Solitary abducens palsy secondary to isolated sphenoid sinus disease (ISSD) is rare and early management is important. There is no report regarding the results of endoscopic sinus surgery (ESS) for prolonged abducens palsy due to ISSD. We present four cases of ISSD with solitary abducens palsy that received ESS from 1995 through 2000. The interval between onset of diplopia and ESS was longer th...

BACKGROUND Currently, there is no uniform consensus regarding the appropriate staging for invasion of the paranasal sinuses in nasopharyngeal carcinoma (NPC). In the current AJCC staging system for NPC, paranasal sinus invasion is defined within the T3 classification. However, according to the Chinese 2008 staging system, which is also widely used in the regions where NPC is endemic in China, p...

PURPOSE To test the hypothesis that in patient with sunken eyes, sagging brain syndrome, bone remodeling is not limited to the orbits. Volumetric analysis of the sphenoid sinus is performed in this study. METHODS In this university-based retrospective case-control study, the dimensions of the sphenoid sinus were measured in four patients (2 males, 2 females; mean age 26.3 years, range 16-38 y...

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...

PURPOSE To delineate the relationship between the optic nerves and the posterior paranasal sinuses using CT data. METHODS Direct coronal sinus CT scans of 150 consecutive patients with chronic inflammatory sinus disease were reviewed by two radiologists. Axial oblique reconstructions along the course of the optic nerve were obtained for the first 100 patients. The direct relationship between ...

Meningiomas are slow-growing benign lesions that constitute ∼ 25% of primary intracranial tumours. Extracranial meningioma of the sphenoid sinus is extremely rare and may arise from ectopic arachnoid nests left behind during embryonic development. We present the case of a 61-year-old woman with left oculomotor nerve paralysis. Magnetic resonance imaging (MRI) revealed a 43 × 31 × 33 mm mass in ...

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.

OBJECTIVE To review and report diseases of the sphenoid sinus from the literature and from a university hospital. METHODS Inpatients' data were retrospectively gathered and reviewed from January 2006 to June 2016. Clinical data, imaging, organisms, and pathological reports were collected. Pathology was divided into infection/inflammation, tumor, and miscellaneous. A literature review was perf...

Sinus pneumatization is a complex variable process that begins in early life and continues for many years. We present a case of a 6-year-old boy with progressive headaches and neurologic symptoms suggestive of intracranial pathology. The presence of enhancing tissue within the sphenoid sinus created a diagnostic dilemma which leads to a transsphenoidal biopsy. Knowledge of imaging characteristi...
