Magnitude of Hearing Loss Concerning the Site of Tympanic Membrane Perforation: A Cross-Sectional Study at a Single Institution in Rawalpindi
Abstract
Objective: To determine the relationship between the site of tympanic membrane perforation and themagnitude of hearing loss.Study Design: Cross-sectional study.Place and Duration of Study: The study was conducted at the Department of ENT, Combined Military Hospital,Rawalpindi, Pakistan from 1st August 2023 to 31st January 2024.Methods: Patients aged between 15 and 60 years who presented to the Ear, Nose and Throat (ENT) outdoordepartment with dry tympanic membrane perforations were included in the study after obtaining informedconsent. Enrollment was done using a purposive sampling technique, irrespective of age and gender. Exclusioncriteria included profound hearing loss, actively discharging middle ears, cholesteatoma, and cognitiveimpairment.The data were collected using a structured departmental proforma. A detailed history and thorough ENTexamination were performed, followed by referral for audiological assessment. SPSS version 20 was used forstatistical analysis, and a two-tailed P-value of <0.001 was considered statistically significant.Results: A total of 61 patients (52.45% males and 47.54% females) participated, with a mean age of 34.70 ±11.80 years. The mean hearing loss for posterior perforation was 26.50 ± 5.61 dB, and for anterior perforation, itwas 23.47 ± 6.96 dB. The cases with multiple quadrant perforations showed a mean hearing loss of 41.15 ± 8.65dB.Conclusion: The study demonstrates a significant relationship between the site of tympanic…
