  1. Which cannula tip design is preferred to minimize the risk of intravascular injection compared to sharp needles?

    Answer: Blunt-tip microcannula

    Blunt-tip microcannulas deflect off vessel walls rather than piercing them, substantially reducing the likelihood of intravascular filler placement.

  2. The recommended injection depth for treating nasolabial folds with a high-G' HA filler is typically:

    Answer: Subcutaneous

    Nasolabial folds are best addressed subcutaneously, where the filler can volumize the underlying tissue without creating a visible ridge in the skin.

  3. When performing a thread lift with PCL (polycaprolactone) threads, the primary long-term advantage over PDO threads is:

    Answer: Longer duration due to slower degradation (up to 2 years)

    PCL degrades more slowly than PDO, maintaining its structural support and collagen-stimulating effect for up to 18–24 months.

  4. Lidocaine is commonly added to HA filler preparations to:

    Answer: Reduce patient discomfort during injection

    Pre-mixed lidocaine in HA formulations provides in-situ analgesia, improving patient comfort without affecting the filler's volumizing properties.

  5. The retrograde linear threading technique involves:

    Answer: Depositing filler as the needle is withdrawn along the treatment path

    In retrograde threading, product is released during needle withdrawal, creating an even column of filler along the desired plane.

  6. Which filler material is most appropriate for periosteal placement to restore malar (cheekbone) projection?

    Answer: High-G' HA or CaHA filler

    Deep supraperiosteal placement requires a firm, high-G' product or CaHA to provide structural lift and project the malar complex effectively.

  7. Hyaluronidase dissolves HA filler by cleaving:

    Answer: Glucosaminidic bonds within the HA polysaccharide chain

    Hyaluronidase is a hydrolase enzyme that cleaves the beta-1,4 glucosaminidic bonds of the HA backbone, breaking down both native and cross-linked HA.
