Question 2

What is the primary goal of the SMAS plication technique in facelift surgery?

Accepted Answer

Reposition the superficial musculoaponeurotic system without incising it

Answer

SMAS plication folds and sutures the SMAS to itself, elevating it without making an incision through it.

Question 3

In upper blepharoplasty, which anatomic layer must be preserved to prevent lagophthalmos?

Accepted Answer

Orbicularis oculi muscle

Answer

Excessive removal of orbicularis oculi muscle impairs eyelid closure, leading to lagophthalmos and corneal exposure.

Question 4

A patient develops an asymmetric smile with inability to show the lower teeth on one side following a facelift. Which structure was likely injured?

Accepted Answer

Marginal mandibular branch of the facial nerve

Answer

The marginal mandibular branch innervates the depressor anguli oris and depressor labii inferioris, and its injury causes inability to depress the lower lip.

Autologous rib cartilage provides durable augmentation with the lowest rates of infection and extrusion compared to alloplastic materials.
