摘要

一名25岁的女性患者出现左侧髁突增生、面部悬垂型不对称、下颌前突和牙弓宽度不一致。骨闪烁扫描证实髁状突处于非活动状态,颞下颌关节功能也在正常范围内,因此进行了不切除髁状突的正颌手术。要通过正颌手术成功矫正面部不对称,必须在术前正畸阶段实现充分的牙槽骨减压。在悬雍垂型面部不对称的病例中,非偏斜侧的牙齿被挤出作为牙槽骨补偿。因此,挤出的牙齿需要垂直减压才能嵌入。使用微型螺丝刀和树脂堆积物进行牙齿嵌入,并在正颌手术的同时进行后段截骨术,以进一步嵌入牙齿。通过成功的垂直减压以及正畸医生和颌面外科医生之间的密切合作,悬垂型面部不对称得到了显著矫正。经过两年的保留,治疗效果保持稳定。

Unilateral condylar hyperplasia treated with simultaneous 2-jaw orthognathic surgery and posterior segmental osteotomy.

A 25-year-old woman presented with left condylar hyperplasia, canting-type facial asymmetry, mandibular prognathism, and arch width discrepancy. Bone scintigraphy confirmed the inactive status of the condyle, and the temporomandibular joint functioned within the normal range; thus, orthognathic surgery without condylectomy was performed. To correct facial asymmetry successfully through orthognathic surgery, sufficient dentoalveolar decompensation must be achieved in the presurgical orthodontic phase. In cases of canting-type facial asymmetry, teeth on the nondeviated side are extruded as dentoalveolar compensation. Therefore, vertical decompensation is required for intrusion of the extruded teeth. A miniscrew and resin build-ups were used for the intrusion of teeth, and posterior segmental osteotomy was simultaneously performed with orthognathic surgery for further intrusion. The canting-type facial asymmetry was notably corrected through successful vertical decompensation and close cooperation between orthodontists and maxillofacial surgeons. After 2 years of retention, the treatment results remained stable.
