Question 3

A Z-plasty with limbs at 60-degree angles theoretically increases the length of the central limb by approximately:

Accepted Answer

75%

Answer

A 60-degree Z-plasty provides approximately 75% lengthening of the central limb and is the most commonly used angle in clinical practice.

Question 4

During parotidectomy, the facial nerve is most reliably identified at which landmark?

Accepted Answer

Tragal pointer (tragal cartilage pointer)

Answer

The tragal pointer is a reliable landmark where the main trunk of the facial nerve lies approximately 1 cm deep and inferior to the tip of the tragal cartilage.
