INTRODUCTION The medial maxillary sinus roof is a ridge formed by the superior margin of the maxillary sinus antrostomy. The posterior wall of the maxillary sinus is always included in operative fields. OBJECTIVE To perform a radiologic study assessing the utility of the medial maxillary sinus roof and the posterior wall of the maxillary sinus as fixed landmarks for providing a safe route of ...

The nasal valve is an anterior triangular area of the nose delineated by the inferior margin of the nasal lateral cartilage, septum, and floor of the pirif orm aperture. On inspiration, the dilator muscles of the nose elevate the cartilage and permit widening of the anterior airway. Cartilaginous nasal valve stenosis impairs valve dilatation and is a form of nasal obstruction. Since infants are...

OBJECTIVE To determine normal values in the size of nasal fossae to better delineate the concept of nasal stenosis in young infants with nasal obstruction and without choanal atresia. DESIGN Case series. SETTING Referral center. PATIENTS Consecutive sample of 62 infants (aged 0 to 6 months) with no craniofacial anomalies who underwent conventional axial computed tomography scans for a neu...

PURPOSE Chronic maxillary atelectasis is characterized by unilateral spontaneous enophthalmos and hypoglobus due to increased orbital volume secondary to maxillary sinus inward deformation. Reformation of the sinus architecture and reconstruction of the orbit are key to a successful outcome. Here, we introduce a one-staged surgery that addresses both these goals. PATIENTS AND METHODS We retro...

PATIENT Male, 27. FINAL DIAGNOSIS Recurrent epistaxis. SYMPTOMS Nasal bleeding. MEDICATION -. CLINICAL PROCEDURE -. SPECIALTY Pediatrics and Neonatology. OBJECTIVE Congenital defects/diseases. BACKGROUND Recurrent epistaxis is a common disorder among children and young adults. We report an unusual cause, intranasal supernumerary tooth causing friction with Little's area of the nas...

BACKGROUND The Le Fort I osteotomy is one of the most widely used and useful procedure to correct the dentofacial deformities of the midface. The changes of the maxilla position affect to overlying soft tissue including the nasal structure. Postoperative nasal septum deviation is a rare and unpredicted outcome after the surgery. There are only a few reports reporting the management of this comp...

From a cohort of 35 patients with hereditary haemorrhagic telangiectasia (HHT), 12 patients have undergone closure of the one or both nasal cavities during the last three years for refractory epistaxis. All had failed other forms of treatment including hormone therapy, laser coagulation and septodermoplasty. All patients were available for follow-up at six months or longer. In all patients wher...

PURPOSE To investigate the effect of perceptual inter-judge agreement of hypernasality on velopharyngeal (VP) closure prediction. METHODS Two logistic regression models were developed aiming to verify the possibility of predicting the VP closure using the following characteristics: rating of VP closure (adequate, borderline, inadequate), determined by the pressure-flow technique, degree of hy...
