sphincter pharyngoplasty
Pronunciation: SFINK-ter fair-in-go-plas-tee
Surgical creation of a dynamic muscular ring in the pharynx to improve velopharyngeal closure.
Full Definition
Sphincter pharyngoplasty is a surgical procedure that creates a dynamic muscular ring in the upper pharynx to treat velopharyngeal insufficiency. The procedure involves transposing portions of the palatopharyngeus muscles from the lateral pharyngeal walls to create a sphincter-like mechanism that can contract during speech. Unlike pharyngeal flaps, which create a static obstruction, sphincter pharyngoplasty allows for dynamic closure that can adapt to different speech requirements. The procedure is particularly indicated for patients with poor lateral pharyngeal wall movement. Success rates are comparable to pharyngeal flaps with potentially fewer complications related to airway obstruction.
Usage
Usage note: Named after Dr. Orticochea who popularized the technique.
