简要总结
The purpose of this study is to determine whether the use of running subcuticular suture versus running horizontal mattress suture for the repair of cutaneous linear wounds on the trunk and extremities affects aesthetic outcomes. The study team will use a split wound model, where half of the wound is repaired with running subcuticular sutures and the other half is repaired with running horizontal mattress sutures. Three-months post-surgery, the scar will be evaluated via the patient observer scar assessment scale (POSAS), a validated scar instrument, as well as the trace-to-tape method, an objective outcome measure for linear postoperative scars. Any adverse events will also be recorded.
详细描述
Sutures are the standard of care in repairing cutaneous wounds. The majority of surgical reconstructions following a Mohs micrographic surgery and standard surgical excisions require two layers of sutures: a deep (subcutaneous) layer and a superficial (cuticular) layer. Given the overall lack of evidence in the literature, the choice of suturing technique is largely dependent on the surgeon's preference.
This study aims to investigate whether the use of running subcuticular sutures, when compared to running horizontal mattress sutures, affects wound cosmesis on the trunk and extremities.
Both running subcuticular and horizontal mattress suture techniques have been favored by surgeons for differing reasons. With running subcuticular suture, epidermal puncture points are minimized. Thus, suture may be left in place for longer periods of time leading to improved wound healing and less risk of suture-track scars. A previous study by Alam et al found that running subcuticular suture had improved appearance as compared to running cuticular suture. In contrast, the horizontal mattress suture is useful to redistribution wound tension and evert wound edges, which is felt to improve aesthetic surgical outcomes as well. Moody et al showed that when compared to running cuticular suture, a running horizontal mattress suture led to a smoother and flatter scar.
However, while there have been studies comparing and finding superiority of both the subcuticular running suture and running horizontal mattress suture compared to the running cuticular suture, these two techniques (namely, subcuticular running and running horizontal mattress) have not been directly compared to each other. We hope that our study will provide new insight into this aspect of cutaneous surgery.
This is a single center, randomized, evaluator blind, split wound study.

结局指标
主要结局
Scar Assessment as measured by Patient Observer Scar Assessment Score (POSAS)
时间窗: 3 months
The primary endpoint will be the score of two blinded reviewers independently using the POSAS assessment. The observer scale of the POSAS consists of six items (vascularity, pigmentation, thickness, relief, pliability, and surface area). All items are scored on a scale ranging from 1 ("like normal skin") to 10 ("worst scar imaginable"). The sum of the six items results in a total score of the POSAS observer scale. Furthermore, an overall opinion is scored on a scale ranging from 1 to 10. All parameters should preferably be compared to normal skin on a comparable anatomic location.
Width of Scar as measured using Trace-to-Tape Method
时间窗: 3 months
The trace-to-tape method is an objective measure for linear postoperative scars. The mean scar width will be determined using the trace-to-tape method. The surface area of the scar will be collected by tracing the scar with a water-based gel pen. While still wet, the gel residue will be lifted from the skin with clear packing tape and transferred on a sheet of paper.
