Abstract: Skeletal class Ⅱ malocclusion is a prevalent developmental dentofacial anomaly that affects not only facial esthetics and stomatognathic function but is also intimately linked to respiratory function. Patients presenting with this deformity exhibit a significantly higher prevalence of obstructive sleep apnea-hypopnea syndrome. While orthodontic treatment can modify dentofacial structures and improve facial profiles to varying degrees，it simultaneously exerts an impact on the morphology and physiological function of the upper airway. This article provides a comprehensive review of current researches regarding common assessment modalities for the upper airway，the correlation between skeletal class Ⅱ malocclusion and airway constriction，and the specific effects of various orthodontic therapeutic strategies on the upper airway in patients with skeletal class Ⅱ malocclusion and mandibular retrusion.

Key words: orthodontic treatment, skeletal class Ⅱ malocclusion, upper airway
