There is not one single operative approach to surgical correction of VPI. The surgical approach typically depends on the size of the velopharyngeal opening, its location, and the cause. With diagnostic tools the surgeon is able to decide which technique should be used based on the anatomical situation of the individual. The goal of every operation is to achieve the best possible result with the technique assigned to each individual case, without causing upper airway obstruction and sleep apnea.Nowadays the procedure that is chosen the most from the palatoplasties is the pharyngeal flap or sphincter palatoplasty.
