[Posterior canal wall reconstruction--the results of a prolonged-follow-up (author's transl)].
The preservation or reconstitution of a normal external auditory canal with the obliteration of or maintenance of an aerated maistoid cavity is possible by reconstruction of the lateral attic wall and posterior canal wall. Conserved homograft cartilage and autograft cartilage or bone are considered suitable. Connective tissue and lyophilised dura are not suitable. Rejection of implants and recurrence of cholesteatoma will worsen the eventful successful outcome such that the initial success of over 90% is reduced to 75%. A longer follow-up admittedly is necessary for satisfactory assessment.
