title: Orbital cellulitis of dental origin: differential diagnosis and the use of computed tomography as a diagnostic aid.
abstract: This report illustrates the spread of odontogenic infection to the orbit and the usefulness of the CT scan for the differential diagnosis of periorbital vs orbital cellulitis and abscess. It shows the necessity for close follow-up of patients with odontogenic infection so that life-endangering complications may be treated promptly. Finally, this patient illustrates the fact that, in some cases, a dental infection may be so virulent that drainage through the tooth and antibiotics do not provide control. Tooth removal and prompt incision and drainage are required for adequate treatment.
