| Abstract: | The dependence of the postoperative hearing function on the shape of the reconstructed tympanic cavity has been evaluated. After reconstructing a large tympanic cavity, the results were very good; after reconstructing a flat tympanic cavity they were good and after reconstructing a cavum minor they were bad. The main cause of bad long-term hearing ability after type IV tympanoplasty was tympanofibrosis. The global results were better following closed tympanoplasty than following open tympanoplasty. |
