Abstract

The incidence of monozygotic twins with cleft lip and palate is very low, and there have been few studies of longitudinal observations. The observation of monozygotic twins with different types of cleft lip and palate from the perspective of jaw growth facilitates comparison and evaluation of the effects of extrinsic and intrinsic factors. In this study, we observed monozygotic twin sisters with bilateral cleft lip and palate (BCLP) and unilateral cleft lip and alveolus (UCLA). In the child with BCLP in whom collapse occurred during jaw development, we placed a palatal plate and maxillary expansion appliance in infancy, and longitudinally compared her with her sister with UCLA. Although there were no marked differences in the growth or development of the middle face between the sister with BCLP, in whom jaw guidance was performed from birth, and the sister with UCLA at the age of 7 years and 11 months, mandibular growth in the inferior direction was noted in the sister with BCLP.<br>The results suggest that careful follow-up of both patients, including occlusal control, is necessary.
