Abstract
Objective To analyze the value of blink reflex (BR) and facial nerve conduction (FMC) in assessing prognosis of idiopathic facial nerve palsy. Methods Ninety patients with idiopathic facial paralysis admitted to Zhengzhou People’s Hospital from December 2017 to December 2018 were randomly selected. All patients underwent BR and FMC tests, and their waveform detection results were analyzed. Results The no-wave rates of R1, R2 and R2’of the affected side in the 90 patients were 41.11%, 30.00% and 31.76%, respectively, which were higher than those of the healthy side (P<0.05). The latency of R1, R2 and R2’of the affected side were longer than that of the healthy side. The M wave latency of different parts of the affected side was longer than that of the healthy side (P<0.05), and the M wave decreased by <50%, 50%-80%, ≥80% of the recovery time ratio was compared, the difference was statistically significant (P<0.05). Conclusions BR can be used as an objective diagnostic criterion for idiopathic facial nerve palsy, and FMC can be used as a prognostic evaluation criterion for idiopathic facial nerve palsy. Key words: Blink reflex; Facial nerve conduction; Idiopathic facial paralysis
