Uvulopalatopharyngoplasty (UPPP) has been the most commonly performed procedure for obstructive sleep apnea. However, high failure rates of this procedure, which can reach 50%-70% of the cases, have led to various modifications in the UPPP technique to address persistent obstruction after traditional UPPP surgery. Expansion sphincteroplasty was developed as a modification of UPPP to address lateral wall collapse proximal to the free margin of the palate and transpalatal advancement pharyngoplasty was developed as a modification of UPPP to address more proximal anterior posterior narrowing of the retropalatal segment. Transpalatal advancement has also been shown to address proximal lateral wall airway narrowing.
