Coblation versus BiZact extra-capsular tonsillectomy in adults: a randomized control trial

Area of Science:

• Otolaryngology
• Surgical Innovation
• Pain Management

Background:

• Tonsillectomy is common but causes significant postoperative pain and bleeding.
• Coblation and BiZact devices are alternatives for tonsillectomy, with prior claims of favorable pain outcomes.
• Direct comparative studies are needed to evaluate their efficacy in reducing pain and bleeding.

Purpose of the Study:

• To directly compare the postoperative pain and bleeding outcomes of Coblation and BiZact tonsillectomy techniques.
• To evaluate secondary outcomes including surgical duration, intra-operative bleeding, and return to normal activities.
• To determine the optimal device for adult tonsillectomy regarding patient comfort and surgical safety.

Main Methods:

• A single-blinded, randomized controlled trial involving 61 patients undergoing tonsillectomy.
• Patients were randomized to either the BiZact or Coblation device group.
• Postoperative pain was assessed using a Visual Analogue Scale for 14 days, with secondary outcomes including bleeding and recovery time.

Main Results:

• Coblation demonstrated significantly lower pain on postoperative day 1 (P < 0.05).
• BiZact showed significantly reduced pain on postoperative days 7 and 11 (P < 0.05).
• BiZact was associated with longer hemostasis time (P < 0.001) and greater intraoperative blood loss (P < 0.01), with a trend towards more secondary bleeding.

Conclusions:

• Both Coblation and BiZact are safe and effective for adult tonsillectomy.
• Coblation's advantage in early postoperative pain may make it more suitable for day-case procedures.
• Further research is needed to confirm the trend in secondary bleeding rates for the BiZact device.
