic prophylactic antibiotics are unnecessary in the majority of epistaxis patients with nasal packs. The use of topical antibiotics such as Naseptin® may be more appropriate, cheaper and as effective. Implementation of this treatment algorithm will help standardise systemic antibiotic usage in epistaxis patients with nasal packing and should reduce costs associated with unnecessary use of such medication.

The authors present a case of nasal chondromesenchymal hamartoma (NCMH) in an 8-year-old boy with a 4-month history of frontal headache and no symptoms of nasal obstruction, rhinorrhoea or postnasal drip. An ENT examination as well as ophthalmology assessment presented normal results. CT scan showed a lesion involving the sphenoid and ethmoid sinuses. The patient had an endoscopic resection of the lesion that was confirmed histologically to be a NCMH. Though NCMH is known to present usually in infants with obstructing nasal mass, an unusual presentation of a patient with throbbing headache without any nasal symptoms is reported here.

Nasal packing is an option for bleeding control after endoscopic sinus surgery and septoplasty. Although new packing materials have been developed, patients still suffer from pain and require additional analgesics treatments. In this study, a prospective, randomized, and double-blind controlled trial was designed to evaluate the effect of fentanyl-soaked packing on pain after endoscopic sinus surgery and septoplasty. One hundred fifty-two patients who underwent nasal surgeries due to chronic rhinosinusitis or nasal septal deviation were enrolled in this study. At the end of operation, 50 mcg fentanyl-soaked biodegradable synthetic polyurethane foams packing Nasopore or Merocel were applied to a group of 79 patients, and saline-soaked ones were applied to another group of 73 patients. To evaluate the influence of fentanyl on postoperative nasal pain, patients' conditions were assessed via means of Numeric Rating Scale, patient satisfaction, and Ramsay Sedation Scale. In addition, symptoms of headache or sore throat and any signs of cardiopulmonary-relevant indicators were monitored. The fentanyl group had significantly decreased Numeric Rating Scale and increased patient satisfaction in every operation type for the majority of postoperative time periods ( P fentanyl group showed a higher score on Ramsay Sedation Scale than the control group ( P .05). Fentanyl group showed significantly reduced postoperative pain without serious adverse effects. We suggest that topical fentanyl application to nasal packs can be a useful method to reduce pain during the early postoperative period after endoscopic sinus surgery and septoplasty.

Continuous positive airways pressure (CPAP) for treatment of obstructive sleep apnea (OSA) can produce troublesome nasal symptoms (i.e. congestion, rhinorrhea) that may reduce the compliance of CPAP. Topical nasal steroids are often prescribed to reduce these side effects, although scientific data are scarce supporting any benefits of this treatment for CPAP-induced nasal side effects. To study whether a topical nasal steroid can reduce CPAP-induced nasal symptoms and improve CPAP adherence during the initial phase of OSA treatment. A randomized, double-blinded, placebo-controlled study with fluticasone propionate 100 μg/nasal cavity twice daily Treatment was started 10 days prior to and continued throughout the first 4 weeks of CPAP. 63 patients who were selected for CPAP treatment participated. Nasal symptoms were recorded, nasal patency was assessed and lung function was measured with a peak flow meter. The patients' adherence to CPAP was recorded by the CPAP device. Total nasal symptoms increased from baseline to 4 wks after CPAP use for both nasal treatments (p < 0.05). No differences in total nasal symptoms between treatments were seen (p = 1), and no differences in nasal peak flow values after treatment were seen (p = 0.11). Moreover, there were no differences in CPAP use between the treatments. Fluticasone propionate as a nasal topical steroid does not reduce CPAP-induced unwanted nasal side effects, and has no beneficial effect on CPAP compliance during the first four weeks of treatment in unselected patients with OSAS.

Device-related pressure ulcers from noninvasive ventilation masks alter skin integrity and cause patients discomfort. To examine the incidence, location, and stage of pressure ulcers and patients' comfort with a nasal-oral mask compared with a full-face mask. A before-after study of a convenience sample of patients with noninvasive ventilation orders in 5 intensive care units was conducted. Two groups of 100 patients each received either the nasal-oral mask or the full-face mask. Skin was assessed before the mask was applied and every 12 hours after that or upon mask removal. Comfort levels were assessed every 12 hours on a Likert scale of 1 to 5 (1, most comfortable). A pressure ulcer developed in 20% of patients in the nasal-oral mask group and 2% of patients in the full-face mask group (P face mask (mean [SD], 1.9 [1.1]) than with the nasal-oral mask (mean [SD], 2.7 [1.2], P face mask and 25 (SD, 20.7) and 92% for nasal-oral mask. No patients who had a pressure ulcer develop with the nasal-oral mask had a pressure ulcer develop with the full-face mask. The full-face mask resulted in significantly fewer pressure ulcers and was more comfortable for patients. The full-face mask is a reasonable alternative to traditional nasal-oral masks for patients receiving noninvasive ventilation. ©2015 American Association of Critical-Care Nurses.

In determining patient satisfaction with functional and aesthetic outcome after reconstructive surgery, including nasal reconstruction, standardised assessment instruments are very important. These standardised tools are needed to adequately evaluate and compare outcome results. Since no such instrument existed for nasal reconstruction, a standardised evaluation questionnaire was developed to assess aesthetic and functional outcome after nasal reconstruction. Items of the Nasal Appearance and Function Evaluation Questionnaire (NAFEQ) were derived from both the literature and experiences with patients. The NAFEQ was validated on 30 nasal reconstruction patients and a reference group of 175 people. A factor analysis confirmed the arrangement of the questionnaire in two subscales: functional and aesthetic outcome. High Cronbach's alpha values (>0.70) for both subscales showed that the NAFEQ was an internally consistent instrument. This study demonstrated that the NAFEQ can be used as a standardised questionnaire for detailed evaluation of aesthetic and functional outcome after nasal reconstruction. Its widespread use would enable comparison of results achieved by different techniques, surgeons and centres in a standardised fashion.

To determine whether the presence of nasal flaring is a clinical sign of severity and a predictor of hospital mortality in emergency patients with dyspnea. Prospective, observational, single-center study. We enrolled patients older than 15 years of age who required attention for dyspnea categorized as level II or III emergencies according to the Andorran Medical Triage system. Two observers evaluated the presence of nasal flaring. We recorded demographic and clinical variables, including respiratory effort, vital signs, arterial blood gases, and clinical course (hospital admission and mortality). Bivariable analysis was performed and multivariable logistic regression models were constructed. We enrolled 246 patients with a mean (SD) age of 77 (13) years; 52% were female. Nasal flaring was present in 19.5%. Patients with nasal flaring had triage levels indicating greater severity and they had more severe tachypnea, worse oxygenation, and greater acidosis and hypercapnia. Bivariable analysis detected that the following variables were associated with mortality: age (odds ratio [OR], 1.05; 95% CI, 1.01-1.10), prehospital care from the emergency medical service (OR, 3.97; 95% CI, 1.39-11.39), triage level II (OR, 4.19; 95% CI, 1.63-10.78), signs of respiratory effort such as nasal flaring (OR, 3.79; 95% CI, 1.65-8.69), presence of acidosis (OR, 7.09; 95% CI, 2.97-16.94), and hypercapnia (OR, 2.67; 95% CI, 1,11-6,45). The factors that remained independent predictors of mortality in the multivariable analysis were age, severity (triage level), and nasal flaring. In patients requiring emergency care for dyspnea, nasal flaring is a clinical sign of severity and a predictor of mortality.

To investigate the clinical features and management of intractable deep-seated epistaxis. Clinical data were analyzed retrospectively in 195 patients with intractable deep-seated epistaxis treated in Affiliated Hospital of Qingdao College between June 2008 and June 2014. The analyses included common risk factors, bleeding sites, treatments and therapeutic effects. SPSS 17.0 software was used to analyze the data. There were 162 males and 33 females, aged from 15 to 88 years old (mean 52 ± 16 years). One hundred and eighty-seven cases (95.9%) were unilateral and 8 cases (4.1%) were bilateral. One hundred and twenty-six cases (64.6%) had the history of hypertension or blood pressure higher than normal on admission. Eight patients were cured by nasal packing and appropriate drugs, and 187 patients were treated by endoscopy and electrocoagulation. The numbers of treatment needed to stop bleeding were 1 time in 184 cases (98.4%), 2 times in 3 cases (1.6%). Thirteen cases did not have certain bleeding point, while the other 174 had certain one or more bleeding sites. The rewarded bleeding sites were 222, which were found in the following different sites: posterior inferior nasal meatus (33.3%, 74 /222), olfactory cleft of nasal septum (26.6%, 59/222), the root of the middle turbinate (14.0%, 31/222), and so on. Hypertension and diabetes were risk factors (OR value was 3.411, 7.142, both P epistaxis are mainly found in males and are almost unilatera1. Hypertension and diabetes are the common risk factor. The most effective and safe treatment for intractable deep-seated epistaxis is electrocoagulation under nasal endoscopy.

Full Text Available Transnasal endoscopy is widely used in screening for upper gastrointestinal lesions because of less associated pain. Nasal bleeding is the most severe adverse effect, but specific risk factors have not been identified. The aim of this study is to identify risk factors for nasal bleeding during transnasal endoscopy. Nasal bleeding occurred in 160/3035 (5.3% of patients undergoing transnasal endoscopy as part of health checkups. Patient data were retrospectively evaluated including anthropometric, medical, and life-style parameters with multiple logistic regression analysis. Multiple logistic regression revealed that nasal bleeding was significantly associated with age in decades [odds ratio/10 years 0.78, 95% confidence interval (CI 0.63–0.97, p = 0.027], female gender (2.15, 95% CI 1.48–3.12, p < 0.001, a history of previous upper gastrointestinal endoscopy (0.55, 95% CI 0.36–0.82, p = 0.004, and chronic/allergic rhinitis (0.60, 95% CI 0.36–0.98, p = 0.043. Other factors including the use of antiplatelet and/or anticoagulant drugs were not significantly associated with nasal bleeding. Female and young patients are significantly associated with an increased risk of bleeding from transnasal endoscopy, but antiplatelet and/or anticoagulant medications and a history of chronic/allergic rhinitis may not be associated.

The reliability of X-ray radiography for diagnosing nasal bone fractures (NBFs) remains controversial. Recent studies show that, for determining the orientation and location of the displaced/depressed fracture, nasal sonography is as accurate as facial computed tomography. This retrospective study compared conductor-assisted nasal sonography (CANS) to conventional diagnostic tools and reported subjective patient satisfaction and discomfort after closed reduction combined with tube technique. This retrospective study reports the results of 329 refinement treatments for nasal bone fracture (including 199 men and 130 women) performed from 2005 to 2011. All patients were assessed with CANS and completed a survey immediately prior to removing the packing. Questionnaires were adapted from the nasal obstruction symptom evaluation (NOSE) scale. The study found that CANS has a 97.2% rate of accuracy in diagnosing NBF. The visual analog scale scores of nasal obstruction, nasal congestion, sleep disturbance, trouble breathing, and inability to move air through the nose were analyzed. The experimental group scores were significantly different from the control group for all scores (p tube technique balances pressure between the nasopharynx and middle ear during swallowing, patient comfort is enhanced. Application of these modifications can improve accuracy in diagnosing NBF and can improve the quality of NBF treatment. Copyright © 2014. Published by Elsevier Taiwan.

REVIEW OF NASAL CHANGES WITH MAXILLARY ORTHOGNATHIC SURGERY

Leila KHAMASHTA-LEDEZMA

2017-02-01

Full Text Available This article reviews the literature on nasal changes with maxillary orthognathic surgery. Understanding such changes is vital for surgical planning and for obtaining appropriate informed consent, and there are medico-legal implications. During orthognathic surgical planning a prediction of the effects of the different surgical movements is possible and this forms part of the basis of the planning stage. The predicted changes need to be identified and their desirability or not for each individual patient determined. Some techniques for managing undesirable nasal changes are discussed, including adjunct measures to minimize these potential effects (e.g. cinch sutures, and additional surgical procedures to manage the undesired nasal changes once they are produced.

Orthognathic surgery alters the position of maxilla and mandible, and consequently changes the nasal shape. The nasal change remains a concern to Asian patients. The aim of this study was to measure the nasal changes using a novel three-dimensional photographic imaging method. A total of 38 patients with Class III malocclusion and prognathism were enrolled. All patients underwent two-jaw surgery with the standard technique. A nasal alar cinching suture was included at the end of procedure. Facial landmarks and nasal morphology were defined and measured from pre- and postoperative three-dimensional photographic images. Intra-rater errors on landmark identification were controlled. Patient's reports of perceptual nasal changes were recorded. The average width of the alar base and subalare remained similar after surgery. Alar width was increased by 0.74 mm. Nasal height and length remained the same. Nasolabial angle increased significantly. The area of nostril show revealed a significant increase and was correlated with a decrease of columella inclination. Nasal tip projection decreased significantly, by 1.99 mm. Preoperative nasal morphology was different between patients with and without cleft lip/palate, but most nasal changes were concordant. In the self-perception, 37% of patients reported improved nasal appearance, 58% reported no change, and 5% were not satisfied with the nasal changes. After the surgery, characteristic nasal changes occurred with an increase of nasolabial angle and nostril show, but a preserved nasal width. The majority of patients did not perceive adverse nasal changes. Copyright © 2014. Published by Elsevier B.V.

To evaluate the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage in patients with diabetic foot ulcer (DFU) in Taiwan, and to assess the concordance between colonizing and clinical MRSA isolates from the patients. A total of 354 nasal specimens were collected from 112 to 242 diabetic patients with and without foot ulcer, respectively. MRSA clinical isolates from DFU wound cultures were collected for comparison. Nasal carriage rate of S. aureus and MRSA was similar between diabetic patients with and without foot ulcer (15.2% vs. 16.9% for S. aureus and 5.4% vs. 1.7% for MRSA). Nasal S. aureus colonization was an independent predictor for wound S. aureus infection (Odds ratio [OR]: 5.33, 95% confidence interval [CI]: 1.61-17.59), so did nasal MRSA colonization (OR: 19.09, 95% CI: 2.12-171.91). The levels of glycated hemoglobin, and the usage with immunosuppressant agent were associated with S. aureus nasal colonization while oral hypoglycemic agent usage a protective factor. Sequence type 59/staphylococcal chromosome cassette mec IV or V, the local endemic community-associated clone, accounted for 42% and 70% of the clinical and colonizing isolates, respectively. Six of 10 patients with paired colonizing and clinical isolates, either MRSA or methicillin-sensitive S. aureus, had a genetically identical strain from a single patient. Less than one-fifth of patients with DFU have nasal S. aureus, including MRSA, colonization; however, the colonization is significantly associated with S. aureus diabetic foot infection. Screening for S. aureus colonizing status in DFU patients might have a potential clinical implication. Copyright © 2018. Published by Elsevier B.V.

Nasal highflow improves ventilation in patients with COPD

Bräunlich J

2016-05-01

Full Text Available Jens Bräunlich,* Marcus Köhler,* Hubert WirtzDepartment of Respiratory Medicine, University of Leipzig, Leipzig, Germany *These authors contributed equally to this workBackground: Nasal highflow (NHF provides a warmed and humidified air stream up to 60 L/min. Recent data demonstrated a positive effect in patients with acute hypoxemic respiratory failure, especially when caused by pneumonia. Preliminary data show a decrease in hypercapnia in patients with COPD. Therefore, NHF should be evaluated as a new ventilatory support device. This study was conducted to assess the impact of different flow rates on ventilatory parameters in patients with COPD.Materials and methods: This interventional clinical study was performed with patients suffering from severe COPD. The aim was to characterize flow-dependent changes in mean airway pressure, breathing volumes, breathing frequency, and decrease in partial pressure of CO2 (pCO2. Mean airway pressure was measured in the nasopharyngeal space (19 patients. To evaluate breathing volumes, we used a polysomnographic device (18 patients. All patients received 20 L/min, 30 L/min, 40 L/min, and 50 L/min and – to illustrate the effects – nasal continuous positive airway pressure and nasal bilevel positive airway pressure. Capillary blood gas analyses were performed in 54 patients with hypercapnic COPD before and two hours after the use of NHF. We compared the extent of decrease in pCO2 when using 20 L/min and 30 L/min. Additionally, comfort and dyspnea during the use of NHF were surveyed.Results: NHF resulted in a minor flow dependent increase in mean airway pressure. Tidal volume increased, and breathing rate decreased. The calculated minute volume decreased under NHF breathing. In spite of this fact, hypercapnia decreased with increasing flow (20 L/min vs 30 L/min. Additionally, an improvement in dyspnea was observed. The rapid shallow breathing index shows a decrease when using NHF.Conclusion: NHF

Background: Nasal side effects are common in patients with obstructive sleep apnea syndrome (OSAS) starting on nasal continuous positive airway pressure (CPAP) therapy. We tested the hypothesis that heated humidification or nasal topical steroids improve compliance, nasal side effects and quality of life in this patient group. Methods: 125 patients with the established diagnosis of OSAS (apnea/hypopnea index ≥ 10/h), who tolerated CPAP via a nasal mask, and who had a successful CPAP titration were randomized to 4 weeks of dry CPAP, humidified CPAP or CPAP with additional topical nasal steroid application (fluticasone, GlaxoWellcome). Groups were similar in all demographic variables and in frequency of nasal symptoms at baseline. Outcome measures were objective compliance, quality of life (short form 36), subjective sleepiness (Epworth Sleepiness Scale score) and nasal symptoms such as runny, dry or blocked nose, sneezing and headaches; all variables assessed using a validated questionnaire and by direct interview. Results: There was no difference in compliance between groups after 4 weeks (dry: 5.21 ± 1.66 h/night, fluticasone: 5.66 ± 1.68, humidifier: 5.21 ± 1.84; p = 0.444). Quality of life and subjective sleepiness improved in all groups, but there were no differences in the extent of improvement. Nasal Symptoms were less frequently reported in the humidifier group (28%) than in the remaining groups (dry: 70%, fluticasone: 53%, p = 0.002). However, the addition of fluticasone resulted in increased frequency of sneezing. Conclusion: The addition of a humidifier, but not nasal steroids decreases the frequency of nasal symptoms in unselected OSAS patients initiating CPAP therapy; however compliance and quality of life remain unaltered.

Epistaxis is the most common ENT emergency encountered in the Emergency Department. Most cases can be managed by simple anterior nasal packing. This is usually a safe and very effective option in an emergency situation, requiring minimal expertise and infrastructure. This paper describes a rare instance of a serious complication following anterior nasal packing in a case of nasopharyngeal angiofibroma. A 27-year-old man diagnosed with nasopharyngeal angiofibroma presented to the Emergency Department with bilateral epistaxis. The patient was stabilised and anterior nasal packing was performed, which controlled the bleeding. Three hours later, the patient developed complete blindness in both eyes. Aggressive medical management was initiated immediately, but failed to restore the patient's vision. Anterior nasal packing is a simple and minimally invasive procedure practised regularly in an Emergency Department setting. However, it can occasionally lead to serious complications such as blindness. Thus, obtaining informed consent is essential to avoid medico-legal consequences in high-risk cases.

BACKGROUND: Nasal side effects are common in patients with obstructive sleep apnea syndrome (OSAS) starting on nasal continuous positive airway pressure (CPAP) therapy. We tested the hypothesis that heated humidification or nasal topical steroids improve compliance, nasal side effects and quality of life in this patient group. METHODS: 125 patients with the established diagnosis of OSAS (apnea\\/hypopnea index > or = 10\\/h), who tolerated CPAP via a nasal mask, and who had a successful CPAP titration were randomized to 4 weeks of dry CPAP, humidified CPAP or CPAP with additional topical nasal steroid application (fluticasone, GlaxoWellcome). Groups were similar in all demographic variables and in frequency of nasal symptoms at baseline. Outcome measures were objective compliance, quality of life (short form 36), subjective sleepiness (Epworth Sleepiness Scale score) and nasal symptoms such as runny, dry or blocked nose, sneezing and headaches; all variables assessed using a validated questionnaire and by direct interview. RESULTS: There was no difference in compliance between groups after 4 weeks (dry: 5.21 +\\/- 1.66 h\\/night, fluticasone: 5.66 +\\/- 1.68, humidifier: 5.21 +\\/- 1.84; p = 0.444). Quality of life and subjective sleepiness improved in all groups, but there were no differences in the extent of improvement. Nasal Symptoms were less frequently reported in the humidifier group (28%) than in the remaining groups (dry: 70%, fluticasone: 53%, p = 0.002). However, the addition of fluticasone resulted in increased frequency of sneezing. CONCLUSION: The addition of a humidifier, but not nasal steroids decreases the frequency of nasal symptoms in unselected OSAS patients initiating CPAP therapy; however compliance and quality of life remain unaltered.

Recent study showed that patients with acromegaly have typical skin findings including increased sebum secretion, decreased transepidermal water loss, more alkaline, and colder skin surface correlated with serum growth hormone and insulin-like growth factor 1 levels. Different anatomic localizations and texture of the skin differ in bacterial concentrations.Nasal carriage of Staphylococcus aureus and axillar flora in patients with acromegaly was compared with normal population with regard to duration of acromegaly as well as the growth hormone and insulin-like growth factor 1 levels. This patient-control prospective study was conducted in university hospitals in Mersin, Turkey. The study consisted of 30 active acromegalic patients and 60 healthy adults who had no previously diagnosed chronic illness as a control group. A total of 90 volunteers were enrolled in this study; nasal and axillar cultures were obtained. Axillar and nasal specimens from anterior nares of the individuals were taken using sterile swabs. Nasal colonization of Staphylococcus aureus was 13.3% in acromegalic patients, but 43.4% in control group. This difference was statistically significant (P = 0.004). Patients and control group compared according to axillar cultures, the authors determined proteus colonization 16.7% in patients with acromegaly but no proteus colonization in control group. This result was statistically significant (P = 0.001). Proteus colonization was negatively correlated only with disease duration in acromegalic patients (P = 0.017). The authors demonstrated that compared with healthy subjects, acromegalic patients had low percentage of nasal carriage of Staphylococcus aureus and more gram-negative basili in the axillar flora. These nasal and axillar flora changes should be considered for prophylactic antibiotics use before surgery and ampiric antibiotics use after surgery.

Full Text Available Background. Combined airway hyper responsiveness to cold and hypoosmotic stimuli in asthma patients results in impairment of lung respiration function and poor disease control compared to patients with isolated airway hyper responsiveness to only one of the stimuli or without such responsiveness that can be connected with edema or mucus hypersecretion.Aim. The purpose of the study is the estimation of the processes of mucin secretion, plasma exudation and oxidative stress in response to cold air in asthma patients with combined airway responsiveness to cold and hypoosmotic stimuli using nasal mucosa as a model.Materials and methods. 23 patients with asthma participated in the study. For the nasal lavage procedure, a nasal cavity was pre-washed at least three times in 5-min intervals with 5 ml saline solution (~36 °C. A control nasal lavage was done 5 min after the last washing with a dwelling time of 1 min in the nasal cavity. Directly after the control lavage, a cold air nasal challenge was done: a participant was asked to breathe deeply at the pace of a metronome to ensure hyperventilation inhaling cold air (–20 °C through the nose and exhaling through the mouth for 5 min. Nasal lavages were taken at 1 min, 15, and 30 min after the challenge. Mucin secretion was estimated on the basis of total protein (TP content, total carbohydrates (TC, and water-soluble forms of mucins MUC5AC and MUC5B in the lavage fluids. For the estimation of plasma exudation, the concentration of α2-macroglobulin (α2-MG was measured. Oxidative stress was estimated by the content of thiobarbituric acid-reactive substances (TBARS in lavage fluid. Lung function and airway responsiveness were studied by the forced expiration spirometry method and the bronchial challenge tests with isocapnic cold air hyperventilation (CAHV and distilled water inhalation (DWI.Results. According to the bronchial challenge tests, the patients were divided into groups: 1 without airway

Antiresorptive drugs have been widely used to treat patients with hypercalcemia caused by malignancy, bone metastasis, multiple myeloma, and osteoporosis. However, it is well known that antiresorptive drugs can cause osteonecrosis of the jaw (ONJ). Herein, we report a rare case of nasal septal abscess caused by medication related osteonecrosis of the jaw (MRONJ) in a breast cancer patient. A 69-year-old woman was referred to our clinic for evaluation of nasal obstruction. Physical examination revealed a cherry-like swelling of the nasal mucosa emanating from the septum that obstructed both nasal cavities and a fistulous tract showing pus discharge after extraction of the bilateral maxillary central incisors (MCI) and the right maxillary lateral incisor (MLI). Computed tomography and panoramic radiography revealed extensive osteonecrosis of the maxilla and swelling of the nasal mucosa. The clinical diagnosis was nasal septal abscess caused by osteonecrosis of the maxilla. Surgical procedure was undertaken for this case. An indwelling drain was placed in the oral cavity, and sequestrectomy was performed with incision and drainage of the anterior portion of left nasal septum. The patient was doing well at the 7-month follow-up. The patient had a medical history of breast cancer with bone, lung, liver metastases, and had received intravenous bisphosphonate, which is one of the antiresorptive medicines, over the past 4 years. We suspect that this history played an important role in MRONJ induced nasal septal abscess. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Paradoxical sensation of nasal airflow in patients with common cold. Are we measuring the correct modality?

A paradoxical relationship between objective and subjective measures of nasal obstruction exists in participants not exposed to any treatment. The sensation of nasal obstruction may be due to the amalgamation of many different nasal sensations. Improved methods for measuring nasal sensations are required to further investigate the relationship between objective and subjective measures of nasal obstruction. In a recent study it was shown that the subjective sensation of nasal patency increased as the nasal passages became objectively more obstructed in patients who received a placebo compared to those who received an oral decongestant. This paradoxical response may be explained as a placebo effect, i.e. patients who received a placebo may have expected to feel less obstructed. The aim of the present study was to investigate this interesting paradox by determining objective and subjective measures of nasal obstruction over time in participants not exposed to any treatment. A total of 60 healthy participants with common cold were recruited. Objective and subjective measures of nasal obstruction were recorded at baseline and at 1 and 2 h using posterior rhinomanometry and a visual analogue scale. Objective measures demonstrated an increase in nasal obstruction over time for both nasal passages considered together and for individual nasal passages. Subjective measures demonstrated a sensation of decreased nasal obstruction over time for both nasal passages considered together and for individual nasal passages.

Nasal obstruction is considered to be a potential etiological factor in sleep-disordered breathing. However, a significant correlation between nasal measurements and obstructive sleep apnea has not been demonstrated so far. The aim of this study was to investigate the relationships between nasal resistance, nasal volumes and selected sleep parameters using nasal measurements performed in both seated and supine positions. We also investigated whether snoring patients in our clinical sample showed increased positional or decongestive nasal mucosal changes. Forty-one snoring men on a waiting list for correction of nasal obstruction underwent polysomnography, anterior rhinomanometry and acoustic rhinometry. Nineteen non-snoring control subjects were also recruited. Nasal measurements were performed in a seated position, after lying down in a supine position and, after decongestion of nasal mucosa, in a seated position again. In the overall patient group, nasal volume at a distance 2-4 cm from the nares in the supine position correlated inversely with apnea-hypopnea index (AHI) (r = -0.32, p patients, total nasal resistance measured in a supine position correlated with AHI (r = 0.50, p position and sleep parameters. Postural or decongestive changes in nasal measurements were not increased in snoring patients compared with control subjects. The relationship found between nasal measurements and sleep parameters suggests that nasal obstruction does augment airway collapse.

Residual sleepiness after continuous positive airway pressure (CPAP) is a critical problem in some patients with obstructive sleep apnea syndrome (OSAS). However, nasal surgery is likely to reduce daytime sleepiness and feelings of unrefreshed sleep. The aim of this study is to clarify the effects of nasal surgery and CPAP on daytime sleepiness. This is a retrospective and matched-case control study. The participants were consecutive 40 patients with OSAS who underwent nasal surgery (Surgery group) and 40 matched patients who were treated with CPAP (CPAP group). In the Surgery group, although the nasal surgery did not decrease either apnea or hypopnea, it improved oxygenation, the quality of sleep. In the CPAP Group, the CPAP treatment reduced apnea and hypopnea, and improved oxygenation, quality of sleep. The degree of relief from daytime sleepiness was different between the two groups. The improvement of Epworth Sleepiness Scale was more significant in the Surgery Group than those in the CPAP Group (Surgery from 11.0 to 5.1, CPAP from 10.0 to 6.2). These findings suggest that the results of the nasal surgery is more satisfactory for some patients with OSAS than CPAP on daytime sleepiness.

The pronounced inspiratory efforts following UAO lead to excessive negative inspiratory pressure, which may cause acute pulmonary edema. Early recognition and prompt treatment of NPPE is necessary to prevent patient morbidity and mortality. In addition, the physician should carefully manage the patient who has risk factors of UAO to prevent this situation.

Rhinoplasty surgeons are aware that the nasal profile differs according to body position, namely, the erect position in the consultation room vs the supine position on the operating table. It is not clear whether this difference is caused by an optical illusion or skin laxity due to positional change. To evaluate anthropometric measurements of the nose with different body positions and determine whether the supine position affects the nasal profile. In this retrospective study, 103 patients who underwent primary rhinoplasty were enrolled. Preoperatively, all patients underwent lateral cephalography in the erect position, and facial computed tomography (CT), in the supine position. We measured four nasal anthropometric parameters (the nasofrontal, nasolabial, and nasomental angles, and Simon's ratio) on lateral cephalograms and facial CT images, and compared these parameters between the two body positions. The nasofrontal angle was greater on facial CT than on cephalograms (P sex, or body mass index (P > 0.05 each). We found no significant difference (P > 0.05) between the two positions in the nasolabial angle, nasomental angle, or Simon's ratio. The supine position does affect the nasal profile, especially in the radix area. Surgeons need to consider this difference in patients undergoing rhinoplasty. 2. © 2017 The American Society for Aesthetic Plastic Surgery, Inc. Reprints and permission: journals.permissions@oup.com

Face mask ventilation of the edentulous patient is often difficult as ineffective seating of the standard mask to the face prevents attainment of an adequate air seal. The efficacy of nasal ventilation in edentulous patients has been cited in case reports but has never been investigated. Consecutive edentulous adult patients scheduled for surgery under general anesthesia with endotracheal intubation, during a 17-month period, were prospectively evaluated. After induction of anesthesia and administration of neuromuscular blocker, lungs were ventilated with a standard anatomical face mask of appropriate size, using a volume controlled anesthesia ventilator with tidal volume set at 10 ml/kg. In case of inadequate ventilation, the mask position was adjusted to achieve best-fit. Inspired and expired tidal volumes were measured. Thereafter, the face mask was replaced by a nasal mask and after achieving best-fit, the inspired and expired tidal volumes were recorded. The difference in expired tidal volumes and airway pressures at best-fit with the use of the two masks and number of patients with inadequate ventilation with use of the masks were statistically analyzed. A total of 79 edentulous patients were recruited for the study. The difference in expiratory tidal volumes with the use of the two masks at best-fit was statistically significant (P = 0.0017). Despite the best-fit mask placement, adequacy of ventilation could not be achieved in 24.1% patients during face mask ventilation, and 12.7% patients during nasal mask ventilation and the difference was statistically significant. Nasal mask ventilation is more efficient than standard face mask ventilation in edentulous patients.

Objective Several types of nasal packs are used postoperatively in septoplasty. In this study, we compared two commonly used nasal packing materials, the intranasal septal splint with airway and Merocel tampon, in terms of pain, bleeding, nasal obstruction, eating difficulties, discomfort in sleep, and pain and bleeding during removal of packing in the early period. Methods The study group included 60 patients undergoing septoplasty. Patients were divided into two groups (n=30 in each group). An intranasal splint with airway was used for the patients in the first group after septoplasty, while Merocel nasal packing was used for the second group. Patients were investigated in terms of seven different factors - pain, bleeding while the tampon was in place, nasal obstruction, eating difficulties, night sleep, pain during removal of the nasal packing, and bleeding after removal of packing. Results There was no statistically significant difference between the groups in terms of pain 24 hours after operation (p=0.05), while visual analog scale (VAS) scores for nasal obstruction, night sleep, eating difficulties, and pain during packing removal were lower in the nasal splint group with a statistically significant difference (p<0.05). There was no statistically significant difference between the groups in terms of postoperative bleeding (p=0.23). Significantly less bleeding occurred during removal of the packing in the nasal splint group (p<0.05). Conclusion Our study indicates that the nasal splint was more comfortable and effective in terms of causing lesser bleeding and pain during removal of packing. PMID:29392071

Although several reports have shown that proton beam therapy (PBT) offers promise for patients with skull base cancer, little is known about the frequency of late toxicity in clinical practice when PBT is used for these patients. Here, we conducted a retrospective analysis to clarify the late toxicity profile of PBT in patients with malignancies of the nasal cavity, para-nasal sinuses, or involving the skull base. Entry to this retrospective study was restricted to patients with (1) malignant tumors of the nasal cavity, para-nasal sinuses, or involving the skull base; (2) definitive or postoperative PBT (>50 GyE) from January 1999 through December 2008; and (3) more than 1 year of follow-up. Late toxicities were graded according to the common terminology criteria for adverse events v4.0 (CTCAE v4.0). From January 1999 through December 2008, 90 patients satisfied all criteria. Median observation period was 57.5 months (range, 12.4-162.7 months), median time to onset of grade 2 or greater late toxicity except cataract was 39.2 months (range, 2.7-99.8 months), and 3 patients had toxicities that occurred more than 5 years after PBT. Grade 3 late toxicities occurred in 17 patients (19%), with 19 events, and grade 4 late toxicities in 6 patients (7%), with 6 events (encephalomyelitis infection 2, optic nerve disorder 4). In conclusion, the late toxicity profile of PBT in patients with malignancy involving the nasal cavity, para-nasal sinuses, or skull base malignancy was partly clarified. Because late toxicity can still occur at 5 years after treatment, long-term follow-up is necessary. (author)

The ability of respiratory mucosal surfaces to eliminate foreign particles and pathogens and to keep mucosal surfaces moist and fresh depends on mucociliary activity. Chronic renal failure (CRF) is an irreversible medical condition that may result in important extrarenal systemic consequences, such as cardiovascular, metabolic, and respiratory system abnormalities. Although there are studies describing nasal manifestations of CRF, data are lacking concerning the effects of the condition on nasal mucosa. The goal of the current study was to evaluate nasal mucociliary clearance (NMC) time in patients with CRF. This prospective cohort study conducted in a tertiary referral center included 32 non-diabetic end-stage CRF patients and 30 control individuals. The control group consisted of voluntary participants who had been referred to our clinic for symptoms other than rhinological diseases. The mean NMC times in CRF patients and control individuals were 12.51 ± 3.74 min (range 7-22 min) and 8.97 ± 1.83 min (range 6-13 min), respectively. The mean NMC time in patients with CRF was significantly longer than that in control individuals (p < 0.001). Clinicians must keep in mind that NMC time in CRF patients is prolonged and must follow-up these patients more closely for sinonasal and middle ear infections.

To examine rates of otolaryngology intervention in children presenting to our emergency department with nasal foreign bodies, factors associated with otolaryngology involvement, rates of complications, and details on nasal button battery exposure. All patients presenting with a nasal foreign body to Children's Hospital Colorado from 2007 to 2012 were identified. Factors leading to referral to otolaryngology and operative intervention were examined, as well as complications. 102 patients were included. 36 (35%) patients were referred to the otolaryngology clinic, of which 58.9% required operating room intervention. 66 (64.7%) children had their nasal foreign bodies removed in the emergency room, however 30 (45%) of these were removed by an otolaryngology resident or attending physician. Overall, 64.7% of nasal foreign bodies required removal by otolaryngology. Of the 15 objects removed in the operating room, six were button batteries. No septal perforations occurred as a result of nasal button battery exposure. Multivariable logistic regression showed two significant predictors of OR removal: age and disc shaped objects. While emergency department providers are comfortable attempting removal of nasal foreign bodies, there was a high rate of otolaryngology intervention. Based on this data, there is a need to educate emergency room providers on nasal anatomy and techniques for nasal foreign body removal. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

To determine whether the presence of nasal flaring is a clinical sign of respiratory acidosis in patients attending emergency departments for acute dyspnea. Single-center, prospective, observational study of patients aged over 15 requiring urgent attention for dyspnea, classified as level II or III according to the Andorran Triage Program and who underwent arterial blood gas test on arrival at the emergency department. The presence of nasal flaring was evaluated by two observers. Demographic and clinical variables, signs of respiratory difficulty, vital signs, arterial blood gases and clinical outcome (hospitalization and mortality) were recorded. Bivariate and multivariate analyses were performed using logistic regression models. The sample comprised 212 patients, mean age 78years (SD=12.8), of whom 49.5% were women. Acidosis was recorded in 21.2%. Factors significantly associated with the presence of acidosis in the bivariate analysis were the need for pre-hospital medical care, triage level II, signs of respiratory distress, presence of nasal flaring, poor oxygenation, hypercapnia, low bicarbonates and greater need for noninvasive ventilation. Nasal flaring had a positive likelihood ratio for acidosis of 4.6 (95% CI 2.9-7.4). In the multivariate analysis, triage level II (aOR 5.16; 95% CI: 1.91 to 13.98), the need for oxygen therapy (aOR 2.60; 95% CI: 1.13-5.96) and presence of nasal flaring (aOR 6.32; 95% CI: 2.78-14.41) were maintained as factors independently associated with acidosis. Nasal flaring is a clinical sign of severity in patients requiring urgent care for acute dyspnea, which has a strong association with acidosis and hypercapnia. Copyright © 2016 Elsevier Inc.

Transverse nasal groove is a condition of cosmetic concern which awaits due recognition and has been widely described as a shallow groove that extends transversely over the dorsum of nose. However, we observed variations in the clinical presentations of this entity, hitherto undescribed in literature. We conducted a clinicoepidemiological study of transverse nasal lesions in patients attending our outpatient department. We conducted a prospective observational study. We screened all patients attending our out-patient department for presence of transverse nasal lesions, signs of any dermatosis and associated other skin conditions. One hundred patients were recruited in the study. Females (80%) predominated over males. Most patients were of 15-45 years age group (70%). Majority of the transverse nasal lesions were classical transverse nasal groove (39%) and others included transverse nasal line (28%), strip (28%), ridge (4%) and loop (1%). Seborrhoeic diathesis was the most common condition associated with transverse nasal lesion. Occurrence of transverse nasal line, strip, ridge and loop, in addition to classical transverse nasal groove implies that latter is actually a subset of transverse nasal lesions. Common association of this entity with seborrheic dermatitis, seborrhea and dandruff raises a possibility of whether transverse nasal lesion is a manifestation of seborrheic diathesis.

