Non-drug methods of influencing the pharyngeal tonsil and their clinical effectiveness in the complex therapy of chronic adenoiditis in children

Background. The importance of finding additional treatments for chronic adenoiditis is determined by its high prevalence. Aim. To evaluate the clinical effectiveness of low-frequency ultrasonic cavitation in combination with photochromotherapy in the complex therapy of chronic adenoiditis in children. Material and methods. Three groups were formed by randomization by the envelope method. Patients of the control group (the first group, 32 children) were not exposed to physical methods. One study group (the second group, 27 children) received low-frequency ultrasonic cavitation with photochromotherapy on the lymphoid tissue of the pharyngeal tonsil; another study group (third group, 25 children) low-frequency ultrasonic cavitation. The course of treatment was 7 days. Comparative evaluation of indicators was carried out before the start of therapy and on the 7th day. The dimensions of the pharyngeal tonsil were visualized, and the pathological discharge on the surface of the adenoid vegetations was assessed. For nominal data, absolute and relative frequency (%) were calculated, group comparison was performed using Pearson's 2 test. Results. After treatment in the second group, there was a decrease in the amount of purulent discharge on the surface of the pharyngeal tonsil by 35%, mucous by 20% (p=0.000), the number of children with grade 3 adenoid hypertrophy decreased by 55% compared with the period before the use of physical methods impact (p=0.000). In the third group, the same data were obtained a decrease by 35 and 20%, respectively, in the amount of purulent and mucous discharge (p=0.000), the proportion of children with grade 3 adenoid hypertrophy decreased by 44% (p=0.000). Low-frequency ultrasonic cavitation increases the effectiveness of conservative treatment by 2.08 times (confidence interval 1.02; 4.22), and in combination with photochromotherapy 2.37 times (confidence interval 1.21; 4.67) compared with the control group. Conclusion. Low-frequency ultrasonic cavitation with photochromotherapy is effective in the complex therapy of chronic adenoiditis in children.
