Methods of preoperative assessment of function of the auditory tube in patients with chronic tubotympanal purulent otitis media

Abstract

AbstractIntroduction. The purpose of the study was learning diagnostic tools of Eustachian tube pathology and define the highly specific prognostic test. The Eustachian tube is a specific structure that is difficult to visualize and manipulate due to its location and anatomical features. Maintaining adequate aeration and physiological pressure in the tympanic cavity is extremely important for middle ear function. The preoperative assessment of the auditory tube function is still important. A lot of studies demonstrate majority methods of evaluation tube function. However, there is no gold standard for diagnosing tubular dysfunction.Goal of reserch. The purpose of this review is to analyze methods for studying the function of the auditory tube as a preoperative preparation for hearing-enhancing operations, namely tympanoplasty.Materials and methods. We analyzed the database related to modern methods of evaluation Eustachian tube function and tympanoplasty outcomes.Results. Despite a large number of studies, the question of a priority and universal method for the preoperative assessment of the function of the Eustachian tube remains open. Each of the studies presented in this review has its own advantages and disadvantages associated with the complexity of the implementation or limitation of application. Endoscopic examination is the most informative for assessing the anatomical state of the auditory tube and nasopharynx. To assess the physiological function, a group of manometric tests, namely tubomanometry and the ETF-test, turned out to be more accurate, universal, and easily conducted.Conclusion. The work of the auditory tube is of great prognostic value for conducting auditory-improving operations and determining treatment tactics. Identification of the “gold standard” of diagnosis will help improve the quality and increase the effectiveness of surgical treatment, and therefore, further research in this area is necessary.
