Description

This case report describes postoperative skeletal stability in a unilateral cleft lip and palate (UCLP) patient who received maxillary distraction osteogenesis (DOG) using a rigid extraoral distractor (RED) for maxillary advancement.<br>The patient was a Japanese female with right UCLP who had presented at our orthodontic clinic at 5 years and 10 months of age. She received autologous secondary bone grafting (SBG) using cancellous bone from the iliac crest at 7 years and 6 months of age. Since the phase-1 orthodontic treatment to facilitate maxillary growth using a face mask did not work effectively, the objective of the phase-2 treatment was to correct midface hypoplasia.<br>The maxilla was advanced by DOG using RED with a significant improvement of facial esthetics and skeletal relationship. By long-term face mask therapy for 9 months, there was little postoperative relapse of maxilla in this case.<br>SBG and prolonged postsurgical face mask therapy are likely to improve postoperative skeletal stability in the sagittal dimension after maxillary DOG in CLP patients.
