蝶枕软骨融合阶段评估颌骨发育的相关进展

Research Progress on Spheno-Occipital Synchondrosis Maturation Stages in Maxillomandibular Growth

摘要: 蝶枕软骨融合阶段是评估青少年颅颌面发育的重要手段，其通过CBCT进行骨龄的分期。目前常用的分期法有四阶段、五阶段和六阶段三种方法。多位学者证实SOS融合阶段与目前临床中常用的手腕骨龄和颈椎骨龄均有较强的相关性。颌骨与下颌骨的发育高峰期，若采用4阶段分期法一般出现在SOS2~SOS3，若采用6阶段分期法则出现在SOS3~SOS5，上颌骨周围骨缝的成熟度与SOS融合阶段有显著的正相关性。未来需要制定更为统一的标准及更多的临床研究完善该分期法。

Abstract: Spheno-occipital synchondrosis maturation stage is an important means to evaluate craniofacial development of adolescents, and its bone age is staged by CBCT. At present, there are three commonly used staging methods: four-stage, five-stage and six-stage. Most scholars have confirmed that SOS fusion stage is strongly correlated with wrist bone age and cervical bone age commonly used in clinical practice The peak of jaw and mandible development generally occurs in SOS2~SOS3 if the 4-stage staging method is adopted, and in SOS3~SOS5 if the 6-stage staging method is adopted, the maturity of the suture around the maxilla is significantly positively correlated with the SOS fusion stage. In the future, more unified standards and more clinical research are needed to improve this staging method.
