摘要

Objective

This study aimed to determine the success rate of tympanoplasty, the factors associated with failure rate, and audiometric gains after the surgical procedure in Ethiopia.

Results

There were 82 successful grafts take out of the 92 tympanoplasty procedures with an overall success rate of 89.1%. Females, who had tympanoplasty had 45 (91.8%) successful grafts while 37 (86.0%) successful grafts for male. Of the total tympanoplasties, 50(53.4%) of it were done in the left ear. Ear discharge was found to be a significant predictor of tympanoplasty failure rate [AOR = 9.6, 95% CI (1.1 − 88.8)]. There was a significant gain of air conduction with a p-value of < 0.001 after the tympanoplasty procedure which was about 13 dB mean difference.

Conclusions

In this study, only post-operative ear infection was found to decrease the success rate of tympanoplasty significantly. It also revealed that tympanoplasty improves hearing ability. We recommend a strict application of infection prevention and control strategies, and adequate and comprehensive follow-up of patients including audiometric assessment.
