Tympanoplasty: Factors Influencing Surgical Outcome

We reviewed the records of 183 patients who had undergone myringoplasty during a six year period at the Asir Central Hospital (ACH). This study was limited to cases of repair of uncomplicated perforation of tympanic membrane that did not require ossiculoplasty or mastoidectomy. One hundred and thirty-four (73.2%) were successful myringoplasty and 78 (75.7%) patients had their hearing improved postoperatively. Various factors liable to influence the success rate such as status of middle ear, size and site of perforations, surgical approach and presence of tympanosclerosis were analyzed. Only status of the middle ear and the presence of tympanosclerosis at the time of surgery were found to have a major effect on the final outcome of surgery.
