Like the rest of the body, the voice changes with the passage of time. And in recent decades, injectable drugs have again been used mostly to treat frown lines, crow’s feet and laugh lines. But as the relevance of cosmetic surgery to medicine has increased, ENT specialists have discovered in clinical practice that injecting this drug into thinning vocal cords can help restore the treated person to having a youthful voice. It turns out that as people age, the deterioration in the quality of the sound emitted by the vocal cords is all related to a weakening of the breath or a reduction in the frequency range of the voice. At the same time, there are many different treatments available for the aging voice. However, although there are many ways to treat the vocal cords, among the tests of vocal cord treatments including voice exercises or surgical voice changes, otolaryngologists have found that collagen injections have the best effect on improving the vocal cords, and thus collagen injections have become a widely used treatment for vocal cord recovery. Tips: For people with hoarseness or other voice problems, it is a good idea for the ENT surgeon to use a small camera to look at the larynx and do some tests to identify the disease before deciding whether collagen injections can be used. However, it is important to note that the post-operative effects of collagen injections are not permanent and therefore need to be re-injected every 2 to 4 months to maintain the effect.
