Adenoidectomy, Tonsillectomy in Childhood Tied to Risk for Adult Chronic Rhinosinusitis
A new multicenter retrospective study of over 100 U.S. health‑care organizations links pediatric adenotonsillectomy performed for infectious indications to higher rates of adult chronic rhinosinusitis (CRS). Children who underwent adenoidectomy alone showed a 55% increased hazard of CRSsNP, while combined tonsillectomy‑adenoidectomy for tonsillitis or adenoiditis raised risks of CRSwNP (HR 1.63) and subsequent sinus surgery (HR 1.97). In contrast, surgeries performed for obstructive sleep apnea did not elevate CRS incidence. The authors suggest that underlying infection susceptibility, rather than the surgery itself, may drive these long‑term outcomes.
