In this study, we report a case of a patient with medication-related osteonecrosis of the jaw (MRONJ) with maxillary sinusitis. The patient was successfully evaluated using 99mTc-bone scintigraphy combined with panoramic radiography and computed tomography, enabling early diagnosis and surgical treatment. The inflammation was limited to the maxillary antrum at the bottom of the jawbone and mandibular bone; therefore, we performed sequestrectomy for the maxilla and mandibular bone. As a result, the patient is now at postoperative 1 year and 8 months and the course remains good. We adopted imaging techniques to positively determine the treatment strategy for this MRONJ case, and we will repeat this approach depending on clinical conditions to further examine outcomes in future.
