Question 2

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

Accepted Answer

Neck dissection below the mandibular border

Answer

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

Question 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?

Accepted Answer

6 cm proximal and 6 cm distal

Answer

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.

Question 4

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

Accepted Answer

Peroneal communicating branch to the sural artery

Answer

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

Question 5

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

Accepted Answer

Lengthen the soft palate and reorient the levator veli palatini muscle
