1 Introduction top

Nose Reconstruction by Dr. Frederick J Menick enlarge

Pre or post auricular skin grafts can be applied in the thin skin zones of the nose (dorsum, side wall or columella).

A full thickness forehead skin graft should be used in the thicker skin zones of the tip and ala.

It is often useful to delay application of a skin graft, regardless of site, for 10 days to allow initial granulation of the defect to improve skin graft neo-vascularization.


Principles of reconstruction

Skin grafts are unpredictable in color and texture due to the temporary ischemia required before skin graft “take”.  But unlike flaps, they do not pincushion or rise above the surface of adjacent normal skin after healing.

The Subunit Principle is not applied to superficial defects which are resurfaced with skin grafts.


Anaesthesia

Smaller defect can be repaired under local anesthesia with or without sedation or general anesthesia.

2 Resection top

If an initial excision is required to treat skin cancer, the tumor is excised utilizing standard excisional margins, verified by frozen section by the operating surgeon or by the Mohs technique.

Flap design

A template or pattern of the area marked for excision or the defect is outlined.


Nose Reconstruction by Dr. Frederick J Menick enlarge

The template is positioned either in front or back of the ear, or under the forehead hairline and the skin graft marked with ink. Additional "dog ears" are also outlined.

The skin is incised and the flap is harvested with the underlying subcutaneous fat to provide sufficient bulk to restore contour.

Closure of donor defect

The “dog ears” are excised.

The skin surrounding the defect is minimally undermined.

The forehead defect is closed in layers

Reconstruction

A clean surgical wound is prepared by excision of the wound edges and debridement of any injured tissues or granulation tissues.


Nose Reconstruction by Dr. Frederick J Menick enlarge

The skin graft is fixed to the defect with fine quilting sutures and a single layer of skin sutures.


Nose Reconstruction by Dr. Frederick J Menick enlarge

The area is covered with a non-adherent dressing and foam bolster, which is sutured in place. The dressing and sutures are removed after one week.
