title: Fractures of the medial infraorbital rim.
abstract: Fractures of the medial infraorbital rim may occur independently or in conjunction with fractures of the nose and zygoma. Infraorbital fractures are frequently associated with anesthesia in the distribution area of infraorbital nerve and can produce palpable "step-off" deformities. Because roentgenographic and clinical indications of these fractures are often subtle, such injuries may go unrecognized in the presence of more obvious nasal fractures or may be misdiagnosed as "tripod" fractures. A proper recognition of these fractures is necessary for correct diagnosis and treatment. Three cases are presented and seven cases are summarized.
