Hemifacial microsomia and Treacher Collins syndrome are the most frequent among the first and second branchial arch syndromes to include anomalies of the facial skeleton. Hemifacial microsomia is almost always unilateral and is characterised by hypoplasia or agenesis of the mandibular ramus. Treacher Collins syndrome is always bilateral and involves specifically the zygomatic bones. The treatment of skeletal anomalies is seldom started before 10-12 years of age, except in severe form with major aesthetic impairment. Such cases are treated at the beginning of school age, on and after 6-8 years. Several operations, including osteotomies of the jaws and bone grafts, are usually necessary to achieve an acceptable result.
半侧颜面短小畸形和特雷彻·柯林斯综合征是第一和第二鳃弓综合征中最常见的，包括面部骨骼异常。半侧颜面短小畸形几乎总是单侧的，其特征是下颌支发育不全或缺失。特雷彻·柯林斯综合征总是双侧的，特别累及颧骨。骨骼异常的治疗很少在10至12岁之前开始，除非是严重形式且有严重美学缺陷的情况。这种情况在学龄初期，即6至8岁及之后进行治疗。通常需要进行几次手术，包括颌骨截骨术和骨移植，以获得可接受的效果。
