OBJECTIVE: Recently, in modern neurosurgery, a tendency toward low-traumatic surgical approaches has become clear. To provide a minimal degree of injury to the brain tissue, we have offered microsurgical approaches through a burr hole. METHODS: From February 2016 to November 2017, 200 microsurgical interventions through a single burr hole with a diameter of 14 mm were performed. The age of the patients varied from 16 to 79 years. The female/male ratio was 1.6:1. In 176 cases, the procedure was performed on an intracranial mass lesion in various locations. In the remaining 24 cases, selective amygdalohippocampectomy was performed in patients with hippocampal sclerosis. RESULTS: Various surgical approaches were used, including transcortical in 81 (40.5%), retrosigmoid in 38 (19%), subtemporal in 32 (16%), infratentorial supracerebellar in 25 (12.5%), interhemispheric in 17 (8.5%), telovelar in 5 (2.5%), and eyebrow in 2. The extent of lesion removal was evaluated in 167 patients for whom maximal tumor resection had been planned before surgery. Gross total and near total removal was achieved in 145 patients (87%), subtotal in 15 patients (9%), and partial in 7 patients (4%). The operative time ranged from 35 to 300 minutes (median, 80). The interval to extubation postoperatively varied from 5 minutes to 5 days (median, 70 minutes). Of the 200 patients, 195 (97.5%) were mobilized during the first 3 postoperative days. CONCLUSIONS: Burr hole microsurgery provides the ability to perform successful surgery on patients with the most diverse intracranial pathological features through a smaller opening than that used for keyhole surgery.
