A Comparative Study of Results of Canal Wall Up & Canal Wall down Mastoidectomy as a Surgical Treatment for Cholesteatoma

Abstract

Background: The aim of this study is to compare the results of canal wall up and canal wall down mastoidectomy as a surgical treatment for cholesteatoma. Method: This study was a comparative prospective study carried out in the department of otorhinolaryngology. Results & Conclusion:Hearing results in CWU mastoidectomy were better than in CWD mastoidectomy. With canal wall down technique, the rate of developing complications (persistent ear discharge) was significantly higher when compared with those in canal wall up technique. Other complications ie; perichondritis, wound dehiscence, facial nerve palsy were nil in either group. Recurrence or residual disease was not reported in our cases which may be due to short period of follow up (3 months).
