【摘要】Objective To measure the normal width of the lateral ventricle of normal Chinese adults on CT-based forehead horn puncture coronal plane,and explore the optimal puncture direction through the forehead horn of the ventricle.Methods Original brain CT data of 241 Chinese adults,admitted to our hospital from October 2014 to september 2015,were collected and divided into 4 groups based on their ages,which were groups of less than 44 years old,45 to 59 years old,60 to 74 years old and more than 75 years old.The coronal planes were reconstructed on the CT images based on the puncture routes of forehead horn of the ventricle.The width of ventricle on the puncture side in this plane was measured.The standard puncture point was 2.5 cm aside from the midline of the head.On the reconstructed coronal plane,the angle between the line of the standard puncture point to forehead horn of the ventricle and the sagittal plane was named as lateral opening angle (LOA).The angle between the line of standard puncture point to the septum vertices and the sagittal plane was named as maximal lateral opening angle (maxLOA).The angle between the line
