Abstract：Objective To summarize the surgical outcome and experience of the modified pterional transtemporal transtentorial (MPTT) approach for the resection of trigeminal schwannomas. Methods Clinical data of 31 trigeminal schwannomas patients who underwent surgery via MPTT approach were analyzed retrospectively. There were 10 patients with tumors in the middle cranial fossa and 21 with dumbbell-shaped tumors in middle and posterior cranial fossa. Results Gross total resection was achieved in 29 patients, subtotal resection in 1 patient and partial resection in 1. The patients were followed up for 3 to 90 months. The tumor recurred in one patient with giant cyst, who received the second operation. The preoperative symptoms were improved in the remaining patients including the disappearance of dizziness and headache and the improvement of facial numbness and hypesthesia. Conclusions MPTT approach is proper for the resection of trigeminal schwannomas in the middle cranial fossa and dumbbell-shaped tumors in the middle and posterior cranial fossa, and could adequately expose the tumor with an excellent view angle, thus obtaining a high resection rate.
