Case report of two patients with silent sinus syndrome

Abstract

SMS is a rare pathology of the paranasal sinuses, accompanied by such symptoms as pain in the eye area, enophthalmos and hypophthalmos on the side of the localization of the process, facial asymmetry caused by a decrease in the volume of the maxillary sinus due to its atelectasis in the presence of chronic inflammation in it. The disease, as a rule, proceeds under the primary diagnosis of chronic rhinosinusitis. The main pathogenetic link of the disease is generally accepted as the block of the anastomosis and the emergence of the valve mechanism of ventilation of the maxillary sinus. However, the immediate cause of the onset of atelectasis remains a subject of discussion to this day. The only effective surgical treatment is to restore ventilation of the maxillary sinus by expanding the anastomosis and eliminating the cause of its block. With a pronounced asymmetry of the face due to the lowering of the orbit, the plastic of the lower wall of the orbit is performed. The article discusses modern ideas about the silent sinus syndrome, its etiology, pathogenesis, clinical course and treatment tactics for patients, presents two clinical observations of patients with silent sinus syndrome and describes the options for surgical treatment and its results.
