Modified canal wall-up mastoidectomy with mastoid obliteration for severe chronic otitis media.
Mastoid tympanoplasty with a canal wall-up technique provides better conditions for a healthy skin lining than canal wall-down techniques. The formation of retraction pockets in residual pneumatized cavities is however a major cause of cholesteatoma recurrence with canal wall-up techniques. We have therefore attempted to combine the advantages of both canal wall-down and canal wall-up techniques. The posterior wall is kept up, the mastoid is obliterated with adipose tissue, the attic is exteriorized in the ear canal and hearing is restored with a minimal-size hypotympanic cavity only. Preliminary results from 41 cases with a follow-up of 6 months to 6 years suggest that skin conditions in the enlarged ear canal are adequate and that cholesteatoma do not recur.
