We report three patients with tetanus who complained of dysphagia. All cases showed trismus, however, physical, serological and endoscopic examinations revealed not abnormalities. Under the diagnosis of tetanus, intravenous penicillin was administered to all three cases, which resulted in the disappearance of trismus, although one case showed a brief episode of generalized convulsion. The diagnosis of tetanus should be suspected in patients complaining of dysphagia who are found to have trismus, but no accompanying endoscopic findings.
