(4) Debridement of necrotic tissue. Tissue that is obviously necrotic should
be excised prior to wound closure. Necrotic tissue increases the rate of wound infection
and abscess formation. This procedure should be performed by a physician or a
physician's assistant under the direct supervision of a physician.
CAUTION:
Tissue that has borderline viability should be left intact in the nose and
ear areas. There is excellent vascularity in these areas, and even the
loss of small amounts of tissue in these areas is noticeable.
