Patients were randomized to have skin closure following CS with either staples or 3 different types of subcuticular sutures. Scar quality was evaluated 2 and 6 months postoperatively. The Vancouver Scar Scale, the Patient and Observer Scar Assessment Scale (POSAS), and a visual analog scale were used as scar assessment tools.
Of the 180 patients who were recruited, 123 successfully completed the study. No difference in both subjective and objective scar rating was detected across groups at either 2 months or 6 months. In the overall study population, objective scores correlated with patient rating, and correlation was strongest between the observer and patient components of the POSAS (r = 0.48).
In women undergoing CS, stapled wounds and those closed with subcuticular sutures result in equivalent cosmetic appearance of the scar.
