Readily available tragal cartilage has been found to be a very beneficial autogenous graft source for construction of prostheses to correct those defects in the ossicular chain that frequently occur when the incudostapedial joint is destroyed by middle ear pathology, particularly by the retraction of the posterior, superior quadrant of the tympanic membrane against and/or around the incudostapedial connection. This is true whether there be only erosion of the incus just at the joint, or whether there is erosion of the entire long process of the incus together with the superstructure of the stapes. The various types of deformity and the particular tragal cartilage prosthesis tailored for each deformity, and designed for maximum gain in hearing, are presented together with representative pre‐ and postoperative audiograms for the variety of types.
