To determine the structure and nature of headache in pediatric patients, as well as its relationship with chronic rhinosinusitis, to develop an effective rehabilitation course for pediatric patients with headache at the sanatorium-resort stage. The study included 100 patients aged 8 to 17 years who received a course of sanatorium treatment. Patients were divided into groups: with primary headache and with secondary headache in chronic rhinosinusitis. The results of a comprehensive otorhinolaryngological and neurological study made it possible to determine the mechanism of development, structure, and nature of the predominant types of headache in children and to develop a course of rehabilitation treatment. An analysis of the effectiveness of the rehabilitation course showed that it was possible to achieve a positive result in 88% of children with primary and secondary headache. The necessity of interdisciplinary participation of otorhinolaryngologists and neurologists in the examination and treatment of patients complaining of headache at the sanatorium-resort stage is substantiated. The effectiveness of the proposed rehabilitation course of headache treatment of various origins in children has been proven, the analysis of long-term results allows us to recommend it during staged therapy.
