title: Facial growth in patients with unilateral clefts of the lip and palate: a two-center study.
abstract: Two groups of 10-year-old patients with complete unilateral clefts of the lip and palate were examined in this study. Two centers; Bristol, U.K. and Oslo, Norway, who had different treatment regimens were used. The groups comprised 40 patients from Oslo and 32 from Bristol. The groups were matched, in proportion to the size of the groups, for age, sex, and presence of Simonart's bands. In Oslo, a Millard lip repaired was performed at 3 months of age with a von Langenbeck palatal repair at 18 months, no presurgical orthopedics was employed and there was no primary nasal correction. The Bristol center also repaired the lip at 3 months with a Millard type repair but also performed a radical nasal correction at the same time. The palate was repaired at 6 months with a Veau repair, and presurgical orthopedics using a pinned arch orthopedic plate was carried out. In addition, the volume of primary repairs per surgeon was much higher in Oslo, and a much stricter treatment protocol was used compared with Bristol. Lateral cephalograms obtained within 1 year of the child's tenth birthday were digitized, and the craniofacial morphology of the two groups was compared. Significant differences in maxillary growth and soft tissue profile were noted with a much more retruded mid-face and flatter nasiolabial angle in the Bristol group. The main factors for the better results in Oslo are suggested to be the absence of presurgical orthopedics, no radical nasal correction, the high volume of operations performed per surgeon, and the stricter protocol.
