This st udy was limited to cases of repair of uncomplicated perforation of tym panic membrane that did not require ossiculoplasty or mastoidectomy. O ne hundred and thirty-four (73.2%) were successful myringoplasty and 7 8 (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.
