Abstract：Objective:To explore the microsurgical skill and the curative effect of treatment of dumbbell trigeminal neurinoma under frontotemporal-subtemporal intradual approach. Methods:From January 2009 to September 2012, the clinical data of 15 patients with dumbbell trigeminal neurinoma received microsurgery via frontotemporal -subtemporal intradual approach were analyzed.Results:Total resection was achieved in 13 cases(86.67%),subtotal resection was performed in the other 2 cases with small portion tumor remained in the cavernous sinuses. No operative death. The transient oculomotor never paralysis occurred in 1 case postoperativly.The abducenct nerve paralysis happened in another case. They both recovered after operation. 13 patients were followed up for 4-36 months. The cases of total resection had no recurrences. The case of subtotal resection with γ-knife treatment after operation was stable.Conclusions:The best microsurgical approach for the removal of dumbbell trigeminal neurinoma is frontotemporal-subtemporal intradual approach.