The correlation between subjective and objective outcomes of nasal obstruction is still a matter of controversy. The aim of this study was to determine the minimal level of side difference in nasal airway resistance (NAR measured by Broms'v(2)) between the two nasal cavities, which could be discerned subjectively by the patient on a visual analogue scale (VAS). Nasal airway resistance was calculated from rhinomanometric measurements of nasal airflow and transnasal pressure after decongestion of the nasal mucosa. A retrospective study. ENT department, Vaxjo Central Hospital, Sweden. We studied 1000 active anterior rhinomanometries from patients with nasal obstructions. We compared the side difference of nasal airway resistance with the side difference of VAS estimated immediately prior to the rhinomanometry. Each measurement was performed after nasal decongestion. When the difference in nasal airway resistance between the two nasal cavities was larger than 20° (Broms'v(2)) or R(2) > 0.36 Pa/cm(3) /s, we found a significant correlation between side differences of the objective measurement and the subjective assessment (VAS). With a nasal airway resistance side difference over 20°, an additional 20° difference corresponded to a 0.9 centimetre average VAS change. The more obstructed side of the nose could be determined by VAS in 823 (82.3%) of 1000 patients. Yet, 177 (17.7%) patients had a paradoxical sensation of nasal obstruction with the low resistance side of the nose experienced as the most congested side. A significant correlation between the side differences of nasal airway resistance and VAS can serve as a supplement to rhinoscopy in decisions about nasal surgery. This study also showed that in 17.7% of patients, there was a negative correlation between subjective and objective evaluations of nasal airway resistance. But in this group, the nasal airway resistance side difference was mostly under 20°. © 2011 Blackwell Publishing Ltd.

A combination study of cerebrospinal fluid scintigraphy and nasal pledget counts was performed using 37 MBq of {sup 111}In-DTPA in 12 patients with suspected rhinorrhea. A pledget was inserted and dwelled in each nasal cavity for 6 hours, with the patient prone during at least 30 minutes. A total of 18 studies was implemented and nasal pledget counting method successfully diagnosed all of CSF rhinorrhea. Diagnosis was possible when pledget counts were greater than 1 kcpm. In patients with persistent, intermittent and occult/no nasal discharge, rhinorrhea was found in 100% (5/5), 60% (3/5), 25% (2/8), respectively. Two cases only exhibited positive scintigraphy. MRI or CT cisternography should be first performed in patients with persistent discharge, but in patients with intermittent/occult discharge pledget counting method might take priority of other diagnostic modalities. In conclusion, nasal pledget counting method is a simple and useful tool for detecting rhinorrhea. (author)

Perceiving nasal patency through mucosal cooling rather than air temperature or nasal resistance.

Directory of Open Access Journals (Sweden)

Kai Zhao

Full Text Available Adequate perception of nasal airflow (i.e., nasal patency is an important consideration for patients with nasal sinus diseases. The perception of a lack of nasal patency becomes the primary symptom that drives these patients to seek medical treatment. However, clinical assessment of nasal patency remains a challenge because we lack objective measurements that correlate well with what patients perceive. The current study examined factors that may influence perceived patency, including air temperature, humidity, mucosal cooling, nasal resistance, and trigeminal sensitivity. Forty-four healthy subjects rated nasal patency while sampling air from three facial exposure boxes that were ventilated with untreated room air, cold air, and dry air, respectively. In all conditions, air temperature and relative humidity inside each box were recorded with sensors connected to a computer. Nasal resistance and minimum airway cross-sectional area (MCA were measured using rhinomanometry and acoustic rhinometry, respectively. General trigeminal sensitivity was assessed through lateralization thresholds to butanol. No significant correlation was found between perceived patency and nasal resistance or MCA. In contrast, air temperature, humidity, and butanol threshold combined significantly contributed to the ratings of patency, with mucosal cooling (heat loss being the most heavily weighted predictor. Air humidity significantly influences perceived patency, suggesting that mucosal cooling rather than air temperature alone provides the trigeminal sensation that results in perception of patency. The dynamic cooling between the airstream and the mucosal wall may be quantified experimentally or computationally and could potentially lead to a new clinical evaluation tool.

Does Post Septoplasty Nasal Packing Reduce Complications?

Directory of Open Access Journals (Sweden)

Bijan Naghibzadeh

2011-01-01

Full Text Available The main issues in nasal surgery are to stabilize the nose in the good position after surgery and preserve the cartilages and bones in the favorable situation and reduce the risk of deviation recurrence. Also it is necessary to avoid the synechia formation, nasal valve narrowing, hematoma and bleeding. Due to the above mentioned problems and in order to solve and minimize them nasal packing, nasal splint and nasal mold have been advised. Patients for whom the nasal packing used may faced to some problems like naso-pulmonary reflex, intractable pain, sleep disorder, post operation infection and very dangerous complication like toxic shock syndrome. We have two groups of patients and three surgeons (one of the surgeons used post operative nasal packing in his patients and the two others surgeons did not.Complications and morbidities were compared in these two groups. Comparing the two groups showed that the rate of complication and morbidities between these two groups were same and the differences were not valuable, except the pain and discomfort post operatively and at the time of its removal. Nasal packing has several risks for the patients while its effects are not studied. Septoplasty can be safely performed without postoperative nasal packing. Nasal packing had no main findings that compensated its usage. Septal suture is one of the procedures that can be used as alternative method to nasal packing. Therefore the nasal packing after septoplasty should be reserved for the patients with increased risk of bleeding.

The relationship between airflow patterns in the nasal cavity and nasal function is poorly understood. This paper reports an experimental study of the interplay between symptoms and airflow patterns in a patient affected with atrophic rhinitis. This pathology is characterized by mucosal dryness, fetor, progressive atrophy of anatomical structures, a spacious nasal cavity, and a paradoxical sensation of nasal congestion. A physical replica of the patient's nasal geometry was made and particle image velocimetry (PIV) was used to visualize and measure the flow field. The nasal replica was based on computed tomography (CT) scans of the patient and was built in three steps: three-dimensional reconstruction of the CT scans; rapid prototyping of a cast; and sacrificial use of the cast to form a model of the nasal passage in clear silicone. Flow patterns were measured by running a water-glycerol mixture through the replica and evaluating the displacement of particles dispersed in the liquid using PIV. The water-glycerol flow rate used corresponded to an air flow rate representative of a human breathing at rest. The trajectory of the flow observed in the left passage of the nose (more affected by atrophic rhinitis) differed markedly from what is considered normal, and was consistent with patterns of epithelial damage observed in cases of the condition. The data are also useful for validation of computational fluid dynamics predictions.

Reduced nasal nitric oxide production in cystic fibrosis patients with elevated systemic inflammation markers.

Directory of Open Access Journals (Sweden)

Ruth K Michl

Full Text Available BACKGROUND: Nitric oxide (NO is produced within the respiratory tract and can be detected in exhaled bronchial and nasal air. The concentration varies in specific diseases, being elevated in patients with asthma and bronchiectasis, but decreased in primary ciliary dyskinesia. In cystic fibrosis (CF, conflicting data exist on NO levels, which are reported unexplained as either decreased or normal. Functionally, NO production in the paranasal sinuses is considered as a location-specific first-line defence mechanism. The aim of this study was to investigate the correlation between upper and lower airway NO levels and blood inflammatory parameters, CF-pathogen colonisation, and clinical data. METHODS AND FINDINGS: Nasal and bronchial NO concentrations from 57 CF patients were determined using an electrochemical analyser and correlated to pathogen colonisation of the upper and lower airways which were microbiologically assessed from nasal lavage and sputum samples. Statistical analyses were performed with respect to clinical parameters (lung function, BMI, laboratory findings (CRP, leucocytes, total-IgG, fibrinogen, and anti-inflammatory and antibiotic therapy. There were significant correlations between nasal and bronchial NO levels (rho = 0.48, p<0.001, but no correlation between NO levels and specific pathogen colonisation. In patients receiving azithromycin, significantly reduced bronchial NO and a tendency to reduced nasal NO could be found. Interestingly, a significant inverse correlation of nasal NO to CRP (rho = -0.28, p = 0.04 and to leucocytes (rho = -0.41, p = 0.003 was observed. In contrast, bronchial NO levels showed no correlation to clinical or inflammatory parameters. CONCLUSION: Given that NO in the paranasal sinuses is part of the first-line defence mechanism against pathogens, our finding of reduced nasal NO in CF patients with elevated systemic inflammatory markers indicates impaired upper airway defence.

2017-12-01

Full Text Available Introduction Congenital midline nasal masses include nasal dermoids, gliomas, encephaloceles. Although rare, these disorders are clinically important because of their potential for connection to the central nervous system. Preoperative knowledge of an intracranial connection is a necessity to allow for neurosurgical consultation and possible planning for craniotomy. This study discusses the clinical presentation of congenital midline nasal mass and the role of imaging modalities like CT scan and MRI in diagnosis and the surgical management. Materials and Methods  This prospective study is carried from March 2014 to March 2016, during which 4 cases presented to the Otorhinolaryngology department. Pre-operative evaluation of the patients included endoscopic evaluation along with haematological investigations, CT Scan and MRI. The masses were removed with nasal endoscopic sinus surgery or by external approaches and neurosurgical intervention. Result The age of the patients ranged from 3 years to 25 years. Three of them were male and one female. There was one case of nasoethmoidal encephalocele and the other three were dermoids (intranasal dermoid cyst, nasal dermoid cyst and nasal dermoid sinus cyst. Conclusion Congenital midline nasal masses are rare. These disorders are clinically important because of their intracranial connection which require proper evaluation with radiological imaging like CT scan and/or MRI before FNAC and any surgical intervention.

Full Text Available Introduction. Juvenile nasal angiofibroma (JNA is an aggressively expanding fibro-vascular benign tumor, which occurs in male adolescents. Surgical management of JNA is considered as one of the most difficult in rhinology, because it very often has accompanied with profuse, streaming bleeding. Endovascular embolization has successfully used for reducing the operative blood loss since 2000th. Nevertheless, there is no consensus in the literature about its expediently using because of complications, which may occur.Objective is to evaluate the effectiveness of selective angiography and endovascular embolization in reducing bleeding when removal of JNA of different stages.Materials and methods. In the N.N. Burdenko National Medical Research Center of Neurosurgery 134 patients with JNA had been treated surgically.Results. 110 patients with JNA, who underwent embolization, managed to perform total, subtotal or partial devascularization of the tumor. Total devascularization was achieved in JNA blood supply variant only from the external carotid artery (ECA system from 1 or 2 sides  (in primary patients or in patients who had not previously been embolized (n = 39; subtotal devascularization, if the blood supply was carried out from the ECA system, internal carotid artery (ICA on the 1 side (n = 52 and partial, if there was blood supply from the ECA and significant from the ICA system from 2 sides (in patients with relapse after previous embolization with microspirals or the ECA ligations from 1 or 2 sides, as well as with giant JNA (n = 19. Since the vast majority of patients admitted to our clinic were previously operated on, and JNA blood supply in relapses was more pronounced, we performed the comparison of the degree of tumor devascularization depending on its blood supply in primary patients and patients with relapse. It turned out, as could be expected, that with the primary JNA often managed  to execute a total devascularization than with JNA

Background Nasal closure has been shown to effectively manage severe epistaxis refractory to other treatments in patients with hereditary hemorrhagic telangiectasia (HHT). The nasal closure procedure may be underutilized due to its surgical complexity and flap breakdown. Methods Retrospective review of thirteen HHT patients treated for severe epistaxis with nasal closure between 2005 and 2013. Operating room (OR) time, need for revision surgery, pre- and post-procedure epistaxis severity score (ESS), complete blood count values, and Glasgow Benefit Inventory (GBI) questionnaire results were collected for each patient. The technique is described. We characterize a typical nasal closure patient and compare outcomes based on our experience with the traditional three-flap closure and a simplified two-flap nasal closure procedure. Results The average candidate for nasal closure in this series had an ESS of 7.88, Hgb of 8.3 g/dL, and received multiple transfusions, iron therapy, and cautery/coagulation procedures. Average ESS subsequent to nasal closure using the two flap method is 0.92 and mean GBI score is 56.3. Comparison of five patients who underwent the traditional three-flap nasal closure procedure and eight patients receiving the two flap nasal closure showed no significant difference in post-op ESS or GBI metrics. Mean operating room times of the traditional and simplified methods were 3.12 hours and 1.44 hours (p=0.0001). Mean time to first revision for eight nasal closure patients is 21.5 months. Conclusion In short-term follow-up, the two-flap procedure has shown comparable effectiveness with significantly reduced complexity and operative time compared to the traditional nasal closure method.

Full Text Available OBJECTIVE: To investigate the value of high-flow nasal cannula oxygen therapy after extubation in patients with acute respiratory failure. METHODS: A single-center, prospective, randomized, controlled pilot trial was conducted between January 2013 and December 2014. Sixty enrolled patients were randomized immediately after extubation into either a high-flow nasal cannula group (n=30 or an air entrainment mask group (n=30 at a fixed inspired oxygen fraction (40%. The success rate of oxygen therapy, respiratory and hemodynamic parameters and subjective discomfort (using a visual analogue scale were assessed at 24h after extubation. RESULTS: The two groups were comparable at extubation. A total of 46 patients were successfully treated including 27 patients in the high-flow nasal cannula group and 19 patients in the air entrainment mask group. Compared to the air entrainment mask group, the success rate of oxygen therapy and the partial pressure of arterial oxygen were significantly higher and the respiratory rate was lower in the high-flow nasal cannula group. In addition, less discomfort related to interface displacement and airway dryness was observed in the high-flow nasal cannula group than in the air entrainment mask group. CONCLUSIONS: At a fixed inspired oxygen fraction, the application of a high-flow nasal cannula after extubation achieves a higher success rate of oxygen therapy and less discomfort at 24h than an air entrainment mask in patients with acute respiratory failure.

The objective of this work was to explore the utility of axial computed tomography (CT) imaging to objectively define a narrow internal nasal valve, and compare those findings with clinical examination and patient complaint. Retrospective review from a single facial plastic surgery center. We reviewed 40 consecutive patients evaluated for either sinusitis or nasal airway obstruction for which a CT scan was obtained at a single radiology institution. Thirty-six complete office records were examined for the presence of clinical internal valve narrowing and complaints of nasal obstruction. In total, 72 internal nasal valves were analyzed using axial plane CT and measurements were compared to clinical findings and presence of airway obstruction. Measured valve areas for clinically normal internal nasal valves averaged 0.47 cm(2) vs 0.28 cm(2) for clinically narrow valves, a decrease of 40.4%. In unobstructed nasal airways the valve area averaged 0.51 cm(2) vs 0.38 cm(2) in obstructed airways, a difference of 25.5%. A radiographically measured valve area of <0.30 cm(2) suggests clinical narrowing with a sensitivity of 71.4%, specificity of 88.9%, positive predictive value of 62.5%, and negative predictive value of 92.3%. Using standard axial CT imaging we describe an objective method of radiographically evaluating the nasal valve, demonstrating strong correlation with physical examination and patient complaint. Additionally, radiographic valve areas can be used to screen for clinically narrow nasal valves with good sensitivity and specificity, providing a novel straightforward method for nasal valve assessment. © 2012 ARS-AAOA, LLC.

The traditional method of management of posterior epistaxis has been with anteroposterior nasal packing. Apart from the high failure rate of 26-50% reported in various series, nasal packing is associated with marked discomfort and several complications. In order to avoid nasal packing, we started doing endoscopic cauterization in cases of posterior epistaxis. A total of 23 patients with posterior epistaxis were subjected to nasal endoscopy with the intent to stop bleeding by cauterization of the bleeding vessel. Of these, in four cases unsuspected diagnosis was made. Of the remaining 19, in three patients, the bleeding point could not be localized accurately and these patients were managed by anteroposterior packing. The rest of the 16 patients were managed by endoscopic cauterization. In four patients, there was recurrence of bleeding within 24 h. In one of these, cauterization controlled the bleeding while in the rest nasal packing had to be resorted to. Thus, of the 23 patients of posterior epistaxis subjected to nasal endoscopy, we could avoid nasal packing in 17 (74%). To conclude, endoscopic nasal cauterization is recommended as the first line to treatment in all cases of posterior epistaxis. This will not only prevent the uncomfortable and potentially dangerous nasal packing but also help in finding the underlying pathology.

Ehen refractory to optimal medical treatment cardiogenic pulmonary edema requires mechanical ventilation as a last therapeutic resource. In recent years an increasing number of authors reported their experience in the management of acute or subacute respiratory failure with non-invasive mechanical ventilation by nasal mask. Encouraged by the first promising results reported in literature we experimented this new therapeutic tool in a first group of seven elderly patients (mean age: 76.57--range: 65-89); they all had been admitted for severe cardiogenic pulmonary edema unresponsive to maximal doses of the conventional drugs available for treating acute decompensated heart failure. The enrolled patients were treated with intermittent ventilation administered by nasal mask at selected values of inspiratory positive airway pressure (IPAP) that were comprised between 10 and 20 cm H2O. At the same time an expiratory positive airway pressure (EPAP) at values comprised between 3 and 8 cm H2O was applied. Ventilation was continued for variable periods of 3-24 hours until acceptable values of PaO2 and PaCO2 were obtained. The ventilation modality was spontaneous, spontaneous-time or timed depending on the patients' level of consciousness at starting time. A good short-term outcome was achieved in all the patients regardless of the ventilation modality applied. The main blood gas alteration was severe hypercapnia with acidosis in three patients, while the other four presented critical hypoxemia unresponsive to simple oxygen supply even if delivered by high-flow Venturi mask. Four of our seven patients were discharged from hospital in satisfactory haemodynamic conditions; the remaining three died during hospitalization from refractory heart failure. In this our preliminary experience the therapeutic approach with nasal positive pressure ventilation (NPPV) and EPAP proved to be very effective to improve the signs and symptoms of acute refractory cardiogenic pulmonary edema as

Objective : To identify factors related to quality of life (QoL) and satisfaction with nasal appearance among patients treated for unilateral cleft lip and palate (UCLP). Design : Cross-sectional population study with long-term follow-up. Patients/Settings : All patients with UCLP born between 1960 and 1987, treated at Uppsala University Hospital, were invited (n  =  109); 86 (79%) participated. Mean follow-up time was 35 years. Main Outcome Measures : Quality of life was measured with Short Form-36 (SF-36) and analyzed using mental and physical cluster scores (MCS and PCS). Nasal appearance was self-assessed with the "Satisfaction With Appearance" questionnaire and by panel judgment. Multivariate regression analyses explored endogenous factors (age, gender, infancy cleft width, nasal function, nasolabial appearance) and exogenous factors (marital status, number of children, education level, operation method, number of rhinoplasties performed). Results : A larger cleft width in infancy was associated with less satisfaction with nasal appearance as adults. A lower mental health QoL was associated with less satisfaction with nasal appearance. Despite female gender being linked to less satisfaction with nasal appearance, it was associated with higher mental health QoL. Higher resistance during nasal breathing was associated with lower physical health QoL. Conclusions : Gender and infant cleft width may affect QoL and satisfaction with nasal appearance among adults. They are potential predictive factors for satisfaction with nasal appearance and QoL during adulthood. The correlation of nasal function impairment and decreased physical health QoL underlines the importance of treatment of nasal symptoms in these patients.

Inferior turbinate (IT) hypertrophy and adenoid hypertrophy are both causes of pediatric nasal obstruction. The purpose of this survey was to study nasal obstruction evaluation and management among pediatric otolaryngologists with respect to IT and adenoid hypertrophy. A questionnaire with embedded clinical videos was sent electronically to American Society of Pediatric Otolaryngology members. A total of 435 questionnaires were sent, and 75 were completed. Respondents were presented with scenarios that involved a 7-year-old child with nasal obstruction unresponsive to medical therapy, and the respondents were asked to choose a surgical plan, either IT reduction, adenoidectomy, or combined IT reduction and adenoidectomy. Three questions described the extent of IT and adenoid obstruction in text form, although three questions included a video of the child's nasal endoscopy. In questions with perceived or stated IT hypertrophy, the respondents chose to perform IT reduction significantly more frequently when the perceived or stated adenoid hypertrophy was less severe (p < 0.0001 for video and p = 0.039 for written questions). The decision to perform IT reduction in children is inversely related to the extent of adenoid hypertrophy. Future studies on pediatric IT surgery should include objective descriptions of the IT and adenoid in study subjects.

Casiano, Roy R.

2012-01-01

Background: Benign lesions of the nasal cavity represent a diverse group of pathologies. Furthermore, each of these disorders may present differently in any given patient as pain and discomfort, epistaxis, headaches, vision changes, or nasal obstruction. Although these nasal masses are benign, many of them have a significant capacity for local tissue destruction and symptomatology secondary to this destruction. Advances in office-based endoscopic nasendoscopy have equipped the otolaryngologist with a safe, inexpensive, and rapid means of directly visualizing lesions within the nasal cavity and the initiation of appropriate treatment. Methods: The purpose of this study is to review the diagnosis, management, and controversies of many of the most common benign lesions of the nasal cavity encountered by the primary care physician or otolaryngologist. Results: This includes discussion of inverted papilloma (IP), juvenile angiofibroma, squamous papilloma, pyogenic granuloma, hereditary hemorrhagic telangiectasia, schwannoma, benign fibro-osseous lesions, and other benign lesions of the nasal cavity, with particular emphasis on IP and juvenile angiofibroma. Conclusion: A diverse array of benign lesions occur within the nasal cavity and paranasal cavities. Despite their inability to metastasize, many of these lesions have significant capability for local tissue destruction and recurrence. PMID:22487294

SEPTOPLASTY WITH AND WITHOUT NASAL PACKING: A COMPARATIVE STUDY

2016-05-01

Full Text Available Septoplasty is one of the most commonly performed surgeries in rhinology to relieve nasal obstruction of patients with distortion in the midline cartilage or septum of the nose to relieve nasal obstruction of patient and findings consistent with nasal endoscopy. The anterior nasal packing routinely done following septoplasty is usually conventional and not evidence based. The purpose of nasal packing is to obtain haemostasis, enhance opposition of septal flaps, avoid septal haematoma formation, close the dead space, avoid synechiae formation, provide support to septal cartilage and prevent its displacement. OBJECTIVE This study intends to evaluate the effects of nasal packing on surgical success and related complications in septoplasty. MATERIALS AND METHODS The present clinical prospective and randomised study was carried out on patients attending Otorhinolaryngology Department of Santhiram Medical College & General Hospital between March 2012 and March 2015. Patients undergoing septoplasty were randomised either to receive anterior nasal packing or to not receive nasal packing postoperatively. RESULTS Levels of pain experienced by patients with nasal packing postoperatively during the initial 24 hours postoperatively and during the removal of the pack were significantly more. Post-operative headache, epiphora, swallowing discomfort and sleep disturbance were more in patients with nasal packing and statistically (p.05. Septal haematoma, adhesions and local infections in both groups were statistically insignificant (p>.05. CONCLUSION Septoplasty enhances the standard of living of patients with septal deviation and nasal obstruction. Our study results suggest that nasal packing after septoplasty is not obligatory. Nasal packing causes considerably more pain and complications, and it should be reserved only for those who have bleeding predisposition.

Full Text Available In this prospective study, a quantitative determination of histamine and tryptase in nasal secretions after nasal phosphate buffered saline (PBS and allergen challenge was performed in 18 atopic patients who were compared with ten non-allergic healthy volunteers. The aim of the study was to determine the normal and pathological concentrations of these important mediators in nasal secretions. The second objective was to test the relevance of these two mast cell secreted mediators after nasal challenge. Results showed that the concentrations of tryptase in almost all samples were under the minimal detection limit (< 0.5 μU/g and only a sigrtificant increase of tryptase (median, 28 μU/g occurred immediately after nasal allergen challenge in the patient group. Histamine concentration significantly increased after every nasal PBS challenge (median, 69 ng/g after first PBS challenge and 165 ng/g after second PBS challenge in the control group, as well as in the patient group after both PBS (median, 69 ng/g and allergen (median, 214 ng/g challenge. On the other hand, a rapid onset of sneezing and increase in nasal airway resistance was experienced only in the patient group after nasal allergen challenge, but did not occur after PBS challenge even though the histamine concentrations significantly increased in both groups. This study suggests that tryptase is a more preferable marker than histamine in quantitative monitoring of mast cell activation especially during the early phase nasal allergic reaction.

Objective Rhinoplasty, a surgical procedure that alters the shape or appearance of the nose while preserving or enhancing the nasal airway, ranks among the most commonly performed cosmetic procedures in the United States, with >200,000 procedures reported in 2014. While it is difficult to calculate the exact economic burden incurred by rhinoplasty patients following surgery with or without complications, the average rhinoplasty procedure typically exceeds $4000. The costs incurred due to complications, infections, or revision surgery may include the cost of long-term antibiotics, hospitalization, or lost revenue from hours/days of missed work. The resultant psychological impact of rhinoplasty can also be significant. Furthermore, the health care burden from psychological pressures of nasal deformities/aesthetic shortcomings, surgical infections, surgical pain, side effects from antibiotics, and nasal packing materials must also be considered for these patients. Prior to this guideline, limited literature existed on standard care considerations for pre- and postsurgical management and for standard surgical practice to ensure optimal outcomes for patients undergoing rhinoplasty. The impetus for this guideline is to utilize current evidence-based medicine practices and data to build unanimity regarding the peri- and postoperative strategies to maximize patient safety and to optimize surgical results for patients. Purpose The primary purpose of this guideline is to provide evidence-based recommendations for clinicians who either perform rhinoplasty or are involved in the care of a rhinoplasty candidate, as well as to optimize patient care, promote effective diagnosis and therapy, and reduce harmful or unnecessary variations in care. The target audience is any clinician or individual, in any setting, involved in the management of these patients. The target patient population is all patients aged ≥15 years. The guideline is intended to focus on knowledge gaps, practice

Full Text Available The correction of cleft lip nasal deformity is challenging and there have been numerous methods described in the literature with little demonstrated technical superiority of one over another. The common clinical issues associated with cleft lip nasal deformity are its lack of symmetry, alar collapse on the affected side, obtuse nasal labial angle, short nasal length, loss of tip definition, and altered columella show among others. We carried out augmentation of cleft lip rhinoplasties with rib graft in 16 patients over the one-year study period. Each of these patients was reviewed and given questionnaire before and after surgery to evaluate their response on the outcome to the approach. Preoperatively, nasal asymmetry is the main complaint (14/16, 87.5% among our series of patients. Postoperatively, 12 (75% patients out of the 16 reported significant improvement in their nasal symmetry with the other four marginal. All patients reported excellent nasal projection postoperatively with good nasal tip definition. Our series of patients reported overall good satisfaction outcome and will recommend this procedure to other patients with cleft lip nasal deformity. In conclusion, augmentation of cleft lip rhinoplasty can be employed to achieve perceivable and satisfactory outcome in patients with cleft lip nasal deformity.

Following nasal hump removal during septorhinoplasty, the middle vault should be reconstructed to avoid functional and esthetic problems. Middle vault reconstruction, however, may result in widening of the middle vault and may need a camouflage graft to cover dorsal irregularities. To present the results of reconstructing the middle vault with a technique that covers the nasal dorsum with upper lateral cartilage, from the viewpoint of patient satisfaction. Retrospective study of patients who underwent septorhinoplasty that included nasal dorsum closure with upper lateral cartilage from December 1, 2014 to January 31, 2016. Those with postoperative follow-up of less than 3 months were excluded. The final study group included 39 patients. The same surgeon performed all septorhinoplasties. The dorsum was closed using an "upper lateral closing" technique that approximated upper lateral cartilages to each other over the septum. Postoperative patient satisfaction was determined using a visual analog scale and the rhinoplasty outcomes evaluation questionnaire. The questionnaire evaluates patient esthetic and functional satisfaction with the operated nose. High scores indicate improved esthetic results. No dorsal irregularities were seen at postoperative follow-up evaluation of the patients. For esthetic nasal appearance, the median visual analogue scale scores was 86%, and the mean for the questionnaire was 77.03%. The natural dome-shaped anatomy of the nasal dorsum was achieved by approximating the upper lateral cartilages to each other. Closing the dorsum with this technique also covers any dorsal irregularities and results in a smooth dorsum. Patients expressed satisfaction with the esthetic and functional aspects of the smooth, attractive nasal dorsum.

Full Text Available Nasal vestibular furunculosis is a common bacterial skin infection among the general population mostly affecting adults and children.It is characterized by acute localized infection of hair follicle in the skin lining of the nasal vestibule caused by Staphylococcus aureus. Immunodeficiency also plays an important role in recurrent skin and soft tissue infections (SSTI including Nasal furunculosis. Though, the lesion is small, it is extremely painful and tender. Treatment is mostly conservative which consists of warm compresses, analgesics to relieve pain, topical and systemic antibiotics directed against staphylococcus. With rapidly increasing resistance to antibacterial agents, management of these bacterial infections is becoming increasingly difficult. In Ayurveda, it can be correlated with Nāsāruṇaśikhā (Nasal furunculosis. Morphologically, it appears like pīḍikā (Furuncle which is characterized by Rāgayuktaśotha (inflammation with reddening. Jalaukāvacaraṇa (Leech therapy is one of the ancient and important parasurgical procedures described in Ayurveda for treatment of various diseases. In this case, a leech has been applied at the affected area. After leech treatment, throbbing pain was reduced in its intensity followed by gradual reduction in swelling and reddening in two days.This case suggests the utility of leech application in Nasal vestibular furunculosis.

Allergic rhinitis is usually treated with oral antihistamines or nasal steroids. Topically active nasal antihistamine is a new treatment modality for allergic rhinitis. The efficacy in comparison to well established topical treatment alternatives is not fully known. To compare the efficacy of intranasally administered azelastine to budesonide, at their respectively recommended dosage, on the symptoms of perennial rhinitis patients. A placebo-controlled, randomized, parallel group study was conducted to compare the efficacy and tolerability of intranasal budesonide aqueous suspension (256 microg once daily) with azelastine hydrochloride nasal spray (280 microg twice daily (560 microg/day)) and with placebo in the treatment of perennial allergic rhinitis. The 195 patients (with at least a 2-year history of perennial allergic rhinitis) recorded individual nasal symptom scores, the degree of symptom control achieved and any adverse events experienced over a 2-week baseline period and a 6-week treatment period. Following treatment, the reductions in mean combined and individual nasal symptom scores from baseline values were significantly greater in the budesonide group compared with the placebo group (P < .0001 for all variables except runny nose P = .01). In patients treated with budesonide, there were also significantly larger reductions from baseline values in combined nasal symptom scores (P < .01) and in scores for all individual nasal symptoms (P < or = .05) compared with those treated with azelastine. The reductions from baseline in both combined and individual nasal symptom scores did not differ between azelastine and placebo. The study medications were well tolerated, producing no unexpected or serious treatment-related adverse events. A once-daily dose of 256 microg of intranasal budesonide aqueous suspension is significantly more effective at relieving the symptoms of perennial allergic rhinitis compared with a twice daily dose of 280 microg of azelastine

The aim of this study was to evaluate changes in nasal and oropharyngeal flora in patients with acne during treatments with tetracycline and isotretinoin. Swab specimens were taken from the right and left nasal cavities and oropharynx of 55 patients with acne and 20 healthy volunteers who were admitted to the dermatology department (Etlik Educational and Research Hospital, Ankara, Turkey) before the administration of treatment and in the third month of treatment. Study participants were divided into four groups as follows: patients with acne on topical treatment only, systemic isotretinoin, and systemic tetracycline, and the control group. Of 55 patients with acne, 18 were male and 37 were female. The mean age of the patients and the control group was 22.21 ± 4.22 and 21.95 ± 7.64, respectively. Staphylococcus aureus was isolated from the nasal flora of five patients, normal flora was suppressed in the oropharyngeal cultures of seven patients, and normal flora grew in the cultures of the other 20 patients who were on tetracycline treatment. On the other hand, normal flora grew in the nasal and oropharyngeal cultures of all the patients who were on isotretinoin treatment. Treatment options and follow-up procedures for acne vulgaris may lead to the development of bacterial resistance and damage to flora. In particular, systemic tetracycline treatment leads to changes in flora of the nose and throat in patients with acne with an increased carriage of S. aureus. Therefore, careful attention should be paid to the duration of tetracycline treatment in order to not increase the risk of disturbance of microbial flora. © 2014 The International Society of Dermatology.

The sinonasal involvement is one of the most common manifestations in cystic fibrosis. Data show a high incidence of chronic rhino sinusitis in these patients. Although it has been found radiographic opacification of the sinus in more than 90% of cases, few are symptomatic. So that, it is difficult to recognize nasossinusal disease in patients with cystic fibrosis. Questionnaire, nasal endoscopy and CT-scan are very important methods in this approach. Aim: to evaluate the diagnosis of chronic rhino sinusitis in patients with cystic fibrosis by anamnesis, nasal endoscopy and CT-scan and compare those results.Study Design: Clinical prospective. Material and method: evaluation of 34 patients - older than 6 years and with a confirmed diagnoses of cystic fibrosis - by anamnesis (questionnaire), nasal endoscopy (score Lund-Kennedy) and CT-scan (score Lund-Mackay). Results: chronic rhino sinusitis was confirmed in: 20,58% of cases by the questionnaire, 73,52% of the cases by the nasal endoscopy and in 93,54% of the cases by the CT-scan. The results showed significant differences. The correlation between nasal endoscopy score (Lund-Kennedy score) and CT-scan score (Lund-Mackay score) was statistically significant. Conclusion: the diagnosis of chronic rhino sinusitis was statistically different between the three methods. It was higher in imaging analysis and lower in questionnaire. The nasal endoscopy is an excellent method to evaluate nasossinusal disease in cystic fibrosis. (author)

The aim of this study was to investigate the effect of topically applied ocular anesthetic proparacaine on conjunctival and nasal bacterial mucosal flora in patients with dry eye disease. A Schirmer test was done with (group 1) and without (group 2) topical anesthetic proparacaine to 40 patients in each group. Conjunctival and nasal cultures were obtained before and 10 min after performing the Schirmer test. The bacterial culture results and the isolated bacteria were recorded in two groups. Patients' mean age was 62 years (70 female, 10 male). Before the application of topical anesthetic, 50 (62.5%) and 62 (77.5%) had positive conjunctival and nasal culture, respectively, with the most commonly isolated organism being coagulase-negative Staphylococcus in each group. In group 1 the conjunctival bacterial culture positivity rate decreased from 26 (65%) to six (15%) eyes ( p 0.05). For the nasal cultures, the bacterial culture positivity rate decreased from 80% to 20% and from 75% to 65% in groups 1 ( p 0.05), respectively. Topical ocular anesthetic proparacaine has antibacterial activity in both conjunctival and nasal flora in patients with dry eye disease.

Evidence-based management of nasal polyposis by intranasal corticosteroids: from the cause to the clinic.

Bachert, Claus

2011-01-01

Nasal polyposis is an inflammatory disorder involving the mucosa of the nose and paranasal sinuses and affecting approximately 2-4% of the general population. A literature search of Medline and Embase was conducted to obtain an overview of the epidemiology, pathophysiology, and current treatment of nasal polyposis, focusing on evidence-based efficacy of intranasal corticosteroids (INSs) as primary and postoperative therapy. Recent research on INSs in nasal polyp treatment, along with notable historic findings, was reviewed. Nasal polyps are mostly characterized by eosinophil infiltration, a complex inflammation of nasal mucosa, and possibly production of polyclonal IgE. Current treatment modalities include INSs, oral corticosteroids, and surgery; surgery is generally limited to those with an insufficient response to medical treatment. Because of their effects on eosinophil-dominated inflammation, INSs and oral corticosteroids are the primary medical treatment strategies. The very low (≤1%) systemic bioavailability of newer INSs minimizes the systemic adverse effects seen with oral corticosteroids. Based on randomized, controlled trials, guidelines recommend INSs as first-line therapy for nasal polyps and for care after polypectomy. Clinical data suggest INSs are effective in reducing polyp size and relieving nasal symptoms. INS treatment has also reduced nasal polyp recurrence in patients undergoing functional endoscopic sinus surgery. Treatment with these mainstay options has been found to improve quality of life, which, along with symptom improvement, is a key factor in disease treatment. Copyright © 2011 S. Karger AG, Basel.

The purposes of this study were to derive nasalance norms for monolingual Greek speakers, to examine nasalance scores as a function of gender and to draw cross-linguistic comparisons based on normative data. Participants read aloud a corpus of linguistic material, consisting of (1) a nasal text, an oral text and a balanced text; (2) a set of nasal sentences and four sets of oral sentences and (3) repetitions of each of 12 syllable types (8 oral and 4 nasal). The last two sets of material corpus were based on an adaptation of the Simplified Nasometric Assessment Procedures Test (SNAP test) test ( MacKay and Kummer, 1994 ) in Greek, called the G-SNAP test. Eighty monolingual healthy young adult speakers of Greek, 40 males (mean age = 21 years) and 40 females (mean age = 20.5 years), with normal hearing and speech characteristics and unremarkable history were included in the study. The Nasometer (model 6200-3) was used to derive nasalance scores. Mean normative nasalance for spoken Greek was 25.50%, based on the G-oronasal text (with 8.6% nasals). Nasalance scores did not differ significantly with respect to gender. Finally, spoken Greek consistently yielded lower nasalance scores than other languages examined in past work. The aforementioned normative data on nasalance of young adult speakers of Greek are valid across gender and have direct clinical utility as they provide valuable reference information for the diagnosis and management of Greek adults with resonance disorders caused by velar dysfunction.

Patients with dentofacial deformities may benefit from orthognathic surgery in the maxilla. Maxillary osteotomy may include procedures in the bone, cartilaginous, and soft tissues of the nose, leading to shape alterations. To evaluate the anatomic alterations of the nasal region in patients undergoing a Le Fort I osteotomy for advancement or superior impaction. This is a clinical prospective study. Twenty-one patients were evaluated during the pre- and postoperative periods. The positioning of the nasal tip and the modification of the nasal base were evaluated. The results showed that the nasal tip was superiorly positioned in 85% of the cases, advanced in 80%, rotated in 80%, and there was a wide nasal base in 95%, resulting in esthetic improvement. Surgeries of maxillary advancement and superior reposition tend to cause elevation and advancement of the nasal tip, as well as enlargement of the nasal base.

