多剤耐性Enterobacter cloacaeによる歯性上顎洞炎の1例

抄録

Enterobacter cloacae infection of the maxillary sinus is very rare. The patient was a 66-year-old woman with a chief complaint of a painful swelling in the left cheek. She was referred to our hospital by a dental clinic. Bacteriological examination of pus obtained during root canal treatment revealed multidrug-resistant Enterobacter cloacae. We administered antibiotics, performed root canal treatment, and extracted the infected tooth to allow pus drainage and irrigation. After appropriate medical and surgical treatment, the patient’s clinical symptoms resolved.
