Summary

A new electrosurgical device significantly speeds up tonsillectomies and reduces blood loss compared to traditional methods. Postoperative pain and bleeding were similar, suggesting the device is a safe and efficient alternative for tonsil removal.

Area of Science:

  • Otorhinolaryngology
  • Surgical Technology
  • Minimally Invasive Procedures

Background:

  • Tonsillectomy is a common surgical procedure.
  • Novel electrosurgical instruments aim to improve efficiency and patient outcomes.
  • Comparative studies are needed to validate new surgical device performance.

Purpose of the Study:

  • To compare the efficacy of a novel electrosurgical temperature-controlled instrument against cold-steel tonsillectomy with cauterization.
  • To assess surgical time, intraoperative blood loss, and postoperative pain.
  • To evaluate the safety profile of the new device in tonsillectomy.

Main Methods:

  • A randomized self-controlled clinical trial involving 48 patients.
  • Each patient underwent tonsillectomy using the novel device on one side and cold-steel with cauterization on the other.
  • Primary outcomes included tonsil removal time and bleeding cessation time; secondary outcomes assessed pain and bleeding events.

Main Results:

  • Device-assisted tonsillectomies were significantly faster (mean difference 209s, p<0.001).
  • Intraoperative blood loss was significantly lower with the novel device (p<0.05).
  • Postoperative pain and bleeding were comparable between the two methods; two secondary bleeding events occurred on the control side.

Conclusions:

  • The novel electrosurgical device reduces tonsillectomy surgical time and intraoperative blood loss.
  • The device demonstrated comparable postoperative pain and bleeding outcomes to traditional methods.
  • This instrument offers a potentially beneficial alternative in time-constrained surgical settings, especially after a learning curve.
