introduction rhinoliths are uncommon nasal masses. they are mineralized masses found within the nasal cavity. they have various clinical presentations. case presentation we report a 13-year-old boy with long-standing nasal obstruction, yellowish nasal discharge and intermittent and minimal nasal bleeding for a few weeks, who had been treated as rhinosinusitis twice. due to the presence of long-...

OBJECTIVES/HYPOTHESIS Nasal natural killer/T-cell lymphoma (NKTL) often has an infiltrative pattern in computed tomography that makes them difficult to distinguish from benign inflammatory diseases. This study aimed to design a method of measuring the thickness of the nasal floor and nasal septum, determine the critical value of mucosal thickness that may implicate these NKTL cases from benign ...

Oroantral fistula (OAF) is a pathologic, epithelialized communication between the oral cavity and the maxillary sinus. OAF most commonly results from posterior maxillary tooth or molar extraction owing to proximity of the dental roots to the maxillary antrum and the thinness of the adjacent antral floor. It also can arise secondary to implant and orthognathic surgeries, cyst and tumor removal, ...

BACKGROUND Various methods for primary repair of bilateral cleft lip have been developed, but they often produce inadequate results, such as an upturned nose or a short columella. We perform primary lip repair with muscle reconstruction to correct depression of the nasal floor and inferoposterior displacement of the alar base. Then, open rhinoplasty to project the nasal tip is performed during ...

OBJECTIVE To assess the validity of acoustic rhinometry for measuring nasal valve area in human subjects. STUDY DESIGN A comprehensive study that compared acoustic rhinometry data with computed tomography findings from scans obtained perpendicular to the acoustic axis and perpendicular to the floor of the nose. METHODS Fifty nasal passages of 25 healthy adults with no nasal disease were exa...

PURPOSE The aim of this paper is to present a large-scale long-term follow-up of dental implants placed simultaneously with nasal floor augmentation using osteoconductive bovine bone substitutes. MATERIALS AND METHODS Patients who received dental implants combined with nasal floor elevation in three dental centers between 2006 and 2012 were included in this report. Preoperative available bone...

Purpose of review Although numerous surgical techniques have been introduced thus far in order to achieve the surgical closure of nasal septal perforation, the repair of nasal septal perforation is still challenging for surgeons and operative techniques are not standardized. Furthermore, predictive factors for successful closure have not been elucidated. This review aimed to investigate predict...

PURPOSE Lateral cephalometric films were examined for their validity as a tool for the postoperative evaluation of palatal implant placement. MATERIALS AND METHODS Cephalometric and histometric data of 20 partially edentulous human cadaveric maxillae were compared. Lateral cephalograms of the specimens were made, and the palatal complex was pencil traced. In addition, low-dose dental computer...

This work reports the use of nasal leakage to achieve the pressure difference for voicing in utterance-initial Spanish stops. Multiparametric aerodynamic and acoustic data were analyzed for six Spanish speakers. Two main patterns of prenasalization were identified in postpausal voiced stops: (i) delayed nasal closure relative to the oral closure and (ii) a momentary nasal opening (nasal burst) ...
