Background: Tympanic membrane perforations are common cause of hearing loss. This study was designed to analyze the relation between tympanic membrane perforation and conductive hearing loss. Materials and 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. Based on the inclusion and exclusion criteria a total of 100 patients were included in this study. All the patients clinical data was analyzed statistically using paired t-test. Results: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 hearingloss. 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.

Introduction             Chronic otitis media (COM) is a most common and prevalent disease of the middle ear. COM has been defined as a longstanding inflammatory condition of middle ear and mastoid, associated with perforation of the tympanic membrane. Tympanoplasties are common surgeries performed for chronic otitis media in inactive mucosal type. Any otological surgery may involve a menace/ hazard of hearing loss post operatively.             In this study, an attempt was made to correlate, size of tympanic membrane perforation, pure tone audiometry and intra-operative findings in tympanoplasties, results were analysed and conclusion drawn. Materials and Methods Forty patients attending ENT OPD with chronic otitis media (COM), inactive mucosal type, with conductive hearing loss undergoing tympanoplasties who were willing to participate in the study were selected.  Ear was examined pre-operatively to assess the size of perforation and then, pure tone audiometry (PTA) was done to assess the type of hearing loss and its severity. During tympanoplasty, middle ear was inspected for ossicular status and any other pathology was noted. Later, the size of tympanic membrane perforation, pure tone audiometry and intra operative findings were correlated with each other and analysed. Result  In small and medium sized perforation, PTA and intraoperative findings correlated with each other. Whereas, in large and subtotal perforation, there was no correlation. Conclusion             In small and medium sized perforation, middle ear inspection may not be necessary. Whereas, in large and subtotal perforation it is necessary.

<p class="abstract"><strong>Background:</strong> The objective of the study was to evaluate the size and site of tympanic membrane perforation, to assess hearing loss in patients with dry tympanic membrane perforation and to correlate the relationship between degree of conductive hearing loss with the size and site of tympanic membrane perforation.</p><p class="abstract"><strong>Methods:</strong> Study (n=150) done to correlate the site and size of tympanic membrane perforations and conductive hearing loss in cases of inactive tubotympanic COM from October 2013 to December 2015. Size of the tympanic membrane perforation was assessed under microscope using a measuring template. Patients were divided into four groups according to size; based on the site: anterior group, posterior group, combined group and divided in to three groups based on the duration of the disease.  </p><p class="abstract"><strong>Results:</strong> Anterior perforations were most common 74 (49.3%). Hearing loss increased as the size of the perforation increased IV&gt;III&gt;II&gt;I [(46.97±6.59)&gt;(38.69±2.63)&gt;(35.13±2.98)&gt;(27.67±1.85) p&lt;0.0001)]. Statistical significance for hearing loss at combined site (41.37±5.9) was higher compared to Posterior (35.21±4.6, p=0.0001) and Anterior (31.7±5.7, p=0.0001). There was statistically significant difference in hearing loss between all three groups (p=0.0001). Degree of hearing loss increased as the duration of the disease increased.</p><p class="abstract"><strong>Conclusions:</strong> Hearing loss is directly proportional to the size of perforation; more for the posterior quadrant perforations when compared to the anterior quadrant perforations of same size; also, hearing loss increases as the duration of the disease process increases.</p>
