Abstract
Microvascular decompression (MVD) is the standard surgical procedure for patients with medically refractory trigeminal neuralgia (TN). Stereotactic radiosurgery (SRS) has gained increasing popularity as a less invasive technique. We report our institution’s outcome in the surgical treatment of TN (MVD vs. SRS), taking patient’s age and gender into consideration.
We retrospectively reviewed a prospectively collected database of patients undergoing MVD or SRS for type 1 idiopathic TN between 2004 and 2019 at the University of Iowa. Standardized data collection focused on preoperative clinical characteristics and postoperative outcomes including the Barrow Neurological Institute (BNI) Pain Intensity Score.
A total of 111 patients underwent MVD and 103 patients underwent SRS for TN. Patients were younger in the MVD (median, 60 years) than SRS (median, 72 years) group. More females (58%) than males (42%) had TN. Multivariate ordinal regression analysis showed that an outcome of BNI score I–II (P = 0.365) and III (P = 0.736) can be achieved with either MVD or SRS; however, BNI score IV (P = 0.031) and V (P = 0.022) were more associated with SRS. Six percent of patients in the MVD group and 26% in the SRS group developed pain recurrence and required a second operation. Nine of 10 patients who underwent MVD after failed SRS had complete pain relief.
Factoring in patients’ age and gender, both MVD and SRS can achieve a favorable outcome for medically refractory TN, although BNI scores of IV and V were more common with SRS.
