【Location】On the face,in the depression between the zygomatic arch and the mandible notch.
【Manipulation Method】Puncture perpendicularly or obliquely 0.3-1 cun.
【Indications】Tinnitus,deafness,otopyorrhea,toothache,facial pain,deviated mouth,motor impairment of the jaw.
【Stratified anatomy】(Fig.1-16,Fig.1-17)
(1)Skin The skin is distributed by auriclotemporal n..
(2)Subcutaneous tissue There are branches of auriclotemporal n.,zygomatic branches of facial n.,branches or tributaries of transverse facial a. & v..
(3)Parotid gland The parotid gland is located in the anteroinferior of auricle,wrapped in the parotid sheath.
(4)Masseter The masseter is located in the deep surface of lateral ramus of mandible superficial fascia.
(5)Between temporalis and condylar process of mandible The temporalis is located in the deep surface of temporal fascia.
(6)Maxillary a. & v. The maxillary a.is one of the end branches of external carotid a.,The maxillary v.is the tributary of retromandibular v..
(7)Lateral pterygoid The lateral pterygoid is located in the infratemporal fossa.

【Cautions】There are the maxillary a.and v.on the deep surface of the acupoint.If the depth of perpendicular insertion is much deeper,the vessels can be injured.And there are the inferior alveolar n.,the lingual n.and the middle meningeal a.on the deep surface of the external pterygoid muscle of the acupoint.If the middle meningeal a.is needle-inserted,the heavy bleeding will occur.Hence,the acupoint cannot be inserted deeply for avoiding the vessels injury.
