Traumatic Tympanic Membrane Perforation in Lokoja, Nigeria: A Review of 43 Cases
Abstract Background: The tympanic membrane main function is the conduction of sound waves for effective hearing hence its perforation almost always results in initial hearing impairment of a reasonable degree. Objectives: To identify common causes, clinical presentation and management outcome of a perforated tympanic membrane. Methods: This is a three year (January 2013-December 2015) prospective hospital base study carried out in the ENT Outpatient clinic of the Federal Medical Centre, Lokoja, Nigeria. Patients were recruited by convenience sampling method after a clinical diagnosis of traumatic tympanic membrane perforation. All patients were made to have PTA for their hearing assessment during and after treatment. Results: A total of 49 patients were recruited but 6 were lost to follow up, the remaining 43 were 24 males and 19 females with a male to female ratio of 1.26:1. Age range was from 2-80years and the modal age group was 11-20years. Ear cleaning and scratching with pointed objects was the commonest cause of traumatic tympanic membrane perforation followed by slapping from assault. Pain was the most common symptom at presentation followed by hearing loss. Spontaneous healing of the membrane occurred in 6 weeks in 34.9% of the patients and with complete restoration of hearing in 96%.
