Cluster headache: review of the literature

All papers on cluster headaches were reviewed according to preset criteria under the following headings: classification, epidemiology, aetiology, path ophysiology, and clinical features. The management review used the Cochrane systematic review guidelines and so is based on randomized controlled tria ls wherever possible. A meta-analysis was not done. Other treatments are di scussed and their drawbacks are highlighted and guidelines proposed based o n the evidence of this review. (C) 2001 The British Association of Oral and Maxillofacial Surgeons.
