  1. Which perforator flap is based on perforators from the profunda femoris artery and is used for breast reconstruction?

    Answer: PAP flap

    The profunda artery perforator (PAP) flap is harvested from the posterior thigh and based on perforators from the profunda femoris artery.

  2. The marginal mandibular branch of the facial nerve is most vulnerable during which reconstructive procedure?

    Answer: Neck dissection below the mandibular border

    The marginal mandibular branch, which has limited redundancy, is at greatest risk during dissection below the lower border of the mandible during neck dissection.

  3. During a fibula free flap harvest, what is the minimum segment of fibula that must be preserved proximally and distally to protect joint stability?

    Answer: 6 cm proximal and 6 cm distal

    At least 6 cm of fibula must be preserved proximally to protect the peroneal nerve and knee, and 6 cm distally to maintain ankle stability.

  4. The reverse sural artery flap is perfused in retrograde fashion via which anastomotic connection?

    Answer: Peroneal communicating branch to the sural artery

    The reverse sural flap relies on the peroneal communicating branch connecting the peroneal artery to the sural artery for retrograde perfusion.

  5. In cleft palate repair using the Furlow double-opposing Z-plasty, the primary goal of the technique is to:

    Answer: Lengthen the soft palate and reorient the levator veli palatini muscle

    The Furlow Z-plasty lengthens the soft palate and repositions the levator veli palatini muscle into its correct transverse orientation to improve velopharyngeal function.

  6. The Allen test assesses patency of which two arteries before radial forearm flap harvest?

    Answer: Radial and ulnar arteries

    The Allen test evaluates the patency of both the radial and ulnar arteries to ensure adequate hand perfusion from the ulnar side after radial artery sacrifice.

  7. Which layer of the scalp contains the neurovascular supply to the overlying skin?

    Answer: Dense connective tissue layer

    The dense connective tissue layer (second layer of SCALP) contains the blood vessels, lymphatics, and nerves supplying the scalp skin.
