Voice Feminization Surgery / VFS

Voice Feminization Surgery (VFS) in Bangkok, Thailand

Voice affirmation surgery (VAS) is a procedure designed to achieve a more feminine speaking voice. Sometimes referred to as gender-affirming voice care, the procedure is complex and should only be performed by surgeons with specialized training and equipment. A speech pathologist will assist patients in adapting their voices to achieve communication patterns consistent with gender identity.

Styles of speech, voice tones, accents, and language style are highly personal and vary greatly. Voice training alone can take years of frustrating and expensive lessons, and success is often elusive. Through voice affirmation surgery, pitch, resonance, and volume can be altered to provide a more gender-appropriate speaking voice. Post-surgery, one week of silence is required before the introduction and lessons from trained coaches or speech pathologists.  

1. Open Feminization Laryngoplasty, Cricothyroid Approximation (CTA), Thyroplasty type IV.

Surgical technique

              The goal of this operation is to surgically move the thyroid cartilage closer to the cricoid with non-absorbable stitches. The vocal cords are not directly touched but passively stretched. This procedure increases vocal pitch by stimulating the contraction of the cricothyroid muscle with the suture. This increases the distance between the vocal fold attachments and raises the tension of the vocal fold. The cricoid and thyroid cartilage are moved as close as possible because postoperative reversion to a slightly lower pitch is inevitable to some extent as swelling resolves and tissues relax. The fundamental frequency of the voice rises to overlap the biological female range perceptively. The operation is performed under general anesthesia. The duration of the surgery is about 40-50 minutes, and the surgical reduction of Adam’s apple can be performed simultaneously. Generally, the patient doesn’t feel any postoperative pain; however, pain may occur if Adam’s apple surgery is done. This pain is mild and easily controllable with painkillers.

              A transverse incision scar is made in an existing skin crease and, if possible, at the level of the vertical midpoint of the thyroid cartilage on the throat, a minor surgical opening, around 2 cm, leaving an almost invisible scar. 


  • This procedure does not interfere with or create scars on the vocal cords, potentially leading to permanent hoarseness.

  • Theoretically reversible if the patient is dissatisfied.

  • The surgical reduction of Adam’s apple can be performed simultaneously.


  • Requires a neck incision.

  • Long-term results have yet to be discovered as it's a newer procedure. 

2. Open Laryngoplasty with anterior vocal fold shaving technique

              This surgical technique, open laryngoplasty, is performed under general anesthesia. The procedure involves making a small incision (approximately 2-4 cm) in the midline of the neck, just above the thyroid cartilage. The surgeon then opens the cartilage at the midline and removes the central segment.

              The anterior part of the true and false vocal folds are then removed and pulled together. This procedure is typically done to reduce the size of the vocal folds and improve the patient's voice.

              In this procedure, you can reduce the size of your Adam's apple through the same incision. Some patients might experience a vibrating quality to their voice after surgery for a few weeks, but it usually improves back to normal eventually.

  • Comfortable speaking pitch

  • Alters the physical size of the larynx to a close approximation of the female larynx

  • The high tone of the frequency


  • The roughness of the voice in some patients

  • Risks of infection and airway compromise in the immediate postoperative

  • The procedure is longer and more complicated.

  • Long time for recovery

Pre-operation for Voice Feminization Surgery

              Before undergoing voice feminization surgery, you may be asked to follow specific instructions to prepare for the procedure. These instructions may vary depending on the particular needs of the individual and the recommendations of their surgeon, but they may include:

  • Quit smoking and avoid tobacco use for a certain period before and after the surgery, as smoking can interfere with healing and increase the risk of complications.
  • Avoid medications that can interfere with bleeding or healing, such as aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs), unless instructed otherwise by your surgeon.
  • Avoid consuming alcohol for a certain period before and after the surgery.
  • Fast for a certain period before the surgery, as directed by your surgeon.
  • Inform your surgeon about any medications you take, including prescription, over-the-counter, and herbal supplements.
  • Arrange for transportation to and from the surgery, as you may be unable to drive after the procedure.
  • Follow any other specific instructions your surgeon provides, such as showering with an antimicrobial soap before the surgery.

Follow these instructions carefully to ensure the best possible outcome from the surgery. Discuss the instructions with your surgeon if you have any questions or concerns.

Post-operative Care for Voice Feminization Surgery

  • Day 1 to 7: You must remain silent until the first follow-up. There are no food and drink restrictions.
  • Day 3 to 7: Keep the vocal cords lubricated by drinking lots of water and nebulizing with a sterilized saline solution. 
  • Day 8 to 10: After the vocal rest period, a new videolarygostroboscopic and spectrum-acoustic study is performed. The outer stitches are removed, the dressing is changed, and speech therapy rehabilitation can start.

The speech therapist will teach the patient how to use her new voice as effectively as possible. The final result will be seen between the third and eighth month after surgery. For this reason, a follow-up is recommended in the third, sixth, and twelfth months after surgery.


              The surgical team reserves the right to assess the feasibility case by case if the upcoming patient has already undergone the voice change surgery using a different technique and is not satisfied with the result of their voice.

              To prevent acid reflux, it’s highly recommended to avoid caffeine, chocolate, peppermint, fatty foods, acidic foods, soda, and alcoholic drinks.

              One week off from work is sufficient as long as you can follow the voice restrictions. Two weeks off are required if you need to use your voice.

Risk and Complications for Voice Feminization Surgery

              As with any surgical procedure, voice feminization surgery carries certain risks and potential complications. These may include:

  • Bleeding
  • Infection
  • Scarring
  • Changes in voice quality or pitch that are not satisfactory to the patient
  • Damage to the vocal cords or surrounding tissues
  • Difficulty speaking or swallowing
  • Anesthesia risks

Are the results from VFS Permanent?

Voice feminization surgery is a surgical procedure designed to alter the voice of individuals who identify as transgender or non-binary to better align with their gender identity. The goal of the surgery is to create a voice that is perceived as feminine, with a higher pitch, lighter tone, and improved articulation.

“The question of whether the results from voice feminization surgery are permanent is a common one among those considering the procedure.”

In general, the results from voice feminization surgery are considered to be permanent, meaning that the changes to the voice are long-lasting and do not revert back over time. However, the success and permanency of the results can vary depending on various factors, such as:

The individual's anatomy

The surgeon's skill and experience

The patient's vocal hygiene and post-operative care.

It's important to note that:

While the surgical procedure itself can bring about significant and lasting changes to the voice, the process of feminizing the voice is not limited to surgery alone. Voice therapy and speech coaching can also play an important role in achieving a desired feminine voice. In some cases, speech therapy is recommended after the surgery to help the individual learn to use their new voice effectively and to develop good vocal habits.

The process of voice feminization is not a one-time event and can take time, patience, and dedication. Some individuals may experience setbacks or may need multiple surgeries to achieve their desired voice.

“With proper care and attention to vocal hygiene, the results from voice feminization surgery are often long-lasting and can bring significant improvements to an individual's quality of life and confidence.”

In conclusion,

While the results from voice feminization surgery are generally considered to be permanent, the success and permanency of the results can vary depending on a number of factors. The process of feminizing the voice is a journey that requires patience, dedication, and a combination of surgical and non-surgical approaches.
