INTRODUCTION: Widening of the external auditory canal is canalplasty. It is an intergral part of tympanoplasty, especially in anterior perforations and gives wide surgical access for proper repair. MATERIALS AND METHODS: After elevating tympanomeatal flaps the canal is widened using conical cutting and diamond burrs following which entire tympanic annulus is visible and corresponds to an inverted truncated cone. RESULTS: Canalplasty gives 9 db gain in hearing compared to without canalplasty. CONCLUSION: Canalplasty gives better visualization, better graft placement and better post-operative care.
