BACKGROUND: The aim of the present study was to evaluate the diameter, relationship and position of the posterior superior alveolar artery and its relationship with the alveolar ridge, the medial wall of the maxillary sinus, the prevalence of pathologic conditions and the maxillary sinus septa on CBCT images. MATERIAL AND METHODS: A total of 200 CBCT images (400 maxillary sinuses) of patients over 20 years of age were evaluated. The distances between the lower border of the artery and the alveolar crest and between the artery and the medial wall of the sinus and the diameter of the artery were measured...

BACKGROUND: The aim of this study was to evaluate the validity and the inter- and intra-examiner reliability of panoramic-radiograph-driven findings of different maxillary sinus anatomic variations and pathologies, which had initially been prediagnosed by cone beam computed tomography (CBCT). METHODS: After pairs of two-dimensional (2D) panoramic and three-dimensional (3D) CBCT images of patients having received treatment at the outpatient department had been screened, the predefinition of 54 selected maxillary sinus conditions was initially performed on CBCT images by two blinded consultants individually using a questionnaire that defined ten different clinically relevant findings...

PURPOSE: Sinus elevation procedures have become a routine and reliable way to gain bone volume in the edentulous maxilla for dental implant placement. Presence of bony septations and pathology in the maxillary sinus often cause complications leading to graft or implant failure or both. The aim of this study was to retrospectively evaluate the prevalence of pathology, direction of the septa, and sinus width measured at 2 mm, 5 mm, and 10 mm from the sinus floor in maxillary sinuses using cone-beam computed tomography (CBCT)...

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...

INTRODUCTION: Presence of the maxillary sinus septum would increase the risk of sinus membrane perforation during sinus floor elevation surgery. Three-dimensional radiographic techniques are recommended for the evaluation of the maxillary sinuses. MATERIALS AND METHODS: This cross-sectional study evaluated 946 maxillary sinuses using the cone beam computed tomography. Presence of septa, number, location, height, and orientation were evaluated and recorded in data forms...

The purpose of this study was to measure the frequency, numbers, locations, orientations, and heights of maxillary sinus septa. MATERIALS AND METHODS: Reconstructed cone-beam computed tomographic images of 1,012 sinuses were analyzed using NewTom VG software (NNT 2.21, ImageWorks, Elmsford, NY). This cross-sectional study included patients who underwent radiography at the department of radiology...

Aim of this investigation is to evaluate prevalence, localization, and height of 114 maxillary sinus septa by using cone-beam computed tomography scans. The thickness of the mucosa has been measured together with the variations of the membrane in relation to those septa. A total of 228 maxillary sinuses have been considered. Septa were identified using "panorex" reconstructions and axial scans of cone-beam computed tomography using the software "eXamVision." The thickness of the mucosa has been evaluated in the paraxial scans and related to those septa where they were present...

INTRODUCTION: Maxillary sinus septas are barriers of cortical bone that arise from the floor or from the walls of sinus and may even divide the sinus into two or more cavities. Morphologically maxillary sinus septa are generally oriented in buccopalatinal orientation horizontal or sagittal orientation of the sinus septa is a rare condition. PRESENTATION OF CASE: This report presents two sinus lift case, in which observed septa in a horizontal orientation was presented...

This study aims to classify the infraorbital canal according to its position related to the maxillary sinus as observed by axial CT. It is a retrospective, cross-sectional study. This study was performed in a tertiary referral center. In this study, axial and coronal CTs of 750 patients were examined and infraorbital canals and neighboring structures were evaluated. Infraorbital canals were then classified according to their positions in relation to the maxillary sinus as seen in axial sections. Morphologic variations of neighboring structures were also noted and their correlations with specific canal types were investigated...
