The corner stitch is a common
suture technique.[1] It used to close
wounds that are angled or Y-shaped without appreciably compromising blood supply to the wound tip.[2][3]
The corner stitch is a variation of the
horizontal mattress stitch, and is sometimes called the "half-buried horizontal mattress stitch".[4] The needle enters the skin on one side of the obtuse angle of the wound, passes through the deep
dermis of the corner flap, and is re-inserted through the dermis of the other side of the obtuse wound angle. It finally re-emerges through the
epidermis on the side of the obtuse angle, adjacent to the initial entry point.[citation needed]
