摘要:

目的:探讨常用反映面部生长型的指标与后前面高比间的关系,验证后前面高比作为确定面部生长型指标的合理性。方法:选取61例生长发育期正常儿童头侧位X线片,测量后前面高比及包括Y轴角、颅底角、面部4 个矢状平面角、前下面高/前全面高、下颌支长等12项既往文献报道可用来反映面部生长型的指标,并进行统计学处理。结果:¹下颌平面角(MP-SN)与后前面高比有极高相关性,Pearson相关系数高达-01922;º面部4个矢状平面角与后前面高比呈负相关;»下颌支长度与后前面高比呈正相关。结论:确定面部生长型的敏感指标是面部后前面高比(S-Go/N-Me)及下颌平面角(SN-MP),后前面高比可作为确定面部生长型的指标。

Abstract:

Objective:This study aimed atfinding sensitive indicators in diagnosing facial growth pattern by studying the relationship be- tween the indicators which can reflectfacial growth pattern according to the previous studies and posterior-anterior ratio.Methods: The cephalometric radiographs of 61 teenage children were measured, the posterior-anterior ratio and the other 12 indicators in- cluding Y-axis angle, facial axis angle, cranial basal angle, and the four angles (The sagittal horizontal planeswere analyzed using statistic methods.Results:The MP-SN angle was significantly coincided with the posterior-anterior ratio and Pearson coefficient is -0.922, and little correlation was found between the angles of four sagittal horizontal planes and the posterior-anterior ratio. The positive correlation was found between the length of mandibular ramus and posterior-anterior ratio.Conclusion:The sensitive indi- cators for confirming facial growth pattern are the posterior-anterior ratio and the MP-SN angle.
