Surgical management of pathologic mandibular fractures

Background: The aim of this article was to present our experience in the management of pathologic mandibular fractures. Methods: We conducted a retrospective analysis of 14 patients with pathologic mandibular fractures associated with osteoradionecrosis, bisphosphonate-related osteonecrosis of the jaw, benign/malignant lesions, osteomyelitis, idiopathic, or iatrogenic etiology. Data collected included age, sex, etiology, site, treatment, and outcome. Results: Five patients had iatrogenic fractures, 3 patients had osteomyelitis, 2 had benign cystic lesion, and the remaining 4 had primary squamous cell carcinoma, histiocytosis, multiple myeloma, and bisphosphonate-related osteonecrosis of the jaw, respectively. Eleven fractures of 14 were treated using a 2.4-mm mandibular plate. Conclusions: Pathologic mandibular fractures may be challenging to treat because of their different etiology and peculiar local and general conditions, often requiring a more rigid fixation. In patients with poor medical conditions, simpler and more limited options may be preferred.
