title: Oropharyngeal carcinoma presenting as an odontogenic infection with trismus.
abstract: Severe odontogenic infections involving muscles of mastication are often accompanied by trismus at the initial presentation. On rare occasions a nasopharyngeal tumor will have trismus as a presenting symptom. We report a case of odontogenic infection requiring emergency management in which trismus did not resolve. On further investigation, a nasopharyngeal carcinoma was diagnosed.
