ABSTRACT
Pre and postoperative hearing functions of 30 patients with successful myringoplasties were compared. A preoperative screening examination as well as an audiological evaluation were done. The tympanic cavities were thoroughly explored during the operation. A postoperative clinical and audiological follow-up for 3 months was carried out for ears with successful myringoplasties. Pure tone audiometry, tympanometry, and stapedial reflex were encompassed. A comparison was held between the clinical data and the different audiological measurements. The size and site of the perforation as well as the technique of tympanoplasty affect postoperative compliance but does not affect postoperative air-bone gap and hearing gain. Compliance should not be taken as an absolute criteria to a corresponding wide air-bone gap unless it is associated with an intratympanic pathology. Absence of stapedial reflex can be associated with normal middle ear function and normal sensory neural function
