At Yoskarn Clinic in Bangkok, Thailand, surgical innovations in voice restoration and pitch modification are grounded in over four decades of clinical experience and research. Led by Dr. Somyot Kunjak, a pioneer in phonosurgery and laryngology, the clinic continues to refine surgical methods for both functional and aesthetic voice enhancement.
These studies and clinical trials form the scientific foundation for every voice operation performed at the clinic, ensuring outcomes that are both safe and anatomically sound.
Over the years, Yoskarn Clinic has contributed to the refinement of several major surgical methods used worldwide in voice and pitch modification. Key approaches include:
Cricothyroid Approximation (CTA): Used for voice feminization (MTF), this method increases vocal fold tension by approximating the thyroid and cricoid cartilages, resulting in a higher pitch and brighter tone.
Type III Thyroplasty: Designed for voice masculinization (FTM), this surgery relaxes the vocal folds to lower pitch and produce a deeper, more resonant voice.
Anterior Commissure Advancement (ACA): Enhances pitch elevation by modifying the anterior vocal fold attachment.
Laser and Endoscopic Phonosurgery: Enables precise tissue removal, scar revision, or correction of subtle vibratory abnormalities with minimal trauma.
Each method has been refined through years of clinical trials, stroboscopic evaluations, and long-term follow-up data, ensuring superior outcomes across different patient populations.
The surgical technique studies at Yoskarn Clinic combine evidence-based research with real-world patient outcomes. This includes:
Anatomical and histological studies on the vocal fold structure and surgical response
Comparative analysis of outcomes between different techniques (CTA, ACA, and thyroplasty)
Voice acoustic studies measuring pitch, resonance, and clarity before and after surgery
Postoperative voice therapy protocols integrated into recovery to enhance long-term stability
The findings from these studies contribute to international conferences and peer-reviewed journals, helping shape global standards for voice modification and rehabilitation.
Dr. Somyot Kunjak’s team applies microsurgical precision, advanced endoscopic imaging, and intraoperative monitoring to minimize tissue trauma and preserve natural vibration. Ongoing innovations include hybrid approaches that blend traditional surgery with laser-assisted fine-tuning, resulting in faster recovery and improved voice quality.
Every technique is continually evaluated through clinical outcome tracking and acoustic laboratory data, ensuring measurable progress in both safety and performance.
