Aetiology of Traumatic Tympanic Membrane Perforation in Ratnapura

Introduction

Tympanic membrane perforation is a condition as old as the human species. It is a common presentation in an E.N.T. unit and a frequent cause of morbidity.

 

Objectives

The aim of the study is to profile the etiological factors of Traumatic Tympanic Membrane perforation occurring in Ratnapura.

 

Method

A descriptive, prospective serial study was done at General Hospital Ratnapura. We analysed patients with tympanic membrane perforation during the study period of 6 months which started from 1st April 2015.

 

Results

Fifty-two (52) cases of traumatic tympanic perforations were seen. There were 21(40.4%) females and 31(59.6%) males. The mean age of younger patients (<20yrs) was 15years (STD 4) and in adults (>=20yrs) it was 35yrs (STD 9.8). The commonest aetiology was due to blows to the ear (74.3%) and it commonly affects the left ear (80.8%) of the victim. The commonest symptom was hearing impairment (31%). Majority of the affected adults were females (51.4%) and the source of blow was the husband (64.3%).

 

Conclusion and Recommendations

Traumatic Tympanic membrane perforation is a common presentation. Educating school going children and taking steps to change social attitudes against violence especially against women may help to reduce incidence of Traumatic Tympanic membrane perforation.
