Thermal welding versus bipolar tonsillectomy: a comparative study.

Area of Science:

• Otolaryngology
• Surgical Innovation
• Minimally Invasive Procedures

Background:

• Tonsillectomy is a common surgical procedure for chronic tonsillitis and obstructive sleep apnea.
• Traditional methods like bipolar electrocautery tonsillectomy (BET) can involve significant bleeding and postoperative pain.
• Advancements in surgical technology aim to improve patient outcomes and reduce complications.

Purpose of the Study:

• To compare the efficacy and safety of thermal welding tonsillectomy (TWT) against bipolar electrocautery tonsillectomy (BET).
• To evaluate key outcomes including intraoperative bleeding, operative time, postoperative pain, and recovery.
• To assess complication rates and return to normal diet following each procedure.

Main Methods:

• A prospective randomized study involving 150 adult patients undergoing tonsillectomy.
• Patients were randomly assigned to either TWT or BET groups.
• Exclusion criteria included history of peritonsillar abscess, bleeding disorders, and combined procedures.

Main Results:

• Thermal welding tonsillectomy (TWT) demonstrated no measurable intraoperative bleeding, compared to a mean of 16 mL in the bipolar electrocautery tonsillectomy (BET) group.
• Patients in the TWT group reported significantly lower postoperative pain and a quicker return to a normal diet.
• Hemorrhage rates were comparable for primary bleeding (1 BET), but secondary bleeding was lower in the TWT group (1 TWT vs. 3 BET).

Conclusions:

• Thermal welding tonsillectomy (TWT) is an effective procedure offering superior hemostasis compared to BET.
• TWT leads to reduced postoperative pain and faster patient recovery, including a quicker return to a normal diet.
• The findings suggest TWT may be a preferable alternative for tonsillectomy, particularly for adult patients.
