Abstract：
OBJECTIVE: Facial nerve paralysis is the most problematic complication of surgery for parotid tumors. This study aimed to examine the progress of recovery from postoperative transient facial nerve paralysis (POFNP).
METHODS: Participants were 203 patients who developed POFNP after benign parotid surgery. A Kaplan-Meier showed the progress of recovery from paralysis. Factors involved in recovery were examined. For factors for which a significant difference was found, recovery from paralysis was examined over time.
RESULTS: Rates of recovery from paralysis were as follows: 28.6% of patients at 1 month, 58.3% at 3 months, 85.9% at 6 months, and 95.1% at 12 months after surgery. Deep lobe tumors were shown to be significantly associated with delayed recovery from paralysis. The relationship between tumor location and the time of recovery from was that deep lobe tumors had a significantly worse recovery from paralysis at 4 and 5 months after surgery.
CONCLUSIONS: Patients who develop POFNP must be informed about the progress of recovery and factors involved in recovery from paralysis. We believe that the results of the present study are a useful reference to that end.

摘要：
目的：面神经麻痹是腮腺肿瘤手术中最棘手的并发症。本研究旨在探讨术后短暂性面神经麻痹（POFNP）的恢复进展。
方法：受试者为203例腮腺良性手术后出现POFNP的患者。Kaplan-Meier显示了瘫痪恢复的进展。检查了恢复中涉及的因素。对于发现显著差异的因素，随着时间的推移，检查了瘫痪的恢复情况。
结果：瘫痪恢复率如下：28.6%的患者在1个月时，3个月时58.3%，6个月时85.9%，术后12个月为95.1%。研究表明，深叶肿瘤与瘫痪恢复延迟显着相关。肿瘤位置与恢复时间之间的关系是，深叶肿瘤在手术后4个月和5个月的瘫痪恢复明显较差。
结论：发生POFNP的患者必须了解恢复的进展和与瘫痪恢复有关的因素。我们认为，本研究的结果是这方面的有益参考。
