Sphenoiditis is rare and is usually associated with a disease of the ethmoid labyrinth - its posterior cells.

Symptoms, course. Headache complaints. Most often it is localized in the crown of the head, in the depths of the head and neck, the orbit. With chronic lesions, pain is felt in the crown of the head, and with large sizes of the sinuses, it can spread to the back of the head. With rhinoscopy, the accumulation of discharge in the olfactory gap is determined. Often visible strips of pus flowing down the arch of the nasopharynx and the posterior pharyngeal wall. With unilateral sphenoiditis, unilateral lateral pharyngitis is observed. Sometimes patients complain of a rapid decrease in vision, which is associated with involvement of the optic nerves in the process of intersection. Chronic sphenoiditis can occur with mild symptoms. Of great importance in the diagnosis of sphenoiditis is an X-ray examination.

Treatment. Frequent lubrication of the mucous membrane of the nasal cavity by vasoconstrictors to ensure the outflow of discharge from the sinuses. In case of a prolonged disease, probing and washing of the sinus with antibiotic solutions is recommended. Surgery is sometimes indicated (for example, resection of the posterior end of the middle shell).

Prevention of sinusitis should be aimed at treating the underlying disease (flu, acute runny nose, measles, scarlet fever and other infectious diseases, tooth damage), eliminating predisposing factors (curvature of the nasal septum, atresia and synechia in the nasal cavity, etc.). An important role is played by the systematic hardening of the body.
