For a great number of pitituary tumors surgery is the first-line treatment and the microsurgical transsphenoidal approach is the most used. At present, it is performed by microscopic and endoscopic way. Recently, the endoscopic transnasal approach has emerged as an option under development that could predominate in a near future. The aim of the present paper was to evaluate by analyzing the results if it was possible to perform in our setting the endoscopic transsphenoidal transnasal approach for the lesions of the sellar region with surgical results similar at least to those obtained with the traditional microsurgical method. A limited strictly controlled and prospective cohort research of 10 patients selected according to the inclusion criteria that underwent transnasal endoscopic surgery between August 2002 and August 2003 at the Neurosurgery service of “Hermanos Ameijeiras” Hospital, was conducted. 6 cases with hypophyseal macroadenomas were operated on (3 GH-releasing, 1 PRL-secreting and 2 non-releasing hypophyseal macroadenomas). The other 4 were diagnosed LCR fistula through the sellar floor. Total exeresis of the tumor was performed in 5 of the 6 macroadenomas, whereas subtotal exeresis was attained in the other one. Rhinorrhea disappeared in 2 patients with LCR fistula and it was maintained in the other 2. Of the complications observed in 30 % of the cases, only in one (10 %), they were beyond the transoperative. It was concluded that the results obtained by using the endoscopic transnasal method make the procedure in our setting safe enough to justify its implementation and to carry out further randomized and controlled studies searching for more consistent information in relation to the real value of the technique at this level of development of the hypophyseal surgery.
