Rhinosinusitis is a clinical condition frequently encountered by otorhinolaryngology, pediatrics and general practitioners and continues to be an important public health problem. Delayed or inadequately treated cases of rhinosinusitis are vulnerable to orbital and intracranial complications. While orbital complications affect 3% of rhinosinusitis patients, an average of 60% of orbital infections are caused by rhinosinusitis. While orbital complications are mostly caused by ethmoid sinusitis, frontal sinusitis is the source of intracranial complications . Early diagnosis and initiation of effective antibiotic treatment are of key importance in orbital complications due to rhinosinusitis. As the treatment of orbital complications is delayed, the spread of infection and increase in morbidity and mortality are inevitable. Although there has been a significant decrease in the number of orbital complications with the use of antibiotics, such complications can still have serious consequences when they occur. Some clinicians may graduate without ever encountering complications from rhinosinusitis during their training. In this study, we aimed to draw attention to rhinosinusitis-induced orbital complications in clinical practice, to describe these clinical situations in detail and to explain the treatment options.
