In short. How facial soft-tissue defects are reconstructed by matching colour, texture and aesthetic units, and why the face is judged by different rules from the rest of the body.
Key points
- Facial skin differs across the face far more than most people realise.
- The eyelid is the thinnest skin in the body; the nose is thick and sebaceous; the lip is hairless and red at the margin.
- Reconstruction must match colour, texture and contour at once.
The face is not simply skin. It is a set of distinct regions: the forehead, eyebrow, eyelid, nose, lip, cheek, chin and ear. Each has its own thickness, colour, pore pattern, hair and curve. A reconstruction that closes the defect but ignores these boundaries will look wrong even if the wound has healed perfectly. That is why facial reconstruction is organised around the idea of aesthetic units.
The problem and its anatomy
Facial defects come from skin cancer excision, trauma, burns, animal bites and the removal of congenital lesions. What matters is the size and depth of the defect, which unit or units it crosses, and what is exposed underneath, whether bone, cartilage or the free margins of eyelid, lip and nose. A defect crossing the eyelid or the lip can distort a mobile margin and cause a functional problem, not only an appearance one.
Aesthetic units and how they guide the plan
The principle is straightforward: if a defect covers much of a subunit, it is often better to reconstruct the entire subunit than to patch part of it. Scars are therefore placed at the boundaries between units, where the eye already expects a change in contour, rather than across the middle of the cheek. The surgeon then chooses tissue that matches the missing unit most closely: the forehead for the nose, the ear for the rim of the nostril, the skin behind the ear for the eyelid.
Matching colour, texture and contour
Facial skin differs across the face far more than most people realise. The eyelid is the thinnest skin in the body; the nose is thick and sebaceous; the lip is hairless and red at the margin. Reconstruction must match colour, texture and contour at once. A graft from the thigh on the nose will always look pale, shiny and flat, while a full-thickness graft from the ear on the eyelid can be almost invisible. A cheek flap restores contour but adds a scar. Matching a normal side is rarely perfect, and honest surgeons say so before the operation rather than after.
Options compared
Small defects are often closed directly, with the scar in a natural crease. Larger superficial defects may take a full-thickness skin graft, particularly on the eyelid or the temple. Local flaps bring neighbouring skin with its own blood supply and restore contour. Composite defects, or those exposing bone or cartilage, may need a regional or free flap. Each carries its own scar pattern and its own risk of distortion.
Honest limits and follow-up
No reconstruction reproduces the original face. Scars are permanent and mature over twelve to eighteen months. Grafts and flaps can fail partly, and secondary refinement such as scar revision or contour adjustment is common and is planned for rather than treated as a failure. The final assessment is made at six to twelve months, and results are never guaranteed.
Seek review promptly if
- An eyelid is pulled away from the eye, the eye will not close fully, or there is pain, redness or blurred vision.
- A graft or flap on the face turns dark, cold, dusky or black, or a dressing becomes soaked with blood.
- Fever, spreading redness or severe new pain develops, or a lip or nose margin is pulled out of shape.
Frequently asked questions
What are aesthetic units and why do they matter?
The face is divided into distinct regions, each with its own thickness, colour, pore pattern and curve. If a defect covers much of a subunit, it is often better to reconstruct the entire subunit than to patch part of it, and to place scars at the boundaries between units.
Why does the right donor site differ between the nose and the eyelid?
Because facial skin differs across the face far more than most people realise. The eyelid is the thinnest skin in the body, while the nose is thick and sebaceous. A graft from the thigh on the nose looks pale, shiny and flat; a full-thickness graft from the ear on the eyelid can be almost invisible.
Will reconstruction give me back my original face?
No. No reconstruction reproduces the original face. Scars are permanent and mature over twelve to eighteen months, grafts and flaps can fail partly, and secondary refinement such as scar revision or contour adjustment is common and planned for rather than treated as a failure. Final assessment is at six to twelve months.
Risks & Limitations
- Partial or complete failure of a graft or flap, which may need further surgery.
- Donor-site scarring, delayed healing and pain. A donor site leaves its own permanent scar.
- Infection, bleeding under a graft, or fluid collecting beneath a graft or flap.
- Contracture, and recurrence of contracture after a release procedure.
- Reconstruction is usually staged: more than one operation and months of healing are normal.
- Colour, texture and contour mismatch between reconstructed skin and the surrounding area.
- Reduced or altered sensation in grafts, flaps and donor sites.
- Scars are permanent. They mature and fade but never disappear.
- Final assessment is made at 6–12 months, and longer in growing children.
When to Seek Care
- A graft or flap that turns dark, cold, dusky, purple or black, or stops bleeding when pricked.
- A dressing soaked with blood, or bleeding that does not stop with gentle pressure.
- Fever above 38 °C, or spreading redness, warmth or discharge around a wound.
- New or severe pain, or rapid swelling under a graft or flap in the first days.
- A limb that becomes pale, cold or numb after flap surgery.
- Any change in a grafted or flap-covered area that concerns you, however minor.
