[The medical assistance seeking behaviour of the patients presenting with suppurative chronic otitis media and their treatment in Moscow].

The objective of the present study was the analysis of the medical assistance seeking behaviour of the patients presenting with suppurative chronic otitis media (CSOM) and their treatment in Moscow during the period from 2009 till 2016. The incidence of suppurative chronic otitis media in the city of Moscow in 2016 was estimated to be 0.14 per 1000 population, its prevalence 1.

[The application of contrast-enhanced X-ray salpingography for the evaluation of the effectiveness of catheterization of the acoustic tube with the use of the Eustachian catheters].

The objective of the present study was to evaluate the effectiveness of the administration of a medication into the middle ear structures during catheterization of the acoustic tube (AT) in the course of the contrast-enhanced X-ray salpingographic investigation. The study included 18 patients (18 ears) presenting with chronic otitis media and the perforated tympanic membrane without the disturbances of the ventilation function of the auditory tube. All the patients were allocated to two groups depending on the type of the Eustachian catheters being used.

[The fistula of the round window of the cochlea].

A case of this pathology is reported with the special emphasis placed on the approaches to the diagnostics and surgical management of this condition.

[Multiple pneumocele associated with temporal bone hyperpneumatization].

The authors consider in brief epidemiology, diagnostics, and variants of the surgical treatment of the rare clinical condition pneumocele and pneumoencephalocele of the temporal bone.

[The prevalence of tympanosclerosis and the effectiveness of its surgical treatment].

The objective of the present study was to characterize the epidemiological variants of tympanosclerosis and the effectiveness of the surgical treatment of the patients presenting with this condition. We have undertaken the analysis of the results of 1965 surgical interventions on the patients suffering from different forms of chronic otitis media (COM) performed during the period from 2009 till 2014 with a view to determining the frequency of tympanosclerosis (TSC). In 542 cases, it proved possible to evaluate the intraoperative findings, stages and methods of reconstructive surgery, the anatomical and functional outcomes and effectiveness of the intervention.
