Incudostapedial Rebridging Ossiculoplasty with Bone Cement

OBJECTIVE: This study reports the authors' technique and hearing results with bone cement reconstruction of the incudostapedial chain. The technique is called incudostapedial rebridging ossiculoplasty. STUDY DESIGN: A retrospective analysis of the hearing results of the incudostapedial rebridging ossiculoplasty was performed on 15 patients. BACKGROUND: Recently, bone cements have been available commercially, and their use in otologic surgery is increasing. Polymaleinate glass ionomer cement is a commercially available bone cement that can be used to reconstruct a discontinuity between the incus and the stapes. SETTING: Tertiary referral center. PATIENTS: Disease-free or cleansed middle ear and mastoid and intact ossicular chain except for discontinuity between the long process of the incus and the head of the stapes. INTERVENTIONS: Therapeutic. MAIN OUTCOMES MEASURES: Functional results of incudostapedial rebridging ossiculoplasty. RESULTS: Of 15 patients, 9 achieved a successful hearing result (an air-bone gap within 20 dB) with incudostapedial rebridging ossiculoplasty after 1 year. The mean preoperative and postoperative air-bone gaps were 32.9 and 14.3 dB, respectively. CONCLUSIONS: Incudostapedial rebridging ossiculoplasty with bone cement is a cost-effective and safe procedure that yields good hearing results in selected patients.
