Voice Feminization: CTAThe Cricothyroid Approximation surgery raises

vocal pitch by stimulating cricothyroid muscle contraction through the approximation of the cricoid and thyroid.

The surgery is performed in an inpatient setting under general anesthesia.

CTA ProcedureThe neck is prepared

and draped in a sterile manner.

I made a 1.5-2 cm transverse incision is made in an existing skin crease over the cricothyroid.

CTA ProcedureThe front of the voice box is

removed thus making the voice box smaller. (This removes the projection of the Adam's apple at the same time.

The vocal cords are then stretched and the front third to half of the cords are removed to shorten them.

CTA Procedure

A thyrohyoid elevation may also be performed at the same time to try raising the voice box in the neck. This attempts to shorten the pharynx to feminize a portion of the resonance chamber (pharynx).

A thyrohyoid elevation consists of passing sutures around the hyoid bone to hold the voice box in an elevated position in the neck.
