Abstract
Transsphenoidal surgery is an effective and safe treatment for most patients with pituitary adenoma and could be considered the first choice therapy in all cases except for prolactinomas responsive to dopamine agonists. It show excellent results with tumors confined to the sella.
The panoramic view offered by the endoscope is a great advantage that makes the surgery much easier and brings the anatomy closer to the surgeon’s eye so that the surgeon can follow the extrasellar part of the tumor with better visualization and he can easy identify the arachnoid membrane and preserve it.
There is no doubt that there is a learning curve for neurosurgeon who is not familiar with the endoscope. This is mostly because the endoscopic techniques require different surgical skills than the microscopic techniques.
The results of this thesis supported by the results of the large series regarding the pituitary adenoma surgery in the literature in that the transsphenoidal surgery is the first treatment of choice for all kinds of pituitary adenoma except the prolactinoma responsive to medical treatment.
The endoscopic assisted pituitary surgery proved to be superior in results over the conventional microscopic surgery in terms of resectability of the tumors, clinical improvement after surgery, the need for postoperative further treatment and convenience related to surgery with comparable rate of complications.
The complications , CSF leak and DI are less than with the conventional microscopic surgery.
this study included 25 patients, with pituitary macroadenomas who underwent complete preoperative clinical assessment and thorough endocrinological and radiological evaluation. The patients were up postoperatively followed up clinically, endocrinologicaly and radiologically.
