[Chronic cutaneous fistula secondary to mandibular osteomyelitis].

Cutaneous fistulas and sinuses in the maxillofacial region secondary to osteomyelitis rarely appear in clinical practice. The most frequent cause of mandibular osteomyelitis is a dental infection, but it may also be hematogenic in origin. The diagnostic criteria for bacterial osteomyelitis are suppuration and osteolytic changes in the radiological study.
