Based on longitudinal observation of more than 80 patients, we concluded that mandibular hypoplasia is the earliest skeletal manifestation of hemifacial microsomia. The clinical defect becomes worse with time as a result of continued asymmetric growth and progressive secondary deformation of the midface. We hypothesize that midface growth is restricted by the hypoplastic mandible. Therefore, early elongation of the mandible should result in a more symmetrical growth pattern by eliminating mandibular restriction and creating a space for vertical midface growth.
基于对80多名患者的纵向观察，我们得出结论：下颌发育不全是半侧颜面短小畸形最早出现的骨骼表现。由于面部持续不对称生长和中面部继发性渐进性变形，临床缺陷会随时间加重。我们推测中面部生长受到发育不全的下颌骨限制。因此，早期延长下颌骨应能消除下颌骨限制并为中面部垂直生长创造空间，从而产生更对称的生长模式。
