Abstract
• Twenty-eight consecutive patients with acute unilateral facial palsy were examined with special reference to clinical signs of central nervous system involvement. The clinical investigation in the acute stage of the disease showed that only seven patients had solitary facial nerve dysfunction, while the remaining patients had evidence of more widespread disease involvement. The most frequent finding was a trigeminal dysfunction of the paretic side, as shown by paresthesia and sensibility disturbance corresponding to the sensoritrigeminal area, as well as a dysfunction of the trigeminal component of the corneal reflex of the paretic side. Three patients showed migrating symptoms that were suggestive of a brain-stem disorder. In addition, four patients had an optic neuropathy, while an abnormal brain-stem audiometry response was demonstrated in five patients. The outcome of acute facial palsy one to two years after onset, however, could not be predicted from the clinical central nervous system signs. The degree of the palsy in the acute stage of the disease still seemed to be one of the most important prognostic factors. It is concluded that acute facial palsy is not a single entity, but rather a feature of different neurologic conditions.
