Pharyngoplasty in patients with cleft lip and palate after maxillary advancement.
The development of velopharyngeal incompetence and increased hypernasality after maxillary advancement has been described previously by several authors. If speech and velopharyngeal function deteriorate after maxillary advancement, pharyngoplasty is frequently the treatment procedure of choice because of the natural cause of the deficit. Of 91 cleft lip and palate patients who have undergone maxillary advancement at the Australian Cranio-Facial Unit, 23 patients received a pharyngoplasty after surgery. Thirteen of these patients who had pre- and postoperative speech evaluations were included in this study. Of the 13 patients, six patients received a superiorly based pharyngeal flap, two patients underwent an orticocheal pharyngoplasty, and five patients received either a revision or augmentation of the previous flap based on results of preoperative examinations. Serial nasendoscopic evaluations were available for 11 of these 13 patients, and they demonstrated that velopharyngeal function improved after pharyngoplasty in six patients and was unchanged in five patients. Of the 13 patients, 10 improved and three patients were unchanged on an intelligibility rating. Nine of the 13 patients demonstrated decreased hypernasality and four patients were unchanged. Hyponasality decreased in two patients increased in one patient, and was unchanged in one patient. Because the results obtained are considered acceptable, the authors conclude that pharyngoplasty can be used effectively to treat velopharyngeal dysfunction subsequent to Le Fort I maxillary advancement.
