Tonsil removal associated with improved asthma

Adenotonsillectomy (AT) in childhood is associated with significant improvements in asthma outcomes, according to a large US study.

More than 40,000 children with asthma were studied, including 13,000 post AT and 27,000 age, sex and geographically matched controls.

Data showed that in the year after AT, children had 30% fewer acute asthma exacerbations compared with the year before.
