Surgical treatment of adult cholesteatoma : long-term follow-up using total reconstruction procedure without staging

• Conclusions:A total of 330 cases of adult cholesteatoma were operated with canal-wall down (CWD) and total reconstruction procedure (TRP) without staging. Independent of preoperative middle ear conditions, cholesteatoma extent and localization, long-term improvement of hearing with a low incidence of residual and recurrent disease were achieved.Objectives:To evaluate long-term surgical and hearing results using a well-defined surgical technique without staging in adult cholesteatoma.Methods:The same CWD surgical technique, including obliteration of the mastoid cavity, reconstruction of the canal wall, and ossiculoplasty with autologous bone, was used by three senior surgeons (1982-2004). Preoperative and postoperative pure tone average (PTA) for air conduction (AC), bone conduction (BC), and air-bone gap (ABG) were assessed and compared 1, 3, and 6 years after surgery. Various prognostic factors with potential influence on long-term hearing outcome were evaluated.Results:Recurrence of AC occurred in 10%, residual disease in 3%. Six years after surgery all patients except one had a dry ear and over 92% of all cases were water resistant. Three patients developed complete deafness. Long-lasting improvement and/or preservation of hearing, with maintenance of PTA-ABG closure in 68% of all cases within 20 dB, were obtained. Sixty-four (19%) ossicular revisions were performed.
