Odontogenic infection leading to orbital cellulitis as a complication of fracture of the zygomatic bone.

We describe a 51-year-old man in whom chronic maxillary sinusitis developing from a deep periodontal pocket, at 26, gave rise to cellulitis of the left orbit. The immediate cause was a fracture of the left zygomatic bone with some displacement of the infraorbital margin and the orbital floor. Treatment consisted of drainage and antibiotic medication. The zygomatic bone fracture was not reduced. Eye movements returned to normal and visual acuity was not permanently affected.
