Sleep-Disordered Breathing, Orofacial Growth, and Prevention of Obstructive Sleep Apnea

Abstract

Abnormal breathing during sleep is related to intrinsic and extrinsic factors that are present early in life. Investigation of fetal development and early-in-life orofacial growth allows recognition of risk factors that lead to change in upper airway patency, which leads to abnormal upper airway resistance, abnormal inspiratory efforts, and further increase in resistance and progressive narrowing of the collapsible upper airway. Such evolution can be recognized by appropriate clinical evaluation, specific polysomnographic patterns, and orofacial imaging. Recognition of the problems should lead to appropriate treatments and prevention of obstructive sleep apnea and its comorbidities.
