Abstract

Osteomyelitis is classified into three groups according to its origin: osteomyelitis that originates from the blood supply, osteomyelitis related to bone disease or vascular disease, and osteomyelitis related to a local infection of dental or non-dental origin. The present case involved osteomyelitis related to a local infection of dental origin and was located in the rear area of the lingula of the mandible. We decided to use sagittal split ramus osteotomy to access the osteomyelitis area. Under general anesthesia, we successfully performed surgical sequestrectomy and curettage via sagittal split ramus osteotomy.
