RESUMO
Each person experienced an unpleasant sensation of congestion of the ear during a flight or in rhinorrhea, which is caused by dysfunction of the Eustachian tube (ET). People with persistent ET dysfunction live with this sensation for months and years. Persistent ET dysfunction in children reaches 40%, in adults it is up to 5%. Most of the pathological conditions of the middle ear, leading to socially significant hearing loss, and the main reasons for failures in hearing-improving operations are associated with persistent ET dysfunction. The effectiveness of various methods of treating this pathology, despite their large quantity, still remains doubtful due to the lack of clear criteria and golden standard for diagnosis, indications for specific methods and long-term results of treatment. According to the aim of the study a diagnostic and treatment algorithm was developed for persistent ET dysfunction in adults and children. We researched this problem for more than 10 years, and the effectiveness of the proposed diagnostic and therapeutic measures has been statistically proven, both by a large sample of patients and by a long period of observation. Researchers of L. I. Sverzhevsky Research Institute of Otorhinolaryngology have developed a diagnostic algorithm for persistent ET dysfunction, optimized the treatment of persistent dysfunction and recurrent concomitant secretory otitis media, and also determined the indications and methods for conducting ET balloon dilatation in adults and children with persistent ET dysfunction. We improved the functionality results of hearing-improving operations (tympanoplasty) in patients with persistent ET dysfunction. All of the above allowed us to reduce the treatment time for this group of patients by up to 50%, to achieve high clinical efficacy in up to 100%, and to obtain a lasting functionality in hearing-improving operations in 93% of cases.
