Abstract
The goal of myringoplasty is to reconstruct the tympanic membrane and the sound conducting mechanism ,
Cartilage has proved to be a promising graft material for closing perforations in the tympanic membrane.
Cartilage is the preferred graft material for tympanic membrane reconstruction in our otological practice, we use tragal cartilage for both tympanic membrane and ossicular reconstruction.
The rigidity of the cartilage prevents resorption, re-perforation and retraction, even in the context of continuous eustachian tube dysfunction.
However, this rigidity can counteract sound conduction properties. so, the cartilage should be cut as thinly as possible.
The average thickness of the tragal cartilage reported is 1 mm.
In order to prevent thick cartilage interfering with sound conduction, we prefer to slice the tragal cartilage, different techniques to split the thickness of tragal cartilage have been reported, in our technique of cartilage-perichondrium composite graft myringoplasty, we split the tragal cartilage with a precise mathematical Kurz® Precise Cartilage Splitter to attain cartilage of a definite thickness.
