ABSTRACT
Introduction: The ear is a sensory organ that picks up sound waves, allowing us to hear. Hearing loss in COM can result from TM perforation. It is generally accepted that severity of hearing loss and site of perforation is connected. Nevertheless, there are several contradictory studies addressing hearing loss related to size and site of TM perforation. Hence, this study is done to correlate the size and site and of TM perforation and to assess impact on the types and degree and of hearing loss in patients with COM.
Objective: The objective of the study was to correlate hearing loss with size and site in TM perforation and to assess its impact with types and degree of hearing loss in patients of COM.
Methods: It was a one-year observational study. The study included a total of 113 ears with TM perforation patients of both sex and between group of 18-60 years. Size of TM perforation was measured using Image J software. Site of TM perforation was assessed using Otoendoscopic examination. Each patient underwent PTA and ENT examination.
Results: Hearing loss was more with increased size of perforation. Hearing loss was comparatively more when perforations were located in the Posterosuperior quadrant. There is a significant association with degree hearing loss and of size of perforation. The degree of hearing loss increases with increased size of the perforation.
Conclusion: Thus, the study shows significant correlation between size and site of TM perforation with the types and degree of hearing loss.
