Background: Due to human violence, perforation of the tympanic membrane is a frequent occurrence all over the world. The abrupt increase in air pressure in the external auditory canal is the pathophysiology of traumatic tympanic membrane perforation.

Objective: To assess the causes and characteristics of traumatic Tympanic Membrane perforation in a tertiary care hospital
