We studied clinical features of 16 cases, diagnosed as sphenoid sinus neoplasma by CT scan, during the seventeen years from 1975 to 1991. These patients showed nasal symtoms in 50%(8/16), diplopia by abducens nerve paralysis in 80%(13/16), blepharoptosis by oculomotor nerve paralysis in 50%(8/16), lack of optesthesia by optic nerve paralysis in 43%(7/16).<BR>We studied the relation between cranial nerve paralysis and the tumor invasion of the sphenoid sinus, ethmoid sinus, nasal cavity, and cavernous sinus. On the other hand, of these cases, six cases (32%) showed epistaxis and 10 cases (62%) showed headache. We suggested that these symptoms are important signs for early diagnosis and differential diagnosis from benign tumor.
