    The Schneider membrane is the mucosa that covers the inner part of the maxillary sinus cavities. The free surface is a ciliated pseudostratified epithelium, while the deeper portion is a highly vascularized connective tissue. The stromal fraction, bordering the bony wall of the sinus, after tooth loss can exhibit increased osteoclastic activity resulting in resorption of the bone in the posterior maxilla. Goal of our study was to isolate and characterize mesenchymal progenitors in the Schneider's membrane connective net and to evaluate their self ability to differentiate toward osteoblastic lineage, in absence of osteoinductive factors and osteoconductive biomaterials of support. This should indicate that maxillary sinus membrane represents an useful an approachable source of MSCs for bone tissue engineering and cell therapy and owns the intrinsic capacity to restore maxillary bone after tooth loss without the needing of biomaterials.

    Full Text Available Pensando em melhorar a qualidade de vida dos pacientes com doenças do humor vítreo, os oftalmologistas começaram a utilizar recentemente implantes biodegradáveis com corticoide. Estes mesmos implantes podem ser uma alternativa no tratamento da RSC e, para isso, realizamos um estudo experimental em seios maxilares de coelhos. OBJETIVO: Avaliar histologicamente a mucosa de seio maxilar de coelhos após a colocação de implante biodegradável de prednisolona. MÉTODO: Dezoito coelhos foram divididos aleatoriamente em dois grupos: Grupo 1: no seio maxilar esquerdo foi inserido um implante biodegradável com prednisolona; Grupo 2: No seio maxilar esquerdo foi inserido um implante biodegradável sem medicação. Os seios maxilares do lado direito serviram como controle. Após 7, 14 e 28 dias foram escolhidos aleatoriamente três coelhos de cada grupo e a resposta tecidual inflamatória foi avaliada. RESULTADOS: Foi encontrada diferença não significativa de inflamação na mucosa, quando comparamos o grupo de coelhos que receberam implantes com e sem medicação com o grupo controle; ou quando comparamos o grupo que recebeu implante com prednisolona com o grupo que recebeu implante sem medicação. CONCLUSÃO: Não foram observados sinais de toxicidade ou inflamação na mucosa do seio maxilar do coelho à presença do implante com ou sem prednisolona.In an attempt to improve the quality of life of patients with vitreous humor disease, ophthalmologists began offering steroid-eluting biodegradable implants to their patients. These implants can be used as an alternative treatment for CRS and this is why this experimental study was carried out on rabbit maxillary sinuses. OBJECTIVE: This study aims to assess the histology of the mucosa of the maxillary sinuses of rabbits after the placement of a prednisolone-eluting biodegradable implant. METHOD: Eighteen rabbits were randomly divided into two groups: group 1 - subjects had drug-eluting implants placed on their left maxillary sinuses; group 2 - subjects had non-drug-eluting implants placed on their left maxillary sinuses. The right maxillary sinuses served as the controls. After seven, 14, and 28 days three rabbits in each group were randomly picked to have their tissue inflammatory response assessed. RESULTS: Levels of mucosal inflammation were not significantly different between the groups with and without drug-eluting implants and the control group, or when the groups with drug-eluting implants and non-drug-eluting implants were compared. CONCLUSION: Signs of toxicity or mucosal inflammation were not observed in the maxillary sinuses of rabbits given prednisolone-eluting implants or non-drug-eluting implants.

    The aim of this study was to determine histologic findings in the maxilaarysinus mucosa by scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and ciliary activity within the nasal cavity by measuring the speed of mucociliary transport and after endoscopic sinus surgery (ESS). Thirty patients were enrolled. Thirty-eight antral mucosae of 24 24 patients were investigated according to ultrastructural changes and 6 patients were accepted as controls. At the 12th week, 12 antral nasal mucosae specimens of 8 patients were evaluated. All the specimens were taken from the medial rear wall of the antrum. The specimens were observed under a SEM and TEM. The mucociliary activity was measured within the nasal cavity by a saccharin test in all patients before the operation and after 12 weeks. Twenty people served as controls. In the specimens of the preoperative mucosa, the ciliated epithelium was heavily deciliated, interdigitation of the cell was loosened. In the samples taken 12 weeks after the operation, the ciliated cells were irregularly seen, the number of goblet cells was about the same as in the preoperative group and in the control, the number of the gland openings was higher than in the preoperative group and in the control. Also the interdigitation of the cells was enhanced. The histological and morphological features of the mucosa had improved. The period of the preoperative saccharin test was 12.15 minutes, whereas the period of the postoperative test was 9.08 minutes. The improvement was significant but both results were also significantly longer compared to the controls. These observations suggest that the histological, morphological and mucocilliary activity of the mucosa have not yet improved completely, it takes more than 12 weeks to recover, and the patients should be closely monitored in the postoperative months.

    Schwannoma, also known as neurilemmoma, is a solitary, encapsulated peripheral tumour of neuroectodermal derivation that originates from schwann cells of neural sheath of motor/ sensory peripheral nerves or sympathetic nerves. About one- third of all schwannomas occur in head and neck region but nose and paranasal sinuses, are rare sites. We report a case of schwannoma arising from the maxillary sinus and eroding the orbital floor. To the best of our knowledge, this is the sixth; case of schw...

  5. Pathologic changes in the maxillary sinus wall after conservative therapy in odontogenic maxillary sinusitis. Examination using bone scintigraphy

    International Nuclear Information System (INIS)

    Single photon emission computed tomographic bone scintigraphy (bone SPECT) was performed in 16 patients with odontogenic maxillary sinusitis to compare inflammatory changes in the maxillary sinus wall including the alveolar process (bony lesions) before and after conservative therapy. Morphologic changes in bony lesions as evaluated by bone SPECT images correlated with those of the maxillary sinus mucosa (mucosal lesions) as evaluated by CT images. Morphologic changes in the bony lesions also correlated with changes in inflammatory activity in the maxillary alveolar process as functionally evaluated by bone SPECT before and after conservative therapy. Odontogenic maxillary sinusitis is considered a disease in which maxillary alveolitis causes mucosal lesions as well as bony lesions. Changes in alveolitis are associated with morphologic changes in bony lesions after conservative therapy, and these changes affect the pathophysiologic nature of odontogenic maxillary sinusitis. Bone SPECT is valuable for predicting outcome and treatment planning in patients with odontogenic maxillary sinusitis. (author)

    Full Text Available Introduction: The pneumocele is a pathological expansion of paranasal sinus containing only air, which can move the nearby structures. Radiologically is a hiperneumatizacion and elongation of paranasal sinus, that can be associated with bone loss. Description: Patient with facial fullness and pains on right side, occasionally nasal blockage that worsen with pressure changes, at exploration presents protrusion of maxillary mucosa into the nostril. Discussion: Pneumoceles can occur in any paranasal sinus. Usually remain asymptomatic and they are not diagnosed until it takes place an external deformity or displacement of neighbouring structures to the sinus, causing symptoms. Conclusion: The maxillary sinus neumoceles are a rare differential diagnosis of mucocele, tumors and trigeminal neuralgia. Surgery is curative, preferring an endoscopic approach.

  7. Maxillary sinus carcinoma

    International Nuclear Information System (INIS)

    Primary site control, anatomical site of failure, survival, and complications of treatment were determined in a retrospective review of primary maxillary sinus carcinoma. Sixty-one patients were treated by radiation followed by surgery and 35 by radiation alone. Primary tumor control was achieved in 69% of patients receiving combined treatment, 14% of patients treated with radiation alone, and 49% of all patients. Local control did not differ with histological type. Virtually all epidermoid and undifferentiated carcinoma recurrences occurred within 2 years, but 27% of adenocarcinomas recurred after 2 years

  9. Maxillary Sinus mucormycosis mimicking sinus malignancy

    International Nuclear Information System (INIS)

    Mucormycosis is an opportunistic fulminant fungal infection in diabetic and immunocompromised patients. The infection is acquired in the nose and paranasal sinuses by the inhalation of the fungal spores. We report of a case of maxillary sinus mucormycosis in a 32-years-old non diabetic woman. She had right side facial pain, headache, unilateral right side nasal obstruction, and post nasal discharge (PND) for five years. Nasal endoscopy revealed pus and granulation tissue, and semi-black middle turbinate in right side nasal cavity. Computed tomography showed bone erosion and a large soft tissue mass similar to sinus carcinoma in maxillary sinus with extension into the ethmoidal sinus. She underwent functional Endoscopic sinus surgery. Macroscopically, the specimen consisted of multiple tissue fragment 0.8-1 cm. Microscopic findings included an inflammatory cells and deposited fungal elements (mucormycosis). So in the paranasal sinus and nasal cavity mass, mucormycosis should be included in the differential diagnosis, especially in the non diabetic and young patients. (author)

  10. Roentgen diagnosis of the mucosal cyst in the maxillary sinus

    International Nuclear Information System (INIS)

    The most common cystic lesion of the maxillary sinuses is the mucosal cyst. In reviewing a 5-years material of 5026 pathological X-ray examinations of the sinuses 12.2% of these were found to have mucosal cysts. These cysts usually do not give rise to symptoms and require no treatment, but are often misdiagnosticated as polyps, compact maxillary sinuses, hypertrophy of the lining mucosa or tumors. As radiologic examination of the sinuses is a common procedure and the diagnosis of a mucosal cyst is possible other diagnoses may not be given in most cases. (orig.)

    To facilitate safe placement of orthodontic anchor screws (miniscrews), we investigated the frequency of maxillary sinus perforation after screw placement and the effect of sinus perforation on screw stability. Maxillary sinus perforations involving 82 miniscrews (diameter, 1.6 mm; length, 8 mm) were evaluated using cone-beam computed tomography. All miniscrews were placed in maxillary alveolar bone between the second premolar and first molar for anchorage for anterior retraction in patients undergoing first premolar extraction. The placement torque and screw mobility of each implant were determined using a torque tester and a Periotest device, and variability in these values in relation to sinus perforation was evaluated. Eight of the 82 miniscrews perforated the maxillary sinus. There was no case of sinusitis in patients with miniscrew perforation and no significant difference in screw mobility or placement torque between perforating and non-perforating miniscrews. The sinus floor was significantly thinner in perforated cases than in non-perforated cases. A sinus floor thickness of 6.0 mm or more is recommended in order to avoid miniscrew perforation of the maxillary sinus. PMID:26062857

  16. Development of maxillary sinuses in childhood

    International Nuclear Information System (INIS)

    The purpose of this study was to clarify the development of the maxillary sinuses in childhood. Between June 1983 and December 1985, a total of 120 children under 15 years old were enrolled in this study. Cranial X-ray CT scans were performed using a GE CT/T 8800 and slice thickness were 1.5 mm under 2 years old and 5.0 mm for age above 3 years. Forty-five patients who had facial anomalies, or growth retardation, or premature infants were excluded from further analysis. The remaining 75 patients were evaluated for the development of the maxillary sinuses. The scans were made in the coronal and saggital planes. Anterior-posterior diameter (length) and mid-lateral diameter (width), and volume of the maxillary sinuses were measured by using the image processing system that was developed by us. Cranio-caudal diameter (height) was calculated by multiplying the slice thickness by the total number of the slices taken from the area of the maxillary sinus. Three dimensional structures of the maxillary sinuses were also displayed using the same system. The sizes of maxillary sinuses in the new born were 7.3 ± 1.9 mm(mean ± S.D.) in length, 6.7 ± 1.6 mmin height, and 5.2 ± 1.3 mm in width. These results were similar to those reported by others. The sizes of the maxillary sinuses were increased rapidly by the age 3 - 4 years. The numerical values for theses three measurements were greater than those previously reported, especially for height. The levels of upper borders of these maxillary sinuses in infants and young children were higher than those of inferior rimbs of the orbits. The results for the three dimensional displays and volume measurements performed on 66 children above 1 year old are also presented. (author)

    The authors evaluated the health of the maxillary sinus in a group of 18 patients who had undergone sinus lift surgery for implantation purposes, using computed tomography and endoscopic imaging as a means of diagnosis. The study was performed after a mean interval of 31 months. All sinus lift operations were carried out using the lateral flap technique. The authors evaluated graft characteristics and intraoperative and postoperative complications and compared the results with computed tomography and endoscopic images. Endoscopy of a maxillary sinus that underwent microlaceration of the mucosa during sinus lifting showed a situation compatible with healthy conditions. In cases complicated by macrolaceration, the endoscopic picture was typical of sinusitis, even where clinical conditions of this type were not present. In the absence of intraoperative complications, the endoscopic appearance of sinus mucosa appears to improve when autologous graft material is used. PMID:11794569

    Full Text Available The standard treatment in the early stage of maxillary sinus cancer is surgical resection followed by postoperative radiation therapy. However, for locally advanced maxillary sinus cancer, a multimodality treatment approach is strongly recommended to improve the survival rate and quality of life of the patient. We determined the treatment outcomes of induction chemotherapy, concurrent chemoradiation therapy, and surgical resection for locally advanced maxillary sinus cancer. Forty-four patients with locally advanced maxillary sinus cancer, who had been treated between January 1990 and April 2008 at Kangnam St. Mary's Hospital, were retrospectively analyzed. The objective response rates were 70%, 53%, and 57% in the intra-arterial induction chemotherapy, intravenous induction chemotherapy, and concurrent chemoradiation therapy groups, respectively. The orbital preservation rates were 83%, 100%, and 75% in the intra-arterial induction chemotherapy, intravenous induction chemotherapy, and surgical resection groups, respectively. In seven of nine patients in whom the orbit could be preserved after induction chemotherapy, the primary tumors were removed completely. However, although the orbits were preserved in three patients who underwent surgical resection as a primary treatment, all three cases were confirmed to be incomplete resections. We found that active induction chemotherapy for locally advanced cancer of the maxillary sinus increased the possibility of complete resection with orbital preservation as well as tumor down-staging.

  19. Carcinoma of the maxillary sinus

    International Nuclear Information System (INIS)

    A retrospective review of 124 patients of carcinoma of the maxillary sinus treated at Kurume University Hospital from 1971 to 1980 was completed. Of these 124 patients, 111 patients had not been previously treated and underwent curative treatment, 8 patients underwent palliative treatment, and 5 patients were those who had been previously treated at other clinics. The results of this retrospective studies are summarized as follows: 1) In the 58 patients who were followed up for 5 years or more after the onset of initial curative treatment, the 3- and 5-year crude survival rates calculated by direct method were 58.6% and 51.7%, respectively. 2) In the 111 patients who underwent curative treatments, the 3- and 5-year cumulative survival rates calculated by the actuarial method were 61.8% and 52.3%, respectively. 3) Among various factors which can be determined before the treatment, T category and L.V. histological classification were considered to be useful in order to estimate the prognosis. 4) With respect to T categorization, the JJC proposal proved to be better than the AJC proposal. 5) The majority of causes of deaths was uncontrolled primary lesion. Involvement of the cervical lymph nodes were controlled in most cases and distant metastasis were not frequent. 6) As for the treatments, the best modalities appeared to be the following two combinations: (1) infusion, radiation and necrotomy followed by an eradicating surgery and (2) infusion, radiation and necrotomy associated with a mass reduction surgery. 7) Three year crude survival rate calculated by direct method was equally 80.0% in the above two combination therapies. Final conclusions on the comparison between these two Combination treatments await further follow-up studies of more patients. (author)

    2004-04-01

    Odontogenic sinusitis is a well-recognized condition and accounts for approximately 10% to 12% of cases of maxillary sinusitis. An odontogenic source should be considered in patients with symptoms of maxillary sinusitis who give a history positive for odontogenic infection or dentoalveolar surgery or who are resistant to standard sinusitis therapy. Diagnosis usually requires a thorough dental and clinical evaluation with appropriate radiographs. Common causes of odontogenic sinusitis include dental abscesses and periodontal disease perforating the Schneidarian membrane, sinus perforations during tooth extraction, or irritation and secondary infection caused by intra-antral foreign bodies. The typical odontogenic infection is now considered to be a mixed aerobic-anaerobic infection, with the latter outnumbering the aerobic species involved. Most common organisms include anaerobic streptococci, Bacteroides, Proteus, and Coliform bacilli. Typical treatment of atraumatic odontogenic sinusitis is a 3- to 4- week trial of antibiotic therapy with adequate oral and sinus flora coverage. When indicated, surgical removal of the offending odontogenic foreign body (primary or delayed) or treatment of the odontogenic pathologic conditions combined with medical therapy is usually sufficient to cause resolution of symptoms. If an oroantral communication is suspected, prompt surgical management is recommended to reduce the likelihood of causing chronic sinus disease. PMID:15064067

The lateral lamella of the affected turbinate was removed and the inspissated material was drained. Histopathologic e...

  2. Volumetric measurement of the maxillary sinus by coronal CT scan

    International Nuclear Information System (INIS)

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

  4. Prognostic factors of maxillary sinus epithelial carcinoma

    International Nuclear Information System (INIS)

    Objective: To evaluate the relation between clinicopathological character- isties and prognosis in maxillary sinus epithelial carcinoma (ECMS). Methods: 124 such patients were reviewed retrospectively. There were treated by radiotherapy alone (RT-, 40 patients), surgery alone(S-, 18 patients)and combined modality therapy (R+ S-, 66 patients). Kaplan-Meier method was used to analyze the survival, Logrank test was used to compared the difference between groups. Multivariate analysis was performed by Cox proportional hazard model. Results: The overall 5-year survival, cancer-specific survival and progression-free survival rates were 32.5%, 37.4% and 27.2%, respectively. Univariate analysis showed that tumor location, histological type, T stage, N stage, clinical stage and treatment modality were associated with cancer-specific survival and progression-free sur- vival, while age was only associated with cancer-specific survival. Multivariate analysis indicated that histological type, T stage, clinical stage and treatment modality were independent prognostic factors. Conclusions: T stage and clinical stage are the independent prognostic factors for maxillary sinus epithelial carcinoma. Prophylactic neck irradiation is necessary even for T3-T4N0 patients. The best treatment strategy for maxillary sinus carcinoma needs further research. (authors)

  5. Primary malignant lymphoma of the maxillary sinus: CT and MRI

    International Nuclear Information System (INIS)

    We reviewed the CT and MRI of seven patients with primary malignant lymphoma of the maxillary sinus to find if there are characteristic imaging findings suggestive of the disease. The images were analysed for appearance, size, signal, internal characteristics, extent of tumour, bone change and lymph node enlargement. In two patients, the tumour first presented with mucosal thickening. In the remaining five, the tumours were an expansile mass 4-6 cm in diameter at the time of detection. Although it was difficult to distinguish tumour from mucosa or obstructed fluid on CT, T2-weighted MRI enabled us to separate tumour from normal mucosa or fluid. In two patients, the tumours were heterogeneous. Calcification and haemorrhage were observed in one patient. Periantral soft-tissue infiltration was always present, even when tumour appeared as slight mucosal thickening. Posterior extension was seen in all patients. Permeative and lytic bone destruction accompanied most cases of periantral soft-tissue infiltration; mixed destruction and sclerosis was also observed. Mucosal thickening with periantral soft-tissue infiltration may suggest malignant lymphoma of the maxillary sinus in its early form. Various types of bone change may accompany the periantral soft-tissue infiltration. (orig.)

  6. Radiological diagnosis of maxillary sinus aspergillosis

    International Nuclear Information System (INIS)

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

  7. Pneumatisation of the maxillary sinus in normal and symptomatic children

    International Nuclear Information System (INIS)

    The pattern of pneumatisation and normal width of the maxillary sinus in 191 Nigerian infants and children whose age range was 6 months to 14 years was determined. Fifty-four percent of children with no respiratory tract or sinus infection had opaque maxillary sinus. A figure of 44.5% was obtained amongst children with suspected bronchopneumonia. Only 41.5% of suspected cases of sinusitis, acute and chronic middle ear disease had opaque sinus. The highest rate of sinus opacity was seen in children under 2 years who were asymptomatic. The mean maximal width of normally aerated sinus was 8.74 mm for children under 2 years, 16.5 mm for 3-6 years, 21.5 mm for 7-11 years and 25 mm for children 12 years and above. We conclude that maxillary sinus opacity in our experience is an unreliable index for the diagnosis of sinusitis in children. (orig.)

    The purpose of this study was to examine the inferior expansion of the maxillary sinus floor following maxillary molar extraction. Cone beam computed tomographic images of 59 subjects were used to evaluate the height difference of the maxillary sinus floor between extraction sites and contralateral dentate sites. The height of the maxillary sinus floor was defined as the vertical distance to the Frankfort plane from the level of the anterior nasal spine to the most inferior point of the sinus floor. We examined the difference in sinus pneumatization according to the number of missing teeth and the vertical relationship of the molar roots to the sinus floor. The inferior expansion of the maxillary sinus floor was 1.20 {+-} 1.86 mm on the maxillary first molar and 1.90 {+-} 2.42 mm on the maxillary second molar. Increased expansion was observed in cases where two proximate molars were extracted. There was no significant difference in sinus pneumatization following extraction according to the vertical relationship of the molar roots to the sinus floor. The results of this study confirm that sinus pneumatization occurs following maxillary molar extraction. In situations where pneumatization can affect treatment after molar extraction, three-dimensional radiography should be considered.

    Aspergilloma of the paranasal sinus is a non-invasive form of aspergillosis, most often in the maxillary sinus. This case presents an 86-year-old female with aspergilloma of the left maxillary sinus. The patient's chief complaint was intermittent pain on the left maxillary first premolar area. A radiopacification of the left maxillary sinus was observed on the panoramic radiograph. Cone-beam computed tomography revealed complete radiopacification of the left maxillary sinus and scattered multiple radiopaque mass inside the lesion. Biopsy was performed under local anesthesia. On microscopic examination, numerous fungal hyphae, which branch at acute angle, were observed. The diagnosis was made as an aspergilloma based on the histopathologic examination.

    Full Text Available Malignant tumors of the paranasal sinus are uncommon, constituting less than 1% of all malignancies and 3% of all head and neck cancers. Nonsquamous cancers of the maxillary sinus are even rarer as is evident from the limited data available on the clinical characteristics and outcomes. Mucoepidermoid carcinoma accounts for 13% of all malignancies occurring in maxillary sinus. We report a rare case of high-grade mucoepidermoid carcinoma of maxillary sinus in a 45-year-old female along with review of the literature.

  11. Maxillary sinusitis - a comparative study of different imaging diagnosis methods

    International Nuclear Information System (INIS)

    We conducted prospective study comparing different methods (plain X-rays, computed tomography and ultrasonography mode-A) for the initial diagnosis of maxillary sinusitis. Twenty patients (40 maxillary sinuses) with a clinical history suggestive of sinusitis included in this study. The results were classified as abnormal or normal, using computed tomography as gold standard. The sensitivity for ultrasonography and plain X-rays was 84.6% and 69.2%, respectively. The specificity of both methods was 92.6%. This study suggests that ultrasonography can be used as a good follow-up method for patients with maxillary. sinusitis. (author)

  13. A clinical analysis of maxillary sinus cancer

    International Nuclear Information System (INIS)

    Thirty-two patients (23 males, 9 females) with maxillary sinus cancer were treated at Kyushu University Hospital during 2000-2008. They were classified by T classification as 5 cases with T2, 13 with T3, 12 with T4a, and 2 with T4b. Between 2000 and 2003, 16 patients were given irradiation, intra-arterial 5-fluorouracil (5-FU) infusion chemotherapy, maxillectomy and postoperative irradiation. After 2004, two patients with T4b maxillary sinus cancer were treated by superselective intra-arterial chemotherapy with Cisplatin (CDDP) and Docetaxel (DOC) and irradiation. Other patients were given irradiation and chemotherapy with S-1 and intra-arterial infusion of 5-FU. The 3-year survival rate was 68.3% for all patients. The 3-year survival rate was 74.6% for patients treated after 2004, whereas it was 62.5% for patients treated between 2000 and 2003. Chemotherapy with S-1 or superselective intra-arterial chemotherapy with CDDP and DOC improved cause-specific survival rates. (author)

  14. Maxillary sinus carcinoma: result of radiation therapy

    International Nuclear Information System (INIS)

    This hundred and sixteen patients with carcinoma of the maxillary sinus received primary therapy consisting of external beam irradiation alone or in combination with surgery and/or chemotherapy at the Department of Radiology, Tokyo Medical and Dental University Hospital, between 1953 and 1982. In our institution, methods of treating cancer of the maxillary sinus have been changed from time to time and showed different control rates and clinical courses. An actuarial 10-year survival rate of 21% has been obtained by the megavoltage irradiation alone as well as 34% actuarial 10-year survival rate by megavoltage irradiation with surgery. After the introduction of conservative surgery followed by conventional trimodal combination therapy, the local control rate has been improved. The amount of functional, cosmetic, and brain damages have been remarkably decreased by this mode of therapy. The actuarial five year survival rate was 67%. In addition, along with the improvement of the local control rate, the control of nodal and distant organ metastases have been emerging as one of the important contributions to the prognosis of this disease

    In everyday examination, it is usual to encounter odontogenic maxillary sinusitis patients. Odontogenic maxillary sinusitis is generally best diagnosed by dental X-ray imaging. Many medical facilities not having a dental X-ray unit use coronal computed tomography (CT) images to diagnose odontogenic maxillary sinusitis. Coronal CT imaging causes artifacts, however due to dental prosthesises. Computed tomography-Multiplanar reformation (CT-MPR) imaging has proved useful in evaluating the paranasal sinus because it is not influenced by dental prosthesises. We evaluated the usefulness of CT-MPR for diagnosing odontogenic maxillary sinusitis by retrospectively analyzing 16 patients, with the following results. We couldn't diagnose all cases of odontogenic maxillary sinusitis in posteroanterior and Waters projection images. Panoramic radiography is needed to diagnose odontogenic maxillary sinusitis. Dental X-ray imaging missed some cases, but all cases were diagnosed by CT-MPR imaging, giving a 100% diagnosestic rate. CT-MPR imaging is thus at least as valuable or better than dental X-ray imaging in diagnosing odontogenic maxillary sinusitis. (author)

  18. Radiation Therapy of Maxillary Sinus Cancer

    International Nuclear Information System (INIS)

    Purpose: Maxillary sinus cancers usually are locally advanced and involve the structures around sinus. It is uncommon for this cancer to spread to the regional lymphnodes. For this reason, local control is of paramount important for cure. A policy of combined treatment is generally accepted as the most effective means of enhancing cure rates. This paper reports our experience of a retrospective study of 31 patients treated with radiation therapy alone and combination therapy of surgery and radiation. Materials and Methods: Between July 1974 and January 1992, 47 patients with maxillary sinus cancers underwent either radiation therapy alone or combination therapy of surgery and radiation. Of these, only 31 patients were eligible for analysis. The distribution of clinical stage by the AJCC system was 26%(8/31) for T2 and 74%(23/31) for T3 and T4. Eight patients had palpable lymphadenopathy at diagnosis. Primary site was treated by Cobalt-60 radiation therapy using through a 45 .deg. wedge-pair technique. Elective neck irradiation was not routinely given. Of these 8 patients, the six who had clinically involved nodes were treated with definite radiation therapy. The other two patients had received radical neck dissection. The twenty-two patients were treated with radiation alone and 9 patients were treated with combination radiation therapy. The RT alone patients with RT dose less than 60 Gy were 9 and those above 60 Gy were 13. Results: The overall 5 year survival rate was 23.8%. The 5 year survival rate by T-stage was 60.5% and 7.9% for T2 and T3, 4 respectively. Statistical significance was found by T-stage (p30.1). The 5 year survival rate for RT alone and combination RT was 22.5% and 27.4%, respectively. The primary local control rate was 65%(20/31). Conclusion: This study did not show significant difference in survival between RT alone and combination RT. There is still much controversy with regard to which treatment is optimum. Improved RT technique and development of multimodality treatment are essential to improve the local control and the survival rate in patients with advanced maxillary sinus cancer

  19. Measurement of maxillary sinus volume using Computed Tomography

    International Nuclear Information System (INIS)

    To propose a standard value for the maxillary sinus volume of a normal Korean adult by measuring the width and height of the sinus and analyzing their correlation and the difference of the sinus size respectively between sexes, and on the right and left sides. Fifty-two (95 maxillary sinuses) out of 20 years or over aged patients who had taken CT in the Department of Dental Radiology, Yonsei University, Dental Hospital, between February 1997 and July 1999 who were no specific symptom, prominent bony septa, pathosis, clinical asymmetry and history of surgery in the maxillary sinus were retrospectively analyzed. The mean transverse width, antero-posterior width, height and volume of the normal Korean adult's maxillary sinuses were 28.33 mm, 39.69 mm, 46.60 mm and 21.90 cm3, respectively. There was a significant sex difference in the sinus volume (p<0.05). In the mean antero-posterior width, height and volume of the sinus, no significant difference was observed between both sides. All four measurements showed a significant correlation between both sides (p<0.0001). The widths and height of the sinus all showed a significant correlation with the sinus volume (p<0.0001). In the Korean normal adult's maxillary sinus, males tended to be larger than females. Except for the transverse width, all of the measurements showed no significant difference between the right and left side, but significant correlations in the four measurements between both sides were observed. Thus, the overgrowth or undergrowth in the unilateral maxillary sinus may suggest a certain pathosis or developmental abnormalities in the maxillary sinus.

  20. CT findings of fungal infection of maxillary sinuses

    International Nuclear Information System (INIS)

    In recent years, fungal infection of the paranasal sinuses has increased. However, the preoperative diagnosis is often difficult. We report four cases of fungal infection of the paranasal sinuses. Their CT scans. Showed: 1) A high density area in the homogeneous shadow. 2) A mass suspected of being a fungus ball surrounding the opening of the maxillary sinus to the nasal cavity. 3) Thickening of bone in the maxillary sinus except in the inner wall. These results indicate that CT scanning is useful in the diagnosis of fungal infection of the paranasal sinuses. (author)

    In this manuscript, we present a rare case report of giant complex odontoma in the maxillary sinus, where the applied therapy included complete excision of the lesion with a conservative approach. Odontomas are also called benign growth abnormalities or hamartomas. They represent a more common type of odontogenic tumor and are related to various disorders such as bad dental placements, expansion, increased volumetric bone, and no eruption of permanent teeth. Usually they have an asymptomatic evolutionary course. The etiologic factors, although obscure, are related to local trauma, infection, and genetic factor. The structural composition of an odontoma consists of mature dental tissues. Odontomas can be differentiated according to their anatomical presentations: Compound odontoma-clusters of several denticles and complex odontoma-well defined tumefaction mass. The diagnosis can be performed by radiographic examination. PMID:26389051

    Context: Maxillary sinusitis is an important issue in dentistry and maxillofacial surgery. This study aims to present a systematic review of etiologies and treatments of odontogenic maxillary sinusitis. Evidence Acquisition: An electronic database search was performed based on related MeSH keywords. Articles published between January 2001 and December 2014 was selected according to the inclusion criteria. The information extracted from various studies was categorized in various tables. Results: The study selected 19 studies. In most studies, oroantral fistula (OAF) was the most common etiology of odontogenic sinusitis. Alpha-hemolytic streptococcus was the most common flora in sinusitis with dental origin. The literature shows that the Caldwell-Luc approach may be the best method for treating sinusitis in cases of displaced teeth. Conclusions: OAF is a common cause of odontogenic maxillary sinusitis and may easily be treated by endoscopy and fistula closure. Maxillofacial surgeons and dentists should consider this problem to avoid misdiagnosis and prevent complications. PMID:26756016

    The clinical course and pathologic features of a 72 year old female who presented with epistaxis are presented. Radiographic findings were notable for a large, soft tissue lesion filling the maxillary sinus with significant bony erosion and expansion. The patient was ultimately diagnosed with epithelioid hemangioendothelioma (EHE) and underwent endoscopic resection. She has no evidence of local, regional or distant recurrence 14 months post-surgery. The rarity of this neoplasm, the unusual anatomic location and non-specific symptoms present diagnostic and management challenges. Epithelioid vascular tumors encompass a spectrum of benign and malignant tumors. EHE itself is thought to have an intermediate malignant behavior pattern, though cases with indolent behavior have been reported. Differentiation of EHE from other lesions has historically based on histopathology. Additionally, recent studies have described a recurrent genetic fusion WWTR1-CAMTA1 in EHE, involving t(1;3) (p36;q25). This represents the second reported case of EHE arising in a paranasal sinus. The histopathologic findings of this lesion are reviewed. PMID:25963905

  5. Preoperative radiotherapy of maxillary sinus cancer

    International Nuclear Information System (INIS)

    This study was to evaluate the effectiveness of preoperative radiotherapy in maxillary sinus cancer. A retrospective analysis was done for 42 patients with maxillary sinus cancer who were treated with radiation with or without surgery from April 1986 to September 1996. There were 27 male and 15 female patients. Patients' age ranged from 24 to 75 years (median 56 years). Stage distribution showed 2 in T2, 19 in T3, and 21 in T4 lesions. The histologic type was squamous cell carcinoma in 38, undifferentiated carcinoma in 1, transitional cell carcinoma in 1, and adenoid cystic carcinoma in 2 patients, All patients were treated with radiation initially with a dosage range of 50.4-70.2 Gy (median 70.2 Gy) before further evaluation of remnant disease. Eleven patients were given induction chemotherapy (2 cycles of 5-fluorouracil and cisplatin) concurrently with radiotherapy. Six to eight weeks after radiotherapy with or without chemotherapy, computerized tomography (CT) of paranasal sinus was taken to evaluate remnant disease. If the CT finding showed remnant disease, a Caldwell-Luc procedure was done to get the specimen of suspicious lesions. A radical maxillectomy was done if the specimen was proven to contain malignancy. In contrast periodic follow-up examination was done without any radical surgery if the tissue showed only granulation tissue. Follow-up period ranged from 3 to 92 months with a median 16 months. Nine (21.4%) patients showed complete response (CR) and 33 patients (78.6%) showed persistent disease (PER) to initial radiotherapy. Among the 9 CR patients, 7 patients had no evidence of disease (NED), 1 patient had local failure, and 1 patient had regional failure. Among 33 PER patients, salvage total maxillectomy was done in 10 patients, and the surgery was not feasible or refused in 23 patients. Following the salvage radical surgery, 2 patients were NED and 8 patients were PER status. Overall and disease- free survival rate at 5 years was 23.1% and 16.7%, respectively. The only factors associated with the overall survival rate was the response to radiotherapy (p<0.01). The only factors associated with the overall survival rate was the response to radiotherapy. We could omit a radical mutilating surgery by preoperative irradiation in 7 of 42 patients (21.4%) so as to preserve their facial integrity

  7. Trimodal combination therapy for maxillary sinus carcinoma

    International Nuclear Information System (INIS)

    Purpose: This study was conducted to evaluate the effectiveness of trimodal combination therapy (radiotherapy, intra-arterial chemotherapy, antrotomy) for the treatment of primary maxillary sinus carcinoma. Methods and Materials: Between 1977 and 1996, 110 patients with maxillary squamous cell carcinoma were treated with trimodal combination therapy at Tokyo Medical and Dental University Hospital. All tumors were classified according to the 1997 UICC TNM staging system. Eighty percent of patients had T3 or T4 tumors. The T3 and T4 tumors were also classified into three groups according to their location, as visualized using computed tomography: the posterior-lateral (P) group, the medial (M) group, and the upper (U) group. Eight patients received additional radiotherapy, and 37 patients underwent a second surgical procedure, in addition to the trimodal combination therapy. Results: The 5-year cause-specific survival and local control rates were 71% and 65%, respectively. The 5-year local control rate was 80% for the T1+2 tumors, 64% for the T3 tumors, and 52% for the T4 tumors (p=0.06). Patients in the P+M group who received a 5-fluorouracil (5-FU) dosage of more than 3500 mg had a better 5-year local control rate than patients who received a 5-FU dosage of less than 3500 mg (p=0.01). No improvement in the local control rate after a second surgical procedure or additional irradiation treatment was observed in any of the groups. Conclusion: Trimodal combination therapy provides good local control, with the final outcome depending on the T stage of the tumor and the dosage of 5-FU

  8. Radiotherapy of malignant tumor of maxillary sinuses

    International Nuclear Information System (INIS)

    Sixty nine patients of malignant tumors of the maxillary sinuses were treated at the Yonsei Cancer Center from January 1970 to March 1978 by CO-60 teletherapy unit. We analyzed their clinical findings, histopathological findings, clinical staging, treatment and results. The results are as follows; 1. Male to female ratio was 3 : 1. The most prevalent age group was in fifth, sixth and seventh decades (82.6%). 2. Histologically, squamous cell carcinoma occurred most frequently which was 53 in 69 patients (76.8%). Lymphoma and adenoid cystic carcinoma were 3 patients (4.3%) respectively. 3. Maxillary swelling was most frequent clinical manifestation and can be seen in 50 out of 69 patients (72.5%). 4. Clinical staging according to TNM system proposed by Sisson can be done in 49 patients. Majority of patients were T-3 and T-4 and occupied 83.7% (41/49). According to Ohmgren's Line, tumor locating in infrastructure were 33 patients and in suprastructure 16 patients. 5. Among 69 patients, 59 patients were treated by radiation only, 5 patients were surgery plus radiation and 5 patients by chemotherapeutic infusion plus radiation. 6. In 31 patients who might be passed 5 years after treatment, follow up can be done in only 13 patients. 10 patients were treated by radiation only and 3 patients by surgery plus radiation. Presumed 5 year survival rate was 3/10 (30%) in patients with radiation only and 2/3 (66.7%) in patients with surgery plus radiation. Among 13 patients, 5 patients occurred infrastructure and 5 patients in suprastructure. Mean survival months of patient with infrastructure were 49 months and suprastructure were 31.8 months.

  9. Maxillary sinus carcinoma: Natural history and outcome

    International Nuclear Information System (INIS)

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

    The maxillary sinus is the largest paranasal sinuses. Foreign bodies of nosal sinus can caused by car accidents, firearm attacks, or iatrogeniccause. We reported two rare cases of foreign body of pulp needle and loach. The clinical manifestations might include facial numbness, facial paresthesia, swelling, nasal congestion, facial pain, eye discomfort, limited mouth opening and relapse and etc. Both CT scan and the medical history were helpful in diagnosis. Functional endoscopic surgery would be the first choice of treatment. PMID:26911073

    Herein, we report a case of drug-induced Stevens Johnson syndrome. (SJS). A 56-year old female visited our hospital complaining of right cheek pain. Local examination revealed that the right ostium of the maxillary sinus was open and that the maxillary sinus mucosa was invaded by tumor. Biopsy revealed a histopathological diagnosis of squamous cell carcinoma. We therefore diagnosed the patient as a case of maxillary sinus carcinoma (T3N0M0) based on the CT, MRI and FDG-PET findings. During chemoradiotherapy for maxillary sinus cancer, the patient developed oral mucosal inflammation of progressively worsening severity; we initially thought that the symptom was a side effect of the treatment; however, several days later, skin lesions appeared throughout the body. We consulted a dermatologist, who suspected SJS. The patient was initiated on high-dose steroid therapy (steroid pulse therapy), and the symptoms improved. Because of SJS is a fatal drug eruption, early diagnosis and prompt treatment are important. In patients receiving chemoradiotherapy showing severe oral mucosal inflammation outside the irradiation area or oral mucosal inflammation associated with skin lesions throughout the body, it is necessary to bear in mind the possibility of SJS.

