A figure-of-8 suture crosses the wound or extraction socket in an “X” pattern, with the strands looped around the tissue edges and tied on the opposite side; this distinctive crossing appearance differentiates it from simple loops and from horizontal or vertical mattress configurations. Clinical descriptions of extraction-site closure specifically refer to placing a “figure of eight suture” in this manner [Girish Kumar et al., 2018, PMID 29411166].
