Transcutaneous injection laryngoplasty is a treatment option that aims to improve glottal incompetence by moving one or both of a patient's vocal folds toward the midline, reducing the loss of air and thereby improving the symptoms. 92% of patients showed statistically significant benefit after 3 months post injection. Vocal fold injection is considered a safe, reliable, and highly effective method of treatment. This procedure can be done in an operating room or during an office visit, depending on the type of material used and your preference. The results from the injection can last anywhere from two to three months to years, again depending on the type of material used.
