Injection Pharyngoplasty With a Hyaluronic Acid and Dextranomer Copolymer to Treat Velopharyngeal Insufficiency in Adults

Injection pharyngoplasty with a readily available Dx/HA is an effective treatment for VPI that allows for titration to complete velopharyngeal closure under local anesthesia or light sedation. It is most effective in patients with nonmalignant etiologies of VPI and in those with good lateral wall motion. Complications experienced were postoperative neck pain and occult retropharyngeal fluid collection, highlighting the importance of follow-up.
