On the whole, spontaneous granulation or laissez-faire
is not recommended except for very small wound.
the excision margins are not distorted and therefore
useful in confirming complete excision of a malignant tumours such as malignant
melanaoma or sebaceous cell carcinoma (in which frozen section and Mohs'
technique have limitation in confirming complete excision)
Spontaneous granulation is most useful in the medial canthal
region. This is because in this region, contraction occurs in a centripetal
direction and tension is distributed at the wound perimeter. The result
is less distortion of the lid and the surrounding structure.
increased contracture of the scar
increased distortion of the surrounding tissue
