A review of a surgical-orthodontic database revealed striking changes in the surgical treatment of skeletal Class III problems. After its development, ramus osteotomy for mandibular setback became the standard procedure and was still used in nearly half the patients treated in 1978 to 1985. Between 1985 and 1990, the number of isolated mandibular setback procedures dropped sharply, while the number of maxillary advancements nearly doubled. The number of patients undergoing combined maxillary and mandibular surgery also increased. In 1990 to 1992, isolated mandibular setback was used in fewer than 10% of the patients, while maxillary advancement was used in more than 40% of the patients. The changes were influenced by improvements in surgical techniques, the demonstration that maxillary advancement is unlikely to cause speech problems in noncleft patients, and documentation that better esthetics and stability can be achieved with maxillary than with mandibular surgery.
一项针对外科正畸数据库的回顾揭示了骨骼Ⅲ类问题外科治疗方面的显著变化。自其发展以来，下颌后缩的升支截骨术成为标准术式，在1978年至1985年接受治疗的患者中，近一半仍在使用该术式。1985年至1990年间，单纯下颌后缩手术的数量急剧下降，而上颌前徙术的数量几乎翻了一番。接受上颌和下颌联合手术的患者数量也有所增加。在1990年至1992年期间，接受单纯下颌后缩手术的患者不到10%，而上颌前徙术用于超过40%的患者。这些变化受到手术技术改进的影响，有证据表明上颌前徙术在非腭裂患者中不太可能导致语音问题，并且有文献证明上颌手术比下颌手术能实现更好的美观效果和稳定性。
