cricothyroid approximation
Pronunciation: cry-ko-THY-roid ap-PROX-ih-may-shun
Surgical voice restoration procedure tightening vocal fold tension by approximating the cricoid and thyroid cartilages.
Full Definition
Cricothyroid approximation is a voice surgery technique that increases vocal fold tension and fundamental frequency by surgically bringing the cricoid and thyroid cartilages closer together. This procedure mimics the natural action of the cricothyroid muscle and is commonly performed as part of voice feminization surgery or to address certain types of vocal fold paralysis. The surgery results in elevated pitch and increased vocal fold stiffness, requiring post-operative voice therapy to optimize voice use and prevent compensatory behaviors.
