Previous studies1 indicate that cleft palate consists not of an underdevelopment of tissue but of an abnormal displacement of the fully developed parts of the palate. It was also demonstrated that there is no tendency for the deformity to increase after birth. Measurements of the faces of children with clefts of the lip were so taken as to indicate the position of various parts of the nose in regard to the tragus of the ear and the position of the margins of the clefts in regard to the tragus. An analysis of these measurements is here reported.
This investigation was made to determine how much displacement of tissues had occurred in these children and also to find if such displacement is modified with age on account of unequal growth or continued unopposed muscle pull.
The measurements were made on the same children whose palates were previously measured,1 i.
