The use of cortical bone grafts in ossiculoplasty. III: Audit of costs.

This paper describes the results of a comparative audit of the costs of using artificial prostheses and cortical bone. The costs of using a bone graft have been calculated by estimating the expenses incurred as a result of the additional time required for preparation of the grafts. The mean cost of preparing a graft was 29.10 pounds, while the mean cost of using a prosthesis was 65.01 pounds.
