Evaluation of middle ear pressure changes during Eustachian tuboplasty under pathophysiological conditions
Objective Balloon Eustachian tuboplasty (BET) is a fairly novel and successful method for obstructive Eustachian tube dysfunction with a low complication rate. Due to the middle ear pressure changes during this procedure some rare but serious complications such as hearing loss can occur. Because of the risk of hearing loss and the lack of data about management techniques of BET further research is needed to understand and avoid complications. Methods Using cadaver heads a micro-optical pressure sensor middle ear pressure changes during BET under pathological conditions (fast withdrawal of balloon catheter, withdrawal with middle ear fluid and withdrawal with non-deflated balloon catheter) were measured.
Results Incorrect withdrawal of the balloon catheter causes high increase of middle ear pressure and can be associated with round window disruptions.
Conclusions The correct techniques of BET, specifically the condition of balloon catheter during withdrawal, is a prerequisite for avoiding barotrauma. This knowledge can avoid complication during BET and make it safer as a treatment of chronic obstructive Eustachian tube dysfunction.
