Tympanometric measurements after successful myringoplasty

Measurement of middle ear compliance and hearing function after successful myringoplasty was studied. Factors such as perforation site and size were evaluated in relation to postoperative middle ear compliance and hearing function. The relationship between middle ear compliance and perforation site and size was significant. By contrast, the relationship between postoperative compliance and time of follow-up and postoperative hearing gain was not significant. In conclusion, graft affects compliance but not hearing gain. Post- operative middle ear parameters should be interpreted in relation to hearing sensitivity
