Spontaneous granulation

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)


  • delayed healing
  • increased contracture of the scar
  • increased distortion of the surrounding tissue
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.
