OBJECTIVES: To evaluate the range of multiple swallowing in normal subjects by ultrasonography. METHODS: Twenty-two normal subjects swallowed 5 or 10 ml of tap water or a semisolid meal. RESULTS: With water multiple swallows were seen in 41% of the subjects examined and was related to the volume of the bolus:18% of the cases were 5 ml and 36% were 10 ml. Sixty-eight percent of subjects had multiple swallows with semisolid boluses. CONCLUSION: These results differ from those reported with videofluoroscopy of modified barium swallowing. Ultrasonography should be used in future studies of normal and pathological oral swallowing.
