Axonal numbers in the greater auricular nerve: is there enough to go round?

Hypothesis: Does the greater auricular nerve (GAN) have an appropriate number of myelinated axons for use as an interposition graft for the facial nerve?

Background: Previous studies have suggested that the GAN has a suitable cross-sectional and fascicular area for use as an interposition graft for the facial nerve. In this study, counts of myelinated axons in the GAN have been undertaken to assess, at a microscopic level, its suitability as such a graft.

Methods: Six GANs were examined, and the total myelinated axonal counts and axonal density per square millimeter of fascicular area were calculated.