    2013-01-01

    Full Text Available One undesirable sequela of root canal treatment is the overextension of endodontic material into the maxillary sinus, which may represent a risk factor for maxillary sinus aspergillosis (MSA. Diverse clinical presentations of aspergillosis have been reported and they vary depending on the immune status of the host. The noninvasive form called Aspergillus mycetoma occurs mostly in healthy people. This report describes a case of MSA associated with root canal over fi lling in a 27-year-old healthy man. The patient had been asymptomatic for 6 years after root canal treatment. Radiography revealed a diffuse radiopaque mass inside the left maxillary sinus, with radiolucent areas near the cortical bone of the maxillary sinus. Computed tomography (CT showed the presence of material with a density similar to that of soft tissue. Imaging fi ndings suggested that the calci fi cation fi lled the left maxillary antrum, without expansion or bone destruction. The lesion was removed, and microscopic examination of the specimen revealed an in fl ammatory process with numerous dichotomized fungal structures (compatible with Aspergillus sp.. Histopathological features were compatible with aspergillosis. Treatment consisted of surgery and adjunctive anti-fungal therapy with itraconazole. Clinical and radiographic follow-up revealed no recurrence of the lesion.

    To investigate and compare the prevalence, size, and location of maxillary sinus septa on panoramic and cone beam computed tomography (CBCT) images.Two hundred patients who had taken both panoramic and CBCT images were included. The location of maxillary sinus septa on the panoramic radiographs were recorded and confirmed on the CBCT images. Also the size of septa was measured on the reformatted CBCT images. The prevalence of the patients who had maxillary sinus septa was 51.0% and they showed 179 septa totally. Among them 51.0% of the patients had one septum, 32.4% two septa, 13.7% three, and 2.9% four. The measured heights of the septa were 4.37 {+-} 2.87 mm, 3.51 {+-} 2.47 mm, and 3.04 {+-} 2.37 mm in the medial, middle, and lateral areas, respectively. It was revealed that 1.0% was located at canine region, 18.0% at first premolar, 25.0% at second premolar, 22.7% at first molar, 19.8% at second molar, and 14.0% at third molar region. Among 213 septa depicted by the panoramic radiographs, only 69.0% were confirmed at the CBCT images. Since various heights and courses of the septa can develop in all parts of the maxillary sinus, adequate assessment of the inner aspect of the maxillary sinus is essential to avoid complications during sinus augmentation procedures. CBCT scanning is the preferred radiographic method for detecting the presence of sinus septa.

  5. CT features in second cancers of the maxillary sinus

    International Nuclear Information System (INIS)

    Five patients with a second maxillary cancer (squamous cell carcinoma), which developed 6 to 17 years after initial treatment for the first cancer on the opposite side, were compared with 21 control cases with a primary cancer on the basis of computed tomography (CT) findings. Generally, the second cancer was found at an earlier stage. The specific CT findings of early sinus carcinoma were uneven soft tissue distribution in the antrum and tumor permeation with bone fragments remaining at the original tumor site. These findings may be helpful for distiguishing this cancer from benign chronic sinusitis and/or other malignant sinus disease. The pterygoid process, medial bony wall, and ethmoid sinus had a tendency to be spared in most of the 5 patients with second maxillary cancer compared to the 21 control cases. (orig.)

    Efficacy of prescribed noninvasive & invasive types of treatment of maxillary sinusitis has been compared with low-dose LASER therapy (LLT). After going through the observations of different authors on the therapeutic role of LLT (GaA1AS-LASER) in non-ENT infective diseases, its use in ‘sinusitis’ has been adjudged. Such type of study-report has not been found by us in the literatures, available to us.

  7. Treatment results of maxillary sinus carcinoma

    International Nuclear Information System (INIS)

    From 1967 through 1983, a total of 617 patients with maxillary sinus carcinoma were treated with radiation therapy. An overall actuarial 5-year survival rate was 36.2%. According to chronological groups, it was 24.1% in 217 patients treated during the period 1967-1971, 40.0% in 155 patients during the period 1972-1975, and 44.6% in 245 patients during the period 1976-1983. According to T staging, an actuarial 5-year local control rate was 60.0% for T1 (9 patients), 43.1% for T2 (181), 31.7% for T3 (246), and 19.2% for T4 (181). According to initial treatment, the patients were divided into four groups -- Group A treated with radiation therapy (RT) alone, Group B with RT combined with intra-arterial infusion of 5-fluorouracil (RT+5-FU), Group C with RT combined with surgical removal through curettage (RT+OP), and Group D with multidisciplinary treatment consisting of RT, 5-FU regional infusion, and curettage (RT+5-FU+OP). For T2, the 5-year actuarial local control rate was 25.5% in Group A (51 patients), 45.0% in Group B (55), 58.2% in Group C (23), and 51.5% in Group D (52). The corresponding figures for T3 were 13.2% in Group A (85 patietns), 33.6% in Group B (78), 52.3% in Group C (31), and 45.9% in Group D (52); and those for T4 were 7.6% in Group A (77 patients), 27.2% in Group B (52), 17.8% in Group C (20), and 31.5% in Group D (32). Concomitant RT and 5-FU regional infusion and/or curettage remarkably improved the local control rate. No significant additive effect of 5-FU infusion on T2 and T3 was observed, nor was any usefulness of curettage for T4 in Group B observed. A dose of TDF 90-99 was beneficial for local control rate. The use of 5-FU might reduce irradiation doses optimal to radiation therapy. (N.K.)

  8. Surgical removal of dental implants displaced into the maxillary sinus

    2009-01-01

    Full Text Available The accidental displacement of roots, endodontic materials and dental implants into the maxillary sinus are relatively common complications in dental clinical practice. The purpose of this study is to present four cases of displaced dental implant into maxillary sinus, their treatment as well as the prevention of this condition. There are three different major approaches to remove materials displaced into the maxillary sinus: suction from the socket of an extracted tooth, the classical open surgery via the canine fossa and endoscopic approach. A relevant improvement of surgical techniques previous to, or in association with, the placement of implants in the posterior maxilla, has tremendously expanded the possibilities and indications for such treatments. To decrease the risk for developing side effects, it is recommended that sinus augmentation procedures should be performed before inserting implants in a resorbed upper jaw where sinus penetration is unavoidable. As implant displacement in the paranasal sinuses may be followed by infectious complications, an immediate or early removal of the displaced implants is indicated.

  9. Assessment of the lacrimal recess of the maxillary sinus on computed tomography scans

    International Nuclear Information System (INIS)

    Objective: To assess the frequency of the lacrimal recess in the maxillary sinus (MS) in computed tomography (CT) of the paranasal sinuses. Methods: CT of the paranasal sinuses (CT PNS) done in a total of 78 patients. According to the discoveries, the MS were classified in two types: anterior or lateral. Results: 41 CT PNS of 41 patients of a total of 78 patients preselected were excluded. 37 CT of the paranasal sinuses from 37 patients, in a total of 68 maxillary sinuses were studied. In the 33 right maxillary sinuses, 10 lacrimal recesses were found, 9 from male patients. Eleven left maxillary sinuses with lacrimal recess were found from a total of 35 left maxillary sinuses. Conclusion: From the analysis of 68 MS, a frequency of 30.9% of lacrimal recesses in the maxillary sinuses in CT was observed

    Inflammatory pseudotumor is a well known but poorly understood pathologic entity. It is associated with an unusual growth of fibrotic tissue admixed with varying amounts of inflammation that displaces and compresses normal anatomic structures, resulting in dysfunction. Pseudotumors have been found in multiple locations-the orbit in particular-but to the best of our knowledge, none has previously been reported as an isolated sinus lesion. We describe a case of primary sclerosing fibroinflammatory pseudotumor of the maxillary sinus that manifested as recurrent unilateral maxillary sinusitis in a 47-year-old woman. The patient was managed with surgery and oral steroids with full resolution of her symptoms. We also review the presentation, diagnosis, and treatment of fibroinflammatory pseudotumors within the context of the current literature. PMID:22180112

  13. A study of the distribution pattern and correlation between maxillary, frontal and sphenoid sinus volume

    International Nuclear Information System (INIS)

    In an attempt to study the distribution pattern and correlation between maxillary, frontal and sphenoid sinus volume, sinus volumes were measured by coronal CT scans of the paranasal sinus. Two hundred and four maxillary sinuses of 102 patients, the frontal sinuses of 62 patients and the sphenoid sinuses of 68 patients with no inflammatory changes detectable on CT scans of the each paranasal sinus and nasal cavity were analyzed. The volumes of the maxillary sinus showed a normal distribution, and its mean volume and standard deviation were 20.5±9.2 cm3. The logarithms of both frontal and sphenoid sinus volumes exhibited an normal distribution. The mean volume of the frontal sinus and the sphenoid sinus, which were calculated using logarithms of the sinus volumes statistically, were 8.3 cm3 and 9.6 cm3 respectively. The correlation coefficient was 0.134 between the maxillary and frontal sinus, 0.445 between the maxillary and sphenoid sinus and 0.315 between the frontal and sphenoid sinus. It is suggested that differences in the volume distribution pattern between the maxillary sinus and frontal or sphenoid sinus might be caused by differences in the growing process of each sinus.

    Full Text Available Introduction. Ameloblastomas are clinically the most important type of odontogenic tumors. Solid or multicystic form most commonly affects mandible, it is highly aggressive and shows high rates of recurrence. The aim was to report aggressive behavior of a rare maxillary solid ameloblastoma, emphasizing the clinical, tomographic and histological aspects. Case Report. A young and asymptomatic patient, presenting a solid ameloblastoma initially located in the maxillary sinus with rapid spreading to the adjacent tissues, had early recurrence despite radical surgical approach. Conclusion. Multicystic or solid ameloblastoma has lower incidence in maxilla and extremely aggressive behavior, justifying careful follow-up of the patients.

  16. Oral surgery as risk factor of odontogenic maxillary sinusitis

    Full Text Available In order to determine the risk factors of odontogenic maxillary sinusitis, a total number of 40 patients with this pathological condition was examined in three-year period. Oroantral communication was detected in 40% of patients, oroantral fistula in 25%, sinus foreign bodies in 15% and other pathological conditions in 10% of cases. The extraction of the upper lateral teeth was the cause of odontogenic sinusitis in 65% patients. Given the specific tooth, the first upper molar was the most common cause of the condition, i.e. in 40% of cases. It may be concluded that odontogenic sinusitis is the complication of the oral cavity surgery in 85% of patients, what should be taken into consideration in prevention.

  17. A Computed Tomographic Study on the Size and Bone Wall Thickness of the Maxillary Sinus in Normal, Preoperative and Postoperative Maxillary Sinusitis Patients

    To compare the size and bone wall thickness of the maxillary sinus in normal, preoperative and postoperative maxillary sinusitis patients. The author analyzed CT images of both left and right maxillary sinuses in 357 patients who visited Chonbuk National University Hospital between January 1997 and December 1998. The size and bone wall thickness of the maxillary sinus of normal, inflammatory and post-Caldwell-Luc groups were compared. The significant differences of transverse, maximum medio-lateral, maximum supero-inferior dimensions and medio-lateral dimension at nasal floor level between normal and post-Caldwell-Luc groups were found (P0.05). The significant differences of postero-lateral, infero-lateral and medial wall thickness between normal and post-Caldwell-Luc groups were found (P<0.05). The results of this study will aid in the diagnosis and treatment of maxillary sinus diseases and post operative treatment planning.

    Olfactory neuroblastoma (ONB) is a rare malignant tumor. Although the vast majority of cases arise in the nasal cavity, ONB is rarely reported in ectopic locations. We report a case of ONB in the maxillary sinus. A 63-year-old woman presented with left-sided nasal obstruction and epistaxis. Magnetic resonance imaging showed a nonenhancing left maxillary sinus tumor. Histologic sections showed ONB, Hyams grade IV, invading bone, skeletal muscle, and adjacent fibroadipose tissue. It is essential to be accurate when diagnosing sinonasal tumors because the differential diagnosis is broad, and one must consider the possibility of ectopic ONB, although it is rare. The behavior of ONB and other neuroendocrine tumors of the sinonasal region is quite different, and there are varied approaches to treatment. Therefore, an accurate diagnosis as well as correct grade and stage must be assigned. PMID:27180059

  19. X-ray examination in cysts of the maxillary sinuses

    International Nuclear Information System (INIS)

    A procedure of X-ray examination in cysts of the maxillary sinuses is considered. A comparative evaluation of the results of radiography and zonography in 185 patients (244 cysts) has shown that from the diagnostic point of view zonography is more effective making it possible to detect a cyst irrespective of its size. False data as to the presence of cysts in straight radiography were obtained in 79.3% of the cases. However zonography alone does not allow one to differentiate between cysts of rhenogenous and odontogenous nature. Supplementary radiographic examination of the upper denture (enlarged panoramic radiography and orthopantomography) in 100 out of 123 patients made it possible to solve the problem of cyst origin. Enlarged panoramic radiography probvides more information on the state of the periradical cyst and surrounding osseous tissue as well as the osseous walls of the bottom of the alveolar bay. The ingrowing of the cyst into the maxillary sinus is better revealed in orthopantomograms

  20. A combined study of CT and MRI in chronic maxillary sinusitis

    International Nuclear Information System (INIS)

    With CT of the paranasal sinusitis mucosal swelling can not be distinguished from fluid accumulation within the sinuses in patients with chronic sinusitis. We studied 12 cases of chronic sinusitis (17 sides) by means of CT and MRI, with which we could distinguish mucosal swelling from fluid accumulation in the maxillary sinuses. It was found that in a majority of cases with total clouding of the maxillary sinus the degree of swelling of mucous membrane was relatively small. This indicates that the main cause of total clouding of the maxillary sinus found in CT is due to accumulation of fluid rather than from obliteration of the sinus due to swelling of mucous membrane within the maxillary sinus.

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

    A cystic compound odontoma in the maxillary sinus occurred in a 13-years-old boy, who had missing right upper third molar without having the history of extraction of the wisdom tooth. He complained nasal stuffiness, headache, and pain on the affected face, resembling any sign and symptoms of the maxillary sinus problems. The cysteic compound, sized 2 x 1.5 cm in diameter was pedunculated and attached on the posterior wall of the right maxillary sinus and above the antral floor. The location of the compound odontoma in the maxillary sinus was confirmed after panoramic, waters, spiral tomographic, CT examinations and surgical exploration. Irs location was on the medical, posterior, superior to the normal position of the maxillary third molar or the maxillary dental arch. The cystic odontoma in the maxillary sinus made the patient have the sings and symptoms of maxillary sinusitis. The cystic compound odontoma might be originated from the dental lamina of the missing upper right third molar. The 'V principle' of the upper jaw growth and the pneumatization process of the maxillary sinus could explain why the compound odontoma had peduncular shape and the location of odontoma was on the medial, superior to the normal position of the maxillary dental arch.

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

    Metallic foreign bodies are rarely found in the maxillary sinus, and usually they have a dental origin. Two main surgical app-roaches are currently used for the removal of foreign bodies in the maxillary sinus: the bone flap and the endoscopic sinus tech-niques. However, the treatment is not only surgical removal. We are reporting one case of foreign body like a hand sewing needle entered into the maxillary sinus through an unusual route- carious deciduous molar tooth. It was diagnosed by three-dimensional images from cone-beam computed tomography (CBCT) and removed by a simple procedure, with magnetic iron, thereby avoiding the risk of damage to a large portion of the alveolar bone near the maxillary sinus.

    Foreign bodies in paranasal sinuses are very rare and most of them are encountered in the maxillary sinus. These foreign bodies may be organic or inorganic and can enter the maxillary sinus through an oro-antral fistula. The oro-antral fistula is formed by a break in the bony segment of the maxillary sinus floor and usually arises subsequent to maxillary premolar and molar extractions. A 63-year-old female patient evaluated for a nonhealing, left, toothless palate lesion and chronic headache occurring over 4 years. Radiography and computed tomography revealed bone discontinuity in the left floor of the maxillary sinus and calcifications within the antrum. A blue foreign body, later identified as dental impression material, was removed by intranasal endoscopy. A careful oral examination is recommended prior to prosthetic restorations. In addition, paranasal sinus foreign bodies should be surgically removed to prevent secondary soft tissue reactions. PMID:26856299

  8. Evaluation of the postoperative maxillary sinus with computed tomography

    International Nuclear Information System (INIS)

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

    Physicochemical characteristics of a biomaterial directly influence its biological behavior and fate. However, anatomical and physiological particularities of the recipient site also seem to contribute with this process. The present study aimed to evaluate bone healing of maxillary sinus augmentation using a novel bioactive glass ceramic in comparison with a bovine hydroxyapatite. Bilateral sinus augmentation was performed in adult male rabbits, divided into 4 groups according to the biomaterial used: BO-particulate bovine HA Bio-Oss(®) (BO), BO+G-particulate bovine HA + particulate autogenous bone graft (G), BS-particulate glass ceramic (180-212 ?m) Biosilicate(®) (BS), and BS+G-particulate glass ceramic + G. After 45 and 90 days, animals were euthanized and the specimens prepared to be analyzed under light and polarized microscopy, immunohistochemistry, scanning electron microscopy (SEM), and micro-computed tomography (?CT). Results revealed different degradation pattern between both biomaterials, despite the association with bone graft. BS caused a more intense chronic inflammation with foreign body reaction, which led to a difficulty in bone formation. Besides this evidence, SEM and ?CT confirmed direct contact between newly formed bone and biomaterial, along with osteopontin and osteocalcin immunolabeling. Bone matrix mineralization was late in BS group but became similar to BO at day 90. These results clearly indicate that further studies about Biosilicate(®) are necessary to identify the factors that resulted in an unfavorable healing response when used in maxillary sinus augmentation.

  10. Maxillary sinus 3D segmentation and reconstruction from cone beam CT data sets

    International Nuclear Information System (INIS)

    Purpose: Segmentation of the maxillary sinuses for three-dimensional (3D) reconstruction, visualization and volumetry is sought using an automated algorithm applied to cone beam computed tomographic (CBCT) data sets. Materials and methods: Cone beam computed tomography (CBCT) data sets of three subjects aged 9, 17, and 27 were used in 3D segmentation and reconstruction. The maxillary sinuses were obtained by propagation from one start point in the right sinus and one start point in the left sinus to the whole regions of both sinuses. The procedure was based on voxel intensity distributions and common anatomic structures, specifically each middle meatus of the nasal cavity. A program was written in C++ and VTK languages to demonstrate the surface topological shapes of the maxillary sinuses. Results: The developed segmentation algorithm separated maxillary sinuses successfully permitting accurate comparisons. It was robust and efficient. 3D morphological features of the maxillary sinuses were observed from three human subjects. Conclusions: Automated segmentation of maxillary sinuses from CBCT data sets is feasible using the proposed method. This tool might be useful for visualization, pathological diagnosis, and treatment planning of maxillary sinus disorders. (orig.)

  11. Radiotherapy for carcinomas of the paranasal sinus (excluding the maxillary sinus)

    International Nuclear Information System (INIS)

    Thirty-seven patients with carcinomas of the nasal cavity and paranasal sinuses (excluding the maxillary sinus) were treated with radiotherapy with or without surgery at Jikei University Hospital from 1979 through 1994. Of these patients (14 with carcinomas in the nasal cavity, 17 in the ethmoid sinus, and 6 in the sphenoid sinus), 16 were treated with radiotherapy alone and 21 with both surgery and radiotherapy. The patients received median doses of 60 Gy for radiotherapy alone, 41 Gy for preoperative radiotherapy, and 51 Gy for postoperative radiotherapy. The 2-year local control rates in stages I and II were 60% with radiotherapy alone (75% if the dose was 60 Gy or more) and 57% with combined therapy. We conclude that tumors of stages I and II showing at least a partial response to a dose of 40 Gy should be treated with full-dose radiotherapy. (author)

    Full Text Available Abstract Background We have previously proposed the use of Doppler ultrasound to non-invasively stage sinus infection, as we showed that acoustic streaming could be generated in nonpurulent sinus secretions and helped to distinguish it from mucopurulent sinus secretions. In order to continue this development of a clinically applicable Doppler equipment, we need to determine different dimensions of the paranasal sinuses, especially the thickness of the anterior wall of the maxillary sinus (at the canine fossa. To the best of our knowledge, this is the first report on the thickness of the canine fossa. This study aimed to (a estimate different dimensions of the maxillary and frontal sinuses measured on computed tomography (CT of the head, (b define cut-off values for the normal upper and lower limits of the different measured structures, (c determine differences in age, side and gender, (d compare manually and automatically estimated maxillary sinuses volumes, and (e present incidental findings in the paranasal sinuses among the study patients. Methods Dimensions of 120 maxillary and frontal sinuses from head CTs were measured independently by two radiologists. Results The mean value of the maxillary sinus volume was 15.7 ± 5.3 cm3 and significantly larger in males than in females (P = 0.004. There was no statistically significant correlation between the volume of maxillary sinuses with age or side. The mean value of the bone thickness at the canine fossa was 1.1 ± 0.4 mm. The automatically estimated volume of the maxillary sinuses was 14-17% higher than the calculated volume. There was high interobserver agreement with regard to the different measurements performed in this study. Different types of incidental findings of the paranasal sinuses were found in 35% of the patients. Conclusion We presented different dimensions of the maxillary and frontal sinuses on CTs. We believe that our data are necessary for further development of a clinically applicable Doppler equipment for staging rhinosinusitis.

    Full Text Available Introduction: Ameloblastic fibro-odontoma is a rare, benign, asymptomatic tumor. The term ameloblastic fibro-odontoma was first used by Hooker in 1967 as a separate lesion from ameloblastic odontoma.   Case Report: This case report describes an eleven years old female with large ameloblastic fibro-odontoma in the right maxillary sinus.   Conclusion: There is a low potential for recurrence after complete Enucleation of ameloblastic fibro-odontoma, but due to the risk of ameloblastic sarcoma after recurrence, the surgery should be perfect along with a careful follow up. 

  15. Maxillary sinus marrow hyperplasia in sickle cell anemia

    International Nuclear Information System (INIS)

    Marrow hyperplasia is a sequela of sickle cell anemia (SCA) and may be seen in the skull in children after 5 years of age. The facial bones, except for the mandible and orbits, are usually not involved. We report an unusual case of a 28-month-old black boy with SCA who presented with extensive marrow hyperplasia of the maxillary sinuses in addition to severe calvarial and mandibular changes. The imaging characteristics on CT (similar to other sites of marrow hyperplasia) and MR (low signal on both T1 and T2 sequences) should aid in making the correct diagnosis. (orig.)

    The morphometric analysis of maxillary sinus was recently presented as a helpful instrument for sex determination. The aim of the present study was to examine the volume and surface of the fully dentate, partial, and complete edentulous maxillary sinus depending on the sex. Computed tomography data from 276 patients were imported in DICOM format via special virtual planning software, and surfaces (mm) and volumes (mm) of maxillary sinuses were measured. In sex-specific comparisons (women vs men), statistically significant differences for the mean maxillary sinus volume and surface were found between fully dentate (volume, 13,267.77 mm vs 16,623.17 mm, P?event through the increase in pneumatization.

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

    Foreign bodies in maxillary sinuses are unusual clinical conditions, and they can cause chronic sinusitis by mucosal irritation. Most cases of foreign bodies in maxillary sinus are related to iatrogenic dental manipulation and only a few cases with non-dental origin are reported. Oroantral fistulas secondary to dental procedures are the most common way of insertion. Treatment is surgical removal of the foreign body either endoscopically or with a combined approach, with Caldwell-Luc procedure...

  2. A Radiologic Study of the Relationship of the Maxillary Sinus Floor and Apex of the Maxillary Molar

    International Nuclear Information System (INIS)

    In this study, radiographic evaluation was made using panoramic radiography and cross-sectional tomography of SCANORA in male and female adults in their 20 s on the relationship between the maxillary sinus floor and the apex of the maxillary molar, to test the accuracy and effectiveness of the cross-sectional tomography, and to use this information in the assessment of preop, and postop, root canal treatment, apical surgery, extraction and implantology. Forty-one adults with an average age of 24.4 years were studied panoramic radiography and cross-sectional tomography. In panoramic view and cross-sectional view, the position of the apices of maxillary molars were classified as separated, contacted, or protruded type; the general shape of the maxillary sinus floor was evaluated horizontally and vertically from cross-sectional tomography. The accuracy of each radiography was tested using maxilla from 5 fresh cadavers from the Anatomy Lab at Yonsei University Dental College, and panoramic view and cross-sectional tomography were taken in the same condition as with the patients. The results were as follows ; 1. Panoramic view and cross-sectional view were taken in the maxilla specimen, and the actual distance between the maxillary sinus floor and the tooth apices were measured in the specimen; the median values of the distance from the tooth apices to the maxillary sinus floor in the panoramic view, cross-sectional view and in the accrual maxilla specimen were 2.83 mm, 4.51 mm, and 4.15 mm, respectively. In the cross-sectional view, the measured distance was close to the actual distance but in the panoramic view, the measured distance was far from the actual distance. 2. When the results of the panoramic view and cross-sectional view were compared, 40.5% of the results agreed with each other in the two radiographic methods and buccal roots of the 2nd molar were the closest to the maxillary sinus floor in the cross-sectional tomography.3. In cross-sectional view, when the vertical relationship of the maxillary sinus floor and maxillary roots was assessed, in 1st molars, type II (the sinus floor that extends down to the buccolingual furcation area) was predominant, while in 2nd molars, type I (the sinus floor located above the level connecting the buccal and lingual apices) was predominant. In the horizontal relationship, in 1st olars, type II (ths lowest floor of the maxillary sinus located in between the buccal and lingual roots) was predominant; in 2nd molars, type I (the lowest floor of the maxillary sinus located on the buccal side of the buccal roots) and type II appeared in similar frequency. In conclusion, the SCANORA cross-sectional tomography was more effective than the frequently used panoramic view, in that the relationship of the maxillary molars and maxillary sinus floor can be evaluated more accurately and the buccolingual cross-sectional view can also be observed. And maxillary sinus floor that was close to maxillary 2nd molar had tendency to be located on buccal side than that close to 1st molar. Therefore, cross-sectional tomography is an effective and accurate method to evaluate the position of the teeth in relation to the sinus floor preoperative and can be easily used to diagnose localized periapical lesions. Also the image quality obtained was quite satisfactory.

  4. Radiodense concrements in sinus maxillaris-CT diagnosis of sinus aspergillosis

    International Nuclear Information System (INIS)

    11 patients with radiodense concrements in the sinus maxillaris underwent a preoperative computertomographic examination of the sinus maxillaris and the sinus concrements. 8 patients (72.7%) with the occurrence of radiodense concrements presented postoperative a histological and microbiological infection with aspergillus fumigatus. The CT-numbers of radiodense concrements in patients with aspergillus were 2802±302.4 HU (Hounsfield Unit). Concrements of patients without aspergillus infection (n=3) had lower density (368.6±149.1 HU; p<0.001). The root filling materials showed narly the same CT-numbers in patients with aspergillus infection (2537±398.5 HU) and in patients without aspergillus infections (2544.3±460.6 HU). Density of root filling material was at the same level as density of radiopaque concrements in patients with aspergillus infections. According to CT-examinations a direct connection between root filling materials and aspergillus infection was noted. Therefore in patients with radiodense concrements computertomographic examination helps to determine the kind of sinus infection. (orig.)

    The purpose of this study was to evaluate the ability of radiographs in detecting experimental bony defect in the posterior wall of the maxillary sinus. For this study, experimentally five skulls were used, the bony defects with a diameter of 5 mm were created at different locations in the posterior wall of the right maxillary sinus and the bony defects of 10 mm were created at different locations in the posterior wall on left maxillary sinus. Panoramic view, panoramic sinus view, water's view, and computed tomogram were taken and the results analyzed. The obtained results were as follows : 1. The panoramic view was superior to the panoramic sinus view in detecting the bony defects in the posterior wall of the maxillary sinus. 2. Panoramic view, panoramic sinus view, and waters' view were limitation to the detection of the bony defects in the posterior wall of the maxillary sinus. 3. All the bony defects in the posterior wall of the maxillary sinus were excellently visualized on the computed tomogram.

    Bone tissue atrophy may constitute a relative contraindication for implantation. The methods used in reconstruction of the alveolar ridge within the lateral section of the maxilla have been well known but not perfect. Presentation of the two-stage, closed sinus lift technique as well as efficacy evaluation of reconstruction of the alveolar ridge in the maxilla within its vertical dimension with the use of this technique. The total procedure was performed in 26 out of 28 patients qualified for the study. The height of the alveolar ridge at the site of the planned implantation was no treatment stage 1 the sinus lift was performed for the first time. The created hollow was filled with allogeneic granulate. After 3-6 months stage 2 was performed consisting in another sinus lift with simultaneous implantation. The treatment was completed with prosthetic restoration after 6 months of osteointegration. In 24 out of 26 cases stage 1 was completed with the average ridge height of 7.2 mm. In stage 2, simultaneously with the second sinus lift, 26 implants were placed and no cases of sinusitis were found. In the follow-up period none of the implants were lost. The presented method is efficient and combines the benefits of the open technique-allowing treatment in cases of larger reduction of the vertical dimension and the closed technique-as it does not require opening of the maxillary sinus.

  8. A pitfall in treatment planning for maxillary sinus tumor

    International Nuclear Information System (INIS)

    Typical treatment techniques are evaluated with a couple of humanoid phantom and TLD rods. Arbitary score is estimated at every measured point according to the three dimensional anatomical arrangement in the phantom, in order to evaluate the efficacy of each treatment plan. The excellent score is achieved by the technique with combination of 2-p wedge pair for maxillary sinus and 15 MeV electron for ethmoid sinus and adjacent nasal cavity. The second best is the 3-axial conformal plan, followed by oblique irregular wedge plan and the single axial conformal technique: the series of mono block wedge pair techniques are rather poor in dose efficacy. The existence of an underspot in the ethmoid sinus in the combination technique indicates that a careful consideration has to be given to the energy level of electron beam and the anatomical localization of the target volume. Differences between measured doses and planned doses are large: 5 to 13 % in the three dimensional dose distribution. (author)

The author analysed the anterior-posterior width of mesial wall, the extension of anterior margin in maxillary sinus and the interrelation between the root apex of maxillary 1st molar and sinus floor. The films consisted of 514 orthopantomograms divided into three groups ranging the 3rd decade, 4th and 5th decade and 6th decade. The obtained results were as follows: 1. The mean dimensions of the anterior-posterior width of mesial wall were 43.81 ± 4.55 mm for male and 43.80 ± 4.49 mm for female in the right of maxillary sinus, 43.75 ± 4.74 mm for male and 43.37 ± 3.92 mm for female. 2. With age, the dimensional change of the anterior-posterior width of mesial wall in maxillary sinus was not observed. 3. The extension order of anterior margin of the maxillary sinus was distal to canine side, 1st premolar mesial side, canine mesial side, and 1st premolar distal side. 4. In the distance between the root apex of upper 1st molar and the maxillary sinus floor, the degree of closeness was more increased in the older-aged group than in the younger-aged group.

    Diagnosing sinusitis remains a challenge for primary care physicians. There is a need for a simple, office-based technique to aid in the diagnosis of sinusitis without the cost and radiation risk of conventional radiologic imaging. We designed a low-cost near-infrared (NIR) device to transilluminate the maxillary sinuses. The use of NIR light allows for greater interrogation of deep-tissue structures as compared to visible light. NIR imaging of 21 patients was performed and compared with computed tomography (CT) scans. Individual maxillary sinuses were scored on a scale from 0 to 2 based on their degree of aeration present on CT and similarly based on the NIR signal penetration into the maxilla on NIR images. Our results showed that air-filled and fluid/tissue-filled spaces can be reasonably distinguished by their differing NIR signal penetration patterns, with average NIR imaging scores for fluid-filled maxillary sinuses (0.93+/-0.78, n=29) significantly lower than those for normal maxillary sinuses (1.62+/-0.57, n=13) (p=0.003). NIR imaging of the sinuses is a simple, safe, and cost-effective modality that can potentially aid in the diagnosis of sinusitis. Long-term, significant device refinement and large clinical trials will be needed to determine the diagnostic accuracy of this technique.

    This study describes the CT findings of changes in the maxillary sinus after the Caldwell-Luc procedure. The maxillary sinus-related findings in 35 cases among 20 patients (17 cases in 10 males and 18 cases in 10 females) who had undergone the Caldwell-Luc procedure mean 14.6 years earlier were reviewed. CT scans were obtained in the axial and coronal planes, with 5mm thickness. By means of the T test, changes in the size of the bony wall of the maxillary sinus, as well as antral volume change, were compared with normal maxillary sinus group (41 male and 23 female cases). Males and females were compared separately, and surgical bony defect of naso-labial antrotomy and nasoantral window, fibro-osseous proliferation, compartmentation and mucosal thickening of the postoperative maxillary sinus were evaluated, as were findings of chronic or recurrent maxillary sinusitis and postoperative complications. Naso-labial antrotomy was clearly identified in 27 of 35 cases, and irregular bony surface in the remaining eight, as were 27 bony defects and one irregular bony margin among a total of 28 cases of nasoantral window. Due to shortening of the height of the orbit, reductions in maxillary width, nasoantral communication width and anteroposterior diameter of the maxilla, and widening of the width of the inferior meatus, the maxillary sinus tended to become hypoplastic and centripetally contracted. Reduced cavitary volume of the maxillary sinus was noted (p less than 0.05), and fibro-osseous proliferation (n=3D29), compartmentation (n=3D11), and mucosal thickening (n=3D22) of the postoperative maxillary sinus were also seen. There were findings of chronic sinusitis (n=3D22), as well as complications of postoperative mucocele (n=3D3) and oroantral fistula (n=3D2) of the maxillary sinus. The characteristic maxillary sinus-related findings seen after the Caldwell-Luc procedure are helpful in distinguishing postoperative change from recurrent paranasal diseases and resulting complications.

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

    Full Text Available Introduction Calcifying odontogenic cyst (COC is an uncommon odontogenic lesion, classified in two variants: the cystic variant and neoplastic (solid variant. Case Presentation This case report presents multiple COC, which involved the maxillary bone and sinus in a 30-year-old man. Several of these lesions were cystic, while the others were neoplastic in type, and the lesions were removed surgically. Discussion Based on a literature review available on this topic in English, our case study was found to be the first one with multiple COC, showing both the cystic and neoplastic histopathological variant. Considering the high rate of recurrence of neoplastic COC, the patients should benefit from a long follow-up after treatment.

  15. Radiotherapy of maxillary sinuses carcinoma: state of art

    International Nuclear Information System (INIS)

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

    To compare the size and bone wall thickness of the maxillary sinus in normal, preoperative and postoperative maxillary sinusitis patients. The author analyzed CT images of both left and right maxillary sinuses in 357 patients who visited Chonbuk National University Hospital between January 1997 and December 1998. The size and bone wall thickness of the maxillary sinus of normal, inflammatory and post-Caldwell-Luc groups were compared. The significant differences of transverse, maximum medio-lateral, maximum supero-inferior dimensions and medio-lateral dimension at nasal floor level between normal and post-Caldwell-Luc groups were found (P<0.05). And the significant differences of antero-posterior dimensions between inflammatory and post-Caldwell-Luc group were found (P<0.05). But, no significant differences of vertical height dimensions between groups was found (P>0.05). The significant differences of postero-lateral, infero-lateral and medial wall thickness between normal and post-Caldwell-Luc groups were found (P<0.05). The results of this study will aid in the diagnosis and treatment of maxillary sinus diseases and post operative treatment planning.

    This case report describes the successful orthodontic tooth movement through the maxillary sinus in an adult patient. A 41-year-old Asian woman had severe lip protrusion and multiple missing posterior teeth. Her orthodontic treatment included the extraction of two teeth, maximum retraction of the incisors using the extraction spaces and the existing spaces from the missing molars, and closure of all remaining spaces. Even though the treatment time was extended because of the anatomic and biologic challenges associated with moving posterior teeth over a long distance through the maxillary sinus, a successful outcome was obtained, with significant bone modeling of the maxillary sinus. The results demonstrate that a carefully selected force system can overcome the anatomic limitations of moving tooth against the cortical bone of the maxillary sinus wall in adult patients.

  2. Disappearance of a dental implant after migration into the maxillary sinus: an unusual case

    Science.gov (United States)

    2015-01-01

    Migration of dental implants into the maxillary sinus is uncommon. However, poor bone quality and quantity in the posterior maxilla can increase the potential for this complication to arise during implant placement procedures. The aim of this report is to present a dental implant that migrated into the maxillary sinus and disappeared. A 53-year-old male patient was referred to us by his dentist after a dental implant migrated into his maxillary sinus. The displaced implant was discovered on a panoramic radiograph taken five days before his referral. Using computed tomography, we determined that the displaced dental implant was not in the antrum. There was also no sign of oroantral fistula. Because of the small size of the displaced implant, we think that the implant may have left the maxillary sinus via the ostium. PMID:26568932

  7. Radiotherapy for cancer of the maxillary sinus, with boost therapy by low dose rate intracavitary irradiation

    International Nuclear Information System (INIS)

    Prognosis of cancer of the maxillary sinus markedly depends on its local control. In order to increase the local control rate for cancer of the maxillary sinus, low dose rate intracavitary irradiation of the maxillary sinus was performed as boost therapy of external irradiation. During the period from January 1975 through September 1982, 87 patients with cancer of the maxillary sinus were treated by radiotherapy at the Department of Radiology, The Jikei University School of Medicine, and 43 out of these 87 cases were treated with intracavitary irradiation as boost therapy of external irradiation. The 3-year and 5-year cumulative survival rates of the 43 cases treated with intracavitary irradiation were 44% and 39%, respectively. The same two rates of the 44 cases without intracavitary irradiation were both 47%. Considering that tumor foci still persisted in the maxillary sinus in almost all of the 43 intracavitary irradiation cases and that 34 of them were of the postero-superior type (according to Oehngren's classification), which generally results in poor prognosis, intracavitary irradiation as boost therapy can be assumed to be one of the effective therapeutic techniques for cancer of the maxillary sinus.

    2015-01-01

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

    The aim of this study was to investigate the initial effects of maxillary expansion therapy with Hyrax appliance and to evaluate the related changes in maxillary sinus volume. Thirty patients (20 females, 10 males; 13.8 years) requiring maxillary expansion therapy, as part of their comprehensive orthodontic treatment, were examined. Each patient had cone-beam computed tomography (CBCT) images taken before (T1) and after (T2) maxillary expansion therapy with a banded Hyrax appliance. Multiplanar slices were used to measure linear dimensions and palatal vault angle. Volumetric analysis was used to measure maxillary sinus volumes. Student t tests were used to compare the pre- and post-treatment measurements. Additionally, differences between two age groups were compared with Mann-Whitney U test. The level of significance was set at p=0.05. Comparison of pre-treatment to post-treatment variables revealed significant changes in the transverse dimension related to both maxillary skeletal and dental structures and palatal vault angle, resulting in a widened palatal vault (p<0.05). Hard palate showed no significant movement in the vertical and anteroposterior planes. Nasal cavity width increased on a mean value of 0.93 mm(SD=0.23, p<0.05). Maxillary sinus volume remained virtually stable. No significant age differences were observed in the sample. Hyrax expansion therapy did not have a significant impact on maxillary sinus volume.

