Question 1

Which perforator artery is the primary basis for the DIEP flap used in breast reconstruction?

Accepted Answer

Deep inferior epigastric artery

Answer

The DIEP flap is based on perforators from the deep inferior epigastric artery, sparing the rectus abdominis muscle.

Question 2

In rhinoplasty planning, the nasofrontal angle in a female patient ideally measures approximately:

Accepted Answer

130–135°

Answer

The ideal nasofrontal angle in women is approximately 130–135°, slightly more open than the male ideal of 120–130°.

Question 3

The thoracodorsal nerve, if injured during axillary dissection, causes weakness in which muscle?

Accepted Answer

Latissimus dorsi

Answer

The thoracodorsal nerve innervates the latissimus dorsi; injury results in weakness of arm adduction and internal rotation.

Question 4

During abdominoplasty, preservation of which nerve prevents sensory loss to the lateral thigh?

Accepted Answer

Lateral femoral cutaneous nerve

Answer

The lateral femoral cutaneous nerve crosses near the ASIS and can be injured during abdominoplasty, causing meralgia paresthetica.

Question 5

Which zone of the breast, according to the Würinger ligament anatomy, provides the primary neurovascular supply to the nipple-areola complex?

Accepted Answer

Central horizontal septum zone

Answer

The Würinger septum (central horizontal septum) carries the primary neurovascular supply to the NAC and is preserved in superomedial pedicle techniques.
