Conclusion: We showed the changes in the pharyngeal airway space after different orthognathic surgery procedures including advancement genioplasty. There are not significantly changes between the groups underwent bimaxilary surgery, but genioplasty increase the changes in the pharyngeal airway space. Conflict of interest: None declared.

The statistical analysis was performed by means of SPSS 15.0 to validate specificity and sensibility index. Results: A total of 73 hemicervical dissection were made in our sample, and in 21 of these was possible to find 30 metastatic lymph nodes. Statistical concordance between CT and histological findings showed an interclass correlation of 0.237. RMI showed 0.506 of interclass correlation, and PET accomplished a level of 0.908. Concerning the Kappa index, PET revealed a correlation of 0.7714. Conclusions: In our study, PET revealed excellent indexes of correlation in terms of presurgical cervical lymph node extension of OCEC. Moreover, our results prove a higher reliability of PET compared to CT and RMI when staging a presurgical OCEC. Conflict of interest: None declared.

MATERIAIS E MÉTODOS: Foram avaliados 50 pacientes entre novembro de 2006 e janeiro de 2007. A medida da espessura subcutânea foi realizada com transdutor linear de 7,5 MHz posicionado transversalmente a 1 cm acima da cicatriz umbilical. Para a gordura visceral foi utilizado transdutor de 3,5 MHz posicionado 1 cm acima da cicatriz umbilical, considerando-se a medida entre a face interna do músculo reto abdominal e a parede posterior da aorta na linha média do abdome. A gordura perirrenal foi medida no terço médio do rim direito, com transdutor posicionado na linha axilar média. RESULTADOS: A reprodutibilidade interobservador foi analisada por meio do teste t de Student, com significância de 95%. Não houve diferença significativa entre as médias das medidas das gorduras subcutânea, visceral e p...

Results: The results showed that of a total of 120 surgeries performed, 11 had complications, of which 8 patients had hematomas, 1 had local infection and 2 patients had nerve injuries. Around 95% of the patients were satisfied with the aesthetic outcome. Conclusion: We showed that the subperiosteal midface-lift by temporal approach is a procedure that helps restore the relations of soft tissues with the underlying structures giving a more youthful expression. This is a technique that produces good cosmetic results in most cases, causing an increase in the malar region, improving the nasolabial fold and enhancing the small jowls. Conflict of interest: None declared.

The frontal and sphenoid sinuses are the most frequently involved sites. Herein, we present the case of a 30-year-old woman with a 6-year history of right nasal obstruction and pain in the right maxillary region, elicited by rapid changes in atmospheric pressure. Computed tomography (CT) detailed an abnormal expansion of the right maxillary sinus resulting from a process of hyperpneumatization with no evidence of bone erosion, leading to the diagnosis of PSD. Restoration of permanent pressure equilibrium in the right maxillary sinus and improvement in the patency of the nasal fossa were achieved by a subtotal resection of the medial wall of the maxillary sinus by an endoscopic approach. Two years later, the patient was asymptomatic, and a CT scan showed no progression of the disease.

The miscegenation made a unique population comprised of Indian, Asian, Caucasian, African, Mestizo, Mulatto, and Zambo. The South American patients tend to have a wider face with a skin-soft tissue envelope (S-STE) that is thicker, heavier, and has less elasticity than the Caucasian patient. Upper eyelids may hood easily. In the same way, malar eminences and round face look are more prominent. The chin can be a little retracted. With aging, the S-STE tends to sag more, making nasolabial folds and jowl area more prominent, and redundant neck skin will appear loose and heavy. Facelift is popular in South American patients. They have peculiar characteristics like heavy dark sebaceous skin which lead to peculiarities in face lifting. It is usually a procedure designed to rejuvenate all thirds of the face. In the forehead, skin excision in temporal incisions is usually necessary. Midface subperiosteal li...

Nasal biopsy has been used in research but its clinical application has not been described. We evaluated the contribution of the nasal biopsy for the diagnosis of leprosy and its correlation to skin biopsy and skin smear in untreated patients. We evaluated changes in nasal biopsy in 227 leprosy patients. Patients were clinically classified and skin and nasal biopsies and skin smear were performed. Nasal biopsy showed positivity in 100% of the lepromatous spectrum decreasing toward the tuberculoid (TT) pole. Patients with TT or indeterminate forms did not present any nasal alterations, showing that they are the true paucibacillary forms. Also, the nasal biopsies of two patients were the only exam to show positivity. The bacillary index of the nasal biopsy was strongly correlated to skin biopsy and slit-skin smear. Additionally, the agreement among the exams was good, revealing the reliability of the nasal biopsy in leprosy diagnosis. The present study showed a rate of 48% of positivity in nasal biopsy of untreated patients, correlating well with skin biopsy and skin smear. Thus, the method in leprosy diagnosis and clinical form classification has shown great reliability.

The mechanism of infectivity and dissemination of the disease are not completely known, although the nasal mucosa is supposed to have an important role in pathogenesis. To correlate the clinical and bacteriological parameters with that of nasal biopsy and immunological tests, such as lepromin and ML-Flow results, in untreated leprosy patients. Two hundred and twenty-two patients were evaluated, clinically classified and subjected to skin smear, nasal biopsy, ML-Flow, and Mitsuda test. 689% of the cases were borderline cases. Nasal biopsy revealed 91.4% positivity in those who had specific antibodies against M. leprae on blood sample. Lepromatous leprosy cases were 100% positive on ML-flow test, had a large involvement in the nasal mucosa (91%), positive skin smears (100%) and negative Mitsuda test. Nasal bacillary index showed a good correlation with ML-Flow and h...
