[Clinical, etiologic and therapeutic aspects of chronic sphenoid opacities]

A series of 23 patients with sphenoid disease were seen between 1992 and 1997. The most common symptom was headache. This headache was found to be nonspecific. Cranial nerve abnormalities were found in two patients. The different types of radiolographic images were analyzed, and compared with the surgical diagnosis. Twenty-one patients underwent surgical exploration by intranasal endoscopic sphenoidotomy. This approach allowed drainage and inspection of the sinus.
