[Mandibular osteomyelitis after mandibular conduction anesthesia].

Several complications following a mandibular nerve block were reported in the literature. In some cases pterygomandibular abscess formation may be caused by mandibular needle injections. There is no report of odontogenic osteomyelitis of the ascending mandibular ramus in the literature. Here two patients with osteomyelitis of the ascending ramus following a mandibular nerve block injection are presented.
