Abstract

The great auricular sensory nerve action potentials (SNAPs) were recorded in 64 nerves of 32 normal subjects. The mean peak and onset latencies were 1.89±0.21 (mean ±S.D.) and 1.34±0.15 msec, respectively. The latencies were constant independently of increasing in age. The mean amplitude of SNAPs was 22.4±8.93 μv and was significantly smaller when compared to the median nerve SNAPs (p<0.005). There was a linear relationship between the great auricular SNAP amplitude and age. Electrophysiological assessment of the great auricular nerve conduction should be useful both in differentiating between the post-ganglionic and pre-ganglionic lesions in the second and third cervical segments and in evaluating the function of the great auricular nerve itself.
