14.Sibai（ST 2）

【Location】On the face，directly below the pupil，in the depression of the infraorbital foramen.

【Manipulation Method】Puncture perpendicularly 0.3-0.5cun，or puncture obliquely downward 1 cun.

【Indications】Pain and swelling in the eyes，twitching of eyelids，lacrimation with wind，cloudiness of the cornea，myopia，deviated mouth and eye，facial pain，headache，dizziness，biliary ascariasis.

【Stratified anatomy】（Fig.1-10）

（1）Skin The skin is distributed by infraorbital n..

（2）Subcutaneous tissue There are branches of infraorbital n.，zygomatic branches of facial n.，branches or tributaries of facial and infraorbital a. ＆ v..

（3）Orbicularis oculi and levator Iabii superioris The orbicularis oculi is located in the deep surface of superficial fascia around the rima oculi.The levator labii superiors is located in the deep surface of superficial fascia in infraorbital region and the upper fascicle is coverd by orbicularis oculi.

（4）Infraorbital foramen or maxilla The infraorbital foramen where the intraorbital vessels and nerves pass through is located in the position about 0.8cm under the midpoint of the intraorbital margin.

【Cautions】The deep surface of the acupoint is directly facing the infraorbital foramen and extends inward to the intraorbital canal and the infraorbital groove.If the depth of perpendicular insertion is much deeper passing through the intraorbital foramen into the intraorbital canal，the intraorbital a.and v.within the intraorbital canal can be needle-inserted extremely easily and the ecchymosis of eyelid is occurred.Hence，the depth shall not be so deeper that perpendicular needle-inserting damages the vessels.While removing the needle，there shall be with a gentle manner and half minute’s pressing of cotton ball for avoiding bleeding.