    Endoscopic sinus surgery (ESS) widely conducted in nasal and paranasal sinus surgery provides superior magnification, illumination, and angled visualization, enabling the surgeon to isolate the tumor base and accurately define disease extent. Endoscopic medial maxillectomy (EMM), an advanced ESS procedure, effectively treats benign sinonasal neoplasms such as inverted papilloma. We analyzed a series of EMM cases and their clinical outcomes, including 9 inverted papillomas, 1 solitary fibrous tumor, 1 hemangioma, 1 blood boil and 1 esthesioneuroblastoma. EMMs were conducted by an experienced surgeon. Removal of the medial wall and the wide maxillary sinus opening enabled by EMM allows easy access to the entire maxillary sinus with a generous work space. All tumors were treated endoscopically and the postoperative course was uneventful. No recurrence was observed in follow-up. We found EMM to be safe and efficacious in resecting maxillary sinus tumors thanks to its improved accessibility and visualization. In conclusion, EMM enables complete removal of benign tumors from the maxillary sinus, having the advantages of no external incision, decreased blood loss, low morbidity, shorter hospital stay, and the possibility of repetition in recurrence, compared to conventional approaches. EMM may thus become the treatment of choice for maxillary sinus tumors. PMID:20225704

  12. Morphological study of the maxillary sinus using three-dimensional reconstruction of the tomographic images

    International Nuclear Information System (INIS)

    A morphological study of the maxillary sinus using the computerized three-dimensional reconstruction of the tomographic images was made. Materials of this study were 86 adult dry skulls of the Second Department of Oral Anatomy of Fukuoka Dental College. The results were as follows: 1. A tomographic apparatus which could select varius X-ray tube shifts was used. The hypocycloidal shift was the best for the tomography of the maxillary sinus. 2. In the tomographs of the maxillary sinus, the images of some sections in the maximum cross-section area presented real shapes. However, the images of other sections were indistinct and influenced by the shape of the maximum cross-section. 3. Reconstruction of the tomographic images of the maxillary sinus by computer made it easy and precise to recognize the three-dimensional image. 4. The dimensions in the maximum cross-section of the maxillary sinus of the 86 adult dry skulls obtained from the reconstructed three-dimensional images were 4.59 ± 1.26 cm2 in frontal, 5.21 ± 1.36 cm2 in transversal and 8.09 ± 1.82 cm2 in sagittal tomographs. The majority of the skulls were symmetry, and a few were asymmetry in correlation between the right and left side sinuses. 5. According to the reconstructed three-dimensional images the shapes of the maxillary sinus of the 86 adult dry skulls were classified into 10 types in frontal, 4 types in transversal and 8 types in sagittal tomographs. The most familiar shape was triangular in frontal, trapezoidal in sagittal and triangular in transversal tomographs. 6. The dimension and shape of the maxillary sinus had no correlation with the frontal width of the nasal cavity. (author)

    International Nuclear Information System (INIS)

    This report was to show the radiographic appearances of the fungus ball in a paranasal sinus and to emphasize the scan area of cone beam computed tomography (CBCT) to detect the calcification in the paranasal sinus. A seventy four-year-old woman visited our department for the implant rehabilitation at both maxillary posterior edentulous region. Pre-operative radiographic examinations including the panoramic, CBCT, and multidector CT images were taken. An opacification in the right maxillary sinus was observed on the multiplanar image of CBCT, however the pre-determined scan area of CBCT in this report hardly showed the calcifications at the central portion of the maxillary sinus. The opacification in the maxillary sinus could be misdiagnosed as chronic maxillary sinusitis if the calcification of fungus ball was not simultaneously detected. The scan area of pre-operative CBCT needs to be enough to scan the paranasal sinus from top to bottom.

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

  18. Comparison of panoramic radiography and cone beam computed tomography for assessing the relationship between the maxillary sinus floor and maxillary molars

    International Nuclear Information System (INIS)

    This study compared panoramic radiography and cone beam computed tomography (CBCT) for evaluating the relationship between the maxillary sinus floor and the roots of maxillary molars. Paired panoramic radiographs and CBCT images from 97 subjects were analysed. This analysis classified 388 maxillary molars according to their relationship to the maxillary sinus floor on panoramic radiograph and CBCT. Correlations between these two radiographic techniques were examined. Maxillary molar roots that were separate from the sinus floor showed the same classification in 100% of the cases when using these two imaging techniques. The corresponding percentage for such roots that were in contact with the sinus floor was 75%. When roots overlapped the maxillary sinus floor on panoramic radiographs, only 26.4% of maxillary first molars and 60.0% of second molars showed protrusion of roots into the sinus with CBCT. The results of the study suggest that roots projecting into the sinus on panoramic radiographs require a three-dimensional image in order to analyze the proximity of their apex to the sinus floor.

    Full Text Available PURPOSE: To evaluate the efficacy of associating techniques of bone grafting in the maxillary sinus with the use of a prototyped surgical guide for planning and positioning dental implants in total edentulous maxillae, rehabilitated after six months. METHODS: Eight patients consecutives with totally [...] edentulous maxilla presenting few remaining bone in the posterior alveolar ridge, associated with pneumatization of the maxillary sinus were selected. Twenty eight Brånemark RP 10mm implants were installed in 14 maxillary sinuses. The surgical planning for the implant installation was performed with the DentalSlice software by means of a computerized tomography. The obtained images were used for building a surgical guide that, placed over the maxilla, showed the exact position for the implants installation (prototyped surgical guide). The portion of the implants that went into the maxillary sinus was covered by an autogenous bone graft. RESULTS: The patients were re-evaluated six months after the surgery and a 100% success rate was achieved. All of the implants presented no mobility or symptoms, permitting an oral rehabilitation with total fixed screw-retained prosthesis over the implants. CONCLUSION: The technique of associating implants and bone graft in the maxillary sinus aided by a prototyped guide planned on DentalSlice has showed itself efficient for positioning implants and for quantifying and locating the bone graft.

  20. Inflammatory myofibroblastic tumour of the maxillary sinus: CT and MRI findings

    International Nuclear Information System (INIS)

    Aim: To characterize the computed tomography (CT) and magnetic resonance imaging (MRI) findings of inflammatory myofibroblastic tumours (IMTs) of the maxillary sinus. Materials and methods: The imaging findings of eight patients with IMTs of the maxillary sinus were reviewed retrospectively. Of the eight patients, four patients underwent unenhanced and contrast-enhanced CT, and one patient underwent unenhanced CT only; three patients underwent unenhanced and contrast-enhanced MRI. Results: Five cases of IMTs occurred in the left maxillary sinus, while three cases were right-sided. Four cases occupied the entire sinus, and the other four cases only partially occupied the sinus. Unenhanced CT images showed heterogeneous masses in four cases and a homogeneous mass in one case. One of the tumours showed some areas of calcification. T1-weighted MRI images showed isointense lesions. T2-weighted images showed mixed isointense and mild hyperintense lesions. All cases showed bone destruction and had infiltrated into the nasal fossa, orbit, infratemporal fossa, and other adjacent tissues. Seven cases showed mild to moderate heterogeneous enhancement on contrast-enhanced CT or T1-weighted MRI images. Conclusion: IMTs of the maxillary sinus can be characterized as a soft-tissue mass with bony destruction and infiltration of the adjacent tissues, with mild to moderate enhancement after the injection of contrast medium. CT and MRI can help to diagnose IMTs, determine the extent of the lesion and its relationship with adjacent tissues, and thus facilitate the prediction of surgical resectability.

    Foreign bodies (FBs) in the paranasal sinuses are rare, whether iatrogenic or traumatic. One of the most common causes of such traumatic injuries is gunshot wounds from the bullets. Removing FBs from the paranasal sinuses usually needs endoscopic or open surgery. We present the case of a 22-year-old male soldier who sustained a penetrating injury of his nose and maxillary sinus with an iron rod that was a part of his gun, which was removed without either endoscopic or open paranasal sinus surgery.

    2014-01-01

    Full Text Available Background: The study of anthropometric characteristics is of fundamental importance to solve problems related to identification. Craniometrical features are included among these characteristics, which are closely connected to forensic dentistry. Radiography is used in forensic for the identification of humans especially in cases where the body is decomposed, fragmented, or burned. Radiology can assist in giving accurate dimensions for which certain formulae can be applied to determine the gender. It has been reported that maxillary sinuses remain intact, although the skull and other bones may be badly disfigured in victims who are incinerated and therefore, that maxillary sinuses can be used for identification. Aim: This study has been carried out to check the accuracy and reliability of maxillary sinus in gender determination using morphometric parameters. Materials and Methods: Lateral cephalogram of 50 subjects (25 males and 25 females were taken and morphometric parameters of maxillary sinus were analyzed using AutoCAD 2010 software (Autodesk, Inc.. Results: The mean area and perimeter of maxillary sinus in males was 1.7261 cm 2 and 5.2885 cm whereas, the mean area and perimeter in females was 1.3424 cm 2 and 4.3901 cm. In-group centroids if someone′s discriminant function (DF score is close to 0.838 then the subject are supposed to be male. Whereas, those having DF score closer to −0.838 are supposed to be females. DF analysis showed that, 76% of the original grouped cases were correctly classified. Hence, the overall sensitivity and specificity was found to be 80% and 72%. Conclusion: It can be concluded that morphometric analysis (area and perimeter of maxillary sinus using AutoCAD 2010 software can assist in gender determination.

    Full Text Available We report a case of a neuroendocrine carcinoma arising in a wound of the postoperative maxillary sinus that was difficult to distinguish from a postoperative maxillary cyst. The patient was a 65-year-old Japanese woman who complained of left exophthalmos with cheek swelling and eye movement disorders. In past history, she had, 40 years previously undergone operation on the bilateral maxillary sinus by Caldwell-Luc’s method. In a preoperative computed tomography, a mass occupied the left maxillary sinus showing irregular densities with destruction of the posterior bone walls and invasion into the left orbital. Both TI and T2 weighted magnetic resonance imaging showed low intensities and unevenness in the mass. We performed a biopsy of the maxillary tumor according to Caldwell-Luc’s method. Histological examination diagnosed neuroendocrine carcinoma. Radiation therapy (total 66Gy resulted in partial response for this tumor. However, sinonasal neuroendocrine carcinoma has been identified as highly aggressive, with a high probability of recurrence and metastasis.

    Full Text Available Introduction: Biological matrix has received special attention in recent medical and biological researches. Cells of tissue are supported by extracellular matrix (ECM. Extracellular matrix is used as a scaffold for morphogenesis, proliferation, migration, and differentiation in tissue engineering. Extracellular matrix of natural tissues can be used as a scaffold for reconstructing biological tissues in tissue engineering. Human maxillary sinus membrane consists of cells and ECM which contain collagen, elastin, and proteoglycans. Collagen can be used as a natural scaffold via high level of biocompatibility. Materials & Methods: In this study, Human maxillary sinus membrane were decellularized by two techniques , physical method (liquid nitrogen and chemical procedures via increment concentration of sodium dodecyl sulfate (SDS in three groups. The samples were fixed with Bouin's fixator, and then were stained with Hematoxylin & Eosin. decellularised Human maxillary sinus membrane was evaluated with scanning electrone microscope.Results: Histological evaluation of decellularized scaffolds revealed that cells of the schneiderian membrane tissues were completely removed via concentration of 1% of SDS. Scanning Electrone Microscope (SEM (Leo-VP1450, Germany of the scaffolds indicated that collagen fibers of connective tissue remained intact. In 0.5 and 0.1% concentrations of SDS, few cells were observed at peripheral of ECM, so decellularization process was not complete. Conclusion: According to the results, scaffolds prepared from Human Maxillary Sinus Membrane could be used as a suitable scaffold for In vitro investigation and reconstruction and tissue engineering.

  13. Two cases with radiation-induced cancers after radiation therapy for cancer of the maxillary sinus

    International Nuclear Information System (INIS)

    We experienced 2 patients with malignant non-epithelial tumors that developed following an incubation stage of 10 years or more after radiation therapy for cancer of the maxillary sinus. In Patient 1, the primary cancer was unclear, but it was speculated that this patient had been treated for cancer of the maxillary sinus. In patient 2, cancer of the maxillary sinus had been treated in our hospital. In patient 1, the secondary cancer was a malignant histiocytoma of the parapharyngeal space. In patient 2, the secondary cancer was a spindle cell sarcoma in the maxillary sinus. According to the classification of the probability of radiation-induced cancer after treatment for malignant tumors, the probability was evaluated as A in Patient 2, and B or higher in Patient 1. In the two patients, radiation-induced cancer was strongly suggested. For treatment, extended surgery was indicated, as a rule. In Patient 1, radical neck dissection was performed. In patient 2, tumorectomy was performed several times. Concerning the prognosis, Patient 1 is alive without cancer, but Patient 2 died of intracranial invasion by tumor. The invasion of the tumor and histological type may have influenced the prognosis. The incidence of radiation-induced cancer is considered to be 1% or less. However, radiation therapy-related late disorder must be considered. (author)

  15. Associations between inflammatory cells infiltrating the ethmoid sinus mucosa, and nasal polyp size and grade of ethmoid sinus opacification on CT images in chronic sinusitis

    International Nuclear Information System (INIS)

    We investigated the types and numbers of inflammatory cells that infiltrated the ethmoid sinus mucosa in cases of chronic sinusitis in order to identify any associations with nasal polyp size and the grade of ethmoid sinus opacification on computer tomography images. The subjects were patients with chronic sinusitis who underwent endoscopic sinus surgery. Seventeen subjects also had bronchial asthma as a complication (six with aspirin-induced asthma, 11 with another form of asthma) and 24 did not have bronchial asthma as a complication (16 with allergic rhinitis, 8 with chronic sinusitis alone). The nasal polyps in the patients with bronchial asthma were significantly larger than those in the patients without bronchial asthma. Investigation of the numbers of infiltrating inflammatory cells according to polyp size revealed significantly more eosinophils as polyp size increased. In addition, infiltration of significantly more mast cells was observed when the polyps were large. Assessment of the grade of opacification of the ethmoid sinuses on computer tomography images showed a significantly higher grade of opacification in the patients with bronchial asthma than in the patients without bronchial asthma. Comparisons between the grade of opacification of the ethmoid sinuses and the number of infiltrating inflammatory cells revealed significantly more infiltrating eosinophils and mast cells in the patients with intense ethmoid sinus opacification. The above findings suggest that eosinophils and mast cells play a major role in forming the persistent inflammation of the sinus mucosa and nasal polyp tissue of patients with chronic sinusitis complicated by bronchial asthma.

    Rihani, A

    1985-01-01

    Maxillary sinusitis may be diagnosed incorrectly as TMJ pain-dysfunction syndrome because of a similarity of signs and symptoms. Both conditions can manifest with headache, facial pain radiating to the ear and the maxillary teeth, preauricular pain, and pain in the buccal vestibule posterior and superior to the maxillary tuberosity. It can be concluded that (1) more consideration should be given to sinus disturbances as a differential diagnosis in TMJ pain-dysfunction syndrome, (2) it may be preferable to refer some patients with TMJ pain to a medical center where specialists in dentistry, otolaryngology, neurology, rheumatology, and psychiatry can evaluate the patient, and (3) TMJ pain-dysfunction syndrome should be evaluated and treated by a dentist experienced in management of this disorder.

  17. Usefulness of Panoramic Radiography in the Detection of Maxillary Sinus Pathosis

    International Nuclear Information System (INIS)

    to evaluate the usefulness of the panoramic radiography, generally used in dental clinic, for the detection of the maxillary sinus pathosis due to the inflammation and tumor, through the comparison with CT findings as the absolute standard. 150 maxillary sinuses of 75 patients with or without particular signs and symptoms and showing soft tissue lesions or destruction of maxillary sinus walls in at least one sinus in CT, were selected as subject samples, and the panoramic radiography of the same patients were interpretated by 3 dental radiologists and 3 non dental radiologist given no previous information. Using the CT findings as the absolute standard, the diagnostic ability of panoraimc radiography in the mucosal thickening, maxillary sinus haziness, inferior wall destruction, medial wall destruction, posterolateral wall destruction and the superior wall destruction was evaluated using the ROC curve and the difference between dental radiologist group and non dental radiologist group was also evaluated. 1. When dental radiologist group interpretated the destruction of inferior wall and posterolateral wall, the kappa value which shows interobserver's coincidence was above 0.75.2. The diagnostic ability according to site of interpretation was the highest when the inferior wall was interpretated in both observer groups and there was a statistically significant difference between the dental radiologist group and non dental radiologist group in interpretating the mucosal thickening, haziness, destruction of the inferior and medial wall (p<0.05).3. The diagnostic ability in detecting the destruction of the sinus walls was better than in soft tissue lesions in both groups and between the groups there was a statistically significant difference (p<0.05). When detecting the destruction of inferior and posterolateral wall of the maxillary sinus there was coincident with that of CT findings, and so it is considered that diagnostic ability of panoramic radiography is high in this point. But in interpretating the destruction of medial wall and soft tissue lesions, diagnostic ability of the panoramic radiography was relatively low and there was a significant difference between the dental radiologist group and non dental radiologist group. Therefore CT or other auxiliary diagnostic method will be necessary when evaluating thorough pathosis of maxillary sinus objectively.

  18. Clinical study on the observation of unilateral shadows in the maxillary sinus

    International Nuclear Information System (INIS)

    In the everyday examination of patients exhibiting a unilateral shadow in the maxillary sinus upon imaging, the differentiation of chronic sinusitis from other diseases, including malignant tumors, is extremely important. A unilateral shadow in the maxillary sinus was detected on scout films and a subsequent CT examination of the sinus was performed in 108 patients who visited our department between January 1994 and December 1998. Bone destruction was suspected after scout films were taken in 2 patients with malignant tumors. These 2 patients account for only a small percentage of the total patient population, but account for as much as 50% of the patients with malignant tumors. In cases of malignant tumors, the CT images suggesting bone destruction agreed with operative findings. CT seems to be a useful tool for evaluating the condition of the bone. When the density of scout films and CT images were compared, no significant difference was detected, suggesting that scout films can be used for the screening of malignant tumors. The density was (+++) in both the scout films and the CT images of the 2 patients with malignant tumors. Finally, we present a flow chart for the diagnosis of unilateral maxillary sinus shadows that has been recently adopted as the basic protocol used in our department. (author)

  20. Features of inflammatory pseudotumor in the maxillary sinus on CT and MRI

    International Nuclear Information System (INIS)

    Objective: To explore the features of inflammatory pseudotumor in the maxillary sinus on CT and MRI. Methods: The CT and MRI data of 8 patients with histology-proven inflammatory pseudotumor in the maxillary sinus were retrospectively analyzed. All 8 patients underwent CT scans and 7 of them also underwent MRI examinations. In addition, the time-intensity curve (TIC) of dynamic contrast-enhanced (DCE)MR imaging were analyzed in 3 patients. Results: Two cases had lesions in the left maxillary sinus, while the others showed lesions in the right maxillary sinus. All the lesions showed irregular shape with well-defined margins in 5 cases and hazy margins in 3 cases. The mean maximum diameter of the lesions was 51 mm (ranged from 29 mm to 72 mm). On non-enhanced CT, the lesions were isodense to gray matter in 6 and slightly hypodense in 2 patients. Only 2 patients had post-contrast CT with moderate enhancement of their lesions. The lesions caused adjacent bony absorption and destruction with residual bony sclerosis. On MR T1WI, inflammatory pseudotumor showed hypointense in 2 patients and isointense in and isointense in 1 patients. Inflammatory pseudotumor showed heterogeneously slight contrast enhancement in 2 cases and moderate enhancement in 5 cases. The TIC showed a steady enhancement pattern in 4, orbit in 4, and cheek in 3 cases. Six patients underwent follow-up for 2-5 years after surgery and 2 of them were found to have recurrence. In comparison to CT, MRI was proved to show the extent of the lesions more clearly. Conclusions Bony destruction with sclerosis and hypointense signal on MR T2WI are typical manifestations of inflammatory pseudotumor in the maxillary sinus. Combined CT and MRI can provide clinicians with more comprehensive information for the diagnosis, therapy, and follow-up of these lesions. (authors)

  1. Association Between the Lateral Wall Thickness of the Maxillary Sinus and the Dental Status: Cone Beam Computed Tomography Evaluation

    International Nuclear Information System (INIS)

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

    Objectives The aim of this study is to determine the incidence, location, and orientation of maxillary sinus septa in formalin embalmed cadavers. Materials and Methods The study was conducted on 210 cadaveric heads available in our department. After taking the mid-sagittal section the specimens were opened from the medial aspect and the sinus cavity was explored for the presence of maxillary sinus septa, their anatomical plane, location and dimensions. Results The mean linear distance between maxillary sinus floor and its anatomical ostium was 26.76±5.21 mm and 26.91±4.96 mm on right and left side, respectively. A total of 59 maxillary sinus septa (28.1%) were observed in 210 maxillary specimens. Septae were most common, 33 septa (55.9%), in the middle region (between first and second molar tooth) of the sinus cavity. The maxillary sinus membrane (Schneiderian membrane) adhered tightly to the maxillary sinus and over the septae. Significantly more maxillary sinus septa were observed in edentulous maxillae in comparison to the dentate upper jaw. Conclusion Knowledge of location of maxillary sinus ostium is mandatory for the rhinologist for drainage of secretions in maxillary sinusitis. The morphological details of maxillary sinus septa, particularly their location and anatomical planes, will guide dentists in performance of safe implant surgeries. The maxillary antrum septa of category I and II may complicate the procedure of inversion of bone plate and elevation of sinus membrane during maxillary augmentation surgeries. The category III septa observed in the sagittal plane were embedded by one of the branches of the infraorbital nerve in it, and if accidentally cut will lead to infraorbital nerve palsy in maxillary sinus surgeries.

    Efficient management of chronic sinusitis remains a great challenge for primary care physicians. Unlike ENT specialists using Computed Tomography scans, they lack an affordable and safe method to accurately screen and monitor sinus diseases in primary care settings. Lack of evidence-based sinusitis management leads to frequent under-treatments and unnecessary over-treatments (i.e. antibiotics). Previously, we reported low-cost optical imaging designs for oral illumination and facial optical imaging setup. It exploits the sensitivity of NIR transmission intensity and their unique patterns to the sinus structures and presence of fluid/mucous-buildup within the sinus cavities. Using the improved NIR system, we have obtained NIR sinus images of 45 subjects with varying degrees of sinusitis symptoms. We made diagnoses of these patients based on two types of evidence: symptoms alone or NIR images along. These diagnostic results were then compared to the gold standard diagnosis using computed tomography through sensitivity and specificity analysis. Our results indicate that diagnosis of mere presence of sinusitis that is, distinguishing between healthy individuals vs. diseased individuals did not improve much when using NIR imaging compared to the diagnosis based on symptoms alone (69% in sensitivity, 75% specificity). However, use of NIR imaging improved the differential diagnosis between mild and severe diseases significantly as the sensitivity improved from 75% for using diagnosis based on symptoms alone up to 95% for using diagnosis based on NIR images. Reported results demonstrate great promise for using NIR imaging system for management of chronic sinusitis patients in primary care settings without resorting to CT.

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

    2012-08-01

    Full Text Available Abstract Background Although cone beam computed tomography (CBCT images of the maxillofacial region allow the inspection of the entire volume of the maxillary sinus (MS, identifying anatomic variations and abnormalities in the image volume, this is frequently neglected by oral radiologists when interpreting images of areas at a distance from the dentoalveolar region, such as the full anatomical aspect of the MS. The aim of this study was to investigate maxillary sinus abnormalities in asymptomatic patients by using CBCT. Methods 1113 CBCT were evaluated by two examiners and identification of abnormalities, the presence of periapical lesions and proximity to the lower sinus wall were recorded. Data were analyzed using descriptive statistics, chi-square tests and Kappa statistics. Results Abnormalities were diagnosed in 68.2% of cases (kappa = 0.83. There was a significant difference between genders (p Conclusions Abnormalities in maxillary sinus emphasizes how important it is for the dentomaxillofacial radiologist to undertake an interpretation of the whole volume of CBCT images.

  10. A comparison of Scanora radiography with Waters' and panoramic views for the detection of mucosal thickening of maxillary sinus

    International Nuclear Information System (INIS)

    The purpose of this study was to compare the diagnostic performance of Waters' and panoramic view; maxillary sinus posteroanterior and lateral scanography of Scanora for mucosal thickening of maxillary sinus as well as to identify the utility of Scanora for the detection of maxillary sinus disease. The assessment was done at 66 maxillary sinuses in 45 patients and the results were as follows: 1. Estimation of presence or absence of mucosal thickening. The sensitivity, specificity, and positive and negative predictive value of maxillary sinus posteroanterior and lateral scanography were 0.865, 0.860, 0.921, and 0.805 respectively and slightly higher than those of Waters' and panoramic views, which were 0.832, 0.835, 0.903, and 0.728 respectively. However, paired t-test showed no significant differences in the diagnostic performance of the two pairs of imaging modalities. 2. Estimation of the types of mucosal thickening. The diagnostic accuracy for type I, II, III was 75.3% on Waters' and panoramic view; 77.9% on maxillary sinus posteroanterior and lateral scanography. It was higher on the latter, but showed no significant differences from that on the former. 3. Reliability of interpretation. In intraobserver and interobserver agreement, both overall rates of agreement and kappa-value were slightly higher on maxillary sinus posteroanterior and lateral scanography than on Waters' and panoramic views. There was no significant differences between the two pairs of imaging modalities. These results suggested that scanogram is a useful diagnostic radiography as well as Waters' and panoramic view for detection of maxillary sinusitis.

    Full Text Available La perforación del suelo del seno maxilar y de las fosas nasales durante la colocación de implantes en las crestas alveolares situadas por debajo no es un hecho infrecuente. Pequeñas comunicaciones producidas durante el fresado para la preparación del lecho implantario cierran espontáneamente, pero [...] es un requisito indispensable para evitar futuras complicaciones que el implante quede estable, si no deberá ser retirado. Presentamos el caso de una mujer de 54 años de edad que acude refiriendo cacosmia y halitosis permanentes y episodios esporádicos de dolor en la zona infraorbitaria derecha asociados a rinorrea purulenta, que no ceden a la administración de distintos antibióticos. Las pruebas radiológicas muestran tres implantes dentales en el primer cuadrante sustituyendo a 1.2, 1.3 y 1.6: el primero perforando la fosa nasal, y el tercero con el extremo apical en el interior del seno maxilar derecho con una imagen radioopaca bien delimitada asociada. Confirmada la existencia de una comunicación bucosinusal de más de dos años de evolución, y establecida esta como la causa del cuadro de sinusitis maxilar crónica que la paciente padece, se determina como plan de tratamiento la extracción de los tres implantes y la reconstrucción del plano óseo mediante un injerto de hueso autólogo de mentón. Al retirar el implante en posición 1.6 se observa material de aspecto resinoso adherido a toda su superficie, con fines probablemente retentivos, y que habrá contribuido en gran medida a incrementar el proceso irritativo local. El defecto remanente es tan importante en este sector que se hace imposible anclar un injerto óseo en este área, por lo que se legra la mucosa sinusal enferma a su través, enviando muestra para su posterior análisis anatomopatológico, y se consigue el cierre primario mediante un injerto pediculado de la bola adiposa de Bichat. Los controles postoperatorios fueron favorables consiguiendo de esta forma la remisión total de la sintomatología y la recuperación completa.

It's been strongly reported that slight membrane puncture while preparing implant bed does not play a significant role in clinical outcome, as i [...] t heals spontaneously, but it is an essential requirement that the implant remains intraoperatory stable. We present the case of a 54 yr. old woman that consulted in our office referring permanent cacosmia and halitosis associated to sporadic episodes of pain and purulent rhinorrhea, that didn't ease to the administration of several different antibiotics. Radiological findings show three dental implants in the first quadrant replacing teeth 1.2, 1.3 and 1.6: first one piercing the nostril and the third one with its apical end completely into the right maxillary sinus with a delimitated radiopaque mass associated. Once confirmed the existency of an oroantral fistula and its involvement in the two-year evolution chronic sinusitis diagnosed, the treatment established included the extraction of the three implants and the simultaneous osseous reconstruction with an autologous bone chin graft. After the removal of implant 1.6, a composite resin-like material is found stuck to its surface with supposedly retentive purposes, contributing in this way in a very strong way to increase irritation. Remanent defect is so important that makes impossible bone grafting in this area, so we proceed to curette harmed sinusal mucosa, sending a sample for histological evaluation, and close with a Bichat fat pad pedicled flap. Postoperatory follow-up and evolution was favourable, achieving total remission of sympthomatology and complete recovery.

  3. Combined therapy for maxillary sinus carcinoma. The effect of prolonged treatment time on local control

    International Nuclear Information System (INIS)

    The effect of overall treatment time on the local control of maxillary sinus carcinoma was investigated. Thirty-four patients who had been treated with radiotherapy, chemotherapy and surgery from 1985 through 1996 at Hirosaki University Hospital were reviewed. Radiotherapy had been interrupted because of acute mucosal reaction or national holidays in 31 patients. The Kaplan-Meier 5-year local control (LC) rates for T2, T3, and T4 tumors and for all cases were 100%, 71.4% 58.0%, and 62.6%, respectively. Gap duration in radiotherapy (<14 days vs. ?14 days) was a significant factor in LC (80.9% vs. 41.3%, P=0.02). Overall combined treatment time (<75 days vs. ? 75 days) was a marginally significant factor in LC (72.8% vs. 49.3%, p=0.08). However, the radiation-to-surgery interval (<26 days vs. ?26 days) did not affect LC (67.2% vs. 56.9%, P=0.52). Gap duration in radiotherapy of longer than 2 weeks is a significant factor in the poor LC of maxillary sinus carcinoma in patients receiving combined therapy. Our clinical data indicate that radiotherapy for maxillary sinus carcinoma should not be interrupted for more than 2 weeks. (author)

    Full Text Available Introduction. Therapeutic approach to jaw cysts may depend on their dimensions and localization. Enucleation of cystic lesion is not always preferable in the first act, especially if large cysts are in close proximity to important anatomical structures. The aim of this paper was to present the outcome of the treatment protocol comprising preoperative decompression and subsequent enucleation of a large maxillary cyst. Case report. A 21-year-old male patient with large asymptomatic radicular cyst in the right maxillary sinus was presented to our clinic. Cone-beam computed tomography (CBCT showed a large cyst, which perforated the right anterior maxillary wall by 1.5 cm, and was in the intimate contact with the orbital floor. Surgical treatment of the cystic lesion comprised: preoperative decompression with biopsy in the first act and enucleation, performed under general anesthesia, 6 months after the observation period. Conclusion. Decompression with subsequent enucleation proved to be effective treatment of large radicular cyst in maxillary sinus with low-morbidity.

    We evaluated histologically and tomographically the effects of fresh frozen bone allograft (FFB) or bovine bone mineral (BBM) in maxillary sinus floor augmentations. In total, 30 maxillary sinuses from 30 patients (mean age = 51.17 ± 10.86 years) underwent sinus augmentation. Patients were divided in two test groups (15 sinuses each). The first group was grafted with allograft bone, and the second group received bovine bone mineral. After 6 months, bone samples from each group were collected for histological examination. Implant survival rates were 97.78% (FFB group) and 100% (BBM group) 6 months after functional loading. Median volumetric reductions of 31.2% (11.33-40.56) and 12.22% (9.91-20.59) were observed in the FFB and BBM groups, respectively. Comparisons between the groups for differences in initial and final volumes of bone (p = 0.015) and the rate of resorption (p = 0.009) showed statistically significant differences. The FFB group showed osteoblastic cells in close contact with osteoid matrix, connected through bridges between allograft bone particles and new bone formation. The BBM group showed BBM particles in close contact with new bone, with visible osteoid matrix bridges and osteoblastic cells surrounding it. None showed signs of acute or chronic inflammatory infiltrate. Despite better results with BBM, both FFB and BBM in maxillary sinus augmentation resulted in high percentages of new bone formation, and allowed implant placement with a low rate of failure of osseointegration at a 6-month follow-up.

    Full Text Available Objective To study and evaluate the method of embedding implants into crista and apophysis of sinus maxillaris precisely and safely.Methods Eight patients with insufficient alveolar bone height in the posterior maxillary region,including 5 males and 3 females with mean age of 46.4±12.8 years,received dental implant surgery.By using CT scan based on 3D reconstruction analysis,each patient was chosen in accordance with the following criteria: sinus septa and apophysis located over the lost teeth,the width at the base of the septum and apophysis was over 5mm and the included angle between sinus floor and mesial or distal slope of the septum and apophysis was less than 70°.A simulation operation was done on each patient’s rapid prototyping model and apical part of implants was set into sinus septum and apophysis.After surgical guide was fabricated,osteotomy preparation and implant placement were performed aided by the surgical guide,and then followed by immediate CT scan to thoroughly examine the relative position of implants to septum and apophysis and the integrity of the sinus membrane.Results The position of all the 8 implants was in consistent with that in the rapid prototyped model.Sinus floor was lifted to the mesial or distal surface of the septum or apophysis.One side of the implants’ apical parts,with the length ranged from 2 to 5mm,was tightly embedded to sinus septum or apophysis,and the other side of the implants was well covered by mucous membrane.The implants were found with good stability after the surgery.No damage or laceration of the sinus mucous membrane was observed.Conclusions Sinus septa and apophysis can provide the necessary height to maintain implant stability when the alveolar bone height is insufficient for the insertion of a dental implant in the posterior region.In order to precisely embed implants into sinus septum and apophysis,the following procedures are required and must strictly coordinate with one another: accurate positioning and measurement of septa and apophysis by using CT 3-dimensional reconstruction analysis and model surgery,guide aided implant placement surgery,and the use of Sinustech reamer to lift sinus floor.

    The aim of this study was to systemically assess the efficacy of platelet-rich fibrin (PRF) on maxillary sinus augmentation using the lateral approach. A PubMed search and a hand search of relevant journals and the bibliographies of selected articles were performed. Clinical studies using PRF with open maxillary sinus augmentation were included. The search provided 290 titles; only 8 studies fulfilled the inclusion criteria. Identified studies showed heterogeneity regarding surgical technique, grafting material, implant placement time, protocol, outcome measures, healing time for biopsy, and implant placement, as well as follow-up period. From the 8 identified studies, 3 studies used PRF as a sole filling material, whereas the other 5 studies used PRF with bone substitutes. PRF showed promising results as a sole filling material for sinus lift with simultaneous implant placement, and PRF seemed to accelerate maturation of a demineralized freeze dried bone allograft. Conversely, it had no effect on deproteinized bovine maturation. PRF fibrin membranes represent an easy and successful method to cover the sinus membrane or osteotomy window. PMID:25536095

    In this study, we examined the effect of uncinectomy on the alteration in local airflows and on the resulting effect on gas exchange in the maxillary sinus, by using computational fluid dynamics in two nasal cavity models: one with a preserved uncinate process, and the other with the uncinate process removed virtually. Uncinectomy distinctively changed the local flow topology by triggering the formation of counter-rotating vortices in the ostiomeatal complex, except for the instants with relatively low airflow rate when the respiration phase changed, ultimately leading to a change in the velocity field inside the ostium and maxillary sinus. Despite a significant increase in the maximum air velocity through the maxillary ostium, ventilation was found to increase only slightly when the uncinate process was removed. Furthermore, the degree of maxillary sinus ventilation by inhaled air was comparable to that by exhaled air. This was true to both models and was independent of the presence of the uncinate process.

    Full Text Available Background. The feature of malignant tumours in maxillary sinus is a late appeal of patients (T3-T4, as a result of the absence of pain and minor clinical manifestations, it requires large amounts of surgical interventions and leads to disability. Objective. The article analyzes the morphological variants of maxillary sinus squamous cell carcinoma (SCC with their immunohistochemical characteristic. Methods. In the study we analyzed the original biopsy material from 37 patients with maxillary sinus cancer T3-4N0-1M0 (31 men and 6 women aged from 37 to 71 years with histologically confirmed diagnosis of SCC for 2010-2014. The primary monoclonal antibodies CK HMW (clone AE3, p63 (clone 4A4, р16INK4 (clone DCS 240 were used. Results. Analyzing the distribution of various forms of maxillary sinus SCC, it was found that the typical forms of SCC are found in most of cases, 29 of 37 (78.4%, compared with specific morphological forms that accounted for just 21.6%. Conclusions. Due to the expression of the marker CK HMW it was found that in typical forms of SCC and in some special morphological forms (spindle cell carcinoma and verrucous carcinoma with decreasing degree of squamous cell differentiation, the level of the expression of CK HMW also decreases (p<0,001, r = 0.861; p <0,001, r = 0,638. It is an indicator of poor prognosis, but aggressive behavior of basaloid SCC and adenosquamous carcinoma do not depend on the presence or absence of CK HMW. High expression of marker p63 (average level 92,5±3,67% is a key-point of verification of basaloid SCC. Lack of positive reaction with the marker of viral lesions p16INK4 in forms with keratinization confirms the idea of different etiologic factors and ways of carcinogenesis of typical forms of SCC.

    Full Text Available The objective of this study was to determine the prevalence of concha bullosa and nasal septal deviation and their potential relationships to maxillary sinusitis. 883 CT scans taken at Creighton University School of Dentistry from 2005 to 2008 were retrospectively reviewed for the presence of concha bullosa, nasal septal deviation, and maxillary sinusitis. 67.5% of patients exhibited pneumatization of at least one concha, 19.4% of patients had a deviated septum, and 50.0% had mucosal thickening consistent with maxillary sinusitis. 49.3% of patients who had concha bullosa also had evidence of maxillary sinusitis. Only 19.5% of patients with concha bullosa also had nasal septal deviation, whereas 19.7% of patients with sinusitis also presented with nasal septal deviation. Although concha bullosa is a common occurrence in the nasal cavity, there did not appear to be a statistically significant relationship between the presence of concha bullosa or nasal septal deviation and maxillary sinusitis.

