Risus Sardonicus is a facial expression often found in people with increased contraction of facial muscles. It is typically found in a disease condition we all at one time or the other must have heard about. You must have been told to treat open wounds and not walk with your bare feet if you have an open wound to prevent the disease “Tetanus”. The resulting facial expression, also known as the ‘Sardonic smile’ is a reaction contrary to what the patient feels. The patient has this wide grin on his face; usually mistaken to be scornful.
