Head and Neck Surgeons Pioneer Gender-Affirming Transoral Endoscopic Chondrolaryngoplasty for Transgender Patients

Surgeons at NewYork-Presbyterian/Weill Cornell Medicine recently published a case report demonstrating the feasibility and outcomes of chondrolaryngoplasty performed through the lower lip vestibule using an endoscopic approach. They are the first academic clinicians in the country to report the outcomes of scarless neck feminization. The report was published in the May 2023 issue of the journal The Laryngoscope.

Chondrolaryngoplasty is a surgical approach to minimizing the appearance of the Adams apple by reshaping or shaving down the laryngeal prominence. For years, this procedure has been performed using an open surgical approach, resulting in an external scar in the front of the neck that is not only a cosmetic issue but may "out" transgender individuals by revealing they had the operation. The NewYork-Presbyterian/Weill Cornell Medicine team is pioneering this new surgical technique to provide gender-affirming care.

"One of the problems with performing neck surgery is that it is a very visible area of the body. Scars in the neck are not easy to conceal. This becomes not only a cosmetic issue but a health care privacy issue. May patients would rather keep these operations private and avoiding a visible incision is a clever way to do this,” explains NewYork-Presbyterian/Weill Cornell Medicine otolaryngologist Victoria Banuchi, MD. "With the endoscopic approach, patients are very grateful after the operation. They feel whole and don't have any visible stigma showing what they went through."

A typically male characteristic of the neck, the laryngeal prominence forms early during puberty. Testosterone has a lengthening effect on the laryngeal cartilage. It is permanent and once it has formed, it cannot be reversed with hormone replacement therapy. "Some of our patients report the laryngeal prominence as playing a major role in their gender dysphoria. Once the prominence is formed it cannot be reshaped by estrogen therapy alone and surgery is therefore the most effective way of reshaping it,” Dr. Banuchi notes. She has been performing endoscopic thyroid surgery for years and refined the technique to spare patients from a visible neck scar. Dr. Banuchi then began to wonder if the surgical technique could be used in other patients having neck surgery. She met Israeli head and neck surgeon Avi Khafif, MD, who had been using the transoral approach for chondrolaryngoplasty in transgender patients. "I knew the approach offered the perfect exposure to this procedure given that the laryngeal prominence if a landmark we almost always encounter during endoscopic thyroid surgery," she says. She started to perform the technique herself with some refinements. Dr. Banuchi worked with NewYork-Presbyterian/Weill Cornell Medicine otolaryngologist Samuel Helman, MD, to develop a technique to safely perform scarless chondrolaryngoplasty.

One of the possible complications of chondrolaryngoplasty is damage to the anterior commissure, where the vocal cords attach into the laryngeal cartilage. If the cords become destabilized, the voice deepens — a side effect that is a problem for transgender women who often engaged in voice therapy for voice feminization. With the approach designed by Drs. Banuchi and Helman, the surgeon places a soft suture at the site of the anterior commissure to act as a guidepost. “The suture tells me where the anterior commissure is so I can take out the cartilage above it. I can’t go beyond it because it will affect the patient’s voice,” explains Dr. Banuchi. The suture is removed at the end of the procedure.
