• Onthe outer surface of tympanic membrane, the anteroinferior part is supplied by the auriculotemporal nerve, and the posterosuperior part by the auricular branch of the vagus nerve.
• On the inner surface, it is supplied by the tympanic branch of the glassopharyngeal nerve through tympanic plexus.
• The auricle and external meatus are supplied by branches of the Vth, IXth and Xth cranial nerves. The medial or posterior surface of the auricle is supplied by fibres of the great auricular nerve (C2 and C3) and the lesser occipital nerve (C2).
