Severe midface and maxillary hypoplasia can have an impact on an individual, either on the appearance, functions or psychologically. Based on literature review, severe maxillary hypoplasia with more than 25.0 mm reverse overjet in non-cleft and non-syndromic patients is very rare. It is more often seen in cleft lip and palate and syndromic patients. When the magnitude of correction exceeds the limit of what a single orthognathic surgery can achieve, multiple surgeries would be required, involving different surgical techniques. The authors report two rare cases of non-syndromic nor cleft severe hypoplastic midface and maxilla with 26.0 mm and 27.0 mm reverse overjet, respectively, treated with 2-stage surgery involving maxillary distraction osteogenesis and orthognathic surgery. Both cases recorded reasonably clinical and functional outcomes. The significance of both surgical interventions is further discussed.
严重的面中部和上颌骨发育不良会对个体产生影响，无论是在外观、功能还是心理方面。根据文献回顾，在非唇腭裂和非综合征患者中，超过 25.0 毫米的上颌后缩反颌是非常罕见的。这种情况更常见于唇腭裂和综合征患者中。当矫正幅度超过单颌正颌手术所能达到的极限时，就需要进行多次手术，涉及不同的手术技术。作者报告了两例罕见的非综合征性或非唇腭裂严重面中部和上颌骨发育不良的病例，上颌后缩反颌分别为 26.0 毫米和 27.0 毫米，采用了涉及上颌骨牵引成骨和正颌手术的两阶段手术进行治疗。两例病例均记录了较为合理的临床和功能结果。进一步讨论了这两种手术干预的意义。