Full Text Available Primary nasal tuberculosis is a rare disease with nearly 40 cases reported. Our patient was a young male presented with left sided nasal obstruction, anosmia and occasional epistaxis for last 7 weeks after 6 months of blunt trauma nose. Contrast enhanced computed tomography of the para nasal sinuses showed increased soft-tissue density with contrast enhancement in the left maxillary antrum with extension through left osteomeatal foramen to the left nasal cavity along with further extension through choana to nasopharynx resulting in partial obliteration of the nasopharyngeal airway. Nasal endoscopy revealed a sessile polypoidal pinkish mass arising from the left osteomeatal foramen. Histopathological examination of excisional biopsy of that area showed caseating granuloma. Our patient diagnosed as primary nasal tuberculosis following trauma and treated with anti-tubercular chemotherapy.

Introduction. Sensitization to cat allergens is common worldwide. Currently, there is a trend towards costly and often unavailable diagnostic analysis. Objectives. The aim is to assess the reliability of skin prick test (SPT) and serum specific IgE (ssIgE) to cat sensitization, by performing nasal challenge test (NCT) in a community with low cat ownership but common presence of stray cats. Patients and methods. Forty-one pa-tients with perennial allergic rhinitis (AR) who were mono or polysensitized (including cat) were included. We had 31 cat non-owners and 10 present cat owners. SPT (> 5 mm / diameter), ssIgE (≥ 0.70 IU/ml), nasal smear for eosinophil (Eo) and NCT were compared between groups. Outcomes included nasal challenge score, nasal Eo positivity, peak inspiratory and expiratory flow (PIF and PEF) 2 and 8 hours after the NCT, and were compared to baseline. Results. Baseline SPT wheal size and ssIgE level were similar in both groups. NCT positivity was more frequent in cat owners. The strongest nasal reaction was on the top concentration in both groups. Nasal Eo positivity in cat owners was higher before and 2 hours after NCT, but similar to non-owners at last measurement. NCT positive cat non-owners had bigger SPT wheal size than NCT negative non-owners, but smaller than NCT positive cat owners. In contrast to PEF, a significant fall in PIF was noticed in both groups. Mono and polysensitised patients showed similar NCT positivity. Conclusion. Stray cats may pose a relevant risk of developing perennial AR. Regardless of cat ownership status, SPT and ssIgE should be the first diagnostic tool. Nasal Eo and NCT seem to be good diagnostic tools in cat non-owners if diagnosis is elusive.

The study aim was to compare patient satisfaction levels among patient groups with nasal hump deformity (NHD), nasal axis deviation (NAD), and NHD plus NAD using the Rhinoplasty Outcomes Evaluation Questionnaire (ROEQ) pre- and postoperatively. Forty-seven patients were divided into the NHD (n = 16), NAD (n = 13), and NHD + NAD (n = 18) groups according to the patients' physical examination results. Deviation angles were measured using frontal views and the AutoCAD 2012 computer program. Levels of patient satisfaction were assessed by the ROEQ pre- and postoperatively. The preoperative ROE scores were 6 in the NAD group and 4.9 in the NHD group. In the NAD + NHD group, the preoperative ROE score was 6.6. The postoperative ROE scores were 17.4, 21.4, and 19.1, respectively. The pre- and postoperative ROEQ scores were significantly different for all groups. The preoperative ROE score was 5.6 in women. The score was 18.6 at 6 months after surgery. In male patients, the preoperative ROE score was 6.2. The score was 20.4 at 6 months after surgery. The preoperative ROE score was 6.3 in patients younger than 30 years; the score was 19.4 in the postoperative period for this group. Preoperatively, the ROE score was 5.2 for patients older than 30 years. Postoperatively, the ROE score was 19.3 (P < .05). Patient satisfaction and quality of life should improve after rhinoplasty. Patient satisfaction ranged from high to low for patients, with the NHD group the most satisfied, followed by the NAD + NHD group and the NAD group.

Full Text Available During bronchoscopy hypoxemia is commonly found and oxygen supply can be delivered by interfaces fed with high gas flows. Recently, the high-flow nasal cannula (HFNC has been introduced for oxygen therapy in adults, but they have not been used so far during bronchoscopy in adults. Forty-five patients were randomly assigned to 3 groups receiving oxygen: 40 L/min through a Venturi mask (V40, N=15, nasal cannula (N40, N=15, and 60 L/min through a nasal cannula (N60, N=15 during bronchoscopy. Gas exchange and circulatory variables were sampled before (FiO2 = 0.21, at the end of bronchoscopy (FiO2 = 0.5, and thereafter (V40, FiO2 = 0.35. In 8 healthy volunteers oxygen was randomly delivered according to V40, N40, and N60 settings, and airway pressure was measured. At the end of bronchoscopy, N60 presented higher PaO2, PaO2/FiO2, and SpO2 than V40 and N40 that did not differ between them. In the volunteers (N60 median airway pressure amounted to 3.6 cmH2O. Under a flow rate of 40 L/min both the Venturi mask and HFNC behaved similarly, but nasal cannula associated with a 60 L/min flow produced the better results, thus indicating its use in mild respiratory dysfunctions.

2018-05-01

A relatively neglected aspect of cleft lip nasal deformity is the effect of septal deviation and inferior turbinate hypertrophy (ITH) on the functional airway. In particular, ITH in the noncleft side can be especially problematic, because it reduces the healthy nasal area, creating bilateral nasal obstruction that might affect the growth of the maxillofacial skeleton. Although these anatomic and functional changes are documented, few recommendations have been developed regarding the proper approach to ITH. The aim of the present study was to asses the ITH severity and determine the degree of nasal airway patency in patients who have undergone primary correction of the nasal septum during lip repair compared to patients operated on without primary septal correction. The study population included two groups. One group consisted of twenty unilateral cleft lip palate UCLP patients who have previously undergone primary rhinoseptoplasty as part of their treatment plan. The control group consisted of twenty UCLP patients operated on without rhinoseptal correction. The Nasal Obstructive Symptom Evaluation (NOSE) scale and nasal endoscopy were used to assess nasal obstruction. The overall untreated group reported severe symptoms across all NOSE scale dimensions more frequently than children who have undergone primary rhinoseptoplasty. The difference was statistically significant for each dimensions (p cleft lip repair results in a statistically significant reduction in IT size and improvement of nasal patency.

1997-12-01

Forty patients with nasal polyposis were studied. This study included clinical, haematological and mycological aspects. There were 24 females (60% of patients) and 16 males (40%). We found that all patients presented with nasal obstruction and nasal tone and the majority of them had allergic nasal symptoms such as sneezing and watery discharge. Thirty five percent of the patients were recurrent cases, being operated before for nasal polyps. Radiological investigations showed high of sinusitis and that 10% of the patients had complicated disease with orbital or intracranial extensions. Mycological studies revealed the presence of fungal infection in 4 patient (10%) and it was caused by Aspergillus flavus. Histological studies identified the allergic nature of the polyps in all patients. Surgical treatment was carried out in all patients and operations varied from simple intranasal polypectomy, intranasal ethmiodectomy, external ethmoidectomy to Caldwell-Luc operation for patients with antrochanal polyps.(Author)

A nasal septal abscess (NA) is defined as a collection of pus between the cartilage or bony septum and its normally applied mucoperichondrium or mucoperiostium. It is an uncommon disease which should be suspected in a patient with acute onset of nasal obstruction and recent history of nasal trauma, periodontal infection or an inflammatory process of the rhinosinusal region. We report a case of an 8-year-old boy with bilateral NA caused by community-acquired methicillin-resistant Staphylococcus aureus(MR-CO) in order to emphasize the importance of prompt diagnosis and adequate treatment to prevent the potentially dangerous spread of infection and the development of severe functional and cosmetic sequelae.

Full Text Available Background. Chronic nature of the nasal polyps, tendency to recurrence, and lack of satisfying treatment need the diagnostic’s parameters which show early inflammatory state as ferritin and hs-CRP. The Aim of Study. Assessment of hs-CRP and ferritin blood levels in nasal polyps patients in evaluation of treatment efficacy. Methods. All 38 patients were divided into 2 groups. Group I included 19 patients with anti-inflammatory therapy 2 weeks after surgery. Group II included 19 patients without anti-inflammatory therapy 2 weeks after surgery. The levels of hs-CRP and ferritin have been assessed before and 2 and 6 weeks after surgical treatment. Results. Research showed statistically significant difference of ferritin’s concentration between examined groups 6 weeks after surgery (P<0.05 and statistically significant difference of hs-CRP concentration 2 and 6 weeks after surgery (P<0.05. Conclusion. (1 The analysis of serum ferritin and hs-CRP concentrations can be useful in early postoperative detection of inflammatory state in patients with nasal polyps and for the effectiveness of therapy. (2 Lack of correlation between mean ferritin and hs-CRP serum levels, at each diagnostic and monitoring stage, shows that they are independent and cannot be determined interchangeably.

An important percentage of subjects diagnosed with chronic upper airway disease report alcohol-induced worsening of their symptoms. The prevalence and characteristics of respiratory reactions provoked by alcohol-containing drinks have not been fully investigated yet. The aim of this study was to estimate the prevalence and characteristics of alcohol hyper-responsiveness in patients with chronic airway disease and healthy controls. Furthermore, nasal inflammation was evaluated in nasal polyp patients with and without hyper-responsiveness. We evaluated the prevalence and characteristics of alcohol-induced respiratory complaints in 1281 subjects. Chronic rhinosinusitis with nasal polyps (CRSwNP) patients with and without NSAID exacerbated respiratory disease (NERD), chronic rhinosinusitis patients without nasal polyps (CRSsNP), allergic rhinitis (AR) patients and healthy controls were approached by means of a questionnaire. Inflammatory markers (eosinophilic cationic protein (ECP), IL-5, IgE, SAE-specific IgE, IL-17, TNFα and IFNγ) in tissue were then compared between alcohol hyper-responsive and non-hyper-responsive CRSwNP patients. The highest prevalence of nasal and bronchial alcohol hyper-responsiveness was observed in patients with NERD, followed by CRSwNP, and less frequent in CRSsNP, AR and healthy controls. Alcohol hyper-responsiveness is significantly more prevalent in CRSwNP patients suffering from recurrent disease and in patients with severe symptomatology. In nasal tissue of the hyper-responsive CRSwNP group, we observed significantly higher nasal levels of the eosinophilic biomarker ECP. Nasal hyper-responsiveness to alcohol is significantly more prevalent in severe eosinophilic upper airway disease. © 2016 John Wiley & Sons Ltd.

Objective Rhinoplasty, a surgical procedure that alters the shape or appearance of the nose while preserving or enhancing the nasal airway, ranks among the most commonly performed cosmetic procedures in the United States, with >200,000 procedures reported in 2014. While it is difficult to calculate the exact economic burden incurred by rhinoplasty patients following surgery with or without complications, the average rhinoplasty procedure typically exceeds $4000. The costs incurred due to complications, infections, or revision surgery may include the cost of long-term antibiotics, hospitalization, or lost revenue from hours/days of missed work. The resultant psychological impact of rhinoplasty can also be significant. Furthermore, the health care burden from psychological pressures of nasal deformities/aesthetic shortcomings, surgical infections, surgical pain, side effects from antibiotics, and nasal packing materials must also be considered for these patients. Prior to this guideline, limited literature existed on standard care considerations for pre- and postsurgical management and for standard surgical practice to ensure optimal outcomes for patients undergoing rhinoplasty. The impetus for this guideline is to utilize current evidence-based medicine practices and data to build unanimity regarding the peri- and postoperative strategies to maximize patient safety and to optimize surgical results for patients. Purpose The primary purpose of this guideline executive summary is to provide evidence-based recommendations for clinicians who either perform rhinoplasty or are involved in the care of a rhinoplasty candidate, as well as to optimize patient care, promote effective diagnosis and therapy, and reduce harmful or unnecessary variations in care. The target audience is any clinician or individual, in any setting, involved in the management of these patients. The target patient population is all patients aged ≥15 years. The guideline is intended to focus on

Introduction: There are a large number of patients with chronic respiratory symptoms especially in pediatric population in whom it would be important to rule out primary ciliary dyskinesia (PCD) by electron microscopic examination of cilia obtained from respiratory mucosal biopsies, an expensive and not widely available procedure. Our purpose was to evaluate the role of the radioisotopic mucociliary transport measurement on selecting patients for nasal or tracheobronchial biopsy. Methods: The velocity of nasal mucociliary transport (VNMT) was measured in 100 patients, aged 2m-39y, mean 9 yo, from feb-1999 until feb-2002. Ten were healthy controls. The others had chronic o recurrent respiratory symptoms. The procedure consisted to place a 99m Tc-MAA droplet in one nostril by direct vision and follows its course using a gammacamera-computer system in order to calculate its speed expressed in mm/min. Sedation was needed in the vast majority of children below 4 yo. Values below 3 mm/min were repeated to ensure an accurate result. All cases having VNMT below 2,5 mm/min underwent nasal mucosal biopsy. In some patients with VNMT above 2,5 mm/min, nasal mucosal biopsy was also done based on other considerations. Patients were classified in three groups. Those having respiratory symptoms and no biopsy done (CRRS.NB); patients with respiratory symptoms and PCD diagnosed by biopsy (CRRS.PCD.B (+)); healthy controls. Results: Al cases with CRRS. PCD.B(+) had VNMT below 2.4 mm/min with a mean significantly different from those in CRRS.NB and healthy controls. There were no overlapping between the VNMT highest value in patients having CRRS. PCD.B(+) and the lowest VNMT in CRRS.NB or healthy controls. The results are similar to those published by other centers. Conclusions: The radioisotopic method to measure VNMT is feasible, inexpensive and relatively easy to perform. As PCD has important differences in prognosis and treatment from other conditions with similar symptoms, it is

Leishmania is currently one of the most clinically important protozoa in otorhinolaryngology. Mediterranean countries, including Spain, have endemic HIV and L. infantum. Dogs are the most important Leishmania reservoir. Leishmaniasis is transmitted basically by the bite of infected female Phlebotomus sandflies. Its clinical development depends mainly on the host's cellular immunity (TCD4+ lymphocyte count). About 400 cases of HIV-visceral leishmaniasis have been reported in Spain. However, exclusively cutaneous presentation of HIV-leishmaniasis coinfection has been observed in only 2-3% of cases. We report the case of a female HIV+ patient who developed cutaneous leishmaniasis of the nasal vestibule by L. infantum. The patient was treated satisfactorily with a combination of parenteral Pentostam (sodium stilbogluconate) and periodic intralesional injections of Pentostam. The patient was included in a secondary prophylaxis protocol for visceral leishmaniasis with a monthly dose of Glucantime (meglumine antimoniate) for life.

Nasal deviation is a common complaint in otorhinolaryngology and plastic surgery. This condition not only causes impairment of nasal function but also affects quality of life, leading to psychological distress. The subjective assessment of quality of life, as an important aspect of outcomes research, has received increasing attention in recent decades. Quality of life is measured using standardized questionnaires that have been tested for reliability, validity, and sensitivity. The aim of this study was to evaluate health-related quality of life, self-esteem, and depression in patients with nasal deviation. Sixty patients were selected for the study. Patients with nasal deviation (n = 32) were assigned to the study group, and patients without nasal deviation (n = 28) were assigned to the control group. The diagnosis of nasal deviation was made by digital photogrammetry. Quality of life was assessed using the Medical Outcomes Study 36-Item Short Form Health Survey questionnaire; the Rosenberg Self-Esteem/Federal University of São Paulo, Escola Paulista de Medicina Scale; and the 20-item Self-Report Questionnaire. There were significant differences between groups in the physical functioning and general health subscales of the Medical Outcomes Study 36-Item Short Form Health Survey (p < 0.05). Depression was detected in 11 patients (34.4 percent) in the study group and in two patients in the control group, with a significant difference between groups (p < 0.05). Nasal deviation is an aspect of rhinoplasty of which the surgeon should be aware so that proper psychological diagnosis can be made and suitable treatment can be planned because psychologically the patients with nasal deviation have significantly worse quality of life and are more prone to depression.

Full Text Available Abstract Background Osteopontin (OPN is a multifunctional cytokine that has been primarily investigated in Th1 diseases. Recently, it has also been implicated in Th2-mediated allergic diseases, such as asthma. The expression of OPN in allergic rhinitis (AR is currently unknown, as is the effect of intranasal glucocorticosteroids (GCs on that expression. Methods Subjects with AR were randomised to receive treatment with fluticasone propionate (FP (n = 12 or a placebo (n = 16 over the grass pollen season and nasal biopsies were taken prior to, and during the season. OPN expression in the nasal mucosa was examined with immunohistochemistry. Healthy non-AR controls (n = 5 were used as a comparator. Results OPN expression was detected in epithelial cells, subepithelial infiltrating/inflammatory cells and cells lining the vessels and glands of all subjects. Comparison of the pre- and peak-pollen season biopsy sections in placebo treated patients revealed no increase in OPN expression during the grass pollen season (5.7% vs 6.4%. Treatment with a local glucocorticosteroid did not alter the expression of OPN during pollen exposure (6.2% vs 6.7%. Conclusion OPN has been increasingly associated with the pathogenesis of various Th2-mediated diseases. However, our finding that the OPN expression in the nasal mucosa of AR patients is not significantly affected by allergen exposure and is comparable to that of the healthy controls, suggests that intracellular OPN is not directly involved in the pathogenesis of allergic rhinitis.

Full Text Available Aim: Nose is a resonator organ in production of voice. The aim of this study was to evaluate the effects of nasal obstruction caused by nasal polyposis on voice quality subjectively. Methods: Thirty-six patients diagnosed with nasal polyposis were included in the study. The 30-item voice handicap index 30 was used in order to evaluate subjective status of voice. Nasal endoscopy and computed tomography imaging of the paranasal sinuses were performed for each patient. Lund-Kennedy endoscopy scores and Lund-MacKay computed tomography scores were evaluated. Control group composed of 20 healthy subjects. Results: The mean voice handicap score in the patient group was 43.16 (SD 15.53 and it was 2.15 (SD 1.92 in control group. There was a statistically significant difference between the groups (p=0.001. The mean Lund-Kennedy and Lund-Mackay scores were 8.58 (SD 2.5 and 17 (SD 5.52, respectively. It was found that increased severity of nasal polyposis was the cause for decreased satisfaction with voice quality. Conclusion: Nasal obstruction caused by nasal polyposis affects voice quality adversely and as the severity of nasal polyposis increases, satisfaction with voice quality decreases.

Obstructive sleep apnea syndrome (OSAS) has been shown to be associated to upper and lower airways inflammation. Continuous positive airway pressure (CPAP) is the elective treatment of OSAS. The aim of the present study was to assess the effect of CPAP-therapy on airway and nasal inflammation. In 13 non-smoking subjects affected by untreated OSAS and in 11 non-smoking normal volunteers, airway inflammation was detected by analyses of the induced sputum. In the OSAS group measurements were repeated after 1, 10 and 60 days of the appropriate CPAP treatment. In addition, in 12 subjects of the OSAS group, nasal inflammation was detected by the analysis of induced nasal secretions at baseline, and after 1, 10 and 60 days of CPAP treatment. OSAS patients, compared to normal controls, showed at baseline a higher percentage of neutrophils and a lower percentage of macrophages in the induced sputum. One, 10 and 60 days of appropriate CPAP-therapy did not change the cellular profile of the induced sputum. In addition, in the OSAS patients, the high neutrophilic nasal inflammation present under baseline conditions was not significantly modified by CPAP-therapy. Finally, no patients developed airway hyper-responsiveness after CPAP therapy. In OSAS subjects, the appropriate CPAP-therapy, while correcting the oxygen desaturation, does not modify the bronchial and nasal inflammatory profile.

Patients with obstructive sleep apnea are frequently considered unsuitable candidates for awake craniotomy due to anticipated problems with oxygenation, ventilation, and a potentially difficult airway. At present, only a handful of such accounts exist in the literature. Our report describes the novel use of high-flow nasal oxygen therapy for a patient with moderate obstructive sleep apnea who underwent an awake craniotomy under deep sedation. The intraoperative application of high-flow nasal oxygen therapy achieved satisfactory oxygenation, maintained the partial carbon dioxide pressure within a reasonable range even during periods of deep sedation, permitted responsive patient monitoring during mapping, and provided excellent patient and surgeon satisfaction.

Objective: To investigate the clinical symptoms and immunology inspection characteristics of nasal cavity local allergy. Method: Selected 60 patients as observation group, who had only nasal local allergy symptoms, allergen skin prick test and serum allergen specific IgE (SIgE) test were negative, 40 allergic rhinitis (AR) patients and 40 healthy volunteers as control groups. To detect Symptom scores and VAS scores, and eosinophilia counts in venous blood, allergen skin prick test (SPT), serum allergen SIgE test, nasal secretions allergen SIgE test, nasal mucous membrane excitation test in both observation group and AR group, eosinophilia counts in nasal secretion, taked the data for statistical analysis. Result: There was no difference ( P > 0.05) in the symptom scores and VAS scores of observation group and the AR group. The eosinophilia counts in venous blood in the AR group were higher than in the observation group ( P 0.05) in the eosinophilia percentages in nasal secretion in the observation group and the AR group. There was significant difference ( P < 0.05) in the eosinophilia percentages in nasal secretion in the observation group and the healthy volunteers group. There were 6 patients in observation group whose nasal secretions allergen SIgE test and nasal mucous membrane excitation test were both negative, could be diagnosised as non-allergic rhinitis (NAR). According to eosinophilia counts in venous blood and nasal secretions, 4 patients were diagnosised as vasomotor rhinitis and 2 patients were diagnosised as NAR with eosinophilia syndrome. There were 54 patients in observation group whose nasal secretions allergen SIgE test and (or) nasal mucous membrane excitation test were positive, could be diagnosised as local allergic rhinitis. After three years, all of the observation group patients were detected with SPT and serum allergen SIgE test. Five patients diagnosed as local allergic rhinitis before three years were positive.

To evaluate the cost-effectiveness of Floseal, a topically applied hemostatic agent, and nasal packing for the management of epistaxis in Canada. Outcomes research, a cost-utility analysis. We developed a Markov model to compare the costs and health outcomes of Floseal with nasal packing over a lifetime horizon from the perspective of a publicly funded healthcare system. A cycle length of 1 year was used. Efficacy of Floseal and packing was sought from the published literature. Unit costs were gathered from a hospital case costing system, whereas physician fees were extracted from the Ontario Schedule of Benefits for Physician Services. Results were expressed as an incremental cost per quality-adjusted life year (QALY) gained. A series of one-way sensitivity and probabilistic sensitivity analyses were performed. From the perspective of a publicly funded health are system, the Floseal treatment strategy was associated with higher costs ($2,067) and greater QALYs (0.27) than nasal packing. Our findings were highly sensitive to discount rates, the cost of Floseal, and the cost of nasal packing. The probabilistic sensitivity analysis suggested that the probability that Floseal treatment is cost-effective reached 99% if the willingness-to-pay threshold was greater than $120,000 per QALY gained. Prior studies have demonstrated Floseal to be an effective treatment for anterior epistaxis. In the Canadian healthcare system, Floseal treatment appears to be a cost-effective treatment option compared to nasal packing for anterior epistaxis. 2c Laryngoscope, 2018. © 2018 The American Laryngological, Rhinological and Otological Society, Inc.

2014-01-01

Full Text Available Introduction: Neonatal nasal airway obstruction induces various degrees of respiratory distress. The management of this disease, including surgical repair, will depend on the severity and location of the obstruction. We describe here a case of congenital nasal nostril stenosis that required surgical repair for stenting of both nares after coanal atresia repair.   Case Report: A 2 days old female newborn referred to neonatal department of Tabriz Children’s Hospital affiliated to the University of Medical Sciences of Tabriz, Iran on the 3rd of December, 2011 immediately after birth with respiratory distress due to bilateral coanal atresia and nasal hypoplasia with very small nostrils. CT scan showed normal brain and bilateral choanal atresia with normal size Pyriform apertures.   Conclusion: Nasal obstruction can lead to airway compromise and respiratory distress. Congenital bony nasal deformities are being recognized as an important cause of newborn airway obstruction. Nasal hypoplasia is seen in many craniofacial syndromes. Although our patient had hypoplastic nostrils with respiratory distress due to bilateral coanal atresia, correction of hypoplastic nostrils was necessary for completing the operation of choanal atresia.

2016-01-01

High-flow nasal cannula (HFNC) oxygen therapy has several physiological advantages over traditional oxygen therapy devices, including decreased nasopharyngeal resistance, washing out of the nasopharyngeal dead space, generation of positive pressure in the pharynx, increasing alveolar recruitment in the lungs, humidification of the airways, increased fraction of inspired oxygen and improved mucociliary clearance. Recently, the use of HFNC in treating adult critical illness patients has significantly increased, and it is now being used in many patients with a range of different disease conditions. However, there are no established guidelines to direct the safe and effective use of HFNC for these patients. This review article summarizes the available published literature on the positive physiological effects, mechanisms of action, and the clinical applications of HFNC, compared with traditional oxygen therapy devices. The available literature suggests that HFNC oxygen therapy is an effective modality for the early treatment of critically adult patients. PMID:27698207

2013-09-01

Migraine attacks exclusively felt in the face are very rare, the pain involving the territories supplied by the second and third branches of the trigeminal nerve. Two patients suffering from heminasal pain attacks accompanied with typical migrainous features and responsive to oral or intranasal triptans - but not to intranasal lidocaine or oxymetazoline. In one patient, the attacks could be precipitated upon slight touching on the tip of the nose, in the other attacks were preceded by the nasal sensation typically heralding sneezing. Migraine pain mostly develops within the innervation territory of the first branch of the trigeminal nerve, which includes the nose. Therefore, episodes of unilateral nasal pain with migrainous features could be considered a migraine with unusual topography (nasal migraine). Painful nasal attacks occasionally preceded by stimulation of trigeminal afferents in the nose, could be conceived of as migraine-tic syndrome.

Kartagener's syndrome presented with nasal obstruction: A case report

Full Text Available The nasal polyposis is a chronic inflammatory process of the nasal mucosa. Although it is rare in children, there may be also association with cystic fibrosis and primary ciliary dyskinesia. About 50% of primary ciliary dyskinesia patients develop situs inversus and it is known as Kartagener's syndrome. The Kartagener's sydrome is a rare autosomal recessive disorder characterized by sinusitis, bronchiectasis, situs inversus. Clinically, patients present to the otolaryngologist with nasal obstruction. We as pediatricians, should consider nasal polyposis as a rare cause of nasal obstruction in children. In the presence of recurrent upper and lower respiratory tract infections accompanying nasal polyposis, Kartagener's syndrome must be kept in mind as a rare reason.

2015-01-01

The purpose of this study is to ascertain objective nasal measurements from the basal view that are predictive of nasal esthetics in individuals with secondary cleft nasal deformity. Thirty-three patients who had undergone unilateral cleft lip repair were retrospectively reviewed in this study. The degree of nasal deformity was subjectively ranked by seven surgeons using standardized basal-view measurements. Nine physical objective parameters including angles and ratios were measured. Correlations and regressions between these objective and subjective measurements were then analyzed. There was high concordance in subjective measurements by different surgeons (Kendall's harmonious coefficient = W = .825, P = .006). The strongest predictive factors for nasal aesthetics were the ratio of length of nasal alar (r = .370, P = .034) and the degree of deviation of the columnar axis (r = .451, P = .008). The columellar angle had a more powerful effect in rating nasal esthetics. There was reliable concordance in subjective ranking of nasal esthetics by surgeons. Measurement of the columnar angle may serve as an independent, objective predictor of esthetics of the nose.

Nasal birth trauma: a review of appropriate treatment.

Cashman, E C

2012-02-01

The aetiology of nasal deformity has frequently included birth trauma. There is no consensus in the literature as to whether nasal surgery, in the form of closed reduction, is indicated in neonates. The majority of studies in the literature that advocate intervention have inadequate followup periods and there is a paucity of evidence for the adverse effects of conservative management. This case highlights the therapeutic dilemma posed by such nasal injuries in the neonate and, to the best of the authors\\' knowledge, at the time of writing, represents the earliest reported case in the literature of nasal deformity in the neonate. The term nasal deformity is used to denote deformity of the nasal pyramid, soft tissue, and septum. Three main aspects of neonatal nasal deformity are addressed including, firstly, if nasal deformity at birth needs to be addressed, secondly, if left unaltered, what the long-term effects are and, finally, if intervention alters the normal course of midfacial development.

Our aim in this study was to determine the angle of the internal nasal valve in Mexican patients with the "mestizo nose" feature and without nasal obstructive symptoms. The work was prospective, comparative, and observational in nature and included patients >14 years of age who were seen in the Otolaryngology Department at the Los Angeles Lomas Hospital between April and May 2016. The angle of the internal nasal valve was measured in 30 patients without obstructive symptoms. Endoscopic examination was performed with a 0° endoscope framed with tape at a 13-mm distance from the endoscope's tip, and digital photographs of the internal nasal valve were taken. The measurement of the angle of the internal nasal valve was made in sexagesimal degrees using Golden Ratio v3.1 (2012) software. Statistical analysis was performed using Excel v15.13.3. The angles of the internal nasal valve of the patients were (mean ± standard deviation) 24.07 ± 4.8° for the right nasal cavity and 25.07 ± 5.0° for the left nasal cavity, wider than the angle reported in the normal Caucasian nose established in the literature. According to our results, the Mexican-Hispanic mestizo nose has a wider angle in the internal nasal valve than that considered normal in the literature (10°-15°). We believe it is necessary to undertake a second study and add an airflow resistance measurement with a rhinomanometry procedure so we can compare the results with those in the Caucasian population. © 2018 ARS-AAOA, LLC.

Omalizumab, a monoclonal antibody against IgE, may be effective on nasal polyps, but its use is not currently authorized to treat that disease. We report the cases of three patients who were given omalizumab for asthma after undergoing nasal surgical polypectomy. Although such procedure is frequently followed by polyp recurrence, none of the three patients developed this complication, and in one subject the regression of initial polyp return was registered after starting omalizumab. Our data support the hypothesis that omalizumab may be useful to treat nasal polyposis.

2017-08-01

Various case reports on nasal myiasis written during the 1990s and 2000s state that nasal myiasis, which is known as peenash among South Asian natives, is a form of divine punishment in Hindu mythology, but do not provide citations from Hindu scriptures that would suggest this interpretation. This paper aims to discuss the phenomenon of peenash in a historical context by examining medical literature written during the nineteenth and early twentieth centuries, to identify Hindu texts contributing to the belief of some Hindus that nasal myiasis is a form of divine punishment, and to provide an overview of contemporary treatment for and management of nasal myiasis.

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)

To evaluate the role of nasal bacterial colonization in cases of idiopathic epistaxis in children. A descriptive, hospital based, observational study in our hospital was conducted on total 112 pediatric patients in the age group 4-16 years. Group A (control): 56 patients with no epistaxis; Group B (epistaxis): 56 patients with idiopathic epistaxis. A swab for microbiological evaluation was taken from the anterior nasal cavity of each child. A highly significant association between nasal colonization with pathological Staphylococcus aureus and idiopathic epistaxis was found. The presence of pathological S. aureus colonization in the anterior nasal cavity was also associated with statistically significant number of crusting and presence of dilated blood vessels on the anterior nasal septum of children in epistaxis group. Nasal bacterial colonization with S. aureus leads to a sequence of pathological events i.e. low grade inflammation, crusting and new vessel formation. This leads to irritation in nasal cavity resulting in digital trauma and subsequently epistaxis and thus it plays an important role in causing idiopathic epistaxis in children.

The purpose of this study is to evaluate the size of the olfactory bulb using MRI in normal volunteers and anosmic or hyposmic patients without nasal diseases. MRI performed in 20 normal volunteers with a normal sense of smell, and in 15 anosmic or hyposmic or hyposmic patients without nasal disease but with abnormality in the olfactory function test. Coronal T1-weighted MRI was performed, with a section thickness of 3 mm. The cross sectional area, width and height of the olfactory bulb were measured in multiple sequential images and the largest values of these were analysed. The difference in the size of the olfactory bulb between normal volunteers and anosmic or hyposmic patients was evaluated and student''s test was used for statistical analysis. The size of the olfactory bulb is significantly less in anosmic or hyposmic patients without nasal disease than in normal volunteers; in such patients, olfactory MRI could be a useful evaluative modality.

Nasal bone fracture is the most common type of facial bone fracture. The optimal duration of the packing after closed reduction has been a controversial issue. The packing has several disadvantages such as blocking the nasal airway, causing infection and a headache, which is the most common immediate complication. The present study investigated the minimal and optimal duration of the nasal packing following reduction surgery of nasal bone fracture. A prospective study was performed for the patients undergoing reduction surgery following nasal bone fracture between July 2010 and June 2012. The patients were categorised into three groups according to the duration of nasal packing. For the patients treated between July 2010 and June 2011, nasal packing was maintained for 5 days. For those between July 2011 and December 2011, packing was maintained for 3 days. For those between January 2012 and June 2012, the packing was removed after 1 day. The computed tomography scan and the cephalolateral X-ray were checked at immediate postoperative period after packing removal and 6 months postoperatively. The alteration of heights, deviations, and nasal bone contours with time passage were compared among three groups. The patient satisfaction survey was also performed and compared. A total of 530 patients including 322 of the 5-days packing group, 102 of the 3-days group, and 106 of the 1-day group were enrolled. There was no statistically significant difference between the groups in terms of heights, deviations, and nasal bone contours (p-value ≥ 0.05). In the patient satisfaction survey, the 1-day packing group complained of discomfort related to nasal packing and headache symptoms much less, compared to the other two groups. The present study demonstrated that 1-day packing had comparable postoperative outcome with reducing the patients' discomfort. As such, a longer packing duration was not needed to achieve stable results one day is a reasonable packing time for most

Abstract In this study, we analyze and discuss the treatments of postoperative nasal complications after endonasal transsphenoidal resection of pituitary neoplasms (PNs). We performed 129 endonasal transsphenoidal resections of PNs and analyzed and treated cases with nasal complications. After endonasal transsphenoidal resection of PNs, there were 26 cases of postoperative nasal complications (20.1%), including nasal hemorrhage (4.8%), cerebrospinal fluid rhinorrhea (6.9%), sphenoid sinusitis (2.3%), atrophic rhinitis (1.6%), olfactory disorder (1.6%), perforation of nasal septum (0.8%), and nasal adhesion (2.3%). All patients clinically recovered after therapy, which included treatment of the cavity through nasal endoscopy, intranasal corticosteroids, and nasal irrigation. We propose that regular nasal endoscopic review, specific nasal medications, and regular nasal irrigation can effectively clear nasal mucosal hyperemia-induced edema and nasal/nasoantral secretions, as well as promote regeneration of nasal mucosa, prevent nasal adhesion, maintain the sinus cavity drainage, and accelerate the recovery of the physiological function of the paranasal sinus. Timely treatment of patients with nasal complications after endonasal transsphenoidal resections of PNs could greatly relieve the clinical symptoms. Nasal cleaning is very beneficial to patients after surgery recovery. PMID:28403108

Topical application of timolol decreases the severity and frequency of epistaxis in patients who have previously undergone nasal dermoplasty for hereditary hemorrhagic telangiectasia.

Hereditary hemorrhagic telangiectasia (HHT) is widely known to cause bleeding that is difficult to control because of the associated vascular wall fragility. Although nasal dermoplasty results in decreased severity and frequency of nasal bleeding in patients with HHT, it does not eradicate epistaxis because this procedure cannot cover the entire nasal cavity. Residual bleeding warrants additional effective therapy. Preliminary reports on the use of β-adrenergic blockers for treating epistaxis in patients with HHT encouraged us to examine their effects in HHT patients who had previously undergone nasal dermoplasty but still complained of epistaxis. We performed a prospective topical timolol, a nonselective beta blocker, application study involving 12 HHT patients who had undergone nasal dermoplasty. The observation period lasted for 3 months. There was one improperly enrolled case in which timolol administration was discontinued. The mean score of bleeding intensity and that of bleeding frequency were markedly reduced after treatment. Two patients who had required transfusions before treatment did not need them afterward, and patients were generally satisfied with the treatment. Topical timolol application was effective in decreasing epistaxis. Although no adverse effects were observed in the properly selected patients, there are contraindications to timolol application that should be kept in mind when applying this treatment.

Full Text Available Reconstruction of nasal defects must preserve the integrity of complex facial functions and expressions, as well as facial symmetry and a pleasing aesthetic outcome. The reconstructive modality of choice will depend largely on the location, size, and depth of the surgical defect. Individualized therapy is the best course, and numerous flaps have been designed to provide coverage of a variety of nasal-specific defects. We describe our experience in the aesthetic reconstruction of nasal skin defects following oncological surgery. The use of different local flaps for nasal skin cancer defects is reported in 286 patients. Complications in this series were one partial flap dehiscence that healed by secondary intention, two forehead flaps, and one bilobed flap with minimal rim necrosis that resulted in an irregular scar requiring revision. Aesthetic results were deemed satisfactory by all patients and the operating surgeons. The color and texture matches were aesthetically good, and the nasal contour was distinct in all patients. All scars were inconspicuous and symmetrical. No patient had tenting or a flat nose.

Full Text Available Anterior nasal spine fractures are a quite rare type of nasal bone fractures. Associated cervical spine injuries are more dangerous than the nasal bone fracture. A case of the anterior nasal spine fracture, in a 18-year-old male was presented. Fracture of the anterior nasal spine, should be considered in the differential diagnosis of the midface injuries and also accompanying cervical spine injury should not be ignored.

