Anatomic variations of sphenoid sinus from Cone Beam Computed Tomography images in the Iranian population
Aims: Sphenoid sinus is one of the most inaccessible paranasal sinus, and is closely correlated to many vascular and neural structures. Anatomic variation of the sphenoid sinus can complicate surgery in this area. The aim of the present investigation was to define the sphenoid sinus variations and the relevant structures using cone-beam computed tomography (CBCT). Methods: This cross-sectiona...
متن کاملAssessment of sphenoid sinus related anatomic variations with computed tomography
INTRODUCTION Frequent and broad application of endoscopic sinus surgery (ESS) in parallel with experience makes it imperative to know the anatomy and the existing pathology very well before surgery. This study examines the association between anomalies in the sphenoid sinus area in paranasal sinuses computed tomography (PNS-CT) and pathological findings and determines variations of sphenoid sin...
متن کاملAnatomic Reference for Computed Tomography of the Paranasal Sinuses and Their Openings in the Rayini Goat
Objective- to provide a reference anatomy of the paranasal sinuses of the goat by using computed tomographic modality. Design- Experimented study. Animals- Five male Rayini goats. Procedures- CT images were acquired from the head region perpendicular to the hard palate. CT windows were adjusted as necessary to obtain the optimal image for the paranasal sinuses. The images were studie...
