Literature Review: Pericranial Nerve Blocks for Chronic Migraines

Area of Science:

• Neurology
• Pain Management
• Minimally Invasive Procedures

Background:

• Headaches, especially migraines, are prevalent neurological disorders impacting a significant portion of the population.
• Current treatment modalities include lifestyle adjustments, pharmacological interventions, and minimally invasive techniques like peripheral nerve stimulation (PNS) and pericranial nerve blocks (PNBs).

Purpose of the Study:

• To review recent literature on the efficacy of pericranial nerve blocks (PNBs) for migraine treatment.
• To provide a concise overview of peripheral nerve stimulation (PNS) as a related therapeutic option.

Main Methods:

• Review of recent scientific literature on pericranial nerve blocks (PNBs) and their application in migraine management.
• Focus on studies evaluating the efficacy of various PNBs, including the greater occipital nerve block (GONB).

Main Results:

• Pericranial nerve blocks (PNBs), utilizing local anesthetics with or without corticosteroids, are employed for migraine treatment and prevention.
• The greater occipital nerve block (GONB) is the most studied PNB, demonstrating efficacy for migraines, trigeminal neuralgia, and several other headache types.
• PNBs are not effective for medication overuse headaches or chronic tension-type headaches.

Conclusions:

• Pericranial nerve blocks (PNBs) represent a valuable therapeutic option for managing various headache disorders, with the greater occipital nerve block (GONB) being a prominent example.
• Further research into PNBs and PNS can refine treatment strategies for headache patients.
