The paramedian forehead flap used for reconstruction of large nasal defects is based on which arterial pedicle?
- A Supratrochlear artery ✓
- B Superficial temporal artery
- C Angular artery
- D Infraorbital artery
Correct answer: A. Supratrochlear artery
Explanation
The paramedian forehead flap is an axial pattern flap supplied by the supratrochlear artery, which emerges above the eyebrow just medial to the supraorbital notch. Its colour and texture make it the workhorse for resurfacing large nasal defects. The angular artery supplies the nasolabial (melolabial) flap used for smaller alar and cheek defects, while the superficial temporal artery feeds temporoparietal fascia flaps.
