Facial appearance and speech outcome may affect psychosocial functioning in girls and boys. Several studies reported dissatisfaction with facial appearance and more specifically the lip and mouth profile in children with cleft lip and palate (CLP). An appropriate lip and tongue function is essentialfor facial aesthetics (e.g., lip competence, interdental tongue behavior), speech production and non-verbal functions like chewing, swallowing and facial emotional readability. Few authors assessed oral strength in children with cleft lip and palate. Therefore, the purpose of this controlled study wasto measure the tongue and lip strength and endurance in boys and girls with CLP.References• Clark, H, & Solomon, N (2012) Age and sex differences in orofacial strength, Dysphagia, 27(1), 2–9.• Lembrechts D, Verschueren D, Heulens H, Valkenburg HA, Feenstra L.

However, these distortions were not related to a decreased lip or tongue strength as measured withthe IOPI. In conclusion, the results of this controlled study demonstrated normal lip and tongue functions in young subjects with unilateral CLP as measured with the IOPI. The surgical correction of the pathological lip anatomy leads to a normal lip function in these subjects with a unilateral CLP.The ENT specialists and speech pathologists must be aware of this aspect.ResultsDiscussion and conclusion
