Bisphosphonates are used effectively for many medical conditions, such as multiple myeloma, Paget's disease, osteoporosis, etc. However, recent case series and retrospective studies have established a relationship between necrotic bone lesions localized to the jaw and the use of chronic bisphosphonate therapy. This condition has been named bisphosphonate related osteonecrosis of the jaw (BRONJ). Although some cases with BRONJ affect the paranasal sinus, they have been rarely reported in otorhinolaryngology. Hence, we report a case of BRONJ with sinus involvement and a review of the relevant literature.
