Summary Cheek pressure during swallowing was measured on six operated complete cleft lip and palate cases (4–8 years of age) before and after expansion of buccal segments of maxillary arch, As control, seven non‐cleft subjects with acceptable occlusion of the same age level were used. Before expansion, the pressures in the cleft cases were much higher than the controls. Immediately after expansion, increase in pressure was observed in cases which received rapid expansion. However, a few months after expansion, most cases showed a decrease in pressure. This is explained as being due to the adaptation of the perioral musculature to the expanded dental arch and/or the disappearance of hyperactivity of the perioral musculature during swallowing.
