• interrupted and
• continuous

For satisfactory wound healing:

• the wound edge is slightly everted to avoid wound depression 
• the tissue is not constricted by suture
• the dead space is closed to reduce the risk of infection, haematoma and wound depression
• the wound edges are joined loosely since there is always some postoperative swelling.


(More information about suture techniques.)
 

• the earlier the sutures are removed the less the likelihood of persistent puncture marks but the greater the risk of dehiscence. As a approximate guide, sutures on the face should be removed after 5 days. However, those sutures at the lid margin (grey line) sutures should be left for at least 10 days to avoid the risk of dehiscence.

• the sutures should be removed by pulling it out towards the wound (as in Figure A). If the sutures were pulled out away from the wound (as in B and C), the wound may become dehiscence.
