Application of navigation system during surgery for medication-related osteonecrosis of the jaw.

In recent years, surgical navigation systems have shown remarkable development and allow real-time navigation of the surgical field, including locations of anatomical structures and lesions. This ability allows procedures to be performed with a high degree of accuracy. In cases of medication-related osteonecrosis of the jaw (MRONJ), proper removal of sequestrum or necrotic bone is essential for postoperative healing. However, the boundary between necrotic and healthy bone is difficult to determine in preoperative images, and there are no clear standards regarding the extent of bone resection for MRONJ. Reported here are findings associated with surgical navigation for MRONJ to determine the extent of bone resection in real time. The technique is reliable for removal of necrotic bone and provides a better understanding of the extent of resection required.
