Abstract
AbstractObjectiveThis study aimed to evaluate the effect of size, location and shape of tympanic membrane perforations on hearing levels of a large study group treated in a tertiary referral centre.MethodMedical data of 458 patients with tympanic membrane perforations were evaluated.ResultsA total of 336 patients had normal middle-ear findings during the surgical procedures. There was a significant difference in terms of mean pure tone average and air–bone gap values between posterior-inferior and anterior-inferior perforations (p = 0.005 and p = 0.044, respectively). The mean air–bone gap value of kidney-shaped perforations was significantly higher. Posterior-superior and posterior perforations were significant indicators for ossicular chain defects (p < 0.001; odds ratio, 14.2 and p = 0.004; odds ratio, 3.4, respectively).ConclusionPerforations located in the posterior-inferior quadrant caused the greatest hearing loss. The difference between posterior-inferior and anterior-superior or inferior perforations was statistically significant. Posterior perforations had a significant relationship with ossicular chain pathologies. Kidney-shaped perforations caused higher pure tone average and air–bone gap values than annular, elliptical or pinpoint perforations.
