Postoperative pain following coblation tonsillectomy: randomized clinical trial

Area of Science:

• Otolaryngology
• Surgical Innovation
• Pain Management

Background:

• Tonsillectomy is a common procedure with significant postoperative pain.
• Coblation (cold ablation) is a newer technique claiming reduced pain.
• This study compares coblation to standard dissection for tonsillectomy pain.

Purpose of the Study:

• To compare postoperative pain levels between coblation and dissection tonsillectomy.
• To evaluate the efficacy of coblation in reducing pain after tonsillectomy.
• To assess the duration of pain reduction with coblation.

Main Methods:

• A randomized, paired-comparison study involving 20 adult patients.
• Each patient had one tonsil removed via coblation and the other via dissection.
• Postoperative pain was assessed daily for 10 days using a visual analogue scale.

Main Results:

• Coblation tonsillectomy showed significantly less pain on postoperative days 1, 2, and 3 (P < 0.001, P = 0.003, P = 0.018, respectively).
• No significant difference in pain levels was observed between the techniques from day 4 to day 10.
• Early postoperative pain reduction was statistically significant with coblation.

Conclusions:

• Coblation tonsillectomy provides significant pain relief during the initial three days post-surgery.
• The pain-reducing benefits of coblation do not extend beyond the first three days.
• Coblation is a potentially advantageous technique for adult day-case tonsillectomy, particularly for chronic or recurrent tonsillitis.
