Sphenoiditis is an inflammatory disease of the mucous membrane of the sphenoid sinus. As a rule, changes in the main sinus are combined with other rhinological pathology, while its isolated lesion accounts for only 1-2% of cases among all inflammatory pathologies of the paranasal sinuses. The anatomical and topographical features of the location of the sphenoid sinus, as well as the nonspecificity of symptoms, lead to late diagnosis of this disease. Among the complaints presented by patients, the most common is headache without clear localization (72%). In second place in terms of frequency of occurrence, visual disturbances are detected in the form of diplopia, progressive unilateral vision loss, and narrowing of the visual fields on the affected side. Visual symptoms account for 21% of patients with isolated sphenoiditis (IS). Rhinological manifestations of the disease include: mucus running down the back of the throat and nosebleeds. Thus, patients are under the supervision of doctors of related specialties for a long time: ophthalmologists, neurologists and other specialists.
