Abstract     Unilateral cleft lip and alveolus (UCLA) is an inherited disorder where the lip and alveolus are affected to different degrees: from a minimal to a complete cleft, which affects the whole upper lip, alveolus and the hard palate anterior to the incisive canal. Every form of orofacial clefts represents a more or less extensive communication between the oral and nasal cavities, and demands functional adaptation and compensation. We postulated that the cleft represents -a functionally important disturbance of the act of amniotic fluid swallowing and of developement of the sucking reflex. According to our hypothesis the foetus compensates the disturbance by sealing the cleft with its tongue. Altered morphology reflects this compensation and is characteristic for the individual form of the cleft. The purpose of our research was to establish the morphological characteristics of the upper part of the oral cavity in newborns and 6-month infants with UCLA; to evaluate the influence of cleft size on the dimensions of the upper part of the oral cavity and to establish individual changes in infants with CLA from birth until the age of 6 months. Sixty three plaster casts of the upper part of the oral cavity taken from 20 newborns and 43 6month infants were grouped according to the degree of the cleft, and were analysed using a trigonometric method. Thirteen out of 50 infants with UCLA had plaster casts taken at birth and before the surgical procedure. We used plaster casts of 25 healthy infants of corresponding age for controls. The morphological characteristics of the upper part of the oral cavity are different between newborns and 6-month infants with UCLA, compared with healthy infants of coresponding age. Comparison with non-cleft infants indicates that infants with UCLA have greater sagittal and transverse dimensions of the upper part of the oral cavity. (Abstract truncated at 2000 characters)
