Results of myringoplasty and type I tympanoplasty with the use of fascia, cartilage and perichondrium grafts

Since the publication of Miodoński, Zollner and Wullstein different methods and grafting materials have been promoted in tympanoplasty. The purpose of this study was to demonstrate the anatomical and functional results of tympanoplasty in comparison with the material used. The studies included a selected group of 142 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. The comparison group consisted of 30 patients when fascia of the musculus temporalis was used to close a defect of the eardrum. 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. The comparison of operation results showed that there was no significant difference between the two groups.
