				        	Objective  To study the clinical features and therapeutic effects of pituitary adenomas in elderly patients.   Methods  The clinical materials including main clinical manifestations, diagnostic methods and outcome of treatments of 49 elderly patients with the pituitary adenomas from 1987 to1998 were analyzed retrospectively.   Results  It was showed from the data that the average duration of illness was 4  4 years; and 46(93  8%) cases were with visual deterioration, 20 (40  8%) with headache, and 16(32  7%) with endocrine abnormality. The diameter of tumors was more than 3 cm in 25 (51  0%), and the non  functioning adenomas were found in 27 (55  1%). Operation was undergone through trans  sphenoidal (61  2%), subfrontal (32  7%) and extensive subfrontal extradural approaches(6  1%), respectively. Among the 49 cases, tumor was totally or subtotally removed in 38 cases (77  6%), large partially or partially removed in 11 cases (22  4%). The results of operation through the trans  sphenoidal approach were superior to other routes   All patients were long  term followed  up for an average of 50  5 months. Visual disturbances were improved in 27 of 46(58  7%). A total of 43 patients could live by themselves   Tumor disappearance was observed in 30 cases and recurrence in five cases. Five cases showed no changes in tumor size. 28 cases underwent radiotherapy after surgery and the occurrence rate of hypopituitarism after radiotherapy turned to be 50%. Total tumor control rate was calculated as 93%.   Conclusions  Macroadenomas and non  functional pituitary adenomas happened most frequently in elderly patients and the main clinical symptoms was visual deterioration. Trans  sphenoidal route for microsurgery was believed to be the first choice of operation. Tumor recurrence can be controlled or delayed by postoperative radiotherapy, but severe complication of the visual injury and pituitary dysfunction should be paid much attention.
