Abstract EN
To analyze the value of facial nerve antidromic evoked potentials (FNAEPs) in predicting recovery from Bell palsy.
Study Design.
Retrospective study using electrodiagnostic data and medical chart review.
Methods.
A series of 46 patients with unilateral Bell palsy treated were included.
According to taste test, 26 cases were associated with taste disorder (Group 1) and 20 cases were not (Group 2).
Facial function was established clinically by the Stennert system after monthly follow-up.
The result was evaluated with clinical recovery rate (CRR) and FNAEP.
FNAEPs were recorded at the posterior wall of the external auditory meatus of both sides.
Results.
Mean CRR of Group 1 and Group 2 was 61.63% and 75.50%.
We discovered a statistical difference between two groups and also in the amplitude difference (AD) of FNAEP.
Mean ± SD of AD was −6.96% ± 12.66% in patients with excellent result, −27.67% ± 27.70% with good result, and −66.05% ± 31.76% with poor result.
Conclusions.
FNAEP should be monitored in patients with intratemporal facial palsy at the early stage.
FNAEP at posterior wall of external auditory meatus was sensitive to detect signs of taste disorder.
There was close relativity between FNAEPs and facial nerve recovery.
