ABSTRACT
Position of the tongue was studied in lateral cineradiographic pictures of 15 patients with cleft palate and velopharyngeal incompetence, and from ten unaffected reference subjects. The patients were examined before and after pharyngoplasty. Before operation there was no difference in the degree of tongue/velum contact between the patients and the reference subjects, but after the operation, contact was lost in 13 of the 15 patients because the tongue was lowered and the velum raised by the pharyngeal flap. This contradicts the previous theory that the position of the tongue should be expected to be higher to maintain the posterior oral seal. The tongue was in a more posterior position in the patients than in the reference subjects both before and after operation. After operation the tip of the tongue retracted into the anterior oral cavity. The posterior and downward change in position of the tongue may account for part of the posterior and downward growth pattern of the lower third of the face which occurs in children after pharyngoplasty. A loss of tongue-lip balance around the premaxilla may be one of the factors that causes the maxillary retrusion that has been reported after pharyngoplasty in patients with cleft palates.
