Radiofrequency tonsillotomy in Sweden 2009-2012

Area of Science:

• Otolaryngology
• Pediatric Surgery
• Health Services Research

Background:

• Tonsillotomy is increasingly used for pediatric upper airway obstruction.
• Radiofrequency (RF) instruments are prevalent in tonsillotomy procedures.
• Data on specific RF instrument outcomes in pediatric tonsillotomy are limited.

Purpose of the Study:

• To categorize instruments used for tonsillotomy in Sweden.
• To compare the outcomes and complication rates of different RF instruments for pediatric tonsillotomy.
• To evaluate the effectiveness of RF tonsillotomy for upper airway obstruction.

Main Methods:

• Retrospective analysis of data from the Swedish National Registry for Tonsil Surgery (2009-2012).
• Inclusion of 1,676 children (aged 2-18) undergoing tonsillotomy for upper airway obstruction.
• Categorization of instruments, focusing on radiofrequency devices (Coblation®, Surgitron®, CURIS®).

Main Results:

• Radiofrequency instruments were used in 96% of cases.
• Low postoperative bleeding rate (1.2%) and high symptom relief (95.1%) were observed.
• No significant differences in bleeding, infection, or symptom relief between RF instruments; Coblation® associated with more days on analgesics.

Conclusions:

• Radiofrequency tonsillotomy is the dominant technique for pediatric upper airway obstruction in Sweden.
• The choice of RF instrument does not significantly impact key outcomes like bleeding or symptom relief.
• While generally comparable, Coblation® may require a slightly longer period of analgesia post-procedure.