Septoplasty is one of the most commonly performed procedures in otolaryngology practice. Prophylactic use of antibiotics is controversial. Disruption of nasal flora may predispose individuals to infection. We investigated the effect of antibiotic prophylaxis and septoplasty on nasal flora. We included 115 consecutive patients who underwent septoplasty because of symptomatic nasal septal deviation. Patients were divided into study and control groups. Study patients received prophylactic parenteral sodium cefazoline twice a day beginning intra-operatively and while the nasal packing remained in the nose for 48 h, and expandable polyvinyl acetate (Merocel) packing covered with antibiotic ointment containing 0.2% nitrofurazone was inserted into each nostril at the end of the operation. Control patients received neither parenteral antibiotic prophylaxis nor antibiotic ointment around the Merocel packs. Both groups received oral prophylactic cefuroxime axetil for 5 d after nasal packing was removed. Nasal flora was determined pre-operatively, post-operatively when nasal packing was removed, and 3 mo after surgery. Study patients were compared to control patients at pack removal and 1 mo after surgery The effect of antibiotic use in septoplasty on nasal flora was as follows: Increased isolation rate of gram-positive rods (p = 0.007), decreased methicillin-sensitive coagulase-negative staphylococci (p = 0.002). Pre-operative and post-operative culture results at 3 mo were compared. The effect of septoplasty on nasal flora was as follows: Decreased coagulase-negative staphylococci (p = 0.05), decreased Klebsiella (p flora. Antibiotics do not protect against S. aureus colonization and contribute to a decrease in normal flora. Antibiotics do not seem to confer benefit in terms of flora changes. Studies investigating flora changes with a longer follow-up should be conducted.

Full Text Available ABSTRACT INTRODUCTION: Chronic rhinosinusitis with nasal polyps is a multifactorial disease entity with an unclear pathogenesis. Contradictory data exist in the literature on the potential implication of viral elements in adult patients with chronic rhinosinusitis. OBJECTIVE: To compare the prevalence of human herpes viruses (1-6 and Human Papilloma Virus in adult patients with chronic rhinosinusitis with nasal polyps and healthy controls. METHODS: Viral DNA presence was evaluated by real-time polymerase chain reaction application to nasal polyps specimens from 91 chronic rhinosinusitis with nasal polyps patients and nasal turbinate mucosa from 38 healthy controls. RESULTS: Epstein-Barr virus positivity was higher in nasal polyps (24/91; 26.4% versus controls (4/38; 10.5%, but the difference did not reach significance (p = 0.06. Human herpes virus-6 positivity was lower in nasal polyps (13/91; 14.29% versus controls (10/38; 26.32%,p = 0.13. In chronic rhinosinusitis with nasal polyps group, 1 sample was herpes simplex virus-1-positive (1/91; 1.1%, and another was cytomegalovirus-positive (1/91; 1.1%, versus none in controls. No sample was positive for herpes simplex virus-2, varicella-zoster virus, high-risk-human papilloma viruses (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 and low-risk-human papilloma viruses (6, 11. CONCLUSION: Differences in Epstein-Barr virus and human herpes virus-6 positivity among patients with chronic rhinosinusitis with nasal polyps and healthy controls are not statistically significant, weakening the likelihood of their implication in chronic rhinosinusitis with nasal polyps pathogenesis.

The use of high-flow nasal cannula in the pediatric emergency department

Directory of Open Access Journals (Sweden)

Katherine N. Slain

Full Text Available Abstract Objectives: To summarize the current literature describing high-flow nasal cannula use in children, the components and mechanisms of action of a high-flow nasal cannula system, the appropriate clinical applications, and its role in the pediatric emergency department. Sources: A computer-based search of PubMed/MEDLINE and Google Scholar for literature on high-flow nasal cannula use in children was performed. Data summary: High-flow nasal cannula, a non-invasive respiratory support modality, provides heated and fully humidified gas mixtures to patients via a nasal cannula interface. High-flow nasal cannula likely supports respiration though reduced inspiratory resistance, washout of the nasopharyngeal dead space, reduced metabolic work related to gas conditioning, improved airway conductance and mucociliary clearance, and provision of low levels of positive airway pressure. Most data describing high-flow nasal cannula use in children focuses on those with bronchiolitis, although high-flow nasal cannula has been used in children with other respiratory diseases. Introduction of high-flow nasal cannula into clinical practice, including in the emergency department, has been associated with decreased rates of endotracheal intubation. Limited prospective interventional data suggest that high-flow nasal cannula may be similarly efficacious as continuous positive airway pressure and more efficacious than standard oxygen therapy for some patients. Patient characteristics, such as improved tachycardia and tachypnea, have been associated with a lack of progression to endotracheal intubation. Reported adverse effects are rare. Conclusions: High-flow nasal cannula should be considered for pediatric emergency department patients with respiratory distress not requiring immediate endotracheal intubation; prospective, pediatric emergency department-specific trials are needed to better determine responsive patient populations, ideal high-flow nasal cannula

There are, however, some limitations to the study that need to be considered.    First, this study has a small number of patients, particularly in groups A and B, which in our opinion will affect the comparison of data with the group C that contains a greater variety of patients with more severe outcomes, including forced expiratory volume in 1 second and forced vital capacity. Second, as a study on mean airway pressure, it would be interesting to evaluate partial pressure of CO2 with higher flows.    Third, one of the aims of this study was to characterize changes in hypercapnia, so it is not correct to include nonhypercapnic patients. Fourth, it would be interesting to know the FiO2 that was given and whether the patients had domiciliary oxygen or noninvasive ventilation, as most of them are hypercapnic patients. Finally, regarding comfort and dyspnea scale, HFNC showed better results, which may increase its use when intolerant to noninvasive ventilation.    In short, HFNC is an interesting mode for the future treatment of COPD patients with respiratory failure, which may lead to larger and randomized trials to confirm this indication.View original paper by Bräunlich et al.

2015-08-01

Malignant tumors in the nasal region may be treated by means of invasive surgical procedures, with large facial losses. Nasal prostheses, retained by osseointegrated facial implants, instead of plastic surgery, will, in most patients, offer good biomechanical and cosmetic results. This clinical report describes the prosthetic rehabilitation of a patient with nasal cancer who had the entire nasal vestibule removed in a single-stage surgical procedure in order to shorten the rehabilitation time. The nasal prosthesis was built on a 3-magnet bar and was made of platinum silicone with intrinsic pigmentation, thereby restoring the patient's appearance and self-esteem. The authors concluded that single-stage implants may reduce the rehabilitation time to as little as 1 month, and the correct use of materials and techniques may significantly improve the nasal prosthesis.

There are few studies of the effects of nasal snuff and environmental factors on the risk of nasal cancer. This study aimed to investigate the impact of using nasal snuff and of other risk factors on the risk of nasal cancer in German men. A population-based case-control study was conducted in the German Federal States of Bavaria and Baden-Württemberg. Tumor registries and ear, nose and throat departments provided access to patients born in 1926 or later. Telephone interviews were conducted with 427 cases (mean age 62.1 years) and 2.401 population-based controls (mean age 60.8 years). Ever-use of nasal snuff was associated with an odds ratio (OR) for nasal cancer of 1.45 (95% confidence interval [CI] 0.88-2.38) in the total study population, whereas OR in smokers was 2.01 (95% CI 1.00-4.02) and in never smokers was 1.10 (95% CI 0.43-2.80). The OR in ever-smokers vs. never-smokers was 1.60 (95% CI 1.24-2.07), with an OR of 1.06 (95% CI 1.05-1.07) per pack-year smoked, and the risk was significantly decreased after quitting smoking. Exposure to hardwood dust for at least 1 year resulted in an OR of 2.33 (95% CI 1.40-3.91) in the total population, which was further increased in never-smokers (OR 4.89, 95% CI 1.92-12.49) in analyses stratified by smoking status. The OR for nasal cancer after exposure to organic solvents for at least 1 year was 1.53 (1.17-2.01). Ever-use of nasal sprays/nasal lavage for at least 1 month rendered an OR of 1.59 (1.04-2.44). The OR after use of insecticides in homes was 1.48 (95% CI 1.04-2.11). Smoking and exposure to hardwood dust were confirmed as risk factors for nasal carcinoma. There is evidence that exposure to organic solvents, and in-house use of insecticides could represent novel risk factors. Exposure to asbestos and use of nasal snuff were risk factors in smokers only.

We investigated the remifentanil effect-site concentration in 50% (EC50 of the elderly patients undergoing nasal surgery for smooth emergence without cough and compared it with that of adult patients.Methods: Twenty-two elderly (aged 65–80 years and 25 adult patients (aged 20–60 years with an American Society of Anesthesiologists physical status I/II undergoing nasal surgery were enrolled. Anesthesia was maintained with sevoflurane and remifentanil. Remifentanil EC50 and EC95 for preventing cough were determined using the modified Dixon’s up-and-down method and isotonic regression with bootstrapping approach. Recovery profiles were also recorded.Results: With Dixon’s up-and-down method, the EC50 of remifentanil in elderly patients (2.40±0.25 ng/mL was not significantly different from that of adults (2.33±0.30 ng/mL (P=0.687. With isotonic regression, the EC95 of remifentanil in elderly patients (3.32 [95% confidence interval: 3.06–3.38] ng/mL was not significantly different from that of adults (3.30 [95% confidence interval: 2.96–3.37] ng/mL. However, eye opening time (14.1±3.8 vs 12.0±2.9 seconds, extubation time (17.2±4.1 vs 14.0±3.0 seconds, and postanesthesia care unit duration (44.5±7.6 vs 38.7±3.4 minutes in elderly patients were significantly longer than those in adults (P<0.05.Conclusion: Remifentanil EC50 for preventing cough after nasal surgery with sevoflurane anesthesia did not differ between elderly and adult patients.

Poor mask fit and mouth leak are associated with nasal symptoms and poor sleep quality in patients receiving domiciliary non-invasive ventilation (NIV) through a nasal mask. Normal subjects receiving continuous positive airways pressure demonstrate increased nasal resistance following periods of mouth leak. This study explores the effect of mouth leak during pressure-targeted nasal NIV, and whether this results in increased nasal resistance and consequently a reduction in effective ventilatory support. A randomised crossover study of 16 normal subjects was performed on separate days. Comparison was made of the effect of 5 min of mouth leak during daytime nasal NIV with and without heated humidification. Expired tidal volume (V(T)), nasal resistance (R(N)), and patient comfort were measured. Mean change (Delta) in V(T) and R(N) were significantly less following mouth leak with heated humidification compared to the without (DeltaV(T) -36+/-65 ml vs. -88+/-50 ml, phumidification (5.3+/-0.4 vs. 6.2+/-0.4, phumidification. In normal subjects, heated humidification during nasal NIV attenuates the adverse effects of mouth leak on effective tidal volume, nasal resistance and improves overall comfort. Heated humidification should be considered as part of an approach to patients who are troubled with nasal symptoms, once leak has been minimised.

Chronic rhinosinusitis with nasal polyps is a multifactorial disease entity with an unclear pathogenesis. Contradictory data exist in the literature on the potential implication of viral elements in adult patients with chronic rhinosinusitis. To compare the prevalence of human herpes viruses (1-6) and Human Papilloma Virus in adult patients with chronic rhinosinusitis with nasal polyps and healthy controls. Viral DNA presence was evaluated by real-time polymerase chain reaction application to nasal polyps specimens from 91 chronic rhinosinusitis with nasal polyps patients and nasal turbinate mucosa from 38 healthy controls. Epstein-Barr virus positivity was higher in nasal polyps (24/91; 26.4%) versus controls (4/38; 10.5%), but the difference did not reach significance (p=0.06). Human herpes virus-6 positivity was lower in nasal polyps (13/91; 14.29%) versus controls (10/38; 26.32%, p=0.13). In chronic rhinosinusitis with nasal polyps group, 1 sample was herpes simplex virus-1-positive (1/91; 1.1%), and another was cytomegalovirus-positive (1/91; 1.1%), versus none in controls. No sample was positive for herpes simplex virus-2, varicella-zoster virus, high-risk-human papilloma viruses (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59) and low-risk-human papilloma viruses (6, 11). Differences in Epstein-Barr virus and human herpes virus-6 positivity among patients with chronic rhinosinusitis with nasal polyps and healthy controls are not statistically significant, weakening the likelihood of their implication in chronic rhinosinusitis with nasal polyps pathogenesis.

Side-effects directly due to the nasal mask are common in patients with obstructive sleep apnoea syndrome (OSAS) commencing continuous positive airway pressure (CPAP). Recently, nasal pillows have been designed to overcome these issues. Limited evidence exists of the benefits and effectiveness of these devices. Twenty-one patients (19 male, 49+\\/-10years) with the established diagnosis of OSAS [apnoea\\/hypopnoea index (AHI): 52+\\/-22] and who had a successful CPAP titration were commenced on CPAP therapy (10+\\/-2cmH2O), and randomized to 4weeks of a nasal pillow (P) and a standard nasal mask (M) in a crossover design. Outcome measures were objective compliance, AHI, quality of life, Epworth Sleepiness Score (ESS) and CPAP side-effects. There was no difference in compliance (M versus P: 5.1+\\/-1.9h versus 5.0+\\/-1.7h; P=0.701) and AHI (2.6+\\/-2.7 versus 3.0+\\/-2.9; P=0.509). Quality of life and ESS improved with CPAP, but there was no difference in the extent of improvement between both devices. Usage of nasal pillows resulted in less reported pressure on the face and more subjects found the nasal pillow the more comfortable device. However, there was no clear overall preference for either device at the end of the study (mask=57%, pillow=43%; P=0.513). The applied CPAP pressure did not correlate with compliance, AHI and ESS. Furthermore, no differences in outcome parameters were noted comparing groups with CPAP pressure <10 and >\\/=10cm H(2) O. Nasal pillows are equally effective in CPAP therapy, but do not generally lead to improved compliance.

von Willebrand disease (VWD) is an inherited bleeding disorder involving a deficiency or abnormal function of a blood clotting protein called von Willebrand factor (VWF). Deficiency of VWF, therefore, shows primarily in organs with small blood vessels such as the skin, the gastrointestinal tract and the uterus. This case report describes management of a patient presenting with type II von Willebrand disease in labor. She had history of lifethreatening hemorrhage from an operation for deviated nasal septum and had a risk of severe postpartum hemorrhage (PPH) within 48 hours of delivery, which was avoided by appropriate planning and timely management.

Full Text Available INTRODUCCIÓN. La nariz constituye el centro estético de la cara y cualquier deformidad en ella afecta de modo importante a la armonía facial. Este estudio tuvo como objetivo caracterizar las experiencias en reconstrucción nasal con colgajo frontal en pacientes con defectos anatómicos de la nariz, como consecuencia fundamentalmente de una cirugía oncológica. MÉTODOS. Se realizó un estudio descriptivo, prospectivo, para caracterizar la experiencia de la reconstrucción nasal con colgajo frontal en pacientes con defectos nasales, atendidos en el Hospital «Hermanos Ameijeiras» y en el Instituto Nacional de Oncología y Radiobiología, entre junio de 1999 y mayo de 2007. RESULTADOS. Destacó que el motivo más frecuente de reconstrucción fue la lesión neoplásica, con igual número de pacientes afectados por carcinoma basocelular y epidermoide. El ala nasal fue la zona más afectada y se presentó recidiva tumoral en 5 pacientes. En todos los casos se pudo crear una cubierta externa al defecto y el diseño oblicuo fue el más utilizado. Se reconstruyó la cubierta interna nasal fundamentalmente con injerto de piel total y el soporte nasal, mayormente con injertos cartilaginosos de la concha auricular. Todos los colgajos frontales se mantuvieron vitales después de su desconexión en el segundo tiempo quirúrgico. El cierre directo de la zona donante fue el más utilizado y en algunos casos se logró con la utilización de expansión tisular. Se realizó un tercer tiempo de remodelación en los pacientes que lo necesitaron. Las complicaciones no afectaron al resultado final de la reconstrucción. CONCLUSIONES. Se demostró la utilidad y vigencia del colgajo frontal en la reconstrucción nasal.ABSTRACT INTRODUCTION.

The purpose of this study was to objectively determine and compare the efficacy and effectiveness of xylitol solution (Xlear Nasal Sprey®) compared with xylometazoline and physiological saline with respect to quality of life (QoL) in patients with nasal congestion. A prospective, randomized study was performed in 42 patients who had nasal obstruction and hypertrophied turbinate mucosa that was refractory to medical treatment. The study population was randomized into 3 groups according to the application of xylometazoline, physiological saline, and xylitol hyperosmolar solution. The efficacy of treatment was evaluated objectively (4-phase rhinomanometry) and subjectively (visual analogue scale VAS.) before and after the application of the nasal solutions. QoL was evaluated by means of Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ). VAS scores and 4-phase rhinomanometry scores were better in the group treated with xylometazoline compared to those treated with xylitol or saline. The xylitol procedure yielded better results than the saline procedure, but differences were not statistically significant in both objective and subjective evaluation methods. For overall QoL, there was a significant improvement from baseline for the xylometazoline and xylitol groups. However, the improvement in the xylometazoline group was significantly greater than that obtained in the xylitol group. Xlear Nasal Spray® is an effective modality in the treatment of nasal congestion and has positive effect on the QoL of patients. Further studies are needed in order to plan an ongoing treatment of Xlear Nasal Sprey® at certain intervals for continuous relief of symptoms and a better and longstanding QoL. © 2014 ARS-AAOA, LLC.

Nasal hyper-reactivity is an increased sensitivity of the nasal mucosa to various nonspecific stimuli. Both allergic rhinitis (AR) and nonallergic rhinitis (NAR) patients can elicit nasal hyper-reactivity symptoms. Differences in the prevalence or type of nasal hyper-reactivity in AR and NAR patients are largely unknown. In this study, we quantitatively and qualitatively assessed nasal hyper-reactivity in AR and NAR. In the first part, an analysis of a prospectively collected database was performed to reveal patient-reported symptoms of hyper-reactivity. In the second part, cold dry air provocation (CDA) was performed as a hyper-reactivity measure in AR and NAR patients and healthy controls, and symptoms scores, nasal secretions and peak nasal inspiratory flow were measured. Comparisons were made between AR and NAR patients in both studies. The database analysis revealed high hyper-reactivity prevalence in AR (63.4%) and NAR (66.9%). There were no differences between AR and NAR in terms of the number or type of hyper-reactivity stimuli. Hyper-reactivity to physical stimuli did not exclude a response to chemical stimuli, or vice versa. CDA provocation resulted in a significant increase in rhinitis symptoms and the amount of nasal secretions in AR and NAR patients, but not in controls. We found no quantitative or qualitative differences in nasal hyper-reactivity between AR and NAR patients. It is not possible to differentiate NAR subpopulations based on physical or chemical stimuli. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The internal nasal valve is the narrowest part of the nasal airway and a common site of inspiratory collapse and obstruction of nasal airflow. Over-the-counter mechanical nasal dilators are an alternative to surgical intervention that attempts to improve airflow through the internal nasal valve. To determine the efficacy of over-the-counter mechanical nasal dilators and classify these products by mechanism. A database of 33 available over-the-counter mechanical nasal dilators was generated via a PubMed search as well as an internet search via Amazon.com and Google, conducted from April 1, 2013, through December 31, 2015. Products determined to be unavailable or discontinued were excluded from the database. Of the devices examined in published literature, efficacy was based on objective measures, such as measured airflow, the cross-sectional area of the nasal valve, and changes in resistance. Measures of reported sleep quality or patient perception were excluded. An analysis of each product's mechanism revealed 4 broad classes: external nasal dilator strips, nasal stents, nasal clips, and septal stimulators. A review demonstrated 5 studies supporting the use of external nasal dilator strips, 4 studies supporting the use of nasal clips, 1 study supporting the use of nasal stents, and no studies supporting the use of septal stimulators. Our findings suggest that external nasal dilator strips and nasal clips effectively relieve obstruction of the internal nasal valve and may be an alternative to surgical intervention in some patients.

Immunophenotype Heterogeneity in Nasal Glomangiopericytoma

Full Text Available Nasal glomangiopericytoma is rare. The immunophenotype is heterogeneous, more frequently smooth-muscle-actin and CD34-positive. We report expression patterns for several vascular-related proteins such as CD99, CD146, Bcl2, and WT1 as well as for treatment-related proteins such as mTOR and EGFR in a nasal glomangiopericytoma. The patient (woman, 86 years presented with a left nasal tumefaction. The resected specimen (1.5-cm showed a glomangiopericytoma. Tumor cells expressed smooth-muscle-actin, CD31, CD34, and progesterone receptor. They also expressed the vascular-cell-related proteins Bcl2, CD99, CD146, and WT1, as well as mTOR and EGFR. Nasal glomangiopericytomas show immunohistochemical heterogeneity for vascular-related markers, suggesting a possible extensive pericytic differentiation. The expression of potential targets for drug treatments such as mTOR and EGFR may impact on the clinical follow-up of these tumors occurring at advanced ages, which may require complex surgery.

Nasotracheal intubation is a widely performed technique to facilitate anesthesia induction during oral, dental, and maxillofacial surgeries. The technique poses several risks not encountered with oropharyngeal intubation, most commonly epistaxis due to nasal mucosal abrasion. The purpose of this study was to test whether the use of the Parker Flex-Tip™ (PFT) nasal endotracheal tube (ETT) with a posterior facing bevel reduces epistaxis when compared with the standard nasal RAE ETT with a leftward facing bevel. Sixty American Society of Anesthesiologists physical status I and II patients undergoing oral or maxillofacial surgery with nasotracheal intubation were recruited. Patients were randomized to either a standard nasal RAE ETT or a PFT nasal ETT. The ETT was thermosoftened and lubricated for both study groups prior to insertion, and the size of the tube was chosen at the discretion of the attending anesthesiologist. The primary outcome was the incidence of epistaxis, with a secondary outcome of epistaxis severity (scored as none, mild, moderate, or severe). An investigator measured both outcomes five minutes after intubation was completed. Mild or moderate epistaxis was experienced by 22 of 30 (73%) patients in the PFT group compared with 21 of 30 (70%) patients in the standard nasal RAE ETT group (absolute risk reduction, 3%; 95% confidence interval, -19 to 25; P = 0.78). There were no occurrences of severe epistaxis in either group. There was no difference in the incidence or severity of epistaxis following nasal intubation using the Parker Flex-Tip nasal ETT when compared with a standard nasal RAE ETT. This trial was registered at ClinicalTrials.gov, identifier: NCT02315677.

In the treatment of nasal deformities associated with cleft lip and palate, deformities of the alar cartilage and upper lateral cartilage are usually repaired. It is very useful if deformities of the nasal cartilage are evaluated preoperatively. We created three-dimensional CT images of soft tissues by the volume rendering method, the nasal cartilage. In 26 patients with unilateral cleft lip and palate, the alar cartilage, upper lateral cartilage, and septal cartilage were evaluated morphologically. As a result, in each case, these cartilages were deviated and deformed. However, the size of both the alar cartilage and the upper lateral cartilage on the cleft side were approximately similar to those on the healthy side. It is suggested that using this method formulated for the imaging of cartilaginous morphology, preoperative planning and follow-up can be performed easily. (author)

Full Text Available INTRODUCCIÓN. La recidiva tumoral es una de las complicaciones más temidas de la evolución oncológica, y además de ensombrecer el pronóstico de vida, causa la pérdida de muchas reconstrucciones y agota las posibilidades quirúrgicas restauradoras. Este estudio tuvo el objetivo de determinar la frecuencia de recidivas, la repercusión sobre la reconstrucción y la evolución médica posterior de pacientes operados de tumoraciones nasales malignas. MÉTODOS. Se realizó un estudio descriptivo retrospectivo, con 20 pacientes operados de tumoraciones nasales malignas, con reconstrucción inmediata con colgajo frontal. Los pacientes procedían del Instituto Nacional de Oncología y Radiobiología (INOR, donde fueron atendidos entre el año 2002 y el 2007. RESULTADOS. Hubo recidivas en 5 pacientes (25 % de la muestra y el 80 % de estas eran un carcinoma epidermoide. Todos los pacientes con recidiva perdieron los tejidos reconstruidos y recibieron tratamiento con radioterapia. Solo se pudo reconstruir nuevamente el defecto de uno de los pacientes; dos de los restantes fallecieron y dos continuaban vivos, sin recurrencia del tumor pero sin posibilidades de reconstrucción. CONCLUSIONES. Teniendo en cuenta la frecuencia de recidivas de los carcinomas epidermoides nasales y de su repercusión, cuando no se cuenta con la técnica histográfica de Mhos, se sugiere posponer la reconstrucción nasal hasta tanto no se realice la confirmación histológica de la exéresis completa del tumor.INTRODUCTION: Tumor relapse is one of the more fearsome complications of the oncologic course and also to obscure the life prognosis, causing the loss of many reconstructions and of exhausting the repairing surgical possibilities.

Sara Diab

2014-01-01

Full Text Available Bronchoscopy is an important diagnostic and therapeutic intervention for a variety of patients displaying pulmonary pathology. The heterogeneity of the patients undergoing bronchoscopy affords a challenge for providing minimal and safe respiratory support during anesthesia. Currently, options are intubation and general anesthesia versus frequently inadequate sedation or local anaesthesia with low flow oxygen through nasal prongs or mouthpiece. The advent of high flow nasal cannula allows the clinician to have a “middle man” that allows high flow oxygen delivery as well as a degree of respiratory support, which in some cases has been noted to be between 3 and 4 cm of continuous positive airway pressure-like effect. There are minimal data analyzing the use of high flow nasal cannula during anesthesia for bronchoscopy. We present a case report of orthotropic lung transplant recipient undergoing diagnostic bronchoscopy whilst being supported with high flow nasal oxygen in the intensive care unit.

Full Text Available In the present study, nasal mucus from patients with leprosy were analyzed by PCR using specific primers for Lsr2 gene of Mycobacterium leprae. The presence of Lsr2 gene in the nasal mucus was detected in 25.80% of patients with paucibacillari leprosy, and 23.07% of contacts. Despite the absence of clinical features in the contact individuals, it was possible to detect the presence of Lsr2 gene in the nasal mucus of these individuals. Therefore, PCR detection of M. leprae targeting Lsr2 gene using nasal mucus samples could contribute to early diagnosis of leprosy.

Motorcycle accidents also play an important role in this affection.

Nasal Cannula Apneic Oxygenation Prevents Desaturation During Endotracheal Intubation: An Integrative Literature Review

Directory of Open Access Journals (Sweden)

Bill R. Christian

2018-02-01

Full Text Available Patients requiring emergency airway management may be at greater risk of acute hypoxemic events because of underlying lung pathology, high metabolic demands, insufficient respiratory drive, obesity, or the inability to protect their airway against aspiration. Emergency tracheal intubation is often required before complete information needed to assess the risk of procedural hypoxia is acquired (i.e., arterial blood gas level, hemoglobin value, or chest radiograph. During pre-oxygenation, administering high-flow nasal oxygen in addition to a non-rebreather face mask can significantly boost the effective inspired oxygen. Similarly, with the apnea created by rapid sequence intubation (RSI procedures, the same high-flow nasal cannula can help maintain or increase oxygen saturation during efforts to secure the tube (oral intubation. Thus, the use of nasal oxygen during pre-oxygenation and continued during apnea can prevent hypoxia before and during intubation, extending safe apnea time, and improve first-pass success attempts. We conducted a literature review of nasal-cannula apneic oxygenation during intubation, focusing on two components: oxygen saturation during intubation, and oxygen desaturation time. We performed an electronic literature search from 1980 to November 2017, using PubMed, Elsevier, ScienceDirect, and EBSCO. We identified 14 studies that pointed toward the benefits of using nasal cannula during emergency intubation.

Use of high-flow nasal cannula in obese patients receiving colonoscopy under intravenous propofol sedation: A case series

Directory of Open Access Journals (Sweden)

Chi Chan Lee

Full Text Available Intravenous sedation during colonoscopy has become the standard practice in the United States given its higher patient satisfaction and procedural quality. This practice is not free of side effects as a significant proportion of patients undergoing this procedure tend to have respiratory depression and desaturation events. Obesity, as it relates to higher levels of body mass index (BMI has a positive correlation with the incidence of hypoxemia. During colonoscopy High flow nasal cannula (HFNC may potentially improve oxygen performance in patients receiving colonoscopy under intravenous sedation. Here we present 3 cases of patients undergoing adjunctive oxygen therapy with HFNC during colonoscopy with intravenous sedation. We found patients to have lower number of desaturation events and were satisfied with their experience.

Full Text Available BackgroundCephalometric analysis is essential for planning treatment in maxillofacial and aesthetic facial surgery. Although photometric analysis of the Korean nose has been attempted in the past, anthropometry of the deeper nasal structures in the same population based on computerized tomography (CT has not been published. We therefore measured three anthropometric parameters of the nose on CT scans in our clinical series of patients.MethodsWe conducted the current retrospective study of a total of 100 patients (n=100 who underwent a CT-guided radiological measurement at our institution during a period ranging from January of 2008 to August of 2010. In these patients, we took three anthropometric measurements: the nasofrontal angle, the pyramidal angle, and the linear distance between the nasion and the tip of the nasal bone.ResultsThe mean nasofrontal angle was 131.14° in the male patients and 140.70° in the female patients. The mean linear distance between the nasion and the tip of the nasal bone was 21.28 mm and 18.02 mm, respectively. The mean nasal pyramidal angle was 112.89° and 103.25° at the level of the nasal root, 117.49° and 115.60° at the middle level of the nasal bone, and 127.99° and 125.04° at the level of the tip of the nasal bone, respectively.ConclusionsIn conclusion, our data will be helpful in the preparation of silicone implants for augmentation and/or corrective rhinoplasty in ethnic Korean people.

Full Text Available Aim: Nasal polyps (NPs are the most common reason for nasal obstruction, with a prevalence of 1-4%. Although the etiology is not clearly known, chronic infections and mechanical, immunological, and biochemical factors can play a role in the etiology. Recently, mean platelet volume (MPV was recognized as a simple inflammatory marker in the inflammatory disease. In this study, we aimed to evaluate platelet (PLT and MPV in patients with NPs. Material and Method: This study included 80 histopathologically proven patients with NPs and 80 age- and sex-matched healthy subjects as controls. The Lund-Mackay staging system was used to evalute paranasal sinus CT scans, in patients with NPs, and paranasal sinus CT scores were recorded. Values of MPV, platelet (PLT, platelet crit (PCT and platelet distribution width (PDW were assessed in NP and control groups. Results: MPV and PLT values were found to be low in patients with NPs, at 8.57±1.62 fL and 259.99±62.03 x103/µL, respectively, compared with the control groups, at 8.79±1.49fL and 270.29±61.82 x103/µL. These findings were not statistically significant. PDW values were found to be slightly high in patients with NPs, at 17.1±1.36 fL, compared with the control group, at 16.78±1.04 fL (p=0.075. But PCT values were found to be low in patients with NPs, at 0.21±0.065, compared with the control group, at 0.23±0.069 (p=0.044. This finding was statistically significant. Discussion: In our study, the MPV and PLT values were lower in patients with NPs, but the difference was not statistically significant. According to our findings, the use of MPV as an inflammation marker in patients with NPs does not seem to be reliable.

Characteristics of nasal-associated lymphoid tissue (NALT) and nasal absorption capacity in chicken.

2013-01-01

As the main mucosal immune inductive site of nasal cavity, nasal-associated lymphoid tissue (NALT) plays an important role in both antigen recognition and immune activation after intranasal immunization. However, the efficiency of intranasal vaccines is commonly restricted by the insufficient intake of antigen by the nasal mucosa, resulting from the nasal mucosal barrier and the nasal mucociliary clearance. The distribution of NALT and the characteristic of nasal cavity have already been described in humans and many laboratory rodents, while data about poultry are scarce. For this purpose, histological sections of the chicken nasal cavities were used to examine the anatomical structure and histological characteristics of nasal cavity. Besides, the absorptive capacity of chicken nasal mucosa was also studied using the materials with different particle size. Results showed that the NALT of chicken was located on the bottom of nasal septum and both sides of choanal cleft, which mainly consisted of second lymphoid follicle. A large number of lymphocytes were distributed under the mucosal epithelium of inferior nasal meatus. In addition, there were also diffuse lymphoid tissues located under the epithelium of the concha nasalis media and the walls of nasal cavity. The results of absorption experiment showed that the chicken nasal mucosa was capable to absorb trypan blue, OVA, and fluorescent latex particles. Inactivated avian influenza virus (IAIV) could be taken up by chicken nasal mucosa except for the stratified squamous epithelium sites located on the forepart of nasal cavity. The intake of IAIV by NALT was greater than that of the nasal mucosa covering on non-lymphoid tissue, which could be further enhanced after intranasal inoculation combined with sodium cholate or CpG DNA. The study on NALT and nasal absorptive capacity will be benefit for further understanding of immune mechanisms after nasal vaccination and development of nasal vaccines for poultry.

The traditional method of management of posterior epistaxis has been with anteroposterior nasal packing. Apart from the high failure rate of 26–50% reported in various series, nasal packing is associated with marked discomfort and several complications. In order to avoid nasal packing, we started doing endoscopic cauterization in cases of posterior epistaxis. A total of 23 patients with posterior epistaxis were subjected to nasal endoscopy with the intent to stop bleeding by cauterization of ...

Full Text Available   Introduction: Adequate pain control is an important consideration in the post-surgical management of patients. Local nerve blockade added to general anesthesia can provide excellent pain control during and after most nasal surgical procedures. The aim of this study was to determine the combined effect of local anesthetic drugs with corticosteroids in nasal surgery. Materials and Methods: In this double-blind clinical study, 60 patients who underwent different nasal surgical procedures were matched and divided into two equal groups. Bilateral local nerve blockade was used in both groups. Bupivacaine or bupivacaine plus dexamethasone was administered by injection (groups B and B+D, respectively. Postoperative visual analog scale (VAS pain values and the need for oral/intramuscular analgesic treatment in the first 24 h were recorded in all patients. Results: Thirty-eight male (63.3% and 22 female (36.7% patients were included in this study, with a mean age of 28.3 ± 8.2 years. At 1, 2, 4, 6, and 12 h post surgery, VAS pain values were significantly lower in the B+D group than in the B group. The analgesic requirement was significantly lower in the B+D group compared with the B group. No relevant complications were seen during surgery or postoperative hospitalization. Conclusion: This study demonstrates the positive effect of a combination of a dexamethasone with a bupivacaine in reducing pain and the need for analgesic drugs after different nasal surgeries. No acute or short-term post-surgical complications were observed in this study.

Full Text Available Introduction: Nasal polyposis is an inflammatory condition of unknown etiology. Recently concerns regarding gastroesophageal reflux or helicobacter pylori as a possible pathologic cause of nasal polyps have been increasing. The present study was planned to investigate the presence of helicobacter pylori in nasal polyps. Materials and Methods: This case-control study was undertaken enrolling 37 patients with nasal polyps who had undergone nasal endoscopic sinus surgery and 38 control subjects. Biopsy specimens of nasal polyps and inferior turbinates were assessed by rapid urease test. Blood samples of both study and control subjects were evaluated for anti H.pylori IgG by ELISA. H. pylori status was regarded positive, if both tests were positive. Results: Seropositivity was more common in the patients with nasal polyps (66.2% than control subjects (36.8% (P

Full Text Available Introduction: Nasal provocation testing involves an allergen-specific local reaction of the nasal mucosa to the administered allergen. Aim: To determine the most objective nasal occlusion assessment technique that could be used in nasal provocation testing. Material and methods : A total of 60 subjects, including 30 patients diagnosed with allergy to common environmental allergens and 30 healthy subjects were enrolled into the study. The method used in the study was a nasal provocation test with an allergen, with a standard dose of a control solution and an allergen (5,000 SBU/ml administered using a calibrated atomizer into both nostrils at room temperature. Early-phase nasal mucosa response in the early phase of the allergic reaction was assessed via acoustic rhinometry, optical rhinometry, nitric oxide in nasal air, and tryptase levels in the nasal lavage fluid. Results : In estimating the homogeneity of the average values, the Levene’s test was used and receiver operating characteristic curves were plotted for all the methods used for assessing the nasal provocation test with an allergen. Statistically significant results were defined for p < 0.05. Of all the objective assessment techniques, the most sensitive and characteristic ones were the optical rhinometry techniques (specificity = 1, sensitivity = 1, AUC = 1, PPV = 1, NPV = 1. Conclusions : The techniques used showed significant differences between the group of patients with allergic rhinitis and the control group. Of all the objective assessment techniques, those most sensitive and characteristic were the optical rhinometry.

Full Text Available Background: Airway management in maxillofacial injuries presents with a unique set of problems. Compromised airway is still a challenge to the anesthesiologist in spite of all modalities available. Maxillofacial injuries are the result of high-velocity trauma arising from road traffic accidents, sport injuries, falls and gunshot wounds. Any flaw in airway management may lead to grave morbidity and mortality in prehospital or hospital settings and as well as for reconstruction of fractures subsequently. Methods: One hundred and seventy-seven patients of maxillofacial injuries, operated over a period of one and half years during July 2008 to December 2009 in Al-Nahdha hospital were reviewed. All patients were reviewed in depth with age related type of injury, etiology and techniques of difficult airway management. Results: The major etiology of injuries were road traffic accidents (67% followed by sport (15% and fall (15%. Majority of patients were young in the age group of 11-30 years (71 %. Fracture mandible (53% was the most common injury, followed by fracture maxilla (21%, fracture zygoma (19% and pan-facial fractures (6%. Maxillofacial injuries compromise mask ventilation and difficult airway due to facial fractures, tissue edema and deranged anatomy. Shared airway with the surgeon needs special attention due to restrictions imposed during surgery. Several methods available for securing the airway, both decision-making and performance, are important in such circumstances. Airway secured by nasal intubation with direct visualization of vocal cords was the most common (57%, followed by oral intubation (17%. Other methods like tracheostomy and blind nasal intubation was avoided by fiberoptic bronchoscopic nasal intubation in 26% of patients. Conclusion: The results of this study indicated that surgically securing the airway by tracheostomy should be revised compared to other available methods. In the era of rigid fixation of fractures and the

We sought to evaluate the short-term efficacy of radiofrequency volumetric tissue reduction (RFVTR) in treatment of inferior turbinate hypertrophy (TH) as measured by expiratory nasal sound spectra. In our study, we aimed to investigate the Odiosoft-rhino (OR) as a new diagnostic method to evaluate the nasal airflow of patients before and after RFVTR. In this study, we have analyzed and recorded the expiratory nasal sound in patients with inferior TH before and after RFVTR. This analysis includes the time expanded waveform, the spectral analysis with time averaged fast Fourier transform (FFT), and the waveform analysis of nasal sound. We found an increase in sound intensity at high frequency (Hf) in the sound analyses of the patients before RFVTR and a decrease in sound intensity at Hf was found in patients after RFVTR. This study indicates that RFVTR is an effective procedure to improve nasal airflow in the patients with nasal obstruction with inferior TH. We found significant decreases in the sound intensity level at Hf in the sound spectra after RFVTR. The OR results from the 2000- to 4000-Hz frequency (Hf) interval may be more useful in assessing patients with nasal obstruction than other frequency intervals. OR may be used as a noninvasive diagnostic tool to evaluate the nasal airflow.