    Background Chronic sinusitis is one of the most common chronic diseases involving different age groups. Because the nature and etiology of chronic sinusitis are not completely known, there is not any standard treatment for this disease. It has been suggested that low-level laser can be used in treating chronic sinusitis but there are limited studies about its usage. In this research, intra-oral radiation of low-level laser has been described and implemented for the first time. Suggested hypotheses about the efficacy of this type of radiation (intra-oral) in treating chronic maxillary sinusitis includes this fact that the depth of maxilla’s vestibule is also the floor of maxillary sinus and sinus discharges collect in this area because of gravity effect. Therefore, with considering suitable radiation angle, this area gets the most benefits of laser’s anti-inflammatory effects. Material and Methods In this study, 20 patients with chronic maxillary sinusitis were included. They were assessed before and after treatment. Treatment plan was performed in 8 sessions every other days using low-level diode laser with 810 nm. Snot-22 questionnaire and rhinomanometry were used for evaluating patients. Changes of signs and symptoms were recorded in questionnaire every session and 6 months after treatment. Friedman and Wilcoxon tests were used for data analyses. In this study, P value laser and this improvement was statistically significant (P valuelaser is a suitable way to treat patients with chronic maxillary sinusitis. Key words:Chronic sinusitis, maxillary sinusitis, low-level laser. PMID:26644829

    A trial has been made of traditional versus antioxidant treatment of acute maxillary sinusitides. The patients were injected a mixture consisting of 4 ml emulsion of 10% dibunol liniment and 2 ml of 5% ascorbic acid made by dilution of 10 g dibunol in 30 ml sterile 0.5% novocaine solution. The mixture was introduced into the sinuses 2 times a day, in one of the study groups it was combined with 500,000 U of ampicillin in cases of purulent sinusitis. In catarrhal form the mixture was injected once a day without the antibiotic. Control groups received 4 ml dioxidine in a single dose after the sinus lavage in catarrhal sinusitis and 500,000 U ampicillin plus hydrocortisone emulsion (1 ml in 4 ml solution) 2 times a day in case of purulent sinusitis. All the patients received aevit (one capsule daily). The mean number of manipulations for the study groups were 4.4 +/- 0.4 in catarrhal sinuses and 6.3 +/- 0.5 in purulent sinusitis; in control groups, respectively, 5.9 +/- 0.5 and 10.7 +/- 0.7. Mean duration of treatment reached 5.3 +/- 0.4, 6.2 +/- 0.3 and 7.1 +/- 0.1 in the study groups and 8.5 +/- 0.2, 10.2 +/- 0.4 days in the control groups. Positive response to the treatment with antioxidants was confirmed by positive changes in blood levels of LPO products, activity of lysosomal hydrolases and antioxidant defense enzymes. The results obtained justify the inclusion of antioxidants in the schemes of acute sinusitis treatment. PMID:7785133

    This study was performed to evaluate the role Waters' view and panoramic view for the interpretation of mucosal cyst of the maxillary sinus and to determine the radiographic features of that according to the sites and sizes. For this study, clinically 25 cases of mucosal cyst of the maxillary sinus were used, and experimentally with who dry skulls, rubber ball of 15 mm in diameter for marked radiopacity, and two jelly balls of 8 and 20 mm in diameter for the similar radiopacity to cyst were used. The 25 cases with 25 panoramic views and 15 Waters' views were first analyzed, and secondly, the radiographic features of artificial lesions attached to the each wall of the antrum on Waters' view and panoramic view were analyzed. The obtained results were as follows: At clinical analysis, 1. 4 cases of 13-14 mm, 4 cases of 15-19 mm, 14 cases of 20-25 mm, 3 cases of over 30 mm in diameter were found on panoramic views. And 24 cases of 25 cases showed no relationship with teeth, and only 1 case was associated with advanced periodontal disease. 2. The majority of mucosal cysts appeared to arise the posterior portion of the floor of the sinus and were superimposed with the inominate line of zygoma and the horizontally linear image of hard palate on panoramic view. 3. Only 2 cases of 15 cases were identified on both films.At experimental analysis, 4. On Waters' view, the images of the artificial lesion of the anterior portion and midportion of the floor of the sinus were lessened in diameter compared with the real size. On panoramic views, the images of the lesion were more radiolucent with lessened diameter than images on Waters' view. 5. The images of the lesion of the posterior wall and the posterior portion of the floor of sinus on panoramic view were well detected by the preedjucated group but not or poorly detected by the non-preeducated observer group. 6. On Waters' view, both observer groups recognized that the cystic images of the posterior portion of the floor of the maxillary sinus were superimposed with the petrous portion of the skull.

    Odontoma is a mixed odontogenic hamartoma involving both epithelial and mesenchymal tissues. If left untreated, it can lead to complications in certain conditions. Here is a rare presentation of an extensive complex odontoma in maxillary sinus pushing third molar near the orbital floor causing transient diplopia in upward gaze occasionally and chronic sinusitis. Although odontomata are not uncommon and are familiar to practitioners, but some aggressive cases may cause problematic sequelae. Even postoperative complications may result if oral surgeons are not aware of the potential pitfalls associated with the surgical removal of large maxillary antrum odontomata. This article reports a rare presentation which can be considered unique because when obstruction of sinus drainage is evident, serious complications such as orbital infections, epidural and subdural empyema, meningitis, cerebritis, cavernous sinus thrombosis, brain abscess and death can occur. It also addresses points and pitfalls concerning surgery to remove odontoma. PMID:25848139

  17. Influence of postsurgical residual tumor volume on local control in radiotherapy for maxillary sinus cancer

    International Nuclear Information System (INIS)

    The aim was to study the influence of postsurgical gross residual tumor volume on local control of maxillary sinus cancer treated with radiotherapy combined with debulking surgery. Forty-three patients who underwent combined surgery and radiotherapy (50-72 Gy, median 60 Gy) for squamous cell carcinoma of the maxillary sinus were reviewed. Gross residual tumor volume (GRTV) after surgery was measured on computed tomograms obtained during the radiotherapy planning. Patients were classified according to GRTV as follows: group AA, GRTV=0 (microscopic residual, n=2); group A, GRTV 3 (n=24); group B, 10-40 cm3 (n=9); and group C, ≥40 cm3 (n=8). The relationship between local control and GRTV was analyzed using univariate and multivariate analysis. The 2-year local control rate for all patients was 62%. The differences in local control rates between groups AA, A and B were not significant (P<0.05), but the rate was significantly lower in group C than in the other groups (69% at 2 years vs 31% at 1 year, P<0.001). Multivariate analysis showed that GRTV (P=0.002) and histological differentiation (poorly differentiated histology was favorable, P=0.035) were independent prognostic factors and that intraarterial chemotherapy and administered total dose were not. Local control in groups A and B significantly depended on the total dose of radiotherapy, with 2-year control rates of patients receiving 50 Gy (n=6) and ≥60 Gy (n=27) of 17% vs 79%, respectively (P<0.001). Our data suggest that adequate, not complete, debulking associated with a total radiotherapy dose of ≥60 Gy can provide satisfactory local control for patients with squamous cell carcinoma of the maxillary sinus.

  18. Potential role of intensity-modulated radiotherapy in the treatment of tumors of the maxillary sinus

    International Nuclear Information System (INIS)

    Purpose: To assess 3-dimensional conformal radiotherapy (3D-CRT) and intensity-modulated radiotherapy (IMRT) techniques to see whether doses to critical structures could be reduced while maintaining planning target volume (PTV) coverage in patients receiving conventional radiotherapy (RT) for carcinoma of the maxillary sinus because of the risk of radiation-induced complications, particularly visual loss. Methods and Materials: Six patients who had recently received conventional RT for carcinoma of the maxillary sinus were studied. Conventional RT, 3D-CRT, and step-and-shoot IMRT plans were prepared using the same 2-field arrangement. The effect of reducing the number of segments in the IMRT beams was investigated. Results: 3D-CRT and IMRT reduced the brain and ipsilateral parotid gland doses compared with the conventional plans. IMRT reduced doses to both optic nerves; for the contralateral optic nerve, 15-segment IMRT plans delivered an average maximal dose of 56.4 Gy (range 53.9-59.3) compared with 65.7 Gy (range 65.3-65.9) and 64.2 Gy (range 61.4-65.6) for conventional RT and 3D-CRT, respectively. IMRT also gave improved PTV homogeneity and improved coverage, with an average of 8.5% (range 7.0-11.7%) of the volume receiving <95% of the prescription dose (64 Gy) compared with 14.7% (range 14.1-15.9%) and 15.1% (range 14.4-16.1%) with conventional RT and 3D-CRT, respectively. Little difference was found between the 15 and 7-segment plans, but 5 segments resulted in a reduced minimal PTV dose. Conclusions: IMRT offers significant advantages over conventional RT and 3D-CRT techniques for treatment of maxillary sinus tumors. Good results can be obtained from 7 segments per beam without compromising the PTV coverage. This number of segments is practical for implementation in a busy RT department

    Full Text Available Introduction. Hepatocellular carcinoma (HCC is the most frequent primary malignant tumor of the liver. It is usually seen in the 6th and 7th decades of life and chronic hepatitis B is the most frequent cause. Extrahepatic metastasis of HCC is an indicator of a poor prognosis and the most common sites are lungs, bones, lymph nodes, kidneys and adrenal glands. We reported a case of isolated metastasis in the right maxilla, which had been found initially, before the tumor in the liver was diagnosed. Case report. A 70-year-old man underwent dental surgery of the upper right molar. Prolonged bleeding control was difficult for up to two weeks, so the biopsy was performed. Histopathological analysis revealed a metastatic hepatocellular carcinoma. Computerized tomography (CT of the abdomen revealed a diffusely heterogeneous liver parenchyma with irregular borders and two foci of mass lesions. There were metastasis in the spleen and also two pathological retroperitoneal lymph nodes were detected, but no ascit, liver cirrhosis, cholestasis or portal vein thrombosis were seen. CT of the orbital and maxillary regions revealed a tumor mass in the right maxillary sinus, spreading to the alveolar sinus, nasal cavity and partially infratemporal space. A tumor mass was in the right orbit as well, infiltrating the surrounding bones and muscles. Clinically, there was proptosis of the right eye accompanied by amaurosis. The treatment started with chemotherapy based on 5-fluorouracil (sorafenib was not available. After three cycles, control CTs showed a stable disease in the liver, but progression in the right maxillary sinus and orbit. Enucleation of the right eye was performed and postoperative radiotherapy was planed. The patient deteriorated rapidly and died, about 6 months after the disease had been diagnosed. Conclusion. Extrahepatic metastasis of HCC represents a progressive phase of the disease with poor prognosis, so the main aim of the treatment should be palliation and care of symptoms.

  1. Preservation of the orbital contents in cancer of the maxillary sinus

    International Nuclear Information System (INIS)

    Tumor invasion of the periorbita, posterior ethmoid cells, or orbital apex is considered an absolute indication for orbital exenteration. Preservation of the orbital contents in selected cases can be applied safely to the treatment of primary maxillary sinus cancer. Patient complaints relating to the preserved eye were more commonly associated with radiation therapy than the method of reconstruction used. Reconstruction of the orbital floor with a skin graft, even when combined with radiation therapy, gave a functional eye in the majority of cases while not compromising the oncologic safety or the procedure

    International Nuclear Information System (INIS)

    Between 1985-1989 22 patients with malignant neoplasma maxillary sinus have been treated. At the first stage the surgical resection of maxilla was performed. Most of the patients (77%) had histopathological diagnosis of carcinoma planoepitheliale, 13% carcinoma solidum and 4% carcinoma adenoides cysticum. All patients had adjuvant therapy by Co-60 irradiation. Single fraction dose of 2 Gy/T 5 times a week up to total dose of 60-70 Gy/T has been applied. In the follow-up period of minimum 36 months the free-symptoms survival rate of 18%. (author)

  3. Paranasal sinuses in children: size evaluation of maxillary, sphenoid, and frontal sinuses by magnetic resonance imaging and proposal of volume index percentile curves

    International Nuclear Information System (INIS)

    Our objective was to establish the age-related 3D size of maxillary, sphenoid, and frontal sinuses. A total of 179 magnetic resonance imaging (MRI) of children under 17 years (76 females, 103 males) were included and sinuses were measured in the three axes. Maxillary sinuses measured at birth (mean±standard deviation) 7.3±2.7 mm length (or antero-posterior)/4.0±0.9 mm height (or cranio-caudal)/2.7±0.8 mm width (or transverse). At 16 years old, maxillary sinus measured 38.8±3.5 mm/36.3±6.2 mm/27.5±4.2 mm. Sphenoid sinus pneumatization starts in the third year of life after conversion from red to fatty marrow with mean values of 5.8±1.4 mm/8.0±2.3 mm/5.8±1.0 mm. Pneumatization progresses gradually to reach at 16 years 23.0±4.5 mm/22.6±5.8 mm/12.8±3.1 mm. Frontal sinuses present a wide variation in size and most of the time are not valuable with routine head MRI techniques. They are not aerated before the age of 6 years. Frontal sinuses dimensions at 16 years were 12.8±5.0 mm/21.9±8.4 mm/24.5±13.3 mm. A sinus volume index (SVI) of maxillary and sphenoid sinus was computed using a simplified ellipsoid volume formula, and a table with SVI according to age with percentile variations is proposed for easy clinical application. Percentile curves of maxillary and sphenoid sinuses are presented to provide a basis for objective determination of sinus size and volume during development. These data are applicable to other techniques such as conventional X-ray and CT scan. (orig.)

  4. A radiologic study on the experimental lesions of the maxillary sinus

    International Nuclear Information System (INIS)

    This study was performed to determine the each location of lesions in the maxillary sinus and to evaluate the relationship between the floor of the antrum and the apical regions of teeth by the comparison of the panoramic view and panoramic sinus view. For this study, experimentally with two dry skulls, jelly balls of 8 mm and 15 mm in diameter containing a short wire for the radiopacity similar to the cyst and clinically 5 patients having mucosal cyst in the antrum and 10 patients having periapical lesions of upper molars were formed by using round bur and the radiopaque periapical lesions were simulated by filling the former lesions with lead foil. Each panoramic view and each panoramic sinus view of the experimental lesions and patients were obtained by using panoramic machine and analyzed. The following results obtained; 1. On the panoramic sinus view, the innominate line was approximately coincided with the most lateral portion of the antrum and the posterior wall appeared as the narrow area at the mesial side of the innominate line. The anterior wall occupied totally the mesial side of the innominate line, and the medial wall occupied the mesial half of the antrum. 2. In all cases of experimental cystic lesion attached to each wall of the antrum, the location of each lesion was able to be determined by applying Tube shift technic. 3. The palatal root and mesiobuccal root of the molar appeared as being transposed each other mesiolaterally on the panoramic and panoramic sinus views. 4. The panoramic sinus view was superior to the panoramic view in revealing the relationship between the floor of the antrum and the periapical lesion.

  5. Long term control of a maxillary sinus mucoepidermoid carcinoma with low dose radiation therapy: a case report

    International Nuclear Information System (INIS)

    Mucoepidermoid carcinoma of the maxillary sinus is a rare malignancy of the head and neck. The location of this tumour near vital structures and its large size at presentation makes surgical resection with negative margins challenging. In incurable cases, relief from symptoms such as epistaxis may be achieved with radiation therapy. We present a case of mucoepidermoid carcinoma of the maxillary sinus that was effectively palliated with a short course of radiation therapy, achieving complete cessation of bleeding, decrease in tumour size, and long term control. We surveyed the literature on mucoepidermoid carcinomas and propose that some tumours may be particularly radiosensitive, benefiting from even short courses of radiation therapy

    We conducted prospective study comparing different methods (plain X-rays, computed tomography and ultrasonography mode-A) for the initial diagnosis of maxillary sinusitis. Twenty patients (40 maxillary sinuses) with a clinical history suggestive of sinusitis included in this study. The results were classified as abnormal or normal, using computed tomography as gold standard. The sensitivity for ultrasonography and plain X-rays was 84.6% and 69.2%, respectively. The specificity of both methods was 92.6%. This study suggests that ultrasonography can be used as a good follow-up method for patients with maxillary. sinusitis. (author)

    Full Text Available The pneumatization of the maxillary sinus often results in a lack of sufficient alveolar bone for implant placement. In the last decades, maxillary sinus lift has become a very popular procedure with predictable results. Sinus floor augmentation procedures are generally carried out using autologous bone grafts, bone substitutes, or composites of bone and bone substitutes. However, the inherent limitations associated with each of these, have directed the attention of investigators to new technologies like bone tissue engineering. Bone marrow stromal cells have been regarded as multi-potent cells residing in bone marrow. These cells can be harvested from a person, multiplied outside his body using bioengineering principles and technologies and later introduced into a tissue defect. We present a case where tissue-engineered autologous osteoblasts were used along with demineralized freeze-dried bone for sinus floor augmentation.

  10. How far can we exert organ preservation in cancer of the maxillary sinus?

    International Nuclear Information System (INIS)

    A combination of radiotherapy, chemotherapy, and surgery improved the 5-year survival rate of patients with cancer of the maxillary sinus by more than 60%. In recent years, considering the QOL of patients when they return to their former social environments, treatment methods exerting organ preservation are expected. The present study evaluated whether the combination of massive intraarterial infusion of CDDP and radiotherapy can reduce the frequency of surgical treatment for cancer of the maxillary sinus. Satisfactory results were obtained after the completion of radiotherapy (regional CR rate: 66.7%, response rate: 91.7%). Moreover, the pathohistological CR rate was 75%, and local control of the cancer was achieved by this combination therapy in 6 of 12 patients (50%) without surgical treatment. Furthermore, the 2-year cumulative survival rate was 75% when evaluated in all patients, using the Kaplan-Meier method. Although the period of investigation was short, the results of the present study suggested that the combination of massive intraarterial infusion of CDDP and radiotherapy could reduce the frequency of surgical treatment and could contribute to organ preservation in cancer therapy.

  11. Retrospective evaluation of surgical intervention following chemo- and radiotherapy of maxillary sinus cancers

    International Nuclear Information System (INIS)

    During the past 15 years, 30 patients with squamous cell carcinomas of the maxillary sinus were treated by modified partial maxillectomy following chemo- and radiotherapy, taking care to preserve facial contour and function as far as possible. Follow-up evaluation showed that local recurrences, and regional lymph node and distant metastases were more frequent in T4 patients than in T3 patients. Evaluation of the histopathological effects of preoperative chemo- and radiotherapy at the time of surgery showed that T4 patients tended to have a poorer response to the treatment than T3 patients. Analysis according to the direction of primary tumor extension showed that the incidence of local recurrence was higher in the superolateral type, whereas that of regional lymph node metastasis was higher in the medial type. The cumulative 5-year survival was high (72.2%) in Stage III patients and low (22.5%) in Stage IV patients. The overall rate was 55.4%. The treatment produced relatively good outcomes in T3 patients but poor outcomes in T4 patients. These findings indicate that T4 carcinoma of the maxillary sinus must be managed initially by a combination of irradiation and multi-chemotherapeutic drugs, and then treated by more extensive surgical resection.

    Full Text Available Introduction: Comparison of the relationships and distance between maxillary root tips and   the maxillary sinus floor using oral panoramic in the dolichocephalic and brachycephalic compared to mesocephalic individuals. Methods: Oral panoramic images from 300 individuals were analyzed and the relationships and distance between the maxillary root tips and the sinus floor was assessed by qualitative and quantitative variables. Results: The distance was significantly higher in the brachycephalic groups than that of the mesocephalic, and the mesocephalic group showed longer distance in comparison to dolichocephalic individuals. Qualitative comparison showed that type 1 relationship was the dominant position in the brachycephalic individuals while most of dolichocephalic individuals demonstrated type 2 and 3 relationships of the molar root tips and the maxillary sinus floor. Conclusion: Higher distances between the molar root tips and the maxillary sinus floor could be expected in the brachycephalic than mesocephalic and dolichocephalic individuals

  14. Clinical evaluation of multimodal treatment for squamous cell carcinoma of the maxillary sinus

    International Nuclear Information System (INIS)

    Seventy-seven patients with squamous cell carcinoma of the maxillary sinus were treated with radiotherapy and surgery (with or without intra-arterial infusion chemotherapy) from 1969 to 1986 at Tokyo Women's Medical College. The treatment given to the subjects was broadly separated into three categories: Treatment I (1969-1974), Treatment II (1975-1977), and Treatment III (1978-1986). Treatment I consisted of surgery and radiotherapy; Treatment II consisted of multimodal treatment by surgery and radiotherapy with 5-FU intra-arterial infusion chemotherapy (IAIC) from the superficial temporal artery; Treatment III consisted of surgery and radiotherapy with Adriamycin IAIC replacing 5-FU IAIC. Radiotherapy involved a total dose of 60 Gy/6 weeks in Treatment I as the standard, 50 Gy/5 weeks with 5-FU (250 mgx20 times/4 weeks) in Treatment III. Surgery by antrotomy was performed before radiotherapy and IAIC, and Denker's operation was done after radiotherapy with IAIC. The influence of patients' age, sex, T stage and N stage were examined as prognostic factors and no statistically significant differences were seen among each treatment periods. The 2-year control rate was 29% in period I, 27% in period II, and 58% in period III. The 5-year cumulative survival rate was 13% for period I, 40% for period II, and 54% for period III; the incidence of side effects during radiotherapy did not appear to increase, and the severity was at a tolerable level considering the results. However, late complications were seen in 6 cases (cataract, 5; obstinate sinusitis, 1). Thus, the study indicates that multimodal treatment using Adriamycin IAIC can minimize face deformity and allows effective function-saving treatment for carcinoma of the maxillary sinus. (author)

    Full Text Available Background and aim. Vertical and horizontal bone resorption of the alveolar ridge are common in edentul ous jaws. In the distal area of the maxilla, an adequate bone volume is often lacking because of the proximity of the sinus cavities to crestal bone. Sinus floor augmentation is an established way of increasing the height and volume of bone in the p osterior region of the maxilla, which increase the stability of dental implants. For this purpose various materials, including auto grafts, allograf ts,alloplasts, and xenografts have been used. The aim of this study was the radiographic and clinical comparison of Algipore with decalcified freeze-dried bone allograft (DFDBA inthe open maxillary sinus lift technique using piezoelectric instruments. Materials and methods. A total of 20 sinus grafts were performed in 10 patients who had a severely resorbed bilateral maxillary alveolar process with a residual bone thickness of between 1 and 5 mm (mean, 3.6 mm. The operation involved anosteotomy performed on the lateral maxillary wall using piezoelectric instruments, elevation of the sinus membrane, and placement of either of the two bone graft materials in each randomly-selected side. Preoperative and postoperative standard radiographs taken at nine months of follow- up were used to compare the outcome of bone height after the maxillary sinuslifting procedure. Changes in radiographic density after sinus grafting were evaluated using densitometry. Results. The radiographic density was 76.3% on the Algipore side and 72.4% on the DFDBA side (P >0.05. The mean height of newly formed bone in the augmented area was 12.3 mm on the Algipore side and 10.7 mm on the DFDBA side (P >0.05. Conclusion. After nine months there were no considerable clinical or radiological differences in outcome between Algipore and DFDBA and both of them were recognized as acceptable materials for sinus lift procedures

  18. Long-term prognosis of maxillary sinus malignant tumor patients treated by fast neutron radiation therapy

    International Nuclear Information System (INIS)

    From 1976 through 1990, 19 patients with maxillary sinus malignant tumor were treated with combination therapy consisting of maxillectomy and radiation of fast neutron. Fast neutron radiotherapy was performed at National Institute of Radiological Sciences. Eight patients had adenoid cystic carcinomas, three patients squamous cell carcinomas, one patient a carcinoma in pleomorphic adenoma, four patients fibrosarcomas, one patient osteosarcoma, one patient chondrosarcoma and one patient rhabdomyosarcoma. Fast neutron therapy after/before surgery was effective in fresh cases with T2-3N0M0 adenoid cystic carcinomas and sarcomas (except for fibrosarcoma). Nine patients were alive more than three years after treatment. And serious complications of fast neutron radiation therapy appeared in six of these nine patients. Visual impairment of opposite side occurred in four patients. Bone necrosis occured in one patient and brain dysfunction in one patient. (author)

  19. Comparison of pre- and postoperative radiation in the combined treatment of carcinoma of maxillary sinus

    International Nuclear Information System (INIS)

    A series of 50 patients with cancer of the maxillary sinus treated by either preoperative or postoperative radiation from February 1958 to June, 1974 is presented. In the postoperative group the patients were either free from recurrence, or if there was recurrence, the tumor was less than 0.5 cm in diameter. In the preoperative group, 23 of 36 patients survived for more than five years (64%). In the postoperative group, 4 of 14 patients survived for more than five years (26%). There is an obvious superiority in the preoperative radiation group. The surgical complication rate in the preoperative group was 29% as compared to 14% in the postoperative group. Although the incidence of complications in the preoperative group is higher, we believe it is worth attempting in clincial practice because of the more favorable survival rates

  20. Prominent response with helical tomotherapy in recurrent ameloblastic carcinoma of maxillary sinus: a case report

    International Nuclear Information System (INIS)

    Ameloblastoma is a benign but locally aggressive tumor of odontogenic epithelial tissue. Reports of radiotherapy treatment modalities are limited in the literature. A thirty-five year old male presented with complaints of headache radiating to his face for about six months and impaired vision. The patient’s Positron Emission Tomography (PET) showed a mass in the left maxillary sinus extending to the nasal cavity and invading the adjacent tissues. An R2 (macroscopic residual tumor) surgical resection performed to debulk the tumor. Due to the recurrence and residual mass, the patient was treated with helical tomotherapy. At 2 months post-radiotherapy, patient’s vision returned to normal. PET scan showed a significant reduction in lesion size 12 months post-radiation. In cases of ameloblastic carcinoma with, post-surgical recurrence or patients not suitable for surgical treatment, helical tomotherapy can be an effective treatment option

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

  3. Radiotherapy for squamous cell carcinoma of maxillary sinus. Requirements for conservative treatment strategy

    International Nuclear Information System (INIS)

    We reviewed the records of 45 patients with squamous cell carcinoma of maxillary sinus who underwent radiotherapy and intra-arterial chemotherapy with or without maxillectomy. Of 45 patients, 10 patients (stage II:III:IV A=1:5:4) were operated with radical radiotherapy without maxillectomy and had no local failure for more than 1 year (conservative and no local failure group), and 9 patients (stage III:IV A=3:6) were performed with partial or total maxillectomy after pre-operative radiotherapy and had no malignant cells in the operated specimen (group B). Complete response on radiological images was shown in 70% of patients in group A, and 67% of patients in group B. In group A, local recurrence was found in 1 of 10 patients in group A and 1 of 9 patients in group B during a further follow-up period. Five-year overall survival rate was 53% and 67% in group A and B, respectively. Five-year cause-specific survival rate was 89% and 67% in group A and B, respectively. Maxillary conservative treatment is appropriate in cases showing good response on radiological images after radiotherapy combined with concurrent intra-arterial infusion chemotherapy. (author)

  4. A 'supralethal dose phenomenon' revealed by cancer of the maxillary sinus

    International Nuclear Information System (INIS)

    In this paper a so-called ''supralethal dose phenomenon'' is reported. Two groups of patients, all of whom were carrying proved squamous cell carcinoma of the same clinical stage in their maxillary sinuses, were compared after radiotherapy in our department. The radiotherapies applied to the two groups were very similar in terms of fraction number, treatment period, dose distribution and immobilization technique, but differed in dose, i.e., 5,500 cGy for one group of 9 patients and 5,750 cGy for the other group of 20 patients. The five-year survival rates of the two groups were 8/9 and 10/20, respectively, and the difference was statistically significant (p<0.05). All patients were observed for at least five years. Except for tumor stage, the status of the patients in the two groups, including primary site of the tumor in the sinus, patients' age and cause of death for the failed cases, are also discussed in detail.

    Statement of the Problem Anatomic variations of the maxillary sinus can be detected in cone-beam computed tomography (CBCT) and may assist to locate the posterior superior alveolar artery (PSAA) and define the maxillary sinus morphology more accurately for a more strict surgical treatment plan. Purpose The study aimed to determine normal variations of the maxillary sinus with the aid of CBCT in a sample population in south of Iran. Materials and Method This cross-sectional prevalence study was based on evaluation of 198 projection data of CBCT scans of some Iranian patients aged 18-45 who referred to a private oral and maxillofacial radiology center in Shiraz from 2011 to 2013. CBCT scans were taken and analyzed with NewTom VGi device and software. The anatomic variations which were evaluated in the axial images included the presence of alveolar pneumatization, anterior pneumatization, exostosis, and hypoplasia. Moreover the location and height of sinus septa, and the location of PSAA were assessed. SPSS software (version 17.0) was used to analyze the data. Results In a total of 396 examined sinuses, maxillary sinus alveolar pneumatization was the most common anatomic variation detected. Anterior pneumatization was detected in 96 sinuses (24.2%). Antral septa were found in 180 sinuses (45.4%) and were mostly located in the anterior region. Meanwhile, PSAA was mostly detected intra-osseous in 242 sinuses (65.7%). Conclusion Anatomic variations of the maxillary sinus were common findings in CBCT of the maxilla. Preoperative imaging with CBCT seems to be very helpful for assessing the location of PSAA and the maxillary sinus morphology, which may be used to adjust the surgical treatment plan to yield more successful treatments.

    The most frequent intraoperative complication of maxillary sinus elevation procedures is the perforation of the sinus membrane, for which various protocols and grafting materials have been proposed in the literature. This article describes a novel suturing technique to close large sinus mucosa perforations. The technique is demonstrated through two clinical cases in which the sinus perforations occurred (1) in the course of a maxillary sinus elevation procedure and (2) after the removal of a cystic lesion. Bone grafting material and dental implants were placed simultaneously with the sinus repair. No infections occurred, and clinical and radiographic outcomes at 1 year postloading revealed successful implant osseointegration. PMID:25909524

    11 patients with radiodense concrements in the sinus maxillaris underwent a preoperative computertomographic examination of the sinus maxillaris and the sinus concrements. 8 patients (72.7%) with the occurrence of radiodense concrements presented postoperative a histological and microbiological infection with aspergillus fumigatus. The CT-numbers of radiodense concrements in patients with aspergillus were 2802[+-]302.4 HU (Hounsfield Unit). Concrements of patients without aspergillus infection (n=3) had lower density (368.6[+-]149.1 HU; p<0.001). The root filling materials showed narly the same CT-numbers in patients with aspergillus infection (2537[+-]398.5 HU) and in patients without aspergillus infections (2544.3[+-]460.6 HU). Density of root filling material was at the same level as density of radiopaque concrements in patients with aspergillus infections. According to CT-examinations a direct connection between root filling materials and aspergillus infection was noted. Therefore in patients with radiodense concrements computertomographic examination helps to determine the kind of sinus infection. (orig.)

    Primitive neuroectodermal tumor (PNET), which belongs to the Ewing's sarcoma (ES) family of tumors, is mainly seen in children and young adults. PNETs are extremely rare in the maxilla. Here, we report a case of PNET of the left maxillary sinus in an elderly male. Magnetic resonance imaging (MRI) revealed a slightly enhanced solid mass occupying the left maxillary sinus and infiltrating into the retroantral space. A partial maxillectomy was performed. Despite postoperative chemotherapy, follow-up computed tomography (CT) and MRI revealed a nodal metastasis in the submandibular space. Neck dissection was performed. However, the patient died 10 months after the second surgery because of distant metastasis to the liver. MRI and CT were particularly useful in detecting the extent of the tumor, recurrence, and metastasis. Further, a literature review of the previously reported PNET cases of the maxilla was carried out. In this paper, we also discuss the current approach for the diagnosis and management of these tumors.

  13. Dose escalation for maxillary sinus cancer using intensity-modulated radiation therapy (IMRT)

    International Nuclear Information System (INIS)

    Purpose: To determine the feasibility of dose escalation in radiotherapy for maxillary sinus cancer using intensity-modulated radiation therapy, and to compare the resulting dose distribution, dose-volume histogram, and TCP/NTCP data to those obtained with standard 3D conformal radiotherapy (3D-CRT) at our institution. Methods and Materials: Five cases of locally advanced or unresectable maxillary sinus cancer were selected for analysis. All patients had previously been treated with 3D conformal radiotherapy at our institution. With 3D-CRT, the prescription dose to the PTV was generally limited by the tolerance of the optic chiasm to approximately 54 Gy or slightly higher. The contralateral eye was always spared, while the ipsilateral eye was usually sacrificed. These cases were then replanned with an inverse planning algorithm developed at our institution which employs an iterative conjugate gradient search method to generate optimized intensity-modulated beams. Beam fluences were simulated using a multileaf collimator (MLC) with a 1.0 cm leaf width, or a mini-multileaf collimator (mini-MLC) with a 0.5 cm leaf width. Maximal dose escalation was attempted, again with the optic chiasm tolerance as the dose-limiting constraint. Attempts were made to spare the ipsilateral eye as well, where doing so did not preclude adequate coverage of the PTV. Dose distribution and dose-volume histogram data resulting from these attempts were then compared to those from 3D-CRT plans. TCPs and NTCPs were calculated based upon available data and compared. The effect of using a mini-MLC versus a standard MLC was also compared. Results: In all five cases, dose escalation of 5 to 10 Gy above the prescription doses allowed by 3D-CRT plans was achieved. IMRT allowed for tighter conformation of isodose lines around the PTV and away from critical normal tissues, thereby permitting this dose escalation. The improved conformality of dose distributions was further demonstrated by the following: higher V95 values (percent of volume encompassed by the 95% isodose contour) for the PTV, with equivalent NTCPs for adjacent normal tissues; less underdosing of the PTV as visualized by superimposing isodose contours on CT images; and higher TCPs. Whereas the ipsilateral eye could not be spared in any instance with 3D conformal radiotherapy, IMRT allowed for such sparing in some cases without any compromise in PTV coverage by the prescription isodose. A mini-MLC allowed for optimal precision in critical normal tissue sparing in situations where the PTV was abutting several critical structures in close proximity to each other. Conclusion: Dose escalation in radiotherapy for maxillary sinus cancer is possible with IMRT, allowing for improved target coverage by the prescription isodose as well as better conformality of dose distribution vis-a-vis adjacent critical normal tissues as compared to 3D-CRT. Use of a mini-MLC maximizes the dosimetric gains that can be achieved with IMRT for this disease

  14. Long-term results of the maxillary sinus carcinoma with irradiation and intraarterial infusion of 5-FU

    International Nuclear Information System (INIS)

    Therapeutic results of 33 primary cases of maxillary sinus carcinoma treated with irradiation and intraarterial infusion of 5-FU between 1972 and 1984 were analyzed. The 5-year crude survival rate for the group with stage T2 carcinoma (n=10) was 50.0%, and for those with T3 (n=15) and T4 (n=8) it was 46.7% and 25.0%, respectively. The overall 5-year crude survival rate was 42.4%. Eight patients who did not undergo maxillectomy survived for 5 years after irradiation and intraarterial infusion. Recurrence of the tumor after the irradiation and intraarterial infusion occurred in 63.6%, and was frequently observed at the ethmoidal region and the orbita. In the areas in which the tumor extended to regions such as the ethmoid sinus and orbita, which are nourished by arteries other than the maxillary artery, conventional intraarterial infusion was ineffective for complete tumor eradication. Therefore, in most of the patients with advanced maxillary sinus carcinoma, partial or total maxillectomy following combined therapy of intraarterial infusion and irradiation is necessary to improve a prognosis.

  15. Comparison of Results according to the treatment Method in Maxillary Sinus Carcinoma

    International Nuclear Information System (INIS)

    Purpose : A retrospective analysis was performed to investigate the proper management of maxillary sinus carcinoma. Materials and Methods : Authors analysed 33 patients of squamous cell carcinoma of maxillary sinus treated at Chonnam University Hospital from January 1986 to December 1992. There were 24 men and 9 women with median age of 55 years. According to AJCC TNM system of 1988, a patient of T2, 10 patients of T3 and 22 patients of T4 were available, respectively. Cervical lymph node metastases was observed in 5 patients(N1;4/33, N2b;1/33). Patients were classified as 3 groups according to management method. The first group, named as 'FAR' (16 patients), was consisted of preoperative intra-arterial chemotherapy with 5-fluorouracil(5-FU;mean of total dosage;3078mg) through the superficial temporal artery with concurrent radiation(mean dose delivered;3433cGy, daily 180-200cGy) and vitamin A(50,000 IU daily), and followed by total maxillectomy and postoperative radiation therapy(mean dose;2351cGy). The second group, named as 'SR'(7 patients), was consisted of total maxillectomy followed by postoperative radiation therapy(mean dose 5920 cGy). Her third group, named as 'R'(6 patients), was treated with radiation alone(mean dose;7164cGy). Kaplan-Meier product limit method was used for survival analysis and Mantel-Cox test was performed for significance of survival difference between two groups. Results : Local recurrence free survival rate in the end of 2 year was 100%, 5-% and 0% in FAR, SR and R group, respectively. Disease free survival rate in 2 years was 88.9%, 40% and 50% in Far, SR and R group, respectively. There were statistically significant difference between FAR and SR or FAR and R group in their local recurrence free, disease free and overall survival rates. But difference of each survival rate between SR and R group was not significant. Conclusion : In this study FAR group revealed better results that SR or R group. In the future prospective randomized study is in need

  16. A study on radiation therapy combined with superselective intraarterial infusion therapy for maxillary sinus carcinoma

    International Nuclear Information System (INIS)

    The data of 14 patients with squamous cell carcinoma of the maxillary sinus who were admitted to our hospital and received radiation therapy and concurrent superselective intraarterial infusion therapy between 1998 and 2008 were analyzed to determine the effect of the primary treatment and the adverse events. The subjects were between 43 and 79 years old (median, 61 years old), and there were 10 male and 4 female patients. Superselective intraarterial infusion therapy was administered using the Seldinger method, and cisplatin (CDDP) was administered by intraarterial infusion at a total of 200 mg/m2. 5-fluorouracil (FU) was systemically administered by intravenous infusion at the dose of 800 mg/m2 from day 2 to day 5. In addition, radiation therapy was given concurrently, beginning on day 2. At 4 weeks after completion of the scheduled radiation therapy combined with superselective intraarterial infusion therapy, the treatment effect was judged based on macroscopic, radiological and histopathological findings. The response rates to the primary treatment were as follows: 57.1%, complete response (CR) (8 patients) and 42.9%, partial response (PR) (6 patients). Thus, the overall response rate was 100%. As for the adverse events, while grade 4 cerebral infarction occurred in one patient, all of the other adverse events were reversible and not serious. The safety of the treatment was therefore considered to be acceptable. We are planning to investigate the long-term outcomes in a future study. (author)

  17. Treatment of advanced squamous carcinoma of the maxillary sinus by irradiation

    International Nuclear Information System (INIS)

    Between 1959 and 1972, there were 23 patients with advanced squamous carcinoma of the maxillary sinus treated by radiation therapy as the only modality. Eighteen of these patients had not shown evidence of metastasis and were locally extensive being classified as T/sub 3-4/N0M0. They received 60-75 Gy (6000-7500 rad) in 6 to 7 1/2 weeks using an anterior portal with opposed lateral wedge pairs to give a homogenous dose. No treatment was given to the neck. Of 10 patients with tumors presenting in the suprastructures, six are living 5 years with no evidence of disease (NED), one is dead of intercurrent disease, one died of metastatic disease with no evidence of tumor at the primary site, and two died of recurrent primary tumor. With suprastructure presentation, radiation therapy as a sole treatment was able to control the primary tumor in eight out of 10 patients. It is concluded that in extensive tumors of suprastructure, radiation may be the only modality required to control the primary tumor (80%). In the infrastructure, radiation has failed in 75% of the patients so that surgery may also be required as a planned part of treatment in order to control the primary tumor. Metastatic disease accounted for three of the 10 deaths as a result of tumor

    Full Text Available New fluoroquinolones like levofloxacine, with broad-spectrum of effect which is also active against anaerobic bacteria, is a prospective drug for the prevention of the inflammatory complications in implant dentistry and maxillary sinus augmentation. 34 patients have been selected for this study, including 16 women and 18 men aged 18-65. All the patients have been classified into the main and control groups. Patiens of the first group have been prescribed 500 mg of levofloxacine before and after the operation two times a day for 10 days. Patients of the control group have been treated with amocxicilline. In the control group, which has used amoxicilline, Streptococcus sanguis, Streptococcus salivarius and anaerobic bacteria have been identified. The amount of Prevotella intermedia is insignificant. The same picture has been found with Fusobacterium spp. The rate of Actinomyces spp. was insignificant over the whole period of study. Patients of the experimental group had a slightly different distribution of bacteria. On the 10th day after the operation in the main patient group no periodontal pathogenesis, which may cause inflammatory complications have been identified. During the early post-operative period no significant differences have been observed among the patients of both groups.

