Abstract
Gore-Tex migration from a window in medialization thyroplasty was prevented by using an outer perichondrial flap of the thyroid ala. A relatively large flap of the outer perichondrium was elevated before a window usually opened. After a strip of Gore-Tex was inserted to fold down, the perichondrial flap was then sutured to close the window and to fix the Gore-Tex. This method was performed in sex senile patients, and a satisfactory result was obtained. Although Gore-Tex is easily fixed in young patients using a Nylon string and a connected needle, an ossified thyroid ala makes needle penetration difficult in elderly patients. Therefore, fixation of the Gore-Tex with a perichondrial flap is useful, especially in medialization thyroplasty for senile patients.
