Dissection versus diathermy for tonsillectomy.

Area of Science:

• Otolaryngology
• Surgical Techniques
• Evidence-Based Medicine

Background:

• Tonsillectomy is a common surgical procedure with various methods.
• The superiority of one tonsillectomy technique over another is not clearly established.

Purpose of the Study:

• To compare the morbidity associated with tonsillectomy using dissection versus diathermy techniques.

Main Methods:

• Systematic review of randomized controlled trials comparing dissection and diathermy tonsillectomy.
• Searched multiple databases including Cochrane, PubMed, EMBASE, CINAHL, Web of Science, and ISRCTN up to October 2010.
• Two independent reviewers selected studies, extracted data, and assessed risk of bias.

Main Results:

• Two studies with 254 participants were included, showing low risk of bias.
• Diathermy techniques resulted in reduced intraoperative bleeding compared to cold dissection.
• Increased postoperative pain was observed in the diathermy group, with no significant difference in secondary bleeding rates.

Conclusions:

• Insufficient data exists to definitively declare one tonsillectomy method superior.
• Evidence suggests monopolar dissection diathermy may lead to greater pain.
• Large, well-designed randomized controlled trials are required to identify the optimal tonsillectomy method.