  19. Late injury of the eye after conformation radiotherapy for carcinoma of the maxillary sinus

    International Nuclear Information System (INIS)

    Late injury of the eye after radiotherapy for 26 patients with carcinoma of the maxillary sinus was discussed. The conformation technique, a kind of improved rotational technique, was used as the method for radiotherapy. The eyes were shielded by a tungsten- or zinc-rod during irradiation. On the healthy-sided eye, which had received a total dose of 1000-1100 rads/6 weeks (max. 1460 rads/6 weeks), no impairment of vision was seen. On the ill-sided eye given a dose of more than 6000 rads/6 weeks, severe panophthalmopathy with corneal ulceration was observed within 1 year after irradiation. Serious deterioration of visual acuity alway occurred 1.5-2 years after on irradiation of the level of 4000 rads/6 weeks. At present the weakening of visual acuity is unlikely to occur after a dose of less than 3000 rads/6 weeks to the lens. From these results it is recommended that the total dose of the eye be reduced to less than 3000 rads/6 weeks. (author)

  2. Postoperative Radiotherapy for Maxillary Sinus Cancer: Long-Term Outcomes and Toxicities of Treatment

    International Nuclear Information System (INIS)

    Purpose: To determine the effects of three changes in radiotherapy technique on the outcomes for patients irradiated postoperatively for maxillary sinus cancer. Methods and Materials: The data of 146 patients treated between 1969 and 2002 were reviewed. The patients were separated into two groups according to the date of treatment. Group 1 included 90 patients treated before 1991 and Group 2 included 56 patients treated after 1991, when the three changes were implemented. The outcomes were compared between the two groups. Results: No differences were found in the 5-year overall survival, recurrence-free survival, local control, nodal control, or distant metastasis rates between the two groups (51% vs. 62%, 51% vs. 57%, 76% vs. 70%, 82% vs. 83%, and 28% vs. 17% for Groups 1 and 2, respectively). The three changes were to increase the portals to cover the base of the skull in patients with perineural invasion, reducing their risk of local recurrence; the addition of elective neck irradiation in patients with squamous or undifferentiated histologic features, improving the nodal control, distant metastasis, and recurrence-free survival rates (64% vs. 93%, 20% vs. 3%, and 45% vs. 67%, respectively; p < 0.05 for all comparisons); and improving the dose distributions within the target volume, reducing the late Grade 3-4 complication rates (34% in Group 1 vs. 8% in Group 2, p = 0.014). Multivariate analysis revealed advancing age, the need for enucleation, and positive margins as independent predictors of worse overall survival. The need for enucleation also predicted for worse local control. Conclusion: The three changes in radiotherapy technique improved the outcomes for select patients as predicted. Despite these changes, little demonstrable overall improvement occurred in local control or survival for these patients and additional work must be done

  3. Neoadjuvant intra-arterial chemotherapy combined with radiotherapy and surgery in patients with advanced maxillary sinus cancer

    International Nuclear Information System (INIS)

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

    2014-06-01

    Full Text Available   Background and Aims: It is crucial to verify the relationship between root apices and maxillary sinus floor in some surgical procedures like extraction and implant placement or in orthodontic movements like intrusion. Protrusion of roots into the sinus increases the risk of post extraction pneumatization which in turn decreases the available bone at the implant or denture sites. The aim of this study was to determine the panoramic radiology accuracy for defining the relationship between posterior root apices and the maxillary sinus floor by Cone Beam CT (CBCT.   Materials and Methods: Paired panoramic radiographs and CBCT images of 117 subjects were examined. 452 posterior maxillary roots including second premolar, first and second molar were classified by the means of the relationship with maxillary sinus floor. CBCT was used as Gold standard method, and the agreement of panoramic findings with CBCT was examined statistically. Data were analyzed using Chi-square and Multiple logistic regressions.   Results: Agreement of the panoramic and CBCT results were seen in 57.7% of all cases. Roots which had no contacts with the sinus floor (class 0 showed a high agreement of 89.5% between two imaging techniques. Roots in contact with sinus floor (class 1 showed 58.8 % and cases with root protrusion into sinus cavity (class 3, 4 showed 50% of agreement (P<0.001. Also in 36% of cases with no protrusion into the sinus cavity (class 0, 1, 2, panoramic showed protrusion. The agreement for the premolar was higher than molars (P<0.001   Conclusion: The majority of roots which their images were projected on the sinus cavity had no vertical protrusion in CBCT cuts. Considering the results, in these cases CBCT can be recommended.

    The correction of bone defects can be performed using autogenous or alloplastic materials, such as beta-tricalcium phosphate (?-TCP). This study compared the changes in bone volume (CBV) after maxillary sinus lifting using autogenous bone (n=12), autogenous bone associated with ?-TCP 1:1 (ChronOS; DePuy Synthes, Paoli, CA, USA) (n=9), and ?-TCP alone (n=11) as grafting material, by means of cone beam computed tomography (CBCT). CBV was evaluated by comparing CBCT scans obtained in the immediate postoperative period (5-7 days) and at 6 months postoperative in each group using OsiriX software (OsiriX Foundation, Geneva, Switzerland). The results showed an average resorption of 45.7±18.6% for the autogenous bone group, 43.8±18.4% for the autogenous bone+?-TCP group, and 38.3±16.6% for the ?-TCP group. All bone substitute materials tested in this study presented satisfactory results for maxillary sinus lifting procedures regarding the maintenance of graft volume during the healing phase before the insertion of implants, as assessed by means of CBCT.

    Inflammatory injuries in the maxillary sinus may originate from root canal infections and lead to bone resorption or regeneration. This report describes the radiographic findings of 4 asymptomatic clinical cases of large reactional osteogenesis in the maxillary sinus (MS) associated with secondary root canal infection detected using cone-beam computed tomographic (CBCT) imaging. Apical periodontitis, a consequence of root canal infection, may lead to a periosteal reaction in the MS and osteogenesis seen as a radiopaque structure on imaging scans. The use of a map-reading strategy for the longitudinal and sequential slices of CBCT images may contribute to the definition of diagnoses and treatment plans. Root canal infections may lead to reactional osteogenesis in the MS. High-resolution CBCT images may reveal changes that go unnoticed when using conventional imaging. Findings may help define initial diagnoses and therapeutic plans, but only histopathology provides a definitive diagnosis. Surgical enucleation of the periapical lesion is recommended if nonsurgical root canal treatment fails to control apical periodontitis. PMID:26478436

  13. A novel approach revealing the effect of a collagenous membrane on osteoconduction in maxillary sinus floor elevation with ?-tricalcium phosphate

    EAJM Schulten

    2013-03-01

    Full Text Available Calcium phosphates are used in maxillary sinus floor elevation (MSFE procedures to increase bone height prior to dental implant placement. Whether a collagenous barrier membrane coverage of the lateral window affects bone formation within a bone substitute augmentation is currently an important matter of debate, since its benefit has not been irrefutably proven. Therefore, in this clinical study twelve patients underwent an MSFE procedure with ?-tricalcium phosphate (?-TCP. The lateral window was either left uncovered, or covered with a resorbable collagenous barrier membrane. After a 6-months healing period, bone biopsies were retrieved during implant placement. Consecutive 1 mm regions of interest of these biopsies were assessed for bone formation, resorption parameters, as well as bone architecture using histology, histomorphometry and micro-computed tomography. Comparable outcomes between the groups with and without membrane were observed regarding osteoconduction rate, bone and graft volume, osteoclast number and structural parameters of newly formed bone per region of interest. However, osteoid volume in grafted maxillary sinus floors without membrane was significantly higher than with membrane. In conclusion, our results – obtained with a novel method employed using 1 mm regions of interest – demonstrate that the clinical application of a bioresorbable collagenous barrier membrane covering the lateral window, after an MSFE procedure with ?-TCP, was not beneficial for bone regeneration and even decreased osteoid production which might lead to diminished bone formation in the long run.

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

  19. Multidisciplinary therapy consisting of minimally invasive resection, irradiation, and intra-arterial infusion of 5-fluorouracil for resectable T3/T4 maxillary sinus carcinomas

    International Nuclear Information System (INIS)

    Current goals for the treatment of maxillary sinus carcinoma include preservation of vision, eating, communication, and appearance as well as cure. 121 Japanese patients who presented with maxillary sinus carcinoma between 1979 and 2005 were analyzed retrospectively. There were 77 males and 44 females, with a median age of 63 years. All patients underwent multimodality therapy including surgery through a sublabial incision, radiotherapy, and intra-arterial chemotherapy. The regional lymph nodes were treated only in patients with neck involvement. Mean follow-up period was 79 months. The 5-year overall survival rates and local control rates were 73% and 72%, respectively. The 5-year local control rates for patients with T2 lesions were 71%; for patients with T3 lesions, 88%; and for patients with T4a lesions, 60%; and for patients with T4b lesions, 56%. In patients with squamous cell carcinoma, the 5-year local control rates were 76%. In patients with non-squamous cell carcinoma, the 5-year local control rates were 54%. There was significant difference in local control rates among these groups. Control of the primary site is important in the curative treatment of maxillary sinus carcinoma. Combined therapy with conservative surgery, radiotherapy, and regional chemotherapy is an effective method for maxillary sinus carcinoma. (author)

    The objective of the present study was to estimate the influence of isolated and combined acute suppurative Highmore maxillary sinusitis on the serum lactoferrin (LF) and interleukin-8 (IL-8) levels in the children. A total of 70 children at the age varying from 4 to 15 years were available for the examination. Twenty of them constituted the control group, 29 presented with acute suppurative Highmore maxillary sinusitis, in 21 cildren this condition was combined with frontitis, ethmoiditis, otitis, and adenoiditis. Serum lactoferrin and interleukin-8 levels were measured by solid phase enzyme-linked immunoassay. It was shown that all the aforementioned forms of rhinosinusitis were associated with a significant increase of the serum LF level, an universal factor inactivating the propagation of bacterial, viral, and fungal pathogens. The level of IL-8 known to activate chemotaxis was increased only in the children presenting with combined forms of suppurative Highmore maxillary sinusitis. It is concluded that this difference can be used for the purpose of dufferential diagnostics of different forms of suppurative maxillary sinusitis. PMID:25588485

    Full Text Available Abstract Background Functional rehabilitation of patients afflicted with severe mandibular and maxillary alveolar atrophy might be challenging especially in malformed patients. Methods Treatment planning using sinus lifting and implant placement before Le Fort I maxillary osteotomy in a patient with severe mandibular and posterior maxillary alveolar atrophy and skelettal class-III conditions due to cleft palate are described. Results A full functional and esthetic rehabilitation of the patient was achieved by a stepwise surgical approach performed through sinus lifting as the primary approach followed by implant placement and subsequent Le Fort I maxillary osteotomy to correct the maxillo-mandibular relation. Conclusion Stabilisation of the maxillary complex by a sinus lifting procedure in combination with computer aided implant placement as preorthodontic planning procedure before Le Fort I maxillary osteotomy seems to be suitable in order to allow ideal oral rehabilitation especially in malformed patients.

  3. Studies on serum protein fractions of patients with maxillary sinus cancer undergoing a combination of radiotherapy and chemotherapy

    International Nuclear Information System (INIS)

    39 cases of maxillary sinus cancer were treated with combined intra-arterial infusion of bleomycin and external irradiation of 60Coγ-ray. Serum protein fractions in the sera of 39 cases of maxillary sinus cancer were examined through the radial immunodiffusion method, 1) before radiation treatment was given, 2) at the completion of radiation therapy and 3) after radiation therapy, ranging from 1 month to 36 months. The sera obtained from patients with maxillary sinus cancer before treatment had concentrations of: α1-acid glycoprotein (α1AG), α1-antitrypsin (α1AT), α1-chymotrypsin (α1X), haptoglobin (Hp), ceruloplasmin (Cp), β1C/A glycoprotein (C3), hemopexin (Hx), IgG and of IgA which were elevated compared with those of normal controls: However, the serum concentrations of: prealbumin (Prealb), albumin (Alb), transferrin (Tf), α2-macroglobulin (α2M), HS-glycoprotein (α2HS) and of IgM were reduced significantly. At the completion of radiation therapy, the concentrations of: Prealb, Tf, α1AG, α1X, Hx, C3, IgG, IgA and of IgM rose slightly as compared with levels before radiation therapy, and the concentrations of Alb, of α2HS and of α1AT were reduced. However, there was no significant difference between the former and the latter data. In patients who died within 12 months after treatment, the Prealb, Alb, Tf, α2HS, and IgM levels examined before radiation therapy were reduced and the α1AG level was elevated compared with those who had lived more than 13 months. The Prealb, Alb, Tf, and IgM levels, after radiation therapy were reduced; while the α1AG, Hp, and α1X levels were elevated. In patients who had lived more than 13 months, after treatment, concentrations of Prealb, of Alb, of Tf, of C3, of Hx, of IgG, of IgA and of IgM rose before and after radiation therapy, compared with those who died within 12 months.

  4. Definitive radiotherapy with or without chemotherapy for T3-4N0 squamous cell carcinoma of the maxillary sinus and nasal cavity

    International Nuclear Information System (INIS)

    The objective of this study is to evaluate the efficacy and toxicity of definitive radiotherapy with or without chemotherapy for T3-4 squamous cell carcinoma of maxillary sinus and nasal cavity. Forty-two patients with T3-4N0 squamous cell carcinoma of maxillary sinus (n=30) and nasal cavity (n=12) received definitive radiotherapy. Chemotherapy was used in 34 patients and elective neck irradiation was not used. The 5-year overall survival/local control rates were 34%/29% for maxillary sinus cancer and 50%/52% for nasal cavity cancer. For maxillary sinus cancers, a performance status of Eastern Cooperative Oncology Group ≥2 (P=0.012), biologically equivalent dose <68 Gy (P=0.011) and no use of chemotherapy (P=0.037) were significant worse predictors for overall survival on log-rank analysis. Biologically equivalent dose <68 Gy was independently associated with poor local control (hazard ratio, 3.32; 95% confidence interval, 1.38-7.97; P=0.007) and overall survival (hazard ratio, 2.94; 95% confidence interval, 1.23-7.01; P=0.015). Regional recurrence occurred in only 1 of 30 patients with maxillary sinus cancer and 4 of 12 patients with nasal cavity. Two radiation necrosis in brain, one osteoradionecrosis, and one retinopathy and optic neuropathy occurred. The treatment outcome was poor and local control was a major problem. High radiation dose, effective chemotherapy and elective neck irradiation for advanced nasal cavity cancers may improve disease control. (author)

  5. Complementary role of MR imaging of ethmomaxillary sinus disease depicted at CT in cystic fibrosis

    International Nuclear Information System (INIS)

    To assess whether MR imaging can improve characterization of ethmomaxillary opacification diagnosed at CT in patients with cystic fibrosis (CF) in order to select patients that may benefit from functional endoscopic sinus surgery (FESS). Material and methods: Sixty-two CF patients (26 females and 36 males) aged 4-50 years (median 20 years) with ethmomaxillary sinus disease at CT underwent MR examination of the paranasal sinuses (coronal T1 and STIR sequences). FESS had been performed in 28 of the patients prior to this study. MR signal intensities were interpreted as mucosal thickening or infectious material, according to a previous study. Results: Three major maxillary sinus MR patterns could be distinguished: Air-filled, oval-shaped pus-filled, and streaky-shaped pus-filled sinus lumen. For air-filled maxillary sinuses with mucosal thickening, CT and MR imaging were diagnostically equivalent. Where CT showed homogeneous opacification of the maxillary sinuses, MR imaging differentiated between thickened mucosa and pus-filled areas. Patients who had undergone FESS most commonly had air-filled or streaky-shaped pus-filled maxillary sinus lumen. In non-operated patients oval-shaped pus-filled sinus lumen was most common and could occur without ethmoid disease. Conclusion: MR imaging of the paranasal sinuses can differentiate between infectious material and thickened mucosa and should be used to select CF patients with pus-filled areas that can be eradicated with FESS

    Full Text Available SUNCT syndrome (short lasting unilateral neuralgiform headache with conjuntival injection and tearing is defined as short attacks of periorbital unilateral pain and accompanied by ipsilateral lacrimation and redness of the same eye. We present an unusual SUNCT case with bilateral pain that started five years ago after an acute maxillary sinus infection that evolved to chronic sinusitis. This association has been described in few SUNCT cases, but its causal role remains uncertain. The patient was a 58 years old man that fulfilled a headache diary that showed the usual circadian pattern, worsening in the morning and afternoon, and responded to treatment with gabapentina. He was submitted to a functional endoscopic sinus surgery and evolved with milder pain. In a review of 21 patients, 5 had a past medical history of sinusitis, but the causal role of this association remained uncertain.A síndrome SUNCT (short lasting unilateral neuralgiform headache with conjuntival injection and tearing é definida como curtos ataques de dor periorbital unilateral, acompanhada de lacrimejamento e hiperemia conjuntival ipsilateral. Apresentamos um raro caso de SUNCT com dor bilateral com evolução de cinco anos e iniciado após uma infecção de seio maxilar que evoluiu para sinusite crônica. Esta associação foi descrita em poucos casos de SUNCT, porém pouco esclarecida. O paciente era um homem de 58 anos que preencheu um diário de dor que demonstrou o típico padrão circadiano da síndrome, com pioras matinais e vespertinas, e apresentou melhora com uso de gabapentina. Submetido a cirurgia endoscópica funcional em seio maxilar e evoluiu com modulação da dor, sugerindo um potencial efeito benéfico após tratamento da sinusopatia.Na revisão de literatura encontramos 21 casos de SUNCT bilateral, cinco dos quais apresentavam história de sinusite; no entanto, a relação entre as duas entidades permanece ainda incerta.

    There are numerous surgical approaches for oro-antral-fistula (OAF) closure. Secondary sinus disease is still considered by many experts a relative contra indication for primary closure. To describe a single-stage combined endoscopic sinus surgery and per-oral buccal fat pad (BFP) flap approach for large OAF causing chronic maxillary sinusitis. The records of all the patients with OAF and chronic manifestations of secondary rhinosinusitis that were treated between 2010 and 2013 in our tertiary care medical center were reviewed. The exclusion criteria were: OAF ≤ 5 mm, resolved sino-nasal disease, OAF secondary to malignancy, recurrent fistula, medical history that included radiotherapy to the maxillary bone and age local pain (n = 2, 4.4 %), persistent rhinitis (n = 2, 4.4 %) and synechia (n = 1, 2.2 %). One patient required revision surgery due to an unresolved OAF. The OAF of all the other 44 patients (97.8 %) was closed after the first procedure and the paranasal sinuses on the treated side were completely recovered. The mean follow-up time for the group was 7.6 ± 4.3 months (7-21 months), and no untoward sequelae or recurrence were reported. Combined, one step, endoscopic Maxillary sinus drainage together with per-oral BFP flap approach is an efficacious surgical approach for safe closure of OAFs that are complicated with secondary chronic maxillary sinusitis.

    Full Text Available Objectives: The purpose of the present study was to investigate the reliability of both periapical radiographs and orthopantomograms for exact detection of tooth root protrusion in the maxillary sinus by correlating the results with cone beam computed tomography.Material and methods: A database of 1400 patients scanned with cone beam computed tomography (CBCT was searched for matching periapical (PA radiographs and orthopantogram (OPG images of maxillary premolars and molars. Matching OPG images datasets of 101 patients with 628 teeth and PA radiographs datasets of 93 patients with 359 teeth were identified. Four observers assessed the relationship between the apex of tooth root and the maxillary sinus per tooth on PA radiographs, OPG and CBCT images using the following classification: root tip is in the sinus (class 1, root tip is against the sinus wall (class 2 and root tip is not in the sinus (class 3.Results: Overall correlation between OPG and CBCT images scores was 50%, 26% and 56.1% for class 1, class 2 and class 3, respectively (Cohen’s kappa [weighted] = 0.1. Overall correlation between PA radiographs and CBCT images was 75.8%, 15.8% and 56.9% for class 1, class 2 and class 3, respectively (Cohen’s kappa [weighted] = 0.24. In both the OPG images and the PA radiographs datasets, class 1 correlation was most frequently observed with the first and second molars.Conclusions: The results demonstrated that both periapical radiographs and orthopantomograms are not reliable in determination of exact relationship between the apex of tooth root and the maxillary sinus floor. Periapical radiography is slightly more reliable than orthopantomography in determining this relationship.

  9. IMRT vs. 3D Noncoplanar Treatment Plans for Maxillary Sinus Tumors: A New Tool for Quantitative Evaluation

    International Nuclear Information System (INIS)

    We compared 9-field, equispaced intensity modulated radiation therapy (IMRT), 4- to 5-field, directionally optimized IMRT, and 3-dimensional (3D) noncoplanar planning approaches for tumors of the maxillary sinus. Ten patients were planned retrospectively to compare the different treatment techniques. Prescription doses were 60 to 70 Gy. Critical structures contoured included optic nerves and chiasm, lacrimal glands, lenses, and retinas. As an aid for plan assessment, we introduced a new tool: Critical Organ Scoring Index (COSI), which allows quantitative evaluation of the tradeoffs between target coverage and critical organ sparing. This index was compared with other, commonly used conformity indices. For a reliable assessment of both tumor coverage and dose to critical organs in the different planning techniques, we introduced a 2D, graphical representation of COSI vs. conformity index (CI). Dose-volume histograms and mean, maximum, and minimum organ doses were also compared. IMRT plans delivered lower doses to ipsilateral structures, but were unable to spare them. 3D plans delivered less dose to contralateral structures, and were more homogeneous, as well. Both IMRT approaches gave similar results. In cases where choice of optimal plan was difficult, the novel 2D COSI-CI representation gave an accurate picture of the tradeoffs between target coverage and organ sparing, even in cases where other conformity indices failed. Due to their unique anatomy, maxillary sinus tumors may benefit more from a noncoplanar approach than from IMRT. The new graphical representation proposed is a quick, visual, reliable tool, which may facilitate the physician's choice of best treatment plan for a given patient

    Aim Implant rehabilitation has become a very reliable and safe procedure. However, in some cases, a small amount of bone could make implant surgery extremely difficult or even impossible. Hence, a surgical technique to augment sinus floor has been developed and improved. Nevertheless, there is still controversy over the use of a membrane over the osteotomy window. Therefore, the aim of this study was to investigate whether the use of a membrane could be beneficial in sinus floor augmentation....

    Full Text Available La rehabilitación con implantes dentales en maxila posterior es compleja debido a la presencia del seno maxilar con sus diferentes variaciones anatómicas; el objetivo de este trabajo fue determinar el volumen óseo intrasinusal necesario para realizar la instalación de uno o mas implantes dentarios sin invadir la membrana sinusal. En 22 cráneos fueron evaluados 40 senos maxilares mediante tomografías computadorizadas (TC realizando mediciones en los cortes axiales, coronales y sagitales. Se clasificaron los senos maxilares según el remanente de hueso alveolar y se instalo un implante de forma virtual en el lugar del primer molar superior, mediante el software implant view. Con estas medidas volumétricas finales se estableció las indicaciones reconstructivas intra sinusales a partir de los sitios donantes intrabucales mas frecuentemente evaluados en la literatura mundial. El grupo I (1mm a 4mm de reborde alveolar remanente presentaba déficit óseo de hasta 1,98cm3, el grupo II (4mm a 7mm presentaba déficit de 1,06cm3; el grupo III (7mm a 10mm presentaba un déficit de 0,67 cm3; a partir de estos resultados podemos concluir que los sitios intrabucales pueden ser utilizados en la mayoría de los grupo estudiados, incluyendo las reconstrucciones bilaterales.Rehabilitation with dental implants in posterior maxilla is difficult because of the presence of maxillary sinus with anatomical variations. The aim of this research was to evaluate the sinus volume to install one or more implants without invading the sinus membrane. Forty (40 maxillary sinuses were evaluated in 22 skulls by computed tomography measuring in the axial, coronal and sagittal slice. The sinus were classified according to the remaining alveolar bone and a dental implant in the place of the upper first molar was virtually installed by implant view software. With this final volumetric measurement the surgical indications were established for inlay reconstruction from intra oral donor sites frequently evaluated in world literature. Group I (1mm to 4mm of alveolar ridge showed a bone deficit of 1.98 cm3, group II (4mm to 7mm showed a deficit of 1.06 cm3; group III (7mm to 10mm showed a 0.67 cm3 deficit. In view of these results we concluded that intra oral donor site can be used for the three study groups and in some cases in bilateral reconstruction.

  12. Combined therapy with surgery, radiation and chemotherapy for T3-T4 squamous cell carcinoma of maxillary sinus. National Cancer Center Hospital East experience

    International Nuclear Information System (INIS)

    Since 1960's, many institutes treated carcinoma of maxillary sinus with combined therapy: surgery, radiation, and intra-arterial infusion chemotherapy in Japan. On the other hands, surgery followed by radiation or chemoradiation is the standard option of treatment for sinonasal carcinoma in western countries. This study reports the NCCHE's 14-year experience with maxillary squamous cell cancer, treated with surgical resection followed by radiation, or trimodal combination therapy. Eighty-seven previously untreated, T3-T4 status patients with squamous cell carcinoma of maxillary sinus underwent treatment at our division. During the average follow-up period of 85.9 months, the 5-year overall survival and local control rate were 47.3% and 60%, respectively. The 5-year overall survival among the patients had T3 and T4a tumor were 59.0% and 51.6%. However, all patients with T4b tumor died, their median survival time was 9.1 months. Almost all patients had T3 and T4b were treated with trimodal therapy, a third patient of T4a status underwent treatment with surgery followed by radiation. There was no difference in overall survival according to treatment in T4a patients. We should consider the other approach for treatment, like superselective high-dose cisplatin infusion with concomitant radiotherapy in patients with advanced cancer of maxillary sinus in future.

    Full Text Available La perforación del suelo del seno maxilar y de las fosas nasales durante la colocación de implantes en las crestas alveolares situadas por debajo no es un hecho infrecuente. Pequeñas comunicaciones producidas durante el fresado para la preparación del lecho implantario cierran espontáneamente, pero es un requisito indispensable para evitar futuras complicaciones que el implante quede estable, si no deberá ser retirado. Presentamos el caso de una mujer de 54 años de edad que acude refiriendo cacosmia y halitosis permanentes y episodios esporádicos de dolor en la zona infraorbitaria derecha asociados a rinorrea purulenta, que no ceden a la administración de distintos antibióticos. Las pruebas radiológicas muestran tres implantes dentales en el primer cuadrante sustituyendo a 1.2, 1.3 y 1.6: el primero perforando la fosa nasal, y el tercero con el extremo apical en el interior del seno maxilar derecho con una imagen radioopaca bien delimitada asociada. Confirmada la existencia de una comunicación bucosinusal de más de dos años de evolución, y establecida esta como la causa del cuadro de sinusitis maxilar crónica que la paciente padece, se determina como plan de tratamiento la extracción de los tres implantes y la reconstrucción del plano óseo mediante un injerto de hueso autólogo de mentón. Al retirar el implante en posición 1.6 se observa material de aspecto resinoso adherido a toda su superficie, con fines probablemente retentivos, y que habrá contribuido en gran medida a incrementar el proceso irritativo local. El defecto remanente es tan importante en este sector que se hace imposible anclar un injerto óseo en este área, por lo que se legra la mucosa sinusal enferma a su través, enviando muestra para su posterior análisis anatomopatológico, y se consigue el cierre primario mediante un injerto pediculado de la bola adiposa de Bichat. Los controles postoperatorios fueron favorables consiguiendo de esta forma la remisión total de la sintomatología y la recuperación completa.Perforation of the floor of the maxillary sinus or nasal cavity during implant placement in the residual bone located below is not an infrequent situation. It's been strongly reported that slight membrane puncture while preparing implant bed does not play a significant role in clinical outcome, as it heals spontaneously, but it is an essential requirement that the implant remains intraoperatory stable. We present the case of a 54 yr. old woman that consulted in our office referring permanent cacosmia and halitosis associated to sporadic episodes of pain and purulent rhinorrhea, that didn't ease to the administration of several different antibiotics. Radiological findings show three dental implants in the first quadrant replacing teeth 1.2, 1.3 and 1.6: first one piercing the nostril and the third one with its apical end completely into the right maxillary sinus with a delimitated radiopaque mass associated. Once confirmed the existency of an oroantral fistula and its involvement in the two-year evolution chronic sinusitis diagnosed, the treatment established included the extraction of the three implants and the simultaneous osseous reconstruction with an autologous bone chin graft. After the removal of implant 1.6, a composite resin-like material is found stuck to its surface with supposedly retentive purposes, contributing in this way in a very strong way to increase irritation. Remanent defect is so important that makes impossible bone grafting in this area, so we proceed to curette harmed sinusal mucosa, sending a sample for histological evaluation, and close with a Bichat fat pad pedicled flap. Postoperatory follow-up and evolution was favourable, achieving total remission of sympthomatology and complete recovery.

    Deitmer, T; Scheffler, R

    1990-04-01

    To investigate the pathogenesis of swimmer's sinusitis, a group of 20 swimmers and 20 controls were interviewed and examined. Clinical examination was followed by rhinomanometry, sonography of the maxillary sinuses, a saccharin test to assess mucociliary transport in the nose, and a viable cytological sampling of the nasal mucosa. Anamnesis showed a preponderance of symptoms of sinusitis and chronic rhinitis in the swimmer group, as well as a reddening of the nasal mucosa and a swelling of the adenoids. Sonography showed mucosal thickening in the antrum in more cases among the swimmers. Rhinomanometry, the saccharin test, and viable cytological sampling revealed no significant differences between the groups. It is argued that pathogenesis is more probable through cooling of the skin of the face and the whole body than through entrance of water into the upper respiratory tract. PMID:2354017

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

    Neurilemmoma is a benign tumor of the nerve sheath that arises on cranial and spinal nerve roots as well as along the course of peripheral nerves. A case of a neurilemmoma that arose in the left infratemporal fossa of a 29- year-old male was presented. Plain radiographs, enhanced computed tomography scan, and magnetic resonance imaging demonstrated a large, well-circumscribed, heterogeneously enhanced mass with extension into the pterygopalatine fossa. Displaced by the large mass, bowing-in of the posterior maxillary antral wall was noted and a provisional diagnosis of a benign soft tissue tumor was made. The mass was completely excised and a diagnosis of neurilemmoma was confirmed.

  1. Effect of LCD monitor type and observer experience on diagnostic performance in soft-copy interpretations of the maxillary sinus on panoramic radiographs

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the effect of liquid crystal display (LCD) monitor type and observer experience on the diagnostic performance in soft-copy interpretations of maxillary sinus inflammatory lesions on panoramic radiographs. Ninety maxillary sinuses on panoramic images were grouped into negative and positive groups according to the presence of inflammatory lesions, using CT for confirmation. Monochrome and color LCDs were used. Six observers participated and ROC analysis was performed to evaluate the diagnostic performance. The reading time, fatigue score, and inter-/intra-observer agreements were assessed. The interpretation of maxillary sinus inflammatory lesions was affected by the LCD monitor type used and by the experience of the observer. The reading time was not significantly different, however the fatigue score was significantly different between two LCD monitors. Inter-observer agreement was relatively good in experienced observers, while the intra-observer agreement for all observers was good with monochrome LCD but not with color LCD. The less experienced observers showed lowered diagnostic ability with a general color LCD.

  4. Radiographic evaluation of the maxillary sinus prior to dental implant therapy: A comparison between two dimensional and three dimensional radiographic imaging

    International Nuclear Information System (INIS)

    This study was performed to evaluate the diagnostic efficacy of panoramic radiography and cone-beam computed tomography (CBCT) in detecting sinus pathology. This study was based on a retrospective evaluation of patients who had undergone both a panoramic radiograph and a CBCT exam. A total of 100 maxillary sinuses were evaluated. Four examiners with various levels of expertise evaluated the images using a five-point scoring system. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic efficacy of the two modalities. The image analysis was repeated twice, with at least two weeks between the evaluation sessions. Interobserver reliability was assessed using Cronbach's alpha, and intraobserver reliability was assessed using Cohen's kappa. Maxillary sinus pathology was detected in 72% of the patients. High interobserver and intraobserver reliability were observed for both imaging modalities and among the four examiners. Statistical analyses using ROC curves demonstrated that the CBCT images had a larger area under the curve (0.940) than the panoramic radiographs (0.579). Three-dimensional evaluation of the sinus with CBCT was significantly more reliable in detecting pathology than panoramic imaging

    2008-01-01

    Full Text Available Sarcomatoid carcinomas are rare tumors. These tumors have been reported at other sites, but head and neck origin is extremely uncommon. We report here a rare case of sarcomatoid carcinoma involving the maxilla. Only four such cases with maxillary origin have been discussed in English literature earlier. As compared to squamous cell carcinoma of maxilla, this variant is associated with poor prognosis and advanced disease at presentation, as was also seen in our case. There are no standard recommendations for management owing to the rarity of this histology. Surgery and radiotherapy form the mainstays of treatment. Exploration of the role of chemotherapy and novel targeted therapy agents is warranted in order to improve treatment results.

  7. Orthovoltage radiation therapy treatment planning using Monte Carlo simulation: treatment of neuroendocrine carcinoma of the maxillary sinus

    International Nuclear Information System (INIS)

    Dose distributions that result from treating a patient with orthovoltage beams are best determined with a treatment planning system that uses the Monte Carlo method, and such systems are not readily available. In the present work, the Monte Carlo method was used to develop a computer code for determining absorbed dose distributions in orthovoltage radiation therapy. The code was used in planning treatment of a patient with a neuroendocrine carcinoma of the maxillary sinus. Two lateral high-energy photon beams supplemented by an anterior orthovoltage photon beam were utilized in the treatment plan. For the clinical case and radiation beams considered, a reasonably uniform dose distribution (±10%) is achieved within the target volume, while the dose to the lens of each eye is 4-8% of the prescribed dose. Therefore, an orthovoltage photon beam, when properly filtered and optimally combined with megavoltage beams, can be effective in the treatment of cancers below the skin, providing that accurate treatment planning is carried out to establish with accuracy and precision the doses to critical structures.

  8. Squamous cell carcinoma of the maxillary sinus and the oral part of the upper jaw. Comparison of treatment results

    International Nuclear Information System (INIS)

    The treatment results were compared in 77 patients with maxillary sinus squamous cell carcinoma (MC) and 53 patients with squamous cell carcinoma arising from the oral part of the upper law (OC). Both sets of patients received radiotherapy alone, or radiotherapy combined with surgery and/or chemotherapy. Computerized tomography was useful for the definition of the treatment volume. Intraarterial chemotherapy was given in 89 of 130 patients and in these patients the total radiation dose was reduced by about 10 Gy. No difference was found in the 5-year survival rate between the MC (65%) and the OC (66%) groups. The cumulative incidence of local failure was higher in MC (36%) than in OC (26%), whereas the ultimate incidence of neck node metastasis was higher in OC (43%) than in MC patients (18%). Half of the inoperable patients (9/18) were older than 80 years and had contraindications to anaesthesia and major surgery. The local recurrence rate was high in the inoperable MC patients (6/8). Contralateral simus cancers occurred in 4 patients in the MC group. (orig.)

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

    Full Text Available La mala calidad del hueso, reabsorciones extremas y la presencia de la cavidad del seno maxilar constituían obstáculos insalvables para la rehabilitación implanto-soportada en el sector posterior del maxilar atrófico. La elevación de seno es probablemente la primera opción de tratamiento en el paciente tributario de rehabilitación con implantes en ese sector. El uso de implantes cortos (menos de 10 mm se ha asociado tradicionalmente con unas tasas de supervivencia menores que la de los implantes largos. No obstante la aparición de nuevas superficies y diseños indican que este tipo de implantes puede soportar de forma fiable restauraciones dentales. Presentamos la técnica de instalación de implantes de superficie porosa sinterizada, asi como una revisión actualizada sobre el comportamiento de los implantes cortos.Poor bone quality, extreme bony resorption and a pneumatized mqxillary sinus are a severe Challenger for reconstruction of the atrophic edentuous posterior maxilla. Sinus lift is probably the gold standard for Management of that area. Short implants (<10mm have traditionally been associated with lower survival rates. The introduction of new surfaces and designs indicate that this type of implants can adequately support dental restorations. We present the technique of installation of sinterised porous dental implants together with an update on the behaviour of short implants.

    There are no available detailed data on the three-dimensional courses of the human superior alveolar nerves and vessels. This study aimed to clarify the relationships of the maxillary sinus with the superior alveolar nerves and vessels using cone-beam computed tomography (CT) combined with μ-CT and histological analyses. Digital imaging and communication in medicine data obtained from the scanned heads/maxillae of cadavers used for undergraduate/postgraduate dissection practice and skulls using cone-beam CT were reconstructed into three-dimensional (3D) images using software. The 3D images were compared with μ-CT images and histological sections. Cone-beam CT clarified the relationships of the maxillary sinus with the superior alveolar canals/grooves. The main anterior superior alveolar canal/groove ran anteriorly through the upper part of the sinus and terminated at the bottom of the nasal cavity near the piriform aperture. The main middle alveolar canal ran downward from the upper part of the sinus to ultimately join the anterior one. The main posterior alveolar canal ran through the lateral lower part of the sinus and communicated with the anterior one. Histological analyses demonstrated the existence of nerves and vessels in these canals/grooves, and the quantities of these structures varied across each canal/groove. Furthermore, the superior dental nerve plexus exhibited a network that was located horizontally to the occlusal plane, although these nerve plexuses appeared to be the vertical network that is described in most textbooks. In conclusion, cone-beam CT is suggested to be a useful method for clarifying the superior alveolar canals/grooves including the nerves and vessels.

