  • Title: Maxillary expansion and protraction in correction of midface retrusion in a complete unilateral cleft lip and palate patient.
    Author: Kawakami M, Yagi T, Takada K.
    Journal: Angle Orthod; 2002 Aug; 72(4):355-61. PubMed ID: 12169036.
    Abstract:
    A 7-year-old girl with a cleft lip and palate had a midface retrusion due to growth inhibition of the maxillary complex. She presented for correction of a severe total crossbite with a Class III skeletal pattern. Initially, maxillary expansion was provided to widen the maxilla and then maxillary protraction headgear was worn to improve the sagittal skeletal relation. Fixed orthodontic appliances were placed to align the dentition and Class III elastics were used to establish intercuspation and stability. The maxillary expansion and protraction usually provide effective improvement in skeletal Class III patients with repaired cleft lip and palate patients. The success of the orthopedic procedure essentially depends on the individual growth of the maxilla and the mandible. This case report shows the significant growth of the mandible after maxillary expansion and protraction in late adolescence.
