Simple interrupted suture

David Salim med. stud., Christoffer Bing Madsen med. stud., Magnus Avnstorp MD


Epidermal approximation. Can be used alone or used as a secondary layer to aid the approximation after closing dermis/other deep sutures

Suture material choice

Thinnest as possible to minimize risk of track marks/foreign body reactions. Though consider always anatomical position of wound site 6-0 monofilament: Face/eyelids 4.0 – 5.0 monofilament: in case of moderate tension 3.0 monofilament: high tension areas

Step by step guide

1) The needle is inserted perpendicular to the epidermis
2) Rotate needle through dermis so the needle tip exits the skin on the contralateral side
3) Grasp needle body (not tip!) with forceps and pull upward
4) Release needle body from driver
5) Tie off gently and aim to minimize tension
