  • Look Inside

A method of stabilization of a columella in tympanoplasty was developed. An edge of carti-lage columella was thinned and inserted between the tympanic membrane and manubrium. The other end was placed on the capitulum or foot-plate. Chorda tympani nerve was rest on the columella. The columella was stabilized between the tympanic membrane and manubrium.

This method was performed in 20 cases of tympanoplasty; type III with a columella in 16 cases and type IV with a columella in 4. Average postoperative air-bone gap was 7. 2 dB in type III and 11. 3 dB in type IV. All cases showed hearing improvement of less than 20 dB air-bone gap.
