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.
微血管减压术（MVD）后残留的半面痉挛（HFS）很常见，与残留HFS相关的因素仍存在争议。在本研究中，我们分析了212例单次微血管减压术后半面痉挛患者的结局，并评估了残留半面痉挛的预后因素。根据我们的研究，可能的预后因素包括神经根出口区（REZ）的压痕、术前病程和术前心理状态。我们建议应尽早进行MVD，因为这可能会降低残留HFS的发生率。对HFS患者进行术前心理状态评估是一种及时的干预措施，应予以实施以尽量减少残留HFS。
