title: Horner'sy syndrome and its significance in the management of head and neck trauma.
abstract: The history, mechanism and aetiology of Horner'sy Syndrome is presented and the pharmacology of the pupil is discussed. The case reported is a rare combination of Horner's Syndrome in a patient who sustained bilateral fractures of the mandible and a chest injury. It is emphasised that the miotic changes in Horner's Syndrome, in combination with head injuries can lead to confusion in diagnosis and the potential anaesthetic hazards and their influence on the management of the facial injury are outlined.
