Summary

Thermal welding tonsillectomy (TWT) offers lower postoperative pain and reduced uvula edema compared to ligasure tonsillectomy (LT). Both methods ensure safety and hemostasis for tonsil removal.

Area of Science:

Otolaryngology
Surgical Technology
Minimally Invasive Procedures

Background:

Tonsillectomy is a common surgical procedure for chronic tonsillitis and obstructive sleep apnea.
Evaluating different tonsillectomy techniques is crucial for optimizing patient outcomes.
Thermal welding tonsillectomy (TWT) and ligasure tonsillectomy (LT) are modern hemostatic techniques.

Purpose of the Study:

To compare thermal welding tonsillectomy (TWT) with ligasure tonsillectomy (LT).
To assess key surgical parameters including bleeding, operative time, pain, and complications.

Main Methods:

Prospective randomized study involving 143 adult patients.
Patients were randomly assigned to either TWT or LT groups.
Evaluated intraoperative bleeding, operative time, postoperative pain (VAS), and complication rates.

Laminectomy for the Removal of Thoracic Ossification of the Ligamentum Flavum (TOLF) Using Ultrasonic and Conventional Osteotomes

Published on: April 21, 2023

Main Results:

No significant intraoperative bleeding observed in either group.
Mean operative time showed no significant difference between TWT and LT.
Significantly lower mean postoperative pain scores and mild uvula edema in the TWT group.
Late postoperative hemorrhage occurred in 1 TWT patient and 2 LT patients.

Conclusions:

Both TWT and LT provide effective hemostasis and reduced operative time.
TWT demonstrates advantages in reduced postoperative pain and mild uvula edema.
The use of single-use instruments in both TWT and LT ensures safety against transmissible diseases.
