Background: The main aims of surgical treatment of chronic middle ear suppuration are elimination of disease process, reconstruction of hearing mechanism and prevention of complications. Materials and methods: This retrospective study was conducted in the Department of ENT and Head & Neck Surgery, SMGS Hospital, Jammu from February 2018 to February 2020. 80 patients who came for open cavity mastoidectomy were included in this study and all those patients had undergone open cavity mastoidectomy. They were assessed primarily by their complaints and then by cavity examination. Each patient had a follow up upto three months at twice weekly intervals. A borderline healing period of three months (12 weeks) was given for the complete epithelialisation of an open mastoid cavity. Results: 20 patients had postoperative cavity problems. The incidence of postoperative cavity problems in our set up is 25%. 18 had prolonged discharge from mastoid cavity as the main problem (90%). Accumulation of wax in the cavity was present in 5 cases (25%). Vertigo persisting beyond the immediate postoperative period was present in 4 cases (20%). Perichondritis of pinna was found in 1 case (5%). Recurrent cholesteatoma was seen in 3 cases (15%). 2 Cases had postoperative wound infection (10%) .4(20%) cases had high facial ridge, 1(5%) case had stenosis of meatoplasty, 11(55%) cases had tympanic membrane perforation and 4(20%) had postoperative granulations. Conclusion: There should be complete exenteration of disease from the middle ear and mastoid. An adequately lowered facial ridge is an essential step to attain a dry cavity.
