医原性異物に関連して発症した上顎洞放線菌症の1例 A case of actinomycosis in the maxillary sinus secondary to an iatrogenic foreign body
We encountered a rare case of actinomycosis in the maxillary sinus secondary to an iatrogenic foreign body.<BR>A 32-year-old man was referred to our hospital for evaluation and treatment of nasal obstruction. The clinical diagnosis was odontogenic maxillary sinuitis. Under general anesthesia, a radical sinusotomy of the right maxillary sinus and apicoectomy of the right maxillary second premolar were performed. We found necrotic tissue and an iatrogenic foreign body with sulfur granules at the bottom of the maxillary sinus. Histopathological examination revealed the presence of actinomyces. The histopathological diagnosis was actinomycosis.<BR>The postoperative course has been uneventful as of 20 months after operation.
