Home » Voice Surgery » Cricothyroid Approximation (CTA)
Cricothyroid Approximation (CTA) is a specialized surgical procedure primarily used in voice feminization surgery to raise the pitch of the voice and create a softer, more feminine tone. This technique is widely recognized for its precision and reliability, helping transgender women and individuals seeking pitch elevation achieve a natural and stable vocal outcome.
At Yoskarn Clinic in Bangkok, Thailand, Dr. Somyot Kunjak and his team, with over 40 years of ENT and phonosurgery experience, are experts in performing CTA with meticulous care, ensuring safe, effective, and long-lasting results.
CTA works by shortening and tightening the vocal folds. The procedure involves approximating (bringing closer together) the cricoid and thyroid cartilages, which stretches the vocal folds and increases vocal tension. This change raises the pitch of the voice while maintaining natural resonance and clarity.
Unlike non-surgical methods or hormone therapy, CTA provides a permanent anatomical adjustment, making it a preferred choice for those seeking long-term feminization of the voice.
Transgender women seeking a higher, more feminine voice
Individuals with naturally low or flat pitch who desire a softer tone
Patients who want a permanent solution beyond voice therapy
CTA is often combined with Anterior Commissure Advancement (ACA) or post-operative voice therapy to refine resonance and speaking patterns for optimal results.
Preoperative Evaluation
Yoskarn Clinic performs a thorough assessment using stroboscopy, acoustic analysis, and vocal measurements to plan a customized surgical approach.
Surgical Technique
Performed under general anesthesia, the cricoid and thyroid cartilages are carefully approximated using microsurgical techniques. Precision is key to ensuring correct vocal fold tension and pitch elevation.
Postoperative Care
Voice rest is recommended for several days, followed by specialized voice therapy to optimize vocal control, resonance, and natural tone. Most patients notice immediate pitch improvement, with results stabilizing over a few weeks.
