Abstract
Pituitary tumor of 11 patients were excised via the endonasal-transsphenoidal approach. Their age ranged from 21 to 64 years, and the disease was non-functional in 4 cases, GHoma in 4, PRLoma in 2 and cystic mass in one. As complications, arterial hemorrhage occurred in one case, cerebrospinal fluid in one and dysosmia in one, but good sinus morphology was able to be retained in all cases. Although surgical manipulation and control of hemorrhage are troublesome, its invasiveness is low, and postoperative observation of wound and reoperation are easy. If this approach is employed under cooperation between an otorhinologist with skilled endoscopic manipulation and neurosurgeon, this approach is thought to be an effective surgical method for pituitary tumor.
