Corner stitch

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.
