Summary

Radiofrequency (Evac) tonsillectomy results in significantly less postoperative pain compared to monopolar electrosurgical (Bovie) tonsillectomy. Patients preferred the Evac technique in a blinded study.

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Pain Management

Background:

  • Previous research indicated reduced pain with radiofrequency (Evac) tonsillotomy versus monopolar electrosurgical (Bovie) tonsillectomy.
  • The clinical significance of tonsillotomy leaving a tonsil cuff is not fully understood.
  • Further investigation is warranted to compare pain levels between Evac tonsillectomy and Bovie tonsillectomy.

Purpose of the Study:

  • To compare the postoperative pain experienced by patients undergoing Evac tonsillectomy versus Bovie tonsillectomy.
  • To evaluate patient preference between the two surgical techniques.

Main Methods:

  • A prospective, blinded study design was employed.
  • Each participant had one tonsil removed using the Evac device and the other using the Bovie device.

  • Surgical time, blood loss, operative difficulty, and postoperative pain (days 1, 3, 5, 7, 10, 14) were recorded and analyzed.

    • Main Results:

    • Seventeen patients were analyzed.
    • Significantly less pain was reported with the Evac technique (P < 0.036).
    • The Evac technique was preferred by 12 out of 14 patients.

    Conclusions:

    • Evac tonsillectomy is demonstrably less painful than Bovie tonsillectomy.
    • Patients in a blinded setting preferred the Evac surgical technique.
    • The Evac device offers a significant reduction in postoperative pain.
