Abstract：
OBJECTIVE: To identify clinical and epidemiological characteristics of patients with peripheral facial palsy (PFP) at a tertiary care hospital.
METHODS: This is a retrospective observational study of patients with PFP treated at a tertiary medical center. We gathered demographic data, etiology, laterality, recurrence, recovery, clinical ophthalmology, severity according to the House-Brackmann (HB) scale, electrophysiological tests, medical services attended, medical and surgical treatment.
RESULTS: Two hundred and eighty-three PFP were included, 135 (48%) were men and 148 (52%) were women p = 0.47). All patients had unilateral involvement. The mean age was 54 ± 20 years. The main etiology was idiopathic in 215 (76%) patients. Median recovery time was 7 weeks. Recovery was complete in 190 (67%) patients. One hundred and seventy (84%) patients with idiopathic PFP had complete recovery, versus 30 (16%) patients with non-idiopathic PFP (p < 0.01). The 84% of patients with HB grade II, recovered completely, while with HB grade VI only 17% recovered (p = 0.003). Two hundred and twenty-nine patients (81%) had lagophthalmos. The majority received ocular surface care treatment in 271 (96%) patients and of these 249 (88%) patients received oral corticosteroid therapy. Thirteen patients (5%) required ophthalmologic surgery.
CONCLUSIONS: PFP affects all age ranges, without predilection for sex and unilateral. Its main cause is idiopathic. Recovery is complete in most cases, being more favorable in mild and idiopathic affections. Most only require medical treatment.

摘要：
目的：了解三级医院周围性面神经麻痹（PFP）患者的临床和流行病学特征。
方法：这是一项在三级医疗中心接受治疗的PFP患者的回顾性观察性研究。我们收集了人口统计数据，病因学,偏侧性,复发,recovery,临床眼科，根据House-Brackmann(HB)量表，电生理测试，参加医疗服务，医学和外科治疗。
结果：包括二百八十三个PFP，男性135人（48%），女性148人（52%）（p=0.47）。所有患者均有单侧受累。平均年龄为54±20岁。215例（76％）患者的主要病因是特发性。中位恢复时间为7周。190例（67%）患者完全恢复。一百七十（84％）特发性PFP患者完全恢复，非特发性PFP患者30例(16%)(p<0.01)。84%的患者为HBⅡ级，完全恢复,而HBVI级仅恢复了17%(p=0.003)。二百二十九名患者（81％）患有痛觉。大部分接受眼表护理治疗的有271例（96%）患者，其中249例（88%）患者接受口服皮质类固醇治疗。13例患者（5％）需要眼科手术。
结论：PFP影响所有年龄范围，不偏爱性和单方面。其主要原因是特发性。在大多数情况下，恢复已完成，对轻度和特发性情感更有利。大多数只需要医疗。
