A 72-year-old man was referred to our hospital with a seven day history of left otorrhea and swelling of the neck despite conservative treatment. He had suffered from chronic otitis media and stenosis of the external auditory canal of the left ear following a traffic accident twenty years ago. A CT-scan revealed mastoiditis of the left ear and an abscess formed behind the left sternocleidomastoid muscle. Emergency drainage of the neck abscess was performed under local anesthesia. An anaerobic bacterium <i>Prevotella species</i> was cultured from the abscess.<br>Mastoidectomy and meato-tympanoplasty were performed under general anesthesia on the 44th day after the drainage operation, since diabetes mellitus and heart disease were not well controlled. The mastoid cavity was completely filled with granulation and a bone defect was found at the mastoid tip cell suggesting the propagation route of the infection. Postoperative courses were uneventful and the otorrhea did not recur.
