Abstract

Background Ossiculoplasty is a commonly performed middle ear procedure. Ossicular chain reconstruction (OCR) prostheses should be made of a biocompatible material; one such common material is hydroxyapatite (HA). Methods 2 patients were identified who had HA OCR prostheses which had fused to the middle ear bony structures. One HA OCR had fused to the fallopian canal in the tympanic segment and represented a management dilemma. The other fused to the scutum. Conclusion Bony ankylosis of a HA containing OCR prosthesis should be considered in the differential diagnosis of a failed ossiculoplasty. Depending on the location of the fusion, special measures may be needed to free the prosthesis from the underlying middle ear structures.
