**Abstract**

Breathing is essential for life in all of its stages. Cellular, mitochondrial respiration requires an adequate supply of oxygen, provided by the air we breathe, after airway conduction, treatment by the lungs, and transport to tissues. At different stages of life, pediatric dentists and orthodontists can intervene in the upper airway, expanding it, which helps with ventilation. The greater airway space, if used, contributes in different ways to the child's development and the recovery of respiratory problems and should always be present as a weapon that physicians and the population should know. The value of the techniques becomes even more important when applied to children and young people with disabilities who can significantly improve their development and performance. Rapid Maxillary Expansion and Extraoral Traction Appliances are two important pediatric resources to treat these children. Clinical practice of the authors, is discussed, emphasizing the importance of early intervention and the need for multi and interdisciplinary collaboration in the follow-up of disabled people.
