BACKGROUND: Chronic Suppurative Otitis Media (CSOM) is an important cause of preventable hearing loss, particularly in the developing world. Tympanoplasty is a procedure to eradicate the disease in middle ear and to reconstruct hearing mechanism. Pure tone audiometry is an efficient, simple and economic tool to assess the level of postoperative hearing gain.
