Thyroplasty
Thyroplasty
Thyroplasty (pronounced: thy-ro-plas-tee) is a surgical procedure performed on the thyroid cartilage in the larynx, often to improve the voice quality of individuals with certain voice disorders.
Etymology
The term "thyroplasty" is derived from the Greek words "thyreos" meaning shield (referring to the shield-like shape of the thyroid cartilage) and "plastos" meaning formed or molded.
Procedure
Thyroplasty involves the insertion of an implant into the larynx to alter the position or length of the vocal cords, thereby changing the pitch, loudness, or quality of the voice. The procedure is often performed under local anesthesia and can be categorized into four types: Type I, II, III, and IV, each addressing different voice issues.
