text: The facial nerve has only a very small cutaneous distribution to the skin of the external auditory canal and over the tympanic membrane, where it overlaps with the small somatic branches of cranial nerves IX, X, and possibly V. Additionally, nerve VII variably supplies small branches to the ear lobe and the mastoid, which overlap with the distributions of the trigeminal nerve and cervical nerves 2 and 3.
