Tonsillectomy using the BiZact: A pilot study in 186 children and adults

Abstract

1.The BiZact tonsillectomy device, produced by Medtronic (Minneapolis, MN, USA), was approved for market use in Australia by the Therapeutics Good Administration (TGA) in 2016 and is a new device for tonsillectomy

2.Results from this pilot study of 186 patients demonstrate a post‐operative hemorrhage rate of 4.3% similar to rates described by other studies.

3.BiZact tonsillectomy allows for a shortened operative time in the hands of both experienced and training surgeons with a median time of 5.1 minutes (range 1.5 – 26.5 minutes).

4.BiZact tonsillectomy is associated with reduced intraoperative blood loss with less than 1mL of blood loss observed in 71 (38.2%) cases and between 1‐10mL loss observed in 81 (43.5%) cases in this report.

5.This study demonstrates safety and feasibility of this device as a pilot study towards undertaking a prospective randomized trial comparing it to other tonsillectomy techniques.
