Dentocraniofacial morphology in unilateral and bilateral cleft lip and palate following labioplasty and palatoplasty; analysis at first and second cervical vertebral maturation stage

To evaluate dentocraniofacial morphology of children with complete unilateral and bilateral cleft lip and palate following labioplasty and palatoplasty. Analysis was made when the children were at first and second stages of cervical vertebral maturation stage, before the peak of maxillary growth. Materials and methods: Sixteen digital cephalometric images of subjects with complete unilateral and bilateral cleft lip and palate following labioplasty and palatoplasty were compared with 16 normal stage-matched controls. Cervical vertebral maturation stage was determined by Method of Baccetti et al (2002). Statistics included tests for normal distribution, paired t test, and anova with the significance level p < .05. There were significant cephalometric differences in UI / Mx Plangle between unilateral and control; ANB angle, SN / MP angle, UI/MxPlangle between bilateral and normal; SNA angle, UI/MxPl angle between unilateral and bilateral group. The inclination of upper incisor was most affected by cleft lip and palate.The maxilla inclination was found a little retrusive for unilateral cleft lip and palate, while a little protrusive for bilateral. Sagittal relationship of bilateral was found the most protrusive followed by normal and unilateral group. Mandibular steepness was found for bilateral cleft lip and palate.
