BACKGROUND: Bisphosphonate-related osteonecrosis of the jaws (BRONJ) is the most serious complication of bisphosphonates therapy. Despite that several treatment modalities have been described, aggressive surgical treatment approach with wide bone resection and vascularized microsurgical reconstruction are controversial. The aim of this study was to evaluate the clinical outcome of 8 new cases of BRONJ treated with radical resection and mandibular reconstruction with fibula free flap, to enforce the evidence about the reliability of this treatment option.
METHODS: Retrospective data of 8 patients with BRONJ who underwent segmental mandibulectomy and reconstruction with osteocutaneous fibula free flap from January 2004 to January 2008 were collected, including 6 patients with stage 3 BRONJ and 2 patients with recalcitrant stage 2 BRONJ.
RESULTS: All patients were white, with a mean age of 64.7 years (range, 53-77 y), and 62.5% were women. All bisphosphonates were administered intravenously, and all patients had mandibular localization. The mean period of follow-up was 28.9 months. No flap loss or minor complications and no BRONJ recurrence were observed. All patients were able to ambulate pain-free.
CONCLUSIONS: Despite initial concerns regarding reliability of the mandibular free-flap reconstruction after BRONJ, this method seems to be a safe and feasible option in cancer patients with reasonable life expectancy, with complete BRONJ resolution and life quality improvement. Our findings confirm data previously published by other authors, without complication and with a much longer median follow-up time.
