title: Residual hemifacial spasm after microvascular decompression: prognostic factors with emphasis on preoperative psychological state.
abstract: Residual hemifacial spasm (HFS) after microvascular decompression (MVD) is common, and the factors associated with residual HFS are still controversial. In the present study, we analyzed the outcome of 212 patients with hemifacial spasm after a single microvascular decompression and evaluated the prognostic factors involved in residual hemifacial spasm. Based on our study, possible prognostic factors included indentation of the root exit zone (REZ), preoperative illness duration, and preoperative psychological state. We suggest that MVD should be performed as early as possible for it may decrease the rate of residual HFS. Preoperative assessment of psychological state in HFS patients is a timely intervention that should be implemented to minimize the residual HFS.
