Orbital subperiosteal abscess and blindness complicating a minimally displaced zygomatic complex fracture

A case of orbital subperiosteal abscess (SPA) complicating a minimally displaced zygomatic complex (ZMC) fracture is reported and the aetiology and management of this potentially life-threatening condition is discussed. The valuer of CT scanning in staging orbital infection and determining the site of the abscess and involved paranasal sinuses is emphasized. The correct interpretation of a lateral skull radiograph with the patient brow up may have lead to earlier diagnosis and treatment.
