This study was undertaken to assess the outcome of canal wall window tympanomastoidectomy in chronic suppurative otitis media in a tertiary care centre of central India. A total of 50 patients were taken for this study in which the youngest patient was 13-year-old male and oldest 55-year female. Maximum patients were in between age group 10 to 20 years, 20 (40%) patients and minimum 03 (6%) between age group 51 to 60 year. The study mainly emphasized on: To study the clinical profile of the cases of chronic suppurative otitis media, to study the hearing outcome after 3 months of Canal wall window tympanomastoidectomy technique, to study the post-operative condition of ear after 3 months whether dry or wet and to study the post-operative follow up of cases to assess the graft uptake. Average PTA & ABG improvement of different tympanoplasty was also calculated in our study in which Type I tympanoplasty had 12.20dB gain, Type II of 10.50 and Type III of 10.31dB.An overall average improvement in all patients with tympanoplasty was 11.00dB.At the end of the study 100% dry ears were achieved. The technique of canal wall window tympanomastoidectomy involves formation of a window in the outer attic wall to look at the disease extent which was then closed by a snuggly fitting cartilage.It is a novel technique & without compromising the structural integrity in case of a limited disease which is only extending till attic and aditus good anatomical and hearing results could be gained.
