Identify the
problem(s)
- Location
- Depth
- Size
Cartilage?
Scars?
Assess your
resources
- Tissue reservoirs
- Skin distensibility
- Tip ptosis
- Size of nose
Recognize
the dangers
- Alar retraction
- Pre-existent asymmetry
- Tip twisting
- Eyelid tethering
- Nasal obstruction

• ISSUES
• Defect depth
• Depression with FTSG
• Close to rim
• Rim retraction with wound healing, pull of
local flap
• Young patient
• limited malleability for local flap
• Less tolerance for scars
• May have future cancers
• OPTION perichondrocutaneous graft from ear
• Re-vascularizes very well
• Can place thicker graft than typical skin graft
• Resists contracture better than FTSG
• Avoids issues with local flap

AUGMENTED SKIN GRAFTING FOR EXTERNAL RESURFACING
• No vascularized
wound bed to
support skin graft
• Deep defects
• Too large for
local flap
• But no need for
structural grafting

TAKE HOME POINTS
Fill the hole:
“Augmented” skin graft techniques can be useful for resurfacing deep, devascularized or structurally weak areas
• Perichondrocutaneous
• Composite
• Delayed grafting • Integra FTSG • FTSG cartilage augmentation
Geometric rearrangements:
Design flaps based on maximal tissue reservoirs
even at expense of non-subunit scars
Know your pivot points, areas of maximal tension