Full Text Available Introduction A significant portion of patients treated in emergency departments have nasal fracture. It is important that the otolaryngologist know how to treat such damage. Objectives To evaluate the effectiveness of nasal fracture reduction under local anesthesia and tolerance to the procedure. Methods Twenty-four patients treated in the emergency department with closed reduction under local anesthesia were prospectively followed. Epidemiologic information and data regarding pain and complications during the management were noted. The degree of satisfaction was researched by visual analog scale. Results The majority of patients were male (75%, and the most common cause of injury was motor vehicle accident. We found a significant association between time to reduction and referred pain during the procedure. In patients in whom the procedure was delayed (over 3 days, there was less pain, and those who bled during the procedure had a shorter average time to reduction than the group of patients who did not bleed. Most patients were very satisfied, with more than 95% of these willing to undergo the same process again, if necessary. Conclusions The closed approach in the clinic under local anesthesia was effective and safe in restoration of the nose.

Bilateral cleft lip nasal deformity

Singh Arun

2009-01-01

Full Text Available Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it′s management both at the time of cleft lip repair

To evaluate the CT findings of malignant nasal cavity tumors. Retrospective analysis was performed on 20 patients with pathologically-proven malignant nasal cavity tumors. Using CT, we analysed their location, extent of bone destruction and of involvement of adjacent structures, and enhancing pattern. A total of 20 cases included nine squamous cell carcinomas, three olfactory neuroblastomas, three lymphomas, two polymorphic reticulosis, one adenoid cystic carcinoma, one undifferentiated carcinoma and one metastasis from renal cell carcinoma. All cases except one adenoid cystic carcinoma and one squamous cell carcinoma revealed bone destruction or erosion. Aggressive bone destruction and irregular enhancement were seen in eight cases of squamous cell carcinoma, seven cases of which showed involvement of the adjacent paranasal sinuses, nasopharynx, and orbit. Olfactory neuroblastomas were centered in the superior nasal cavity and the adjacent ethmoid sinus, and erosion or destruction of the cribriform plate had occurred. Lymphomas showed bilateral involvement, with uniform contrast enhancement. Polymorphic reticuloses showed perforation or erosion of the nasal septum, with bilateral involvement of the nasal cavity. The location, presence of bone destruction, involvement of adjacent structures, and enhancement pattern of tumor on CT can be helpful for the differential diagnosis of malignant nasal cavity tumors

Conclusion: Compared to conventional methods, CANS is more accurate for detecting NBF. We recommend its use as an alternative tool for diagnosing a nasal fracture. Because the tube technique balances pressure between the nasopharynx and middle ear during swallowing, patient comfort is enhanced. Application of these modifications can improve accuracy in diagnosing NBF and can improve the quality of NBF treatment.

To perform the translation, cross-cultural adaptation, and validation of the Sino-Nasal Outcome Test-22 (SNOT-22) questionnaire to the Hebrew language. A single-center prospective cross-sectional study. Seventy-three chronic rhinosinusitis (CRS) patients and 73 patients without sinonasal disease filled the Hebrew version of the SNOT-22 questionnaire. Fifty-one CRS patients underwent endoscopic sinus surgery, out of which 28 filled a postoperative questionnaire. Seventy-three healthy volunteers without sinonasal disease also answered the questionnaire. Internal consistency, test-retest reproducibility, validity, and responsiveness of the questionnaire were evaluated. Questionnaire reliability was excellent, with a high internal consistency (Cronbach's alpha coefficient, 0.91-0.936) and test-retest reproducibility (Spearman's coefficient, 0.962). Mean scores for the preoperative, postoperative, and control groups were 50.44, 29.64, and 13.15, respectively (P < .0001 for CRS vs controls, P < .001 for preoperative vs postoperative), showing validity and responsiveness of the questionnaire.

To describe the characteristics of CT findings in nasal lymphoma. We retrospectively reviewed CT findings and pathologic findings of eight patients (six males and two females) aged between 24 and 68 years with pathologically-proven nasal lymphoma. We analyzed mass location, laterality, size, margin, mass effect, adjacent bony change and contrast enhancement pattern. All eight cases were non-Hodgkin's lymphoma, intermediate grade, diffuse large cell type. Seven cases were B-cell type and one was T-cell. In all cases, tumors were located in the medial wall of the inferior turbinate. In four cases, they were also found in the anterior ethmoidal sinus, and in one case, in the nasal septum. The mean size of the main mass was 3.3cm. In seven cases, tumors were unilateral (one on the right; six on the left), and in the remaining case, bilateral. In six cases tumor margin was smooth and in two cases focal nodularity was seen. In two cases there was no bony change, and in four, there was mucosal thickening along the nasal septum; in one of these four, minimal bony erosion was also found. In the other two cases, bony destruction was seen, and tumors were very large(7cm in diameter) or bilterally located. In three cases, the nasal septum was displaced by the mass. In all cases with bony change, the nasal septum was involved. All tumors were homogeneously well enhanced after IV contrast administration. The main CT findings of nasal non-Hodgkin's lymphoma were smooth margin, unilateral location (mainly in the medial wall of the inferior turbinate and growing to the medial side without bony destruction) mucosal thickening along the nasal septum and clear homogeneous enhancement after IV contrast administration. These characteristics will help diagnosis, help deter-mine the appropriate region for radiation and other appropriate therapy, and facilitate prognosis in patients with nasal non-Hodgkin's lymphoma.

Full Text Available Objective. To investigate whether high-flow nasal cannula (HFNC oxygen therapy is superior to conventional oxygen therapy for reducing hypoxemia and postoperative pulmonary complications (PPC in patients with thoracoscopic lobectomy after extubation. Methods. Patients with intermediate to high risk for PPC were enrolled in this study. Subjects were randomly assigned to HFNC group (HFNCG or conventional oxygen group (COG following extubation. Arterial blood samples were collected after extubation at 1, 2, 6, 12, 24, 48, and 72 h. Patients with postoperative hypoxemia and PPC were recorded. Adverse events were also documented. Results. Totally 110 patients were randomly assigned to HFNCG (n=56 and COG (n=54. The occurrence rate of hypoxemia in COG was twice more than that in HFNCG (29.62% versus 12.51%, P0.05. Adverse effects as throat and nasal pain occurred more frequently in COG. Conclusions. HFNC application improves oxygenation and reduces the risk of reintubation following thoracoscopic lobectomy but cannot decrease the incidence of PPC.

Epidemiological studies show female predominance in the prevalence of non- allergic rhinitis (NAR) and local allergic rhinitis (LAR). Experimental studies show female patients with allergic rhinitis (AR) demonstrate higher levels of sensitivity to irritants and airway hyperresponsiveness than males. Bronchial asthma shows female predominance in post-puberty patients, and gender interaction with severe asthma endotypes. Fibromyalgia, chronic fatigue syndrome, migraine and chronic cough, syndromes, which are commonly related to neurokinin substance P (SP) in the literature, also show strong female predominance. Studies have demonstrated that sex hormones, primarily oestrogens, affect mast cell activation. Mast cell proteases can amplify neurogenic inflammatory responses including the release of SP. Based on human epidemiological data and animal experimental data we hypothesized that female patients have different interaction between mast cell activation and neurogenic inflammation, i.e. substance P release, resulting in a different nasal symptom profile. To test the hypothesis we performed allergen and non-specific nasal challenges in patients with seasonal allergic rhinitis (SAR) out of season and looked for gender differences in subjective and objective responses. The interaction between subjective and objective reactivity was evaluated through the comparison of subjective symptom scores, concentrations of neurokinin substance P (SP) and cellular markers in nasal lavages after low doses of nasal allergen challenges. Female allergic subjects tended to have higher substance P (SP) concentrations both before and after non-specific challenges. The difference between post-allergen and post - hypertonic saline (HTS) challenge was highly significant in female patients (p = 0.001), while insignificant in male subjects (p = 0.14). Female patients had significantly stronger burning sensation after HTS challenge than male. These data indicate difference in the

Full Text Available Introduction: The complexity of the nasal tip structures and the impact of surgical maneuvers make the prediction of the final outcome very difficult. Therefore, no single technique is enough to correct the several anatomical presentations, and adequate preoperative planning represents the basis of rhinoplasty. Objective: To present results of rhinoplasty, through the gradual surgical approach to nasal tip definition based on anatomical features, and to evaluate the degree of patient satisfaction after the surgical procedure. Methods: Longitudinal retrospective cohort study of the medical charts of 533 patients of both genders who underwent rhinoplasty from January of 2005 to January of 2012 was performed. Cases were allocated into seven groups: (1 no surgery on nasal tip; (2 interdomal breakup; (3 cephalic trim; (4 domal suture; (5 shield-shaped graft; (6 vertical dome division; (7 replacement of lower lateral cartilages. Results: Group 4 was the most prevalent. The satisfaction rate was 96% and revision surgery occurred in 4% of cases. Conclusion: The protocol used allowed the implementation of a gradual surgical approach to nasal tip definition with the nasal anatomical characteristics, high rate of patient satisfaction with the surgical outcome, and low rate of revision.

Objective: To evaluate the effects of nasal non-Hodgkin's lymphoma(N-NHL) treated with chemotherapy alone, radiotherapy alone, chemotherapy plus radiotherapy and autologous peripheral blood stem cell transplantation(APBSCT) combined with total body irradiation(TBI); and to analyze the impact factors of prognosis. Methods: 135 patients were treated between 1980 and 2000. All were confirmed by histopathology as N- NHL, including 122 T cell in origin, 12 B cell and 1 NK cell in origin. The main radiotherapy portal was set in front of the nose with a spade-like protrusion, supplement with a portal next to the ear on one side or both sides. Combined portal in facial cervical area was first used when there was invasion of the oropharynx. The median dose to the nasal cavity was 56.0 Gy with a range of 35.2 to 75.5 Gy, with added 30 Gy to the primary lesion in two patients. Six patients received TBI combined with APBSCT, with 8 Gy in the TBI group. Chemotherapy, given before or during after radiotherapy or alone, consisted of 2-6 cycles of COP, COPP, COMP, CHOP or COBDP. Prognostic factors were analyzed with Cox model. Results: The local control rate was 12%, 69%, 76% and 83% in chemotherapy alone, radiotherapy alone, chemotherapy plus radiotherapy and APBSCT combined with TBI, respectively (P=0.057). The 5-year survival rate was 9%, 52%, 63% and 83%, respectively (P=0.032). Multi- factor analysis showed that tumor extension and treatment methods were the most important prognostic factors be- sides Ann-Arbor stage, but gender, pathology, age and symptoms had little effect on prognosis. Conclusions: Chemotherapy plus radiotherapy group achieves a better survival rate than radiotherapy alone. It is helpful to evaluate prognosis to make more detail subareas on basis of local extensions in Ann Arbor staging system. For some N- NHL patients with good financial condition, APBSCT combined with TBI is a good choice. (authors)

Holmberg, K.; Bake, B.; Pipkorn, U.

1988-01-01

The nasal mucosal blood flow in patients with allergic rhinitis was determined at nasal allergen challenges with the 133 Xenon washout method. Determinations were made in 12 subjects before and 15 minutes after challenge with diluent and increasing doses of allergen. The time course was followed in eight subjects by means of repeated measurements during 1 hour after a single allergen dose. Finally, the blood flow was measured after unilateral allergen challenge in the contralateral nasal cavity. A dose-dependent decrease in blood flow was found after nasal challenge with increasing doses of allergens, whereas challenge with diluent alone did not induce any changes. The highest allergen dose, which also induced pronounced nasal symptoms, resulted in a decrease in blood flow of 25% (p less than 0.001). The time-course study demonstrated a maximum decrease in blood flow 10 to 20 minutes after challenge and then a gradual return to baseline. Unilateral allergen challenge resulted in a decrease in blood flow in the contralateral, unchallenged nasal cavity, suggesting that part of the allergen-induced changes in blood flow were reflex mediated

Full Text Available Summary:. It is difficult to put forward a strategy for the treatment of nasal clefts due to the rarity and diversity of anatomical aberrations of these cases contrary to the common nasal affection in cleft lip and palate patients, which differ in severity rather than differing in the morbid anatomy. This simple strategy for correction of these nasal clefts will hopefully help surgeons to achieve better results. In the mean time I intended to describe the morbid anatomy of these cases by choosing examples of each morbid anatomy.

Nasal polyposis is often found in patients with cystic fibrosis. To assess the incidence of nasal polyposis, the response to medical treatment, recurrence and the need for surgical intervention in children and adolescents with cystic fibrosis during a three-year follow-up. Clinical symptoms (pulmonary, pancreatic insufficiency, malnutrition, nasal obstruction), two positive sweat chloride tests, and genotype findings in 23 patients with cystic fibrosis were analyzed. All patients underwent nasal endoscopy every 12 months from January 2005 to December 2007, to assess the presence and grade of Nasal Polyps. Nasal polyposis, when present, were treated with topical corticosteroids for 6-12 months, with progress being evaluated within the 3 years of follow-up. In the first evaluation, nasal polyposis was diagnosed in 30.43% of patients (3 bilateral and 4 unilateral), recurrent pneumonia in 82.6%, pancreatic insufficiency in 87%, and malnutrition in 74%. The presence of nasal polyposis was not associated with chloride values in the sweat, genotype, clinical signs of severity of cystic fibrosis, or nasal symptoms. In the three-year period of follow up, 13 patients (56.52%) had at least one event of polyposis, with the youngest being diagnosed at 32 months of age. Only one patient underwent surgery (polypectomy), and there was one diagnosis of nasopharyngeal carcinoma. The study showed a high incidence of nasal polyposis. Monitoring through routine endoscopy in patients with cystic fibrosis, even in the absence of nasal symptoms, is highly recommended. The therapy with topical corticosteroids achieved good results. Thus, an interaction between pediatricians and otolaryngologists is necessary. Copyright © 2016 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is often comorbid with asthma and resistant to therapeutic interventions. We recently reported that excessive fibrin deposition caused by impairment of fibrinolysis might play pivotal role in forming nasal polyp. Nattokinase (NK), a serine protease produced by Bacillus subtilis, has been reported to be a strong fibrinolytic enzyme. NK could be a promising drug candidate for use in the treatment of both CRSwNP and asthma. The objective of this study was to investigate the effects of NK on nasal polyp tissues from patients with CRSwNP. The nasal discharge from patients with CRSwNP and sputum from subjects with asthma were also used to investigate whether NK influences the viscosity of mucus. To examine the effects on NK on nasal polyp tissues, pieces of nasal polyps were incubated either with saline or NK (10-1000 FU/ml) at 37 °C for 24 h. We assessed the presence of fibrin in nasal polyp tissue incubated with NK by means of immunohistochemistry. To examine the effects of NK on nasal discharge and sputum from patients with CRSwNP and asthma, respectively, were incubated with NK solution at 37 °C for 1 h. NK effectively shrinks the nasal polyp tissue through fibrin degradation. We also found that the viscosity of the nasal discharge and sputum from patients with CRSwNP and asthma, respectively, was significantly reduced by incubation with NK solution. NK may be an effective alternative therapeutic option in patients with CRSwNP and comorbid asthma by causing fibrin degradation. Copyright © 2017 Japanese Society of Allergology.

1988-12-01

The size and configuration of the nasal airways of humans change with time as a result of the normal process of congestion/decongestion of the erectile tissue of the nasal mucosa. To determine the extent to which airway areas change in vivo, we used magnetic resonance imaging (MRI) to quantitate both the cross-sectional area and perimeter of coronal sections of the entire nasal airway of a human subject. Changes in airway size or patency were indexed to measured changes in unilateral nasal airway resistance determined by posterior rhino manometry. The results of this study in which two MRI scans were performed for presumed left-side patency and two for right-side patency, showed that changes in nasal airway resistance were difficult to ascribe to systematic changes In the sizes of the airways.

In this study, the effects of nasal drug delivery device and the spray nozzle orientation on sprayed droplets deposition in a realistic human nasal cavity were numerically studied. Prior to performing the numerical investigation, an in-house designed automated actuation system representing mean adults actuation force was developed to produce realistic spray plume. Then, the spray plume development was filmed by high speed photography system, and spray characteristics such as spray cone angle, break-up length, and average droplet velocity were obtained through off-line image analysis. Continuing studies utilizing those experimental data as boundary conditions were applied in the following numerical spray simulations using a commercially available nasal spray device, which was inserted into a realistic adult nasal passage with external facial features. Through varying the particle releasing direction, the deposition fractions of selected particle sizes on the main nasal passage for targeted drug delivery were compared. The results demonstrated that the middle spray direction showed superior spray efficiency compared with upper or lower directions, and the 10µm agents were the most suitable particle size as the majority of sprayed agents can be delivered to the targeted area, the main passage. This study elaborates a comprehensive approach to better understand nasal spray mechanism and evaluate its performance for existing nasal delivery practices. Results of this study can assist the pharmaceutical industry to improve the current design of nasal drug delivery device and ultimately benefit more patients through optimized medications delivery.

Objective The aim of the present study was to use facial analysis to determine the effects of rapid maxillary expansion (RME) on nasal morphology in children in the stages of primary and mixed dentition, with posterior cross-bite. Material and Methods Facial photographs (front view and profile) of 60 patients in the pre-expansion period, immediate post-expansion period and one year following rapid maxillary expansion with a Haas appliance were evaluated on 2 occasions by 3 experienced orthodontists independently, with a 2-week interval between evaluations. The examiners were instructed to assess nasal morphology and had no knowledge regarding the content of the study. Intraexaminer and interexaminer agreement (assessed using the Kappa statistic) was acceptable. Results From the analysis of the mode of the examiners' findings, no alterations in nasal morphology occurred regarding the following aspects: dorsum of nose, alar base, nasal width of middle third and nasal base. Alterations were only detected in the nasolabial angle in 1.64% of the patients between the pre-expansion and immediate post-expansion photographs. In 4.92% of the patients between the immediate post-expansion period and 1 year following expansion; and in 6.56% of the patients between the pre-expansion period and one year following expansion. Conclusion RME performed on children in stages of primary and mixed dentition did not have any impact on nasal morphology, as assessed using facial analysis. PMID:21986660

Trigeminal sensation (TS) within the nasal cavity is important for the perception of nasal airflow. The objective of this study is to examine whether impaired TS contributes to the sensation of nasal obstruction in patients with chronic rhinosinusitis (CRS). Prospective case-control study conducted in a tertiary referral rhinology clinic. Cases consisted of CRS patients with subjective nasal obstruction, not previously treated with oral corticoids. Controls consisted of patients without CRS. Neither group demonstrated obvious anatomical obstructions. Both groups underwent peak nasal inspiratory flows (PNIF), olfactory testing (quick eight-item odor identification test), and trigeminal testing (lateralization task using eucalyptol and odorless solvent). A total of 28 subjects (14 CRS patients and 14 controls) were recruited. Analyses revealed no statistical differences in age (P = .93), gender (P = .47), or PNIF (P = .82) between the two groups, but they differed in Lund-Mackay scores (P sensation of nasal obstruction in CRS. 3b.

Heated humidification can reduce nasal symptoms caused by continuous positive airway pressure (CPAP) treatment, but its routine use has not been studied over the medium term in a randomized controlled trial. The aim of this study is to determine if heated humidification would reduce nasal symptoms and improve adherence with CPAP treatment in all patients with sleep apnoea irrespective of whether they had nasal symptoms initially. A randomized, parallel group design. Patients were treated for 3 months with a Fisher & Paykel HC201 pump with built-in heated humidification, or with the heater disabled and without water. Adherence was measured with a timer built into the pumps. Nasal symptoms were measured with a 10-cm visual analogue scale. There were 25 in the humidification group and 29 in the non-humidification group. After 12 weeks mean (standard deviation) adherence with CPAP was 4.7 (2.4) and 4.5 (2.2) hours per night respectively. Nasal symptoms that were reduced were nose blocked* 6 (12), 18 (26); sneezing* 4 (8), 15 (25); dry nose* 8 (12), 24 (33); stuffy nose* 7 (14), 22(31); dry mouth* 13 (18), 33(36); and runny nose* 6 (17), 14 (29).

Kundoor, Vipra; Dalby, Richard N

2011-08-01

To systematically evaluate the effect of formulation- and administration-related variables on nasal spray deposition using a nasal cast. Deposition pattern was assessed by uniformly coating a transparent nose model with Sar-Gel®, which changes from white to purple on contact with water. Sprays were subsequently discharged into the cast, which was then digitally photographed. Images were quantified using Adobe® Photoshop. The effects of formulation viscosity (which influences droplet size), simulated administration techniques (head orientation, spray administration angle, spray nozzle insertion depth), spray pump design and metering volume on nasal deposition pattern were investigated. There was a significant decrease in the deposition area associated with sprays of increasing viscosity. This appeared to be mediated by an increase in droplet size and a narrowing of the spray plume. Administration techniques and nasal spray pump design also had a significant effect on the deposition pattern. This simple color-based method provides quantitative estimates of the effects that different formulation and administration variables may have on the nasal deposition area, and provides a rational basis on which manufacturers of nasal sprays can base their patient instructions or post approval changes when it is impractical to optimize these using a clinical study.

It was found that this could be related to the stage of the nasal cycle before the provocation. objective. To discover whether the stage of the nasal cycle is decisive for asymmetry in congestive response observed during bilateral allergen nasal provocation. methods. Two bilateral nasal allergen provocations were performed in a group of 26 pollen-sensitive volunteers. Acoustic rhinometry measurements were taken during the nasal cycle, and then after the provocation. A cross-sectional area at the level of the inferior turbinate (CSA-2 was measured. Consecutive challenges were performed in the opposite phase of the nasal cycle: the side which had been wide just before the first challenge, was narrow before the second provocation. results. Asymmetry in CSA-2 reduction between the nasal passages was observed in most cases. Significant difference was observed between mean CSA-2 reduction rate (reactivity of the side that responded with greater congestion, and the opposite side. No significant difference was found in mean CSA-2 reduction rate between the side which was narrow, and the side which was wide before provocation. conclusions. Asymmetry of congestive response during bilateral nasal allergen provocation is not dependent on the stage of the nasal cycle preceding the challenge.

The contribution of ectopic lymphoid tissues (eLTs) to local immunoglobulin hyperproduction in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) is unclear. We sought to explore the cellular basis, formation mechanisms, and function of eLTs in patients with CRSwNP. We graded lymphoid aggregations in sinonasal mucosa and histologically studied their structures. The expression of lymphorganogenic factors and molecules required for immunoglobulin production was measured by using real-time PCR, and their localization was analyzed by means of immunohistochemistry and immunofluorescence. The phenotype of follicular helper T cells was analyzed by performing flow cytometry. Immunoglobulin levels were quantified by using the Bio-Plex assay or ImmunoCAP system. Nasal tissue explants were challenged ex vivo with Dermatophagoides pteronyssinus group 1 (Der p 1), and the expression of Iε-Cμ and Iε-Cγ circle transcripts was detected by using seminested PCR. Increased formation of eLTs with germinal center-like structures was discovered in patients with eosinophilic (20.69%) and noneosinophilic (17.31%) CRSwNP compared with that in patients with chronic rhinosinusitis without nasal polyps (5.66%) and control subjects (3.70%). The presence of eLTs was associated with increased expression of lymphorganogenic and inflammatory chemokines and cytokines, as well as their receptors. The expression of molecules required for immunoglobulin production, generation of follicular helper T cells, and production of IgE in eosinophilic polyps and IgG and IgA in both eosinophilic and noneosinophilic polyps were predominantly upregulated in patients with eLTs. After Der p 1 challenge ex vivo, Iε-Cμ transcript was detected only in eosinophilic polyps with eLTs but not in polyps without eLTs and noneosinophilic polyps. eLTs might support local immunoglobulin production and therefore significantly contribute to the development of CRSwNP.

Spindle Cell Carcinoma of Nasal Cavity- A Case Report

Science.gov (United States)

Mittal, Abhishek; Nagpal, Tapan

2016-01-01

Spindle Cell Carcinoma (SpCC), also known as Sarcomatoid Carcinoma, is a rare and peculiar biphasic malignant neoplasm that occurs mainly in the upper aero-digestive tract, mostly in larynx. SCC accounts for 3% of all squamous cell carcinomas (SCCs) in the head and neck region. It is a rare variant of SCC which shows spindled or pleomorphic tumour cells simulating a true sarcoma. We present a case report of SpCC nasal cavity in a 50-year-old female patient, presented with intermittent epistaxis from left nasal cavity. On physical examination, the patient had an ulcero-exophytic type of mass in the left nasal cavity and a smooth bulge on the left side of anterior hard palate. Patient underwent excision of nasal mass along with partial palatectomy by facial degloving approach and reconstruction of palate with naso-labial flap. The postoperative histopathological report showed SCC. Surgery forms the mainstay of treatment. Radiotherapy and Chemotherapy is warranted in order to improve treatment results. As only few cases have been reported, we report a case of this rare entity to contribute for better understanding and awareness of this rare malignancy. PMID:27190843

2016-09-01

Full Text Available Objectives: The accessory middle turbinate, a rare anatomical variation of the nasal cavity, have been systematically studied in adults. Presence of accessory middle turbinate and its clinical significance in a child has not been reported. We describe clinical appearance and radiologic features of accessory middle turbinate in a child. Methods: Retrospective chart review. Results: A 3-year-old boy presented to the otolaryngology clinic for evaluation of recurrent epistaxis. Anterior rhinoscopy revealed moist nasal mucosa without inflammation and bilateral prominent blood vessels on the anterior nasal septum. Nasal endoscopy showed turbinate like protuberances in bilateral middle meatus. CT images documented accessory middle turbinate in the bilateral nasal cavity. Conclusion: Otolaryngologists should be cognizant of anatomical variations of middle turbinate to achieve correct diagnosis and avoid potential complications during surgical management.

New CFD tools to evaluate nasal airflow.

Computational fluid dynamics (CFD) is a mathematical tool to analyse airflow. As currently CFD is not a usual tool for rhinologists, a group of engineers in collaboration with experts in Rhinology have developed a very intuitive CFD software. The program MECOMLAND ® only required snapshots from the patient's cross-sectional (tomographic) images, being the output those results originated by CFD, such as airflow distributions, velocity profiles, pressure, temperature, or wall shear stress. This is useful complementary information to cover diagnosis, prognosis, or follow-up of nasal pathologies based on quantitative magnitudes linked to airflow. In addition, the user-friendly environment NOSELAND ® helps the medical assessment significantly in the post-processing phase with dynamic reports using a 3D endoscopic view. Specialists in Rhinology have been asked for a more intuitive, simple, powerful CFD software to offer more quality and precision in their work to evaluate the nasal airflow. We present MECOMLAND ® and NOSELAND ® which have all the expected characteristics to fulfil this demand and offer a proper assessment with the maximum of quality plus safety for the patient. These programs represent a non-invasive, low-cost (as the CT scan is already performed in every patient) alternative for the functional study of the difficult rhinologic case. To validate the software, we studied two groups of patients from the Ear Nose Throat clinic, a first group with normal noses and a second group presenting septal deviations. Wall shear stresses are lower in the cases of normal noses in comparison with those for septal deviation. Besides, velocity field distributions, pressure drop between nasopharynx and the ambient, and flow rates in each nostril were different among the nasal cavities in the two groups. These software modules open up a promising future to simulate the nasal airflow behaviour in virtual surgery intervention scenarios under different pressure or

The Usefulness of the Endonasal Incisional Approach for the Treatment of Nasal Bone Fracture

Full Text Available BackgroundAmong all facial fractures, nasal bone fractures are the most common, and they have been reduced by closed reduction (CR for a long time. But several authors have reported suboptimal results when using CR, and the best method of nasal bone reduction is still being debated. We have found that indirect open reduction (IOR through an endonasal incisional approach is a useful method for more accurate reduction of the nasal bone.MethodsA retrospective chart review was performed of 356 patients who underwent reduction of a nasal bone fracture in our department from January, 2006, to July, 2011. We treated 263 patients with IOR. We assessed patients' and doctors' satisfaction with surgical outcomes after IOR or CR. We evaluated the frequency of nasal bleeding owing to mucosal injury, and followed the surgical outcomes of patients who had simultaneous dorsal augmentation rhinoplasty.ResultsAccording to the analysis of the satisfaction scores, both patients and doctors were significantly more satisfied in the IOR group than the CR group (P<0.05. Mucosal injury with nasal bleeding occurred much less in the IOR group (5.3% than the CR group (12.9%. Dorsal augmentation rhinoplasty with IOR was performed simultaneously in 34 cases. Most of them (31/34 showed satisfaction with the outcomes.ConclusionsIOR enables surgeons to manipulate the bony fragment directly through the endonasal incisional approach. However, we propose that CR is the proper technique for patients under 16 and for those with comminuted nasal bone fractures because submucosal dissection in IOR can damage the growth or circulation of nasal bone.

1997-01-01

Preoperative bone CT scans sliced parallel to the surgical plane were evaluated in 32 cases of transsphenoidal surgery. This method predicted patients with narrow nasal cavity, and helped to determine the rhinological maneuvers for providing a wider operative field. In addition, it helps to plan the need and extent of sella floor removal in re-operated cases. There was relatively little difference in the width and length of the nasal cavity between acromegalic and non-acromegalic patients. Hence, bone CT scans are useful in the preoperative evaluation of patients undergoing transsphenoidal surgery. (author)

2015-01-01

The objective of the present study was to estimate the influence of gastroesophageal reflux disease (GERD) on the pH values in the pharynx and nose. It included 87 patients at the age varying from 18 to 81 years admitted to the Irkutsk-based Railway Clinical Hospital and allocated to four groups. Group 1 was comprised of 25 patients presenting with gastroesophageal reflux disease and chronic rhinosinusitis (CRS), group 2 consisted of 29 patients with CRS in the absence of GERD, group 3 included 22 patients with nasal septum deformations (NSD) and GERD, group 4 included 11 patients with NSD and motor rhinitis without GERD. The control group was formed from 10 volunteers. pH was measured by the contact method with the use ofEkokhim indicator paper. Gastroesophageal reflux disease was diagnosed following the recommendations of the Montreal consensus. It was shown that pH values in the pharynx of the patients with compromised nasal breathing of any origin in combination with GERD were lower than in the absence of GERD and in the healthy volunteers. The study groups did not differ in terms of pH values in the nasal cavity. It is concluded that pH values 4 or lower may serve as the criterion for pharyngo-laryngeal reflux (PLR) concomitant with HERD while pH 5 occurs more frequently in the patients with compromised nasal breathing of any etiology, regardless of the presence or absence of GERD.Disordered nasal breathing of any genesis in the patients presenting with gastroesophageal reflux disease was associated with the feeling of the lump in the throat, congestion of the respiratory tract and the nose, pain in the ears, cardialgia, and irregular heartbeat. It isrecommended to use pH measurements as a criterion for diagnostics of pharyngo-laryngeal reflux in the patients presenting with gastroesophageal reflux disease.

2009-10-01

Full Text Available The treatment of patients with unilateral cleft lip has undergone significant development during the last decades. With better understanding of the anatomy of the unilateral cleft lip and nasal deformities, primary correction of the nasal deformity at the time of lip repair, critical evaluation of short and long-term results following various treatment protocols, and constant striving for perfection in both aesthetics and function, we have been able to design improved treatment strategies and more accurate surgical techniques so as to achieve overall superior and long-lasting results. In this review article, we present our protocols and experience for functional and aesthetic correction of secondary unilateral cleft lip nasal deformities and a retrospective review of 219 consecutive patients treated at our Craniofacial Centre for correction of secondary unilateral cleft lip nasal deformities. The protocols used in the treatment of 219 consecutive patients at our Craniofacial Centre for correction of secondary unilateral cleft lip nasal deformities were reviewed. In addition, analysis of the most recent 51 consecutive patients who underwent complete clinical and functional evaluation with rhinomanometry followed by correction of the cleft lip nasal deformity was performed. A variety of time-honoured techniques of rhinoplasty were applied in the correction of the residual deformities to achieve symmetry, aesthetic balance, and functional correction of the nose. Follow-up ranged from 5-11 years. Analysis of the data revealed that 39 patients (76.47% had significant functional and aesthetic improvement; seven patients (13.07% had significant aesthetic improvement but a modest functional improvement; and five patients (9.8% required additional surgery to improve their appearance and had no functional improvement. Further analysis demonstrated that five out of seven patients in the second group had pharyngeal flaps in place that were primarily

Full Text Available Abstract Background Staphylococcus aureus, particularly methicillin resistant (MRSA, is a common pathogen among patients receiving hemodialysis. To evaluate nasal carriage, molecular characterization and effectiveness of decolonization of MRSA among patients receiving hemodialysis in Taiwan, we conducted this study. Methods From January to June 2011, two nasal samplings with a 3-month interval were obtained from patients undergoing hemodialysis in a medical center (CGMH, and in a local hospital (YMH and sent for detection of MRSA. For MRSA carriers, decolonization procedures were administered. All patients in CGMH were observed if MRSA infections occurred during the study period. Results A total of 529 nasal specimens (265 from CGMH and 264 from YMH were collected from 296 patients (161 from CGMH and 135 from YMH. 233 patients participated in both surveys. Average one-time point MRSA carriage rate was 3.8%, and the rate was up to 6.9% for those with two-time point surveys. No additional significant factor for MRSA carriage was identified. Seventy percent of the 20 colonizing MRSA isolates, though categorized as healthcare-associated strains epidemiologically, shared common molecular characteristics of the local community-associated strains. Only one of the 20 MRSA-colonized patients failed decolonization and had persistent colonization, while without any intervention, 17 (61% of 28 patients with methicillin-sensitive S. aureus colonization in the first survey had persistent colonization of a genetically indistinguishable strain. Within the study period, two patients (1.24% in CGMH, one with MRSA colonization (9.1%, developed MRSA infection. Conclusion A substantial proportion of patients receiving hemodialysis in Taiwan had MRSA colonization, mostly genetically community strains. Decolonization procedures may effectively eliminate MRSA colonization and might reduce subsequent MRSA infection in these patients.

Full Text Available Wide field fundus imaging is needed to diagnose, treat, and follow-up patients with retinal pathology. This is more applicable for pediatric patients as repeated evaluation is a challenge. The presently available imaging machines though provide high definition images, but carry the obvious disadvantages of either being costly or bulky or sometimes both, which limits its usage only to large centers. We hereby report a technique of fundus imaging using a nasal endoscope coupled with viscoelastic. A regular nasal endoscope with viscoelastic coupling was placed on the cornea to image the fundus of infants under general anesthesia. Wide angle fundus images of various fundus pathologies in infants could be obtained easily with readily available instruments and without the much financial investment for the institutes.

The aim of this study is to evaluate the role of computed tomography and magnetic resonance imaging in the characterization of deep tissue extension of malignant tumors of the nasal cavity. Twelve patients diagnosed with malignant tumors of the nasal cavity were retrospectively evaluated at the Departments of Diagnostic Imaging and Head and Neck Surgery of the 'Complexo Hospitalar Heliopolis', Sao Paulo, Brazil, between 1990 and 2000. All cases were confirmed by histopathologic examination. The results were: extension to the maxillary and ethmoid sinuses was identified in six patients, extension to contralateral nasal cavity, orbit and lamina cribosa in five patients, extension to nasal pharynx and masticator space in two patients, extension to cavernous sinus, anterior/middle cranial fossa, pterygomaxillary fossa, inferior/superior orbital fissure, frontal sinus, contralateral ethmoid sinus, contralateral lamina cribosa, hard palate and pterygopalatine fossa in one patient. Conclusion: It is important to precisely assess the local extension and spread of tumor by computed tomography and magnetic resonance imaging in order to plan the approach to treatment, which will influence the prognosis.

Full Text Available We report a rare case of nasal glial heterotopia in an adult. After the surgery, frontal lobe cerebral hemorrhage developed. A 58-year-old man had unilateral nasal obstruction that progressed for one year. He had been treated for hypertension, chronic heart failure, and cerebral infarction with aspirin and warfarin. A computed tomography scan showed that the tumor occupied the right nasal cavity and the sinuses with small defect in the cribriform plate. The tumor was removed totally with endoscopy. After the operation, the patient developed convulsions and frontal lobe cerebral hemorrhage. The hemorrhage site was located near a defect in the cribriform plate. Nasal glial heterotopia is a rare developmental abnormality, particularly rare in adult. Only few cases were reported. We could not find any report of adult nasal glial heterotopias that developed cerebral hemorrhage as a complication of the surgery.

Full Text Available Background: Epistaxis is a common problem in childhood. It has been shown that children with recurrent epistaxis are more likely to have nasal colonization with Staphylococcus aureus. It has been suggested that low-grade inflammation, crusting and increased vascularity due to bacterial colonization contributes to the development of epistaxis in children. Aims: This study aimed to investigate the nasal colonization and treatment outcome in pediatric epistaxis patients. Study Design: Retrospective cross-sectional study. Methods: Charts of the pediatric patients referred to our university hospital otolaryngology outpatient clinics for the evaluation of epistaxis were reviewed. The patients whose nasal cultures had been taken at the first clinical visit comprised the study group. Results: Staphylococcus aureus was the most common bacteria grown. The presence of crusting and hypervascularity was not dependent on the type of bacterial growth and there was no relation between hypervascularity and crusting of the nasal mucosa. Thirty-six patients were evaluated for the outcome analysis. Resolution of bleeding was not dependent on nasal colonization; in patients with colonization, there was no difference between topical antibacterial and non-antibacterial treatments. Conclusion: Despite the high colonization rates, topical antibacterial treatment was not found superior to non-antibacterial treatment. Our study does not support the belief that bacterial colonization results in hypervascularity of the septal mucosa causing epistaxis since no relation was found between nasal colonization, hypervascularity and crusting. The role of bacterial colonization in pediatric epistaxis need to be further investigated and treatment protocols must be determined accordingly.

