Medium-term hearing outcomes after 116 ossiculoplasties using hydroxyapatite (HA) and cartilage were reviewed in this paper. The successful rate of hearing outcomes was 83.0% in the HA group and 63.8% in the cartilage group (p<0.05). A multivariate analysis showed that HA was a significantly better prognostic factor than cartilage (odds ratio 2.77). Concerning postoperative complication, extrusion of HA was found in one case in the HA group. On the other hand, there was no complication in the cartilage group.
