Surgical treatment of velopharyngeal insufficiency

Velopharyngeal insufficiency (VPI) is a common complication after primary palatoplasty. Although the several surgical treatments of VPI have been introduced, there is no consensus guide to select the optimal surgical treatment for VPI patients. The selection of surgical treatment for VPI depends on a multimodal patient evaluation, such as perceptual speech evaluation, nasometery and nasoendoscopy. We can provide more adequate treatment for VPI through the deeper understanding of anatomy and physiology in VPI.
