Safety of Adenotonsillectomy in Children with Genetic Syndromes.

OBJECTIVES

Children with genetic syndromes, especially Down syndrome (DS), are considered high-risk candidates for adenotonsillectomy (AT) due to anatomical abnormalities and comorbidities. This study aimed to evaluate the safety of AT in patients with DS and other genetic syndromes (OS).

METHODS

This retrospective study included 62 syndromic patients (46 DS, 16 OS) under 18 years of age who underwent tonsillectomy ± adenoidectomy ± ventilation tube (VT) insertion between 2010 and 2025. Demographics, comorbidities, surgical details, complications, and hospital stays were reviewed.

RESULTS

Indications included sleep-disordered breathing (51/62, 82.3%) and recurrent tonsillitis (16/62, 25.8%). Procedures performed were AT (51/62, 82.3%) or tonsillectomy alone (11/62, 17.7%) ± VT insertion (16/62, 25.8%). Median hospital stay was 1 day (IQR: 1-1), with 93.5% (58/62) discharged after 1 day. Two-day stays occurred in 18.75% of OS patients (3/16) and 2.2% of DS patients (1/46). Planned intensive care unit admission was required in 2 OS patients (3.2%). No emergency admissions or perioperative mortality occurred. Overall complication rate was 8.1% (5/62)-8.7% in DS and 6.3% in OS (P = 1.00)-including bleeding requiring reoperation (1/62, 1.6%), respiratory event (1/62, 1.6%), and insufficient oral intake (3/62, 4.8%).

CONCLUSION

AT appears to be safe in children with genetic syndromes, with low rates of complications.
