Question 1

Which aesthetic proportion ratio, classically attributed to the golden ratio, is frequently referenced in rhinoplasty planning?

Accepted Answer

1:1.618 (phi)

Answer

The golden ratio (phi ≈ 1.618) is referenced in facial aesthetic analysis including ideal nasal proportions and facial width-to-height relationships.

Question 2

In lower extremity reconstruction, the Godina principle recommends free flap coverage of open tibial fractures within:

Accepted Answer

72 hours of injury

Answer

Godina's landmark study showed free flap coverage within 72 hours significantly reduces infection rates and improves flap success compared to delayed coverage.

Question 3

The medial sural artery perforator (MSAP) flap is harvested from which anatomical region?

Accepted Answer

The medial calf from the medial head of the gastrocnemius

Answer

The MSAP flap is harvested from the skin overlying the medial head of the gastrocnemius, supplied by perforators of the medial sural artery.

Question 4

In pediatric craniofacial surgery, craniosynostosis involving the sagittal suture characteristically produces which skull deformity?

Accepted Answer

Scaphocephaly (long, narrow skull)

Answer

Premature fusion of the sagittal suture restricts lateral growth, causing compensatory anterior-posterior elongation and a scaphocephalic (boat-shaped) skull.

Question 5

Zone II flexor tendon injuries in the hand are considered surgically challenging primarily because:

Accepted Answer

Both FDS and FDP tendons share a tight fibro-osseous sheath with limited space

Answer

In zone II ('no man's land'), both flexor tendons lie within a confined fibro-osseous sheath, making repair and postoperative gliding technically demanding.
