Vibration of tympanic membranes of the middle ear model with TORP and flat membrane made of gum were studied by means of holographic interferometry. Results were as follows. 1) As the tension of the gum became high, the amplitude decreased in low frequency. The segmental vibration was observed in low frequency as the tension became low. 2) The difference between 0.03mm and 0.06mm was not signif...

Objective. The aim of this study is to evaluate the results of inlay butterfly tympanoplasty technique in large central tympanic membrane perforations. Methods. The files of the patients who underwent inlay butterfly cartilage tympanoplasty for large central tympanic membrane perforations were reviewed. Patients were followed with otoscopy and audiometry. Preoperative and postoperative pure-ton...
