[Velopharyngeal sequels in labial-alveolar-velopalatine clefts. Orticochea dynamic pharyngoplasty]

Sphincter pharyngoplasty is one of the treatments for velopharyngeal insufficiency, in cleft palate patients. After Hynes, Orticochea described a procedure which became the reference. After studying 2 series of patients treated by two different surgical procedures, it appeared that the speech improvement was nearly the same. Improvement of the results was obtained when the surgical procedure took into account the physiopathology of the velopharyngeal insufficiency. When the velar mobility was weak or absent, but with an effective mobility of lateral pharyngeal walls, a pharyngoplasty with a pharyngeal flap and a superior pedicle was chosen. On the opposite, with an effective velar mobility, sphincter pharyngoplasty was chosen. When both were poor (velar and lateral pharyngeal walls), it seems that using a pharyngeal flap with a velum pushback gave the best result. If hypernasality persisted after pharyngoplasty, a second procedure had to be performed.
