Modern voice surgery has evolved into a highly specialized field that blends medical precision with acoustic artistry. Today’s surgical innovations allow for safe, minimally invasive procedures that restore, refine, or transform the human voice — whether to treat medical conditions or to align voice with gender identity and personal goals.

At Yoskarn Clinic in Bangkok, Thailand, Dr. Somyot Kunjak and his team bring over 40 years of ENT and phonosurgery experience, offering patients world-class care supported by advanced technology and proven surgical innovation.


1. Cricothyroid Approximation (CTA)

Cricothyroid Approximation is one of the most common procedures used in voice feminization surgery. By approximating (bringing closer together) the cricoid and thyroid cartilages, the vocal folds are stretched and tightened, resulting in a higher pitch and softer resonance.
This method offers predictable, stable results and can be combined with other fine-tuning techniques for optimal vocal outcomes.


2. Anterior Commissure Advancement (ACA)

Anterior Commissure Advancement shortens the effective length of the vibrating vocal folds by moving their anterior attachment point forward.
This procedure further elevates vocal pitch and produces a smoother, more natural feminine tone, often used alongside CTA for enhanced precision.


3. Type III Thyroplasty (Relaxation Thyroplasty)

For patients seeking a deeper or more masculine voice, Type III Thyroplasty is the gold standard.
This technique involves relaxing the vocal folds by reshaping the thyroid cartilage, thereby lowering pitch and producing a richer, resonant sound without affecting vocal clarity.


4. Laser & Endoscopic Voice Surgery

Laser and endoscopic microsurgery represent a leap forward in minimally invasive voice care.
These advanced tools allow surgeons to remove nodules, cysts, or lesions with exceptional precision and minimal tissue trauma.
They are also used for fine adjustments in both feminization and deepening procedures, ensuring optimal healing and natural vocal performance.


5. Injection & Augmentation Techniques

For aging or atrophic vocal folds (Presbyphonia), Yoskarn Clinic offers vocal fold injection laryngoplasty, using biocompatible materials to restore volume, closure, and tone.
This technique is quick, safe, and effective — often performed under local anesthesia with minimal downtime.
