Use of Vancomycin-Impregnated Calcium Sulfate in the Treatment of Osteomyelitis of the Jaw.

PURPOSE: The aim of this study was to describe the effect of vancomycin-impregnated calcium sulfate in the treatment of osteomyelitis of the jaw. MATERIALS AND METHODS: Twelve patients who were diagnosed with osteomyelitis of the jaw underwent treatment with vancomycin-impregnated calcium sulfate since July 2014 at the Department of Oral and Maxillofacial Surgery, School of Stomatology, China Medical University (Shenyang, China). All patients underwent debridement of nonviable bone and implantation of vancomycin-impregnated calcium sulfate. The wounds were covered with an acellular dermal matrix and sutured. RESULTS: Ten patients had satisfactory wound healing. However, 2 cases of maxillary central osteomyelitis had delayed wound healing. The wounds healed after the surgical site was resutured under local anesthesia. At 3 months, the panoramic radiograph showed that most implants had been reabsorbed and replaced by new bone formation. All patients in this study had no recurrence of infection at 6 to 18 months (mean, 10.8 months) of follow-up. CONCLUSIONS: The use of vancomycin-impregnated calcium sulfate in the surgical debridement site for chronic osteomyelitis of the jaw has shown encouraging results. In addition, calcium sulfate can promote the formation of new bone to a certain extent.

Clinical Characteristics and Treatment of Osteopetrosis Complicated by Osteomyelitis of the Mandible.

Osteopetrosis represents a heterogeneous group of rare, hereditary bone disorders with variable clinical features, and an increase in bone density. Osteomyelitis of the jaws is a significant complication of osteopetrosis. In this article, a reported patient with osteopetrosis complicated by osteomyelitis of the mandible was examined. The patient was treated with intravenous antibiotic therapy, debridement of necrotic bone and hyperbaric oxygen therapy; in addition, the authors attempted to implant the calcium sulfate and vancomycin to reconstruct the bone defect. The patient demonstrated satisfactory healing, and no recurrence of osteomyelitis was observed during the 6-month follow-up period. The treatment of osteopetrosis complicated by osteomyelitis of the mandible is difficult. The treatment of osteopetrosis complicated by osteomyelitis is controversial. The authors recommend the following sequential treatment of osteopetrosis complicated by osteomyelitis of the mandible: systemic antibiotic therapy and hyperbaric oxygen therapy before and after surgery; debridement of the necrotic bone; sufficient periosteal coverage and adequate soft tissue to cover the wound; implantation with calcium sulfate and vancomycin to reconstruct the bone defect as much as possible, which may be helpful in treating the disease.
