Question 1

Which hyaluronic acid filler property is most associated with resistance to deformation under pressure?

Accepted Answer

Cohesivity

Answer

Cohesivity refers to the cross-linked gel's ability to maintain shape and resist fragmentation under mechanical stress.

Question 2

Calcium hydroxylapatite (CaHA) fillers differ from hyaluronic acid fillers primarily because they:

Accepted Answer

Stimulate neocollagenesis over time

Answer

CaHA microspheres act as a scaffold that stimulates fibroblasts to produce new collagen, providing biostimulatory effects beyond initial volume.

Question 3

When reconstituting botulinum toxin type A, which diluent is universally recommended?

Accepted Answer

Bacteriostatic normal saline

Answer

Bacteriostatic normal saline (0.9% NaCl with benzyl alcohol) is preferred because benzyl alcohol provides mild anesthesia and preserves the toxin.

Question 4

The 'fern pattern' technique in thread lifting refers to:

Accepted Answer

Placement of barbed threads in a branching configuration

Answer

The fern pattern describes deploying barbed threads in diverging directions from a single entry point to maximize tissue lifting coverage.

Question 5

Which characteristic distinguishes a biphasic HA filler from a monophasic one?

Accepted Answer

Biphasic fillers contain two cross-linked HA phases mixed together

Answer

Biphasic fillers consist of distinct cross-linked HA particles suspended in a non-cross-linked HA carrier gel, giving different lift and spreadability properties.
