New visual assessment of balloon dilation in Eustachian tube dysfunction

Abstract

Background:

Eustachian tube dysfunction (ETD) is a common problem, which can lead to hearing loss, aural fullness, retraction of the tympanic membrane, chronic otitis media and cholesteatoma. A well-established treatment option for ETD is the balloon dilation of the Eustachian tube (BET) to improve the ventilation of the middle ear by dilatating the diameter of the tube. The balloon dilation has been proven to be a valid, successful and low-risk therapy option. Up to now there exists no established pre- and perioperative visual surveillance to detect possible changes of the tympanic membrane during and after BET.

Methods:

In this prospective study the Clearscope Adaptor, a new diagnostic mobile phone tool, is used for ear video endoscopy to monitor the tympanic membrane movement and possible changes of retractions or adhesive processes during the performance of BET. Additionally a correlation to known middle ear pressure changes during the different steps of the procedure should be evaluated.

Results:

Up to now 6 patients could be examined during BET by using the Clearscope Adaptor in connection with a 30 ° endoscope and a suitable IPhone. The device was easy to use and provided valid video endoscopy of the eardrum. A correlation between the procedural steps and tympanic membrane movements could be observed.

Conclusions:

Visual assessment of movements of the eardrum as well as possible changes of adhesive process or retraction pockets are easily detectable by video endoscopy while performing BET.
