AbstractThis study looked at the incidence of sensorineural hearing loss in the 4-8 kHz range in patients with unilateral tympanic membrane perforations from minor trauma who presented to the department in the past year. Eleven patients conformed to our inclusion criteria, one was lost to follow-up. Perforation was present in all patients in the pars tensa and no treatment was required in nine patients. The mean sensorineural hearing loss at 4,6 and 8 kHz was 28.2 dB on initial examination and 14.6 dB by Day 30. All 11 patients had normal hearing in the contra-lateral ear (mean 13.5 dB). In this group of patients with a tympanic membrane perforation from minor trauma the conductive hearing loss was accompanied by a significant (P = 0.001) but reversible high frequency sensorineural deafness.
