Abstract

INTRODUCTION: Over 550,000 tonsillectomies are performed every year. While post-tonsillectomy hemorrhage (PTH) has been studied in the coblator, bovie, and cold steel technique, there is a dearth of studies examining the post-tonsillectomy outcome using BiZact. This study examines the rate of BiZact PTH requiring control of hemorrhage in the OR and assess resident comfort using the device.

METHODS: Retrospective chart review for all tonsillectomies performed between January 2018 and December 2020 were performed. Rates of PTH were analyzed. In addition, a 7-question BiZact resident experience survey was administered to 25 otolaryngology residents.

RESULTS: 1384 patients were included in this study; 444 (32%) Bizact and 940 (68%) Coblation. 11 (2.48%) BiZact patients had PTH requiring OR for control of hemorrhage, compared to 44 (4.68%) Coblation patients. There were no patient deaths because of PTH. The mean age of patients with PTH was 7.44 (SD 4.07) years old. 22 (88%) residents responded to the survey. 17 (77.27%) felt more confident with Coblator while performing tonsillectomy most commonly reported for ease of use, followed by BiZact 4 (18.18%), most commonly reported for improved surgical plane.

CONCLUSION: BiZact is a safe and effective addition. At our institution, the rate of secondary PTH requiring OR intervention for BiZact is comparable to the national average for other tonsillectomy devices. The rate of BiZact PTH requiring OR intervention in our experience was nearly half of those done with Coblator. Overall residents at SCHC preferred Coblator over BiZact mainly attributed to Coblator's versatility and ability to control intraoperative tonsil bleeding without additional instruments despite BiZact's shorter operative time.
