ENT diseases are one of the most common reasons for visiting a doctor, especially in paediatric practice. The issue of interdisciplinary interactions between otorhinolaryngologists and paediatricians, their consistency in choosing therapy is extremely important. About 90% of morbidity rates relate to acute infectious respiratory viral etiology, which is characterized by high transmissibility and variability of manifestations. Particular attention should be paid to children attending preschool facilities, as they can catch acute respiratory viral infections up to 8 times a year, and 10-15% of them up to 12 times a year, which is 2 times more often than children who do not attend school, kindergarten, or any other educational facilities. The premature and unjustified prescription of antibacterial drugs, both local and systemic, remains a serious problem in the choice of therapy, which leads to increased number of antibiotic-resistant bacterial strains. Therefore, the issue of prevention and rational therapy, improvement of its effectiveness by the use of safe drugs appears relevant. The article points out that the irrigation-elimination therapy has been and remains the foundation of the prevention and treatment of diseases of the nasal cavity, paranasal sinuses and nasopharynx. The effectiveness and safety of this therapy has been studied and proven in the studies, and the inclusion of irrigation-elimination therapy in the international consensus documents such as EPOS 2012 and ARIA 2008 allows it to be widely used for the treatment of various ENT pathologies. It should be noted that availability of irrigation salt solutions with silver ions have significantly added to the possibilities of keeping the use of more aggressive drugs to a minimum, especially if the course of the disease is not complicated. Aquanasal drug containing natural Altai mineral water rich in silver ions is one of the commonly used drugs of a similar character with a wide range of indications, which has anti-inflammatory, anti-edematous, antimicrobial, antifungal and antiviral effects.
