"Prepare the skin, disinfect, now determining the puncture point." Xie Wanying reported to her senior brother.
"Where do you want to start the puncture point?" Huang Zhilei asked.
"There are generally two approaches for lateral ventricle drainage. One is the frontal approach, 1 cm in front of the coronal suture, 2 to 2.5 cm lateral to the midline, with the puncture needle parallel to the sagittal plane, aiming at the line connecting the two external auditory canals. The other is the occipital approach, with the puncture point 6 to 7 cm above the external occipital protuberance, 3 cm lateral to the midline, also parallel to the sagittal plane, aiming at the brow ridge. Both have a depth of about 5 cm."
"Hmm hmm." Huang Zhilei nodded, the junior sister's foundation is very good, like a textbook-style answer. Based on the guidance of book knowledge, what will the junior sister's decision be? With both approaches available, how does a doctor choose?
