["Crown-cork tympanoplasty"--a method for complete reconstruction of the tympanic membrane]

Abstract

The crowncorktympanoplasty is a technique for the total reconstruction of the tympanic membrane, recommended in cases of ear malformation, blunting-phenomena and total deficiency of the membrane caused by chronic otitis media. Autologous tragal composite graft is used for the myringoplasty. While the cartilage faces to the middle ear cavity, the overflapping perichondrium is layed on the bony meatal wall in the manner of a crowncork. 10 cases performed in the last two years are reported. In each one an intact tympanic membrane could be reached. In average, the ear bone gap could be reduced for 18.5, 17.5, 16.5 and 13.5 dB in the frequencies of 500, 1000, 2000 and 4000 Hz.
