Which statement best describes the half-buried mattress stitch?

• A. Used for triangular flaps
• B. Used for subcuticular closures
• C. Used for vertical closures in linear wounds
• D. Used to relieve edema

Answer: (A)

When closing skin flaps, you want a pattern that securely anchors tissue while keeping the knot out of the way and ensuring the edges remain everted for a smooth contour. The half-buried mattress stitch achieves this by taking a deep bite on one side and a more superficial bite on the other, then tying with the knot buried under the tissue. This arrangement provides strong wound-edge apposition and minimizes visible knots, which is especially useful for triangular flaps where the flap base is narrow and edge control is important. That combination—secure anchoring of a triangular flap with a buried knot—is why this stitch is described as being used for triangular flaps. Subcuticular closures rely on stitches entirely within the dermis with no external knots, so they aren’t the same pattern. Vertical closures in linear wounds are typically addressed with vertical mattress techniques to capture deeper tissue along a straight line. Edema relief isn’t achieved by a suture pattern; it’s managed by factors like drainage and compression.
