CMT Evaluation & Treatment Planning 3 — Questions and Answers
Question 1: A CMT therapist is evaluating an adult patient who reports neck pain and TMJ clicking. Which myofunctional assessment finding would MOST likely connect these symptoms?
- Bilateral masseter hypertrophy with clenching habit (Correct answer)
- Anterior tongue thrust with low resting posture
- Lip incompetence during speech
- Restricted lingual frenum affecting tongue-tip elevation
Correct answer: Bilateral masseter hypertrophy with clenching habit
Masseter hypertrophy from clenching increases joint loading, which can cause TMJ clicking and associated cervical muscle tension.
Question 2: When evaluating a lingual frenum, which clinical finding would MOST indicate a referral for frenectomy prior to myofunctional therapy?
- Mild restriction limiting tongue tip to 10 mm elevation
- Tongue tip cannot reach the palate and 'bowstrings' on protrusion (Correct answer)
- Patient reports difficulty with spicy foods
- Heart-shaped tongue tip visible only on protrusion
Correct answer: Tongue tip cannot reach the palate and 'bowstrings' on protrusion
A frenum that prevents palatal contact and bowstrings on protrusion indicates a significant restriction requiring frenectomy before myofunctional exercises can be effective.
Question 3: A therapist documents 'interdental lisp' in a pediatric patient during the speech evaluation. Which muscle function is MOST likely contributing to this finding?
- Inadequate velopharyngeal closure
- Forward tongue placement during sibilant production (Correct answer)
- Reduced buccinator tone
- Excessive masseter bulk
Correct answer: Forward tongue placement during sibilant production
An interdental lisp results from the tongue protruding between the teeth during /s/ and /z/ production, reflecting forward tongue positioning.
Question 4: Which assessment method provides the MOST objective measure of lip seal strength during a myofunctional evaluation?
- Patient self-report of lip fatigue
- Button pull-test with measured force gauge (Correct answer)
- Observation of lip posture at rest
- Facial photograph analysis
Correct answer: Button pull-test with measured force gauge
The button pull-test using a calibrated force gauge objectively quantifies orbicularis oris strength for pre- and post-treatment comparison.
Question 5: During treatment planning, a CMT identifies that a patient has both an atypical swallow and a digit-sucking habit. Which issue should be addressed FIRST?
- Atypical swallow pattern, as it is more complex
- Digit-sucking habit, because eliminating it reduces the reinforcing stimulus (Correct answer)
- Both simultaneously to accelerate progress
- Neither until orthodontic treatment is complete
Correct answer: Digit-sucking habit, because eliminating it reduces the reinforcing stimulus
Eliminating the digit-sucking habit removes the primary causative factor that perpetuates the tongue thrust pattern.
Question 6: Which breathing assessment finding during a CMT evaluation would MOST prompt a referral to an ENT physician?
- Slight mouth breathing during exercise
- Consistent mouth breathing at rest with nasal congestion unresponsive to allergy treatment (Correct answer)
- Occasional nasal breathing lapses during sleep
- Patient preference for mouth breathing during outdoor activities
Correct answer: Consistent mouth breathing at rest with nasal congestion unresponsive to allergy treatment
Persistent mouth breathing at rest that does not respond to medical management requires ENT evaluation to rule out structural obstruction.
Question 7: A treatment plan for an adult with myofunctional disorder should ALWAYS include:
- Orthodontic treatment as a prerequisite
- Collaboration with the patient's dentist or orthodontist to coordinate care (Correct answer)
- A minimum of 52 weekly sessions
- Referral to a psychologist for habit reversal training
Correct answer: Collaboration with the patient's dentist or orthodontist to coordinate care
Coordination with the patient's dental team is essential to align myofunctional therapy goals with any structural or orthodontic treatment.
