Abstract
Tympanic membrane perforation is a world wide common problem particularly in under developed & developing countries. In the current study 352 patients were studied in a period of 6 months period. The age of the patients were between 2.5 to 86 years old. It wasn’t possible to find any significant difference between men and women. The most common form of perforation was central, and the least form was total. The most common cause of perforation was infection with traumatic manipulations and compression injuries coming after. The average amount of hearing loss was found to be 31.9 db which shows presence of some degrees of ossicular and middle ear malfunction.