    We treated a 65 year-old man with severe facial pain after extended maxillectomy due to carcinoma of maxillar sinus. He had been suffering from pain at rest, on mastication, or at treatment of surgical wound. Various kinds of analgesics had been tried, but his pain did not disappear. At 17 weeks after the operation, he came to our pain clinic. Because his pain was thought to be due to reflex sympathetic dystrophy (RSD), stellate ganglion blocks (SGB) were performed. After 5 administrations of SGB, pain was reduced markedly but the pain at treatment of wound persisted. We thought that persistent pain would need trigeminal nerve block. Then Gasserian ganglion block was performed directly through an open wound after the operation. After the Gasserian ganglion block, the pain was diminished remarkably. He could tolerate procedures for facial prosthesis. Pain control after the operation in this patient was very efficient to improve his quality of life. Serum concentrations of catecholamines, serotonin and substance P were measured. The levels of norepinephrine and serotonin are related to the mechanism of pain as seen in this patient. PMID:8865730

  14. Superselective intra-arterial chemotherapy (SIC) by using the Seldinger technique as the treatment strategy for maxillary sinus carcinoma

    International Nuclear Information System (INIS)

    We have been applying superselective intra-arterial chemotherapy (SIC) by using the Seldinger technique as the treatment strategy for maxillary sinus carcinoma since 1998 in combination with radiotherapy and surgery. SIC allows delivery of high-dose anticancer drugs to the target tumor at high concentrations through its feeding vessel with few adverse effects by neutralizing and limiting the toxic effects of cisplatin (CDDP) within an acceptable range. We studied the effect of primary treatment and adverse events in 40 patients with squamous cell carcinoma of the maxillary sinus who underwent high-dose SIC combined with radiotherapy in our department between 1998 and 2008. The patients were 30 men and 10 women aged 43 to 75 years (median, 61 years). All carcinomas were advanced and graded as T3 in 17, T4 in 23, and N+ in 8. Some of the carcinomas reached the skull base or extended deep into the orbit. SIC was performed using the Seldinger technique from the femoral artery. Total CDDP dose was 200-300 mg/m2 (mean, 210 mg/m2). All vessels used for the treatment were those branching from the external carotid arteries; those from internal carotid arteries were not used for intra-arterial infusion. Following arterial infusion chemotherapy, systemic administration of 800 mg 5-fluorouracil (FU) was started on Day 2. Simultaneous radiotherapy was started on Day 2 at a dose of 2 Gy with a goal of increasing up to 60 Gy. Patients enrolled in this treatment arm received two courses of chemotherapy at 1- to 2-week intervals, along with a total dose of 60 Gy of radiotherapy from 1998 to 2007. Since 2008, two courses of SIC with the Seldinger technique, based on the results of postoperative pathological examination, and curative radiation at 60 Gy became the preferred basic treatment strategy irrespective of tumor size, and evaluation of treatment response at the level of 40 Gy was abandoned. For residual or recurrent carcinoma, we took a ''wait and see'' approach and conducted salvage operation as additional treatment. Adverse events of chemotherapy and SIC combined with radiotherapy were completed as scheduled. The treatment response was evaluated at 1 month based on macroscopic, imaging, and histopathological findings. In total, the Seldinger technique was performed 73 times in 40 patients. The mean number of feeding vessels used for treatment was 2.3. Follow-up of adverse events revealed Grade 3 or higher stomatitis in 45% of patients; although it often led to anorexia or dysphagia, it was reversible in all cases. Five patients needed granulocyte-colony stimulating factor (G-CSF) administration for leukocytopenia. Grade 3 or higher renal dysfunction related to CDDP administration was observed in 6 patients. Three patients underwent hemodialysis for Grade 4 renal dysfunction and all could discontinue hemodialysis. All adverse events were reversible and non-serious except for 3 patients with suspected symptoms of transient cerebral ischemia. Primary treatment response was complete response (CR) in 50.0% and partial response (PR) in 25.0% at 40 Gy, with a response rate of 75.0%. Thirty patients received surgery after intra-arterial chemotherapy. Of these, 10 patients rated as CR before surgery were all pathological CR. Of 10 patients who achieved PR in their primary treatment response after SIC combined with radiotherapy, 5 patients were pathological CR in the postoperative pathological evaluation. The final CR rate was 62.5%. These results suggest that adverse events of this therapy are relatively minor and within an acceptable range. In terms of local control, SIC may avoid invasive surgical procedures. (author)

    Full Text Available La pérdida de dientes superiores causa reabsorción del proceso alveolar y la neumatización del seno maxilar. La implantología oral ha permitido solucionar la perdida de dientes, sin embargo, cuando existe neumatización del seno maxilar, la disponibilidad ósea se ve disminuida, dificultando el procedimiento implantologico. Para remediar esta situación se efectúa la técnica quirúrgica de levantamiento del piso del seno maxilar, la que puede tener complicaciones por la morfología interna del seno, específicamente por la presencia de septos intrasinusales. El objetivo de este estudio es verificar la presencia y distribución de los septos intrasinusales, debido a su importancia en técnicas quirúrgicas realizadas en implantología oral. Se realizó un estudio descriptivo, basado en el análisis visual de huesos maxilares aislados. De 65 huesos se seleccionaron 51(42 dentados y 9 edéntulos que cumplían con determinados criterios de inclusión. La segunda parte del estudio consistió en dividir topográficamente el piso del seno en tres regiones: anterior a la cresta cigomato alveolar, en relación a ella, y posterior a la cresta. La observación de los septos fue realizado por un único examinador, asistido por un dispositivo USB, con 4 leds de alta luminiscencia. De los 51 maxilares analizados se obtuvo: 74,5%, presentaron al menos un septo intrasinusal, 25,4%, no presentaron septos visibles. Los maxilares que presentaron un único tabique correspondieron al 33,3% de la muestra, el 19,6 % de la muestra presento sólo dos tabiques, el 15,7% presentó tres tabiques, mientras que los maxilares que presentaron más de tres tabiques intrasinusales correspondieron sólo al 5,9%. Del total de tabiques encontrados (75 tabiques el 42% se observó en la región anterior, 21% en la región de la cresta cigomato alveolar y el 37 % en la región posterior del seno maxilar. De los 42 maxilares en condición dentada el 88,1% presento tabiques intrasinusales, mientras que del total de los maxilares edéntulos (9 solo el 11% presento tabiques intrasinusales. Este estudio establece que un porcentaje importante de los huesos maxilares poseen septos intrasinusales que modifican la morfología del piso sinusal con una frecuencia y ubicación variable. Esta situación deberá ser considerada y evaluada mediante imagenología en la realización de técnicas quirúrgicas de elevación del piso del seno maxilar.The loss of upper teeth causes alveolar process resorption and maxilary sinus pneumatization. Oral implantology has solved these losses, however, when pneumatization of the maxillary sinus exists, bone availability is diminished, difficulting implantology procedure. To remedy this situation, the surgical technique of lifting the maxillary sinus floor is indicated, which can have complications because of the internal maxillary sinus morphology, specifically the presence of intrasinusal septa. The aim of this study is to verify the presence and distribution of intrasinusal septa, due to its importance in surgical techniques performed in oral implantology. We conducted a descriptive study, based on visual analysis of isolated maxilary bones. Of 65 bones, 51 (42 dentate and 9 edentulouswere selected that met certain inclusion criteria. The second part of the study was, to divide the sinus floor topographically into three regions: anterior to the zygomatic alveolar crest, in relation to it, and posterior to the crest. The observation of the septa was performed by a single examiner, assisted by a USB device with 4 high-luminance LEDs. Of the 51 maxillary analyzed obtained: 74.5% had at least one intrasinusal septum, 25.4% showed no visible septa. The maxilary bones that had a single septum corresponded to 33.3% of the sample, 19.6% of the sample had only two septa, 15.7% had three septa, while the maxillary bones that had more than three intrasinusal septa corresponded only to 5.9%. Of all septa found (75 septa 42% was observed in the anterior region, 21% in the region of the zygomatic crest and 37% in the posterior region of the maxillary sinus. Of the 42 dentate maxillary bones in 88,1% present intrasinusal septa, while the total edentulous maxillary bones (9 only 11% present intrasinusal septa. This study establishes that a significant portion of the maxillary bones have intrasinusal septa that modify the morphology of the sinus floor with a variable frequency and location. This situation must be considered and evaluated by imaging techniques in case of performing surgical elevation of the maxillary sinus floor.

  16. CT and MRI findings in mucoceles of paranasal sinuses and their diagnostic value

    International Nuclear Information System (INIS)

    Objective: To study the CT and MRI findings of mucoceles of paranasal sinuses and their value in differential diagnosis between mucoceles and tumors. Methods: Twenty-two cases including 37 mucoceles were studied. CT was performed in all and MRI was performed in 10 cases. CT and MRI findings were analysed and correlated with operative findings. Results: Of 37 mucoceles, 19 were found in ethmoid sinuses, 9 in frontal sinuses, 5 in sphenoid sinuses and 4 in maxillary sinuses. Sinus expansion and thinning of sinus walls were found in all 37 sinuses with mucoceles on CT. Bony defect in sinus wall was found in 24 sinuses resulting in protrusion of the mucoceles into adjacent structures. CT showed low density with respect to muscle in 26 sinuses, identical density in 6 sinuses and high density in 5 sinuses and peripheral sinus mucosa enhancement in 7 cases. On MRI, the mucocele contents exhibited various signal intensities on T1- and T2-weighted images according to the protein concentration. Eight cases who underwent contrast study showed peripheral mucosa enhancement. Conclusions: CT and MRI can accurately display the location and characteristic findings of mucoceles and play an important role in diagnosis and differential diagnosis

  17. Studies on serum protein fractions of patients with maxillary sinus cancer undergoing a combination of radiotherapy and chemotherapy. 2. Relationship between changes in serum protein fractions and prognosis

    International Nuclear Information System (INIS)

    We examined the correlations between changes in serum protein fractions and the prognosis of the patients. The levels of 21 protein components of the sera of 36 patients with maxillary sinus cancer were determined by a single radial immunodiffusion method before and after radiation therapy. The patients with maxillary sinus cancer were treated with combined intra-arterial infusion of bleomycin and external irradiation of 60 Co gamma-rays, and were concurrently treated with 5-fluorouracil at 200 mg/day p.o. The levels of the same protein components were also measured in 34 normal adult as a control. All patients were observed 5 years and 12 years after radiation therapy. In patients who had survived at least 5 years after radiation therapy, the Alb, Tf, Hx, IgG and IgM levels measured before radiation therapy were elevated significantly compared with those who had died within 5 years. In those who had survived at least 5 years, the Alb, Tf, Hx, IgG, IgM, IgA and IαI levels measured after radiation therapy were elevated significantly compared with those who had died within 5 years, and AT III was reduced. In cases of maxillary sinus cancer following a period of 5 to 12 years after radiation therapy, multiple regression analysis was used to determine whether increased concentrations of serum protein fractions were associated with good prognosis for the original disease. α2HS, IgM, HX, α1AT and α1X before radiation therapy were positively correlated with survival, whereas AT III, Pmg, Cp, IgA, and α1AG showed negative correlations. After radiation therapy, Pmg, Hx, Cp, Cl inh and Fib were found to be positive factors of survival rate, whereas α2M, α2PI, IαI, IgA, α1AG and C3 were negative factors. (author). 54 refs

RESULTADOS: Nove pacientes tiveram extensão tumoral para a bochecha, oito para o espaço mastigador, sete para o assoalho da boca e palato duro, cinco para a fossa pterigóide, cinco para a órbita, três para o etmóide e um para a base do crânio. Três pacientes foram classificados como T3 e sete, como T4. Dois tinham metástases linfonodais no momento da apresentação inicial, os quais pertenciam ao estágio T4. Todos os casos foram confirmados com exame histopatológico. CONCLUSÃO: A análise precisa da extensão local e disseminação tumoral fornecida pela tomografia computadorizada e ressonância magnética desempenha papel importante no planejamento cirúrgico, influenciando, também, na conduta terapêutica e prognóstico.OBJECTIVE: To evaluate the role, especially of computed tomography, in the staging of maxillary sinus carcinomas. MATERIALS AND METHODS: Ten cases of carcinoma treated in Hospital Heliópolis Department of Diagnostic Imaging and Head and Neck Surgery, São Paulo, SP, Brazil, in the period between 1988 and 2002, were evaluated. RESULTS: Nine patients presented with tumor extension to the cheek, eight to the masticator space, seven to the mouth floor and hard palate, five to the pterygoid fossa, five to the orbit, three to the ethmoid bone, and one to the skull base. Three of the patients were staged T3, and seven T4. Two patients had lymph nodes metastases at their initial presentation, and were staged T4. All of the cases were histopathologically confirmed. CONCLUSION: The accurate analysis of the tumor local extent and dissemination by means of computed tomography and magnetic resonance imaging plays a relevant role in the surgical planning, besides influencing the therapeutic conduct and prognosis.

  19. Salvage surgery for local recurrence after concomitant radiotherapy and superselective arterial infusion of cisplatin in patients with squamous cell carcinoma cancer of the maxillary sinus

    International Nuclear Information System (INIS)

    This retrospective study aimed to assess the role of salvage surgery for local recurrence after concomitant radiotherapy and superselective arterial infusion of cisplatin (RADPLAT) in patients with squamous cell carcinoma cancer of the maxillary sinus as an initial treatment. Forty-one patients were treated by RADPLAT between 1999 and 2009. Local recurrence in the primary site was observed in 12 patients of whom 9 could undergo further salvage surgery. Primary disease control was achieved in 7 of these patients (successful salvage rate, 58.3%). Successful salvage rates for T3, T4a and T4b primary disease were 66.7% (2/3), 66.7% (4/6) and 33.3% (1/3), respectively. The 5-year overall survival rate was 73.6% in all patients. Severe postoperative complication was seen in one patient. Prognosis of patients with locally recurring maxillary sinus squamous cell carcinoma after RADPLAT is relatively good. This is because residual/recurrent tumor was located in anterior portion of the face in most cases. This result should be taken into consideration when the initial treatment plan is decided and the choice of salvage surgery for such recurrent cases should be carefully determined. (author)

    This systematic review evaluated the effect on bone formation and implant survival of combining platelet-rich plasma (PRP) with bone grafts in maxillary augmentation. A comprehensive review of articles listed in the PubMed/MEDLINE, Embase, and Cochrane Library databases covering the period January 2000 to January 2015 was performed. The meta-analysis was based on bone formation for which the mean difference (MD, in millimetres) was calculated. Implant survival was assessed as a dichotomous outcome and evaluated using the risk ratio (RR) with 95% confidence interval (CI). The search identified 3303 references. After inclusion and exclusion criteria were applied, 17 studies were selected for qualitative analysis and 13 for quantitative analysis. A total of 369 patients (mean age 51.67 years) and 621 maxillary sinus augmentations were evaluated. After the data analysis, additional analyses were performed of the implant stability quotient, marginal bone loss, and alveolar bone height measured by MD. The results showed no significant difference in implant stability (P=0.32, MD 1.00, 95% CI -0.98 to 2.98), marginal bone loss (P=0.31, MD 0.06, 95% CI -0.05 to 0.16), alveolar bone height (P=0.10, MD -0.72, 95% CI -1.59 to 0.14), implant survival (P=0.22, RR 1.95, 95% CI 0.67-5.69), or bone formation (P=0.81, MD -0.63, 95% CI -5.91 to 4.65). In conclusion, the meta-analysis indicates no influence of PRP with bone graft on bone formation and implant survival in maxillary sinus augmentation. PMID:26775635

    The objective of this study was to assess the effects of maxillary sinus floor elevation with a tissue-engineered bone constructed with bone marrow stromal cells (bMSCs) and calcium-magnesium phosphate cement (CMPC) material. The calcium (Ca), magnesium (Mg), and phosphorus (P) ions released from calcium phosphate cement (CPC), magnesium phosphate cement (MPC), and CMPC were detected by inductively coupled plasma atomic emission spectroscopy (ICP-AES), and the proliferation and osteogenic differentiation of bMSCs seeded on CPC, MPC, and CMPC or cultured in CPC, MPC, and CMPC extracts were measured by MTT analysis, alkaline phosphatase (ALP) activity assay, alizarin red mineralization assay, and real-time PCR analysis of the osteogenic genes ALP and osteocalcin (OCN). Finally, bMSCs were combined with CPC, MPC, and CMPC and used for maxillary sinus floor elevation in rabbits, while CPC, MPC, or CMPC without cells served as control groups. The new bone formation in each group was detected by histological finding and fluorochrome labeling at weeks 2 and 8 after surgical operation. It was observed that the Ca ion concentrations of the CMPC and CPC scaffolds was significantly higher than that of the MPC scaffold, while the Mg ions concentration of CMPC and MPC was significantly higher than that of CPC. The bMSCs seeded on CMPC and MPC or cultured in their extracts proliferated more quickly than the cells seeded on CPC or cultured in its extract, respectively. The osteogenic differentiation of bMSCs seeded on CMPC and CPC or cultured in the corresponding extracts was significantly enhanced compared to that of bMSCs seeded on MPC or cultured in its extract; however, there was no significant difference between CMPC and CPC. As for maxillary sinus floor elevation in vivo, CMPC could promote more new bone formation and mineralization compared to CPC and MPC, while the addition of bMSCs could further enhance its new bone formation ability significantly. Our data suggest that CMPC possesses moderate biodegradability and excellent osteoconductivity, which may be attributed to its Ca and Mg ion composition, and the tissue-engineered bone constructed of CMPC and bMSCs might be a potential alterative graft for maxillofacial bone regeneration.

We present the case of a 33 year old male, that consulted for nasal obstruction, maxillary enlargement and left exophthalmos of 2 years of evolution. Contrast enhanced computed tomography showed a hypódense mass with a ring enhanced lesion in the left maxilla, extending to the nasal cavity, with orbital floor and anterior wall of the maxillary sinus destruction. A biopsy sample was informed as cavernous hemangioma. Accordingly, it was treated by supraselective arterial embolization and sclerotherapy previous to surgical resection. A subtotal maxillectomy was performed following the Weber-Ferguson approach, with no recidives after a 15 month follow-up. In addition, we compare our findings and patient management with those reviewed in the literature.

  6. Diagnosis of drowning using post-mortem computed tomography based on the volume and density of fluid accumulation in the maxillary and sphenoid sinuses

    International Nuclear Information System (INIS)

    Recent studies have reported that drowning victims frequently have fluid accumulation in the paranasal sinuses, most notably the maxillary and sphenoid sinuses. However, in our previous study, many non-drowning victims also had fluid accumulation in the sinuses. Therefore, we evaluated the qualitative difference in fluid accumulation between drowning and non-drowning cases in the present study. Thirty-eight drowning and 73 non-drowning cases were investigated retrospectively. The fluid volume and density of each case were calculated using a DICOM workstation. The drowning cases were compared with the non-drowning cases using the Mann–Whitney U-test because the data showed non-normal distribution. The median fluid volume was 1.82 (range 0.02–11.7) ml in the drowning cases and 0.49 (0.03–8.7) ml in the non-drowning cases, and the median fluid density was 22 (?14 to 66) and 39 (?65 to 77) HU, respectively. Both volume and density differed significantly between the drowning and non-drowning cases (p = 0.001, p = 0.0007). Regarding cut-off levels in the ROC analysis, the points on the ROC curve closest (0, 1) were 1.03 ml (sensitivity 68%, specificity 68%, PPV 53%, NPV 81%) and 27.5 HU (61%, 70%, 51%, 77%). The Youden indices were 1.03 ml and 37.8 HU (84%, 51%, 47%, 86%). When the cut-off level was set at 1.03 ml and 27.5 HU, the sensitivity was 42%, specificity 45%, PPV 29% and NPV 60%. When the cut-off level was set at 1.03 ml and 37.8 HU, sensitivity was 58%, specificity 32%, PPV 31% and NPV 59%

    Objective: To correlate the features of inflammatory changes in the paranasal sinuses on magnetic resonance imaging (MRI) with computed tomography (CT). Methods and patients: One hundred and fourteen patients with histologically proven nasopharyngeal carcinoma (NPC) were staged with both CT and MRI. All CT and MRI images of patients with mucosal thickening but no tumour involvement of the sinuses were retrospectively analysed. Results: There were inflammatory changes in 36 maxillary, 21 sphenoid and 16 ethmoid sinuses. These changes include mucosal thickening, retention cysts, retained secretions, inspissated secretions and dystrophic calcification. MRI is superior to CT in separating thickened mucosa, retained secretions and retentions cysts. Conclusion: It is important to appreciate CT changes of sinusitis and the corresponding spectrum of MRI features. (Copyright (c) 1998 Elsevier Science B.V., Amsterdam. All rights reserved.)

    Chronic rhinosinusitis (CRS) is a common inflammatory condition of nasal and paranasal sinus mucosa. Although pathogenic bacteria were postulated as main etiological factor responsible for most cases of CRS, the involvement of molds was recently proved in some cases. The aim of the study was to conduct mycological analysis of material obtained from patients operated on due to chronic sinusitis. The study included 107 patients, 45 women and 62 men. During the surgery, a fragment of mucosa from the region of the ethmoid bulla was obtained as microbiological characteristics of this material closely resemble those of sinus mucosa. In addition, maxillary sinus lavage was obtained. The control group comprised patients without chronic sinusitis. The dithiothreitol solution method was used for the lavage examination. The tissue material (mucosal fragment from the region of the ethmoid bulla) was incubated in 2% liquid Sabouraud medium for 24 h. The material was inoculated onto culture media. The presence of molds was detected in 67% of examined samples. Overall, 41 species belonging to 12 genera were isolated. The most frequently detected genera included Penicillium spp. (46%) and Aspergillus spp. (16%). In addition, Cladosporium spp. (11%), Fusarium spp. (7%), Acremonium spp. (4%), Eurotium spp. (4%), Alternaria spp. (2%), Chaetomium spp. (1%), Geotrichum spp. (1%), Verticillium spp. (1%), Rhizopus spp. (1%), and some unidentified colonies (5%) were isolated. Penicillium crustosum, Penicillium citrinum, Aspergillus niger, Cladosporium cladosporioides, and Fusarium verticillioides were the most prevalent species. PMID:24121778

    The purpose of this study was to assess the current status in Japan of the treatment for squamous cell carcinoma of the T4 maxillary sinus (MS-SCC) and its use to plan clinical trials in the future. The data for 128 patients with previously untreated MS-SCC were obtained from 28 institutions from 2006 to 2007. Of the 128 patients, 118 patients with curative intent were included in an analysis of the treatment and its results. Of the 118 patients, 73 patients had T4a disease, and 45 with T4b. Thirty-nine patients (33.1%) were treated with total maxillectomy, 25 (21.2%) with partial maxillectomy, 22 patients (18.6%) with RADPLAT, 19 patients (16.1%) with IV-CRT, and 13 patients (11.0%) with others. The 5-year overall survival rate and local control rate for 118 patients were 49.8% and 48.9%, respectively. The 5-year overall survival rates for patients with T4aN0M0 and T4bN0M0 were 67.5% and 29.8%, respectively. This study was retrospective, but we could understand the tendency of treatment choice and treatment results. It will be useful information to plan clinical trials in the future. (author)

    A young female complained repeated nasal discharge for over three months with discomfort of right cheek, and oral antibiotics had less effect. She has a history of "root canal therapy" five years before. Physical examination found purulent secretion in the right middle nasal meatus, and light tenderness in the right side of the maxillary sinus area. The CT scan of paranasal sinus shown possible fungal infection of right maxillary sinus. Finally the nasal endoscopic surgery confirmed the fungus ball of right maxillary sinus with foreign body (the root canal filling material). PMID:26685411

    This report assesses the results following sinus floor augmentation performed 14 years previously in which bovine bone xenograft material was used without implant insertion. After sinus floor augmentation, using a 20:80 mixture of autogenous bone and inorganic bovine bone material (Bio-Oss), bone biopsy specimens were taken from the grafted site, processed with Donath's sawing and grinding technique, stained with toluidine blue, and mounted on high-sensitivity plates for histology and microradiography. Histologic and microradiographic analysis showed the ingrowth of newly formed bone into the graft with interspersed residual Bio-Oss granules. The percentage of Bio- Oss and newly formed bone was 10.18% and 9.32%, respectively, within a total surface area of 70.61 mm² at the site of the corresponding missing first molar, and the percentage of Bio-Oss and newly formed bone was 11.47% and 14.96%, respectively, within a total surface area of 63.92 mm² at the corresponding missing second molar. The newly formed bone was vital without signs of resorption. This study produced strong evidence that newly formed bone was distributed throughout the bone substitute material around all of its granules and that the grafted site consisted of vital bone even in its central parts. The differences in degradation rate and/or whether the effect of bone graft substitutes alone and/ or in combination with other types, shapes, and sizes of graft materials needs further clinical investigation, especially in regard to long-term changes.

    Full Text Available Introducción. Los cordales ectópicos son aquellos incluidos en posiciones inusuales o desplazados a distancia de su normal localización anatómica. La erupción ectópica de un diente dentro de la cavidad oral es común pero en otros lugares es raro. La erupción ectópica puede ir asociada con alteraciones en el desarrollo, procesos patológicos o yatrogenia. Caso Clínico. Mujer de 56 años de edad con tercer molar superior derecho ectópico a nivel de región infraorbitaria-seno maxilar. Presentaba dolor e inflamación hemifacial derecha de larga evolución y resistente a tratamiento médico. Se realizó exéresis quirúrgica de dicho cordal mediante abordaje de Caldwell-Luc. Discusión. En muchos casos la etiología de un cordal ectópico no puede ser identificada. La mayor parte de las veces son asintomáticos y diagnosticados mediante estudios radiológicos. Conclusión. La indicación de la exodoncia en el caso de un diente ectópico en general viene determinada por la presencia de sintomatología o en prevención de futuras complicaciones.Introduction. Ectopic third molar teeth are those that are impacted in unusual positions, or that have been displaced and are at a distance from their normal anatomic location. Ectopic eruption of a tooth within the oral cavity is common, but rare in other sites. Ectopic eruption can be associated with developmental disturbances, pathologic processes or iatrogenic activity. Case Report. Female, fifty-six years old, with an upper right ectopic third molar located in the maxillary sinus-infraorbital region. She presented with pain and inflammation of the right side of her face that she had been experiencing for along time and which had been resistant to treatment. Surgical excision was carried out of the third molar tooth using the Caldwell-Luc approach. Discussion. In many cases the etiology of ectopic third molars cannot be identified. Generally they are asymptomatic and diagnosed by radiology studies. Conclusion. The indication for extraction in ectopic teeth cases is in general determined by the presence of symptomatology, or by the need for preventing future complications.

  20. Radiological changes in the paranasal sinuses in lepromatous leprosy

    International Nuclear Information System (INIS)

    In view of the high incidence of nasal involvement in lepromatous leprosy and the production of a highly infectious discharge from the nasal mucosa, it seemed pertinent to investigate the paranasal sinuses whose lining greatly increase the surface area of mucous membrane in the upper respiratory tract. Sinus radiographs were taken of 16 patients diagnosed, clinically and bacteriologically, as having lepromatous leprosy with nasal involvement. All 16 patients showed radiological abnormalities which are summarized. The most constant finding was mucosal thickening of the maxillary antra. The significance of these results is discussed. Sinus X-rays, while not diagnostic for leprosy may give additional information to both the leprologist and the ENT surgeon. (author)

The mass was well circumscribed and showed solid enhancement on contrast-enhanced CT. Histological examination of the mass was consistent with oncocytic schneiderian papilloma. It is of prime importance to recognize that a sinonasal lesion with intense hypermetabolism on {sup 18}F-FDG PET/CT does not necessarily signify malignancy. Oncocytic schneiderian papilloma should be included in the differential diagnosis of an intensely hypermetabolic and solidly enhancing mass of the nasal cavities or paranasal sinuses.

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

  10. Radiodiagnostics of maxillary osteomyelitis

    International Nuclear Information System (INIS)

    Osteomyelitis is defined as an inflammation or infection in bone tissues - cancellous bone, bone marrow, bone compacta and periosteum due to invasion of infection from surrounding tissues. Maxillary osteomyelitis is less common disease than osteomyelitis of mandible. This can be explained by anatomical structure of maxilla which is mainly composed of sinuses and thin bone lamellae. Such a structure allows rapid propagation of the infection to the surface. There have been examined and treated 70 patients with osteomyelitis of facial bones within past 15 years at Department of stomatology and maxillo-facial surgery of P.J. Safarik University in Kosice. Only four cases were diagnosed as maxillary osteomyelitis. The aim of this study was to mention the differences in anatomy and symptoms of acute and chronic stage of maxillary osteomyelitis and to give a detailed radiographic picture of this affliction.

    Full Text Available Sinoliths are very rare calculi found particularly in maxillary , frontal and ethmoid sinuses. Sinolith present in the maxillary antrum is also called as antrolith. The origin of the nidus of calcification may be extrinsic (foreign body in sinus or intrinsic (stagnant mucus and fungal ball. Most antroliths are small and asymptomatic. Larger ones m ay present as sinusitis with symptoms like pain and discharge. An antrolith causing only epistaxis without associated sinusitis is very rare. We report a case of 55 yr. old male who came with h/o epistaxis. On evaluation the CT shows the presence of antrol ith in the left maxillary sinus.Caldwell - luc operation was done and the antrolith was removed. We report this case because of its rarity.

    A case of primary extracranial meningioma of the maxillary antrum is reported. A 45-year-old male presented with symptoms of chronic sinusitis. Imaging studies showed a soft tissue mass with calcification, filling the maxillary antrum. The mass was removed surgically, and pathological studies revealed a ribroblastic meningioma. The maxillary antrum is an uncommon location of primary extracranial meningioma, and our case is the sixth to be reported in that location.

  13. Change of reactive small round cell infiltration in the stroma after pre-operative 8 Gy irradiation using treatment to maxillary sinus carcinoma with Kitasato method and prognosis according to the change

    International Nuclear Information System (INIS)

    In this paper, we report the results of studying the degree of reactive small round cell infiltration in the stroma as a prognostic indicator of maxillary sinus carcinoma treated with the Kitasato method and the effect of preoperative irradiation at 8 Gy on infiltration in the stroma. Out of 74 patients who had been treated with this method in the 27 years from 1976 to 2002, the following patients were enrolled in this study: 17 patients from whom tissue specimens could be obtained with biopsies or probe antrotomies before preoperative irradiation, and 40 patients from whom tissue specimens could be obtained after preoperative irradiation including those who survived five years and who died of a specific cause. We classified the pattern of distribution of small round cell infiltration in the stroma into three degrees. Stromal infiltration was compared before and after the operation to recognize the prognosis for each patient based on the pattern of distribution of small round cell infiltration in the stroma. The correlation between the degree of stromal infiltration and prognosis was studied statistically. Both the patients with increased stromal infiltration and those postoperatively preserving a preoperative score of 2+ with irradiation at 8 Gy had a good prognosis. The five-year survival rate for patients was significantly higher in those with a score of 2+ for their tissue specimens. The Kitasato treatment method is effective and improves the quality of life (QOL) of patients with maxillary sinus carcinoma. The prognosis was good in the patients with increased or preserved stromal infiltration. The low-dose irradiation and chemotherapy used in combination seemed to be biological response modifiers.

    A 2-year-old Quarter Horse gelding was examined for torticollis, facial protuberances over the frontal and maxillary sinuses, and persistent nasal discharge unresponsive to antibiotics. Radiograph revealed an osseous mass in the right paranasal sinuses. Histologic examination of the biopsied mass led to a diagnosis of osteoma. The mass was removed surgically in sections from the right frontal and maxillary sinuses through separate bone flaps, and sinuses were irrigated with saline solution for 8 days after surgery. Two weeks after surgery, radiography revealed small osseous opacities in the right paranasal sinuses. These opacities remained unchanged in radiographs obtained up to 23 months after surgery

  16. Normal value of mucosal thickness of paranasal sinuses, as seen on brain MRI

    International Nuclear Information System (INIS)

    To evaluate incidentally observed thickened mucosa of paranasal sinuses on brain MRI of patients without evidence of sinusitis. We reviewed brain MRI of 82 adults aged over 20; 45 were males and 37 were females. Brain axial MRI was obtained from the hard palate with 8mm thickness and 2mm gap. The mucosal thickness of incidentally observed paranasal sinuses seen on brain MRI was measured at the mostly thickened portion by T2- and T1-weighted images. The mean mucosal thickness at the most thickened portion of paranasal sinuses, regardless of their location was 3.5mm with S.D. of 1.5mm. The mucosal thickening was observed more commonly in maxillary (79 patients, mean 3.0mm, S.D. 1.4mm) and ethmoid sinuses (80 patients, mean 2.7mm, S.D. 1.1mm) than in sphenoid (39 patients, mean 1.6mm, S.D. 1.4mm) or frontal sinuses (38 patients, mean 1.9mm, S.D. 1.4mm). Mucosal thickening of up to 6.5mm was a common finding on brain MRI of patients without evidence of sinusitis; accuracy was 95%

  20. Bony anatomic variants of the paranasal sinuses and nasal septum. Comparison between normal and chronic sinusitis

    International Nuclear Information System (INIS)

    Agger nasi cells, concha bullosa, Haller's cells and deviation of the nasal septum were evaluated with coronal plane computerized tomographic (CT) scanning in patients with normal paranasal sinuses (44 cases) and patients with chronic sinusitis (91 cases). Agger nasi cells were present in 68 (50.4%) of cases. Concha bullosa was present in 39 cases (28.9%), Haller's cells were present in 15 cases (11.1%), and deviation of the nasal septum was present in 64 cases (47.4%). Haller's cells were more commonly encountered in cases with normal paranasal sinuses (20.5%), than in cases with chronic sinusitis (6.6%). Other bony structural variations were noted at a similar frequency in both groups. Each sinus (frontal sinus, ethmoid sinus, maxillary sinus and sphenoid sinus) of patients with chronic sinusitis was then evaluated separately. Agger nasi cells were observed more frequently in chronic frontal sinusitis and ethmoid sinusitis compared to subjects with normal sinuses. Concha bullosa was observed more frequently in cases with normal frontal sinuses and ethmoid sinuses than in cases of chronic frontal sinusitis and ethmoid sinusitis. Haller's cells and deviation of the nasal septum were observed at a similar frequency in both groups. Based on these results, it was thought that these bony structural variations sometimes disturbed the reopening of the normal ventilation and drainage pathways of the paranasal sinuses at the stage of acute sinusitis. These nasal ventilatory disturbances may predispose the patient to recurrent sinusitis, and may finally result in chronic sinusitis. (author)

    Full Text Available Introdução: Quando a altura do osso alveolar residual é insuficiente na região posterior da maxila, a elevação do assoalho do seio maxilar visando a viabilizar a instalação de implantes dentários é um procedimento indicado. O enxerto autógeno (EA) de regiões intra ou extraorais é considerado o padr [...] ão ouro para esse procedimento. Novas opções de substitutos ósseos vêm surgindo, como o Straumann(r) BoneCeramic (BC) - 60% constituído de hidroxiapatita e 40% de ? tricálcio fosfato, 100% sintético -, sendo o material utilizado no presente trabalho. Objetivo: Avaliar e comparar histologicamente o comportamento deste substituto ósseo com o enxerto ósseo autógeno. Material e método: Dez pacientes saudáveis e parcialmente desdentados na região posterior da maxila foram submetidos à elevação do assoalho do seio maxilar previamente à instalação de implantes dentários osseointegráveis, sendo, destes, cinco com EA e cinco com BC. Após seis meses do tempo de integração do enxerto ósseo, as amostras foram coletadas por uma trefina e coradas em hematoxilina e eosina para microscopia. Resultado: Todos os implantes osseointegráveis apresentaram boa estabilidade primária. A análise histológica demonstrou tecido ósseo neoformado viável em quatro das cinco amostras do BC, além de um íntimo contato do tecido ósseo mineralizado recém-formado com as partículas do BC. Em uma amostra do BC, não foi observada formação de osso viável. O tecido ósseo formado a partir do EA e do BC apresentou uma característica histológica similar. Conclusão: O BC se mostrou um material adequado para a elevação do assoalho do seio maxilar previamente à instalação de implantes dentários osseointegráveis. Abstract in english Introduction: Sinus lift to permit insertion of implants when alveolar residual bone height is insufficient may be considered an effective procedure. The use of autogenous bone from intraoral or extraoral sources is considered as the gold standard for this procedure. New options of bone substitutes [...] have been emphasizing, such as Straumann(r) BoneCeramic (BC), consisting of 60% of hydroxyapatite and 40% of calcium phosphate, 100% synthetic material that was used in this work. Objective: This investigation was designed to evaluate and compare the behavior of a fully synthetic biphasic calcium phosphate (BCP) 60% hydroxyapatite and 40% of ?-tricalcium phosphate (Straumann(r) Bone-Ceramic) to the autogenous bone graft (ABG) in maxillary sinus floor elevation procedure prior to installation dental implants. Material and method: Ten healthy patients who were partially edentulous in the posterior maxilla were included in this study and submitted to a unilateral maxillary sinus floor elevation procedure, with grafting using either ABG (control group; 5 patients) or BCP (test group; 5 patients). After 6 months of healing implant sites were created and biopsies taken for histological analyses. Result: A primary stability was achieved with all dental implants after the biopsies. Histological investigation showed a viable new bone tissue formed in 4 of 5 BCP specimens. Also, showed close contact between new bone and BCP particles, in 4 of 5 specimens. In 1 of 5 BCP specimens no viable bone tissue was found. Both ABG and BCP produced similar amounts of newly formed bone, with similar histologic appearance. Conclusion: The results indicate that BCP is a suitable material for sinus augmentation for the placement of dental implants.

  3. Normal development of paranasal sinuses in children: A CT study

    International Nuclear Information System (INIS)

    To evaluate the normal development of the paranasal sinuses in children with CT, authors prospectively studied with brain CT scans of 260 children without known sinus disease, ranging image from 7 days to 16 years. Maximal anteroposterior and transverse diameters(mm) and maximal cross- sectional area(mm2) of both sides of the maxillary sinus were measured with the aid of computer device. As to the ethmoidal and spheroidal sinuses, we simply documented the presence of the aplastic ethmoidal sinus and calculated the age-incidence of the spheroidal sinus pneumatization, respectively.There noted three phases in the development of the maxillary sinus. The anteroposterior and transverse diameters of the maxillary sinus increased nearly in parallel. The former was always greater than the latter. In no cases was the edathamil sinus aplastic and almost all sinuses were pneumatized even in infants as early as 7 old days. CT identified the conchal pattern of sphenoidal sinus pneumatization infants as early as 11 days old. Sphenoidal sinus pneumatization was seen in 38% of the children under the age of 1 year, 82% of the children between the age of 1 and 2 years, and almost all children older than 2 years. The anteroposterior and transverse diameters of the maxillary sinus seem to reach the adult size by 8 years of age, and the conchal pattern of sphemoidal sinus pneumatization can be recognized earlier with CT than on the plain radiographs

    The possibilities of imaging reparative osteogenesis in 26 patients after osteoplasty on paranasal sinuses were studied. At the end of the first week after operation, in 3 mos, 6 mos, 9 mos, 12 mos scintigraphy with 99mTc-pyrophosphate (pyrphotech) was carried out to all the patients. The degree of radiopharmaceutical accumulation in the site of transplantation permitted to judge about the course of osteogenesis, to determine its intensity in different periods after operation. It is shown that osteoscintigraphy with 99mTc-pyrophosphate (pyrotech) is an objective method of reparative osteogenesis diagnosis and has a high precision

    Background Sinus fungus ball, an accumulation of fungal dense concretions, is a common disease in practice, and might cause fatal complications or lead to death once converted into invasive type. Early preoperative diagnosis of this disease can lead to appropriate treatment for patients and prevent multiple surgical procedures. Up to now, the diagnostic criteria of sinus fungus ball have been defined and computed tomography (CT) scan was considered as a valuable preoperative diagnostic tool. However, the sensitivity of clinical CT is only about 62%. Thus, investigating the factors which influence sensitivity is necessary for clinical CT to be a more valuable preoperative diagnosis tool. Furthermore, CT scan usually presents micro-calcifications or spots with metallic density in sinus fungus ball. Previous literatures show that there are some metallic elements such as calcium and zinc in fungus ball, and they concluded that endodontic treatment has a strong correlation with the development of maxillary sinus fungus ball and zinc ion was an exogenous risk factor. But the pathogenesis of sinus fungus ball still remains unclear because fungus ball can also develop in other non-maxillary sinuses or the maxillary sinus without root canal treatment. Is zinc ion the endogenous factor? Study on this point might be also helpful for investigating the pathogenesis of sinus fungus ball. In this paper, we tried to investigate the factors which influence the sensitivity of clinical CT by imaging sinus fungus ball with microCT. The origin of zinc ion was also studied through elements test for different fungal ball samples using x-ray fluorescence technique. Methods Specimens including fungal ball material and sinus mucosa from patients confirmed by pathological findings were extracted after surgery. All fungal ball specimens came from sphenoid sinus, ethmoidal sinus and maxillary sinus with or without previous endodontic treatment respectively. All of them were imaged by microCT with spatial resolution up to 5μm to acquire three-dimensional structure, and then the heavy metal elements were detected with x-ray fluorescence spectrometer analysis. Result High concentration of zinc and calcium were detected in all fungal ball specimens compared to sinus mucosa membrane. Particles with different size varied from disperse to density, which have similar shape to the result of clinical CT but with different size, were found in three-dimensional reconstruction results of microCT. Conclusions Spatial resolution is an influent factor of clinical CT sensitivity for sinus fungus ball. Improving the resolution of clinical CT will help to improve its sensitivity. Besides iatrogenic endodontic materials, endogenous metal elements of zinc and calcium might associate with the growth of fungal ball and the micro-calcifications or spots with metallic density of CT imaging.

