In rare cases, antiresoprtive medications for osteoporosis cause osteonecrosis. Necrotic bone lesions localized at the jaw after the use of antiresorptive medications is named medicationrelated osteonecrosis of the jaw (MRONJ). Although some cases with MRONJ affect the paranasal sinus, inferior turbinate necrosis have not been reported in South Korea yet. Here, we report a case of inferior turbinate osteonecrosis that developed after denosumab had been used.
