Functional Outcomes of Single-Stage Ossiculoplasty in Chronic Otitis Media With or Without Cholesteatoma*

Two-stage ossiculoplasty has been widely used for hearing improvement in chronic otitis media with or without cholesteatoma. However, the outcomes of single-stage ossiculoplasty have not been fully clarified.The aim of this study is to determine whether the outcomes of single-stage ossiculoplasty are comparable with those of 2-stage ossiculoplasty in chronic otitis media with or without cholesteatoma.Medical records of 191 cases (187 patients) who underwent single-stage ossiculoplasty from January 2011 to May 2018 at our hospital were retrospectively reviewed.Polycel and titanium were used in 56 and 135 cases, respectively. In chronic otitis media without cholesteatoma, the success rate of polycel and titanium partial ossicular replacement prosthesis was 80.7% and 81.6%, respectively. In chronic otitis media with cholesteatoma, the success rate of polycel and titanium partial ossicular replacement prosthesis was 63.6% and 64.6%, respectively, while that of polycel and titanium total ossicular replacement prosthesis was 45.9% and 47.8%, respectively.These results suggest that single-stage ossiculoplasty is a suitable option for recovering postoperative hearing in chronic otitis media with or without cholesteatoma. Thus, if middle ear inflammation can be sufficiently treated in the first stage, single-stage ossiculoplasty is a suitable option for chronic otitis media with or without cholesteatoma.
