Balloon dilation for eustachian tube dysfunction: systematic review

2016

Background: Eustachian tube dysfunction is a disorder for which there are limited medical and surgical treatments. Recently, eustachian tube balloon dilation has been proposed as a potential solution.Method: A systematic literature review was performed. Abstracts were selected for relevance, and pooled data analysis and qualitative analysis was conducted.Results: Nine prospective studies, describing 713 eustachian tube balloon dilations in 474 patients (aged 18-86 years), were identified. Follow-up duration ranged from 1.5 to 18 months. Ability to perform a Valsalva manoeuvre improved from 20 to 177 out of 245 ears following eustachian tube balloon dilation and, where data were reported in terms of patient numbers, from 15 to 189 out of 210 patients. Tympanograms were classified as type A in 7 out of 141 ears pre-operatively and in 86 out of 141 ears post-operatively.Conclusion: Prospective case series can confirm the safety of eustachian tube balloon dilation. As a potential solution for chronic eustachian tube dysfunction, further investigations are warranted to establish a higher level of evidence of efficacy.

“…Possible hypotheses previously proposed by McCoul and Anand include: submucosal microhaemorrhages, resulting in fibrosis that expands the cross-sectional diameter as the tissues heal; fibrocartilaginous cartilage of the eustachian tube retaining a 'memory' of dilatation more than hyaline cartilage would; improvement of epithelial ventilation through a transient reduction in mucosal oedema, permitting the recovery of mucociliary flow; and the initiation of a local signalling pathway within the mucosa that modulates the function of cartilage and muscle. 3 Despite an increasing number of technological advances, access to the eustachian tube remains challenging. Furthermore, a number of key anatomical structures lie close to the eustachian tube, which, if damaged, could result in serious morbidity or mortality.…”

Objective: To investigate the evidence for balloon dilatation of the eustachian tube using a transtympanic approach.Methods: A systematic search of several databases was conducted (using the search terms 'dilation' or 'dilatation', and 'balloon' and 'eustachian tube'). Only studies that used a transtympanic approach for the procedure were included. These studies were then assessed for risk of bias.Results: Three studies were included. Each of these studies was a limited case series, with two performed on human subjects and one on human cadavers. Results of safety and efficacy are conflicting. There is a high risk of bias overall.Conclusion: At present, there is a very narrow evidence base for transtympanic balloon dilatation of the eustachian tube. There are a number of advantages and disadvantages of the technique. Previously identified and theoretical safety concerns will need to be addressed thoroughly in future studies prior to wider clinical use.

“…Beside otoscopy and tympanometry, tubomanometry by Estève is the currently routinely used diagnostic tool before surgical intervention. Tube scores including swallowing, Valsalva manoeuvre, otomicroscopy and the results of tubomanometry [16,17] as well as questionnaires like the ETDQ-7 [18] were developed to assess Eustachian tube dysfunction value before and after treatment.…”

For years, several surgical and non-surgical therapeutic strategies in Eustachian tube dysfunction have been described. The Endonasal dilatation of the Eustachian tube (EET) utilising a balloon catheter is a feasible option in patients with symptoms of chronic obstructive Eustachian tube dysfunction. However, long-term results in a large series are missing. In a prospective case series, 217 patients (342 cases) with symptoms of chronic Eustachian tube dysfunction underwent uni- or bilateral EET at the ENT Department of the University of Hamburg, Germany, between September 2010 and April 2013. A tube score consisting of the type of tympanogram and the R value of the tubomanometry was used to evaluate pre- and postoperative tube function. All patients underwent follow-up with a post-operative interval of 3-12 months. The mean value of the pre-treatment tube score was 2.23 ± 1.147 and significantly improved to 2.68 ± 1.011 1 year after EET. There was a significant increase in the tube score during follow-up. The co-variables time period, tympanoplasty and pressure range showed a significant impact on the tube score. EET is a minimally invasive and effective treatment of chronic obstructive tube dysfunction. It is a safe procedure without causing significant complications. Nevertheless, long-term results of larger, placebo-controlled multicentre studies are needed to confirm its effectiveness.
