Abstract

To evaluate hearing results following canal wall down mastoidectomy with ossicular reconstruction for Chronic Suppurative Otitis Media of Active Squamosal variety & evaluate various factors related to surgery impacting hearing results. This prospective study involves 40 patients of active squamosal variety of chronic otitis media who attended ENT OPD and underwent canal wall down mastoidectomy with ossiculoplasty during the period from November 2014 to October 2015. All the patients were subjected to pre and 3 months post-op hearing assessment. Based on the hearing outcome, we expressed our study results into two groups, those with statistically significant improvement after surgery (T1) and those whose hearing got worsened or remained the same (T2). The mean post operative hearing gain of patients was 5.25 ± 7.30 dB, The median post-op hearing gain was 5.20 dB. Mean pre-operative hearing loss (AB gap) was 41.28 dB. Mean post-operative hearing loss (AB gap) was 36.24 with the average 3 months post-operative hearing gain was 5.2 dB, which reflects a definite improvement. There is a statistically significant hearing improvement (with an average of 5.2 dB AB gap closure) following Canal Wall Down Mastoidectomy with ossiculoplasty as established in the study.
