Orbital Complications of Sinusitis
Sinusitis can lead to local and systemic complications. Anatomically, most local complications are linked directly to the paranasal sinuses and other structures of the head, neck, and chest. The structures involved most often are those of the orbit, cranium, chest, and nose. Sinusitis can lead to the development of local complications, such as orbital cellulitis, subperiosteal abscess, and orbital abscess, intracranial disorders (brain abscess [BA], subdural empyema [SE] and meningitis, facial osteomyelitis, and thrombosis of the cavernous sinus and cortical vein (1,2). The precise rates of these complications are not known, but they occur in about 5% of patients hospitalized for sinusitis.
This page describes the microbiology, and antimicrobial management of orbital and intracranial complications of sinusitis. It is imperative to consider also the use of surgical treatment in these conditions. However, this review is not describing these issues.
