![]() It is a retrospective observational study and this study was done between May2018 to June 2019 at IMS and SUM Hospital, Siksha 'O' Anusandhan University, Bhubaneswar, Odisha, India. The aim of this study is to assess the indications, surgical technique, complications and effectiveness of the endoscopy guided transnasal balloon dilation of the eustachian tube. Currently eustachian tube balloon dilation is a new surgical technique which should be verified for its efficacy. The medical treatments of ET dysfunction are antihistamines, nasal decongestants and oral or nasal steroids.If conservative treatment for ET dysfunction fails, eustachiantuboplasty may be done with help of microdebrider or laser to remove hypertrophic mucosa and cartilage on the nasopharyngeal opening of the eustachian tube. The clinical presentations of the Eustachian tube dysfunctions are fullness of the ear, decreased hearing, otalgia, tinnitus and vertigo. ET dysfunction is usually seen in at least 1% of the adult population ( 3). Progressive development of flexible fiberoptic endoscopy has made hope for the first time to perform an atraumatic endoscopy of the ET ( 1).The anatomical and physiological description of the eustachian tube was first done by Italian physician BartolomeusEustachius in 1562, which dramatically changed the concept of this structure and etiopathology of middle ear diseases ( 2).Įustachian tube dysfunction is a common clinical entityencounteredbyotolaryngologists. Further development of ET function tests is required to facilitate the accurate diagnosis of patients and allow outcome reporting for new interventions.The evolution of rigid endoscope for endoscopic sinus surgery along with inflatable balloons for sinus surgery opened up new possibilities for treatment of eustachian tube (ET) dysfunction. Published accuracy data are limited and of differing quality due to the variability incomparative tests, and the spectrum of otological disorders associated with ET dysfunction.Ĭurrently, no single test could be considered a 'gold standard' for the diagnosis of ET dysfunction, but there is some evidence that diagnostic accuracy can be improved by combining the results of different objective tests and patient-reported outcome measures. While many tests of ET function have been developed, with some in routine clinical use, all have significant limitations. Significant variation in demographic characteristics, disease presentation and severity, and technological approaches only permitted narrative systematic review. ![]() Tests in included studies were required to measure a physiological function of the ET, or play a role in the diagnosis of poor ET function. MEDLINE, EMBASE, Biosis and the Cochrane library were searched and reference lists reviewed for relevant articles. This review aims to review the literature to identify currently available tests of ET function and, where possible, report on their accuracy. Despite this, there are no specific tests of ET function in widespread clinical use and no identified 'gold standard' with which to diagnose the disease. Eustachian tube (ET) dysfunction is a common but poorly understood cause of patient symptoms, and an important aetiological factor in the development of middle ear pathology.
