Introduction: treatment of choice for growth hormone-producing hypophysial tumors is surgery. The recurrence percentage is high but, to a great extent, is related to the surgeon´s experience, the surgical technique and the multidisciplinary work. Since 2011, a multidisciplinary team was created to guide the behavior and the follow-up of these patients who would be operated on by using the endoscopic technique based on the neuronavigation. Objective: to describe the results of the growth hormone-producing hypophysial adenomas surgery by using the neuronavigation technique. Methods: a descriptive study that included checking of the medical records of 18 patients diagnosed with growth hormone-producing hypophysial tumors and referred for endoscopic surgical treatment through neuronavigation. The analyzed variables were age, sex, tolerance test for glucose to measure growth hormone before and 7 days after surgery, the characteristics of the tumor, the postsurgical complications and the progress. Results: of this group of 18 patients, 66.6 % were males 33.4 % had tumors growing into the floor of the Turkish saddle and the postsurgical complications were minimal: 16.7 % presented with transient diabetes insipidus and the same percentage had a cerebrospinal fluid fistula. Biochemical remission was detected in 55 % of patients one week after the surgery. Conclusions: growth hormone-producing hypophysial tumors surgery using the endoscopic technique with neuronavigator provides advantages for patients, with satisfactory recovery from the clinical and biochemical viewpoint as well as low frequency of complications.
