Which fascial layer is incised to access the submuscular plane during transaxillary breast augmentation?
Answer: Pectoralis fascia (clavipectoral fascia)
The clavipectoral (pectoralis) fascia must be divided to access the subpectoral plane when performing transaxillary submuscular breast augmentation.
In a brow lift, which nerve must be identified and protected to avoid loss of forehead sensation?
Answer: Supraorbital and supratrochlear nerves
The supraorbital and supratrochlear nerves exit foramina at the superior orbital rim and provide sensation to the forehead; injury causes permanent forehead numbness.
The 'danger zone' in neck liposuction where the marginal mandibular nerve is most at risk corresponds to the area:
Answer: 1–2 cm below the mandibular border anteriorly near the angle
The marginal mandibular nerve dips below the mandibular border by up to 2 cm anteriorly, creating a danger zone during aggressive subplatysmal neck liposuction.
Which blood supply concept explains why periumbilical perforators are critical to preserve during full abdominoplasty?
Answer: Zone of perfusion from DIEA perforators
The periumbilical perforators from the deep inferior epigastric artery (DIEA) supply the central abdominal flap; sacrificing them risks necrosis in the watershed zone.
During a deep plane facelift, which anatomical structure separates the superficial from the deep compartments and is released to allow composite flap elevation?
Answer: Deep plane including SMAS and zygomatic retaining ligaments
The deep plane lift releases the SMAS along with the zygomatic and masseteric cutaneous ligaments, allowing the composite flap (SMAS + subcutaneous tissue + skin) to be mobilized as a unit.
In otoplasty for prominent ears, the antihelical fold is recreated primarily by modifying which cartilaginous structure?
Answer: Antihelix
Otoplasty targets the antihelix, which is either scored, abraded, or sutured (Mustardé technique) to recreate the antihelical fold and reduce ear protrusion.
When performing a medial thighplasty, which neurovascular structure in the femoral triangle must be avoided to prevent significant hemorrhage or numbness?
Answer: Saphenous nerve and great saphenous vein
The saphenous nerve and great saphenous vein course through the medial thigh and are at risk during medial thighplasty; their injury causes persistent medial leg numbness and potential DVT risk.
