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...

purpose : to report a patient with sphenoid sinus mucocele (ssm) case report : the patient is a 19-year-old man who was referred to khatam-al-anbia eye center as retrobulbar optic neuritis. brain and orbital ct scan and mri revealed ssm. the patient underwent endoscopic sinus surgery and visual acuity (va) improved from no light perception (nlp) to 2 meter counting fingers. conclusion : ssm may...

PURPOSE In adults, sphenoid sinus agenesis is an extremely rare anomaly. The objective of this study was to investigate the prevalence of sphenoid sinus hypoplasia and agenesis using dental volumetric computed tomography (DVCT) in a population of Turkish individuals. MATERIALS AND METHODS DVCT scans in the axial, coronal and sagittal planes of the sphenoid sinus of 384 patients were examined ...

b a c k ground: 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 pneumatiz...

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...

PURPOSE OF REVIEW To review cause, clinical evaluation, medical and surgical management of isolated sphenoid sinus diseases. RECENT FINDINGS Early diagnosis of isolated sphenoid sinus diseases requires a high index of clinical suspicion and appropriate radiological imaging. Sphenoid sinus can be approached endoscopically via a few different surgical techniques. SUMMARY Isolated sphenoid sin...

INTRODUCTION The medial maxillary sinus roof is a ridge formed by the superior margin of the maxillary sinus antrostomy. The posterior wall of the maxillary sinus is always included in operative fields. OBJECTIVE To perform a radiologic study assessing the utility of the medial maxillary sinus roof and the posterior wall of the maxillary sinus as fixed landmarks for providing a safe route of ...

OBJECTIVE To clarify the three-dimensional anatomical features of the sphenoid sinus and its surrounding structures as are relevant to performing an endoscopic sphenoidotomy. METHODS Various dimensions of 224 CT images of the sphenoid sinus and surrounding structures from 122 Japanese adult patients were measured using the multiplanar reconstruction technique. RESULTS The mean distance from...
