Diagnosis:

Blowout fracture

Discussion:

The floor of the orbit is the most common portion of the orbit to sustain fracture. A classic radiographic finding in blow-out fractures is the presence of a polypoid mass (the tear-drop) protruding from the floor of the orbit into the maxillary antrum The tear-drop represents the herniated orbital contents, periorbital fat and inferior rectus muscle.
