Rigid fixation of the craniofacial skeleton has proven of great value in adult orthognathic and traumatic reconstructive surgical procedures. This technique has gained increased acceptance in the surgical treatment of infants and young children with congenital malformations, despite the fact that its effects on subsequent craniofacial growth are unknown. To examine this question, an experimental model using 25 young kittens was developed to compare rigid fixation with conventional wire fixation, with and without osteotomy. Our findings demonstrate a regional restriction of growth in the developing craniofacial skeleton when both wire and plate and screw fixation are utilized in concert with osteotomy. Further, a compensatory growth was observed in individual animals when plate fixation was utilized that was not seen in the wire-treated group. This suggests that there is a dynamic growth interaction between restriction and compensation in this setting.
颅面骨骼的坚固固定已在成人正颌和创伤性重建外科手术中证明具有重大价值。尽管其对后续颅面生长的影响尚不清楚，但该技术在先天性畸形婴幼儿的外科治疗中已得到越来越多的认可。为研究这个问题，我们建立了一个使用25只幼猫的实验模型，以比较坚固固定与传统钢丝固定在有截骨和无截骨情况下的效果。我们的研究结果表明，当钢丝以及钢板和螺钉固定与截骨术联合使用时，发育中的颅面骨骼生长会受到局部限制。此外，在使用钢板固定的个体动物中观察到了代偿性生长，而在钢丝治疗组中未观察到这种情况。这表明在这种情况下，限制与代偿之间存在动态生长相互作用。
