Pharyngeal Airway

Adolescents with a vertical skeletal growth pattern have a significantly narrower nasopharyngeal airway than those with a normal growth pattern. Airway and dental interventions are presented as potentially relevant to symptoms and airway health rather than guaranteed movement fixes. During open-mouth breathing, posterior teeth lose occlusal contact, promoting excessive posterior tooth eruption and backward-downward mandibular rotation that reinforces the long-face pattern in a self-perpetuating cycle. Prolonged open-mouth breathing alters tongue posture, disrupting the force balance between inner and outer dental arch surfaces and causing progressive narrowing of the upper arch. Symptoms such as headaches, ear infections, trouble sleeping, narrowness, restriction, or suspected upper airway problems may warrant evaluation beyond movement-only concerns. Craniofacial underdevelopment can narrow the upper airway and contribute to sleep apnea or upper airway resistance syndrome in some people. Mandibular retrognathia is a recognised risk factor for obstructive sleep apnoea, with documented consequences for maxillofacial development and psychological wellbeing in children and adolescent…
