The House-Brackmann is the most widely accepted system for the clinical assessment of facial nerve function. It is, however, being subjective and discontinuous, prone to interobserver variation. The need for an objective system persists. The Nottingham System is described and compared to the Burres-Fisch system in a study of 29 subjects with varying degrees of facial nerve function, ranging from normal to total paralysis. Within-group component of variance analysis was 7% for the Nottingham System compared to 26% for the Burres-Fisch system. Bland and Altmans' analysis showed the Burres-Fisch system to be biased, overestimating small percentage scores, and underestimating large ones. The Nottingham System proved unbiased. The Nottingham System is recommended as an accurate objective continuous grading system for the rapid assessment of facial nerve function in the clinic.
House-Brackmann是临床评估面神经功能最广泛接受的系统。然而，它具有主观性和不连续性，容易出现观察者间差异。对客观系统的需求依然存在。在一项对29名面神经功能程度各异（从正常到完全麻痹）的受试者的研究中，描述了诺丁汉系统并将其与Burres-Fisch系统进行比较。诺丁汉系统的组内方差分量为7%，而Burres-Fisch系统为26%。Bland和Altman分析表明，Burres-Fisch系统存在偏差，高估了小百分比分数，低估了大百分比分数。事实证明，诺丁汉系统无偏差。推荐诺丁汉系统作为一种准确的客观连续分级系统，用于临床快速评估面神经功能。
