Risus sardonicus
Introduction
Risus sardonicus is a highly characteristic, abnormal, sustained spasm of the facial muscles that is most often observed as a symptom of tetanus. The name of the condition derives from the appearance of raised eyebrows and an evil, open grin that it gives to its victim. Also poisoning with strychnine may result in a risus sardonicus.
