Myringoplasty results in a district hospital in Botswana.

This was a prospective study to determine the success rate of myringoplasty in a low-resource setting. Myringoplasty was performed on 85 patients and follow-up done for 6 months in order to determine the incidence of closure of the repaired tympanic membrane. The eardrum closure rate at 3 months was 88% and at 6 months 84%. There was a 62% positive change of more than 10 dB in the pure tone averages of air conduction at frequencies 500, 1000 and 2000 Hz and a 24% improvement of less than 10 dB. This compares favourably with results from other studies.
