Which blood vessel is at highest risk of occlusion during glabellar filler injections?
Answer: Supratrochlear artery
The supratrochlear artery runs through the glabella and its occlusion can cause skin necrosis or retrograde embolization to the ophthalmic artery.
The orbicularis oris muscle is responsible for:
Answer: Puckering and compressing the lips
The orbicularis oris encircles the mouth and controls lip movements including puckering, pursing, and closure.
Bone resorption with aging affects facial aesthetics primarily by:
Answer: Reducing skeletal support and contributing to soft-tissue descent
Age-related bone resorption reduces the bony scaffold of the face, causing overlying soft tissue to descend and volume to redistribute.
What is the primary role of hyaluronic acid in the skin?
Answer: Retaining water to maintain skin hydration and volume
Hyaluronic acid is a glycosaminoglycan that binds water molecules, keeping the dermis hydrated, plump, and resilient.
The zygomatic arch forms part of which broader facial region relevant to cheek augmentation?
Answer: Midface/malar region
The zygomatic arch and malar eminence define the midface/malar region, which is the primary target zone for cheek volumization.
Which layer of the scalp is considered the 'dangerous layer' due to emissary veins connecting it to intracranial sinuses?
Answer: Loose connective tissue
The loose connective tissue layer of the scalp contains emissary veins, allowing infections to spread intracranially.
