ABSTRACT
This article presents a technique of surgical debridement of temporal bone cholesteatoma in congenital atresia of the external auditory canal and a description of a clinical case. In the presence of congenital atresia of the external auditory canal with cholesteatoma, surgical treatment with posterior transcortical access is most often performed with the formation of a large trephined cavity, followed by myringoplasty and, if necessary, ossiculoplasty. We have described a clinical case of surgical treatment of congenital atresia of the external auditory canal by the type of separate atticoanthromastoidotomy with myringoplasty and formation of the external auditory canal with simultaneous rehabilitation of temporal bone cholesteatoma. This method allows performing cholesteatoma surgery in congenital atresia of the external auditory canal with the formation of the canal of the external auditory canal, while maintaining the spatial ratio of all its walls. This reduces the risk of developing restenosis of the external auditory canal and improves the patient’s hearing.