Dynamic hyperinflation is an important target in the treatment of COPD. There is increasing evidence that positive expiratory pressure (PEP) could reduce dynamic hyperinflation during exercise. PEP application through a nasal mask and a flow resistance device might have the potential to be used during daily physical activities as an auxiliary strategy of ventilatory assistance. The aim of this study was to determine the effects of nasal PEP on lung volumes during physical exercise in patients with COPD. Twenty subjects (mean ± SD age 69.4 ± 6.4 years) with stable mild-to-severe COPD were randomized to undergo physical exercise with nasal PEP breathing, followed by physical exercise with habitual breathing, or vice versa. Physical exercise was induced by a standard 6-min walk test (6 MWT) protocol. PEP was applied by means of a silicone nasal mask loaded with a fixed-orifice flow resistor. Body plethysmography was performed immediately pre-exercise and post-exercise. Differences in mean pre- to post-exercise changes in total lung capacity (-0.63 ± 0.80 L, P = .002), functional residual capacity (-0.48 ± 0.86 L, P = .021), residual volume (-0.56 ± 0.75 L, P = .004), S(pO2) (-1.7 ± 3.4%, P = .041), and 6 MWT distance (-30.8 ± 30.0 m, P = .001) were statistically significant between the experimental and the control interventions. The use of flow-dependent expiratory pressure, applied with a nasal mask and a PEP device, might promote significant reduction of dynamic hyperinflation during walking exercise. Further studies are warranted addressing improvements in endurance performance under regular application of nasal PEP during physical activities.

Despite the increasing application of endoscopic transsphenoidal surgery for pituitary lesions, the prognostic factors that are associated with sinonasal quality of life (QOL) and nasal morbidity are not well understood. The authors examine the predictors of sinonasal QOL and nasal morbidity in patients undergoing fully endoscopic transsphenoidal surgery. An exploratory post hoc analysis was conducted of patients who underwent endoscopic pituitary surgery and were enrolled in a prospective multicenter QOL study. End points of the study included patient-reported sinonasal QOL and objective nasal endoscopy findings. Multivariate models were developed to determine the patient and surgical factors that correlated with QOL at 2 weeks through 6 months after surgery. This study is a retrospective review of a subgroup of patients studied in the clinical trial "Rhinological Outcomes in Endonasal Pituitary Surgery" (clinical trial no. NCT01504399, clinicaltrials.gov ). Data from 100 patients who underwent fully endoscopic transsphenoidal surgery were included. Predictors of a lower postoperative sinonasal QOL at 2 weeks were use of nasal splints (p = 0.039) and female sex at the trend level (p = 0.061); at 3 months, predictors of lower QOL were the presence of sinusitis (p = 0.025), advancing age (p = 0.044), and use of absorbable nasal packing (p = 0.014). Health status (multidimensional QOL) was also predictive at 2 weeks (p = 0.001) and 3 months (p surgery. The mean time (± SEM) to absence of nasal crusting was 16.3 ± 2.1 weeks, mucopurulence was 6.2 ± 1.1 weeks, and synechia was 4.4 ± 0.5 weeks. Use of absorbable nasal packing was associated with more severe mucopurulence. Sinonasal QOL following endoscopic pituitary surgery reaches a nadir at 2 weeks and recovers by 3 months postoperatively. Use of absorbable packing and nasal splints, while used in a minority of patients, negatively correlates with early sinonasal QOL. Sinonasal QOL and overall health status are

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.

In teenagers with perennial allergic rhinitis, exposure to tobacco cigarette smoke increases the count of eosinophils in the nasal mucosa; the recruitment of eosinophils arises from the combined action of a number of cellular and molecular signals, including eotaxin. To assess the effect of exposure to tobacco cigarette smoke on the count of immunoreactive cells to eotaxin-1 and eosinophils on the nasal mucosa of children and teenagers with perennial allergic rhinitis. In a cross-sectional study, forty-four patients were evaluated (aged 7-19 years old): 22 with and 22 with no exposure to tobacco cigarette smoke. After replying to 2 validated questionnaires, on Asthma and Allergies in Childhood and on the severity of nasal symptoms, nasal mucosal samples were obtained by scraping the middle one-third of the inferior turbinates. Then counts of immunoreactive cells to eotaxin-1 and eosinophils were assessed by immunohistochemistry. Patients with exposure to tobacco cigarette smoke showed higher cell counts of both eotaxin-1 and eosinophils than patients with no exposure to the smoke, with no correlation between the two variables. However, both counts, of eotaxin-1 and eosinophils, were related to the cotinine/creatinine ratio. Exposure to tobacco cigarette smoke can increase eotaxin-1 and the count of eosinophils in the nasal mucosa of young patients with perennial allergic rhinitis.

Benzalkonium chloride is a preservative commonly used in nasal decongestant sprays. It has been suggested that benzalkonium chloride may be harmful to the nasal mucosa. Decongestion with the vasoconstrictor xylometazoline containing benzalkonium chloride has been shown to cause a significant reduction of the nasal mucosal temperature. The purpose of the present study was to determine the short-term influence of xylometazoline nasal spray with and without benzalkonium chloride on the nasal mucosal temperature. Healthy volunteers (30) were included in the study. Fifteen volunteers received xylometazoline nasal spray (1.0 mg/mL) containing benzalkonium chloride (0.1 mg/mL) and 15 age-matched subjects, received xylometazoline nasal spray without benzalkonium chloride. Using a miniaturized thermocouple the septal mucosal temperature was continuously measured at defined intranasal detection sites before and after application of the nasal spray. The mucosal temperature values did not significantly differ between the group receiving xylometazoline containing benzalkonium chloride and the group receiving xylometazoline spray without benzalkonium chloride before and after decongestion (P > 0.05). In both study groups septal mucosal temperatures significantly decreased after decongestion (P reduction of the nasal mucosal blood flow following vasoconstriction. This study indicates that benzalkonium chloride itself does not seem to influence nasal blood flow and nasal mucosal temperature in topical nasal decongestants.

The treatment of choice for patients with respiratory failure of neuromuscular origin, especially in patients with hypercapnic respiratory acidosis, is noninvasive ventilation (NIV). Endotracheal intubation and invasive ventilation are indicated for patients with severe respiratory compromise or failure of NIV. In recent years, high-flow oxygen therapy and active humidification devices have been introduced, and emerging evidence suggests that high-flow oxygen may be effective in various clinical settings, such as acute respiratory failure, after cardiac surgery, during sedation and analgesia, in acute heart failure, in hypoxemic respiratory distress, in do-not-intubate patients, in patients with chronic cough and copious secretions, pulmonary fibrosis, or cancer, in critical areas and the emergency department. We report on a patient with amyotrophic lateral sclerosis who arrived at the emergency department with acute hypercapnic respiratory failure. She did not tolerate NIV and refused intubation, but was treated successfully with heated, humidified oxygen via high-flow nasal cannula. Arterial blood analysis after an hour on high-flow nasal cannula showed improved pH, P(aCO2), and awareness. The respiratory acidosis was corrected, and she was discharged after 5 days of hospitalization. Her response to high-flow nasal cannula was similar to that expected with NIV. We discuss the mechanisms of action of heated, humidified high-flow oxygen therapy.

Extranodal NK/T-Cell lymphoma, nasal type (NKTLN) is a disease that mainly affects the nasal cavity and the paranasal sinuses. Early nasal symptoms are nonspecific, simulating sinus infection. With disease progression, necrosis of the nasal mucosa increases, hindering histological diagnosis. Thus, multiple biopsies may be necessary until definitive diagnosis. Most studies on NKTLN address the hematological and immunological aspects of the disease. To present data from a Brazilian quaternary hospital, with emphasis on the clinical aspects of the disease, and to correlate the findings with the most recent literature data. Case study of seven patient files. Patients were evaluated on their medical history, number of biopsies necessary, association with Epstein-Barr virus, treatment, and outcome. All patients had nonspecific nasal complaints and underwent at least three cycles of antibiotic therapy. The earlier a biopsy was performed, the fewer biopsies were required to diagnose the disease and start treatment. However, this fact did not translate into better prognosis. The otolaryngologist plays a fundamental role in the prognosis of NKTLN and can shorten time between symptom onset and treatment of the patient.

Full Text Available Nasal lobular capillary hemangioma is a rare benign tumor of the paranasal sinuses. This lesion is believed to grow rapidly in size over time. The exact etiopathogenesis is still a dilemma. We discuss a case of nasal lobular capillary hemangioma presenting with a history of epistaxis. Contrast enhanced computed tomography of paranasal sinuses revealed an intensely enhancing soft-tissue mass in the left nasal cavity and left middle and inferior meati with no obvious bony remodeling or destruction. We present imaging and pathologic features of nasal lobular capillary hemangioma and differentiate it from other entities like nasal angiofibroma.

Hereditary hemorrhagic telangiectasia (HHT) is a dominantly inherited genetic vascular disorder in which epistaxis is the most frequent manifestation, responsible for high morbidity. Management of this symptom has no standard, and local treatments are often aggressive. Their efficacy is variable and has not been proven. Anti-angiogenic drugs, such as bevacizumab, are a new treatment strategy. Its systemic administration in patients with HHT improves liver damage-related symptoms and epistaxis. To limit the systemic adverse effects of bevacizumab and to ease administration, a local administration seems suitable. To evaluate the tolerance of increasing doses of bevacizumab administered as a nasal spray in patients with HHT-related epistaxis. Secondary objectives were to study the bioavailability and efficacy of bevacizumab against epistaxis when given as a nasal spray. Phase 1, randomized, double-blind, placebo-controlled, monocentric study performed sequentially (dose escalation) on 5 groups of 8 patients. Each group was made up of 6 verum and 2 placebos. Five increasing doses of bevacizumab nasal spray (25 mg/mL) were evaluated: 12.5, 25, 50, 75 and 100 mg. A total of 40 patients were included between October 2011 and October 2012. Bevacizumab nasal spray was well tolerated in all patients and the drug was not detected in their serum. No dose limiting toxicity was observed. No efficacy was observed at any dose in this study. Based on these results, bevacizumab nasal spray is a safe treatment of epistaxis in HHT. However, a randomized Phase 2 study is needed to determine its efficacy.

Esthesioneuroblastoma is an uncommon cancer of the nasal cavity. We describe the outcomes for 26 patients treated with curative intent with photon radiotherapy (RT) at the University of Florida. Between May 1972 and June 2007, 26 patients received RT for previously untreated esthesioneuroblastoma of the nasal cavity. Sixteen patients were males and 10 were females with a median age of 55 years (range, 3 to 82 y). The modified Kadish stage distribution was: B, 7 patients; C, 17 patients; and D, 2 patients. Treatment modalities included the following: definitive RT, 5 patients; preoperative RT, 2 patients; and postoperative RT after resection, 19 patients. Elective neck irradiation (ENI) was performed in 17 (71%) of 24 N0 patients. Rates of local control, cause-specific survival, and absolute overall survival at 5 years were 79%, 72%, and 69%, respectively. Overall survival among patients treated with definitive RT was 20% at 5 years, compared with 81% among those who underwent surgery and adjuvant RT (P=0.01). One (6%) of 17 patients who received ENI developed a recurrence in the neck and was successfully salvaged. Ultimate neck control was 100% at 5 years for patients who received ENI versus 69% among those not receiving ENI (P=0.0173). Resection combined with adjuvant RT is more effective than surgery or RT alone in the treatment of esthesioneuroblastoma. ENI reduces the risk of regional relapse in patients with Kadish stage B and C cancers.

Full Text Available Monitoring the results of surgery is important. The otorhinolaryngology department of our hospital currently uses preoperative and postoperative versions of the Nasal Surgical Questionnaire (NSQ for continuous evaluation of nasal septoplasty. In this study, 55 patients undergoing septoplasty answered the preoperative version twice to assess the NSQ’s test-retest precision, and 75 patients answered the preoperative questionnaire before and the postoperative one 6 months after surgery to evaluate the NSQ’s ability to detect change in symptoms following surgery. Both the pre- and postoperative versions of the NSQ use separate visual analogue scales (VAS to assess nasal obstruction during the day, at night, and during exercise. Other nasal symptoms are graded as secondary outcomes using 4-point Likert scales. The mean VAS scores for the two preoperative obstruction ratings were not significantly different. The scores were significantly higher than in a normal population. There were also significant differences between preoperative and postoperative ratings. The mean pre- and postoperative scores at night for those who reported complete improvement were 66.1 and 8.4, substantial improvement 74.5 and 24.2, and no improvement 83.3 and 76.4. The NSQ reliably assesses nasal symptoms in patients and may be useful for both short and long term prospective studies of septoplasty.

Full Text Available Since nasal NK/T-cell lymphoma and NK/T-cell lymphoma nasal type are rare diseases, colonic involvement has seldom been seen. We report a case of a patient with a primary NK/T-cell lymphoma nasal type of the colon. The patient had no history of malignant diseases and was diagnosed after exhaustive study in the context of fever of unknown origin. The first therapeutic approach followed the DAEPOCH-protocol: etoposide, prednisone, doxor-rubicin, vincristine and cyclophosphamide. The persistence of constitutional symptoms after the first treatment course motivated the switch to a second line following the SMILE-protocol: dexamethasone, metotrexate, ifosfamide, E.coli L-asparaginase, and etoposide. Despite intensive chemotherapy, the patient died 2 months after the diagnose of an extranodal NK/T-cell lymphoma of the colon and 4 months after the first symptomatic appearance of disease.

This study was to evaluate the survival and pattern of failure after radiation therapy of sino-nasal cancer using partial attenuation filer and wedged beams and to help radiotherapy planning of sino-nasal cancer. Between February 1992 and March 2003, 17 patients with sino-nasal cancers underwent radiation therapy using partial attenuation filter at Dongsan Medical Center, Keimyung university. There were 9 male and 8 female patients. Patients' age ranged from 40 to 75 years (median 59 years). There were 10 patients of maxillary sinus cancer, 7 patients of nasal cancer. The histologic type was squamous cell carcinoma in 11, adenoid cystic carcinoma in 4 and olfactory neuroblastoma in 2. The distribution of clinical stage by the AJCC system was 3 for stage II, 7 for III and 6 for IV. The five patients were treated with radiation alone and 12 patients were treated with surgery and postoperative radiation therapy. The range of total radiation dose delivered to the primary tumor was from 44 to 76 Gy (median 60 Gy). The follow-up period ranged from 3 to 173 months with median of 78 months. The overall 2 year survival rate and disease free survival rate was 76.4%. The 5 year and 10 year survival rate were 76.4% and 45.6% and the 5 year and 10 year disease free survival rate was 70.6%. The 5 year disease free survival rate by treatment modality was 91.6% for postoperative radiation group and 20% for radiation alone group, statistical significance was found by treatment modality ({rho} = 0.006). There were no differences in survival by pathology and stage. There were local failure in 5 patients (29%) but no distant failure and no severe complication required surgical intervention. Radiation therapy of sino-nasal cancer using partial attenuation filter was safe and effective. Combined modality with conservative surgery and radiation therapy was more advisable to achieve loco-regional control in sino-nasal cancer. Also we considered high precision radiation therapy with

A study has been carried out to assess the mucociliary function of nasal mucosa in 30 patients: 16 had undergone surgery due to larynx malignancy and the remaining 14 were divided in two groups. The first group was composed of seven patients suffering from larynx cancer but not operated, and the second group of seven had pathology not related to the airways (control group). The method used a sup(99m)technetium sulphur colloid drop deposited on the nasal mucosa of one nostril. To calculate the rate of transport, a new method of quantification has been introduced, based on the formation of a parametric image. The mean velocity in laryngectomees was 3.6 mm/min (range 1.1-6.4). It was compared with the group of 14 patients without tracheostomy (mean 5.3, range 3.3-8.2). An impaired student's-t-test gave a significant difference between both groups (P<0.005). The comparison between patients with nonoperated larynx cancer and normals have a nonsignificant difference. The 16 operated patients were arbitrarily divided into two groups as per the time elapsed from laryngectomy; seven were studied within the first 3 years of operation and seven other patients after this term. The comparison between them was not significant. (orig.)

Full Text Available Objectives: To define the role of endoscopic evaluation of middle meatus in adult patients clinically diagnosed to have chronic rhino-sinusitis and its ability to predict intra-sinus mucosal involvement as compared to CT scan.Methods: This prospective analytical study was conducted on consecutive patients with diagnosis of chronic rhino-sinusitis who were symptomatic and fulfilled the American Academy of Otolaryngology - Head and Neck Surgery Task Force criteria. The patients were enrolled prospectively and were subjected to rigid diagnostic nasal endoscopy and classified as defined by the revised Sinus Allergy Health Partnership Task Force criteria. The patients then underwent non contrast CT sinuses on the same day. Results were analyzed as a diagnostic test evaluation using CT as a gold standard.Results: Among the 75 study patients with symptom based chronic rhino-sinusitis, nasal endoscopy was abnormal in 65 patients (87%. Of these patients, 60/65 (92% showed positive findings on CT scan. Ten patients had normal endoscopy, of these 6/10 (60% had abnormal CT scan. Sensitivity and specificity of diagnostic nasal endoscopy against CT scan were 91% (95% CI: 81-97 and 44% (95% CI: 14-79, respectively. The likelihood ratio for positive nasal endoscopy to diagnose chronic rhino-sinusitis was 1.6 and the likelihood ratio to rule out chronic rhino-sinusitis when endoscopy was negative was 0.2.Conclusion: Nasal endoscopy is a valid and objective diagnostic tool in the work up of patients with symptomatic chronic rhino-sinusitis. When clinical suspicion is low (90% of patients when clinical suspicion is high (88% as defined in this study by AAO-HNS Task Force criteria. Negative endoscopy, however, does not totally exclude the sinus disease in patients fulfilling task force criteria. CT scan may be needed on follow-up if there is clinical suspicion in 10% of these patients who are negative on endoscopy if symptoms persists. It is thus possible to reduce

Full Text Available Introduction: Solitary fibrous tumours (SFTs of the nose and paranasal sinuses are extremely rare.These were originally described as neoplasms of the pleura originating from spindle cells. It is further sub-classified as a benign type of mesothelial tumour. Its occurrence in many extra pleural sites have been reported earlier, mainly in the liver, parapharyngeal space, sublingual glands, tongue, parotid gland, thyroid, periorbital region, and very occasionally in the nose and  paranasal sinus area.   Case Report: A 28-year-old man with a 6 month history of persistent progressive left nasal obstruction and watering of the left eye is reported. Further imaging by CT and MRI revealed a large, left-sided, highly vascular, nasal cavity mass (Fig 1,2,3,4 pushing laterally on the medial wall of the maxilla. The patient underwent a lateral rhinotomy, which proceeded with the excision of the mass. Histopathological analysis of the specimen was consistent with SFT.   Conclusion:  This case is reported to develop insights regarding diagnosis and management of such rare tumours.

Patients with allergic rhinitis demonstrate hyperreactive response in distilled water nasal provocation, shown by significant increase in nasal airway resistance (NAR). Antihistamines, including topical antihistamine, levocabastine, reduce response in non-specific nasal provocation tests. Furosemide is a diuretic which reduces hyperreactivity in lower airways, but the mode of its action is not yet fully understood. In this study, we hypothesized that either levocabastine or furosemide pre-treatment in allergic rhinitis patients reduced response to nasal challenge with non-isotonic aerosol. To test the hypothesis, we measured the effect of pre-treatment with levocabastine and furosemide in topical application on suppression of hyperreactive response to distilled water nasal inhalation. Nasal resistance was measured, prior to and after the provocation, by active anterior rhinomanometry in two randomized groups of patients, according to pre-treatment, either by levocabastine or furosemide, 20 patients in each group, respectively. Nasal airflow resistance and level of hyperreactive response considering nasal eosinophilia were tested. Significant increase in nasal resistance following provocation was found at baseline conditions (without pre-medication); pre-treatment with levocabastine and furosemide has suppressed such response. Patients with positive nasal eosinophilia showed a significantly higher increase in nasal resistance compared to those with negative smears. Furosemide has shown significantly better protective effect on nasal resistance increase in patients with positive eosinophils nasal smears. Levocabastine and furosemide pre-treatment suppress hyperreactive response to distilled water nasal provocation. Comparison of resistances (pre-treatment vs. without) showed more protective effect of furosemide, measured on both better and worse patent side of nose, in contrast to levocabastine group for which it was shown only on better patent side prior to

Full Text Available Nasal aspergillosis is a major chronic disease affecting the nostrils in dogs. Clinical sinology is typical in every chronic nasal disease. Epistaxis and occasional pain occurs. Rhinoscopic assessment of the area evidences findings associated with the pathology and allows collecting samples for cytology and culture. Systemic therapy with oral antifungals has had variable utility, but now it has been replaced by direct topical medication to the affected area. This article describes the case of a 4-years-old male dog, submitted to consultation by unilateral muco-bloody nasal discharge with a week of evolution. The patient was treated by another vet center with cyclonamine and vitamin K for a possible clotting disorder. After a series of tests that included rhinoscopy and fungal culture, nasal aspergillosis was diagnosed. Intranasal clotrimazole was applied twice and it allowed the resolution of the clinical signs.

Optimal oxygen supply is the cornerstone of the management of critically ill patients after extubation, especially in patients at high risk for extubation failure. In recent years, high flow oxygen system devices have offered an appropriate alternative to standard oxygen therapy devices such as conventional face masks and nasal prongs. To assess the clinical effects of high flow nasal cannula (HFNC) compared with standard oxygen face masks in Intensive Care Unit (ICU) patients after extubation. We retrospectively analyzed 67 consecutive ventilated critical care patients in the ICU over a period of 1 year. The patients were allocated to two treatment groups: HFNC (34 patients, group 1) and non-rebreathing oxygen face mask (NRB) (33 patients, group 2). Vital respiratory and hemodynamic parameters were assessed prior to extubation and 6 hours after extubation. The primary clinical outcomes measured were improvement in oxygenation, ventilation-free days, re-intubation, ICU length of stay, and mortality. The two groups demonstrated similar hemodynamic patterns before and after extubation. The respiratory rate was slightly elevated in both groups after extubation with no differences observed between groups. There were no statistically significant clinical differences in PaCO2. However, the use of HFNC resulted in improved PaO2/FiO2 post-extubation (P < 0.05). There were more ventilator-free days in the HFNC group (P< 0.05) and fewer patients required reintubation (1 vs. 6). There were no differences in ICU length of stay or mortality. This study demonstrated better oxygenation for patients treated with HFNC compared with NRB after extubation. HFNC may be more effective than standard oxygen supply devices for oxygenation in the post-extubation period.

Resection of cancer often involves the excision of underlying hard tissue, and some procedures in aesthetic rhinoplasty can be used in reconstructive nasal surgery to increase the margin of safety while still achieving an acceptable aesthetic and functional outcome. We have used techniques from aesthetic rhinoplasty to shape the nasal framework. Osteotomy and formation of the tip were used in 17 patients with defects (ranging from 1 to 3.5 cm in size) from the nasal root to the tip of the nose. After the underlying bony or cartilaginous framework, or both, had been removed, the resulting open roof deformity had to be corrected by osteotomy of the bony nasal wall and the tip shaped by excision and suturing, including insertion of the tip graft and columellar strut graft. After this, and narrowing of the nose, the defect was smaller and could be closed with local tissue without tension. There were no deformities in the contour, and patency of the airway was maintained. Patients were satisfied with both the aesthetic and functional results. Although the margin of safety was increased, shaping the nasal framework reduced the size of the defect, which allowed tension-free closure with a local flap. The operation requires a thorough knowledge of procedures used in aesthetic rhinoplasty. Copyright © 2014 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

Rare occupational cause of nasal septum perforation: Nickel exposure

Directory of Open Access Journals (Sweden)

2017-10-01

Full Text Available Many etiologies are held accountable for nasal septum perforations. Topical nasal drug usage, previous surgeries, trauma, nose picking, squamous cell carcinoma, some rheumatological disorders such as granulomatosis with polyangiitis (Wegener granulomatosis, some infectious diseases such as syphilis and leprosy are among the causes of the perforations. Occupational heavy metal exposures by inhalation rarely may also cause nasal septum perforation. Here, we present a 29-year-old patient without any known diseases, who is a worker at a metallic coating and nickel-plating factory, referred for investigation of his nasal cartilage septum perforation from an otorhinolaryngology clinic. The patient questioning, physical examination and laboratory assessment about rheumatic and infectious diseases were negative. There was a metallic smell in the breath during the physical examination. The analysis showed serum nickel level at 31 μg/l and urine nickel at 18 μg/l (84.11 μg/g creatinine. Other possible serum and urine heavy metal levels were within normal ranges. Nickel exposure is usually together with other heavy metals (chromium or cadmium, it is rarely alone. Nickel ingested by inhalation usually leads to respiratory problems such as reduced olfactory acuity, ulcers, septum perforation or tumors of the nasal sinuses. This case demonstrates the importance of occupational anamnesis and awareness of diagnosis. Int J Occup Med Environ Health 2017;30(6:963–967

Staphylococcus aureus is the main cause of diabetic foot infection with the patient's endogenous flora as the principal source. Nasal carriage of S. aureus has been identified as an important risk factor for the acquisition of diabetic foot infections. The study assessment the associations of S. aureus with methicillin resistant S. aureus were isolation from diabetic foot infection and nasal carriage of the same patients and their antibiotic susceptibility profile. Diagnosis of S. aureus and methicillin resistant S. aureus were carried out by using standard procedures. Antibiotic sensitivity profiles were determent by breakpoint dilution method. Out of 222 S. aureus isolation, 139 (62.61%) were isolated from the diabetic foot and 83 (37.39%) from the nasal carriage. Seventy one (30.87%) of the patients were S. aureus infection diabetic foot with nasal carriage. Among diabetic foot infection and nasal carriage patients, 40.85% of S. aureus were considered as methicillin resistant S. aureus. Rifampicin (96.40%) and Levofloxacin (91.44%) were active against S. aureus. Patients at strong risk for methicillin resistant S. aureus nasal carriage and subsequent diabetic foot infection with high resistance to antibiotics. Copyright © 2012 Elsevier Ltd.

The Ejnell method used to treat bilateral vocal cord paralysis without damaging the laryngeal framework. It is the first-line option for laterofixation of the vocal fold, because it is reversible and requires no tracheotomy. The Ejnell method normally requires direct laryngoscopy. It was applied without direct laryngoscopy in one patient, because a patient had difficulty extending the neck after radiation therapy. Nasal ENDO CLOSE TM was effective under flexible fiberscopy. Therefore, this could be an effective method a patient cannot undergo direct laryngoscopy. (author)

Nasal obstruction is known to cause resistance to continuous positive airway pressure (CPAP) therapy in obstructive sleep apnea syndrome (OSAS). In this paper, short- and long-term nasal congestion in OSAS patients receiving CPAP treatment were evaluated with acoustic rhinometry (AR). A total of 36 patients with moderate-to-severe OSAS, diagnosed with polysomnography were included in the study. Ten healthy subjects without OSAS constituted the control group. Pre-treatment nasal patency were measured with AR in all participants. 26 patients used the recommended CPAP treatment. Ten patients did not accept CPAP treatment. The AR test was repeated for all the subjects after 1 and 3 months except the 3rd month's measurements of the control group. There was no statistically significant difference between the initial minimum cross-sectional area (MCA) measurements of OSAS patients, using or not using CPAP, and the control group (P > 0.05). However, the first month MCA measurements of patients receiving CPAP were found to be significantly decreased compared with the initial values (P CPAP (P > 0.05). No significant difference revealed in the 3rd month MCA measurements of the patients using CPAP compared with the initial values (P > 0.05). In this study, the increased nasal congestion, which is thought to be the cause of CPAP resistance, was objectively demonstrated in OSAS patients using CPAP. In addition, the nasal congestion developing at the first month was shown to disappear over time, supporting the opinion that patient compliance in CPAP treatment is expected to increase after regular device usage.

Juvenile angiofibroma is an uncommon, benign, locally aggressive vascular tumor. It is found almost exclusively in young men. Common presenting symptoms include nasal obstruction and epistaxis. More advanced tumors may present with facial swelling and visual or neurological disturbances. The evaluation of patients with juvenile angiofibroma relies on diagnostic imaging. Preoperative biopsy is not recommended. The mainstay of treatment is resection combined with preoperative embolization. Endoscopic surgery is the approach of choice in early stages, whereas, in advanced stages, open or endoscopic approaches are feasible in expert hands. Postoperative radiotherapy (RT) or stereotactic radiosurgery seem valuable in long-term control of juvenile angiofibroma, particularly those that extend to anatomically critical areas unsuitable for complete resection. Chemotherapy and hormone therapy are ineffective. The purpose of the present review was to update current aspects of knowledge related to this rare and challenging disease. © 2017 Wiley Periodicals, Inc.

Recent studies have examined the effects of intranasal corticosteroids (INSs) in relieving the ocular symptoms of seasonal allergic rhinoconjunctivitis (SAR) and perennial allergic rhinitis. However, because most of these studies were based on subjective assessments by patients, the associated factors and mechanism of action are unknown. A single-center, randomized, double-blind, parallel-group study was carried out in which patients with SAR were randomly assigned to an INS mometasone furoate nasal spray (MFNS) group or to a placebo group and treated once daily for 4 weeks. Substance P concentrations in tears were measured, ocular and nasal symptoms were recorded by patients in an allergy diary, and findings were recorded by an ophthalmologist. There was no significant difference between treatment groups in the mean change from baseline of substance P concentration in tears after 4 weeks of treatment, but the mean change tended to increase in the placebo group and tended to decrease in the MFNS group (P = 0.089). All ocular and nasal symptom scores, except eye tearing, were significantly lower in the MFNS group than in the placebo group. Furthermore, substance P concentrations were strongly correlated with ocular and nasal symptom scores. In patients with SAR, INSs tend to decrease the substance P concentration in tears, which is correlated with the severity of ocular and nasal symptoms.

Definite diagnosis of sporadic Creutzfeldt-Jakob disease in living patients remains a challenge. A test that detects the specific marker for Creutzfeldt-Jakob disease, the prion protein (PrP(CJD)), by means of real-time quaking-induced conversion (RT-QuIC) testing of cerebrospinal fluid has a sensitivity of 80 to 90% for the diagnosis of sporadic Creutzfeldt-Jakob disease. We have assessed the accuracy of RT-QuIC analysis of nasal brushings from olfactory epithelium in diagnosing sporadic Creutzfeldt-Jakob disease in living patients. We collected olfactory epithelium brushings and cerebrospinal fluid samples from patients with and patients without sporadic Creutzfeldt-Jakob disease and tested them using RT-QuIC, an ultrasensitive, multiwell plate-based fluorescence assay involving PrP(CJD)-seeded polymerization of recombinant PrP into amyloid fibrils. The RT-QuIC assays seeded with nasal brushings were positive in 30 of 31 patients with Creutzfeldt-Jakob disease (15 of 15 with definite sporadic Creutzfeldt-Jakob disease, 13 of 14 with probable sporadic Creutzfeldt-Jakob disease, and 2 of 2 with inherited Creutzfeldt-Jakob disease) but were negative in 43 of 43 patients without Creutzfeldt-Jakob disease, indicating a sensitivity of 97% (95% confidence interval [CI], 82 to 100) and specificity of 100% (95% CI, 90 to 100) for the detection of Creutzfeldt-Jakob disease. By comparison, testing of cerebrospinal fluid samples from the same group of patients had a sensitivity of 77% (95% CI, 57 to 89) and a specificity of 100% (95% CI, 90 to 100). Nasal brushings elicited stronger and faster RT-QuIC responses than cerebrospinal fluid (PCreutzfeldt-Jakob disease and indicated substantial prion seeding activity lining the nasal vault.

Nasal bleeding where the lesion cannot clearly be localized is today usually treated with different forms of nasal packings which are traumatizing to the nasal mucosa and often causes the patient discomfort. In an attempt to develop a more convenient form of treatment the effect of two vasoconstrictor gels on nasal mucosal blood flow was evaluated. Terlipressin gel was shown to reduce nasal blood flow in a dose-dependent way. Therefore, this gel was chosen in a double-blind comparison with placebo in the treatment of 44 patients with posterior epistaxis. Although 50% of the patients did stop bleeding after topical gel administration into the nose there was no statistically significant difference in effect between those who received terlipressin gel and those who received placebo gel. We cannot disregard the fact, however, that the gel in itself has a beneficial effect on nose-bleeding.

Besides the opioids the standard management of the World Health Organization suggests NSAIDs (non-steroidal anti-inflammatory drugs) alone or in combination to enhance analgesia in malignant and non-malignant pain therapy. The applicability of NSAIDs in a nasal formulation is a new approach in pharmaceutical technology. In order to enhance the nasal absorption of meloxicam (MX) as an NSAID, its salt form, meloxicam potassium monohydrate (MXP), registered by Egis Plc., was investigated in comparison with MX. The physico-chemical properties of the drugs (structural analysis, solubility and dissolution rate) and the mucoadhesivity of nasal formulations were controlled. In vitro and in vivo studies were carried out to determine the nasal applicability of MXP as a drug candidate in pain therapy. It can be concluded that MX and MXP demonstrated the same equilibrium solubility at the pH5.60 of the nasal mucosa (0.017mg/ml); nonetheless, MXP indicated faster dissolution and a higher permeability through the synthetic membrane. The animal studies justified the short T max value (15min) and the high AUC of MXP, which is important in acute pain therapy. It can be assumed that the low mucoadhesivity of MXP spray did not increase the residence time in the nasal cavity, and the elimination from the nasal mucosa was therefore faster than in the case of MX. Further experiments are necessary to prove the therapeutic relevance of this MXP-containing innovative intranasal formulation. Copyright © 2016 Elsevier B.V. All rights reserved.

Adenoid cystic carcinoma of the nasal septum: A rare case report

Directory of Open Access Journals (Sweden)

2013-01-01

Full Text Available A 60-year-old male patient came to ENT OPD with complaints of left nasal obstruction from the last 5 years and moderate quantity of epistaxis from the last 4 months. It was associated with foul smelling mucopurulent rhinorrhea. On clinical examination, a fleshy mass was seen occupying the posterior part of left nasal cavity and displacing the septum on the right side. The mass was relatively painful, soft, and bleeding on touch. The provisional diagnosis of "vascular-tumor-like" angiofibroma was suspected. Diagnostic nasal endoscopy and CT scan PNS were done which revealed a mass occupying the left nasal cavity arising from the posterior part of septum along the choanae till the anterior part of sphenoid sinus. Biopsy of the same revealed an adenoid cystic carcinoma. Adenoid cystic carcinoma is uncommon and that too of the nasal cavity. The cases of the adenoid cystic carcinoma involving the nasal cavity usually involves the lateral wall and the involvement of the posterior part of nasal septum is extremely rare. Thus the presentation of this uncommon disease is discussed here.

Silver nasal sprays: misleading Internet marketing.

Gaslin, Michael T; Rubin, Cory; Pribitkin, Edmund A

2008-04-01

Long-term use of silver-containing products is associated with a permanent bluish-gray discoloration of the skin known as argyria, but they remain widely available despite several measures by the FDA to regulate them. Several recent case reports have described the occurrence of argyria as a result of using these "natural" products. We used the five most common Internet search engines to find Web sites providing information on silver-containing nasal sprays. Of 49 Web sites analyzed, only 2 (4%) mentioned argyria as a possible complication, although 30 (61%) did caution against long-term use. Eight sites (16%) made specific claims about the health benefits of the product. All 49 sites (100%) provided direct or indirect links to buy silver-containing nasal sprays. We conclude that information about silver-containing nasal sprays on the Internet is misleading and inaccurate. Therefore, otolaryngologists should be aware of the misinformation their patients may be receiving about these products.

1999-01-01

Objective: To evaluate display ability of virtual endoscopy and its clinical application in comparison with fiberoptic nasal endoscopy. Methods: 11 patients (22 nasal cavities) were examined by virtual endoscopy after axial spiral CT scanning was performed. Virtual endoscopy was performed by Explorer software package in a computer workstation. 9 patients (18 nasal cavities) underwent fiberoptic endoscopy. Results: Virtual endoscopy could clearly demonstrate the anatomical structures in nasal cavity, septal deviation, nasal meatus narrowing and obstruction, turbinate hyperplasia, and pathological masses larger than 3 mm in diameter. However, 'false adhesions' may appear in virtual endoscopy. The main limitation of virtual endoscopy was inability to evaluate mucosa and lack of histological diagnosis. Conclusions: Virtual endoscopy is a new, non-invasive method for demonstrating anatomical structures and diseases in nasal cavity. Its display ability is comparable with fiberoptic nasal endoscopy and is a supplement to fiberoptic nasal endoscopy

To describe an alar cartilage-modifying technique aimed at decreasing nasal tip projection in cases with overdeveloped alar cartilages and to compare it with other deprojection techniques used to correct such deformity. Selected case series. University and private practice settings in Alexandria, Egypt. Twenty patients presenting for rhinoplasty who had overprojected nasal tips primarily due to overdeveloped alar cartilages. All cases were primary cases except for one patient, who had undergone 2 previous rhinoplasties. An external rhinoplasty approach was used to set back the alar cartilages by shortening their medial and lateral crura. The choice of performing a high or low setback depended on the preexisting lobule-to-columella ratio. Following the setback, the alar cartilages were reconstructed in a fashion that increased the strength and stability of the tip complex. Subjective evaluation included clinical examination, analysis of preoperative and postoperative photographs, and patient satisfaction. Objective evaluation of nasal tip projection, using the Goode ratio and the nasofacial angle, was performed preoperatively and repeated at least 6 months postoperatively. A low setback was performed in 16 cases (80%) and a high setback in 4 (20%). The mean follow-up period was 18 months (range, 6-36 months). The technique effectively deprojected the nasal tip as evidenced by the considerable postoperative decrease in values of the Goode ratio and the nasofacial angle. No complications were encountered and no revision surgical procedures were required. The alar setback technique has many advantages; it results in precise predictable amounts of deprojection, controls the degree of tip rotation, preserves the natural contour of the nasal tip, respects the tip support mechanisms, increases the strength and stability of nasal tip complex, preserves or restores the normal lobule-to-columella proportion, and does not lead to alar flaring. However, the technique requires

Full Text Available Background Among all facial fractures, nasal bone fractures are the most common, andthey have been reduced by closed reduction (CR for a long time. But several authors havereported suboptimal results when using CR, and the best method of nasal bone reduction isstill being debated. We have found that indirect open reduction (IOR through an endonasalincisional approach is a useful method for more accurate reduction of the nasal bone.Methods A retrospective chart review was performed of 356 patients who underwentreduction of a nasal bone fracture in our department from January, 2006, to July, 2011.We treated 263 patients with IOR. We assessed patients’ and doctors’ satisfaction withsurgical outcomes after IOR or CR. We evaluated the frequency of nasal bleeding owing tomucosal injury, and followed the surgical outcomes of patients who had simultaneous dorsalaugmentation rhinoplasty.Results According to the analysis of the satisfaction scores, both patients and doctors weresignificantly more satisfied in the IOR group than the CR group (P<0.05. Mucosal injury withnasal bleeding occurred much less in the IOR group (5.3% than the CR group (12.9%. Dorsalaugmentation rhinoplasty with IOR was performed simultaneously in 34 cases. Most of them(31/34 showed satisfaction with the outcomes.Conclusions IOR enables surgeons to manipulate the bony fragment directly through theendonasal incisional approach. However, we propose that CR is the proper technique forpatients under 16 and for those with comminuted nasal bone fractures because submucosaldissection in IOR can damage the growth or circulation of nasal bone.

