Thyroplasty

surgical technique(s) to improve the human voice by altering single or multiple structures of the larynx, which houses the vocal folds (vocal cords) with the related controlling nerves, muscles, and cartilage. Typically, this surgery is considered to improve the position or tension of the vocal folds which can improve vocal volume and production. This is also known as laryngeal framework surgery. The most common technique may be to insert small blocks of custom-shaped silastin just inside of the tracheal wall, pushing the vocal fold muscle inward (medialization). This typically strengthens the output of a weaker voice but it also reduces the exchange volume of pulmonary function, as the tracheal opening has been permanently reduced. This surgery is named for its proximity to the thyroid gland.
