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 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...
متن کاملNormal Variations of Sphenoid Sinus and the Adjacent Structures Detected in Cone Beam Computed Tomography.
STATEMENT OF THE PROBLEM The sphenoid sinus is a common target of paranasal surgery. Functional endoscopic sinus surgery is likely to endanger the anatomic variations of vital structures adjacent to the sphenoid sinus. PURPOSE The aim of this study was to determine the variations of sphenoid sinus and the related structures by using cone-beam computed tomography (CBCT). MATERIALS AND METHOD...
متن کاملVaried Ophthalmic Presentations in Sphenoid Sinus Lesions
Sphenoid sinus lesions can present with a multitude of symptoms/signs including ophthalmic disturbances. We describe a total of five patients, of which two had mucoceles and rest three had fungal infection. Ophthalmic symptoms/signs were the ones we were really interested in. We also present one case which had isolated sphenoid fungal sinus. We also give details of their presentation, investiga...
متن کاملBenign expansile lesions of the sphenoid sinus: differentiation from normal asymmetry of the lateral recesses.
BACKGROUND AND PURPOSE There is a wide range of normal variation is sphenoid sinus development, especially in the size of the lateral recesses. The purpose of this study was to determine imaging characteristics that may help differentiate between opacification of a developmentally asymmetric lateral recess and a true expansile lesion of the sphenoid sinus. METHODS Coronal CT was performed in ...
