Neurological Complications of Acute and Chronic Sinusitis

Curr Neurol Neurosci Rep. 2018 Feb 5;18(2):5. doi: 10.1007/s11910-018-0816-8.

Abstract

Purpose of review: Acute and chronic sinusitis can give rise to a wide array of intracranial and orbital complications. These complications include brain abscess, subdural empyema, epidural abscess, meningitis, venous sinus thrombosis, frontal bone osteomyelitis, and orbital cellulitis and abscess. Despite numerous medical advances, these complications carry a risk of mortality and significant morbidity.

Recent findings: Recent studies have shown improvement in both the mortality and the morbidity associated with the neurologic complications of acute and chronic sinusitis. However, there are still a large portion of patients with long-term sequelae, and the literature reports a morbidity rate of approximately 30%. The most common post-treatment morbidities include permanent changes in vision, seizures, and hemiparesis. Although the overall incidence of neurologic complications from a sinogenic source are rare, the potential long-term complications can be devastating making prompt diagnosis and treatment vital to improving outcomes.

Keywords: Intracranial complications; Neurologic complications; Orbital complications; Sinusitis.
