Voice Masculinization Surgery / VMS

Female to Male Voice Surgery or Voice Masculinization Surgery / VMS in Bangkok, Thailand

This type of surgery is performed if the patient is not satisfied with his voice despite the use of male hormone therapy. Unlike the female voice, a lower fundamental frequency of the voice is associated with men.

Before the surgery, an accurate Video Laryngostroboscopy and spectrum-acoustic study of the voice will be performed to highlight the natural and fundamental frequency and to plan the best operation to achieve the patient's goals.

A masculine voice is low-frequency, around 100-125 Hz, which is lower than the average frequency for men's voices.

The surgical technique involves a 2-3 cm incision in the neck area. The external laryngeal structure is identified, and the diameters are reduced. The vocal folds are shortened to make the voice deeper and lower pitch.

This technique is very safe and doesn’t interfere with your vocal fold.

After the operation, you can feel mild dysphagia, phlegm in your throat, and lumpness.

You should be admitted to the hospital for 1-2 nights for this procedure.

Post-operative Care for Voice Masculinization 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 nebulize with a sterilized saline solution. 
- Day 8 to 10: A new videolarygostroboscopic and spectrum-acoustic study is performed after the vocal rest period. The outer stitches are removed, the dressing is changed, and the 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 at the third, sixth, and twelfth months after surgery.

Note: 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 your voice is needed.

Tricks to get a clear voice

 Here are a few tips to help improve the clarity of your voice:

  1. Hydrate: Drinking plenty of water can help keep your vocal cords lubricated, making life-changing it more accessible to speak clearly.
  2. Warm-up: Just like athletes warm up before a big event, it's a good idea to warm up your voice before speaking for a long time. This can include exercises such as humming, lip trills, and tongue twisters.
  3. Use good posture: Maintaining good posture can help you breathe more efficiently and improve the clarity of your voice. Stand up straight, keep your shoulders back, and keep your head held high.
  4. Use good breathing technique: Diaphragmatic breathing can help to support your voice and improve its clarity. This involves breathing deeply into your diaphragm instead of shallowly into your chest.
  5. Speak at a moderate pace: Speaking too quickly can make it difficult for others to understand you, while speaking too slowly can make you sound monotonous. Try to find a pace that feels natural and comfortable for you.
  6. Use appropriate volume: Speak loud enough to be heard but not so loud that your voice strains.
  7. Avoid speaking when you are congested or have a sore throat: If your vocal cords are inflamed, it can be challenging to speak clearly.
  8. Avoid smoking, excessive alcohol, and caffeine. All of these can dry out your vocal cords and make speaking more difficult.
  9. Practise good vocal hygiene, including singing like a warm-up, avoiding overusing your voice, and taking breaks to rest it.

Remember, speaking is a skill that can be developed and improved over time with practice and attention to technique.
