Abstract: The airway plays an extremely important role in healthy sleep and breathing. Narrow upper airways can induce sleep-disordered breathing. In severe cases，patients may show symptoms related to obstructive sleep apnea-hypopnea syndrome. The factors affecting upper airway morphology can be categorized into hard tissue factors，deciding the shape and position of the jaws，and soft tissue factors，influencing the position and volume of the tongue and soft palate. Therefore，the skeletal structure and characteristics of various malocclusions associated with upper airway morphology have great impact on airway health. This article reviews the research progress on the correlation between different types of malocclusion and upper airway morphology，so as to provide references for the improvement in clinical diagnosis and treatment.

Key words: malocclusion, airway morphology, obstructive sleep apnea-hypopnea syndrome, maxillofacial skeletal morphometric features
