Velopharyngeal Insufficiency After Le Fort I Osteotomy in a Patient With Undiagnosed Occult Submucous Cleft Palate.

The authors present a 16-year-old patient with no known history of cleft palate who developed velopharyngeal insufficiency after a Le Fort I osteotomy performed for the correction of maxillary hypoplasia and a Class III malocclusion. Postoperative evaluation revealed the presence of velopharyngeal insufficiency and subtle findings of an occult submucous cleft palate. She had a pharyngeal flap 6 months later with successful correction of the velopharyngeal insufficiency. This case illustrates the need to screen for submucous cleft palate prior to orthognathic surgery. (C) 2017 by Mutaz B. Habal, MD.
