BackgroundThe tuberculum sellae is a relatively common location for meningiomas. We assessed our experience with the use of transcranial resection, which, although criticized for its more invasive nature compared with endonasal approaches, may be the ideal approach in selected patients with tuberculum sellae meningiomas (TSMs).MethodsWe retrospectively reviewed the charts of patients with TSMs treated by frontotemporal or bifrontal open cranial resection. Clinical, radiographic, and surgical variables were analyzed.ResultsForty-nine patients with a TSM treated by frontotemporal or bifrontal open cranial resection were identified. The mean patient age was 53.2 ± 14.0 years, and the mean duration of follow-up was 42.3 ± 45.4 months. The mean tumor volume was 12.4 ± 18.0 cm3. Optic canal invasion was seen in 46.9% of the patients, and 91.8% presented with visual deficits. Gross total resection (GTR) was achieved in 42 patients (85.7%), and near-total resection was performed in 7 patients (14.3%). Postoperatively, visual outcomes improved in 17 patients (34.7%), remained stable in 22 (44.9%), were intact in 6 (12.2%), and worsened in 1 (2.0%). Good outcome (Glasgow Outcome Scale [GOS] ≥4) was achieved by 46 of 49 patients (93%) at discharge and by 39 of 41 patients (95.1%) at 6 months. A total of 16 manageable and self-limiting complications occurred in 16 patients.ConclusionsIn most patients undergoing a frontotemporal approach, a GTR/Simpson grade I resection with manageable and self-limiting surgical complications, a good 6-month GOS in most patients, and improved to stable vision were seen at follow-up. Various treatment approaches can be considered for TSM resection, but the ability to decompress the optic canal and achieve a GTR makes the frontotemporal approach attractive in many cases.Copyright © 2017 Elsevier Inc.
