    Abstract:
    Bone cement is a good and cheap option for some ossicular chain problems such as incudostapedial re-bridging. The purpose of this retrospective study is to evaluate the audiologic results after reconstruction of three different types of ossicular chain defects, using bone cement. Group 1 consists of 42 patients who underwent an ossiculoplasty using bone cement between the damaged long process of the incus and an intact stapes superstructure. Group 2 consists of 46 patients in which incus interposition between malleus and stapes superstructure was performed, using bone cement to fix the interposed incus. For group 3, consisting of 32 patients who had a present malleus, a defective long process of the incus and a missing stapes superstructure, a re-shaped incus was placed between the stapes footplate and the malleus and bone cement was again used as a fixator. Preoperative and postoperative pure-tone audiometric findings were obtained and hearing differences were assessed. The mean preoperative and postoperative air-bone gaps were 34.8 and 15.6, 35 and 18.4, and 43.4 and 19.8 for groups 1, 2, and 3, respectively. There was a significant improvement in hearing outcomes in all the groups when comparing preoperative and postoperative mean air-bone gaps (p < 0.001). The postoperative air-bone gap was ≤20 dB in 76 % of patients in group 1, 64 % of patients in group 2, and 46 % of patients in group 3. Bone cement is an effective and cheap option for some ossicular chain problems such as incudostapedial re-bridging. It may also be used to fix the interposed incus to the stapes superstructure and/or malleus to avert displacement.
