ABSTRACT: Current tendency is towards minimally invasive surgical approaches that offer short-term recovery and short hospital stays, reducing the costs of treatment. In cranial neurosurgery, minimally invasive surgery is based on the Key-hole concept, that is, small surgical incision that allow an approach to the lesion using natural microsurgical corridors at the subarachnoid space. The technique that we present in this paper may be carried out with basic surgical equipment and instruments, and do not depend on sophisticated technology. In this article, we present our experience in 250 patients with the technique of key-hole surgery of the cerebelopontine angle. We had excellent results that were similar to those reported in the literature, since we had a low postoperative morbidity, fast recovery, fast recovery, reduced offers the advantage of reduced costs for both patients and institutions.
