Maxillary Block Injection-High Tuberosity Approach

Check out our latest video of the maxillary nerve block injection technique. 

Technique: Same as the PSA injection (distal to second molar with 45, 45, 45 angles) but with a long needle inserted 3/4 the length. 

Pros- 1 injection numbs the maxillary quadrant reducing the amount of injections needed. 

Cons- Increased chance of hitting the plexus and is doesn't reduce hemostasis as well. Some supplementary injections still may be needed.
