    Abstract:
    OBJECTIVE: The prostheses known as biocompatible are usually proposed for columellar repair in absence of stapes but at which cost and which long-term tolerance? It appeared useful to study the possibilities of autograft ossicular reconstruction (incus and cortical bone) in absence of suprastructure of the stapes. MATERIAL AND METHODS: Retrospective study for 82 operated patients for cholesteatoma with lysis of the cruras of the stapes. Columellar repair was obtained by prosthesis, columella of cortical mastoid bone, and more often autograft of incus (54 cases). The technique of Autogreffe Tympanum-Cartilage-Os-Platinum (ATCOP) (Autograft Tympanum-Cartilage-Bone-Footplate is described: tympanic repair by fascia and cartilage from the concha is made at the first surgical step. Type III ossiculoplasty is performed at the second look. The distance tympanum-footplate is then lower than 6 mm and the body of the incus, preserved as a spare ossicle in the mastoid, has a sufficient length to be interposed in between new drum and footplate. RESULTS: 78% of the patients have final air bone gap less or equal than 30 decibels. The average post op air bone gap is 23 decibels with incus while it was 42 decibels before surgery. Average gain is 19 decibels. The cost of autograft is null and tolerance is excellent. CONCLUSION: Patient's incus is usable in type III ossiculoplasty thanks to a cartilage graft of the tympanic membrane. Patient's ossicle is a material of choice for columellar repair even in absence of the suprastructure of the stapes. Prostheses in biomaterial appear justified in case of absent or destroyed incus.