    The present study compares the behaviour of an anorganic bone matrix material and a synthetic ?-Tricalcium phosphate employed as grafting materials in a sinus floor augmentation two step protocol in humans. In order to estimate the initial occupation level for the two materials, an ‘in vitro’ simulation has been performed to analyse macroporosity created due to particle packing in terms of porosity and interparticle distances. Grafting in the sinus floor augmentation was performed by filling the defects only with pure grafting materials without autogenous bone addition. The new-bone generated is 100% based on the osteoconductive properties of the grafted materials in contact with physiological fluids. The implants were placed 8 months after the grafting procedure. All the implanted positions were biopsied and embedded in methacrylate resin. Histomorphometric analyses were done over thin film undecalcified sections. Packing simulations allow establishing a comparison of the resorbed volumes related to the initial occupancy of the grafting materials inside the defect. The nature of this interconnected pore network is very alike for either material so new-bone generated was similar (~35 vol.%). PMID:21625341

    The influence of the maxillary sinuses in acoustic rhinometry (AR) has not been evaluated, and this is the aim of the present study. We examined six subjects with AR and magnetic resonance imaging (MRI) after nasal decongestion to compare the area-distance relationships determined by the two...... inclusion of sinuses. A similar difference in AR was seen in two subjects before and after the nasal cavities were flushed with saline to fill up the maxillary sinuses. The measured volume in the first 50 mm of the nasal cavity models was unaffected by the sinuses, but the volume in the first 70 mm...... from the contralateral nasal cavity. We conclude that the maxillary sinuses may significantly contribute to the acoustically determined areas in the posterior part of the nasal cavity and the epipharynx, especially during decongestion, and may explain a part of the difference between area-distance...

    Full Text Available Ectopic tooth eruption into an area other than the oral cavity is rare. Nasal septum, mandibular condyle, coronoid process and infratemporal fossa space have been reported as frequent locations for ectopic tooth eruption. Ectopic teeth located within the maxillary sinus may be asymptomatic, found only in routine examinations. Headache, sinusitis and nasal obstruction are some of the associated symptoms. The differential diagnosis includes foreign bodies (rhinolith, infections (syphilis and tuberculosis, benign lesions (hemangioma, osteoma, calcifi ed polyp and malign lesions (osteosarcoma. Upper third molars located within the maxillary sinus may be associated with the development of mucocele or dentigerous cyst. The aim of this paper was to describe the case of a 24-year old female patient with an ectopic right upper third molar in the maxillary sinus. A hyperdense area was observed with sinus obliteration, consistent with mucous material.

  11. Clinical consideration of fungal paranasal sinusitis

    International Nuclear Information System (INIS)

    Fungal paranasal sinusitis is included in the differential diagnosis of unilateral paranasal lesion. Recently the incidence of fungal paranasal sinusitis has been increasing. We reviewed 24 patients (9 males and 15 females) with fungal paranasal sinusitis treated at Muroran City Hospital between January 2001 and May 2006, and clinical presentation and CT findings with those of 56 patients (36 males and 20 females) with chronic unilateral sinusitis. Fungal sinusitis patients ranged in age from 45 to 87, and the average age was 65.9 years old. In contrast, the age of chronic sinusitis patients ranged from 24 to 83, and the average age was 54.4 years old. The chief complaint of both fungal sinusitis and chronic sinusitis included rhinorrhea, nasal obstruction and post nasal discharge. CT exam was performed in all patients. In 23 cases of paranasal fungal sinusitis and 54 cases of chronic sinusitis the findings involved the maxillary sinus. The most common observation (69.6%) was bone density within the affected sinus in fungal sinusitis. However, only 2 cases of chronic sinusitis (3.9%) showed calcification. All cases of fungal sinusitis were diagnosed by pathological examinations. Most cases were proved to be aspergillus, while only one case was mucor. We treated all cases surgically, 18 cases underwent Caldwell-Luc's procedure and 5 cases underwent endoscopic sinus surgery under local anesthesia. (author)

    Full Text Available Antrochoanal polyp (ACP is a benign lesion which arises from the mucosa of maxillary sinus, fills it and expands through natural ostium towards choana protruding in the epipharynx. Objective: to present our experience in endoscopic surgery of ACP. Material and methods: prospective study included 24 patients operated at the Institute of Otorinolaryngology and Maxillofacial surgery, Clinical Center of Serbia, Belgrade, in the period 2002- 2004. Subjective symptoms, endoscopic and CT findings were evaluated postoperatively, following up the patients in the period 12-20 months. Subjective difficulties of patients were tested by 100mm-analogue scale, while endoscopic and CT findings were demonstrated by three-stage scale from 0 to 2. Applying the technique of ACP extraction in Trendelenburg’s position and approaching the part which protrudes in the epipharynx, we successfully removed the endonasal part by means of curved forceps for epipharyngeal biopsy. By endoscopic middle meatotomy, the natural ostium of maxillary sinus was expanded and pathological process from the very sinus was successfully removed. Results: only one female patient had the majority of symptoms after the operation, while all others had no complaints. Endoscopic and CT findings were normal in all patients at the latest control, without any signs of ACP recurrence. There were no intraoperative or postoperative complications. Conclusion: minimal damage to sinus mucosa due to forceps is lesser problem than complications developed upon creating even the miniature opening in the canine fossa. Using this technique, a dexterous surgeon may successfully extract pathological process with minimal incidence of recurrence, and, more important, with no complications and maximally fast recovery of patients. .

Nuestro propósito es comunicar nuestra experiencia después de intervenir 131 casos. Materiales y métodos: Se analizó una serie de 131 procedimientos llevados a cabo en 91 pacientes consecutivos, entre 1996 y 2007. La edad media fue de 50,43 años (23-69. El control radiológico pre y postoperatorio se realizó mediante ortopantomografía y TC dental. Se analizó la tasa de éxito implantario (implantes osteointegrados y cargados comparando los distintos injertos, el hábito tabáquico, las patologías asociadas y la colocación simultánea o diferida de los implantes. Así mismo, el tiempo (meses necesario para cargar la prótesis se ha comparado entre los diferentes tipos de injerto. Resultados: En las zonas aumentadas se colocaron un total de 228 implantes roscados. La altura preoperatoria media del suelo del seno fue de 6,59±2,11 mm y la postoperatoria de 14,57±2,33 mm. El seguimiento medio fue de 2,94 años (1-12. La tasa de éxito implantario global fue de 96,91%, no habiéndose encontrado diferencias significativas entre los distintos injertos, patologías asociadas o el hábito tabáquico. Conclusiones: En base a este análisis retrospectivo, se concluye que la elevación de seno es una técnica versátil, eficaz, segura y predecible; con una tasa de éxito implantario muy alta independiente del tipo de injerto, comorbilidad, hábito tabáquico y colocación simultánea o diferida de los implantes. El empleo de injerto óseo autólogo requiere un tiempo de espera para la carga protésica significativamente menor.Purpose: Maxillary sinus elevation surgery is one of the most versatile surgical procedures in maxillofacial surgery: there are various approaches to the sinus, different materials for sinus grafting, other preprosthetic procedures can be associated and the implants placement can be simultaneous or delayed, depending on the initial bone height. The aim of this study was to demonstrate this versatility by means of reporting the clinical outcome of sinus augmentation surgery in 131 cases. Materials and Methods: 131 sinus augmentation procedures were undertaken on 91 consecutive patients (mean age 50,43 years (26-69. The preoperative and postoperative radiological study was developed by means of orthopantomography and Dental-TC. The survival rate of implants, as measured by integration and succesfull loading, was compared between different graft materials, smoking/non-smoking patients, different groups of associated pathologies and simultaneous/delayed implants placement. The time (months necessary for prosthesis loading was measured and compared between the different graft material groups. Results: 228 screw-type implants were placed in sinus lifted regions. The mean residual ridge height was 6,59±2,11 mm. The mean postsurgical ridge height was 14,57±2,33 mm. After a mean follow-up period of 2,94 years (range 1 to 12 years the global implant survival rate was 96,91%. There were not significant differences between different bone grafts, associated comorbidity and smoking habits. Conclusions: On the basis of this retrospective study, it might be concluded that the sinus augmentation surgery is a very versatile procedure. Its efficacy and predictability in terms of implant survival rate is extremely high and independent on the bone graft material, surgical technique, associated morbility, smoking habit and immediate/delayed implant placement. The use of autologous bone requires less time to load the prosthesis.

    Mucormycosis and aspergillosis are the most frequent fungal infections caused by filamentous fungi; coinfection in the same host is rare. We present a case of a 78-year-old male patient with the debut of type 2 diabetes mellitus and ketoacidosis, with swelling of the right side of the face, right facial paralysis, ptosis and a necrotic ulcer in the right palate. Facial Computed tomography showed an abscess of the right maxillary sinus. Cultured secretions revealed Aspergillus fumigatus. The pathology result of biopsies of the palate, maxillary sinus and ethmoid bone was consistent with mucormycosis. The patient was treated with voriconazole, amphotericin B deoxycholate, and surgical debridement of the maxillary sinus. The patient died despite the treatment. The coinfection of Rhinocerebral mucormycosis and aspergillosis should be suspected in immunosuppressed patients in order to establish early management that can permit an improved prognosis of the disease.

It's the most common benign neoplasm of the paranasal sinuses. The osteomas are located mainly in the frontal sinus (57% to 80%, followed by the ethmoidal sinuses (20%, maxillary sinuses and rarely in the sphenoid sinus. It has a discreet predominance in the male sex 1.5 and its incidence is higher in the 3rd and 4th decades of life. The treatment is surgical no matter the size. Objective: To describe a case of giant osteoma of the ethmoidal sinus including a brief literature review. Case Report: JDA, male, 33 years old, presented with a right constant nasal obstruction for 01 year. Upon exam, he presented with facial asymmetry with lateralization of the right ocular globe. The computed tomography of the paranasal sinuses showed a lesion with density of soft parts occupying partially the right nasal cavity, ethmoid sinus and right maxillary. The patient was submitted to surgery with full exeresis of the lesion. The anatomopathological exam confirmed osteoma. The patient evolved without evidences of the lesion recurrence. Final Comments: The osteomas in the ethmoidal sinus, irrespectively of the size and due to the risk of complications, must be operated.

  2. Absence of pulmonary aspiration of sinus contents in patients with asthma and sinusitis

    International Nuclear Information System (INIS)

    The frequent association of asthma and paranasal sinusitis has been ascribed to a nasobronchial reflex, aspiration of sinus secretions, or enhanced beta-adrenergic blockade. We investigated possible pulmonary aspiration in a pilot study (eight patients) and follow-up study (13 patients) by means of a radionuclide technique. In the pilot study, the aim was to demonstrate aspiration as well as visibility of the radionuclide in the thorax during a period of 24 hours. The radionuclide was initially placed bronchoscopically in the bronchial tree in four patients and was still clearly visible in the same position after 24 hours in three patients. Aspiration from the nasopharynx was unequivocally demonstrated in two of four patients with depressed consciousness. The follow-up study population consisted of four patients with maxillary sinusitis only and nine patients with sinusitis and asthma. The radionuclide was placed in a maxillary sinus during therapeutic puncture. In the patients with only sinusitis as well as patients with asthma and sinusitis the radionuclide could be demonstrated in the maxillary sinus, nasopharynx, esophagus, and lower gastrointestinal tract during a 24-hour period. However, no pulmonary aspiration of radionuclide could be demonstrated in any patient. We conclude that seeding of the lower airways by mucopurulent secretions is unlikely to account for coexistent pulmonary disease. The association is probably related to generalized mucosal disease affecting both upper and lower airways

    The Le Fort II osteotomy is a relatively rare operation. The posterior wall osteotomy of the maxillary sinus (MS) is often difficult for Le Fort III. We developed the transmaxillary sinus approach (TSA) for the Le Fort II osteotomy that cuts the posterior wall of the MS directly. This report illustrates this easy-to-use procedure for the Le Fort II osteotomy in syndromic craniosynostosis. This procedure was performed in an 18-year-old patient with Apert syndrome and a 15-year-old patient with Pfeiffer syndrome. The thin anterior walls of the MS were removed through an intraoral approach to look inside the MS. Then, the posterior walls were cut by chisel under direct vision using light. The other osteotomy was performed as usual. Distraction osteogenesis with internal and external devices was used in combination. The advantages of TSA are the direct posterior wall osteotomy of the MS with no down fracture and minimal invasiveness to the mucosa of the MS under direct vision. However, the disadvantage is that TSA becomes a blind procedure in a case with no MS or hypoplasia. We developed the TSA for the Le Fort II osteotomy, which could provide direct observation and perform the posterior wall osteotomy of the MS without down fracture. We believe that TSA is an effective surgical procedure for the Le Fort II osteotomy. PMID:27014548

    Forty-one cases of recurrent cancer in the maxillary sinus and ethmoid sinus were treated by Nd:YAG laser, CO2 laser, PDT, and operation. The partial skull fundus invaded by the advanced carcinoma in the maxillary sinus and ethmoid sinus was resected with laser through the cranial facial section. The cancer in the maxillary sinus is the most common in primary paranasal carcinoma, accounting for 80 percent. The malignant tumors in the ethmoid sinus are minor. Radiation and operation are usually performed in them, but it is easy for the cancer to recur after treatment. To save and continue life, 41 cases of recurrent carcinoma in the paranasal sinuses were cured by laser and PDT from 1979 to 1991.

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

    International Nuclear Information System (INIS)

    We studied computed tomographic findings in the axial sections of postoperative maxillary cyst diagnosed histopathologically. The results were as follows: 1. Nineteen patients (11 males and 8 females) were studied. The average age was 44.9 years and the average period after the initial surgery of maxillary sinus was 24.3 years. 2. The lesion occupied the maxillary sinus horizontally in 13 cases and the inferior border of the lesion extended to the alveolar area in 17 cases. The forms of the lesions fell into three types; absorbed bone type, simular sinus type and unsettled type. The lesion was unilocular in 15 cases. 3. The lesion protruded into the soft tissue in 15 cases. 4. The CT numbers of the lesions ranged from 28.5 to 73.0 H.U., and the average was 44.6 H.U. 5. In the bilateral surgery cases, the findings of the opposite side fell into three types; filled bone type, reduced cavity type and soft tissue density area type. (author)

    Chronic sinusitis is a major cause of morbidity today. Regional variations in the incidence of this disease have been reported. The aim of this study was to evaluate the incidence of fungal infection as the causative agent of chronic sinusitis among Iranian patients. A cross sectional hospital based study was designed; the patients underwent paranasal sinus washing and maxillary sinus biopsy. All specimens were studied by light microscopy. Fungal culturing was employed to confirm diagnosis. The patients underwent Computed Tomography for sinus evaluation. Of 162 participants, 12 samples from patients showed fungal elements, 2 of them Aspergillus fulvous (1.2%), 9 of them Alternaria species (5.56%) and 1 of them Psilomysis (0.6%). All patients presented radiologic evidence of sinusitis, ranging from mucosal thickening to total opacity. In conclusion, results obtained showed a low prevalence of fungal sinusitis among Iranian patients with chronic sinusitis. Findings also showed that Alternaria is the most causative agent.

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

    Paranasal sinus cancers are rare diseases, accounting for about 5% of all head and neck malignancies. The variety of histological types and the overlapping pathological features with other entities constitute difficulties in pathologic interpretation, often requiring a skilled interpretation or a second opinion. Treatment of locally advanced disease relies on surgery and radiation therapy for operable disease, with a possible role for systemic treatment in selected histologies within a multimodal approach; unresectable paranasal sinus cancers are generally treated with a combination of radiotherapy and chemotherapy. The employment of high conformal radiation techniques, such as Intensity Modulated Radiation Therapy orcharged particle therapy, proton or carbon ion therapy may improve outcome and reduce late effects. Surgical treatment has evolved due to the progressive application of transnasal endoscopic techniques for naso-ethmoidal malignancies and due to innovative reconstructive techniques after resection of cancers of the maxillary sinus. Because of the rarity and complexity of this disease, multicenter trials represent an urgent need to improve prognosis and to reduce treatment-related effects. PMID:26520459

    An uncommon case of unilateral painless enophthalmos in a 44-year-old woman is presented. Despite the noticeable orbital asymmetry caused by enophthalmos, the patient has normal visual acuities in both eyes with unremarkable ophthalmic examination. Diagnosis of silent sinus syndrome was confirmed on the CT orbits and paranasal sinuses, showing complete opacification and atelectasis of the maxillary sinus. The patient achieved satisfactory improvements in her nasal symptom and facial appearance following functional endoscopic sinus surgery. PMID:24859556

  20. Morphological study of maxillary canine region based on CT

    International Nuclear Information System (INIS)

    The maxilla is generally known as a site where anatomical limitations make it difficult to obtain sufficient bone volume. A large amount of bone exists in the canine region between the anterior margin of the maxillary sinus and the piriform aperture margin. Although this region is crucial for implant treatments, there have not been any reports on morphological studies of the region. In this study, we investigated the morphology of the canine region based on CT, and also the morphology and position of the maxillary sinus located posterior to the canine region. The results were as follows: In the area above the anterior nasal spine, the higher the level, the smaller the mesio-distal length and the bucco-lingual width tended to become. In the area above the anterior nasal spine, the mesio-distal length and the bucco-lingual width tended to be smaller in female patients than in male patients. In the area above the anterior nasal spine, no significant differences in mesio-distal length and bucco-lingual width were observed between dentulous and edentulous jaws. The morphology of the maxillary sinus was mainly of an inverse-trapezoidal, circular, or triangular form. The position of the anterior wall of the maxillary sinus was most frequently found at the site corresponding to the second premolar. Through this study, we have reconfirmed that the canine region is vital for implant treatments in the maxilla. (author)

    Sinus pericranii is a rare anomaly that occurs when there is communication between the intracranial and extracranial venous systems. Accurate diagnosis is complicated because several other cranial masses can mimic sinus pericranii. Clinical, laboratory, and imaging assessments are all essential for identifying the anomaly. This article examines the comparative advantages of various diagnostic imaging modalities, current imaging techniques, and typical findings associated with sinus pericranii. Treatment and management options also are discussed. PMID:22461344

    Purpose This study investigated maxillary third molars and their relation to the maxillary sinus using panoramic radiography and cone-beam computed tomography (CBCT). Materials and Methods A total of 395 maxillary third molars in 234 patients were examined using panoramic radiographs and CBCT images. We examined the eruption level of the maxillary third molars, the available retromolar space, the angulation, the relationship to the second molars, the number of roots, and the relationship between the roots and the sinus. Results Females had a higher frequency of maxillary third molars with occlusal planes apical to the cervical line of the second molar (Level C) than males. All third molars with insufficient retromolar space were Level C. The most common angulation was vertical, followed by buccoangular. Almost all of the Level C molars were in contact with the roots of the second molar. Erupted teeth most commonly had three roots, and completely impacted teeth most commonly had one root. The superimposition of one third of the root and the sinus floor was most commonly associated with the sinus floor being located on the buccal side of the root. Conclusion Eruption levels were differently distributed according to gender. A statistically significant association was found between the eruption level and the available retromolar space. When panoramic radiographs showed a superimposition of the roots and the sinus floor, expansion of the sinus to the buccal side of the root was generally observed in CBCT images. PMID:26730371

    It has been reported that pediatric chronic sinusitis with antrochoanal polyp is difficult to cure because it tends to recur easily even with surgery. Therefore, in order to improve its cure rate, aggressive treatment combining polypectomy, intra-maxillary intubation through the inferior meatus, macrolide administration, etc., was attempted. Thirty-seven sides of pediatric chronic sinusitis with antrochoanal polyp and 44 sides of chronic sinusitis without polyp were evaluated after the same treatments. The mean age of patients was 9.7 years, and the mean intubation period was 20 months. Since subjective improvements in children are questionable, the efficacy was evaluated strictly on the basis of X-ray alone focusing on the maxillary sinus. Twenty-four percent of the group with antrochoanal polyp showed 'excellent' effect, i.e. almost complete resolution of the sinus findings, while 45% of the group without polyp showed 'excellent' effect, with a mean follow-up period of 3 years and 6 months. This difference was significant (P<0. 01, chi(2)-test). These results further document the intractableness of chronic sinusitis with choanal polyp in children. PMID:10967380

    Foreign bodies in paranasal sinuses are very rare and more than half of them are encountered in maxillary sinus. Most of the foreign bodies are associated with maxillofacial trauma. Foreign body in the frontal sinus is even a rarer condition. Foreign bodies usually present with chronic symptoms and complications due to the delayed diagnosis. In this article, we report an unusual case of mucocele resulting from silicone nasolacrimal duct tube in right frontal sinus which was left or forgotten in nasal cavity after external dacryocystorhinostomy operation. The patient was treated surgically and her symptoms resolved after surgery. PMID:24283812

O objetivo foi avaliar comparativamente a precisão da tomografia computadorizada e da radiografia panorâmica, através da quantificação da neoformação óssea nesta estrutura. MÉTODOS: Foram selecionadas pacientes edentados, com altura óssea residual do rebordo gengival ao soalho do seio maxilar menor que 5mm. O enxerto medular de crista ilíaca fragmentada isolado ou misturado com HA foi colocado através da parede lateral no soalho atrófico da cuba maxilar por via submucosa. A avaliação quantitativa e qualitativa foi feita através da radiografia panorâmica e tomografia computadorizada, sendo utilizado na análise estatística a distribuição t de Student (prevalência de 0,05 para análise das variâncias, considerado que a leitura dos laudos radiológicos foi feita por dois especialistas, medindo a distância entre os pontos inferiores e superiores do enxerto no soalho do seio maxilar. RESULTADOS: Tivemos um ganho médio de 14,8mm em todos os procedimentos, com um erro maior que 3mm em 16 procedimentos (64% e incorporação satisfatória do enxerto ósseo suficiente para futuro implante dentário. CONCLUSÕES: A tomografia computadorizada foi o método de escolha na avaliação qualitativa e quantitativa da incorporação de enxerto autólogo não vascularizado em seio maxilar atrófico.BACKGROUND:There are different methods to evaluate bone grafts in the maxillary sinus. Panoramic radiography is the most common one, even though assessment could be difficult. Occasionaly computerized tomography (CTis another option but cost and radiation in excess should be considered. Our objective is to compare these two imaging methods. METHODS: Both panoramic radiogrphy and CT scan methods were used on 25 procedures in 14 patients on post-operative sinus lift with autogenous bone graft from the iliac crest. Two radiologists evaluated the quantity of the newly formed bone and the quality of the exam for each patient, through different imaging groups. RESULTS: The quantitative bone evaluation between the two types of exam showed a statistically significant difference (Student t-test=0,05 In some cases the difference was up to 14,8 mm between exams on the same patient, having an error of more than 3mm in 16 procedures (64%. CONCLUSIONS: It can be concluded that the quality of the image on the computerized tomography is superior and it is the most reliable method to determine the area of bone augmentation of the maxillary sinus after an antroplasty.

    Postoperative maxillary cysts are locally aggressive lesions, usually developing as delayed complications many years after radical antral surgery. This report describes a case of bilateral postoperative maxillary cysts following orthognathic surgery performed approximately 21 years previously. The patient complained of stinging pain on her right cheek. Radiographic examination revealed low-attenuation lesions on both maxillary sinuses with discontinuously corticated margins without distinct expansion or bone destruction. The cysts were enucleated with the removal of metal plates and screws for pain relief. Histopathological examination confirmed the diagnosis of postoperative maxillary cysts lined by ciliated, pseudostratified columnar cells. The patient has remained asymptomatic thus far, and there was no evidence of local recurrence at 21 months of postoperative follow-up.

    Full Text Available Background/ objectives: Fungus balls are extra-mucosal collections of fungal elements, usually localized to a single sinus cavity, commonly the maxillary sinus. They appear as partial or complete heterogeneous opacification of the involved sinus with occasional metal dense opacities on CT scan. Here we report a case series of fungal sinusitis with multiple sinus involvement. Materials and methods: We report a case series analysis of 46 cases of fungal sinusitis managed in our department for the past 3 years. Mean age in our study group was 32.45 years, with 15 males(mean age – 35.46 yrs and 31 females ( mean age –31 yrs. All were operated with endoscopic sinus surgery after CT findings positive of fungal sinusitis. Result: Fungal ball was seen in 36 (78.26% cases and invasive fungal sinusitis were seen in 8 (17.39%cases. 4 cases did not yield any growth and only secondary bacterial infection were seen on bacterial culture. 34 cases had disease in the maxillary sinus. 9 cases had bilateral growth and the rest unilateral only. 16 cases had disease in the sphenoid while 6 cases had both maxillary and sphenoid disease. 2 cases had ethmoidal disease. Conclusion: Endoscopic sinus surgery is treatment of choice for non-invasive fungus ball. Local or systemic antifungal therapy are reserved for extensive and invasive fungal diseases.

    Magnetic resonance images of 47 patients with postoperative maxillary cyst were analyzed for size, location, and signal intensity. The smallest cyst was confirmed at surgery to be 1 cmx1 cmx1 cm and the largest 5 cmx5 cmx5 cm. The cysts were usually found in the superomedial and inferomedial parts of the maxillary sinus (44%). Many patients (60%) had multiple cysts or bilateral cysts (30%). In most the signal intensity was low in the T1-weighted SE (500/40) images and high in the T2-weighted SE (2000/80) images. Cysts with a hemorrhagic component, though rare, showed high signal intensity in both T1-and T2-weighted images. (author)

  15. CT images of unilateral sinus lesions

    International Nuclear Information System (INIS)

    Computed tomographic images of 49 cases of unilateral sinus lesions were examined, and 4 findings were obtained as follows; 1) On the C.T. images of malignant tumors, detection of bone destruction was easy, but its early erosion was difficult. 2) Fungus infections and papilloma of paranasal sinuses demonstrated bone thickness as well as destruction, and this finding would serve as a differential point from malignant diseases. 3) From the C.T. values of soft tissue shadows in the maxillary sinus, it was impossible to differentiate malignant from benign lesions. However, a calcified or non-homogenous soft tissue shadow was seen only in cases of fungus infections and maxillary adenocarcinoma in malignant tumors, and it would be clinically a very important differential point. 4) Many of the unilateral sinus lesions will prove to be indications for surgery, except acute and allergic sinusitis. The paranasal C.T. examinations should be performed if the case does not respond to a conservative therapy over a month, and a case showing bone destruction by the C.T. images would require an exploratory Caldwell-Luc operation.

    Inverted Papilloma is a benign neoplasm orginating from the schneiderian membrane of nose and paranasal sinus cavities. It has varied clinical and histological involving lateral nasal wall, septum, ethmoids, maxillary and sphenoid sinuses and at times involves skull base. Interesting three cases are reported because of varied presentation of inverted papilloma.

    Full Text Available Fungal involvement of the paranasal sinuses is frequently observed in the immunocompromised host and it can become lifethreatening if it is not diagnosed. Definitive diagnosis is made by tissue biopsy and culture. In this study biopsy materials of maxillary, ethmoidal and frontal sinuses of 60 patients with clinical manifestation of sinusitis and no response to medical therapy were assessed by mycological and pathological methods for the presence of fungi. Invasive fungal sinusitis was diagnosed in 3 patients and etiologic agents were Candida albicans, Rhizopus sp. and Aspergillus fumigatus. Predisposing factors in these patients were leukemia, diabetes mellitus and previous sinus and polyp surgery, respectively. Allergic fungal sinusitis also was seen in one patient and Alternaria sp. isolated from the biopsy material. Only the patient with allergic form of disease survived but all the patients with invasive form of fungal infection were expired. This clearly underscores the need of early recognition of fungal sinusitis in at risk population in order to start urgent treatment. In this study Nocardia asteroids also was isolated from the biopsy sample in a patient with sinunasal adenocarcinoma.

  4. Selective intra arterial infusion chemotherapy for malignant nasal and paranasal sinus tumors

    International Nuclear Information System (INIS)

    Since 1998, we have treated 14 malignant nasal and paranasal sinus tumor patients with selective intra arterial infusion chemotherapy. We report results for 7 of maxillary sinus, 3 of sphenoid sinus 1 of ethmoid sinus, and 3 of the nasal cavity. Only 1 maxillary sinus case involved recurrence. Intra arterial infusions of cisplatin (100 mg/body) was delivered rapidly to the tumor and usually repeated for 4 times. Conventional external-beam irradiation (2 Gy per fraction x 30) was also used. Complete response cases were 9 of 14 and control of the local lesion found in all new cases. These results indicate that intra arterial infusion therapy is effective against advanced malignant nasal and paranasal sinus tumors. (author)

    2016-01-01

    Single-tooth osteotomy is a surgical technique in which the tooth and adjacent bone with sufficient soft tissue are repositioned in a single step or moved orthodontically. It is not used in the maxillary posterior region because of poor accessibility, bleeding complications, and anatomical limitations such as the maxillary sinus. However, the development of piezoelectric surgical devices and the popularization of the sinus floor elevation procedure have simplified the approach to the posterior maxillary area. This article reports two cases of single-tooth osteotomy of ankylosed teeth that were performed safely in the posterior maxilla with the use of a piezoelectric device and a sinus membrane elevation. In addition, several merits of this approach as compared with conventional osteotomy are described. PMID:26697561

  7. Assessment of the relationship between drowning and fluid accumulation in the paranasal sinuses on post-mortem computed tomography

    International Nuclear Information System (INIS)

    Recent reports have detailed common computed tomography (CT) findings in drowning victims, most notably fluid accumulation in the maxillary and sphenoidal sinuses. This CT finding could help forensic doctors to diagnose drowning. This study retrospectively investigated 151 subjects: 39 drowning and 112 non-drowning cases. Pearson's chi-square tests demonstrated that fluid accumulation in the maxillary or sphenoidal sinuses was associated significantly with drowning (p = 0.0001). The sensitivity of the drowning diagnosis was 97%, specificity was 35%, accuracy was 51%, positive predictive value was 34% and negative predictive value was 98%. Drowning was significantly associated with fluid accumulation in the maxillary and sphenoidal sinuses, but the specificity and positive predictive value of the drowning diagnosis were poor. Although the presence of fluid in the maxillary and sphenoidal sinuses cannot be used to diagnose drowning, the absence of the fluid can be used to virtually exclude drowning.

  9. Computed tomography of chronic or recurrent paranasal sinusitis

    International Nuclear Information System (INIS)

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

    Full Text Available Sinusitis is a common disease among children. Acute bacterial sinusitis usually develops after viral upper respiratory tract infection. Acute bacterial sinusitis diagnosis in children is generally based on clinical criteria (the situation whereby the findings and symptoms of upper respiratory tract infection are more severe or last longer than expected in a viral upper respiratory tract infection. Because the treatment of acute bacterial sinusitis requires the use of antibiotics, correct diagnosis is crucial. This article reviews sinusitis pathogenesis, classification of sinusitis, the pathogens that cause sinusitis among children –primarily including acute bacterial sinusitis-, clinical findings of sinusitis and current knowledge about the diagnosis and treatment of sinusitis.

    Objectives: To evaluate graft types used for maxillary sinus augmentation and review success rates of dental implants inserted in these areas, analyzing the graft materials used, implant surface types and the moment of implant placement. Study Design: A meta-analytic study reviewing articles on sinus augmentation published during the last ten years. Results: 3,975 implants placed in sinus augmentations (with bony windows) were registered, of which 3,749 implants survived, a survival rate of 94.3%. Conclusions: When performing sinus augmentation, bone substitute materials are just as effective as autologous bone, whether used alone or in combination with autologous bone. Implant surface treatments can have an important effect on implant survival and it would appear that roughened surfaces are the best option. When implants are inserted simultaneously to grafting, a higher failure rate can be expected. Key words: Sinus augmentation, bone implant, bone regeneration, dental implant. PMID:22157658

  7. Sinusitis: imaging findings before and after treatment

    International Nuclear Information System (INIS)

    Full text: Learning objectives: To present the possibilities of Computed Tomography (CT) as a gold standard for investigation of inflammatory sinunasal diseases. The role of CT is very important in acute rhinosinuitis when sign and symptom suggest complication and in chronic sinusitis, especially before endonasal sinus surgery, for postoperative assessment and in cases of recurrences. As this method allows optimal differentiation of the air, bone and soft tissues it is able to achieve an exact visualization of a particular anatomic structures. The best representation in coronal plane of ostiomeatal unit OMU/maxillary sinus ostia, infundibulum, hiatus semilunaris, and the middle nasal turbinate and lateral nasal wall, and in axial plane of the relation: ethmoidal cells:orbit and sphenoidal sinus:internal carotid artery, are one of the biggest advantages of CT. This examination displayed not only the regional anatomy and the spread of the inflammation in the sinuses and adjacent regions, but also aided the operator in his choice of surgical approach. As CT is the best imaging modality in the evaluation of the paranasal sinuses, the question about the radiation dose became very important. The dose was reduced to protect the eye lenses, with no loss of image quality and no signification noise increase. There are many different techniques and recommendations for the CT study of the sinuses, but still no definite idea about the optimal technique for investigation in this region. This is the aim of the lecture - to develop an optimal study for preoperative and postoperative CT examination of the paranasal sinuses

  8. Evaluation study of the sinus lift technique in combination with autologous bone augmentation in dogs' frontal sinus. Limited cone beam CT image and histopathological analyses

    International Nuclear Information System (INIS)

    The posterior area of the maxilla has often been considered inadequate for the insertion of dental implants due to insufficient height of the alveolar bone by atrophic reduction and the maxillary sinus expansion. This anatomic problem may be resolved with augmentation of the floor of the maxillary sinus. The purpose of this study is to evaluate the effectiveness of sinus lift and grafting with the iliac crest bone performed in the dog frontal sinus as a model of the human maxillary sinus. Time course evaluations of bone volume after insertion of implants were performed by the limited cone beam CT (Ortho-CT), histopathological study and NIH-image digital analysis. New bone formation was identified as early as 2 weeks after the implant insertion. The bone volume was increased continuously until 13th week. High-density bone was found in the cervix of the implant after 26 weeks. However, the bone was lost at apex area of the implant and air cavity of the frontal sinus expanded. Ortho-CT findings showed good correlation with histopathological course of the lesion and bone volume identified by the NIH image analysis. The results revealed first time whole course of the bone remodeling after implant insertion into the frontal sinus of a dog. The data also provide an appropriate timing of the implant prosthesis and promise usefulness of the Ortho-CT in planning efficient implant treatment. (author)

    When a soft tissue mass in the bony wall of the paranasal sinus is present. It is difficult to make a distinction between tumor and inflammatory mass on CT. Fungal sinusitis may have soft tissue attenuation on the bony wall of the sinus, bony sclerosis, focal bony destruction, and calcific areas on CT. This is a report of four proven cases of fungal sinusitis, aspergillosis in 3 cases and mucormycosis in 1 case. All 4 patients had CT and one patient had MRI. On CT, bony sclerosis and destruction were well visualized in all cases. On MRI, mycetoma in the maxillary sinus was hypointense on T1 weighted images and more hypointense on T2 weighted images. Although CT appears to be the best modality for initial examination of the patient with sinusitis, the differentiation of fungal sinusitis from tumor mass or other entity may be better accomplished with MRI.

    A calcifying cystic odontogenic tumor (CCOT) is an uncommon odontogenic tumor with a predilection for the anterior part of the jaws. We report on 2 cases of CCOT in the posterior maxilla involving the maxillary sinus. In the first case, conventional radiography found a well-defined unilocular lesion. Internal calcification was identified on cone beam computed tomography (CBCT) images. Radiographically, the second case showed 2 large locules with a large complex odontoma and an embedded third molar. By revealing the internal calcification of the lesion, CBCT was helpful in the differential diagnosis of the first case. In both cases, CBCT illustrated the tumor extension and the relationship of the tumor to the maxillary sinus. Therefore, CBCT was an important tool for developing effective treatment plans for lesions in the posterior maxillary region. PMID:25201118

    2015-01-01

    Open sinus lift surgery is a form of pre-prosthetic surgery for increasing the quality and quantity of bone in the posterior region of the maxilla. Pre-operative assessment of the maxillary sinus is essential for the success of this surgery. PubMed search was carried out in English language literature for open sinus lift surgery and cone-beam computed tomography (CBCT). The results focused on anatomic variants, vascular anatomy, complications, osteotomy/ostectomy window dimensions and thickness of the Schneiderian Membrane. 59 articles were included in this review. Features other than the height and the width of the residual alveolar ridge that should be evaluated in preoperative CBCT scan include the thickness of the lateral maxillary sinus wall, the presence of the alveolar antral artery and its diameter, the maxillary sinus floor width and angulation, irregularity of sinus floor, intimate relation of Schneiderian membrane with the roots of the adjacent teeth, sinus septum, and the quality of subantral bone. Other conditions that occasionally may be observed in special situations are also explained. More than ten parameters should be checked in evaluating CBCT images of paranasal sinuses other than the width and the length of the residual ridge in the posterior region of the maxilla. Each of them may have a significant impact on the results of the open sinus lift surgery. PMID:26435632

According to its severity, it may be classified into three clinical-radiological stages. Objective: To report a case of stage II CMA associated with subclinical visual field defect. Case Report: A 34-year-old woman presented with a 15-year history of recurrent episodes of sinusitis and intermittent right facial discomfort for the past 5 years. She denied visual complaints, and no facial deformities were observed on physical examination. Paranasal sinus computed tomography (CT demonstrated a completely opacified right maxillary sinus with inward bowing of its walls, suggesting the diagnosis of stage II CMA. A computerized campimetry (CC disclosed a scotoma adjacent to the blind spot of the right eye, indicating a possible damage to the optic nerve. The patient was submitted to functional endoscopic sinus surgery, with drainage of a thick mucous fluid from the sinus. She did well after surgery and has been asymptomatic since then. Postoperative CT was satisfactory and CC was normal. Discussion: CMA occurs because of a persistent ostiomeatal obstruction, which creates negative pressure inside the sinus. It is associated with nasosinusal symptoms but had never been described in association with any visual field defect. It can be divided into stage I (membranous deformity, stage II (bony deformity, and stage III (clinical deformity. The silent sinus syndrome is a special form of CMA. This term should only be used to describe those cases with spontaneous enophthalmos, hypoglobus, and/or midfacial deformity in the absence of nasosinusal symptoms.

