Cephalic tetanus is a rare form of tetanus defined as trismus plus paralysis of one or more cranial nerves. The most frequently involved cranial nerve is the seventh. It accounts for 1 to 3% of the total number of reported cases of tetanus and has a mortality of 15 to 30%. The incubation period is 1 to 14 days, and approximately two thirds of cases progress to generalized tetanus. The mechanism of the paralysis is not completely understood. Treatment involves debridement of wounds, administration of penicillin and tetanus immune-globulin, aggressive supportive care, and initiation of active immunization.
