Does Removing Tonsils and Adenoids Improve a Child's Posture?

Adenotonsillectomy — removing the adenoids and tonsils — is a common way to clear an obstructed child's airway. Its effects on the nasal space and jaw are well documented. This study asked a question that had gone largely unexamined: when you open the airway, does the child's posture change too?

The researchers measured the position of the head, cervical and thoracic spine, and shoulder girdle in 49 mouth-breathing children, before surgery and again afterward, using motion-capture kinematics. The design treats posture as something that might follow the airway — that the forward head and rounded shoulders are downstream effects, not permanent features.

This matters because it tests reversibility. If posture improves once a child can finally breathe through their nose, it confirms that the slumped, head-forward stance many mouth breathers adopt is a compensation, not their fixed anatomy. That distinction changes how early intervention is justified: you're not just clearing an airway, you may be releasing the whole body from a posture it never needed to hold.
