The aim of this study is to analyse the long-term anatomical and functional outcomes and prognostic factors of the canal wall down (CWD) tympanoplasty for the treatment of tympano-mastoid cholesteatoma. A total of 895 patients treated for tympano-mastoid cholesteatoma with follow-up longer than 10 years were included. Recidivism (recurrent and residual) cholesteatoma rates and functional results were analysed. The rate of recidivism was 7.7% (6.7% persistence and 1% recurrent disease). Recidivism was higher in paediatric patients (10.1% versus 5.0% of adults). Pathological middle ear mucosa and pars tensa was associated with increased rates of recidivism. Postoperatively, air pure-tone-average (aPTA) <= 30 dB was achieved in 36.4% of patients. Of 895 patients, a revision CWD tympanoplasty for chronic otorrhoea was performed in 14 cases (1.5%) with complete recovery in all cases. Nine of those patients had a recurrence of cholesteatoma and five had cavity problems related to granulation, de-epithelisation or recurrent infection. Paediatric patients and absence of stapes superstructure were associated with the worst auditory outcomes. Six-month results were always better than long-term results. A CWD approach was demonstrated to be effective, achieving the goals of cholesteatoma treatment.
