C. Inject into the mid-dermis at the temporal fat pad

Avoid all injections at the temple entirely

Q3. Which facial artery carries the HIGHEST risk of causing filler-induced blindness due to its direct connection to the ophthalmic artery?(Required)

A. Facial artery

B. Supraorbital artery

C. Angular artery

D. Mental artery

Q4. The corrugator supercilii injection depth changes along its length. Which statement is correct?(Required)

A. Superficial medially, deep laterally

B. Deep medially (bone attachment), superficial laterally

C. Same depth throughout -- inject uniformly

D. Only inject at the medial head where it is thickest

Q5. All three major neurovascular foramina (supraorbital, infraorbital, mental) align along which vertical line?(Required)

A. Lateral canthus line

B. Mid-nasal line

C. Mid-pupil vertical line

D. Medial canthus line

Q6. Which CN VII branch has NO redundancy, meaning injury causes permanent facial deficit?(Required)

A. Temporal branch

B. Zygomatic branch

C. Buccal branch

D. Marginal mandibular branch

Q7. For safe lip filler injection, what is the maximum recommended depth?(Required)

A. 1 mm -- purely intradermal

B. 3 mm -- labial arteries lie within/below orbicularis oris

C. 5 mm -- deep submucosal plane

D. 8 mm -- supraperiosteal at the oral sulcus

Q8. The Triangle of Youth concept describes which facial shape change with aging?(Required)

A. Face shifts from square base to narrower forehead

B. Face shifts from inverted triangle (cheek-wide) to upright triangle (jaw-wide)

C. The nasal triangle widens as nose droops

D. Orbital volume increases creating a triangular shadow

Q9. Which injection plane is SAFEST for deep cheek and temple volumization?(Required)

A. Intradermal

B. Subcutaneous

C. Sub-SMAS

D. Supraperiosteal

Q10. What makes the glabella the HIGHEST risk zone for filler?(Required)

A. Skin is thickest here preventing proper distribution

B. Supratrochlear and angular arteries anastomose with the ophthalmic artery

C. The corrugator prevents needle placement

D. The frontalis obscures the injection endpoint

Q11. Which nerve is the primary MOTOR nerve of facial expression?(Required)

A. CN V (Trigeminal)

B. CN VII (Facial nerve)

C. CN III (Oculomotor)

D. CN XI (Accessory)

Q12. Orbicularis oculi crow's feet injections must be placed at which depth to avoid lagophthalmos?(Required)

A. Deep intramuscular at the orbital rim

B. Subdermal only -- lateral to the orbital rim

C. Supraperiosteal beneath the muscle belly

D. Sub-SMAS below the orbital septum

Q13. What is the primary clinical role of the DEEP fat compartments of the face?(Required)

A. They provide superficial contour and skin support

B. They provide foundational structural support -- their loss collapses the midface scaffold

C. They are the target for all neurotoxin injections

D. They are unaffected by the aging process

Q14. Which muscle causes cobblestone chin and is treated with deep midline neurotoxin injections?(Required)

A. Depressor anguli oris

B. Orbicularis oris

C. Mentalis

D. Depressor labii inferioris

Q15. A patient reports sudden visual changes after NLF filler injection. What is the FIRST action?(Required)

A. Apply ice and monitor for 15 minutes

B. Stop immediately, inject hyaluronidase at site and along vascular pathway, call emergency ophthalmology

C. Continue -- this is normal transient pressure

D. Aspirate and reposition the needle

Q16. Which technique is preferred for NLF filler to reduce vascular occlusion risk?(Required)

A. Sharp needle bolus injection

B. Blunt cannula with retrograde threading

C. Multiple sharp needle serial puncture superficially

D. Push-ahead with 25G sharp needle

Q17. DAO injection must be placed in what anatomical relationship to the mandibular ligament?(Required)

A. Lateral to the mandibular ligament

B. Medial and superficially to the mandibular ligament

C. Deep along the mandibular border

D. At the modiolus 2 cm lateral to the commissure

Q18. The facial venous system is valveless. What is the primary clinical danger?(Required)

A. Veins collapse easily causing bruising

B. Retrograde flow allows infection to spread intracranially via the cavernous sinus

C. Venous pressure prevents adequate filler placement

D. Blood return during aspiration is unreliable

Q19. What is the correct emergency hyaluronidase dose for suspected vascular occlusion?(Required)

A. 10 units at the entry point only

B. 150-300+ units at site and along vascular pathway, repeated every 30 min

C. 1 unit per 0.1 mL of filler placed

D. Apply topically only -- never inject

Q20. For cheek volumization, which anatomical plane provides the safest most predictable result?(Required)

A. Subcutaneous plane over the zygoma

B. Sub-SMAS beneath the zygomaticus major

C. Supraperiosteal along the zygomatic arch and cheek bone

D. Intradermal at the malar eminence