    Purpose: To describe variations of paranasal sinus development in patients with cystic fibrosis (CF) and in non-CF patients examined for inflammatory sinonasal disease. We focused on anatomic variants that predispose to orbital and cerebral penetration during functional endoscopic sinus surgery (FESS), e.g. hypoplasia of the maxillary sinus and low ethmoid roof. Material and Methods: One hundred and sixteen CF patients (3-54 years, median 18) and 136 control patients (7-51 years, median 31) were examined with coronal CT of the paranasal sinuses. CF patients were grouped according to number of confirmed mutations: CF-2 (n=70), CF-1 (n=32), CF-0 (n=14). CT images were evaluated with respect to paranasal sinus development, pneumatization variants and bony variants. Results: Frontal sinus aplasia and maxillary, ethmoid, and sphenoid sinus hypoplasia were markedly more frequent in CF-2 than in control patients. No CF-2 patient had pneumatization variants such as Haller cells or concha bullosa. Low ethmoid roof was seen in 30% of CF-2 children, but in no control children. CF-1 and CF-0 groups had prevalences of aplasia and hypoplasia intermediate to that of CF-2 and control patients. Conclusion: Genetically verified CF patients had less developed sinuses, lacked pneumatization variants, and more often had anatomic variants that predispose to complications during FESS. Normally developed sinuses and pneumatization variants in some genetically unverified CF patients (CF-1, CF-0) suggest that these patients may be erroneously diagnosed.

  18. Clinical evaluation of asymptomatic sinus disease detected by MRI

    International Nuclear Information System (INIS)

    The detection of lesions of the paranasal sinuses as incidental findings during magnetic resonance imaging of patients suspected of intracranial disease who have no nasal symptoms has been far more common than we expected. The present study was performed on 325 patients with a mean age of 60.7 years. Medical histories were taken whether they had any nasal symptoms or not. Asymptomatic sinus disease was present in 41.6% of the 257 patients who had no nasal symptoms, and 9.7% of the patients had either marked mucosal thickening, excessive fluid or polyps in the maxillary sinuses. Although the mean age of these patients was comparatively high, we can infer that 1 in 10 have relatively severe sinus lesions. Mucociliary transport time was measured using the saccharin method in 15 patients who had sinus disease but no nasal symptoms. The mean transport time was 15.6 minutes and within normal limits. Routine ENT examination revealed no lesions in the nasal cavity of any of the subjects. We classified the patients with asymptomatic sinus disease into two groups -- group A: patients with sinus disease associated with some nasal manifestations but who did not complain about them, and group B: patients who had sinus disease but did not have any nasal problems. Group B represents genuine asymptomatic sinus disease in the narrow sense. Most asymptomatic patients in this study appeared to belong to group B. They had some sinus disease, but because their mucociliary function in their nasal cavity was normal, they did not have any nasal symptoms. When we find patients with asymptomatic sinus disease, we have to determine which group they belong to by examining their nasal cavity and measuring their saccharin time. Patients in group A should be medically treated, but those in group B should be followed without medical treatment. (author)

    This study was designed to clarify the three dimensional features of naso-maxillary complex in cleft lip and palate (CLP) by using computed tomography (CT) and to examine its change following an upper dental arch expansion. Sequential CT images with 2mm-thickness were obtained for 11 unilateral CLP boys (UCLP), 6 bilateral CLP boys (BCLP) and 4 boys without cleft (non-cleft). Additionally, two serial sets of upper dental cast before and after dental arch expansion coupled with CT images in UCLP were used to evaluate the effect of dental arch expansion on the naso-maxillary complex. UCLP demonstrated a remarkable naso-maxillary deformity characterized by a decreased volume of maxillary sinus in comparison with the non-cleft patients. Both the volume and shape of nasal cavity were significantly different between the cleft and non cleft side. Naso-maxillary morphology of BCLP, however, was similar to that of the non cleft except for the decreased volume of alveolar arch. Comparative study of UCLP and BCLP showed a significant difference in naso-maxillary morphology. There were some significant correlations between the dental arch expansion and change of each naso-maxillary component, suggesting the effect of expansion stress on the naso-maxillary complex in UCLP. However, deformation caused by expansion stress varied, depending on each component of the naso-maxillary complex. (author) 61 refs.

    The objective was to determine whether or not there exists a clinical-radiological correlation in chronic sinusitis of anterior paranasal sinus and to quantitatively evaluate the importance of osteomeatal complex structures and anatomic variants in chronic sinusitis etiopathology. We analyzed 208 nasal fossae with high-resolution and low-irradiation coronal computed tomography. The following inclusion criteria we established: one case control and one control group. We considered any chronic thickness of sinusal mucosal as a radiological indicator of chronic sinusitis. We evaluated the mucosal thickness of internal, external, superior and inferior maxillary walls, the addition of four maxillary walls and the maximal mucosal thickness in frontal sinus and anterior ethmoidal cells. We also obtained 15 parameters of osteomeatal complex structures and anatomical variants in each nasal fossa, and we correlated them statistically with chronic sinusitis radiological indicators. Uncinate process length is the only anatomic element from which we have been able to obtain a statistically significant cut point between case and control groups, but only with a sensitivity of 51.6%, specificity of 71.2%, positive predictive value of 74.2%, and negative predictive value of 47.9%. No association of radiological parameters exists that can explain chronic sinusitis. (orig.)

  4. Computed tomography of malignant tumors of the nasal cavity and paranasal sinuses

    International Nuclear Information System (INIS)

    Staging of malignant tumors of the nasal cavity and paranasal sinuses by computed tomography (CT) was studied in a total of 49 patients, 33 with squamous cell carcinoma and 16 with tumors of other histologic types. Involved sites by the tumor were studied, and clinical staging was made using CT findings alone according to AJC classification for maxillary sinus tumors. Surgical findings for comparison were available for most cases. Of 33 squamous cell carcinomas and of 16 tumors with other histologic types, the maxillary sinus was the site of origin in 29 and eight, respectively. Of these 37 maxillary sinus tumors, 11 were staged T3, 26 T4, and none was staged T1 or T2. None of these tumors were down staged, and one T3 was upstaged after surgical procedures, although all sinuses were not explored in some cases. Sinusitis due to obstruction was indistinguishable from the tumor without bone destruction. And the determination of the site of origin was difficult in some cases. Despite these, CT should be used for pretreatment evaluation of the tumors of these sites

    Numerous studies have shown that placement of implants in the maxillary region with resultant successful osseointegration can be achieved by the use of sinus lift procedures using piezosurgical technique. In this case report a middle aged patient had come to the outpatient department of A. J. Institute of Dental Sciences with a chief complaint of missing right posterior molar. Since the radiographic ball marker showed only 4 mm bone below the sinus in #16 region, direct sinus lift procedure was done for placement of a dental implant. Piezosurgery was performed, as it reduces the risk of damaging vital soft tissues such as nerves, dura matter and blood vessels. To stabilize the implant in the maxillary sinus region and also to stimulate bone regeneration, gamma irradiated cancellous allograft was used. Periapical radiographs were taken 10 months after implant placement which showed good bone growth over the implant collar. Bone formation in the maxillary antrum was seen clearly in the panoramic radiograph. Using piezosurgical unit, sinus lift procedure with sinus grafting proved to be less traumatic and more successful. PMID:26894191

    Full Text Available Background: Imaging abnormalities in the paranasal sinuses are regularly noted as incidental findings on MRI, however, little is known about their prevalence in the Iranian population. The purpose of this study was to classify these findings in the paranasal sinuses as seen on MRI and to investigate the prevalence, according to site and type of paranasal abnormality. Methods: In this cross-sectional study, the T2-weighted axial MRI of 256 patients with diseases unrelated to their paranasal sinuses were reviewed between May 2002 and June 2003. The findings were categorized according to the anatomic location and the imaging characteristics of the abnormality. The abnormalities recorded included total sinus opacification, mucoperiosteal thickening >5mm, air fluid levels and retention cysts or polyps. Unilateral or bilateral involvement and septal deviation were also noted. A sinus was considered normal if it was fully aerated and no soft-tissue density was apparent within the cavity. Results: Among our cases, 111 (43.5% were male and 145 (56.5% were female. Of these patients, abnormalities in one or more of the sinus groups were found in 110 subjects (42.9%, 55.5% of which were male and 44.5% were female (P=0.001. Maxillary sinus abnormalities were observed in 66.4% of the patients, while ethmoid sinus abnormalities were found in 63.6%. Of the ethmoid abnormalities, 21% were found in the anterior section, 9% in the middle ethmoid, and 8% in the posterior ethmoid. The most common abnormality found was mucosal thickening. Among our cases, 23.4% had septal deviation, which was significantly higher among those with sinusitis (29% versus 19.1%; P<0.01. Of those patients with sinus involvement, 16% were involved in the sphenoid sinus and 5% in the frontal sinus. The results obtained from the patients with sinus abnormality revealed that 85% suffered from cough, nasal obstruction, runny nose, facial pain and post nasal discharge and 24% had been diagnosed with chronic sinusitis by physician. Conclusion: Our results showed that there was a high rate of incidental abnormalities in the paranasal sinuses that are unrelated to the patient's presenting problems.

    Sinusitis is commonly reported in patients with AIDS. In addition to the usual bacterial pathogens isolated from immunocompetent patients, sinusitis in patients with AIDS may be caused by a variety of unusual bacteria, viruses, fungi, parasites, and mycobacteria. Histoplasma capsulatum has not typically been associated with sinusitis in either group of patients. We report a case of sinusitis caused by H. capsulatum in a patient with AIDS.

    Sinusitis, which primarily involves the anterior ethmoid air cells, can spread to the larger sinus cavities to cause acute and chronic secondary infection. Endoscopic and computed tomographic techniques enable earlier diagnosis and treatment of sinusitis and permanent cure. Primary care physicians should try to identify the disease before it reaches a stage where endoscopic control becomes difficult. Ultrasonography is now used in Europe to diagnose sinusitis and initiate treatment.

    AIM: Sinus X-rays are still frequently used in the evaluation of paranasal sinusitis. Many radiology departments nowadays provide the referring doctors with a single Waters' projection. Our purpose was to evaluate the diagnostic accuracy of a single Waters' view vs high resolution computed tomography (CT) in the diagnosis of paranasal sinusitis. SUBJECTS AND METHODS: A total of 134 patients with suspected paranasal sinusitis underwent a Waters' view X-ray and high resolution CT on the same day. The radiographs were evaluated independently by nine experienced radiologists, who observed each sinus separately. Sensitivity, specificity, accuracy, positive and negative predictive values were calculated for each sinus and for each observer, using the CT findings as a 'gold standard'. RESULTS: The weighted mean sensitivity for diagnosis of any abnormality in the maxillary sinus was 67.7%, specificity 87.6%, accuracy 78.6%, positive predictive value 82.5% and negative predictive value 76.9%. For this sinus the variation between observers was small, however, the sensitivity for diagnosis of any disease in the frontal and ethmoid sinuses varied widely between observers (range 1.9-54.0% and 0-58.9%, respectively). The sensitivity for the sphenoid sinus was very low (range 0-3.8%), even in radiographs which seemed to demonstrate it well. CONCLUSION: The Waters' view has its limits in the diagnosis of sinusitis of the maxillary sinuses and its contribution for diagnosing lesions in the remaining sinuses is very poor. Whenever access to CT is available, a low dose high-resolution CT study of the paranasal sinuses is highly recommended. Konen, E. (2000)

    Chronic rhinosinusitis (CRS) is a common and potentially debilitating disease characterized by inflammation of the sinus mucosa for longer than 12 weeks. Bacterial colonization of the sinuses and its role in the pathogenesis of this disease is an ongoing area of research. Recent advances in culture-independent molecular techniques for bacterial identification have the potential to provide a more accurate and complete assessment of the sinus microbiome, however there is little concordance in results between studies, possibly due to differences in the sampling location and techniques. This study aimed to determine whether the microbial communities from one sinus could be considered representative of all sinuses, and examine differences between two commonly used methods for sample collection, swabs, and tissue biopsies. High-throughput DNA sequencing of the bacterial 16S rRNA gene was applied to both swab and tissue samples from multiple sinuses of 19 patients undergoing surgery for treatment of CRS. Results from swabs and tissue biopsies showed a high degree of similarity, indicating that swabbing is sufficient to recover the microbial community from the sinuses. Microbial communities from different sinuses within individual patients differed to varying degrees, demonstrating that it is possible for distinct microbiomes to exist simultaneously in different sinuses of the same patient. The sequencing results correlated well with culture-based pathogen identification conducted in parallel, although the culturing missed many species detected by sequencing. This finding has implications for future research into the sinus microbiome, which should take this heterogeneity into account by sampling patients from more than one sinus. PMID:26834708

  16. Dynamic imaging of the nasal cavity and the paranasal sinuses with polarized 3helium MRI

    International Nuclear Information System (INIS)

    Purpose: Reduced or blocked ventilation of the paranasal sinuses is probably the most important factor in the development of sinusitis. Recently, the use of optically polarized noble gas isotopes has attracted increasing interest for use in a variety of promising MR applications. The aim of this study was to test the feasibility of imaging and visualization ventilation of the nasal cavity and paranasal sinus in MR by inhalation of hyperpolarized 3helium. The goal was to evaluate ventilation defects of the paranasal sinuses. Volunteers and Methods: Three volunteers were enrolled in the study. 3Helium was polarized to 40 - 50% by direct optical pumping. 300 ml of 100% 3helium were administered in the left nasal vestibule through a glass tube. With a closed contralateral nasal vestibule, the Valsalva maneuver was performed twice. Using a dedicated application unit, which is also used in MR imaging of the lung, an exact amount of 3helium gas was administered at the beginning of inspiration. Measurements were carried out on a clinical 1.5 T scanner. Coronal images of the nasal cavity and paranasal sinuses were acquired using ultrafast gradient-echo pulse sequence (TR = 2 ms, TE = 0.7 ms, FA 3helium gas. The signal intensity in the left maxillary sinus was higher compared to the right one. The mean signal intensity on the left side was 526±86 and on the right side 336±102. The left and right frontal sinus and ethmoid sinus only show signal of hyperpolarized 3helium after two Valsalva maneuvers. Because of the low signal intensity of the frontal and ethmoid cells their visualization was incomplete. The signal to noise ratio was 14.1 for the left maxillary sinus, 8.9 for the right side, 6.3 for the left ethmoid sinus, 5.8 for the right side and 6.6 for the left frontal sinus and 7.8 for the right side.

  17. Radiological findings in paranasal sinus mucoceles

    International Nuclear Information System (INIS)

    To evaluate the utility of computed tomography (CT) as the technique of choice in the diagnosis and study of the extension of paranasal sinus mucoceles and to assess the role of magnetic resonance (MR) imaging. We carried out a retrospective study of 57 paranasal sinus mucoceles in 56 patients who had been diagnosed and treated from 1977 to 1997. Forth-eight patients had been examined by CT and, of these, six had also undergone MR imaging. Eight patients had only plain X-rays. Most of the mucoceles (73,2%) were located in frontal or frontal-ethmoidal sinus, followed by maxillary sinus (21.5%), the sphenoid sinus was the least frequent sites (5.3%). Of the 49 mucoceles (bilateral in one case) diagnosed by CT, 27 (56.25%) presented expansion and bone destruction, 16 (33,3%) showed only expansion and 6(12%) showed no clear evidence of expansion. Thirty extended to the orbit, four to the endocranium, two to the soft tissues of the forehead and one to the pterygomaxillary fissure and the sphenoidal ridge in one, involvement of both orbits in two and pyomucocele in another. The CT findings were characteristic in nearly every case: well-defined mass, low attenuation (high attenuation when the secretions were very thick), expansive and unenhanced by contrast agents. CT is the technique of choice for the diagnosis of mucocele and to assess their extension and the degree of bone involvement. The utilization of MR imaging facilities the definition of the interface between intracranial and intraorbital structures. (Author) 25 refs

    We evaluated histologically, histomorphometrically, and tomographically the effects of the association of fresh-frozen bone allograft (FFB) with bovine bone mineral (BBM) in maxillary sinus floor augmentation. In total, 34 maxillary sinuses from 29 patients, with a mean age of 51.32 (±6.44) years, underwent sinus augmentation. Patients were divided into control and test groups (17 sinuses each). The controls were grafted with allograft bone, and the test group received a combination of FFB and BBM at a 2:1 ratio. After 6 months, bone samples were collected for histological and histomorphometric examinations. The implant survival rates were 93.02% (control group) and 100% (test group) at 6 months after functional loading. Median volumetric reductions of 28.32% (17.05-44.05) and 12.62% (5.65-16.87) were observed for the control and test groups, respectively. Statistically significant histomorphometric differences were found between the control and test groups regarding newly formed bone 12.54% (10.50-13.33) vs. 24.42% (17.62-35.92), p connective tissue 51.66% (45.57-60.97) vs. 39.30% (35.03-49.37), p = 0.007. The addition of BBM to allograft bone in maxillary sinus augmentation resulted in higher percentages of new bone formation and total bone, and permitted implant placement with a low rate of osseointegration failure at the 6-month follow-up.

    Cementoblastoma is a rare benign tumor that almost always occurs in the premolar or molar region and more commonly in the mandible than in the maxilla. We present a unique incisor maxillary cementoblastoma in an 11-year-old child not previously described. To our knowledge, only 2 maxillary cases, both related to canine teeth, were described in the international literature. Thus, the aim of this article was to discuss the clinical presentation, diagnosis, and subsequent treatment of a patient with a cementoblastoma in the anterior maxillary region. PMID:21959464

    We report detailed clinical and imaging findings of two patients with recurrent maxillary ameloblastoma. In one patient the recurrent tumour presented at follow-up examination 5 years after the initial operation. The other patients had a far advanced recurrent tumour with maxillary destruction extending into the adjacent normal structures including the infratemporal fossa, infraorbital fissure, masticator space and the left ethmoid sinus. The findings on conventional radiography including panoramic, posteroanterior and Waters' projection, and the findings of computed tomography (CT) and magnetic resonance (MR) imaging were evaluated using the following three variables: artefact degradation, lesion detectability, and conspicuity. The results suggested that MR imaging was the best imaging method for visualization of the tumours, followed by contrast enhanced CT. These two cases show that maxillary ameloblastoma can be difficult to control when it extends to the adjacent normal structures after destroying the maxilla. MR imaging was essential to establish the exact extent of the advanced maxillary ameloblastoma. PMID:9762460

    2016-01-01

    Background This study aims to evaluate the technique of sinus bone reformation, which consists of elevating the sinus membrane and placement the implant without bone graft, compared with the widely-used technique involving raising the maxillary sinus and grafting, using animal hydroxyapatite as the filler, while simultaneously fixing the implants. Material and Methods This is a retrospective study on two groups of patients who underwent elevation of the sinus membrane and simultaneous placement of the implant. The grafting technique was applied to one group, while the other had no graft. An alveolar ridge height of 4 to 7 mm was necessary. Radiological control was undertaken at 6 months and one year post-prosthetic loading. In each group 38 implants were placed. Results No significant behavioural differences were observed in the implants according to the Albrektsson success criteria. Implant failure was observed in 2 implants from the bone grafting group (success rate 93%) and in 1 implant from the reformation group (success rate 97%). In this group, bone formation was observed on both sides of each implant, the bone gain was measured using image management software (2.7±0.9mm mesial and 2.6±0.9mm distal). There was no correlation between mesial and distal bone gain and implant´s length. Conclusions The results indicate that bone reformation is a valid technique in cases involving atrophy of the posterior maxilla. Primary stability, maintenance of space by the implant, and the formation of a blood clot are crucial in this technique in order to achieve bone formation around the implant. It is an alternative to the conventional technique of sinus lift with filling material, and has several advantages over this procedure, including a lower infection risk, as it does not involve a biomaterial, reduced cost, a simpler technique, and better acceptance by the patient. Key words:Bone formation, sinus membrane elevation, maxillary sinus, bone grafting. PMID:26827071

  7. CT an MR imaging of the paranasal sinuses in cystic fibrosis. Correlation with microbiological and histopathological results

    International Nuclear Information System (INIS)

    Purpose: To compare CT and MR findings of the paranasal sinuses in patients with cystic fibrosis (CF) with microbiology and histopathology. Further, to compare microbiology from the maxillary sinuses, nasopharynx and sputum. Material and methods: CT and MR imaging of the paranasal sinuses were performed in 10 CF patients. Endoscopy and maxillary sinus aspirates were obtained (guided by the MR findings) and analyzed microbiologically and histologically. Samples from the nasopharynx and sputum were analyzed microbiologically. Results: CT and MR were equal in displaying the extent of soft tissue masses, which at CT were homogeneous, while MR showed heterogeneous signals. MR images also demonstrated circumscribed areas with signal void at the STIR sequence with corresponding high to intermediate signal at the T1-weighted sequence. P. aeruginosa was frequently cultured from these areas which we named the 'black hole sign'. Maxillary sinus cultures revealed the same bacteria as nasopharynx and sputum cultures combined. Conclusion: MR images were superior to CT in differentiating soft tissue masses in the paranasal sinuses in CF patients. Bacteria with potential for specialized iron uptake mechanisms were present in areas with signal void at the STIR sequence. Our hypothesis is that the MR 'black hole sign' can be explained by paramagnetic properties related to bacterial agents. (orig.)

    2013-03-01

    Full Text Available Paranasal sinuses are prone to a great diversity of anomalies. It is important for surgeons to be aware of variations that may predispose patients to increased risk of intraoperative complications and help avoid possible complications and improve success of management strategies. Plane x-rays can be widely used to map sinus anatomy prior to surgical intervention to limit morbidity.The frontal sinus has been used for personal identification since the early part of the 20th century as a result of its tremendous interindividual variation. The frontal sinus is present in approximately 90% of adults. However, some populations have a higher proportion of people without a frontal sinus. This study investigated the frequency of the absence of frontal sinus in Karnataka region of India. The present study was performed retrospectively on radiographs from a series of 238 cases. Abilateral absence and a unilateral absence of sinuses were found in 6(2.5 % and 2(0.84 % of cases, respectively. The clinical significance of the frontal sinuses and their absence are also discussed.

  11. Anatomic Variation of Sphenoid Sinus and Related Structures in Libyan Population: CT Scan Study

    2008-01-01

    Full Text Available Background: Sphenoid sinus is the most inaccessible paranasal sinus, enclosed within the sphenoid bone and intimately related to numerous vital neural and vascular structures. Anatomic variation of the sphenoid sinus is well documented and may complicate surgery in such a place. Objective: To outline the surgically risky anatomic variants of the sphenoid sinus as well as the variable relationships between the sinus and related neurovascular structures, for the safe removal of intrasphenoid and pituitary lesions. Materials and Methods: We undertook a prospective review of 300 paranasal sinus CT scans of Libyan patients; coronal CT scans were obtained by special parameter techniques. We assessed pneumatization of pterygoid process (PP, anterior clinoid process (ACP, and greater wing of sphenoid (GWS; we also examined protrusion and dehiscence of internal carotid artery (ICA, optic nerve (ON, maxillary nerve (MN, and vidian nerve (VN into the sphenoid sinus cavity. Results: Pneumatization of PP, ACP, and GWS were seen in 87 (29%, 46 (15.3%, and 60 patients (20%, respectively. Protrusion of ICA, ON, MN, and VN were noticed in 123 (41%, 107 (35.6%, 73 (24.3%, and 81 patients (27%, respectively; dehiscence of these structures was encountered in 90 (30%, 92 (30.6%, 39 (13%, and 111 patients (37%, respectively. Statistically, there was a highly significant association between ACP pneumatization and ICA protrusion, ACP pneumatization and ON protrusion, PP pneumatization and VN protrusion; and GWS pneumatization and MN protrusion (p-value < 0.001. Conclusion: The sphenoid sinus is highly variable; this variability necessitates a comprehensive understanding of the regional sphenoid sinus anatomy by a detailed CT scan sinus examination before surgery in and around the sinus. This study indicates the possibility of a racial anatomical variation of the sphenoid sinus in the Libyan population.

  12. Computed tomography evaluation of autogenous graft in sinus lift surgery

    International Nuclear Information System (INIS)

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

  13. Concha bullosa: frequency and appearances on CT and correlations with sinus disease in 308 patients with chronic sinusitis

    International Nuclear Information System (INIS)

    The purposes of this study were to determine the prevalence of concha bullosa in patients with chronic sinusitis, to assess the origin of the pneumatisation (from the anterior or posterior ethmoid cells), and to evaluate the significance of the concha bullosa in the genesis of inflammatory sinus disease. We reviewed the CT studies of 308 patients with chronic sinusitis, assigning four grades of pneumatisation: absent, small, medium and large. Unilateral or bilateral concha bullosa was found in 164 patients (53%). In 79% of cases it was pneumatised via the posterior ethmoidal cells and in 21% via the anterior. A small concha bullosa was associated with abnormalities of the maxillary sinus, ethmoidal cells and ostiomeatal unit respectively in 49%, 28% and 34% of cases, whereas with a large concha bullosa the association was 55%, 36% and 41% respectively on the ipsilateral side and 55%, 32% and 41% on the contralateral side. The usually accepted hypothesis that the concha bullosa may contribute to the pathogenesis of inflammatory sinus disease seems doubtful. (orig.)

  17. Amalgam tattoo: a cause of sinusitis?

    Directory of Open Access Journals (Sweden)

    José Luiz Santos Parizi

    2010-02-01

    Full Text Available Little attention has been paid to the toxicity of silver amalgam fillings, which have been used over the centuries in Dentistry. Amalgam particles may accidentally and/or traumatically be embedded into the submucosal tissue during placement of a restoration and perpetuate in such area. This article presents a case of amalgam tattoo and investigates whether it is related to the patient's repeated episodes of sinusitis. The patient was a 46-year-old woman with a 2 mm diameter radiopaque lesion in the right oral mucosa detected on a panoramic radiograph and presented as a black macula clinically. A complete surgical resection was carried out. The histopathological examination revealed deposits of dark-brownish pigments lining the submucosal tissue with adjacent lymphocytic inflammatory infiltrate and multinucleated giant cells phagocyting pigments. There was a negative staining for both iron and melanin. One year after lesion removal, the patient reported that the sinusitis crises had ceased after repeated episodes for years. It may be speculated that the inflammatory process related to amalgam tattoo seems to lead to a local immune response that causes sinusitis because it enhances the human leukocyte antigen DR (HLA-DR tissue expression.

  7. CT diagnosis of adenoid cystic carcinoma of the nasal cavity and paranasal sinus

    International Nuclear Information System (INIS)

    Purpose: To assess CT findings and their clinical value in the diagnosis of adenoid cystic carcinoma (ACC) of the nasal cavity and paranasal sinus. Materials and methods: Pre-treatment CT findings in 17 histologically proven cases of ACC of the nasal and paranasal sinus were reviewed. 3 cases had plain CT, 2 cases both pre- and post-contrast enhanced CT, and 12 cases contrast enhanced CT. There were 18 axial and 16 coronal scans. Results: Tumors originated from and localized in the nasal cavity in 2 cases. In 15 cases, tumors were located in maxillary sinus and invaded adjacent organs or/and structures, including ipsilateral ethmoid sinus, sphenoid sinus and nasal cavity, contralateral maxillary sinus, orbit, palate, infratemporal fossa, pterygopalatine fossa, parapharyngeal space, inferior orbital fissure and foramen oval. In 7 cases, lesions invaded intracranial structures as well as the cavernous sinus. Altogether there were 2 cases of stage I, 3 cases stage III, and 12 cases stage IV. Adjacent bony changes were found in 16 cases, with bony remodeling (4 cases) and bony erosion combined with expansion (12) (71%). The diameter of the mass was larger than 5 cm in 71% of the cases. In 41% of the cases, tumors were irregular in shape, mottled pattern of lucencies within the tumor was shown in 82% of cases. Scattered calcification could be identified in 3 cases. Conclusion: Most of ACC of the nasal cavity and paranasal sinus had mottle pattern of lucencies within the tumor, irregular in shape, adjacent bony remodeling and/or erosive destruction. These findings indicate the histologic and biologic characteristics of the tumor with slow growing and perineural invasion. Apart from axial scan, coronal scan and contrast administration are mandated for the diagnosis and staging ACC

  8. Computed tomographic diagnosis of postoperative maxillary cyst (POMC)

    International Nuclear Information System (INIS)

    We reviewed the computed tomographic (CT) findings of postoperative maxillary cyst (POMC) in 64 patients with 79 lesions, and evaluated its diagnostic efficacy. Typical CT finding of POMC was an expansile and homogenous soft tissue mass with bone erosion. Thin-walled capsule and bony septation were also demonstrated in 72% and 35% of the lesions, respectively. A comparison between conventional tomography and CT has been made in the same subjects for evaluation of the detectability and extention diagnosis of POMC. CT proved to be superior to conventional tomography in diagnosing the presence and the extent of POMC. We concluded that conventional tomography is not necessary in diagnosis of POMC, when full examination of the paranasal sinus is performed by CT. (author)

  9. Three cases of osteoma and an osseous fibroma of the paranasal sinuses of horses in South Africa : clinical communication

    Directory of Open Access Journals (Sweden)

    I. Cilliers

    2008-05-01

    Full Text Available Four horses were presented to the Onderstepoort Veterinary Academic Hospital with histories of facial asymmetry, nasal discharge or obstruction of normal nasal passage airflow. Radiographic examination of the maxillary sinuses of 2 cases revealed well circumscribed, unilateral, mineralised masses; the other 2 cases showed less mineralisation. The masses were accessed for further investigation by surgically created frontonasal bone flaps or trephination of the maxillary sinuses. Diagnosis of osteoma was confirmed histopathologically in 3 of the cases and of ossifying fibroma in the 4th. Two horses were euthanased directly after surgical intervention due to poor prognosis. Osteomas are by nature expansile tumours and follow the complex communication of the sinuses, and therefore are not all amenable to surgical removal. Osseous fibromas are large, solitary, expansile lesions that are rare in all species but reported most frequently in horses. They have an apparent predilection for the rostral mandible of the horse.

    2011-03-01

    Inflammation in the paranasal sinus is often observed in seasonal allergic rhinitis or with colds, but is also an indication for odontogenic tumors, carcinoma of the maxillary sinus or a maxillary cyst. The detection of those findings in dental panoramic radiographs is not difficult for radiologists, but general dentists may miss the findings since they focus on treatments of teeth. The purpose of this work is to develop a contralateral subtraction method for detecting the odontogenic sinusitis region on dental panoramic radiographs. We developed a contralateral subtraction technique in paranasal sinus region, consisting of 1) image filtering of the smoothing and sobel operation for noise reduction and edge extraction, 2) image registration of mirrored image by using mutual information, and 3) image display method of subtracted pixel data. We employed 56 cases (24 normal and 32 abnormal). The abnormal regions and the normal cases were verified by a board-certified radiologist using CT scans. Observer studies with and without subtraction images were performed for 9 readers. The true-positive rate at a 50% confidence level in 7 out of 9 readers was improved, but there was no statistical significance in the difference of area-under-curve (AUC) in each radiologist. In conclusion, the contralateral subtraction images of dental panoramic radiographs may improve the detection rate of abnormal regions in paranasal sinus.

  11. A clinical study of malignancies of the nasal cavity and paranasal sinuses

    International Nuclear Information System (INIS)

    The data of a total of 82 patients with malignancies of the nasal cavity and paranasal sinuses who were initially treated at the University of Tsukuba Hospital between 2002 and 2011 were reviewed. The mean age (±standard deviation) was 63.1 (±14.6) years, and the male-female ratio was 2.73 : 1. The tumor originated from the maxiallry sinus in 40 cases (48.8%), from the nasal cavity in 28 cases (34.1%), from the ethmoid sinus in 9 cases (11.0%), and from other sinuses in 5 cases (6.1%). At our department, treatment for maxillary cancer is initiated with chemoradiotherapy concurrently with intraarterial infusion of fluorouracil, followed by planned surgery for appropriate candidates. The disease-specific 5-year survival rate was 57.0% in our series of patients with maxillary cancer. Malignancies of the nasal cavity and paranasal sinuses may present with diverse clinical features and further investigation is needed to establish appropriate treatment strategies for individual cases.

    Endoscopic sinus surgery is a minimally invasive option for the treatment of several nonneoplastic indications, particularly for medically refractory sinusitis and polyposis. Numerous interventions can be performed through endoscopic sinus surgery, many of which may be performed together during the same procedure. There are also a variety of complications that can result from endoscopic sinus surgery. Radiological imaging plays an important role in the evaluation of patients after endoscopic sinus surgery. Thus, it is important to be familiar with the expected and complicated imaging findings associated with endoscopic sinus surgery, which are reviewed in this article. PMID:26476384

  14. Stress distribution in maxillary alveolar ridge according to finite element analysis using micro-CT

    International Nuclear Information System (INIS)

    The purpose of the present study was to evaluate stress distribution by finite element analysis in an accurate model simulating trabecular bone using micro-CT. Dentulous and edentulous maxillary jaws of Japanese adult cadavers were used (5 sides each; total, 10 sides). Imaging was performed using a micro-CT, followed by reconstruction with 3-D images. Finite element analysis models were developed using the maxilla with average bone morphometry. A load corresponding to occlusal force was applied in different loading conditions, followed by evaluation of stress distribution. In dentulous maxillas, a load was applied in the dental axis direction to the first molar crown (LD). In edentulous maxillas, a load was applied directly to a circular area 4 mm in diameter (LER0) to a cylinder 4 mm in diameter and 10 mm in height (LER10) corresponding to the first molar area. Stress was concentrated in cortical bone around the first molar, trabecular bone and cortical bone at the maxillary sinus base in LD, cortical bone of the alveolar ridge in LER0, and trabecular bone around the cylinder and cortical bone at the maxillary sinus base in LER10. LER0 showed a stress distribution markedly different from that in LD. Compared with LER0, LER10 showed a stress distribution close to that in LD. A model simulating trabecular bone allows a more accurate evaluation of stress distribution. (author)

    Primary oral melanoma is a rare neoplasm of melanocytic origin, accounting for 0.5% of all oral malignancies. The “chameleonic” presentation of a mainly asymptomatic condition, rarity of this lesion, poor prognosis, and the necessity of a highly specialized treatment are factors that should be seriously considered by the involved health provider. Here is a case report presenting a malignant melanoma of oral mucosa in 48-year-old male patient on maxillary gingiva. The lesion was removed by par...

  17. CT and MRI diagnosis of osteosarcoma in paranasal sinus

    International Nuclear Information System (INIS)

    Objective: To study the CT and MRI findings of osteosarcoma in paranasal sinus and evaluate their clinical value. Methods: All 9 eases of osteosarcoma were verified by histopathology. Imaging data were analyzed retrospectively. Results: The lesion occurred in maxillary sinus in 5 eases, in ethmoid sinus in 3 cases and in sphenoid sinus in one ease. Primary osteosarcoma was found in 7 cases. Secondary osteosarcoma occurred from fibrous dysplasia and ossifying fibroma each in one case. On CT, the involved areas revealed bony destruction associated with ill-defined and irregular soft tissue mass. The lesion showed heterogeneous density with minimal or massive tumor' bone formation, cloud-like in 3 cases, ivory-like in 2 cases, spicule-like in 2 cases, cloud- and spicule -like in one case and spicule- and ivory-like in one case. Postcontrast CT showed mild to moderate inhomogeneous enhancement in 3 cases. On MR T1WI, the lesions showed hypointensity compared to brain in 5 cases and iso-intensity in 2 cases. On T2WI, the lesions showed heterogeneous hyperintensity in 4 cases and isointensity in 3 cases with marked hypointense foci which corresponded to tumor bone on CT. Postcontrast MR imaging demonstrated moderate to marked inhomogeneous enhancement in these cases. MRI showed accurately the extent and associated changes of the lesions. The lesions invaded the orbit, pterygopalatine and infratemporal fossae, skull base and extensive craniofacial structures in 5,4,3 cases and 1 case,respectively. Conclusion: CT is the optimal modality in showing tumor bone of osteosarcoma in paranasal sinus. MRI can demonstrate optimally the invading extent of the lesions. Combined imaging modalities can provide more comprehensive information for diagnosis and therapy of osteosarcoma in paranasal sinus. (authors)

  18. Use of reconstructed CT images for evaluation of the position of screw-type temporary anchorage devices implanted in the maxillary molar region

    International Nuclear Information System (INIS)

    Temporary anchorage devices (TAD) have recently been employed for orthodontic treatment. I attempted to find the safest position for placing the screw-type TAD in the maxillary molar region. Using reconstructed CT images, I investigated the buccolingual and mesiodistal lengths of the interalveolar septums between the maxillary first premolar, second premolar, first molar, and the second molar. For the first and second molars, I measured the distance from the alveolar crest to the maxillary sinus. The results indicated that the safest position for placing a screw-type TAD was the interalveolar septum between the maxillary first molar and the second premolar at about a depth of 4-6 mm from the alveolar crest on the buccal side, and at about a depth of 2-6 mm from the alveolar crest on the palatal side.

    Antrochoanal polyp is a benign polypoid lesion orginating from the maxillary sinus antrum and extending to the choana. Our aim was to assess the clinical presentation and associated rhinological findings of antrochoanal polyp patients and to evaluate results of 2 surgical treatments termed endoscopic sinus surgery (ESS) and ESS plus mini-Caldwell operation. The study included 46 patients. Factors such as patient age, sex, history of chronic sinusitis, allergic rhinitis, septal deviations, chonca bullosa, turbinate hypertrophy, and the origin of the polyp were assessed. We also evaluated ESS and ESS plus mini-Caldwell surgical procedures for recurrences, synechia, bleeding, and ostium stenosis. Overall, there were 27 men and 19 women. The ESS approach was used in 26 cases, and 20 cases had combined ESS and mini-Caldwell procedures. The statistical significant difference between the 2 groups was only recurrence (P 0.05). We thought that lower rate of recurrence found in ESS + Caldwell group in this study was associated with better visualization of the maxillary sinus walls and, therefore, easier resection of the remnant polyp. We concluded that higher incidences of bleeding and synechia were related to the mucosal damage occurring in the septum and the inferior concha due to excessive manipulation of endoscope and surgical instruments.

  20. Incidental paranasal sinuses abnormalities in pediatric patients using computed tomography of the head and orbits

    International Nuclear Information System (INIS)

    Objective: To evaluate the prevalence and appearance of incidental paranasal sinuses abnormalities in children with no clinical evidence of rhino sinusitis using CT scans. Materials and methods: CT scans of the head or orbits of children between 0 and 18 years of age performed due to problems not related to rhino sinusitis were studied. Results: Sixty-four children were included (mean age 5.7 years; standard deviation = 3.9). Incidental sinuses abnormalities were found in 46 cases (72%). In most cases the abnormalities were mild (25/46) and mucosal thickening was the most common finding. Complete opacification and fluid levels occurred in 12 children. More than one cavity was affected in 33 patients and abnormalities were most frequently seen in maxillary sinuses, followed by ethmoid sinuses. Bilateral and symmetric findings were common. The prevalence and intensity of abnormalities were higher in children below three years of age. Conclusion: Incidental abnormalities are highly prevalent and tend to be mild in children without symptoms of rhino sinusitis. The most prevalent abnormality was mucosal thickening. Moderate and severe abnormalities occur in children below three years of age. (author)
