BackgroundRecent evidence has challenged the practice of tonsillectomy in children with sleep-disordered breathing. Tonsillotomy (subtotal/partial/intracapsular tonsillectomy) has been proposed as an alternative with equivalent effectiveness and decreased post-operative morbidity, thus improving cost-effectiveness.ObjectiveTo systematically review the literature comparing clinical efficacy, post-operative morbidity, and cost-effectiveness of tonsillotomy and tonsillectomy in paediatric (<16yo) patients with sleep-disordered breathing.Data sourcesA systematic search of MEDLINE, EMBASE, and CENTRAL (1984–July 2014) was conducted. Papers in English directly comparing post-operative outcomes in tonsillectomy and tonsillotomy in children undergoing surgery for sleep-disordered breathing were included.Review methodsTwo authors independently assessed abstracts for relevance, with disagreements resolved by a third author. Selected studies were independently assessed regarding inclusion and exclusion criteria.ResultsThirty-two studies satisfied inclusion and exclusion criteria (19 randomised, 13 non-randomised). Patient satisfaction, quality-of-life, and polysomnographic improvement post-surgery did not vary between tonsillotomy and tonsillectomy. Tonsillotomy reduced the odds of a secondary haemorrhage by 79% (OR 0.21, 95% CI 0.17–0.27, p < 0.01), decreased post-operative pain and reduced return to normal oral intake by 2.8 days (95% CI 1.08–4.52, p < 0.01). The odds of readmission were decreased by 62% (OR 0.38, 95% CI 0.23–0.60, p < 0.01). Tonsillotomy had a slightly higher rate of symptom recurrence (4.51%) than tonsillectomy (2.55%), the long-term impact of which was unclear.ConclusionCurrent evidence supports tonsillotomy in children with obstructive surgical indications. It is likely to reduce post-operative haemorrhage, pain, and facilitate a faster return to normal diet and activity. Healthcare burden is decreased due to fewer post-operative complications and reduced need for medical re-contact. More research is necessary to assess the risk of recurrence, and further classification of secondary haemorrhage severity is required to fully clarify the clinical benefit of tonsillotomy.
