    Abstract:
    Purse-string suture (PSS) and full-thickness skin graft (FTSG) are two different approaches to the closure of circular skin defects. In this study, we compare the feasibility and the aesthetic outcome of these two techniques in high operatory risk non-melanoma skin cancer (NMSC) patients. We performed a retrospective study on 65 patients, treated with PSS or FTSG, and evaluated after a minimum follow-up of 6 months. The post-surgery assessment was based on the Vancouver scar scale (VSS) and differences in terms of defect areas, operative and healing times were performed both with parametric and nonparametric tests. Operative times in PSS were significantly lower than those needed for FTSG, without perioperative adverse events; PSS required a waiting time before removing the suture greater than FTSG. After surgery, PSS resulted in a median defect area reduction of 73%. No significant differences were found in the median value for VSS in the two groups. Based on our clinical experience, the PSS advantages in terms of feasibility, rapidity of execution, and mean defect area reduction were confirmed. So, this technique seems to be appropriate for fragile patients affected by NMSC, that cannot hold long surgical sessions.
