Objective: To evaluate the efficacy of intact bridge mastoidectomy for chronic ear diseases and compare it with canal wall down technique and intact canal wall technique.
Materials and Methods: A prospective and comparative study was done on 120 patients, divided into three equal groups .Patients of chronic supportive otitis media with granulation, cholesteatoma and cholesterol granuloma were taken for study.40 patients were operated by IBM technique,40 patients by CWD technique and 40 patients by ICW technique. Results were compared in terms of air bone gap improvement and success rate.
Results: In our study, in terms of outcome, air bone gap improvement by IBM technique was better than CWD technique, but was comparable to ICW technique. Incidence of recurrence of disease was less than that of ICW technique but was almost equal to CWD technique.
Conclusion: IBM technique is a very good technique in comparison to CWD and ICW technique, as it results in better ABG improvement and recurrence is less.
