Electroneurography (ENoG) and clinical staging are currently the methods of choice to indicate prognosis in Bell's palsy, although ENoG is an electrophysiological test not universally available.
Identify other options of prognostic evaluation based upon clinical aspects and minimal electrical stimulation test allowing prognostic measurement in almost any circumstances.
Historic cohort.
Chart review of 1,521 cases of IPFP, analyzing the following clinical aspects: gender, age, paralyzed side, installation mode, previous symptoms, associated symptoms and minimal electrical stimulation test (Hilger test) and its statistical correlation to facial palsy evolution after 6 months.
Data indicated that patients above 60 years old had worse prognosis in comparison with patients under 30 years old. A progressive mode of paralysis installation, absence of previous symptoms, concomitant vertigo and response superior to 3.5 mA at minimum electrical stimulation test were also related to worse prognosis. On the other hand, the absence of concomitant symptoms, diminished tearing and sudden onset were related to better prognosis.
Clinical factors and Hilger's test can accurately indicate the prognosis in cases of Bell's palsy when ENoG is not available.
目前，神经电图（ENoG）和临床分期是预测贝尔面瘫预后的首选方法，尽管ENoG是一种并非普遍可用的电生理检查。
基于临床因素和最小电刺激试验确定其他预后评估方法，以便在几乎任何情况下都能进行预后测量。
历史性队列研究。
对1521例特发性面神经麻痹病例进行病历回顾，分析以下临床因素：性别、年龄、面瘫侧、发病方式、既往症状、伴随症状以及最小电刺激试验（希尔格试验）及其与6个月后面神经麻痹进展的统计相关性。
数据表明，60岁以上患者的预后比30岁以下患者差。渐进性发病方式、无既往症状、伴有眩晕以及最小电刺激试验反应超过3.5 mA也与预后较差有关。另一方面，无伴随症状、流泪减少和突然发病与较好的预后有关。
当无法进行ENoG检查时，临床因素和希尔格试验可准确预测贝尔面瘫的预后。
