Background and Objectives The purpose of this study was to determine the prevalence of bilateral chronic otitis media (BCOM) and the ratio of unilateral or bilateral cholesteatoma in BCOM. Pre- and post-operative hearing were analyzed to see if bilateral balanced hearing were achieved. Subjects and Method A retrospective review was done with a computerized otologic database to identify all patients who underwent surgical treatments for COM between 1998 and 2011, and has a follow up duration for at least 6 months. Comparative analysis between pre- and post-operation hearing was measured by pure tone audiometry and achievement of bilateral balanced hearing was analyzed with ‘The Belfast rule of thumb’. Results Two hundred and eighty-one (14.5%) of 1938 patients suffered from BCOM, and of these, 73 (25.9%) of the patients with BCOM had cholesteatomas in one (12.4%) or both ears (13.5%). When a patient with BCOM is found with cholesteatoma in one ear, the odds of there being cholesteatoma in the other ear was 52.1%. According to ‘The Belfast rule of thumb’, it is considered difficult to achieve successful bilateral hearing gains sufficient for the patients to perceive subjective hearing improvements in BCOM. Conclusion Approximately 15% of the COM patients were found with the disease in both ears, and the odds of a patient with BCOM having cholesteatoma in one ear also having cholesteatoma in the other ear was 53.4%. It was difficult to achieve subjective, successful and balanced bilateral hearing gain with three-dimensional hearing improvements. Korean J Otorhinolaryngol-Head Neck Surg 2014;57(12):821-5
