统的下牙槽神经阻滞是把麻药注射于下颌孔及其附近,以麻醉下齿槽神经和舌神经;阻滞颊神经则需在磨牙后凹和/或颊后穹隆注射。一般认为,麻药注射点距神经越近越好。Gow-Gates则认为麻药注射点距神经尚有一定距离时仍能获得满意的麻醉效果,因此他提出一种把麻药注射在髁状突颈部内侧的新方法——Gow-Gates法。本文着重分析这种新方法的解剖基础。 Gow-Gates法的操作方法:请患者大张口,从翼突颞骨三角顶端进针;注射器须平行于口角至注射侧耳屏下缘的联线,对准髁状突前内侧,朝后上行进直达骨面,然后注射麻药。
Systemic inferior alveolar nerve block is the anesthetic injection in the mandibular orifice and its vicinity, in order to anesthetize the alveolar nerve and lingual nerve; block the buccal nerve in the molar and / or buccal dome injection. It is generally believed that the closer the anesthetic injection point is to the nerve, the better. Gow-Gates believes that anesthesia injection points can still get a satisfactory anesthetic effect at a certain distance from the nerve. Therefore, he proposed a new Gow-Gates method that injects anesthetic into the inside of the condyles neck. This article focuses on the anatomical basis of this new approach. Gow-Gates method of operation: patients with large mouth, from the top of the triangular process of the temporal pancreas into the needle; syringe to be parallel to the injection side of the trailing edge of the trailing edge of the line, aligned medial condyle forward, Bone surface, and then injected anesthetic.
