摘　　要：目的探讨过矫正鼻翼基底缩窄缝合技术应用于骨性Ⅲ类错[牙合]畸形正畸-正颌联合治疗前后鼻软组织形态的变化。方法选择24例行正畸-正颌联合治疗的骨性Ⅲ类错[牙合]畸形患者为对象。正颌术中应用过矫正鼻底缩窄缝合技术。分别于正颌术前、术后1周及术后1年行CBCT扫描。利用Mimics 17.0软件测量鼻尖角、鼻翼基底宽度、鼻小柱高度、鼻翼宽度、鼻背长度。比较其治疗前后的差异。结果术后1周较术前相比鼻翼宽度平均减小了(1.23±0.34)mm,鼻翼基底宽度平均减小了(1.22±0.44)mm。术后1年较术前鼻翼宽度平均增加了(0.57±0.58)mm,鼻翼基底宽度平均增加了(0.82±0.28)mm。术后1年较术后1周鼻翼宽度平均增加了(1.8±0.61)mm,鼻翼基底宽度平均增加了(2.04±0.51)mm。差异均具有统计学意义(P<0.01)。结论过矫正鼻底缝合技术对骨性Ⅲ类错[牙合]畸形患者行上颌骨LeFortⅠ型截骨前徙术后鼻底宽度有较好的控制,但仍然有增加的趋势。而鼻尖角、鼻小柱高度及鼻背长度基本稳定。Objective To investigate the morphological changes of nasal soft tissue before and after the application of over correction alar base narrowing suture technique in the treatment of skeletal ClassⅢmalocclusion.Methods Twenty four patients with skeletal ClassⅢmalocclusion who underwent orthodontic and orthognathic treatment were selected.In orthognathic surgery,the technique of nasal alar base over correction narrowing suture was used.CBCT scan was performed before orthognathic surgery,one week and one year after orthognathic surgery.The nasal cusp angle,alar base width,columella height,alar widest distance and nasal dorsal length were measured by Mimics 17.0 software.The differences before and after treatment were compared.Results One week after operation,the width of nasal alar decreased by(1.23±0.34)mm and the width of nasal alar base decreased by(1.22±0.44)mm.One year after operation,the width of nasal alar increased by(0.57±0.58)mm and the width of nasal alar base increased by(0.82±0.28)mm.One year after operation,the width of nasal alar increased by(1.8±0.61)mm and the width of nasal alar base increased by(2.04±0.51)mm.The differences were statistically significant(P<0.01).Conclusions The over correction nasal floor suture technique could control the width of nasal floor in patients with skeletal ClassⅢmalocclusion after LeFort Ⅰ osteotomy.The height of nasal tip,columella and length of nasal dorsum were stable.
