Abstract Background Hearing assessment after middle ear surgery has always been of interest to otologists for one of its major unavoidable and unpredictable complication is hearing loss. As the initial indication for operation is to treat precisely this problem, this complication poses a major dilemma for surgeons. We, thus, aimed to detect the proportion of postoperative worsening of hearing, causes, and risk factors in patients undergoing middle ear surgery. Method This retrospective descriptive study was conducted in the department of otolaryngology of a tertiary care center and data of medical records were retrieved from January 2016 until December 2020. This study included middle ear surgery patients with pre- and postoperative audiometric results. Those patients whose hearing worsened post-operatively (where bone conduction deteriorated > 10 dB) were noted and assessed accordingly. Results The medical records regarding morphological and audiological outcomes of 178 patients were available. We observed auditory degradation after surgery in eight patients (five primary cases and three revision cases), with an overall incidence rate of 4.49%. The mastoidectomy was performed in seven cases, either cortical (n = 5) and modified radical (n = 2). Modified radical mastoidectomy showed the greatest incidence of hearing loss (40%) among all surgical procedures. Except in one case, where sudden, profound loss occurred following otorrhoea on third day, hearing loss was progressive in rest of cases. Conclusion A patient with deteriorating hearing after middle ear surgery must be evaluated properly. There is an increased chance of hearing loss following surgery that involves more ossicular manipulation, drilling, extensive disease clearance, and revision. Utmost care must be taken while operating around ossicles and during disease clearance in key areas. Proper consent should be taken from such patients to avoid future litigations.
