Migraine surgery is the only existing treatment option that can lead to a permanent symptomatic
improvement. Surgical techniques and advances in the understanding of the underlying mechanisms
are evolving rapidly. This book intends to familiarise surgeons with the concept of migraine
headaches and explains the surgical deactivation of trigger sites which consists of much more
than the decompression of pericranial nerves. The traditional notion of the brain as the sole
origin of migraine is supplanted by a concept where the alteration of afferent signals in
conjunction with peripheral and central sensitization can trigger a migraine attack. Migraine
surgery targets the crucial role of extracranial tissues in the genesis of migraine which is
corroborated by substantial clinical anatomical and pathophysiological evidence.
