Canalplasty in Revision Radical Cavity Surgery Using A Meatal T- Skin Flap Technique.

Background: In literature no technique of canalplasty in revision radical cavity surgery has been reported. Yet, inadequate canalplasty is a known contributing factor in troublesome cavities and should be addressed when necessary. Methods: Retrospective cohort analysis of patients undergoing revision radical cavity surgery in which a canalplasty was indicated. All received a canalplasty using a skin flap technique which enables maximal preservation of the delicate epithelial lining of the osseous external auditory canal (OEAC). Results: The described canalplasty technique resulted in quick re-epithelialization (median 8.9 weeks) and dry ears. Only one minor complication was seen. Conclusions: We describe a canalplasty technique that can be used in revision radical cavity surgery and show it is safe and effective. This technique can easily be combined with radical cavity obliteration
