Facial pain: clinical differential diagnosis.
Differential diagnosis of pain in the face as the presenting complaint can be difficult. We propose an approach based on history and neurological examination, which allows a working diagnosis to be made at the bedside, including aetiological hypotheses, leading to a choice of investigations. Neuralgias are characterised by stabs of short lasting, lancinating pain, and, although neuralgias are often primary, imaging may be needed to exclude symptomatic forms. Facial pain with cranial nerve symptoms and signs is almost exclusively of secondary origin and requires urgent examination. Facial pain with focal autonomic signs is mostly primary and belongs to the group of the idiopathic trigeminal autonomic cephalalgias, but can occasionally be secondary. Pure facial pain is most often due to sinusitis and the chewing apparatus, but also a multitude of other causes. The pain can also be idiopathic. Imaging as well as non-neurological specialist assessment is often necessary in these cases.
