MPV Values in Children with Adenoid Hy-pertrophy and Correlation with Adenoid Size

Esra Akyüz Ozkan
Background: Adenoid hypertrophy (AH) leads to chronic upper airway obstruction. Upper airway obstruction may cause pulmonary hypertension and right ventricle dysfunction. Mean platelet volume (MPV) may be used as a marker of platelet activation and it is shown that MPV is related to cardiovascular disorders. We investigated in our study if MPV is correlated with adenoid size and can be used as an indicator of obstruction due to adenoid hypertrophy. Methods: 95 children with AH and 99 healthy con...
