Chronic tonsillitis is one of the most common pathologies of the lymphoepithelial pharyngeal ring. The main pathogen in chronic tonsillitis and its complications is group a β-hemolytic Streptococcus A (BGSA). This pathogen is detected in 30–60% of patients. At the present stage, the role of latent viral infections (Epstein – Barr virus (EBV), cytomegalovirus (CMV)) in the formation of chronic tonsillitis in children has been proven. Treatment of frequently ill children with pathology of the pharyngeal lymphoid ring remains an urgent and widely discussed issue. Depending on the etiology and clinical form of chronic tonsillitis (simple, toxicallergic form (TAF I or II), the choice is between conservative methods and radical surgical treatment. Surgical treatment of chronic tonsillitis in children is recommended only if there are absolute indications. To standard methods of conservative treatment, such as sanation of lacunae of the tonsils with antiseptic solutions, the appointment of physiotherapy, funds for the correction of systemic and local immunity are actively used. In Pediatrics, the safe and optimal complex of effects of the herbal medicinal product Tonsilgon N is widely used. Based on the analysis of clinical observations of frequently ill children with chronic tonsillitis, the effectiveness of the herbal medicine Tonsilgon H (in monotherapy mode) was revealed. As a result, the expediency of using the drug Tonsilgon H in the treatment of compensated forms of chronic tonsillitis in frequently and long-term ill children was established. There was a significant decrease in the frequency of acute respiratory infections and, consequently, the risk of transition to a decompensated form of chronic tonsillitis.

Hearing loss is socially significant problem. About 30% of all cases are due to sensorineural hearing loss. Taking into consideration its polyethiologic nature treatment tactics should be complex. Drugs, that are able to reduce neuropathy development, should be an integral part of treatment. Most of neurotropic vitamins improve metabolic and enhance the regenerative processes in neuroepithelium. For this purpose vitamins B1, B6 and B12 are ordinary used, for many years they are included in the complex treatment of diseases of the peripheral nervous system. One of the combined medicinal vitamins is neuromultivitis.

The pathological inflammatory process in the Eustachian tube, as well as the catarrhal stage of acute otitis media, are the most common conditions in the practice of a pediatric otolaryngologist. The article presents literature data on acute pathology of the middle ear, epidemiology, etiology and standard conservative therapy. The fact of the influence of persistence of herpes virus infection on the development of hyperplastic processes in the lymphoid ring of the pharynx in children is described. It was noted that there are few data on the conduct of etiotropic and pathogenetic therapy in patients with acute middle ear pathology infected with pathogens of latent infections in the literature. The article presents a clinical case of successful treatment of the patient with acute otitis media and timely identified markers of an active infection process. Also the determination of clear indications and the timing of the specific conservative treatment of acute otitis media in children, based on an analysis of the etiological aspects of the development of this disease, the duration and somatic condition of the patient allowed to reduce the percentage of complications and relapses in the development of acute otitis media. When selecting adequate therapy for acute otitis media in children, it is necessary to consider the etiology of the disease in each individual patient. In the presence of acute lymphoproliferative syndrome in combination with middle ear inflammation, it is necessary to verify the causative factor with a laboratory examination (diagnosis by polymerase chain reaction and enzyme-linked immunosorbent assay with antibody detection) for herpes virus infection (Epstein-Barr virus, cytomegalavirus, herpes simplex virus 6 type), with further selection of specific therapy and observation of an otolaryngologist and infectious disease specialist.

Clinical and audiological investigation of 100 children with indications for cochlear implantation was made. Indirect signs of intrauterine infection were identified, as well as the presence of predisposing factors to the development of exudative otitis media. During the investigation frequency of exudative otitis media (up to 21%) in children with high grade sensoneural hearing loss was made. The severity of lymphoproliferative syndrome and it’s combination with herpesvirus infection markers (Cytomegalovirus, Epstein-Barr virus). It was found out, that in group of patients with combination of high grade sensoneural hearing loss and exudative otitis media lymphoproliferative syndrome in more, than 77% cases had herpesvirus ethiology and significantly exceed the same data in group of patients with isolated hearing loss.
