OSSICULOPLASTY USING THE BLACK HYDROXYLAPATITE HYBRID OSSICULAR REPLACEMENT PROSTHESES

The problems of ossicular reconstruction in chronic ear surgery have l ed to the development of new ossicular replacement prostheses. Improve ments in biocompatibility and design led to the development of hydroxy lapatite hybrid (HaH) ossicular replacement prostheses. The senior aut hor's (M.E.G.) experience with the Black HaH prostheses is reviewed. S ixty cases are grouped by procedure and prosthesis (19 TORPs and 41 PO RPs) with a minimum follow-up of 1 year. Audiometric data are analyzed to determine the success rate in air-bone gap closure. Complication a nd extrusion rates are reviewed. These results are compared against th ose obtained using other prostheses using similar criteria, and this r eport serves as a follow-up on a previous paper on this subject by the senior author.
