Introduction: Chronic otitis media is relatively common and potentially dangerous disease of the ear. It is often characterized by cholesteatoma that causes local destruction and osseous erosion leading to complications. Its management is mainly surgical, mostly a canal wall up and down tympanomastoid surgery. High resolution computed tomography (HRCT) is the imaging modality of choice for evaluation of middle ear structures and pathology. The aim of this study is to identify causes of failure and its management with special reference to CT scan. Aims: Evaluation of different causes of revision tympanomastoid surgery, assessment of their outcome, and ascertaining the possible measures to prevent further recurrence. Materials and Methods: This Prospective descriptive study conducted at department of ENT, IPGMER & SSKM Hospital, Kolkata from 1year&6 months (April, 2020 to September, 2021). Result: 30 (60.0%) patients had Modified Radical Mastoidectomy Surgery and 20 (40.0%) patients had Radical Mastoidectomy Surgery. 41 (82.0%) patients had Cavity obliteration Palva flap. 23 (46.0%) patients had Cavity obliteration Bone dust. 26 (52.0%) patients had Cavity obliteration Cartilage. 41 (82.0%) patients had Adequate in Conchomeatoplasty Size Post-operative findings 1 Month. A significant improvement in mean air conduction level, mean bone conduction level, and mean air-bone gap (ABG) was found postoperatively (p < 0.05). For all types of ossicular chain reconstruction, a significant improvement in mean Pure Tone Average was observed (p < 0.05).Conclusion: A revision canal wall down surgery, if performed successfully following all the basic principles of tympanomastoid surgery, can help achieve a safe and dry ear and can significantly improve the subjective well-being of the patients.
