Study Notes

Gow-Gates Mandibular Nerve Block Technique

The Gow-Gates mandibular nerve block is a "high" method of anesthetizing the inferior alveolar nerve.
It can block transmission in many accessory supplies to the dental pulps, including those provided by the lingual, long buccal, mylohyoid, and auriculotemporal nerves.
Nerves anesthetized include the inferior alveolar, mental, incisive, lingual, mylohyoid, auriculotemporal, and buccal (in 75% of patients).
The direction of the needle involves drawing a line from the corner of the mouth to the insertion line or in an upward direction in the y-axis.
The area of insertion for the Gow-Gates technique is the mucous membrane on the mesial of the mandibular ramus, just distal to the maxillary second molar.
The technique involves the patient's mouth being kept open wide during the injection.
The average depth of soft tissue penetration to bone during the injection is 25 mm.
The time to onset of anesthesia for the Gow-Gates technique is somewhat longer (5 minutes) than for an Inferior Alveolar Nerve Block (3 to 5 minutes).
The Akinosi-Vazirani block is also a "high" block and is often referred to as the closed mouth technique.
The Akinosi-Vazirani block is indicated when the patient can't open their mouth or has a large tongue obstructing the view of landmarks.
The entry point for the Akinosi-Vazirani block is the same as the Gow-Gates technique, but the target area is different.
The mouth is closed during the Akinosi-Vazirani block injection.
