摘　　要：目的探讨不同的耳点选择对Tweed三角FMIA值的影响。方法对41例头颅定位侧位片分别测量解剖耳点、机械耳点所确定的不同的FH平面,分别测量FMIA值。结果不同的耳点选择对FMIA值得结果有显著性差异。结论不同的耳点影响FMIA值的结果。Objective To detect the effect on FMIA of Tweed Angle between anatomical Porion （Po-a） and mechanical Porion （Po-m）. Methods FH planes were defermined using two different Porions with 41 cephalometrie radiographs of lateral head films. FMIA were measured. Results Significant differences were found in measurements of FMIA. Conclusions Dfferent porion affects FMIA measurements.
