A practical use of a 16-gauge peripheral angiocatheter as an aspiration cautery in endoscopic ear surgery

Otol Neurotol. 2014 Aug;35(7):1123-4. doi: 10.1097/MAO.0000000000000387.

Abstract

Objective: To define a technique for the practical use of a 16-gauge peripheral venous catheter as an insulated aspiration cautery in endoscopic ear surgery.

Study design: Retrospective case review.

Setting: Tertiary referral center.

Materials and methods: A 16-gauge intravenous catheter was prepared as a cauterization instrument with aspiration. After simple rearrangement of the exterior plastic portion, it was connected to a suction system. With the help of an unipolar cautery, aspiration of the blood and homeostasis was achieved.

Results: Hemorrhage of the external ear canal skin after incision can be easily coagulated with this instrument. During follow-up, there were no wound infection, facial nerve paresis, scar formation, and inadvertent burn of the external canal and auricular skin.

Conclusion: With the help of this instrument, bleeding control during incision can be easily maintained. It is a simple, easily prepared, and alternative homeostasis technique in endoscopic ear surgery.
