This article reviews the dentofacial disorders seen in children with upper airway obstruction and a medical history of sleep-related breathing disorders. In spite of being an object of study for a lot of time, the cause and effect relationship continues being controversial. Is oral breathing in children (consequence of upper airways obstruction), the main cause of sleep-related breathing disorders? Is oral breathing the one that carries to the alteration of the dentofacial development? These questions led us to realize an interdisciplinary study where an otorhinolaryngologist and an orthodontist evaluated all the parameters. The diagnosis of respiratory problems that affect children’s dentofacial development is essential because surgical removal of adenoids and/or tonsils can help to normalize breathing, and as a result, although not completely, the growth pattern.
