BACKGROUND: Autologous cartilage has been widely used as a material for tympanoplasty and mastoid-obliteration surgery. Since it remains vulnerable to an @entity166 , this study aims to evaluate if it can be used for a chronic suppurative cholesteatomatous ear to achieve single-stage tympanoplasty with mastoidectomy and obliteration of the cavity. METHODS: From January 1988 to August 1998, the records of @entity1 with @entity3540 who received cartilage-obliteration surgery performed by Dr. Lien were examined for any @entity281 within three months after the operation. The Fisher's exact test was used to compare the difference in the incidence of post-operative @entity281 between suppurative ears and non-suppurative ears. RESULTS: One hundred and seven surgical procedures performed upon 96 @entity1 were included in this study, with 97 being primary surgical procedures and ten being revision surgery for previous open cavity with @entity3540 recurrences. The average follow-up was 47.7 months. At time of surgery, there were 59 non-suppurative ears; 48 ears were suppurative and cultured. Granulations were found in the middle ear or mastoid for 42 ears (39.3%). Five ears (4.7%) exhibited infection-associated post-operative problems within three post-operative months. Three cases (5.1%) were non-suppurative ears and two cases (4.2%) were suppurative ears. There was no significant statistical difference when examined with the Fisher's Exact test. CONCLUSIONS: In an immunocompetent @entity1 with a @entity2169 , autologous cartilage could potentially tolerate an infection condition to serve as a material for mastoid-obliteration in a single-stage surgical procedure.
