抄録

Long-term results of ossiculoplasty using autografts (malleus, incus, cortical bone and cartilage) and 2 types of ceramic ossicular prostheses, Bioceram® and Apaceram®, were analyzed in 298 tympanoplasties. Analysis focused on the recurrence of inflammation, the migration and extrusion of materials used for ossiculoplasty and hearing acuity.<br>Recurrence of inflammation and postoperative hearing acuity were not related to the materials used for ossiculoplasty. Prosthetic extrusion was observed in 6.7% of Bioceram® and 11.8% of Apaceram® prostheses, and migration was found in 26.0% of Bioceram® and 5.9% of Apaceram® prostheses, while only 3.3% of ears using autografts demonstrated extrusion or migration of columellae. However, extrusion or migration was not observed in the ears without inflammation, such as cases of middle ear anomalies.<br>These results suggest that ossiculoplasty using autograf is is more recommendable than ossiculoplasty using ceramic ossicular prostheses in cases of inflammatory middle ear disease such as chronic otitis media and cholesteatoma.
