Which cranial nerve primarily innervates the muscles of mastication that a myofunctional therapist must assess?
Answer: CN V (Trigeminal)
The trigeminal nerve (CN V) provides motor innervation to the masseter, temporalis, and pterygoid muscles used in mastication.
A patient cannot achieve tongue tip elevation to the spot without jaw opening. Which compensatory pattern does this indicate?
Answer: Tongue tie (ankyloglossia) or reduced tongue tip mobility requiring further assessment
Inability to elevate the tongue tip independently of the jaw suggests restricted lingual mobility, often associated with ankyloglossia or hypotonicity requiring further evaluation.
Which sequence correctly describes the phases of a normal adult swallow?
Answer: Oral preparatory → oral transport → pharyngeal → esophageal
The normal swallow progresses from oral preparation, to oral transport, then pharyngeal, and finally esophageal phases in that order.
When a child presents with 'mouth breathing face' morphology, which skeletal change is most commonly observed?
Answer: Increased lower anterior face height with narrow maxillary arch
Chronic mouth breathing promotes downward and backward mandibular rotation, increasing lower anterior face height and allowing the maxillary arch to narrow from lack of tongue pressure.
A patient demonstrates correct tongue posture in the clinic but reverts to low tongue position at home. What is the BEST next therapeutic step?
Answer: Introduce environmental reminder cues and self-monitoring logs for home
Environmental cues such as stickers or phone reminders paired with self-monitoring logs extend therapeutic learning into the home environment to facilitate carryover.
Which breathing exercise is used in myofunctional therapy to increase diaphragmatic activation and reduce accessory muscle use?
Answer: Diaphragmatic breathing with lateral rib expansion and relaxed shoulders
Diaphragmatic breathing with lateral rib expansion trains efficient nasal breathing mechanics while reducing reliance on accessory neck and shoulder muscles.
Which disorder is myofunctional therapy CONTRAINDICATED as a primary standalone treatment without prior medical management?
Answer: Obstructive sleep apnea in an adult with enlarged tonsils causing airway obstruction
Obstructive sleep apnea with a structural cause such as tonsillar hypertrophy requires medical or surgical management before myofunctional therapy can be effectively applied.
