【摘要】 目的:通过测量因髁突肥大而接受髁突高位切除术患者的术前、术后面部软/硬组织偏颌指数(AI),观察软/硬组织偏斜改善的关联。方法:接受单侧髁突高位切除术的髁突肥大患者15例,观测术前及术后随访时,软组织耳屏前点、下颌角点(Go’)、颏点(Me’)与面中线和Go’-Me’,及硬组织髁突外侧点(Col)、下颌角点(Go)、颏点(Me)和Go-Me的距离。计算得出对应AI值。结果:手术前后测量值配对t检验。经耳屏前点与经髁突外侧点AI值相关系数r=0.933,下颌角(AI)r=0.984,下颌骨体(AI)r=0.997,颏点偏移r=0.997,下颌升支(AI)r=0.645,仅耳屏前点(AI)P>0.01。结论:单纯的髁突高位切除术可有效的改善偏颌畸形;面部软组织偏斜的矫正与硬组织的矫正之间有较高的相关性;面部软/硬组织下颌升支偏斜的改善不完全等效。更多还原

【Abstract】 Objective: This study aimed to measure the patients’ soft-and hard-tissue facial asymmetry indices before operation and follow-up after condylectomy,and evaluate the correction between them.Methods: 15 patients treated with unilateral high partial condylectomy were enrolled in this study.The distances between preaureculare,gonion(Go’),mesion point(Me’) to midsagittal line and Go’-Me’ in the soft-tissue,and corresponding point in the hard-tissue were measured.Statistical comparisons were performed with paired t-test and correlation Pearson-test between groups,after asymmetry indices(AI) were calculated.Results: In the paired t test,only the preauricular points(AI) were found P>0.01.The distance between preaureculare and condylar point to midsagittal(AI) correlation coefficient r=0.933,gonion(AI) r= 0.984,mandibular body(AI) r=0.997,mesion(AI) r=0.997and mandibular ramus(AI) r=0.645.Conclusion: Condylectomy operation can restore facial asymmetry effectively.Soft-tissue correction showed high coordination with the hard-tissues.Mandibular ramus deformity improvement is not completely equivalent to soft-and hard-tissue correction.更多还原
