Abstract
|
|
|
Balloon eustachian tuboplasty (BET), a surgical technique to expand the cartilaginous portionof the eustachian tube by ballooning via opening at the nasopharynx, has been introduced as auseful surgical modality for eustachian tube dysfunction patients. Although BET is known asa relatively safe procedure, we recently have experienced two cases of cardiac complicationsduring balloon inflation. In one case, an asystole occurred for 13 seconds during this procedure;the heart rate was recovered after balloon deflation with an intravenous injection of glycopyrrolateand atropine. In the other case, bradycardia occurred and continued during BET.
Heart rate was recovered immediately after deflation of balloon without drug injection. As faras we know, this is the first report of cardiac complications during BET, probably related withtrigemino-cardiac reflex. In both cases, no other sequelae remained after the surgery. We reportthese two cases of cardiac complications that occurred during BET along with a reviewof literature.
