Abstract

Patients with unilateral cleft lip and palate (UCLP) usually present unilateral cross bite due to collapse of the maxillary minor segment. Unequal expansion of the palate is needed to resolve this problem in UCLP patient. Unilateral segmental palatal distraction (USPD) after Le Fort I osteotomy and the oblique placed orthodontic expansion screw (Hyrax) can be used to correct the unilateral cross bite. 1his case report describes the effects of USPD of the collapsed maxillary minor segment on patient with unilateral cleft lip and palate.
