[The evaluation of cartilage and perichondrium grafts for the reconstruction of the tympanic membrane].

Since the publication of Miodoński, Zollner and Wullstein different methods and grafting materials have been promoted in tympanoplastic surgery. The purpose of this study was to demonstrate the anatomical and functional results of tympanoplastic surgery with the use of cartilage and perichondrium grafts. The studies included a selected group of 112 patients who were operated on because of perforation of tympanic membrane. The analysed group consisted of 112 patients when perichondrium and cartilage were used to reconstruct the tympanic membrane. In all cases before and after operation there was made tonal audiometry with indication for air and bone conduction within range from 500 to 4000 Hz, verbal audiometry after operation with indication of speech detection and speech reception threshold using mono-syllable NLA-93 test, tympanometry after operation and evaluation of anatomical results after surgery.
