The human voice is a powerful reflection of identity, confidence, and communication. When voice changes occur due to aging, hoarseness, or gender transition, modern surgical techniques can safely and effectively restore or modify vocal tone and strength.

At Yoskarn Clinic in Bangkok, under the leadership of Dr. Somyot Kunjak and his expert team with over 40 years of experience in ENT and voice surgery, patients receive world-class diagnosis, precision surgical treatment, and personalized rehabilitation for every type of voice condition.


Overview of Voice Surgery

Voice surgery (phonosurgery) involves medical or surgical techniques designed to improve, restore, or modify vocal function. These procedures are performed on the vocal folds or surrounding structures to correct hoarseness, weakness, pitch imbalance, or aesthetic voice concerns.
Yoskarn Clinic provides a full range of voice surgeries for both medical and aesthetic purposes, supported by stroboscopic imaging, microsurgical tools, and minimally invasive laser systems.


Voice Surgery for Hoarseness

Chronic hoarseness caused by nodules, polyps, or scarring can be treated with microlaryngoscopy or endoscopic microsurgery, which precisely removes lesions while preserving natural vocal quality.
Combined with postoperative voice therapy, patients regain clarity and endurance safely and effectively.


Voice Surgery for Aging Voice

Aging-related vocal weakness, known as Presbyphonia, results from thinning and reduced closure of the vocal folds.
Yoskarn Clinic offers vocal fold augmentation using injection laryngoplasty or implants to restore volume, improve strength, and bring back a youthful, resonant tone.


Voice Feminization Surgery

For transgender women and cisgender individuals seeking a softer, higher-pitched voice, voice feminization surgery reshapes or tightens the vocal folds to elevate pitch and modify resonance.
Dr. Somyot Kunjak performs advanced procedures such as Cricothyroid Approximation (CTA) and Anterior Commissure Advancement (ACA) to achieve natural, stable, and feminine vocal characteristics — complemented by tailored voice therapy for lasting results.


Voice Deepening Surgery

In contrast, voice deepening surgery helps transgender men or individuals with naturally high voices achieve a richer, lower tone.
Through careful adjustment of the vocal fold length and tension, Yoskarn Clinic delivers results that are both natural and durable, matching the patient’s desired gender expression and communication style.


Surgical Techniques & Innovations

Cricothyroid Approximation (CTA)

CTA increases vocal pitch by bringing the thyroid and cricoid cartilages closer, effectively tightening the vocal folds. It is often used in feminization surgeries and provides permanent pitch elevation.

Anterior Commissure Advancement (ACA)

ACA shortens the effective vibrating length of the vocal folds, raising pitch while preserving clarity and control — a preferred method for patients seeking subtle, stable results.

Laser & Endoscopic Methods

Modern CO₂ laser and endoscopic microsurgery allow for precise, minimally invasive correction of vocal fold lesions, scars, and tissue irregularities, reducing recovery time and scarring.
