Abstract
Background: Modified radical mastoidectomy is the mainstay in the treatment of a case of unsafe CSOM. In order to reduce the side effects of an open matoid cavity, many methods to obliterate the cavity have been devised. Aims & Objectives: Cavity obliteration was done to study the efficacy of mastoid cavity obliteration Material and Methods: We carried out cavity obliteration with hydroxyapatite in 20 patients and compared the results with non obliteration. Results: We observed that in addition to reduction in size of cavity, there is better epithelisation and hence faster healing of the mastoid cavity. There is also a significant improvement in hearing status of the patients. Conclusion: Modified Radical Mastoidectomy followed by cavity obliteration with hydroxyapatite granules has numerous advantages compared to leaving the cavity as such.
