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

Purpose: Perform an analysis of epidemiological, diagnostic and therapeutic aspects of tympanoplasty in Ivory Coast.

Materials and methods: Retro and prospective study over 13 years conducted in the ENT department of Yopougon Teaching Hospital. Our study concerned 104 patients.

Results: 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.

Conclusion: 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.
