A 31-year-old male patient reported with a chief complaint of a forwardly placed lower jaw. Oral examination revealed Angle's Class III relationship bilaterally and cephalometrically; the patient presented with a small-sized retrognathic maxilla and normal mandible. Orthosurgical treatment was carried out with 4 mm of maxillary advancement and 4 mm of mandibular setback to achieve ideal overjet, overbite, and intercuspation of teeth. The ANB angle showed a drastic change from -9.5° to 1° and a successful conversion of the skeletal profile from Class III to Class I. Orthosurgical treatment can thus be an effective means of treating a patient with cleft lip and palate but requires a detailed understanding of the case and a sound diagnosis to attain a successful outcome.
一名31岁男性患者因下颌前突为主诉前来就诊。口腔检查双侧及头影测量显示安氏III类关系;患者上颌后缩且尺寸较小,下颌正常。进行了正颌外科治疗,上颌前徙4mm,下颌后退4mm,以实现理想的覆盖、覆合及牙齿尖窝关系。ANB角从-9.5°急剧变化至1°,骨骼侧貌成功从III类转变为I类。因此,正颌外科治疗可以是治疗唇腭裂患者的有效手段,但需要对病例有详细了解并做出准确诊断才能取得成功结果。