Nasal Filters For Relief From Atopic Dermatitis Caused by Inhalants

Full Text Available Nasal filter is a simple device consisting of a net mounted in a frame made to fit inside the nostrils. These filters thus are not visible from outside. If a person uses the nasal filters the .u particulate material from the air that the person breathes gets removed and in case the person is allergic to an inhalant antigen, he stops having the allergic symptoms.

DEFF Research Database (Denmark)

Jacobi, H H; Skov, P S; Poulsen, L K

1999-01-01

BACKGROUND: Antihistamines (H1-receptor antagonists) act by competitive antagonism of histamine at H1-receptors. In addition, high concentrations of some antihistamines inhibit allergen-induced histamine release from mast cells in vitro. OBJECTIVE: The purpose of this study was to determine...... the effect of intranasal azelastine or systemic cetirizine (both potent antihistamines) on the allergen-induced release of mast-cell mediators from the human nasal mucosa in vivo. METHODS: Patients allergic to birch pollen (n = 11) and control subjects not allergic to birch pollen (n = 5) were included......, nasal allergen challenges were performed, and the number of sneezes were counted. In addition, nasal lavage fluid was collected, and the levels of mast-cell mediators (histamine and tryptase) were measured. RESULTS: The allergen challenge of patients allergic to pollen produced sneezing...

The aim of this study was to investigate the etiological role of human papilloma virus (HPV), herpes simplex virus (HSV), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), cytomegalovirus (CMV), and human herpes virus-6 (HHV-6) and -7 (HHV-7) in the occurrence of nasal polyposis. Nasal polyp samples from 30 patients with nasal polyposis and normal nasal mucosa from 10 patients without nasal polyps were obtained. DNA was extracted from tissues. Real-time polymerase chain reaction was performed for all runs. No HSV-1, HSV-2, or VZV was detected in the samples. Among the patient samples, EBV and HHV-7 DNA were detected in 18 (60%), HHV-6 was detected in 20 (66.7%), and HPV was detected in 4 (13.3%) samples. Among the controls, CMV DNA was positive in one (10%). EBV was positive in 5 (50%), HHV-6 and HHV-7 were positive in 7 (70%), and HPV was positive in 2 (20%) samples. No significant difference was found among the groups with any test in terms of positivity. The association of Herpesviridae and HPV with the pathogenesis of nasal polyps was investigated in this study and no relationship was found. Thus, these viruses do not play a significant role in the formation of nasal polyps.

Full Text Available Abstract Background Reusable nasal-spray devices are frequently used in otolaryngologic examinations, and there is an increasing concern about the risk of cross-contamination from these devices. The aim of our study was to determine, by means of microbiologic analysis, the safety of a positive-displacement or pump-type atomizer after multiple uses. Methods A reusable nasal spray bottle, pump, and tips were used in the nasal physical examination of 282 patients admitted to a tertiary otolaryngology clinic. The effectiveness of 2 different methods of prophylaxis against microbiologic contamination (the use of protective punched caps or rinsing the bottle tip with alcohol was compared with that of a control procedure. Results Although there was no statistically significant difference in positive culture rates among the types of nasal spray bottles tested, methicillin-resistant coagulase-negative staphylococci were isolated in 4 of 198 cultures. Conclusion Given these findings, we concluded that additional precautions (such as the use of an autoclave between sprays, disposable tips, or disposable devices are warranted to avoid interpatient cross-contamination from a reusable nasal spray device.

Purpose: To investigate, in a large cohort of patients, the immunophenotypic and clinical differences of nasal and extranasal extranodal nasal-type natural killer/T-cell lymphoma of the upper aerodigestive tract (UADT-NKTCL) and examine the relevance of the immunophenotype on the clinical behavior, prognosis, and treatment. Methods and Materials: A total of 231 patients with UADT-NKTCL were recruited. One hundred eighty-one patients had primary location in the nasal cavity (nasal UADT-NKTCL), and 50 patients had primary extranasal UADT-NKTCL. Results: Patients with extranasal UADT-NKTCL had more adverse clinical features, including advanced-stage disease, regional lymph node involvement, B symptoms, and poor performance status, than patients with nasal UADT-NKTCL. In addition, CD56 and granzyme B were less frequently expressed in extranasal UADT-NKTCL. The 5-year overall survival rate was 74.1% for the entire group and 76.0% for early-stage disease. The 5-year overall survival rate for extranasal UADT-NKTCL was similar or superior to that of nasal UADT-NKTCL for all disease stages (76.9% vs 73.4%, P=.465), stage I disease (75.9% vs 79.2%, P=.786), and stage II disease (83.3% vs 50.3%, P=.018). CD56 expression and a Ki-67 proliferation rate ≥50% predicted poorer survival for extranasal UADT-NKTCL but not for nasal UADT-NKTCL. Conclusions: Patients with nasal and extranasal UADT-NKTCL have significantly different clinical features, immunophenotypes, and prognosis. Extranasal UADT-NKTCL should be considered as a distinct subgroup apart from the most commonly diagnosed prototype of nasal UADT-NKTCL.

Many etiologies are held accountable for nasal septum perforations. Topical nasal drug usage, previous surgeries, trauma, nose picking, squamous cell carcinoma, some rheumatological disorders such as granulomatosis with polyangiitis (Wegener granulomatosis), some infectious diseases such as syphilis and leprosy are among the causes of the perforations. Occupational heavy metal exposures by inhalation rarely may also cause nasal septum perforation. Here, we present a 29-year-old patient without any known diseases, who is a worker at a metallic coating and nickel-plating factory, referred for investigation of his nasal cartilage septum perforation from an otorhinolaryngology clinic. The patient questioning, physical examination and laboratory assessment about rheumatic and infectious diseases were negative. There was a metallic smell in the breath during the physical examination. The analysis showed serum nickel level at 31 μg/l and urine nickel at 18 μg/l (84.11 μg/g creatinine). Other possible serum and urine heavy metal levels were within normal ranges. Nickel exposure is usually together with other heavy metals (chromium or cadmium), it is rarely alone. Nickel ingested by inhalation usually leads to respiratory problems such as reduced olfactory acuity, ulcers, septum perforation or tumors of the nasal sinuses. This case demonstrates the importance of occupational anamnesis and awareness of diagnosis. Int J Occup Med Environ Health 2017;30(6):963-967.

Full Text Available Unilateral sinus disease (USD can sometimes be difficult to accurately diagnose before surgery. The application of nasal nitric oxide (nNO for USD diagnosis and its surgical outcome in USD has not been reported in the literature. We prospectively enrolled sixty-six USD patients who underwent endoscopic sinus surgery for fungal rhinosinusitis (n = 19, chronic rhinosinusitis (CRS without nasal polyps (n = 13, CRS with nasal polyps (n = 12 and sinonasal mass lesions (n = 22. nNO levels were measured preoperatively and at three and six months postoperatively. Correlations between nNO levels and potential clinical parameters, type of disease, disease severity, and disease-related quality of life (QOL were assessed. Unlike bilateral CRS, in USD, nNO levels did not correlate with disease severity or postoperative QOL improvements. Except for fungus group, there were no differences in nNO levels between lesion and non-lesion sides in all the other groups. nNO levels on both sides were significantly elevated six months postoperatively in all groups. Fungal rhinosinusitis patients had the lowest preoperative nNO levels, and a cutoff of 239.3 ppb had the best sensitivity (79.0% and specificity (87.2% for preoperative diagnosis. While preoperative nNO levels cannot serve as an alternative marker for disease severity of USD, they were lower in fungal rhinosinusitis patients than in other USD patients and may be useful for more accurate diagnosis prior to surgery.

Infants born prematurely with respiratory distress syndrome are at high risk for complications from mechanical ventilation. Strategies are needed to minimize their days on the ventilator. The purpose of this study was to compare extubation success rates in infants treated with 2 different types of continuous positive airway pressure devices. A retrospective cohort study design was used. Data were retrieved from electronic medical records for patients in a large, metropolitan, level III neonatal intensive care unit. A sample of 194 premature infants with respiratory distress syndrome was selected, 124 of whom were treated with nasal intermittent positive pressure ventilation and 70 with bi-level variable flow nasal continuous positive airway pressure (bi-level nasal continuous positive airway pressure). Infants in both groups had high extubation success rates (79% of nasal intermittent positive pressure ventilation group and 77% of bi-level nasal continuous positive airway pressure group). Although infants in the bi-level nasal continuous positive airway pressure group were extubated sooner, there was no difference in duration of oxygen therapy between the 2 groups. Promoting early extubation and extubation success is a vital strategy to reduce complications of mechanical ventilation that adversely affect premature infants with respiratory distress syndrome.

Previous nationwide surveys of allergies in the United States have focused on nasal symptoms, but ocular symptoms are also relevant. This study determines the effects of ocular and nasal allergies on patients' lives. Telephone surveys of randomly selected U.S. households (the patient survey) and health care providers (provider survey) were conducted in the United States in 2012. Study participants were 2765 people ≥5 years of age who had ever been diagnosed with nasal or ocular allergies and 500 health care providers in seven specialties. Respondents to the patient survey reported a bimodal seasonal distribution of allergy symptoms, with peaks in March to May and September. Nasal congestion was the most common of the symptoms rated as "extremely bothersome" (39% of respondents), followed by red, itchy eyes (34%; p = 0.84 for difference in extreme bothersomeness of nasal and ocular symptoms). Twenty-nine percent of respondents reported that their or their child's daily life was impacted "a lot" when allergy symptoms were at their worst. Workers rated their mean productivity at 29% lower when allergy symptoms were at their worst (p < 0.001 compared with no symptoms). Providers reported that itchy eyes was the symptom causing most patients to seek medical treatment by pediatricians (73%), ophthalmologist/optometrists (72%), and nurse practitioners or physician assistants (62%), whereas nasal congestion was the symptom causing most patients to seek treatment from otolaryngologists (85%), allergist/immunologists (79%), and family medicine practitioners (64%). Ocular and nasal allergy symptoms substantially affected patients' lives and were comparable in their impact.

Full Text Available Objective: Most of the malignant cutaneous carcinomas are seen in the nasal region. Reconstruction of nasal defects is challenging because of the unique anatomic properties and complex structure of this region. In this study, we present our algorithm for the nasal skin defects that occurred after malignant skin tumor excisions. Material and Methods: Patients whose nasal skin was reconstructed after malignant skin tumor excision were included in the study. These patients were evaluated by their age, gender, comorbities, tumor location, tumor size, reconstruction type, histopathological diagnosis, and tumor recurrence. Results: A total of 130 patients (70 female, 60 male were evaluated. The average age of the patients was 67.8 years. Tumors were located mostly at the dorsum, alar region, and tip of the nose. When reconstruction methods were evaluated, primary closure was preferred in 14.6% patients, full thickness skin grafts were used in 25.3% patients, and reconstruction with flaps were the choice in 60% patients. Different flaps were used according to the subunits. Mostly, dorsal nasal flaps, bilobed flaps, nasolabial flaps, and forehead flaps were used. Conclusion: The defect-only reconstruction principle was accepted in this study. Previously described subunits, such as the dorsum, tip, alar region, lateral wall, columella, and soft triangles, of the nose were further divided into subregions by their anatomical relations. An algorithm was planned with these sub regions. In nasal skin reconstruction, this algorithm helps in selection the methods for the best results and minimize the complications.

Measurement with nasal scintigraphy of nasal mucociliary clearance in normal man

International Nuclear Information System (INIS)

Murai, Sumiko

1989-01-01

Nasal mucociliary function was evaluated by nasal scintigraphy in normal subjects. A microdrop of HSA or saline labelled with 99m Tc was dripped into the middle part of each middle meatus in the nasal cavity and its clearance was observed by scinticamera. The accumulated concentration of RI was determined every 30 seconds for 10 minutes. The changes of accumulated concentration were studied, and a curve of decreasing RI-counts was obtained, with the 'clearance rate' defined as 100% for the count at the initial 30 seconds and 'half time' as the time when radioactivity was reduced to one half the initial count. Nasal resistance was measured by rhinomanometry with the oscillation method. In nonsmokers, 10μl of saline was cleared (78.0±10.4%) significantly faster than 10μl of HSA (59.9±24.6%), and there was no significant difference in the clearance between 10μl and 5μl of HSA (55.9±27.7%). In smakers, the mucociliary clearance of 10μl of HSA and saline was significantly lower than in nonsmokers. The clearance of 10μl of HSA reflects a pathological state much better than that of 5μl. In nonsmokers, there is a significant negative correlation between nasal resistance and clearance rate, suggesting that the more patent the nose, the faster the mucociliary clearance. When both nostrils were closed, the clearance rate was significantly depressed. When one nostril was closed, there was no significant effect on clearance. Nasal resistance was decreased by exercise with a bicycle ergometer. Nasal mucociliary clearance was slightly decreased after exercise but not significantly so. (J.P.N.)

Acheson, E. D.; Cowdell, R. H.; Jolles, B.

1970-01-01

A survey of the incidence of nasal cancer in Northamptonshire during the period 1953 to 1967 is reported. Of the 46 patients with nasal cancer ascertained during the 15-year period 21 (19 males and 2 females) had been employed at some time in the boot and shoe industry. Five other cases diagnosed either before 1953 or after 1967 in persons who had worked in the boot and shoe industry in Northamptonshire were ascertained from various sources. The incidence of nasal cancer (all histological types considered together) was significantly higher in male boot and shoe operatives in Northamptonshire than in males of all occupational classes in the Cancer Register areas selected for comparison and in males working in other occupations in Northamptonshire. The excess incidence has recently given rise to the occurrence of between 1 and 2 new cases per annum in the Northamptonshire boot and shoe industry. The cases within the Northamptonshire industry occurred almost entirely in the relatively small number of workers who are exposed to the dust of the materials used in the manufacture of footwear. Possibly there are two carcinogenic factors in the industry—one related to the production of nasal adenocarcinoma, and the other to squamous and possibly other types of carcinoma in the nasal cavity and sinuses. This requires further study. Our best estimate of the latent period for the adenocarcinoma cases was 54·6 years, which is substantially longer than for the patients with squamous, transitional, and anaplastic tumours (41·7 years). We have no evidence to answer the question whether the facts are still present in the industrial environment, though undoubtedly the standards of hygiene in the industry has improved substantially since these men were first exposed. There is probably an increased risk of nasal adenocarcinoma in the footwear repairing industry, but this requires further study. Our evidence suggests that snuff taking should be considered as a possible contributory

Image diagnosis of nasal bone fracture

Hirota, Yoshiharu; Shimizu, Yayoi; Iinuma, Toshitaka.

1988-01-01

Twenty cases of nasal bone fractures were evaluated as to the types of fractures based upon HRCT findings. Conventional X-Ray films for nasal bones were analyzed and compared with HRCT findings. Nasal bone fractures were classified into lateral and frontal fractures. HRCT images were evaluated in three planes including upper, middle and lower portions of the nasal bone. Fractures favored males of teens. Lateral fracture gave rise to the fractures of the nasal bone opposite to the external force, loosening of the ipsilateral nasomaxillary sutures and fractures of the frontal process of the maxilla. Conventional X-Ray films were reevaluated after HRCT evaluation and indications of nasal bone fractures were determined. In addition to the discontinuity of the nasal dorsum, fracture lines parallel to and beneath the nasal dorsum and indistinct fracture lines along the nasomaxillary sutures are the indication of nasal bone fractures by conventional X-Ray films.

The use of prosthetic devices for correction of velopharyngeal insufficiency (VPI) is an alternative treatment for patients with conditions that preclude surgery and for those individuals with a hypofunctional velopharynx (HV) with a poor prognosis for the surgical repair of VPI. Understanding the role and measuring the outcome of prosthetic treatment of velopharyngeal dysfunction requires the use of tools that allow for documenting pre- and post-treatment outcomes. Experimental openings in speech bulbs have been used for simulating VPI in studies documenting changes in aerodynamic, acoustic and kinematics aspects of speech associated with the use of palatal prosthetic devices. The use of nasometry to document changes in speech associated with experimental openings in speech bulbs, however, has not been described in the literature. Objective This single-subject study investigated nasalance and nasality at the presence of experimental openings drilled through the speech bulb of a patient with HV. Material and Methods Nasometric recordings of the word "pato" were obtained under 4 velopharyngeal conditions: no-opening (control condition), no speech bulb, speech bulb with a 20 mm2 opening, and speech bulb with 30 mm2 opening. Five speech-language pathologists performed auditory-perceptual ratings while the subject read an oral passage under all conditions. Results Kruskal-Wallis test showed significant difference among conditions (p=0.0002), with Scheffé post hoc test indicating difference from the no-opening condition. Conclusion The changes in nasalance observed after drilling holes of known sizes in a speech bulb suggest that nasometry reflect changes in transfer of sound energy related to different sizes of velopharyngeal opening.

Rhinoliths are nasal stones that result from mineralisation of salts around an endogenous or exogenous nidus within the nasal cavity. They are uncommon nasal masses and usually unilateral and single, situated in the floor of the nose. The patient typically presents with nasal obstruction, facial pain and foul-smelling nasal secretion. To the best of our knowledge, the occurrence of squamous cell carcinoma with rhinolithiasis has not been previously reported in the English-language literature. In this article, we present a 63-year-old man, who had unilateral rhinolithiasis with squamous cell carcinoma within the nasal cavity.

Misato Ueda, MD

2017-09-01

Full Text Available Nasal polyps are inflammatory proliferative tumors arising from the mucosa of the nasal cavity and paranasal sinuses. Although many cases concerning nasal polyps have been reported, those involving external nasal deformities are rare. We report a case of nasal polyposis filling the nasal cavity and paranasal sinuses, leading to external nasal and facial deformities. The condition above is known as Woakes’ syndrome, which is characterized by severe recurrent nasal polyps with deformity of the nasal pyramid, leading to broadening of the nose. We performed nasal osteotomy and facial bone-shaving via the midface degloving approach, which improved the patient’s facial appearance.

Extranasopharyngeal angiofibroma of nasal septum. A controversial entity

Science.gov (United States)

Tasca, I; Ceroni Compadretti, G

2008-01-01

Summary The term extranasopharyngeal angiofibroma has been applied to vascular, fibrous nodules occurring outside the nasopharynx. The maxillary sinus is the most common site involved, while the nasal septum represents an extremely rare localization. Computerized tomography scan and magnetic resonance imaging are used to determine the tumour site and its extension. Surgical excision of the mass is the treatment of choice, and recurrence is rare. Typically, clinical characteristics of extranasopharyngeal angiofibromas do not conform with that of nasopharyngeal angiofibromas and, for this reason, these tumours must be regarded as a separate entity. Due to these different features, extranasopharyngeal angiofibromas can present a diagnostic challenge and a meticulous evaluation with a high index of suspicion is essential in establishing the correct diagnosis and treatment. We report the case of a 57-year-old female with a 1-year history of a slowly progressing right nasal obstruction due to the presence of a whitish mass adhering to the posterior nasal septum. The patient was succesfully treated surgically. Histopathological findings were compatible with a diagnosis of angiofibroma. Extranasopharyngeal angiofibroma must be taken into consideration in the differential diagnosis of nasal vascular tumours and nasal septum should be regarded as a potential, though exceptional, localization of these neoplasms.

Nasal myiasis: report of a case and literature review

Directory of Open Access Journals (Sweden)

Reyes-Romero, Karen Eliana

2016-07-01

Full Text Available Myiasis is the infection of animal or human tissues or organs by larvae of Diptera. It may affect individuals of any age, but is more common in middle-aged and elderly patients. Nasal myiasis, an infection of the nasal and paranasal cavities by such larvae, is a common disease in tropical and developing countries. Reported cases of nasal myiasis have been caused by several different species, such as Lucilia sericata in Korea and Iran, Estro ovis in Algeria and France, Lucilia cuprina and Phaenicia sericata in Malaysia, Cochliomyia hominivorax in French Guiana, Drosophila melanogaster in Turkey, Eristalis tenax in Iran and Oestrus ovis in Israel. Signs and symptoms are related to the presence and movement of the larvae, and include foreign body sensation, bloody or muco-purulent nasal discharge. Prevention may be done with insect repellent. Treatment is based on antiparasitic drugs and techniques for removal of larvae, but may include the use of prophylactic topical or systemic antibiotics for possible secondary infections. We report a case of nasal and left maxillary sinus myiasis in an elderly woman, who responded favorably to treatment.

Reconstruction of the nasal clefts is a challenging task considering the nasal anatomic complexity and their possible association with craniofacial defects. The reconstruction of these defects needs extensive amounts of soft tissue that warrant the use of forehead flaps. Often presence of cranial defects and low hairline compromise the amount of tissue available for reconstruction warrenting tissue expansion. To evaluate the efficacy of tissue expansion in reconstruction of congenital nasal clefts. 9 patients with congenital nasal clefts involving multiple sub units were taken up for nasal reconstruction with expanded forehead flaps. The average amount of expansion needed was 200 ml. The reconstruction was performed in 3 stages. Expanded forehead flaps proved to be best modality for reconstruction providing the skin cover needed for ala, columella and dorsum with minimal scarring at the donor site. Expansion of the forehead flap is a viable option for multiple sub unit reconstruction in congenital nasal cleft deformities.

To evaluate the long-term treatment outcomes in patients who underwent revision of external dacryocystorhinostomy (DCR) and nasal intubation by bicanalicular silicone tubing (BSTI) under endonasal endoscopic guidance. Data from 28 patients with recurrent dacryocystitis were retrospectively reviewed. Revision external DCR and bicanalicular nasal intubation by silicone tubing under endonasal endoscopic guidance was performed in 28 eyes of 28 patients. The patients were evaluated with respect to the reason of recurrence, time to recurrence, time to revision, duration of follow-up and surgical success. Endoscopic endonasal examination detected an osteotomy-side obstruction by the excessive granulation tissue in 24 patients (86%), nasal septal deviation in three patients (10%) and nasal polyp in one patient (4%). Recurrence occurred after a mean duration of 5.3±3.7 months following the first operation. The mean time between the first DCR operation and the revision DCR was 11.5 ± 9.3 months. After a mean follow-up of 14.9±7.8 months, the rate of anatomic success alone was 85% (24/28); the rate of subjective success was 78% (22/28). Revision external DCR and bicanalicular nasal intubation by silicone tubing under endonasal endoscopic guidance can be recommended in patients with recurrent dacryocystitis as a surgical approach that achieves satisfactory objective and subjective success rates.

The purpose of the study is to describe early predictors and to develop a prediction tool that accurately identifies the need for mechanical ventilation (MV) in pneumonia patients with hypoxemic acute respiratory failure (ARF) treated with high-flow nasal cannula (HFNC). This is a 4-year prospective observational 2-center cohort study including patients with severe pneumonia treated with HFNC. High-flow nasal cannula failure was defined as need for MV. ROX index was defined as the ratio of pulse oximetry/fraction of inspired oxygen to respiratory rate. One hundred fifty-seven patients were included, of whom 44 (28.0%) eventually required MV (HFNC failure). After 12 hours of HFNC treatment, the ROX index demonstrated the best prediction accuracy (area under the receiver operating characteristic curve 0.74 [95% confidence interval, 0.64-0.84]; Pfailure in whom therapy can be continued after 12 hours.

Chonkar, Ankita; Nayak, Usha; Udupa, N

2015-01-01

Nasal drug delivery has now been recognized as a promising route for drug delivery due to its capability of transporting a drug to systemic circulation and central nervous system. Though nasal mucosa offers improved bioavailability and quick onset of action of the drug, main disadvantage associated with nasal drug delivery is mucocilliary clearance due to which drug particles get cleared from the nose before complete absorption through nasal mucosa. Therefore, mucoadhesive polymeric approach can be successfully used to enhance the retention of the drug on nasal mucosal surface. Here, some of the aspects of the stimuli responsive polymers have been discussed which possess liquid state at the room temperature and in response to nasal temperature, pH and ions present in mucous, can undergo in situ gelation in nasal cavity. In this review, several temperature responsive, pH responsive and ion responsive polymers used in nasal delivery, their gelling mechanisms have been discussed. Smart polymers not only able to enhance the retention of the drug in nasal cavity but also provide controlled release, ease of administration, enhanced permeation of the drug and protection of the drug from mucosal enzymes. Thus smart polymeric approach can be effectively used for nasal delivery of peptide drugs, central nervous system dugs and hormones.

reconstruction. The objective of present paper was to characterize the usefulness of expanded frontal flap to repair distal nasal defects of full thickness in patients presenting a short forehead. METHODS. A descriptive and prospective study was conducted in patients presenting with nasal defects secondary to oncology surgery, traumata and other causes who underwent a nasal reconstruction using expanded frontal flap performed in the National Institute of Oncology and Radiobiology and in the "Hermanos Ameijeiras" Surgical Hospital between June,1999 and May, 2007. RESULTS. It was possible an average gain of 1,0 cm length of the expanded frontal flap regarding the oblique design without expansion, as well as the reconstruction of the cutaneous coverage in all the cases even in the more distal defects like those of the alae nasi. The closure of donor zone always as in a direct way. CONCLUSIONS. It could be possible to characterize the usefulness of expanded frontal flap in the study sample and major advantages included length increase regarding the vertical distance of forehead. There is a consensus among authors as regards its usefulness when it is prescribed and be available and that it is a alternative resource when there are not much tissue available to reconstruction of nasal defects.

Nasal Delivery of High Molecular Weight Drugs

Erdal Cevher

2009-09-01

Full Text Available Nasal drug delivery may be used for either local or systemic effects. Low molecular weight drugs with are rapidly absorbed through nasal mucosa. The main reasons for this are the high permeability, fairly wide absorption area, porous and thin endothelial basement membrane of the nasal epithelium. Despite the many advantages of the nasal route, limitations such as the high molecular weight (HMW of drugs may impede drug absorption through the nasal mucosa. Recent studies have focused particularly on the nasal application of HMW therapeutic agents such as peptide-protein drugs and vaccines intended for systemic effects. Due to their hydrophilic structure, the nasal bioavailability of peptide and protein drugs is normally less than 1%. Besides their weak mucosal membrane permeability and enzymatic degradation in nasal mucosa, these drugs are rapidly cleared from the nasal cavity after administration because of mucociliary clearance. There are many approaches for increasing the residence time of drug formulations in the nasal cavity resulting in enhanced drug absorption. In this review article, nasal route and transport mechanisms across the nasal mucosa will be briefly presented. In the second part, current studies regarding the nasal application of macromolecular drugs and vaccines with nanoand micro-particulate carrier systems will be summarised.

Full Text Available Abstract Introduction: Nasal instillation of saline solution has been used as part of the treatment of patients with upper respiratory tract diseases. Despite its use for a number of years, factors such as the amount of saline solution to be used, degree of salinity, method and frequency of application have yet to be fully explained. Objective: Review the reported outcomes of saline nasal irrigation in adults with allergic rhinitis, acute or chronic sinusitis and after functional endoscopic sinus surgery (FESS, and provide evidence to assist physiotherapists in decision making in clinical practice. Methods: A search was conducted of the Pubmed and Cochrane Library databases between 2007 and 2014. A combination of the following descriptors was used as a search strategy: nasal irrigation, nasal lavage, rhinitis, sinusitis, saline, saline solution. Results: Eight clinical trials were included, analyzed according to participant diagnosis. Conclusion: The evidence found was heterogeneous, but contributed to elucidating uncertainties regarding the use of nasal lavage in the clinical practice of physical therapy, such as the protocols used.

The forced oscillation technique (FOT) is a non-invasive pulmonary function test which is based on the measurement of respiratory impedance. Recently, promising results were obtained by the application of FOT on patients with respiratory failure and obstructive sleep apnea (OSA). By using a nasal mask instead of a mouthpiece, the influences of the nasal passage and upper shunt alter the measured mechanical impedance. In this paper, we investigated the effects of the nasal passage and mask on FOT measurements from eight healthy subjects. A method for flow correction has been developed, which contains a pressure-flow characteristics compensation of the undetermined flow leakage at the face-mask interface. Impedance calculation and parameter estimation were performed in the frequency domain using fast Fourier transform (FFT). Average nasal parameters were Rnaw=4.07 cmH2O/l/s for resistance and Lnaw=0.0183 cmH2O/l/s2 for inertance. On average, the nasal resistance corresponds to 65.85% of the total resistance.

We performed a prospective observational study in a clinical setting to test the hypothesis that prior colonization by a Staphylococcus aureus strain would protect, by colonization interference or other processes, against de novo colonization and, hence, possible endo-infections by newly acquired S. aureus strains. Three hundred and six patients hospitalized for >7 days were enrolled. For every patient, four nasal swabs (days 1, 3, 5, and 7) were taken, and patients were identified as carriers when a positive nasal culture for S. aureus was obtained on day 1 of hospitalization. For all patients who acquired methicillin-resistant S. aureus (MRSA) or methicillin-susceptible S. aureus via colonization and/or infection during hospitalization, strains were collected. We note that our study may suffer from false-negative cultures, local problems with infection control and hospital hygiene, or staphylococcal carriage at alternative anatomical sites. Among all patients, 22% were prior carriers of S. aureus, including 1.9% whom carried MRSA upon admission. The overall nasal staphylococcal carriage rate among dermatology patients was significantly higher than that among neurosurgery patients (n = 25 (55.5%) vs. n = 42 (16.1%), p 0.005). This conclusion held when the carriage definition included individuals who were nasal culture positive on day 1 and day 3 of hospitalization (p 0.0001). All MRSA carriers were dermatology patients. There was significantly less S. aureus acquisition among non-carriers than among carriers during hospitalization (p 0.005). The mean number of days spent in the hospital before experiencing MRSA acquisition in nasal carriers was 5.1, which was significantly lower than the score among non-carriers (22 days, p 0.012). In conclusion, we found that nasal carriage of S. aureus predisposes to rather than protects against staphylococcal acquisition in the nose, thereby refuting our null hypothesis.

Lascaratos, John G; Segas, John V; Trompoukis, Constantinos C; Assimakopoulos, Dimitrios A

2003-02-01

The goal of this report is to describe the therapeutic methods and surgical techniques used by Hippocrates (5th century BC) in the treatment of nasal injuries. We studied the original Greek texts of the (generally considered genuine) Hippocratic book Mochlicon and, especially, the analytical On Joints. We identified the treatments and techniques applied to the restoration of injured noses. We found that Hippocrates classified nasal injuries, from simple contusions of soft tissues to complicated fractures. Hippocrates provided detailed instructions for each case, from poultice application and bandaging to reconstruction and reshaping of the nasal bones in cases of fractures and deviation. Hippocrates' texts reflect the interest of the classical period in nasal injuries, a common enough accident in athletics. Hippocratic conservative and surgical management for each form of injury was adopted by later physicians and influenced European medicine.

The role at admission of nasal polymerase chain reaction (PCR) for patients with methicillin-resistant Staphylococcus aureus (MRSA) in guiding antibiotic therapy for lower respiratory tract infection is unknown. To determine whether nasal MRSA PCR at admission can predict the absence of MRSA in lower respiratory tract secretions. We performed a retrospective study of adult patients admitted to a large urban hospital. Patients had a nasal MRSA PCR test and a lower respiratory tract culture obtained within 48 hours of admission and the culture yielded S aureus. Sensitivity, specificity, and positive and negative predictive values. Our results showed high sensitivity (93.3%) and negative predictive value (95.2%) of nasal PCR for MRSA in the lower respiratory tract. With its high sensitivity and negative predictive value, a nasal MRSA PCR test performed within 48 hours of hospital admission could help guide the discontinuation of MRSA-directed empiric antibiotic therapy in patients who are unlikely to be infected with this organism. A prospective study is needed to confirm these findings.

Full Text Available Since nasal NK/T cell lymphoma and NK/T cell lymphoma nasal type are rare diseases, gastric involvement has seldom been seen. We report a unique case of a patient with a primary NK/T cell lymphoma nasal type of the stomach with skin involvement. The patient had no history of malignant diseases and was diagnosed with hematemesis and intense bleeding from his gastric primary site. Shortly after this event, exanthemic skin lesions appeared with concordant histology to the primary site. Despite chemotherapy, the patient died one month after the first symptomatic appearance of disease.

Effects of antihistamine on up-regulation of histamine H1 receptor mRNA in the nasal mucosa of patients with pollinosis induced by controlled cedar pollen challenge in an environmental exposure unit

Directory of Open Access Journals (Sweden)

Full Text Available In the present study, we examined the effects of antihistamine on the up-regulation of H1R mRNA in the nasal mucosa of patients with pollinosis induced by controlled exposure to pollen using an environmental exposure unit. Out of 20 patients, we designated 14 responders, whose levels of H1R mRNA in the nasal mucosa were increased after the first pollen exposure and excluded 6 non-responders. Accordingly, the first exposure to pollen without treatment significantly induced both nasal symptoms and the up-regulation of H1R mRNA in the nasal mucosa of the responders. Subsequently, prophylactic administration of antihistamine prior to the second pollen exposure significantly inhibited both of the above effects in the responders. Moreover, the nasal expression of H1R mRNA before the second pollen exposure in the responders pretreated with antihistamine was significantly decreased, as compared with that before the first pollen exposure without treatment. These findings suggest that antihistamines suppressed histamine-induced transcriptional activation of H1R gene in the nasal mucosa, in addition to their blocking effect against histamine on H1R, resulting in a decrease of nasal symptoms. These findings further suggest that by their inverse agonistic activity, antihistamines suppress the basal transcription of nasal H1R in the absence of histamine in responders.

To evaluate the effectiveness of pre-surgical nasoalveolar molding (PNAM) in patients with unilateral cleft lip nasal deformities. Methods: This was a retrospective study involving 29 patients with unilateral cleft lip and palate defects, of whom 13 were treated with palatal devices with nasal stents (PNAM group) and 16 were treated with palatal devices without nasal stents or surgical tapes (control group). Submental oblique photographs and orthodontic models were longitudinally obtained at the initial visit (T1) and immediately before (T2) and  after cheiloplasty (T3). Asymmetry of the external nose, degree of columellar shifting, nasal tip/ala nose ratio, nasal base angle, interalveolar gap, and the sagittal difference in the alveolar gap were measured. The study was conducted in the Orthodontic Clinic at Tokushima University Hospital, Tokushima, Japan between 1997 and 2012. Results: At T1, there were no significant intergroup differences in the first 4 asymmetry parameters. At T2, the PNAM group showed a significant improvement in all values compared to the control group. At T3, the PNAM group showed significant improvement in nasal asymmetry and columellar shifting. Model analysis showed significantly greater changes in the inter-alveolar gap and the sagittal difference of the alveolar cleft gap from T1 to T2 in the PNAM group. Conclusion: The use of PNAM is indispensable for pre-surgical orthodontic treatment at the early postnatal age.

Diprosopus dirrhinus, or nasal duplication, is a rare entity of partial craniofacial duplication. The case we present is the first report of diprosopus dirrhinus associated with complete cleft lip and palate. The baby was born in Cambodia at full term by normal vaginal delivery with no significant perinatal and family history. Physical examination revealed significant facial deformity due to the duplicated nose and the left complete cleft lip/palate on the right subset. There were 4 nostrils; both medial apertures including the cleft site were found to be 10-15 mm deep cul-de-sac structures without communication to the nasopharynx. The upper third of the face was notable for hypertelorism with a duplication of the soft-tissue nasion and glabella. Between the 2 nasal dorsums, there was a small cutaneous depression with a lacrimal fistula in the midline. Surgical treatment included the first stage of primary lip and nose repair and the second stage of palatoplasty. The patient was followed up at the age of 10 years showing satisfactory results for both aesthetic and functional aspects. Further management in the future will be required for the hypertelorism and nasal deformity.

Endoscopic resection of nasopharyngeal angiofibroma is less traumatic, causes less bleeding, and provides a good curative effect. Using pre-operative embolization and controlled hypotension, reasonable surgical strategies and techniques lead to successful resection tumors of a maximum Andrews-Fisch classification stage of III. To investigate surgical indications, methods, surgical technique, and curative effects of transnasal endoscopic resection of nasopharyngeal angiofibroma, this study evaluated factors that improve diagnosis and treatment, prevent large intra-operative blood loss and residual tumor, and increase the cure rate. A retrospective analysis was performed of the clinical data and treatment programs of 23 patients with nasopharyngeal angiofibroma who underwent endoscopic resection with pre-operative embolization and controlled hypotension. The surgical method applied was based on the size of tumor and extent of invasion. Curative effects were observed. No intra-operative or perioperative complications were observed in 22 patients. Upon removal of nasal packing material 3-7 days post-operatively, one patient experienced heavy bleeding of the nasopharyngeal wound, which was treated compression hemostasis using post-nasal packing. Twenty-three patients were followed up for 6-60 months. Twenty-two patients experienced cure; one patient experienced recurrence 10 months post-operatively, and repeat nasal endoscopic surgery was performed and resulted in cure.

