抄録

A case of nonclostridial gas-producing phlegmon in the mouth floor and neck of a young healthy patient is reported. A 24-year-old man had swelling and pain on the right submandibular region. Two days before admission to our hospital, he had pain and swelling of right lower molar region. On the next day, a swelling and spontaneous pain developed at the right submandibular region with pyrexia after 6 had been extracted by the patient himself. A clinical diagnosis of oral floor phlegmon was made. Antibiotic treatment was initiated intravenously. Three days later, he complained of dyspnea. Computed tomography (CT) revealed extension of gas bubbles in the soft tissue. Emergency tracheostomy and surgical drainage were performed. He recovered uneventfully and was discharged after 45 days.
Early detection of gas bubbles by CT, complete surgical drainage and administration of antibiotics are considered the most important factors in treating gas-producing phlegmon.
