Abstract：Objective To investigate treatment of stageⅢexternal auditory canal cholesteatoma (EACC) with damage to the posterior external auditory canal and mastoid. Methods Eight patients with stageⅢEACC underwent intact canal wall mastoidectomy with tympanoplasty and canal wall reconstruction with autologous cortical bone. Results On follow-up, all pa-tients showed physiological external auditory canal structures and improvement of listening ability without stenosis or lesion re-currence, except for one patient who needed a revision operation for a fistula between the reconstructed wall and the mastoid. Conclusion Intact canal wall mastoidectomy with tympanoplasty and canal wall reconstruction with autologous cortical bone is an effective treatment technique worth further in-depth study.
