The Modified Buried Vertical Mattress Suture

background . Recent modifications of mattress suturing techniques have been reported producing rapid and effective skin eversion and excellent tensile strength while producing cosmetically elegant results. objective . Presented here is a new modification of the buried vertical mattress suture. Results employing this technique compared with conventional bi‐layered wound closure are presented. methods . One hundred patients were analyzed in a doubleblind randomized study where excision was carried out on benign pigmented lesions of the upper back. Fifty patients were treated by a conventional bi‐layered closure technique while another 50 patients were treated by the newly described buried vertical mattress suture technique. Parameters of infection, hypertrophic scar/keloid formation, dehiscence, suture reaction, wound spread, and patient satisfaction were examined. results . The modified buried vertical mattress suture technique produced less hypertrophic scar/keloid formation (2% vs 16%) as well as less wound scar spread (6% vs 24%) compared with conventional bi‐layered suturing techniques. In addition, it was associated with a high degree of patient satisfaction (96%). conclusion . The modified buried dermal mattress suture technique produces excellent cosmetic results in closing elliptical excisions on thick dermal cutaneous anatomic areas under considerable wound tension. Its decreased requirement for postoperative wound care makes it an excellent alternative for patients living long distances from physician referral centers.
