Are long-term auditory results following ossiculoplasty with bone cement as successful as early-middle period results?

Abstract

Bone-cement (BC) ossiculoplasty is one of the options to solve ossicular chain problems. Many authors reported successful results in the early or mid-follow-up period; however, there is no long-term result in the literature. We aim to evaluate long term results of BC ossiculoplasty. Forty-eight patients who underwent BC ossiculoplasty as incudostapedial re-bridging by the same surgeon were invited to evaluation. Postoperative otomicroscopic examination was performed. Pre-operative and post-operative audiological results after longer follow up and graft success rate were noted. Fourteen patients came for control examination. The follow-up period was between 87 and 135months (mean 102months). None of the patients had graft failure. Ten patients had early postoperative follow-up results (between 10 and 52; mean 24months). In the comparison of preoperative and early postoperative air-bone gap, there were significant differences in all frequencies while the comparison of preoperative and long-term postoperative results showed a significant difference only in 250 and 500Hz. Early postoperative results were better than late with significant difference only in the 2000 and 4000Hz. As reported by many studies, bone cement application provides a significant auditory improvement in the early postoperative period. The results of the present study showed that this early auditory success may decrease over time with a long-term follow-up. Further studies should be conducted with larger patient groups to clarify the long-term benefits of this treatment and possible causes for its deterioration.
