Question

Needling ST-2 (sibai) with lifting and thrusting may injure?

1) the orbital vein
2) the sinus cavity
3) the infraorbital nerve
4) infratrochlear nerve

Answer 1

Needling ST-2 with lifting and thrusting can potentially injure the 3) infraorbital nerve due to its proximity to the infraorbital foramen.

Step-by-step explanation:

When performing acupuncture on ST-2 (sibai), which is located in the infraorbital region, care must be taken to avoid injury to anatomical structures. The correct option for the structure that may be injured with lifting and thrusting needle technique at this point is the infraorbital nerve. This is because ST-2 is situated near the infraorbital foramen, where the infraorbital nerve exits. Injury to other listed structures such as the orbital vein, sinus cavity, or infratrochlear nerve is less likely due to their anatomical locations relative to ST-2.
