Stem Cell is becoming one of the most well-recognized miracle medicine of this generation with its application in almost anything from its original role in regenerative medicine to its now emerging us in cosmetics and aesthetic medicine and at Yoskarn Clinic in Thailand, the use of Stem Cells has already found its way to Voice Rejuvenation.
Voice Rejuvenation is the surgical procedure to correct Vocal Fold Paralysis, the condition that most commonly causes hoarseness and aspiration due to glottal insufficiency. Other techniques such as filler injection and/or fat transfer along with Open-neck Medialization Thyroplasty are already available treatments for the condition, however filler and fat transfer may not be permanent options as fillers can be reabsorbed in 6-12 months while fat transfer also has a high chance of reabsorption. Medialization Thyroplasty, on the other hand, is quite an invasive procedure with a certain time of recovery, and is therefore not a very popular option.
The role of the 3 available techniques is to bring the paralyzed vocal fold medially to produce stronger sounds. Physiologically, we have 2 true vocal folds that vibrate and close to produce sound. When one of these vocal folds stop closing, air can pass through without much vibration, making the quality of the voice that was produced, weak, and airy. The available procedures all aim to push the paralyzed vocal fold medially, the Stem Cell Injection will also aim for that result but as stem cells has the unique capacity to differentiate into another form of cell, making their result more permanent that fat transfer and fillers, and the procedure, a lot less invasive than Open-neck Medialization Thyroplasty.
While Stem Cell treatment is still not a recognized treatment for any disease or condition, several research are being conducted to prove or disprove its uses and benefits.
Stem Cell Injection however, with its minimal-invasive approach, will require very little downtime of 2-3 days. Patients who had undergone the procedure are recommended to allow the area to heal by speaking only if necessary for the first few days following surgery. Patients can however proceed with day to day activities without abruption from this procedure.
