Sphenoid Sinus: Anatomic Variations and Their Importance in Trans-sphenoid Surgery
Background: Over the past decades, instruments and techniques of the transsphenoidal approach have improved greatly. All of these procedures, whether microscopic or endoscopic, must pass through the sphenoid sinus to reach the lesions. The sphenoid sinus is surrounded by several vital anatomical structures. Knowing the details of the anatomy of the sphenoid sinus and the extent of pneumatizatio...
متن کاملAnatomic 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 کاملThe anatomical relations of the sphenoid sinus and their implications in sphenoid endoscopic surgery.
Alongside the past development of endoscopic sinus surgery, knowledge about the anatomy of the sinuses has become crucial for surgeons. The sphenoid sinus is one of the most variable of all sinuses. Its relations to vital vascular and nervous elements make its approach a challenge for endoscopic surgeons. These relations include the internal carotid artery, the optic nerve, the pituitary gland,...
متن کاملEndoscopic anatomy of sphenoid sinus for pituitary surgery.
Endoscopic endonasal transsphenoidal approach to the sellar region yields an alternative to classical microsurgical approaches. Endoscopes provide images that differ from microscopic view. This study aimed to highlight surgical landmarks and their anatomical relationships for pituitary surgery through endoscopic perspective. Ten sides of five adult cadaveric heads with red-colored latex injecte...
