Below is the abstract of an article that reviewed the clinical outcomes of several patients who underwent nerve decompression surgery for nerve compression headache. Some patients did very well, and some did not experience relief. The article is available online. Link to article
Background: The therapeutic benefit of nerve decompression surgeries for chronic headache/migraine are controversial.
Aim: To provide clinical characteristics of headache type and treatment outcome of occipital nerve decompression surgery.
Methods: A retrospective review of clinical records. Inclusion criteria were evidence of chronic occipital headache with and without migrainous features and tenderness of neck muscles, occipital allodynia, and inadequate response to prophylactic drugs.
Results: Surgical decompression of the greater and lesser occipital nerves provided complete and extended (3-6 years) relief of new daily persistent headache in case 3 (46 year old female), and of chronic post-traumatic headache in cases 4 and 6 (35 and 30 year old females, respectively), partial relief of chronic headache/migraine in cases 1 and 2 (41 year old female and 36 year old male), and no relief of episodic (cases 3 and 4) or chronic migraine (case 5, 52 year old male), or chronic tension-type headache (case 7, 31 year old male).
Conclusions: As a case series, this study cannot test a hypothesis or determine cause and effect. However, the complete elimination of new daily persistent headache and post-traumatic headache, and the partial elimination of chronic headache/migraine in two patients – all refractory to other treatment approaches – supports and justifies the effort to continue to generate data that can help determine whether decompression nerve surgeries are beneficial in the treatment of certain types of chronic headache.
