Diseases of the nose and paranasal sinuses are the leading pathology of ENT organs, the causes of which are the widespread prevalence of viral respiratory tract injuries, the unfavorable environmental situation in many regions, a decrease in immunity, smoking, and the influence of harmful occupational factors. In addition, congenital or acquired anatomical changes, such as deformation of the nasal septum, hypertrophy of the nasal turbinates, polyps, adenoids, etc., play an important role in the pathogenesis of this pathology. Simultaneous operations (from English "simultaneous" - simultaneously) are complex surgical operations aimed at simultaneous surgical correction of two or more diseases of various organs in one or more anatomical areas. Simultaneous surgeries are particularly important in cases where there is a pathogenetic link between two surgical diseases. In cases where the existing combined pathology is not simultaneously surgically corrected, the disease may worsen in the postoperative period. It should be noted that simultaneous surgical correction has economic efficiency compared to separate operations, which reduces bed-days by 2 or more times, reduces costs for examinations, pre-and postoperative treatment, and anesthetic drugs.
