ReviewRegional anesthesia and invasive techniques to manage head and neck pain.
Regional anesthesia of the head and neck is an effective method of obtaining surgical anesthesia for various procedures. Diagnostic and therapeutic head and neck blocks can also assist with the diagnosis and management of many chronic pain conditions, including headache, postherpetic neuralgia, and cancer pain in this region. ⋯ Because of the proximity of so many critical structures adjacent to these nerves, a solid understanding of the anatomical basis of these nerve blocks is necessary. Appropriate patient selection, monitoring, proper injection technique, knowledge of the pharmacokinetics and pharmacodynamics of local anesthetics and vasoconstrictors, possible drug interactions, and recommended doses will ensure safe and successful application of head and neck nerve blockade.
