Voice Deepening surgery aka Fat Injection Thyroplasty: This surgery is performed by injecting fat into the patients vocal cords, adding bulk and creating a deeper-sounding voice. Theres a saying that goes: ?sounding good is as important as looking good." Cost: $2000 to $5000, sometimes as low as $1,000. (injections can last up to 2yrs)
- Medialization laryngoplasty: In this procedure, the folds of the vocal cords are thickened with silicone rubber implants, which causes a deeper tone to develop. This is a common surgery among FtM individuals, I'm not sure they will perform it on a healthy/normal males but it's worth looking into.
Cost: $2500
- Thyroplasty: one to two and half inch incision is placed parallel to, or in a skin crease of your neck near the Adams apple. A diamond-shaped cut centered on the vocal cords loosens the vocal cords internally. An endoscope is in place during the procedure to observe your vocal cords, after this you are typically asked to make some sounds to assess the loosening. The incision is closed.
Cost: $1,000 to $2,500
- Micro-laryngeal Pitch reduction: A laser is used to incise some of the laryngeal tissue on the top surface of the true vocal cords and the bulk is transferred to near the vibrating edge of the vocal cords, increasing their mass. The vocal cords may also be loosened with some cuts. These changes in tension and mass can lower the comfortable speaking pitch.
