BACKGROUND Chronic Suppurative Otitis Media (CSOM) is considered to be a slowly progressive destructive disease of the middle ear. It is the most commonly encountered middle ear pathology, which disrupts the normal anatomy and physiological functioning of the ear. Otoscopic evaluation is sufficient to establish the diagnosis of the disease; however, its extent can be determined only on the basis of a High Resolution Computed Tomography (HRCT) of the temporal bone. While the most common presentation of CSOM is a discharging ear. Its complications may be masked by the disease itself, thereby giving a false presentation of a limited extent. HRCT temporal bone can help quantify the extent of the disease and hence prioritise the patients who warrant an urgent management. The aim of this study is to establish the importance of HRCT temporal bone in a patient with unsafe CSOM, even in absence of clinical suspicion of ongoing complication to improve the surgical outcome. MATERIALS AND METHODS This study has been conducted on 50 patients who have presented to the ENT OPD at RGMC, Kalwa. RESULTS Out of 50 patients who presented with complications, 20 patients (40%) did not have any history suggestive of impending complications. The HRCT temporal bone helped in establishing the presence of these complications and allowing for prompt treatment. CONCLUSION It was found that presence of HRCT helps in determining lurking complications and thus helps in deciding the urgency with which tympanomastoidectomy surgery needs to be performed.
