Bipolar scissors tonsillectomy significantly reduces surgical time and blood loss compared to cold dissection. Both methods show similar patient morbidity and complication rates, making bipolar scissors a safe alternative.

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Minimally Invasive Procedures

Background:

  • Tonsillectomy is a common surgical procedure for chronic or recurrent tonsillitis.
  • Traditional cold dissection tonsillectomy has known limitations regarding blood loss and operative time.

Purpose of the Study:

  • To compare the efficacy and safety of bipolar scissors tonsillectomy with traditional cold dissection tonsillectomy.
  • To evaluate intraoperative bleeding, operative time, postoperative pain, and complication rates.

Main Methods:

  • Prospective, randomized, multi-unit study involving 200 patients undergoing tonsillectomy.
  • Comparison of bipolar scissors technique versus cold dissection method.
  • Outcome measures included blood loss, operative duration, pain scores, and hemorrhage rates.

Main Results:

  • Bipolar scissors tonsillectomy demonstrated significantly less intraoperative blood loss (5 mL vs. 115 mL) and shorter operative time (13 min vs. 20 min) compared to cold dissection (P < .001).
  • No statistically significant difference was found in postoperative pain scores between the two methods.
  • Overall primary hemorrhage rate was 2.1%, secondary hemorrhage rate was 16.9%, and hospital readmission rate was 10.3%, unaffected by surgical method.

Conclusions:

  • Bipolar scissors tonsillectomy is a safe and effective alternative to cold dissection.
  • This technique offers significant advantages in reducing surgical time and intraoperative blood loss.
  • Morbidity and complication rates are comparable between the two tonsillectomy methods.
