![]() ![]() Pierre Robin Sequence is an embryological disturbance involving first and second branchial arches. Key words: Pierre Robin sequence, craniofacial growth, cephalometric tracings, cephalometric measurements, osteogenic distraction. PRS patients not subjected to OD were found to be under the ranges established by cephalometric norms. The values for facial depth were altered (Po-Or/N-Pg) and found to be under the norm in all 10 studied cases. Angle C II was the predominating skeletal pattern. Growth behavior of the upper jaw showed tendency to verticality, and was apparent in 80% of cases as supra-occlusion and retrusion. At 7 years of age, a patient showed tendency to normality and at 8 years of age growth was horizontal. In patients 4, 5, 6 and 12 years old, growth was vertical. Growth behavior in patients without OD presented tendency towards verticality. A p < 0.05 significance level Mann Whitney U test was used. The main researcher performed 220 cephalometric tracings in lateral x-rays of the skull, previously Kappa test calibrated, Harvold, Ricketts, Riedel and Jarabak cephaolmetric analysis measurements were included in the study. The study was conducted on 10 PRS patients not subjected to OD. ![]() The study was descriptive, open, observational and retrospective. Manuel Gea González, Mexico City, Mexico.Ī craniofacial growth study was conducted in Pierre Robin Sequence patients (not subjected to osteogenic distraction) (OD), with the aim of assessing the behavior of partial compensatory growth of the upper and lower jaw structures, and thus determine whether this growth can be considered within the parameters of established cephalometric standards. ¶ Professor, Reconstructive and Plastic Surgery Division II Academic Coordinator, Orthodontics Specialty. § Head, Stomatological-Orthodontic Division. * Student, Graduate School of the National School of Dentistry, National University of Mexico, 3rd year student in Orthodontics.
