Sinusitis complications

The paranasal sinuses are in close anatomical contact with the nasal and oral cavities, the orbit, the skull base, the brain, and important neurovascular structures, so complications of sinusitis can have serious and life-threatening consequences. Roughly, complications are divided into extracranial and intracranial. Of the extracranial complications, orbital complications are the most common. In addition to clinical examination and immediate referral to hospital, diagnostic imaging methods, particularly CT, are important in the diagnosis of complications. The treatment of complications of sinusitis is mainly multidisciplinary and may involve pediatricians, family physicians, emergency physicians, otorhinolaryngologists, neurologists, neurosurgeons, ophthalmologists, neuroradiologists, and infectious disease specialists. The cornerstone of treatment is early targeted antimicrobial therapy and surgery for abscess, visual impairment, or involvement of critical neurovascular structures. This paper reviews sinusitis complications and provides study material for physicians who manage this disease.
