  • Title: Tympanoplasty: cartilage prostheses--a report of 564 cases.
    Author: Altenau MM, Sheehy JL.
    Journal: Laryngoscope; 1978 Jun; 88(6):895-904. PubMed ID: 651506.
    Abstract:
    We reviewed 564 tympanoplasties operated upon over an eight year period at the Otologic Medical Group in which tragal cartilage was used to re-establish the sound pressure transfer mechanism. Eighty-six percent of the cases were revisions, and half of these were planned second stage procedures. In the majority of cases the stapes crural arch was missing. The conductive deficit in these cases was reduced to 20 db or less in 67% and 10 db or less in 40%. The commonest single cause of failure was a short prosthesis. There were no instances of cartilage resorption. Extrusion occurred in one case. Tragal cartilage has been more satisfactory than ossicular tissue in many situations. Recently we have been using plastic prosthesis (TORP and PORP) in combination with tragal cartilage and believe that the results will be even better.
