Preoperative anthropometric analysis of the cleft child's face: a comparison between groups.

This study examines the facial surfaces of different groups of cleft babies aged up to eleven months, prior to any corrective surgery, with the aim of identifying and assessing differences in their facial morphology. Measurements of standard anthropometric landmarks were made on plaster casts taken pre-operatively of the faces of babies presenting for surgical correction of lip and palate deformities. Periorbital and mid face measurements show no difference between control and cleft groups. The nasal base is shown to be wider in infants with cleft lip on both cleft and non-cleft sides. Upper lip measurements indicate shortening, lateral deviation and superolateral rotation. A diagrammatic model is proposed to illustrate facial anatomy in control and cleft individuals. Modifications to the technique are proposed. Further study in this field is suggested, in order to produce a comprehensive database of facial morphological changes in the cleft and non-cleft populations both pre-operatively and over time, with a view to producing a potential redefinition of the cleft syndrome based on anthropometric principles.
