Gow-Gates technique for mandibular nerve block

Steps: * The mouth is opened as wide as possible * Insert the needle high into the mucosa at the level of the 2nd maxillary molar just distal to the mesiolingual cusp * Use the intertragic notch as an extraoral landmark to help reach the neck of the mandibular condyle * Advance the needle in a plane from the corner of the mouth to the intertragic notch from the contralateral premolars (this position varies in accordance with individual flare of the mandible) until it contacts the condylar neck * Withdraw the needle slightly and perform aspiration to observe whether the needle is in a blood vessel * After a negative result on aspiration, slowly inject the anesthetic * Have the patient keep the mouth open for a few minutes after injection, to allow the anesthetic to diffuse around the nerves By: https://www.instagram.com/p/CcTnp4BPseO/?igshid=YmMyMTA2M2Y=
