Abstract

Background: Tympanic membrane perforations are common cause of hearing loss. This
study was designed to analyze the relation between tympanic membrane perforation
and hearing loss.
Methods: In this prospective study, patients with dry tympanic membrane perforations
of safe type were included. The patients were divided into groups in according to size,
site and duration of perforation
Results: 49 patients with 70 dry tympanic membrane perforations were studied. Data
was analyzed statistically using paired t-test. Hearing loss increased as the size of
perforation increased. Posterior quadrant perforations were associated with more
hearing loss as compared to anterior quadrant perforations. Also duration of disease
was in linear relation with mean hearing loss.
Conclusions: The degree of conductive hearing loss as a result of tympanic membrane
perforation would be expected with the size, site and duration of perforation.
