Medicana Bursa Hospital150 enrolled

Overview

This prospective, non-randomized observational study compared the surgical outcomes of BiZact™, Coblation, and Bipolar tonsillectomy techniques in pediatric and adult patients. Operative efficiency, postoperative pain, recovery parameters, postoperative bleeding, and device-related costs were evaluated.

Tonsillectomy is a commonly performed surgical procedure in otorhinolaryngology, and various techniques have been developed to improve operative efficiency and postoperative recovery. This prospective, non-randomized observational study included 150 patients aged 5-40 years who underwent tonsillectomy between November 2024 and September 2025. Patients were allocated to Bipolar, Coblation, or BiZact tonsillectomy groups based on surgeon preference and device availability. Primary outcome measures were operative time and postoperative pain assessed using the visual analogue scale on postoperative days 1, 3, and 7. Secondary outcomes included time to first solid food intake, length of hospital stay, postoperative bleeding, bleeding management, and device-related cost. The study aimed to compare clinical outcomes, recovery profiles, and procedural efficiency among the three tonsillectomy techniques.

Outcomes

Primary Outcomes

Postoperative pain (Visual Analog Scale score)

Postoperative pain was assessed using the Visual Analog Scale (VAS), a 10-cm scale ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst pain imaginable. Higher scores represent greater pain intensity.

Time frame: Postoperative days 1, 3, and 7

Surgery time

Time frame: During surgery

Secondary Outcomes

Time to first solid food intake

Time frame: Within the first postoperative week

Length of hospital stay

Duration of hospitalization measured in days following tonsillectomy.

Time frame: Postoperative Day 1

Postoperative bleeding

Time frame: Up to 30 days postoperatively

Device cost per case

Cost of the surgical device used for tonsillectomy, calculated per patient.

Time frame: Perioperative period (day of surgery)
