How to treat UVFP?
Medialization thyroplasty Type I (MT) is the gold standard treatment for glottis insufficiency, by inserting alloplastic or autologous materials into the paraglottic space to achieve glottis closure. In patients with a large glottis gap or high vagal lesions, arytenoid adduction (AA) can be performed to reduce the posterior glottis gap and correct the vertical height difference between the vocal folds.
Currently, several products are available in the market, including silastic implants, Gore-Tex stripes, or titanium plates.
