Objective:To summarize and analyze the effect of facial nerve decompression surgery for the treatment of Bell's palsy and Hunt syndrome. Methods:The clinical data of 65 patients with facial nerve palsy who underwent facial nerve decompression in our center from October 2015 to October 2022 were retrospectively analyzed, including 54 patients with Bell's palsy and 11 patients with Hunter syndrome. The degree of facial paralysis（HB grade） was evaluated before surgery, and ENoG, pure tone audiometry, temporal bone CT and other examinations were completed. All patients had facial palsy with HB grade V or above after conservative treatment for at least 1 month, and ENoG decreased by more than 90%. All patients underwent facial nerve decompression surgery through the transmastoid approach within 3 months after onset of symptoms. The recovery effect of facial nerve function after surgery in patients with Bell's palsy and Hunter syndrome was summarized and analyzed. In addition, 15 cases in group A（operated within 30-60 days after onset） and 50 cases in group B（operated within 61-90 days after onset） were grouped according to the course of the disease（the interval between onset of symptoms and surgery） to explore the effect of surgical timing on postoperative effect. Results:There was no significant difference between the two groups of patients with Chi-square test（P=0.54） in 42 patients（77.8%, 42/54） with Bell's palsy and 7 patients（63.6%, 7/11） in patients with Hunter syndrome who recovered to grade Ⅰ-Ⅱ. According to the course of the disease, 10 cases（66.7%, 10/15） in group A recovered to grade Ⅰ-Ⅱ after surgery. In group B, 39 patients（78.0%, 39/50） recovered to grade Ⅰ-Ⅱ after surgery, and there was no statistically significant difference between the two groups by Chi-square test（P=0.58）. Conclusion:Patients with Bell's palsy and Hunter syndrome can achieve good results after facial nerve decompression within 3 months of onset, and there is no significant difference in the surgical effect between the two types of patients.
目的：总结分析面神经减压术治疗贝尔面瘫和亨特综合征的效果。 方法：回顾性分析2015年10月至2022年10月接受面神经减压术治疗的65例面神经麻痹患者的临床资料：贝尔面瘫54例，亨特综合征11例；术前评估患者面瘫程度（HB分级）并完成面神经电图（ENoG）、纯音测听、颞骨CT等检查。所有患者接受手术标准均为保守治疗至少1个月效果不佳，HB分级在Ⅳ级以上，ENoG下降超过90%，并且在发病3个月内接受经乳突入路面神经减压术。总结分析贝尔面瘫和亨特综合征两类患者术后面神经功能恢复效果；并且按病程（从发病到手术的间隔时间）分组：A组（发病30～60 d接受手术）15例，B组（发病61～90 d接受手术）50例，探讨手术时机对术后效果的影响。 结果：贝尔面瘫患者术后恢复至Ⅰ～Ⅱ级42例（77.8%，42/54），亨特综合征患者术后恢复至Ⅰ～Ⅱ级7例（63.6%，7/11），经χ²检验（P=0.54）两类患者比较差异无统计学意义。按病程分组，A组术后恢复至Ⅰ～Ⅱ级10例（66.7%，10/15）；B组术后恢复至Ⅰ～Ⅱ级39例（78.0%，39/50），经χ²检验（P=0.58）2组患者比较差异无统计学意义。 结论：贝尔面瘫和亨特综合征患者在发病3个月内接受面神经减压术均可获得良好效果，且两类患者手术效果无显著差异。.