Primary extracranial meningiomas (PEMs) originating from the nasal septum are extremely rare, as are extracranial metastases of meningiomas. A 44-year-old male presented with a 2-month history of left-side nasal obstruction and frequent episodes of epistaxis. A friable mass originating from the nasal septum was resected completely via an endoscopic endonasal approach. According to WHO criteria, the tumor was diagnosed as an atypical meningioma radiologically and histopathologically. Two years later, a tumor recurred at the primary site with the same histopathological findings, and the patient was given local external radiotherapy (6840 cGy in 38 fractions). Two months after this local recurrence, a left anterior chest wall mass and a left parietal area scalp mass were observed. The subcutaneous mass was resected and showed histological evidence of malignant transformation. Several months after the last operation, the patient died. We describe the clinical, radiological, and bio-pathological features of this unique case and review the literature on atypical PEMs originating in the nasal septum. To our knowledge, this is the first reported case of an atypical PEM originating from the nasal septum that recurred with malignant transformation and extracranial metastasis

Local IgE production in nonatopic nasal polyposis.

LENUS (Irish Health Repository)

Sheahan, Patrick

2012-02-01

INTRODUCTION: Chronic rhinosinusitis with nasal polyposis (CRSwNP) represents an eosinophilic T-helper 2 inflammatory response. Local production of IgE within nasal polyps (NPs) has been demonstrated, suggesting a role for local IgE in the pathogenesis of NP in atopic CRS patients. We hypothesized that local IgE specific to inhalant allergens may also play a role in the genesis of NP in nonatopic CRS patients. METHODS: Sinus and inferior turbinate tissue was obtained from nonatopic CRSwNP patients (n = 7), chronic rhinosinusitis without nasal polyps (CRSsNP) patients (n = 15), and healthy controls (n = 9) at the time of surgery. ImmunoCAP analysis (Phadia AB, Portage, MI) for 14 common inhalant antigens was performed on tissue homogenates to determine the antigen-specific response. RESULTS: Total IgE levels did not differ in sinus or turbinate tissue between CRSwNP, CRSsNP, or control patients. CRSwNP sinus tissue had higher levels of specific IgE for cockroach and plantain (p = .03) than other groups and elevated Alternaria IgE levels when compared with CRSsNP sinus tissue (p < .05). No significant differences were found for any of the other antigen-specific IgE levels. Fifty-seven percent of CRSwNP polyps demonstrated a polyclonal IgE response, whereas the other 43% had no demonstrable antigen-specific IgE. In contrast, only 17% of CRSsNP patients demonstrated a polyclonal response within sinus tissue, whereas 67% had no detectable antigen-specific IgE. There was no significant difference in levels of IgE in inferior turbinate tissue between the groups (p > .05). CONCLUSIONS: Localized mucosal IgE specific to common inhalant allergens appears to play a role in a subset of CRSwNP patients without evidence of systemic atopy.

Rosen, H M

1988-02-01

Forty-one patients undergoing Le Fort I osteotomy for superior and/or anterior repositioning of the maxilla were prospectively studied for changes in soft-tissue morphology of the nasomaxillary region. Nasal parameters studied were changes in interalar rim width and nasal tip projection. It was observed that alar rim width increases with anterior and/or superior repositioning of the maxilla, but increases in nasal tip projection occur only when there is an anterior vector of maxillary movement. These nasal changes could not be quantitatively correlated to magnitude of maxillary movement. Lip changes studied were the horizontal displacement at the vermilion border and subnasale versus that of the incisal edge and point A, respectively, when the maxilla is sagittally advanced and the vertical shortening of the lip versus that of the incisal edge when the maxilla is shortened. Using linear regression analysis, horizontal displacement of the upper lip at the vermilion border was 0.82 +/- 0.13 mm for every 1 mm of maxillary advancement at the incisal edge (p less than 0.001) and 0.51 +/- 0.13 at the subnasale for every 1 mm of maxillary advancement at point A (p less than 0.001). Eighty percent of patients undergoing maxillary intrusive procedures had lip shortening ranging from 20 to 50 percent of the vertical maxillary reduction. Surprisingly, no statistically significant correlation could be demonstrated for lip shortening versus extent of vertical maxillary reduction. Previous literature in disagreement with these findings is discussed. Guidelines for treatment planning utilizing these data are suggested.

The sinonasal involvement is one of the most common manifestations in cystic fibrosis. Data show a high incidence of chronic rhino sinusitis in these patients. Although it has been found radiographic opacification of the sinus in more than 90% of cases, few are symptomatic. So that, it is difficult to recognize nasossinusal disease in patients with cystic fibrosis. Questionnaire, nasal endoscopy and CT-scan are very important methods in this approach. Aim: to evaluate the diagnosis of chronic rhino sinusitis in patients with cystic fibrosis by anamnesis, nasal endoscopy and CT-scan and compare those results.Study Design: Clinical prospective. Material and method: evaluation of 34 patients - older than 6 years and with a confirmed diagnoses of cystic fibrosis - by anamnesis (questionnaire), nasal endoscopy (score Lund-Kennedy) and CT-scan (score Lund-Mackay). Results: chronic rhino sinusitis was confirmed in: 20,58% of cases by the questionnaire, 73,52% of the cases by the nasal endoscopy and in 93,54% of the cases by the CT-scan. The results showed significant differences. The correlation between nasal endoscopy score (Lund-Kennedy score) and CT-scan score (Lund-Mackay score) was statistically significant. Conclusion: the diagnosis of chronic rhino sinusitis was statistically different between the three methods. It was higher in imaging analysis and lower in questionnaire. The nasal endoscopy is an excellent method to evaluate nasossinusal disease in cystic fibrosis. (author)

Cellular changes in tears associated with keratoconjunctival responses induced by nasal allergy.

Pelikan, Z

2014-04-01

Allergic keratoconjunctivitis occurs in a primary form, caused by an allergic reaction localized in the conjunctiva, and in a secondary form, induced by an allergic reaction originating in the nasal mucosa. Various hypersensitivity mechanisms involved in the keratoconjunctivitis forms result in different keratoconjunctival response types. To investigate the cytologic changes in tears during the secondary immediate (SIKCR), late (SLKCR), and delayed (SDYKCR) keratoconjunctival responses. In 61 patients, comprising 20 SIKCRs, 23 SLKCRs, and 18 SDYKCRs, nasal provocation tests (NPTs) with allergens and 61 phosphate-buffered control challenges were repeated and supplemented with cell counting in the tears. The SIKCR (Ptears. The SLKCR (Ptears. The cells, except mast, epithelial and goblet cells, displaying no intracellular changes, migrated probably from the conjunctival capillaries, in response to the factors released during the primary allergic reaction in the nasal mucosa and subsequently penetrating into the conjunctiva. These results demonstrate a causal role of nasal allergy and diagnostic value of NPT combined with recording of ocular features and cellular profiles in tears in some keratoconjunctivitis patients.

2017-08-01

The prediction of detailed flow patterns in human nasal cavities using computational fluid dynamics (CFD) can provide essential information on the potential relationship between patient-specific geometrical characteristics of the nasal anatomy and health problems, and ultimately led to improved surgery. The complex flow structure and the intricate geometry of the nasal cavities make achieving such goals a challenge for CFD specialists. The need for experimental data to validate and improve the numerical simulations is particularly crucial. To this aim an experimental set-up based on Stereo PIV and a silicon phantom of nasal cavities have been designed and realized at Politecnico di Milano. This work describes the main features and challenges of the set-up along with some preliminary results.

The bleeding points and its correlation with age distribution, surgical techniques as well as its effects were studied retrospectively in 92 patients, in whom the bleeding points were not found by routine nasal endoscopy and the hemorrhage was not controlled with standard nasal packing. The bleeding points were found in the following different sites: superior wall of inferior nasal meatus (56.5%, 52/92), olfactory cleft of nasal septum (27.2%, 25/92), posterosuperior wall of middle nasal meatus (8.7%, 8/92) and uncertain (7.6%, 7/92). The results showed that the bleeding points had correlation with age. Epistaxis was well controlled by electrocoagulation in 83 cases, gelfoam packing in 8 cases, and transcatheter maxillary artery embolization in 1 case. There were no complications during a followed-up for 1 - 3 months after management. Among the 92 cases, the numbers of treatment needed to stop bleeding were 82 cases (89.1%) after 1 time of treatment, 9 cases (9.8%) after 2 times and in one case (1.1%) after 4 times. Endoscopy combined with displacement of the middle and inferior turbinate gives good visualization and direct management of the deeply-sited bleeding points, which were difficult in localization. The combined method provides an effective and safe way to control intractable epistaxis.

Full Text Available Rhinoliths are mineralised foreign bodies in the nasal cavity that are a chance finding at anterior rhinoscopy. Undiscovered, they grow appreciably in size and can cause a foul-smelling nasal discharge and breathing problems. Giant nasal stones are now a very rare occurrence, since improved diagnostic techniques, such as endoscopic/microscopic rhinoscopy, now make it possible to identify foreign bodies at an early stage of development. We report the case of a 37-year-old patient who, at the age of 5-6 years, introduced a foreign body, probably a stone, into his right nasal cavity. On presentation, he complained of difficulty in breathing through the right nostril that had persisted for the last 10 years. For the past four years a strong fetid smell from the nose had been apparent to those in his vicinity. Under general anaesthesia, the stone was removed in toto from the right nasal cavity. The possible genesis of the rhinolith is discussed, our case compared with those described in the literature, and possible differential diagnoses are considered.

Underrotation of the nasal tip with narrow nasolabial angle is a common nasal deformity that leads to a long nose appearance, named drooping nose. In these patients, there are various techniques described to correct droopy tip and to achieve a desirable nasal tip rotation such as lateral crural steal, lateral crural overlay, tongue-ingroove, columellar strut graft, tip rotation sutures, cephalic trimming, and others. In this study, the effects of tongue-in-groove (TIG) and columellar strut graft (CS) and the contribution of cap graft on nasal tip rotation and projection were evaluated. Twenty-eight consecutive patients who underwent open approach rhinoplasty by the same senior author (ULD) between January 2015 and December 2016 with the diagnosis of septonasal deformity and droopy nasal tip were included. In 9 of these patients nasal tip was constructed with strut graft, in 6 patients with both strut and cap grafts, in 6 patients with TIG technique and in 7 patients with both TIG and cap graft. Standardized right lateral images were taken preoperatively and 6 months postoperatively to use for further assessments. The nasal tip rotation was evaluated by measuring nasolabial angle (NLA) and the nasal projection (NP) was evaluated by using the Goode method. Finally, the postoperative values of NLA and NP at the 6th month were compared with preoperative recorded values in between groups. Each group showed increase at nasal projection; however, significance was present only in CS graft and TIG groups (P=0.011 and P=0.027 relatively). Each 4 groups showed significant increase in nasal tip rotation. In addition, the comparison of percent changes between preoperative and postoperative NP and NLA revealed no difference (P=0.56 and P=0.431 relatively). In conclusion, the authors argued that TIG and CS graft techniques are both reliable methods to correct droopy nasal tip and using additional cap graft over dome area when required is safe and useful.

Full Text Available Abstract Background Aim of the study was to determine the clinical efficacy of a new antiseptic liquid soap (Stellisept® scrub, based on the combination of undecylenamidopropyltrimonium methosulphate (4% and phenoxyethanol (2%, for eradication of MRSA among colonized patients who do not receive antibiotic therapy. Methods Over two years 50 MRSA patients in 6 hospitals were observed. Treatment was defined as the daily application of Stellisept scrub for the antiseptic body and hair wash (at least 60 s in combination with nasal mupirocin. A treatment cycle was a minimum of 5 days treatment. Screening was carried out at least 48 h after the treatment cycle was finished, with 24 h between each of the requested three or more samplings, which included the nasopharynx, groin, axilla, perineum and other MRSA-positive skin areas. Results Fifteen cases were retrospectively excluded (lack of outcome documentation, concomitant antibiotic therapy, open wounds. All 35 patients had colonization with MRSA before antiseptic treatment on the skin, in the groin (80%, the axilla (25.7%, the perineum (20% or other skin areas (14.3%. Colonization at more than one skin sites was found in 34.3%. Nasal colonization was found in 21 of 28 patients (75%, 7 patients were without nasal screening prior to the antiseptic treatment. After one treatment cycle MRSA was eradicated in 25 patients (71.4%, after a second cycle the total eradication rate was 91.4%, after a third cycle the rate increased to 94.2%. No patient discontinued the antiseptic treatment due to dermal intolerance of the product. Conclusions Progressive eradication of MRSA carriage was observed with the antiseptic soap and mupirocin. The eradication rate was not biased by concomitant antibiotic treatment, screening during treatment or lack of evidence for colonization in contrast to other studies with other preparations.

Full Text Available The aim of this study was to determine the nasal parameters in the population of central Serbia and to compare them with those determined in earlier studies in different populations. The research was conducted on 496 randomly selected persons (262 males and 234 females, aged 18-65 years. The measured parameters were nasal height and nasal breadth and the standard spreading caliper with scale was used for measurements. There were significant differences in the nasal parameters between male and female subjects. The nasal breadth was 34.72 mm in females, and in the male population it was 36.7 mm. The mean values of nasal height were 52.6 mm and 54.32 mm in females and males, respectively. The nasal index in females and males was 66.01 and 67.56, respectively, and the mean value of the nasal index of all respondents was 66.78. After conducting the research it was concluded that the dominant nasal type in the population of the central part of Serbia is leptorrhine. The present study showed the existence of sexual dimorphism in nasal morphology. The data obtained in our study may be useful in anthropological and forensic research, as well as in cosmetic planning and reconstructive surgery.

Analgesic intolerance (AI) appears in approximately 1 % of the general population. The triad of bronchial asthma, nasal polyposis, and analgesic intolerance is called analgesic-induced asthma (AIA). These patients are frequently referred to adult allergy clinics for preoperative evaluation for possible analgesic cross reactivity and intolerance to anesthetic agents. To determine allergic problems related to anesthesia and postoperative pain management in AI patients with and without asthma. The medical records of 45 patients who had been diagnosed with AI between January 1991 and December 2002 in the adult allergy unit and who underwent surgery in the same hospital in the last 4 years were retrospectively analyzed. The mean age of the patients was 44.4 13.4 years and 30 (66.6 %) were female. Thirty-six (80 %) had AIA, 34 (75.6 %) had persistent allergic rhinitis and 21 (46.7 %) had nasal polyps. Fifty-one surgical procedures were performed in 45 patients, in whom ear, nose and throat surgery was the main procedure (64.7 %). Anesthesia was induced with propofol, fentanyl, and vecuronium and was maintained by sevoflurane or isoflurane. Fentanyl was used for early postoperative pain relief. No complications appeared in relation to anesthesia or early pain management except in a 44-year-old AIA woman who had a reaction in the postoperative period after receiving an inappropriate analgesic. None of the patients had anesthesia-related allergic problems. Atropine and diazepam in the premedication, propofol and fentanyl during induction, muscle relaxation facilitation by vecuronium, and sevoflurane or isoflurane for maintenance seem to be a safe general anesthetic choice for analgesic intolerant patients with and without asthma.

The present study aimed to evaluate the potential correlations between objective measurements of nasal function and self-assessed nasal symptoms or clinical findings at nasal examination among adults treated for unilateral cleft lip and palate (UCLP), respectively. All UCLP patients born between 1960 and 1987 (n = 109) treated at a tertiary referring center were invited. Participation rate was 76% (n = 83) at a mean of 37 years after the initial surgery. All participants completed the same study protocol including acoustic rhinometry (AR), rhinomanometry (RM), anterior rhinoscopy, and questionnaires regarding self-experienced nasal symptoms. A reduced volume of the anterior nasal cavity on the operated side (measured by AR) correlated to an expressed wish by the patient to change the function of the nose. A similar correlation was seen for the minimal cross-sectional area of anterior nasal cavity on the operated side. Furthermore, correlations were found between smaller volume and area of nasal cavity and a greater frequency of nasal obstruction. No further correlations were found. Objective measurements partly correlate to the clinical picture among adults treated for UCLP. However, these need to be combined with findings at clinical examination and patient self-assessment to represent the complete clinical picture.

Full Text Available Introduction. Low levels of nasal NO have been associated with increased propensity to rhinosinusitis and respiratory tract infections. Our objective was to describe nasal NO levels in HIV-infected individuals versus healthy controls and determine possible risk factors for reduced nasal NO levels. Materials and Methods. HIV-infected individuals and healthy controls were recruited. Participants underwent nasal NO testing by standardized methods using a CLD88 chemiluminescence analyzer and completed the Sinonasal Outcome Test-20 (SNOT-20 on symptoms of rhinosinusitis. Results. Participants included 41 HIV-infected individuals with suppressed VL on antiretroviral therapy (ART group, 5 HIV-infected individuals with detectable VL off ART (viremic group, and 12 healthy controls (HC group. Mean nasal NO level was 253 (±77 nL/min in the ART group, 213 (±48 nL/min in the viremic group, and 289 (±68 nL/min in the HC group (p=0.133; ANOVA. There was no correlation between nasal NO level and VL in viremic individuals (r=-0.200; p=0.747. Differences were observed in mean total points on the SNOT-20 which were 19 (±16/100, 18 (±26/100, and 4 (±4/100 in the ART, viremic, and HC groups, respectively (p=0.013; ANOVA. Conclusion. Healthy individuals, HIV patients on ART, and viremic individuals off ART display similar nasal NO levels. However, rhinosinusitis symptoms remain prominent despite ART-treatment.

The aim of this study was to describe an outbreak of Burkholderia stabilis colonization among patients in a nasal ward. Multilocus sequence typing (MLST) was used for the molecular typing of B. stabilis isolates. Microbiological records were reviewed to delineate the colonization outbreak period. One hundred seventy-one cultures of environment and equipment samples from the nasal ward were performed to trace the source of contamination. Infection control measures were taken in order to end the outbreak. All B. stabilis isolates were identified as a new MLST type, ST821. A total of 53 patients carried this B. stabilis in the nasal ward between March and September 2013, which was defined as the outbreak period. The source of the colonization was not determined because all environment cultures were negative for Burkholderia cepacia complex. No further B. stabilis carriers have been found in the ward since the implementation of interventions. Attention must be paid to asymptomatic colonization in order to identify outbreaks early.

Ipratropium bromide (IB) has been found to reduce secretions in the upper respiratory tract; this is accomplished through competitive inhibition of acetylcholine at muscarinic receptors that control rhinorrhea production. This study compared the safety and efficacy of IB with placebo in the symptomatic relief of rhinorrhea in patients with the common cold. Human subjects with symptoms of a common cold, primarily rhinorrhea, were enrolled and treated with either IB (84 micrograms/nostril) or placebo; each was administered as two sprays per nostril, four times a day, for 4 days. Primary efficacy analyses were in-clinic measurements of nasal discharge weights over a 3-hour period after administration on days 1 and 2 and assessment of rhinorrhea symptoms by use of a subjective patient-completed visual analog rating scale. IB significantly reduced rhinorrhea an average of 18% over placebo for days 1 and 2 (p = 0.01). Visual analog scale scores showed an average improvement in rhinorrhea of 22% over placebo (p = 0.001). When patients with relatively minor rhinorrhea (baseline weight of nasal discharge < or = 1.0 gm) were excluded, IB produced an average reduction in nasal discharge of 23% over placebo for days 1 and 2 (p = 0.003).

Full Text Available Introduction. Plasmacytomas are malignant tumors characterized by abnormal monoclonal proliferation of plasma cells. They originate in either bone - solitary osseous plasmacytoma, or in soft tissue - extramedullary plasmacytoma (EMP. EMP represents less than 1% of all head and neck malignancies. Case report. We presented a case of EMP of the nasal septum in a 44-year-old male who had progressive difficulty in breathing through the nose and frequent heavy epistaxis on the right side. Nasal endoscopy showed dark red, soft, polypoid tumor in the last third of the right nasal cavity arising from the nasal septum. The biopsy showed that it was plasmacytoma. Bence Jones protein in the urine, serum electrophoresis, bone marrow biopsy, skeletal survey and other screening tests failed to detect multiple myeloma. This confirmed the diagnosis of EMP. The mass was completely removed via an endoscopic approach, and then, 4 week later, radiotherapy was conducted with a radiation dose of 50 Gray. No recurrence was noted in a 3-year follow- up period. Conclusion. EMP of the nasal cavity, being rare and having long natural history, represents a diagnostic and therapeutic challenge for any ear, nose and throat surgeon. Depending on the resectability of the lesion, a combined therapy is the accepted treatment.

Full Text Available Background and Aim : Nasalization of a vowel refers to the addition of nasal resonance to the vocal tract transfer function. Also, vowel nasalization occurs because of coarticulation. Coupling of the nasal resonating space to the oropharyngeal cavity alters the vocal tract formants in complex ways. The purpose of this study was to investigate the effect of nasalization on /a/ vowel formants in before and after nasal consonant.Methods: In current cross-sectional study, voice samples of 60 normal children ranging the age of four-nine years were investigated. Participants were asked to repeat / ʔ ama/ three times and vowel /a/ after presentation of an auditory model. Then, obtained samples were analyzed using Praat 5.3.13 . Average of F0, F1, F2 and F3 were calculated for /a/ comes before and after /m/ in production of / ʔ ama/ over three trials.Results: There were statistically significant differences of F1, F2 and F3 between / a/ which proceeds nasal consonant and /a/ follows nasal consonant , the before nasal consonant /a/ versus single /a/ and the after nasal consonant /a/ versus single /a/ (p=0.001 for all.Conclusion : F1, F2 and F3 in /a/ before nasal consonant affected by anticipatory nasal coarticulation and in /a/ after nasal consonant affected by carry-over nasal coarticulation . This study showed nasal coarticulation and nasalization result in decreasing F1, F2 and F3 in /a/ vowel.

Foda, Hossam M T

2005-02-01

The deviated nose represents a complex cosmetic and functional problem. Septal surgery plays a central role in the successful management of the externally deviated nose. This study included 260 patients seeking rhinoplasty to correct external nasal deviations; 75 percent of them had various degrees of nasal obstruction. Septal surgery was necessary in 232 patients (89 percent), not only to improve breathing but also to achieve a straight, symmetrical, external nose as well. A graduated surgical approach was adopted to allow correction of the dorsal and caudal deviations of the nasal septum without weakening its structural support to the dorsum or nasal tip. The approach depended on full mobilization of deviated cartilage, followed by straightening of the cartilage and its fixation in the corrected position by using bony splinting grafts through an external rhinoplasty approach.

Full Text Available Staphylococcus aureus nasal carriers undergoing hemodialysis (HD through tunneled cuffed catheters (TCCs form a high-risk group for the development of catheter-related bloodstream infections (CRBSI and ensuing morbidity. The efficacy of antibiotic-locks on the outcomes of TCCs among S. aureus nasal carriers has not been studied earlier. Persistent nasal carriage was defined by two or more positive cultures for methicillin-susceptible (MSSA or methicillin-resistant (MRSA S. aureus of five standardized nasal swabs taken from all the participants dialyzed at a large out-patient HD center affiliated to a tertiary care hospital. Of 218 participants, 82 S. aureus nasal carriers dialyzed through TCCs (n = 88 were identified through April 2005 to March 2006 and randomized to two groups. Group I comprised of 39 nasal carriers who had TCCs (n = 41 "locked" with cefotaxime/heparin while group II included 43 patients with TCCs (n = 47 filled with standard heparin. The CRBSI incidence and TCC survival at 365 days were statistically compared between the two groups. A significantly lower CRBSI incidence (1.47 vs. 3.44/1000 catheter-days, P <0.001 and higher infection-free TCC survival rates at 365 days (80.5 vs. 40.4%, P <0.0001 were observed in the cefotaxime group compared with the stan-dard heparin group. However, no significant difference in MRSA-associated CRBSI incidence was observed between the two groups. Cefotaxime-heparin "locks" effectively reduced CRBSI-incidence associated with gram-positive cocci, including MSSA, among S. aureus nasal carriers. There remains a compelling requirement for antibiotic-locks effective against MRSA.

Nasal expiratory resistive valves (Provent ® ) have been proposed as novel therapy for obstructive sleep apnea. We compared pressure measurements from a standard nasal pressure catheter used to assess nasal airflow during sleep with those from nasal expiratory resistive device with attached proprietary nasal pressure cannula. Nasal pressure cannula or Provent ® + proprietary nasal pressure cannula were attached to a bench model of human anterior nares and nasal passages, and pressure measured (P). Respiratory airflows generated by a subject breathing were applied to rear of model and airflow ( V-dot ) measured via pneumotachograph. Airflow amplitude (Δ V-dot ) was plotted against pressure amplitude (ΔP). Hypopnoea detection (<50% Δ V-dot ) sensitivity and specificity was tested by expressing ΔP in terms of two reference breaths: reference breath 1, Δ V-dot 0.55 L s −1  = 100%; and reference breath 2, Δ V-dot 0.45 L s −1  = 100%. ΔP/Δ V-dot relationships were linear for Δ V-dot  ≤ 0.55 L s −1 ; ΔP = 0.37ΔV + 0.16 (nasal pressure cannula), ΔP = 2.7ΔV + 0.12 (Provent ® + proprietary nasal pressure cannula); both R 2  > 0.65, p < 0.0001; p < 0.0001 for between slope difference). For nasal pressure cannula, specificity of hypopnoea detection differed between reference breaths one and two (80.2% and 40.0%, respectively), and Provent ® + proprietary nasal pressure cannula (30.3% and 74.2%, respectively). Quantification of airflow obstruction in the presence of Provent ® + proprietary nasal pressure cannula is greatly influenced by the reference breath chosen to determine a reduction in nasal airflow. Reported variability in therapeutic response to nasal expiratory resistive devices may relate to differences in measurement technique specificity used to quantify the severity of sleep disordered breathing.

Lara-Sánchez, Hugo; Álvarez Nuño, Candelas; Gil-Carcedo Sañudo, Elisa; Mayo Iscar, Agustín; Vallejo Valdezate, Luis Ángel

Prospective study of patients with nasal obstruction (NO) in order to measure therapeutic success by anterior active rhinomanometry (AAR), Nasal Obstruction Symptom Evaluation (NOSE) scale and Visual Analogue Scale (VAS) and to establish the correlation between these tests. Patients with NO, on whom we performed an AAR, NOSE and VAS scales at baseline and after medical treatment (topical nasal steroid) or surgery (septoplasty, turbinoplasty or septoplasty and turbinoplasty). The nasal flow obtained by the AAR and the score of both subjective scales (NOSE and VAS) were compared and analyzed. A total of 102 patients were included in the study. Surgical treatment resulted in statistically significant differences with the AAR and the subjective scales. While in patients with medical treatment there was an increase in the AAR nasal flow but without statistical significance (P=.1363). The correlation between the AAR, the NOSE and VAS scales was measured finding a strong correlation between the NOSE and VAS scales only (r=.83327). The patients with NO treated surgically have better results when these are evaluated by AAR or with subjective scales. There is no significant correlation between AAR, NOSE and VAS scales, this is considered to be because the AAR and subjective scales are complementary and measure different aspects of NO. The AAR and subjective scales are useful tools to be used together for the follow up of patients with NO.

Vikas Aggarwal

2016-01-01

Full Text Available Facial defects resulting from neoplasms, congenital abnormalities or trauma can affect the patient esthetically, psychologically, and even financially. Surgical reconstruction of large facial defects is sometimes not possible and frequently demands prosthetic rehabilitation. For success of such prosthesis, adequate replication of natural anatomy, color matching and blending with tissue interface are important criteria. Variety of materials and retention methods are advocated to achieve a functionally and esthetically acceptable restoration. Silicones are the most commonly used materials because of flexibility, lifelike appearance and ability to be used in combination with acrylic resin which is hard, provides body and helps in achieving retention to the prosthesis by engaging mechanical undercuts. Furthermore, the acrylic portion can be relined easily, thus helping comfortable wear and removal of the prosthesis by patient without traumatizing nasal mucosa. This case report describes time saving and cost effective prosthetic rehabilitation of a patient with total nasal defect using custom sculpted nasal prosthesis made up of silicone elastomer and acrylic resin, which is retained by engaging mechanical undercut and use of biocompatible silicone adhesive.

2010-01-01

A new protocol for making an immediate provisional eyeglasses-supported nasal prosthesis is presented that uses laser scanning, computer-aided design/computer-aided manufacturing procedures, and rapid prototyping techniques, reducing time and costs while increasing the quality of the final product. With this protocol, the eyeglasses were digitized, and the relative position of the nasal prosthesis was planned and evaluated in a virtual environment without any try-in appointment. This innovative method saves time, reduces costs, and restores the patient's aesthetic appearance after a disfiguration caused by ablation of the nasal pyramid better than conventional restoration methods. Moreover, the digital model of the designed nasal epithesis can be used to develop a definitive prosthesis anchored to osseointegrated craniofacial implants.

Les perforations de la cloison nasale constituent une pathologie fréquente en ORL. Leurs causes sont multiples et restent dominées par les traumatismes chirurgicaux. Les étiologies infectieuses et notamment la tuberculose sont rares. Nous présentons le cas d'une patiente ayant bénéficié d'une méatotomie bilatérale et chez laquelle une perforation de la cloison nasale a été découverte lors d'un examen systématique à un an de son intervention. D'abord considérée comme une complication de la chirurgie, la biopsie des berges de la perforation a permis de déterminer son origine tuberculeuse. La présentation clinique des perforations de la cloison nasale n'est pas spécifique. Elles sont souvent asymptomatiques et de découverte fortuite. Les traumatismes notamment chirurgicaux sont le plus siuvent en cause. L′orogine tuberculeuse resta très rare. Le diagnostic de certitude de tuberculose repose sur la biopsie des berges de cette perforation. Le but de ce travail est de mettre en avant l'intérêt de la biopsie dans le diagnostic de la tuberculose de la cloison nasale. Cette biopsie doit être systématique même en cas d'antécédents de chirurgie endonasale qui est le plus souvent en cause dans les perforations de la cloison nasale. PMID:24932334

In parallel with technological developments, small size but strong magnets are commonly used in modern devices. In terms of foreign body injuries, magnet injuries are quite rare. However, due to their unique characteristics, there are some difficulties in their management. The magnetic field generated by the magnet affects the surgical instruments and make treatment difficult. In this case report, a nasal injury due to neodymium magnet and our alternative approach for its management was reported.

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 cure rate for unresectable malignancies of the nasal cavity and paranasal sinuses is low. Because irradiation with proton beams, which are characterized by their rapid fall-off at the distal end of the Bragg peak and sharp lateral penumbra, depending on energy, depth, and delivery, provide better dose distribution than X-ray irradiation, proton beam therapy (PBT) might improve treatment outcomes for conditions located in proximity to risk organs. We retrospectively analyzed the clinical profile of PBT for unresectable malignancies of the nasal cavity and paranasal sinuses. Methods and Materials: We reviewed 39 patients in our database fulfilling the following criteria: unresectable malignant tumors of the nasal cavity, paranasal sinuses or skull base; N0M0 disease; and treatment with PBT (>60 GyE) from January 1999 to December 2006. Results: Median patient age was 57 years (range, 22-84 years); 22 of the patients were men and 17 were women. The most frequent primary site was the nasal cavity (n = 26, 67%). The local control rates at 6 months and 1 year were 84.6% and 77.0%, respectively. With a median active follow-up of 45.4 months, 3-year progression-free and overall survival were 49.1% and 59.3%, respectively. The most common acute toxicities were mild dermatitis (Grade 2, 33.3%), but no severe toxicity was observed (Grade 3 or greater, 0%). Five patients (12.8%) experienced Grade 3 to 5 late toxicities, and one treatment-related death was reported, caused by cerebrospinal fluid leakage Grade 5 (2.6%). Conclusion: These findings suggest that the clinical profile of PBT for unresectable malignancies of the nasal cavity and paranasal sinuses make it is a promising treatment option.

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.

The major improvement in burn therapy is likely to focus on the early management of hemodynamic and respiratory failures in combination with an aggressive and early surgical excision and skin grafting for full-thickness burns. Immediate burn care by first care providers is important and can vastly alter outcomes, and it can significantly limit burn progression and depth. The goal of prehospital care should be to cease the burning process as well as prevent future complications and secondary injuries for burn shock. Identifying burn patients appropriate for immediate or subacute transfer is an important step in reducing morbidity and mortality. Delays in transport to Burn Unit should be minimized. The emergency management follows the principles of the Advanced Trauma Life Support Guidelines for assessment and stabilization of airway, breathing, circulation, disability, exposure and environment control. All patients with suspected inhalation injury must be removed from the enclosure as soon as possible, and immediately administer high-flow oxygen. Any patient with stridor, shortness of breath, facial burns, singed nasal hairs, cough, soot in the oral cavity, and history of being in a fire in an enclosed space should be strongly considered for early intubation. Fibroscopy may also be useful if airway damage is suspected and to assess known lung damage. Secondary evaluation following admission to the Burn Unit of a burned patient suffering a severe thermal injury includes continuation of respiratory support and management and treatment of inhalation injury, fluid resuscitation and cardiovascular stabilization, pain control and management of burn wound.

Chronic rhinosinusitis with and without nasal polyps (CRSwNP and CRSsNP) and antrochoanal polyps (ACP) are different upper airway inflammation phenotypes with different pathomechanisms. In order to understand the development of tissue edema, the present study aimed to evaluate lymphatic vessel density in CRSsNP, CRSwNP and ACP. 120 retrospective nasal and maxillary sinus specimens were stained immunohistochemically with a von Willebrand factor polyclonal antibody recognizing vascular and lymphatic endothelium, and with a podoplanin monoclonal antibody recognizing lymphatic endothelium. Vessels were studied by microscopy in a blinded fashion, and the vessel density and the relative density of lymphatic vessels were calculated. Patient characteristic factors and follow-up data of in average 9 years were collected from patient records. In the nasal cavity, the low absolute and relative density of vessels and of lymphatic vessels was associated with CRSwNP and ACP tissues compared to control inferior turbinate. This was observed also in the inflammatory hotspot area. In the maxillary sinus, lower absolute and relative density of lymphatic vessels associated with the CRSwNP phenotype. High lymphatic vessel density in polyp tissue associated with the need for revision CRS-surgery. As a conclusion, low density of lymphatic vessels distinguished patients with CRSwNP not only in the hotspot area of polyp tissue, but also in maxillary sinus mucosa. Yet, higher lymphatic vessel density seems to associate with polyp recurrence. Further studies are still needed to explore if formation of nasal polyps could be diminished by intranasal therapeutics affecting lymphangiogenesis.

Nasal sprays available for the treatment of cold and allergy symptoms currently use identical formulations and devices for adults as well as for children. Due to the obvious differences between the nasal airway dimensions of a child and those of an adult, the performance of nasal sprays in children was evaluated. Deposition patterns of nasal sprays administered to children were tested using a nasal cast based on MRI images obtained from a 12 year old child's nasal cavity. Test formulations emitting a range of spray patterns were investigated by actuating the device into the pediatric nasal cast under controlled conditions. The results showed that the nasal sprays impacted in the anterior region of the 12 year old child's nasal cavity, and only limited spray entered the turbinate region - the effect site for most topical drugs and the primary absorptive region for systemically absorbed drugs. Differences in deposition patterns following the administration of nasal sprays to adults and children may lead to differences in efficacy between these populations. Greater anterior deposition in children may result in decreased effectiveness, greater anterior dosage form loss, and the increased potential for patient non-compliance.

The human nasal microbiota and Staphylococcus aureus carriage.

Full Text Available BACKGROUND: Colonization of humans with Staphylococcus aureus is a critical prerequisite of subsequent clinical infection of the skin, blood, lung, heart and other deep tissues. S. aureus persistently or intermittently colonizes the nares of approximately 50% of healthy adults, whereas approximately 50% of the general population is rarely or never colonized by this pathogen. Because microbial consortia within the nasal cavity may be an important determinant of S. aureus colonization we determined the composition and dynamics of the nasal microbiota and correlated specific microorganisms with S. aureus colonization. METHODOLOGY/PRINCIPAL FINDINGS: Nasal specimens were collected longitudinally from five healthy adults and a cross-section of hospitalized patients (26 S. aureus carriers and 16 non-carriers. Culture-independent analysis of 16S rRNA sequences revealed that the nasal microbiota of healthy subjects consists primarily of members of the phylum Actinobacteria (e.g., Propionibacterium spp. and Corynebacterium spp., with proportionally less representation of other phyla, including Firmicutes (e.g., Staphylococcus spp. and Proteobacteria (e.g. Enterobacter spp. In contrast, inpatient nasal microbiotas were enriched in S. aureus or Staphylococcus epidermidis and diminished in several actinobacterial groups, most notably Propionibacterium acnes. Moreover, within the inpatient population S. aureus colonization was negatively correlated with the abundances of several microbial groups, including S. epidermidis (p = 0.004. CONCLUSIONS/SIGNIFICANCE: The nares environment is colonized by a temporally stable microbiota that is distinct from other regions of the integument. Negative association between S. aureus, S. epidermidis, and other groups suggests microbial competition during colonization of the nares, a finding that could be exploited to limit S. aureus colonization.

Full Text Available Usher syndrome type I (USH1 is an autosomal recessive disorder characterized by congenital profound deafness, vestibular areflexia and prepubertal retinitis pigmentosa. The first purpose of this study was to determine the pathologic nature of eighteen USH1 putative splicing variants found in our series and their effect in the splicing process by minigene assays. These variants were selected according to bioinformatic analysis. The second aim was to analyze the USH1 transcripts, obtained from nasal epithelial cells samples of our patients, in order to corroborate the observed effect of mutations by minigenes in patient's tissues. The last objective was to evaluate the nasal ciliary beat frequency in patients with USH1 and compare it with control subjects. In silico analysis were performed using four bioinformatic programs: NNSplice, Human Splicing Finder, NetGene2 and Spliceview. Afterward, minigenes based on the pSPL3 vector were used to investigate the implication of selected changes in the mRNA processing. To observe the effect of mutations in the patient's tissues, RNA was extracted from nasal epithelial cells and RT-PCR analyses were performed. Four MYO7A (c.470G>A, c.1342_1343delAG, c.5856G>A and c.3652G>A, three CDH23 (c.2289+1G>A, c.6049G>A and c.8722+1delG and one PCDH15 (c.3717+2dupTT variants were observed to affect the splicing process by minigene assays and/or transcripts analysis obtained from nasal cells. Based on our results, minigenes are a good approach to determine the implication of identified variants in the mRNA processing, and the analysis of RNA obtained from nasal epithelial cells is an alternative method to discriminate neutral Usher variants from those with a pathogenic effect on the splicing process. In addition, we could observe that the nasal ciliated epithelium of USH1 patients shows a lower ciliary beat frequency than control subjects.
