Abstract
Compound muscle action potentials
were recorded bilaterally from alae nasi muscles following
stimulation of facial nerve in 45 normal subjects in the age
group of 20–30 years. Latency, amplitude and total duration
of the compound muscle action potential were compared on both
sides. A significant positive correlation between the three
parameters with the highest for the amplitude was observed.
Therefore it is suggested that amplitude is a better parameter
for comparison while testing for side to side facial nerve
integrity.
