case_images: Once anesthesia was effective, 0.5-0.8 cm incision was made on the scalp (Figure 1(a)). A manual skull driller was used to drill through the scalp and skull (Figure 1(b)), and hematoma was aspirated as much as possible using a brain puncture needle (Figure 1(c)). A 10 F drainage tube was inserted into the hematoma cavity (Figure 1(d)); then, the tube core was withdrawn and the drainage tube further inserted toward the hematoma for 1 cm.
