Surgical treatment for childhood obstructive sleep apnoea: Cold-knife tonsillar dissection versus bipolar...

Area of Science:

• Otolaryngology
• Pediatric Sleep Medicine
• Surgical Techniques

Background:

• Childhood obstructive sleep apnea (OSA) is effectively treated with adenotonsillectomy.
• Partial surgical techniques are increasingly used to mitigate postoperative discomfort and complications.
• Comparing total tonsillectomy with radiofrequency ablation (RFA) is crucial for optimizing treatment outcomes.

Purpose of the Study:

• To compare the efficacy and safety of total tonsillectomy versus bipolar radiofrequency ablation (RFA) in treating childhood obstructive sleep apnea.
• To evaluate the resolution rates of sleep apnea and clinical symptom improvement one year post-surgery.
• To assess and compare the incidence of surgical and anesthetic complications between the two techniques.

Main Methods:

• A comparative study involving 96 children undergoing total tonsillectomy (cold dissection) and 101 children undergoing RFA.
• Polysomnography was conducted pre-operatively and one year post-operatively for all participants.
• Outcomes measured included persistent obstructive sleep apnea (apnea-hypopnea index ≥ 3) and clinical symptom resolution.

Main Results:

• Syndrome persistence rates were similar: 25% for cold dissection and 22.77% for RFA.
• Anesthetic complication rates were low and comparable (5% for cold dissection, 4.2% for RFA).
• Postoperative bleeding rates were minimal and statistically similar between both surgical groups.

Conclusions:

• Both cold dissection tonsillectomy and bipolar radiofrequency ablation are safe treatment options for pediatric obstructive sleep apnea.
• There are no statistically significant differences in the resolution rates of obstructive sleep apnea between the two techniques.
• The choice of technique can be based on optimizing patient outcomes and minimizing procedural risks.
