A Novel Method of Hybrid Ossiculoplasty: Ionomer Bone Cement Coated Mastoid Cortical Bone

Abstract

Objective: The development of otologic surgical techniques has significantly improved the functional results of surgery. However, the issue of the most effective ossiculoplasty material is still controversial. The study aimed to introduce a novel method of autologous ossiculoplasty, using “ionomer bone cement coated mastoid cortical bone” and to assess short-term and long-term results of this method.

Material and Methods: The study presented a retrospective, consecutive case series of twelve patients who underwent revision surgery as type IV tympanoplasty using Mastoid cortical bone coated with ionomer bone cement in our institution between January 2013 and December 2019. Coating with ionomer bone cement was performed to prevent the autograft from sticking to the surrounding bone tissue. The short- and long-term auditory functions and otologic examination findings of the patients were analyzed.

Results: Physical examination findings were satisfactory. Except one, all patients had a significant improvement in hearing outcomes, and the late-term results were also satisfactory. An average long term audiological gain of 19.9 dB (± 8.7 SD) was found.

Conclusion: A novel method of Hybrid Ossiculoplasty: Ionomer Bone Cement Coated Mastoid Cortical Bone is an effective and safe method of ossiculoplasty. It can be easily eliminated one of the major disadvantages of mastoid cortical bone by coating it with ionomer bone cement.
