ABSTRACT
A systematic search of the available literature was performed using Medline, Embase, Cochrane library and NHS Evidence. The diagnosis of facial pain is complex, requiring a holistic approach to the patient. Individuals are often convinced or have been convinced, either by reading the internet or by their family doctor, that their facial symptoms have underlying sinus aetiology. Reaching the correct diagnosis in patients with facial pain is challenging because many patients come with fixed ideas about the cause of their pain. Pain is defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage. Migraine is characterized by recurrent, often unilateral, moderate to severe headaches, which may be associated with a number of symptoms attributable to the autonomic nervous system. Cluster headaches are excruciating unilateral headaches of extreme intensity affecting the frontal and temporal regions, extending over the cheek and even into the teeth.
