Comparison of surgical results between 'atticosinuplasty' and canal wall up mastoidectomy for early-stage cholesteatoma

We devised a surgical technique called 'atticosinuplasty' (AS) for the treatment of early-stage cholesteatoma.This study analyzed the adequacy and applicability of AS compared to canal wall-up mastoidectomy (CWU) in patients treated for early-stage cholesteatoma.A total of 187 patients with either AS (Hearing gain was significant in the AS group (AS is a surgical technique worth trying in patients with early stage of attic/sinus cholesteatoma in terms of the rate of recurrence and hearing improvement.
