Injecting nasolabial fold filler training aesthetics


1. What should you assess for and treat first in nasolabial fold patients?

The answer is C, Both A and B.

When consulting with your patient you should consider both mid-face volume loss and piriform fossa treatment.

If they present with mid-face volume loss – a common concern in nasolabial fold cases – then this should be addressed first.

When specifically assessing your patient’s nasolabial folds, consider whether piriform fossa treatment may be a better option. This can negate the need to treat the nasolabial folds directly.

2. When marking up your nasolabial fold patient, ensure they are…

The answer is A, Sitting upright.

When your patient sits upright you are better able to determine the area of increased volume. This is the result of hypertrophy and caudal descent of the nasolabial fat pad. Having your patient sit upright allows you to mark up your ‘no-go zone’ more effectively.

3. Which technique offers the best results for nasolabial folds in layer 2

The answer is A, Fanning medial to the nasolabial fold.

Fanning medial to the nasolabial fold is the best injecting technique to use here because this will treat the area of concern without adding volume to the hypertrophic region of the fold.

4. Treat NLFs with a cannula where possible, using this gauge…

The answer is A, 25G.

Once you feel confident using a cannula, this is recommended to reduce the likelihood of vascular occlusion. It also provides a more comfortable experience for your patient. When treating the nasolabial folds, a 25 gauge cannula should be used. A smaller cannula – a 26G or 27G, for example – becomes sharp, just like a needle.
