INTRODUCTION: Surgical treatment of bisphosphonate-related osteonecrosis of the jaws (BRONJ) combines excision of adequate damaged bone and watertight coverage by appropriate vascularized tissue. Local tissues are preferred when possible. This study compares local mucoperiosteal flaps with mylohyoid flaps with special emphasis on their influence on wound healing. MATERIAL AND METHODS: A total of 195 patients with BRONJ in the mandible were included in this prospective study. The control group (n = 169) were treated with a mucoperiosteal flap, whereas patients of the study group (n = 26) received a mylohyoid flap. RESULTS: Recurrence of BRONJ was significantly reduced (p = 0.023) as was extent of necrosis (p = 0.001) in patients with mylohyoid flaps. DISCUSSION: This study demonstrates the importance of a sufficient mucosal coverage in surgical treatment of BRONJ. The mylohyoid flap provides an additional tissue coverage, which seems to account for the significantly reduced rate of disease recurrence. CONCLUSION: The vascularized mylohyoid flap is an important tool in the complex and challenging surgical care of BRONJ.
