The incidence of Bell's palsy is significantly higher during the last trimester of pregnancy and the puerperium. Suggested explanations for this association include fluid retention, hypertension, compromise of the vasa nervorum, infection (particularly with herpes simplex virus), and an autoimmune process. The diagnosis is confirmed by identifying lower motor neurone paralysis and excluding secondary causes for the symptom complex. The majority of cases resolve spontaneously. Recovery may be delayed or incomplete in older patients and those with recurrent episodes or severe initial symptoms. The role of diuretics, steroids, or surgical decompression in treatment of pregnancy-related cases of Bell's palsy has not been well studied.
贝尔面瘫在妊娠晚期和产褥期的发病率显著更高。对于这种关联的推测性解释包括液体潴留、高血压、神经血管受损、感染（尤其是单纯疱疹病毒感染）以及自身免疫过程。通过识别下运动神经元麻痹并排除该症状复合体的继发原因来确诊。大多数病例可自发缓解。老年患者以及有复发发作或严重初始症状的患者恢复可能延迟或不完全。利尿剂、类固醇或手术减压在妊娠相关贝尔面瘫病例治疗中的作用尚未得到充分研究。
