Abstract

PURPOSE
Facial scars are a main complaint of patients who had undergone suture in the emergency department. Therefore, effective techniques for minimizing scar formation are required. W-plasty, a widely used method of scar correction, has been performed to change the scar direction or divide it into multiple segmented scars. This method can be applied in the initial stage of wound repair in the emergency department. The aim of this study was to investigate the effectiveness of direct application of W-plasty to the wound in simultaneously accomplishing the aforementioned objectives.
METHODS
This was a prospective study, from June 2012 to June 2014. Either simple debridement or W-plasty for facial laceration was performed in 31 patients. In patients in the simple debridement group, the excision was made along the laceration margin. In patients in the W-plasty group, the excision was made within the W-form predesigned margin of the laceration. The prognosis was evaluated using the Stony Brook scar evaluation scale (SBSES).
RESULTS
Among 31 patients, 15 underwent simple debridement and 16 underwent W-plasty. In procedure time, there was no significant difference between the two groups. No complications were observed in either group. The median SBSES score was 4 (IQR, 3-4) in the simple debridement group and 5 (IQR, 5-5) in the W-plasty group, indicating a significant difference between the two groups (p<0.001).
CONCLUSION
We achieved good results of direct W-plasty application to wound lacerations in terms of minimal scar formation. Thus, for patients with facial lacerations, we suggest that application of W-plasty to the wound debridement is more effective than the classic simple debridement.
