Question 1

Which facial nerve branch is most at risk during a rhytidectomy (facelift) when dissecting near the zygomatic arch?

Accepted Answer

Temporal branch

Answer

The temporal branch of the facial nerve crosses the zygomatic arch superficially and is highly vulnerable during facelift dissection in that region.

Question 2

The retaining ligaments of the face that are true osteocutaneous ligaments include which of the following?

Accepted Answer

Zygomatic and mandibular ligaments

Answer

The zygomatic and mandibular ligaments are true osteocutaneous ligaments that attach directly from periosteum to skin, while others are musculocutaneous in nature.

Question 3

In breast augmentation, the dual-plane pocket technique places the upper portion of the implant beneath which tissue layer?

Accepted Answer

Pectoralis major muscle

Answer

In dual-plane augmentation, the upper implant lies under the pectoralis major while the lower portion is in the subglandular space, optimizing coverage and shape.

Question 4

The sentinel node in abdominoplasty refers to a perforator vessel that, if injured, may lead to flap necrosis. It typically arises from which source vessel?

Accepted Answer

Deep inferior epigastric artery

Answer

The sentinel or 'danger' perforator in abdominoplasty arises from the deep inferior epigastric artery and is critical to the vascular supply of the abdominal flap.

Question 5

Which anatomical layer is dissected during a sub-SMAS facelift to achieve greater vector control and longer-lasting results?

Accepted Answer

Superficial musculoaponeurotic system

Answer

The SMAS (superficial musculoaponeurotic system) is elevated and repositioned in a sub-SMAS facelift, allowing more durable repositioning of the midface and lower face.
