Abstract

|
Patients with cleft lip and palate present severe maxillary hypoplasia due to scar of lip and palate, often accompanied by compromised mastication, speech abnormalities. Sometimes maxillary hypoplasia persist even though active orthodontic treatment was done. In theses cases, patients born with cleft lip and palate will be potential candidates for maxillary advancement with bone grafting after growth to correct the functional deformities and improve aesthetic facial proportions. But, maxillary advancement using standarf surgical approaches has several limitations: increased relapse tendency after maxillary advancement, necessity of additional bone graft and mandibular setback surgery.
Distraction osteogenesis is current treatment modality to overcome these limitations, thus has become popular for treatment of maxillary hypoplasia associated cleft lip and palate, craniosyntosis. Especoally, rigid external distraction, contrary to internal device, has adbantages; better vector control of osteotomized segment, effective traction of the bony segments, the ease of the application and removal the distraction device.
This study showed that relatively successful result could be generated by using rigid external distraction osteogenesis(RED) in the case of cleft lip and palate with severe maxillary hypoplasia, 6 years 7 months old.
