Emergency maxillofacial radiology. Foreign body localization: report of cases.

Successful emergency removal of foreign bodies of the maxillofacial complex depends on the surgeon's ability to perform exact location procedures. In hospitals and/or offices where advanced imaging technologies are not available, the attendant clinician has to use and rely on variations of conventional radiographic techniques in order to complement the diagnosis and locate the foreign body. Three cases are presented where unconventional radiographic techniques were used, leading to successful surgical removal of foreign bodies.
