title: [Videofluorographic study of swallowing in patients with severe motor and intellectual disabilities--II. Impairment of oral phase].
abstract: We studied swallowing movements in 14 patients with severe motor and intellectual disabilities and development of the impaired oral phase. The oral phase in the patients did not develop beyond the late weaning phase. They had impairment of the oral phase: poor or absent lip seal, infantile swallowing, slowed or stalled bolus transit, and oral residue after swallowing. Videofluorographic studies revealed severe impairment in the transitional and pharyngeal phases: pooling of liquid barium in the hypopharynx prior to swallowing, the delay of cricopharyngeal relaxation, aspirated liquids (silent aspiration 77.8%), aspirated purees, pooling of purees in the pharynx after swallowing. After videofluorographic studies we made some efforts to provide patients with better management; changes in food textures and posture during drinking and eating. These efforts eased their feeding difficulties. Videofluorographic studies could be helpful in evaluating swallowing disturbance in the oral phase and thereby preventing chronic aspiration, malnutrition and feeding difficulties in patients with severe motor and intellectual disabilities.
