What type of breathing pattern is considered dysfunctional and a primary focus of myofunctional therapy?
Answer: Mouth breathing
Mouth breathing is a dysfunctional pattern that bypasses nasal filtration, humidification, and nitric oxide production, and is a core target of myofunctional therapy.
Which nasal function is lost when a patient habitually mouth breathes?
Answer: Nitric oxide production
The nasal passages produce nitric oxide, a vasodilator that improves oxygen uptake in the lungs, which is bypassed during chronic mouth breathing.
Upper airway resistance syndrome (UARS) is most closely associated with which myofunctional dysfunction?
Answer: Low tongue posture
Low or improper tongue posture reduces oral airway support and contributes to upper airway collapse, which is characteristic of UARS.
A myofunctional therapist notices a patient has chronic nasal congestion that prevents nasal breathing. What is the FIRST recommended action?
Answer: Refer to an ENT or allergist
Structural or medical causes of nasal obstruction must be addressed by an ENT or allergist before nasal breathing training can succeed.
Which condition is directly worsened by low tongue posture and weak oropharyngeal muscles?
Answer: Obstructive sleep apnea
Obstructive sleep apnea is exacerbated by weak oropharyngeal and tongue muscles that collapse during sleep, reducing airway patency.
The Buteyko breathing method used in myofunctional therapy primarily addresses which issue?
Answer: Overbreathing and low CO2 tolerance
Buteyko breathing aims to reduce chronic overbreathing and improve carbon dioxide tolerance, which helps restore nasal breathing patterns.
