CT辅助下听眦线及鼻翼耳郭软骨下缘线对AC-PC平面的定位
Clinical study of AC-PC plane positioning between the Canthomeatal line and nosewing-auricle line assisted by CT
摘要
Abstract
Objective To study the measurement of AC-PC plane positioning between the Canthomeatal line and nosewing-auricle line assisted by CT,and to achieve delineating the AC-PC plane more accurately in the body surface.Methods By the 326 cases,measurement data who undergo stereotactic surgery of adult head in our hospital,to obtain the measurement of AC-PC line between the Canthomeatal line and nosewing-auricle line in the sagittal plane projection,the relative distance constant of AC-PC, the vertical distance in middle point of the external auditory canal to the AC-PC plane,in order to obtain the accurate AC-PC scan-ning plane.Results According the CT thick 2 mm layer scanning which parallelled to the canthomeatal line,AC-PC are all in the same level;according the CT thick 4 mm layer scanning which parallelled to the nosewing-auricle line,AC-PC are all in the same level.The average angle of canthomeatal line and AC-PC line is 1.6°±0.7°,the average length of AC-PC line is 48.4 mm±4.2 mm,the average angle of nosewing-auricle line and AC-PC line is 2.3°±0.3°,the average length of AC-PC line is 15.8 mm±2.8 mm,there are some obvious statistical difference between the two lines(P <0.05 ).Conclusion In the existing CT baseline,the clinical practicitabily of canthomeatal line and nosewing-auricle line are strong,nosewing-auricle line can be used as ideal CT scan-ning base line in the department of stereotactic and functional neurosurgery.关键词
