Between 1963 and 1992, 145 footplates were inadvertently mobilized during otosclerosis surgery. After a vein graft, a 4.0-mm Robinson prosthesis was placed on all footplates, making no attempt to remove the footplate. There were 73 thin, blue footplates and 72 thick, white footplates. Hearing results in the thin, blue footplate group was 97% successful and 100% satisfactory at 3 years. No footplate refixed. In the thick, white group, hearing was 60% successful and 72% satisfactory at 6 months. Footplate refixation was found at revision in all but one unsuccessful case. After revision, the thick, white group had 79% successful and 89% satisfactory hearing results at 3 years. No patient in either group was worse. We conclude that placing a vein graft and a Robinson prosthesis is a safe and effective technique for a mobilized footplate. If the footplate is thin and blue, there is little or no risk of refixation. If the footplate is thick and white, approximately 30% will require revision. | lld:pubmed |
