A case of nasopharyngeal actinomycosis leading to otitis media with effusion

Nasopharyngeal actinomycosis is extremely rare, and to our knowledge, only seven cases have previously been reported. Diagnosis of actinomycosis is made by clinical finding, observation of the bacteria and histopathological examination. Treatment for actinomycosis is surgical debridement and administration of antibioticus, especially penicillin for several weeks with good prognosis. We report a case of nasopharyngeal actinomycosis, which lead to otitis media with effusion. Endoscopic surgery and prolonged penicillin administration for 2 months were effective for treatment of actinomycosis in the nasopharynx.
