Summary :
Objective: To analyze the results obtained with hydroxy-apatite bone cement (HABC). Patients: A total of 73 ossiculoplasties with HABC were evaluated. Ears were divided into 4 groups: Group 1: Reinforcement of the incudo-stapedial joint with HABC; Group 2: Reconstruction of an incus long process defect with HABC; Group 3: Partial ossicular reconstruction between stapes and malleus handle with HABC; Group 4: Reconstruction of stapes with mobile or fixed footplate with moderate or extensive incus long process erosion using a titanium piston glued to the incus remnant using HABC. Results: The mean follow-up was 21 months. The percentage of postoperative average air-bone gap (ABG) ≤ 20 dB for groups 1, 2, 3 and 4 were 100%, 95%, 83% and 91% respectively; for ABG ≤ 10 dB: 90%, 71%, 50% and 50%. No complications related to HABC and extrusion occurred. Conclusion: Today, the use of HABC seems to help us improve our functional results and also to avoid extrusion. In our experience, ossiculoplastie with HABC seems to provide better and more stable functional results. HABC is safe and easy to use. The use of cement with or without biocompatible ossicular prostheses allows us to repair different types of ossicular defects whilst trying to conserve an anatomical and physiological ossicular chain. Reconstruction of the incus long process or incudo-stapedial joint defect with cement is preferable rather than using partial ossicular reconstruction with HABC.
