anatomical variations of carotid artery and optic nerve in sphenoid sinus using computerized tomographic imaging
background sphenoid sinus is surrounded by many vital vascular and nervous structures. in more than 20% of patients with chronic sinusitis, involvement of sphenoid sinus has been observed. besides, sphenoid sinus is an appropriate route to access anterior and middle cranial fossa in surgery. therefore, it is important to have an adequate knowledge about the contents of sphenoid sinus and its pr...
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 variations in the neurovascular relations of the sphenoid sinus: an evaluation by coronal computed tomography.
AIM The sphenoid sinus is deeply situated in the skull and is the least accessible paranasal sinus. The sphenoid sinus is surrounded by vital structures such as the optic nerve and internal carotid artery, and therefore additional radiological assessment of the sphenoid sinus and the related neurovascular structures is inevitable before surgery. The aim of this study was to note the anatomic va...
متن کاملVariations in Lateral Sphenoid Sinus Wall Defects
Defects in the lateral wall of the sphenoid sinus are a rare cause of cerebrospinal fluid (CSF) rhinorrhea. The etiology of these defects may be congenital or acquired. A dehiscent lateral craniopharyngeal canal, or Sternberg canal, arises from a malunion of two parts of the developing sphenoid bone: the greater wing and the basisphenoid.1,2 Originally reported in 4% of healthy adults,3 its tru...
