What is Thyroplasty?
Thyroplasty involves a collection of surgical procedures to treat voice disorders by changing the cartilages of the larynx that surrounds the vocal cords. Thyroplasty helps in restoring the voice after paralysis or altering the pitch of the voice. It is also known as laryngeal framework surgery.
What are the types of Thyroplasty?
- Type I Thyroplasty
During this procedure, the vocal cords are placed near each other to reduce the results of the abductor spasms.
- Type II Thyroplasty
During this procedure, the vocal cords are spread apart by a shim, which separates the vocal cords and does not bring them in contact during the spasms.
How is Thyroplasty performed?
- Local anesthesia along with intravenous sedation is applied on the patient.
- An incision is made on the neck crease.
- The soft tissues and muscles are put apart to reach the framework of cartilage of the larynx.
- Topical anesthesia is applied in the nose and fiberoptic laryngoscopy is performed to view the vocal cords.
- The patient may be asked to speak during the procedure to test the voice improvement while adjustments are being made on the vocal cords.
- Steroids are usually used to reduce swelling, as swelling can make it difficult to make accurate estimates about the size of the implant and placements. Swelling may also damage the airway.
- The incision is then closed and covered with a dressing.
