Descriptive statistics were obtained regarding demographics, primary and revision surgery success rates, hearing status pre\u2010 and postsurgery, and frequency of ossicular reconstruction.

For successful primary tympanoplasty, the mean improvement in pure tone average was 11.7 \u00b1 12.1\u00a0dB. Ossiculoplasty was performed in 9.1% (32 of 352) of cases. There was no significant relationship between successful perforation closure and perforation size, perforation character, or time between injury and surgery.
