Palatopharyngoplasty and Palatal Anatomy and Phenotypes for Treatment of Sleep Apnea in the Twenty-first Century: Successful palatopharyngoplasty is critical for successful sleep apnea surgery. Traditional uvulopalatopharyngoplasty was primarily excisional, whereas newer techniques, such as expansion sphincterpharyngoplasty, are more reconstructive. Studies of flow dynamics even demonstrate that the effectiveness of maxillofacial surgery is significantly mediated through stiffening and enlargement of the lateral retropalatal and pharyngeal airway. The current modified technique of uvulopalatopharyngoplasty/expansion sphincteroplasty aims to maximize relocation and tension on the palatopharyngeus muscle, opening the retropalatal airway and the palatal genu, and minimizing tension on the final mucosal closure.
