Intact Corneomandibular (Wartenberg) Reflex Patient with pontine hemorrhage without impaired consciousness - Left corneal stimulation triggers contralateral jaw deviation due to contraction of the ipsilateral pterygoid muscles. A prominent unilateral left corneomandibular reflex was observed and the patient was conscious and responsive to the examiner. This reflex consists of contralateral jaw deviation produced by corneal stimulation and has mostly been described in patients in coma. It helps to distinguish structural from metabolic processes in comatose patients. We emphasize that this sign can also be elicited in alert patients with destructive brainstem damage. #Corneal #Corneomandibular #Reflex #Intact #PhysicalExam #clinical #Neurology #Video #Wartenberg
