Coblation intra-capsular tonsillectomy: A prospective tertiary center trial

Area of Science:

• Otolaryngology
• Pediatric Surgery
• Sleep Medicine

Background:

• Intra-capsular coblation tonsillectomy (ICT) is gaining traction for pediatric obstructive sleep apnea (OSA).
• Evidence comparing intra-capsular tonsillectomy (IT) techniques for efficacy and morbidity remains inconclusive.
• This study objectively assesses ICT's post-operative morbidity and effectiveness.

Purpose of the Study:

• To evaluate the effectiveness of intra-capsular coblation tonsillectomy (ICT) in treating pediatric obstructive sleep apnea (OSA).
• To objectively measure post-operative morbidity associated with ICT in children.
• To compare ICT with other intra-capsular tonsillectomy (IT) techniques regarding outcomes and complications.

Main Methods:

• Prospective enrollment of 107 children undergoing ICT (with or without adenoidectomy) for tonsillar hypertrophy.
• Efficacy assessed using pre- and post-operative Obstructive Sleep Apnea score (OSA-18).
• Morbidity measured via Parent's Post-operative Pain Measure (PPPM), pain medication use, diet/activity resumption, and complication rates (dehydration, bleeding).

Main Results:

• Significant improvement in OSA-18 scores post-ICT (78.77 to 23.7, p < 0.001).
• Low Parent's Post-operative Pain Measure (PPPM) scores observed at all evaluation points.
• Rapid recovery noted: normal diet by 2.42 days, normal activity by 2.7 days, with minimal analgesic use (acetaminophen for 1.93 days).
• No hospital readmissions or post-operative hemorrhages reported.

Conclusions:

• Intra-capsular coblation tonsillectomy (ICT) is an effective and safe treatment for pediatric upper airway obstruction due to tonsillar hypertrophy.
• The procedure demonstrates minimal post-operative morbidity and rapid recovery.
• ICT warrants broader consideration for treating pediatric tonsillar hypertrophy and associated OSA.
