Which structural issue most commonly causes pediatric mouth breathing and may require surgical intervention?
Answer: Enlarged adenoids or tonsils
Enlarged adenoids or tonsils are the most common structural cause of pediatric mouth breathing and may require adenotonsillectomy before myofunctional therapy.
How does chronic mouth breathing affect facial development in children?
Answer: Longer, narrower face with a high palatal arch
Chronic mouth breathing leads to adenoid facies: a long, narrow face, high palatal vault, and dental crowding due to altered muscle forces on developing bone.
What is the primary role of the diaphragm in proper nasal breathing mechanics?
Answer: It is the primary muscle of inhalation creating negative pressure
The diaphragm is the primary inspiratory muscle; its contraction creates negative thoracic pressure that draws air through the nasal passages during proper breathing.
A patient reports waking with a dry mouth and sore throat every morning. Which myofunctional issue does this MOST suggest?
Answer: Nocturnal mouth breathing
Dry mouth and sore throat upon waking are classic signs of nocturnal mouth breathing, where oral airflow desiccates mucosal tissues overnight.
Which oropharyngeal exercise has research support for reducing snoring and mild sleep apnea severity?
Answer: Tongue and soft palate strengthening exercises
Studies, including a 2009 RCT by Guimarães et al., show that tongue and soft palate exercises significantly reduce snoring frequency and apnea-hypopnea index scores.
In myofunctional therapy, 'nasal patency' refers to what?
Answer: Clear, unobstructed airflow through the nasal passages
Nasal patency means the nasal airway is sufficiently open and clear to allow adequate airflow for comfortable nasal breathing at rest.
