The Blood Supply of the Tympanic Membrane

Description : The lateral aspect of the tympanic membrane derives its blood supply from both the circumferential and the manubrial branches of the deep auricular branch of the maxillary artery.

In the normal state, the tympanic membrane appears almost avascular, but after a prolonged examination of the ear, syringing, crying, or in inflammatory conditions, these vessels may become quite prominent.
