Medication‐related osteonecrosis of the jaw: Case series and literature review

Key Clinical Message Medication‐related osteonecrosis of the Jaw (MRONJ) is a rare complication of the jaws following the administration of antiresorptive or antiangiogenic drugs. This condition poses a major challenge to its management. Its prevention and management need a multidisciplinary collaboration. We described three patients with MRONJ including their presentation, investigations, management protocols, and outcomes. A brief appraisal of the literature on MRONJ was also done. Abstract Medication‐related osteonecrosis of the jaw (MRONJ) is a rare complication of the jaws following the administration of antiresorptive or antiangiogenic drugs. This condition poses a major challenge to its management. We present an appraisal of the literature and three cases of MRONJ. An appraisal of 3 patients who presented to the oral and maxillofacial clinic with MRONJ was done. Relevant physical examination findings, radiological images, clinical photographs and follow‐up was documented. One patient had multiple myeloma while the other two had metastatic cancer. All had received zoledronic acid before developing MRONJ. One patient was surgically treated and successfully recovered while two were managed conservatively. Patients taking antiresorptive medications are at risk of developing MRONJ. Prevention and management of the condition calls for a multidisciplinary collaboration. Patients taking antiresorptive medications need good education on the risks associated with the medications and how to recognize early signs and symptoms.
