Inflammatory diseases of the ear are among the most acute problems in modern otorhinolaryngology. Patients with various forms of otitis media account for 34% of all patients served by outpatient clinics. According to the Medical Statistics Bureau of the Moscow Health Department, in 2003-2010 the proportion of patients with otitis media in the total number of patients with ear diseases visiting ENT specialists at municipal polyclinics reached an average of 50%.

Treatment recommendations are proposed.

According to statistics for the past 25 years, the incidence of acute external otitis media has not decreased. This is a very common disease occurring in all age groups and accounting for over a quarter of all otiatric cases (1, 3, 6, 8, 9). According to certain data, the incidence of otitis externa is from 12.9 to 21% in children with diseases of the ear (1, 3, 10). There has been a significant increase in patients with external otitis recently conditioned by a wide use of headphones, popularity of different water entertainments (swimming pool, water park) and occupational hazards (1, 4, 6, 8). Acute otitis media is one of the most common diseases in children (1, 10). It should be noted that complications of acute otitis media (persistent perforations, adhesions in the tympanic cavity, auditory nerve damage) are a major cause of hearing loss (5).

Acute respiratory viral infections (ARVI) are the most frequently occurring. Physicians of all specialities have to deal with ARVI in outpatient practice. In the present-day environment of the population migration, people concentration in metropolitan areas and active communication, viruses spread very easily and lead to unhealthy conditions. [7]. The high prevalence is explained by the easy transmission of the source of infection by airborne droplets. Influenza and ARVI account for 90-95% of all infectious diseases. The share of influenza in the overall Russian epidemics ranges from 10 to 60% [3]. In addition to epidemic outbreaks in the last century, the world recorded 4 pandemics [23].

ENT specialists are increasingly concerned about high incidence of the mucous membrane disorders in the upper respiratory tract. To paraphrase a well-known expression, it can be argued that there are no patients with completely healthy noses and sips, but there are patients who have not yet got tired of constant tickling in the throat, mucus discharge, nasal congestion and other symptoms.

Acute otitis media (AOM) is one of the most common diseases in children as well as in adults worldwide which makes a relevant social and economic impact. AOM treatment should primarily take into account the stage of the disease; it should be combined and focused on remedying the inflammatory process as well as alleviating the patient's condition.

There is a marked aggravation of allergies and polysensitization; immunological disorders are accompanied by comorbid infectious complications. Allergic rhinitis is a global healthcare problem. The focus of the international medical community is explained by a range of medical and social reasons. Treatment of allergic rhinitis requires a comprehensive approach taking into account the pathogenesis of the disease.

The article is devoted to the diagnosis and treatment of patients with cochleovestibular disorders of various origin. The article tells about diagnosis, surgical techniques and their outcomes in patients with Meniere's disease, perilymphatic fistulas of the labyrinth, including patients after stapedoplasty and at Minor's disease, with fistulas of the labyrinth in chronic suppurative otitis media.

Otitis media with effusion (EDF) which continues to be a relevant issue in pediatrics is the main cause of hearing loss in children aged 2 to 7 years [1, 2]. Depending on the stage of the process, both conservative and surgical methods of EDF treatment are used today.

ARVI is a short-term infection of the upper respiratory tract (including middle ear cavity and paranasal sinuses) which is caused by various respiratory viruses. According to the WHO [1], ARVI affects every third person every year. During epidemic outbreaks, 27.3 to 41.2 million cases are registered in Russia, of which 2 million are located in Moscow [2]. Despite a wide range of antiviral and symptomatic medications, the problem of treatment and prevention of ARVI is far from being finally solved. That's why medicines that strengthen the immunity of a macroorganism are becoming increasingly popular.

Allergic rhinitis (AR) is a chronic allergic disease caused by IgE-dependent allergic inflammation. It occurs when allergens affect the nasal mucosa and is clinically manifested by rhinorrhea, nasal congestion, sneezing, and sometimes anosmia [1].

Till now acute respiratory infection (ARI) remains one of the most pressing problems in the healthcare practice due to the extremely high level of morbidity, especially pronounced during seasonal epidemics. According to the global data,every adult annually suffers from a minimum 23 episodes of ARVI, and children - from 6-8 [13]. High incidence of acute respiratory infections is associated with a heavy economic burden, primarily due to indirect costs as a result of loss of labour capacity.
