Questions and Answers

What is the first step in the procedure for examining the masseter muscle?

Observe the patient for any involuntary movements.
Ask the patient to clench the teeth firmly together. (correct)
Apply pressure on the external surface of the jaw.
Run the examining finger along the posterior border of the masseter.

What symptom is expected when the examining finger reaches the zygomatic origin of the masseter muscle?

Numbness in the lower jaw area.
Tenderness indicated by the patient's reaction. (correct)
No reaction from the patient.
Increased muscle strength.

Why is counter pressure exerted from the external surface during the examination?

To enhance the visibility of the muscle contraction.
To prevent the patient from moving their jaw.
To properly locate the anterior border of the masseter. (correct)
To make the test less painful for the patient.

Study Notes

Masseter Muscle Tenderness Assessment

Assess masseter muscle tenderness by palpating the anterior border intra-orally.
Patient clenches teeth.
Examiner’s finger runs along masseter’s anterior border, applying counter-pressure externally.
Tenderness increases as the zygomatic origin of masseter is reached. Patient's reaction indicates tenderness.
This test helps diagnose myofascial pain dysfunction syndrome.
Repeat on the opposite side.
