Vocal Cord Injection (Injection Laryngoplasty)
Our voice is one of the most frequently used tools for communication in daily life. However, due to aging or various health issues, hoarseness, weak voice projection, or vibration disorders may occur. Especially in cases of unilateral vocal cord paralysis, the vocal cords cannot close fully, resulting in a weak and hoarse voice. Vocal cord injection (injection laryngoplasty) is a fast and effective treatment method used to address such voice loss.
During this procedure, biocompatible fillers are injected into the vocal cords to add volume. This improves glottic closure, enhances vibration quality, and results in a stronger, clearer voice. It is particularly effective for individuals who experience voice loss due to aging, neurological disorders, postoperative complications, or congenital structural issues.
Advantages of Vocal Cord Injection
- Quick and easy to perform. It does not require surgical intervention.
- Can be performed under local or general anesthesia.
- Provides immediate improvement and voice strengthening.
- Patients can return to daily life in a short time.
Vocal cord injection is especially beneficial for individuals who use their voice professionally.
Is Vocal Cord Injection Permanent? Does It Need Repeating?
The durability of vocal cord injections depends on the type of filler used and the patient’s vocal habits. The effect usually lasts between 6 months and 2 years.
Longevity of Fillers by Type:
- Temporary fillers (hyaluronic acid, collagen, etc.): Effective for 6 months to 1 year. These are absorbed by the body and may need to be repeated periodically.
- Medium-term fillers (polycaprolactone, calcium hydroxyapatite, etc.): Typically last for 1 to 2 years.
- Permanent fillers (silicone, polytetrafluoroethylene, etc.): Rarely used and may require surgical intervention.
In individuals who use their voice intensively, such as vocal professionals, the injected material may dissolve faster and require repeat procedures. For a more permanent solution, medialization thyroplasty or phonomicrosurgery may also be considered.
