Objective To evaluate the postoperative results and usefulness of bone cement application in repairing ossicular chain defects, to discuss surgical technique, and to compare preoperative and postoperative ABG. Study design This was a prospective case series study. Patients and methods This study was carried out in the ORL-HNS Department, Zagazig University Hospital and Hearing and Speech Institute, from March 2014 to March 2017, on 20 patients with ossicular chain defect. Rebridging of ossicular discontinuity was done by glass monomer bone cement in all patients. Results In this study, successful hearing restoration could be achieved in 95% of the patients represented, as 55% of the patients had hearing improvement (dB gain) of more than or equal 10 dB, and 20% of patients had hearing improvement (dB gain) more than 20 dB, and 20% of patients had hearing improvement (dB gain) of more than 40 dB, after 12 months. Conclusion Incudostapedial joint rebridging ossiculoplasty with ionomeric bone cement is a reliable method for ossicular reconstruction that is cost effective and offers satisfactory hearing results in selected patients.
