Abstract

The effect of levator muscle sling formation in cleft palate surgery was evaluated by electrical stimulation of the muscle at surgery. Palatal movement before and after sling formation was recorded using a force transducer. After muscle sling formation the soft palate had been elevated more effectively toward the retropharynx and its mobility increased remarkably. The surgical procedure, which had been proposed on the basis of anatomical considerations, proved to be effective for improving velopharyngeal function.
