| ABSTRACT |
Background and Objectives
To compare the perioperative and postoperative outcomes of tonsillectomy performed using BiZact and the monopolar cautery.
Subjects and Method
This retrospective study, conducted at a single-institution by a single-surgeon, included patients of all ages who underwent tonsillectomy between January 2023 and December 2025. Patients were grouped according to the device used, BiZact or the monopolar cautery. The age-stratified subgroup analyses were performed for pediatric (≤18 years) and adult (≥19 years) patients. Operative time, postoperative bleeding, and pain-related outcomes were reviewed from medical records. Continuous variables were compared using the Mann-Whitney U test, and categorical variables using the chi-square test or Fisher’s exact test.
Results
The operative time was shorter in the BiZact group in both pediatric patients (25.3 ±7.3 min vs. 34.8±16.7 min; p<0.001) and adult patients (19.8±7.0 min vs. 28.1±11.9 min; p=0.001). In the pediatric subgroup, the use of in-hospital pro re nata (PRN) analgesics (16.2% vs. 26.8%; p=0.048) and additional analgesic prescriptions at the first postoperative visit (21.5% vs. 40.9%; p=0.001) were less frequent in the BiZact group. In the adult subgroup, additional analgesic prescriptions at the first postoperative visit were also less frequent in the Bi-Zact group (47.5% vs. 85.7%; p<0.001), whereas the use of in-hospital PRN analgesics did not differ significantly. Postoperative bleeding outcomes were similar between the two groups in both age subgroups.
Conclusion
The BiZact tonsillectomy was associated with shorter operative time in both pediatric and adult patients and with reduced postoperative analgesic requirement, particularly in the pediatric patients, while postoperative bleeding outcomes were similar between groups. These findings support BiZact as a useful alternative device for tonsillectomy. |
