The Role of Computed Tomography in the Diagnosis of Subperiosteal Abscess of the Orbit

Periorbital cellulitis is a frequent complication of sinusitis in children. Subperiosteal abscess (SPA), however, is an uncommon sequela and may lead to serious complications if not promptly and adequately treated. A series of 13 consecutive patients who underwent orbital computed tomographic (CT) scans from January 1, 1986, to June 30, 1989, to investigate the possibility of SPA were reviewed. As demonstrated in this series, the diagnosis of subperiosteal abscess remains a clinical one that may be supported, but not determined, by an orbital CT scan. Cautious interpretation of these studies is advocated. Aggressive surgical therapy in appropriate clinical situations will lead to more rapid resolution of the disease process and fewer complications.
