Retropharyngeal abscess as a result of hyaluronic acid injection pharyngoplasty: A first of its kind

Velopharyngeal insufficiency (VPI) results when the soft palate fails to occlude the communication between the nasopharynx and the oropharynx during speech, resulting in hypernasal speech resonance. VPI may result from shortening of the soft palate or functional limitations of the soft palate, or the posterior or lateral pharyngeal wall musculature. Surgical procedures have traditionally been aimed at lengthening the soft palate, dynamically tightening the velopharynx, or statically reducing the size of the velopharynx with autologous tissue transfer.
