Morphometry in greater auricular nerve
In 3 biopsy specimens of greater auricular nerve (GAN) the density of myelinated fibers was almost twice as high as in 10 control specimens from sural nerves (SN). We found an increase of smaller and a decrease of larger fibers in GAN compared to SN. Unmyelinated fibers in GAN revealed higher densities, a larger amount of smaller fibers, and an increased ratio axon to Schwann cell complex when compared with 2 SN. It is concluded that these preliminary results reflect natural conditions in short sensory nerves supplying highly sensitive regions.
