We have performed canal wall down tympanoplasty with mastoid obliteration as a fundamental surgical treatment for patients with acquired cholesteatoma for complete removal of the lesion and prevention of cholesteatoma recurrence. To avoid postoperative gap formation on the posterior canal wall, canal wall reconstruction using bone pate plate was performed after removal of both the anterior and posterior buttresses. Then the mastoid cavity was thoroughly obliterated with cortical bone slices to prevent the recurrent cholesteatoma. No recurrent lesion has been found on long-term observation after these procedures. Canal wall down tympanoplasty with mastoid obliteration is a useful technique for preventing recurrent cholesteatoma and postoperative mastoid cavity problems.
