Orbital Abscess

• Orbital cellulitis is usually a complication of paranasal sinus infection.
• Either the infection might possibly dissect under the periosteum and lead to subperiosteal abscess (SPA) or intraorbital abscess might possibly be formed secondary to a progressive and localized cellulitis.

• Without appropriate treatment orbital infection might possibly lead to serious complications, even death.
• Prompt treatment is mandatory to avoid visual loss or intracranial complications. Initially, IV antibiotics might possibly be administered, but if no improvement appears within 48h, surgical drainage of the orbit and the affected sinuses must be performed.
• In medial or medial-inferior SPA a transnasal approach is used, but in superior orbital abscess an external incision is required.
