摘要
目的研究双侧下颌升支矢状劈开截骨术(BSSRO)对男性下颌前突患者舌骨位置和咽气道间隙的影响,探讨BSSRO与阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的关系。方法选择2012-2017年于中国医科大学附属口腔医院行BSSRO的男性下颌前突畸形患者30例作为病例组,分别于术前、术后1~2周及术后6~12个月拍摄头颅侧位片;选择同期具有正常矢状骨面型的30例男性成年正畸治疗患者作为对照组,正畸治疗前拍摄头颅侧位片。AutoCAD软件测量上下颌骨位置、舌骨位置及咽气道间隙相关测量项目,比较分析病例组术前、术后的上下颌骨位置、舌骨位置和咽气道间隙的变化以及病例组与对照组之间的差异。结果病例组术后下颌骨后移。病例组术前与对照组相比,舌骨测量值中舌骨体最前上点(H点)到X轴的垂直距离(H-X)、H点到下颌平面的垂直距离(H-MP)显著减小(P <0.05),H点到第三颈椎最前下点(C3点)的距离(H-C3)显著增加(P <0.05);咽气道测量值中腭垂尖至中咽壁点距离(U-MPW)、下颌骨后下缘与舌背交点到咽后壁距离(MT-MTP)、过会厌最上点(E点)咽腔间隙距离(EPA-EPP)显著增加(P <0.05)。病例组术后1~2周及术后6~12个月与术前相比,H-X、H-MP显著增加,H-C3显著减小,U-MPW、MT-MTP、EPA-EPP显著减小(P <0.05);术后6~12个月与术后1~2周相比,H-X显著减小,H-C3显著增加,U-MPW、MT-MTP显著增加(P <0.05)。病例组术后6~12个月与对照组相比,反映舌骨位置和咽气道间隙的各项指标差异均无统计学意义(均P> 0.05)。结论男性下颌前突患者行BSSRO术后短期内舌骨位置向后下移位,咽气道间隙减小,随时间推移,逐渐回复到正常范围,提示男性下颌前突患者行BSSRO术后发生OSAHS的风险不大。
Objective To explore the relationship between bilateral sagittal split ramus osteotomy(BSSRO)and obstructive sleep apnea hypopnea syndrome(OSAHS)by studying the effect of BSSRO on hyoid bone position and pharyngeal airway space in male patients with mandibular prognathism.Methods A total of 30 male patients with mandibular protrusion who underwent BSSRO in Hospital of Stomatology,China Medical University,were selected as csae group,and lateral cephalogram was taken respectively before operation and 1-2 weeks and 6-12 months after operation.A total of 30 male adult patients with normal sagittal facial type undergoing orthodontic treatment were used as control group.Lateral cephalogram was taken before orthodontic treatment.Auto CAD was used to measure hyoid bone position and pharyngeal airway space.Changes before and after operation were compared and analyzed in the case group,and the differences was compared between the case group and the control group.Results Compared with the control group,the preoperative hyoid bone measurement indexes of the case group were statistically different(H-X and H-MP significantly decreased,while H-C3 significantly increased,P<0.05);the preoperative pharyngeal airway space measurement indexes of the case group were also statistically different(U-MPW,MT-MTP and EPA-EPP significantly increased,P<0.05).In the case group,compared with preoperative indexes,the hyoid bone measurement indexes(H-X and H-MP significantly increased,H-C3 significantly decreased)and the pharyngeal airway space measurement indexes(U-MPW,MT-MTP and EPA-EPP significantly decreased)in postoperative 1-2 weeks(P<0.05).Compared with the indexes in postoperative 1-2 weeks,H-X significantly decreased,H-C3 significantly increased,U-MPW and MT-MTP significantly increased in postoperative 6-12 months(P<0.05).The difference in each index reflecting the hyoid position and pharyngeal airway space between the case group in postoperative 6-12 months and the control group had no satistical significance(P>0.05).Conclusion In male
