  • Abstract
  • Look Inside

 To estimate the incidence of the nervous prominence in the sphenoid sinus, computed tomographic study was carried out on 50 patients with suspicious lesions arised from the intracranial cavity and paranasal sinus. In the present series, the pterygoid canal was protruded into the sphenoid sinus, causing a pronounced elevation in 20% and slight one in 14%. The foramen rotundum was also observed as an elevation in 42%, and the condition was pronounced in 40%. In most of these cases the pterygoid elevation was also present. The optic canal showed a pronounced elevation in 18%. Moreover, projection produced by the superior orbital fissure was observed in 33%, and the elevation was pronounced in 20%.

 These results suggested that CT can be the definite imaging method in diagnosis of the nervous prominence in the sphenoid sinus, and can provide the valuable informations for evaluation of the sphenoid sinus pathology.
