[Tympanoplasty: Experience of the ENT department in Yopougon hospital (Ivory Cost)].

Perform an analysis of epidemiological, diagnostic and therapeutic aspects of tympanoplasty in Ivory Coast.Retro and prospective study over 13 years conducted in the ENT department of Yopougon Teaching Hospital. Our study concerned 104 patients.The study population was dominated by young adults with an average age of 30.61 years. Chronic otitis media accounted for 80.76% of past medical history, a condition that was also the main indication (74.04%). Otoscopy pre- and intraoperative found essentially a non-marginal tympanic perforation (74.03%) and preoperative hearing assessment noted a conductive hearing loss in 72% of cases. The retroauricular surgical incision was performed in all patients. Surgical treatment consisted of a tympanoplasty type I in 76.3% of cases. The anatomical results were good in 81% of cases and functionally, 75% of our patients had interaural intensity difference of less than 20 decibels.The tympanoplasty performed in our hospital apparently gives results that are similar to those of western countries to the patients who got a post operative control.
