Objective To discuss the value of the motor evoked potential latency and amplitude of facial nerve in the diagnosis of Bell palsy. Methods Motor evoked potentials of facial nerve were measured on both injured and uninjured sides in 65 patients with Bell palsy within 10 days after the attack;M wave latency and amplitude changes of the 2 sides were compared and the correlation between M wave latency and the amplitude was analyzed. Results The M wave latency of the zygomatic branch of facial nerve on uninjured side and on injured side was(1.71 ±0.06)ms vs.(1.86 ±0.05)ms(P﹥0.05),respectively,while the M wave amplitude was(4.55±0.10)μVvs.(3.40±0.20)μV(P﹤0.01),respectively;theMwaveamplitudeofbuccalbranchesonthe2sideswas (1.92±0.08)msvs.(2.17±0.09)ms(P﹤0.05),respectively,whiletheamplitudewas(3.78± ±0.24)μVvs.(2.93±0.24)μV(P﹤0. 05),respectively. The analysis of the correlation between M wave latency and the amplitude showed that the r value of the zygomatic branch on the injured side was -0. 369(P﹤0. 01),while that on the uninjured side was -0. 472(P﹤0. 01);the r value of the buccal branches on the injured side was -0. 486(P﹤0. 01),while that on the uninjured side was -0. 445(P﹤0. 01). Conclusions The decreased M wave amplitude of facial nerve in patients with Bell palsy is more significant than the prolonged latency for the diagnosis.
