Abstract
PURPOSE: To document outcomes of management of juvenile mandibular chronic osteomyelitis (JMCO) using a standardized treatment protocol including open biopsy, decortication, microbial culture, and long-term antibiotic therapy. MATERIALS AND METHODS: This was a retrospective case study of pediatric patients with JMCO treated at Massachusetts General Hospital for Children from 1996 through 2014. Inclusion criteria included age younger than 18 years, diagnosis of JMCO, management by the protocol, adequate clinical and radiographic data in the record, and follow-up of at least 1 year after initial treatment. Inpatient and outpatient records were reviewed for demographics, clinical and radiographic findings, and histologic and laboratory evaluations. The predictor variable was the standardized treatment protocol and the primary outcome variables were disease status at end of treatment and complications of treatment. RESULTS: Twenty patients (mean age at onset, 10.7 yr; range, 3 to 14 yr) were treated, 12 (11 girls) of whom met the inclusion criteria. Management of all patients consisted of biopsy (extraoral when feasible, n = 9; intraoral, n = 3), decortication, cultures, and long-term antibiotic therapy. Nonsteroidal anti-inflammatory drugs (NSAIDs) were administered only as needed for pain control. There was complete resolution of osteomyelitis with no recurrence in 7 of 12 patients (mean follow-up, 4.3 yr; range, 1 to 11 yr). Five patients had partial responses, with decreased frequency and severity of disease recurrence. These were well controlled with short courses of antibiotics (4 to 12 weeks) with NSAIDs only as needed for pain control (mean follow-up, 1.4 yr; range, 1 to 3 yr). There were no major complications related to antibiotic therapy. Minor complications included rash (n = 2), nausea and vomiting (n = 1), and vaginal candidiasis (n = 1). CONCLUSION: The results of this study indicate that 58.3% of patients were cured and had no recurrent symptoms (mean follow-up, 4.3 yr). The remaining patients continue on intermittent treatment with antibiotics for recurrent episodes of swelling and pain. Favorable responses to antibiotic therapy support the hypothesis that JMCO is an infectious disease and that negative cultures might represent a failure of standard culture techniques to isolate the responsible organisms.
