OBJECTIVES/HYPOTHESIS The goal of this study was to present a classification based on the degree of pneumatization of the sphenoid sinus in the coronal plane that can be used to instruct preoperative planning for endoscopic endonasal surgery (EES). STUDY DESIGN Observational anatomical study. METHODS The geometry of sphenoid sinus pneumatization was characterized (n = 204 hemisinus) on high...

A unique case of IgG4(+) sclerosing disease was diagnosed in the sphenoid sinus, a previously unreported location, and was treated in a novel manner. This study describes the clinical presentation and management of IgG4 sclerosing disease in the paranasal sinuses. A retrospective case review and review of the medical literature were performed. A 38-year-old woman with a 2-year history of consta...

A 40-year-old male presented with a single generalized tonic-clonic seizure. MRI revealed an enhancing, dural-based, left lateral sphenoid wing lesion suggestive of a meningioma. At microsurgical excision, the lesion was firm and relatively avascular. The histopathological report revealed S-100 positive histiocytic proliferation with lymphophagocytosis (emperipolesis) characteristic of the Rosa...

OBJECTIVE The purpose of this study was to present the morphometry and pneumatization of the sphenoid sinus in detail for the neurosurgeon for transnasal approach to the hypophyseal tumors and especially for functional endoscopic sinus surgery. METHODS One hundred and eighty midsagittal magnetic resonance images, 48 bones and 29 hemi-sectioned cadaveric heads obtained from Ege University, Fac...

A large Rathke's cyst was marsupialized into the sphenoid sinus of a 45-year old woman who presented with headache, polydipsia, cessation of menses and diplopia. A brief review of cases is presented.

A concha non-pneumatized sphenoid is considered to be a contraindication for the transsphenoidal resection of a pituitary adenoma. Specifically, this anatomical variation makes it difficult to approach the sella turcica. However, in this report, an intra-operative navigational system was used as a guide to access the sella through the sphenoid sinus. This procedure was found to be both reasonab...

Anatomically the cavernous sinus is closely related to the sphenoid sinus and the nasopharynx. Sphenoid sinusitis, as demonstrated in the case can affect the nerves which are contained within it. Apart from the sinus, a direct extension from a nasopharyngeal lesion is commonly encountered to cause diplopia, owing to the sixth nerve involvement. The provisional diagnosis should be a nasopharynge...

The lateral pterygoid muscle (LPM) is intimately related with the temporomandibular joint (TMJ), playing an important role in its physiology. This makes it of interest to researchers who investigate disorders. literature indicates that anatomical variations exist insertion superior fascicle LPM. Imaging and cadaver studies have revealed LPM may present accessory fascicle. study object was carry...
