Which facial nerve branch is most at risk during a rhytidectomy (facelift) when dissecting near the zygomatic arch?
Answer: Temporal branch
The temporal branch of the facial nerve crosses the zygomatic arch superficially and is highly vulnerable during facelift dissection in that region.
The retaining ligaments of the face that are true osteocutaneous ligaments include which of the following?
Answer: Zygomatic and mandibular ligaments
The zygomatic and mandibular ligaments are true osteocutaneous ligaments that attach directly from periosteum to skin, while others are musculocutaneous in nature.
In breast augmentation, the dual-plane pocket technique places the upper portion of the implant beneath which tissue layer?
Answer: Pectoralis major muscle
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.
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?
Answer: Deep inferior epigastric artery
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.
Which anatomical layer is dissected during a sub-SMAS facelift to achieve greater vector control and longer-lasting results?
Answer: Superficial musculoaponeurotic system
The SMAS (superficial musculoaponeurotic system) is elevated and repositioned in a sub-SMAS facelift, allowing more durable repositioning of the midface and lower face.
During upper blepharoplasty, damage to which structure can result in ptosis of the upper eyelid?
Answer: Levator aponeurosis
Inadvertent injury to the levator aponeurosis during upper blepharoplasty is the most common cause of post-operative eyelid ptosis.
The safe zone for liposuction of the lateral thigh (lateral femoral cutaneous region) requires awareness of which nerve to prevent persistent numbness?
Answer: Lateral femoral cutaneous nerve
The lateral femoral cutaneous nerve runs in the subcutaneous layer of the lateral thigh, and aggressive liposuction in this zone can cause meralgia paresthetica.
