Tonsillectomy or tonsillotomy? A systematic review for paediatric sleep-disordered breathing

Area of Science:

• Otolaryngology
• Pediatric Surgery
• Sleep Medicine

Background:

• Recent evidence questions tonsillectomy for pediatric sleep-disordered breathing.
• Tonsillotomy is proposed as a less invasive alternative with comparable effectiveness.
• Potential for improved cost-effectiveness due to reduced post-operative morbidity.

Purpose of the Study:

• To systematically review literature comparing tonsillotomy and tonsillectomy.
• Evaluate clinical efficacy, post-operative morbidity, and cost-effectiveness.
• Focus on pediatric patients (<16 years) with sleep-disordered breathing.

Main Methods:

• Systematic search of MEDLINE, EMBASE, and CENTRAL (1984-July 2014).
• Inclusion of English papers directly comparing tonsillotomy and tonsillectomy outcomes.
• Independent assessment of studies by two authors, with third author for disagreements.

Main Results:

• 32 studies (19 randomized, 13 non-randomized) met criteria.
• No significant differences in patient satisfaction, quality-of-life, or polysomnographic improvement.
• Tonsillotomy significantly reduced secondary hemorrhage (79%), post-operative pain, and time to normal oral intake, with fewer readmissions.

Conclusions:

• Tonsillotomy is supported for children with obstructive indications.
• Likely to reduce post-operative bleeding, pain, and speed recovery.
• Decreased healthcare burden due to fewer complications; further research on recurrence and hemorrhage severity is needed.
