Using a Zipper Device to Minimize Scarring After Excision of Facial Nevi in Pediatric Patients.

ABSTRACT

BACKGROUND: This study aims to investigate the safety and effectiveness of using a zipper device to minimize scarring after facial nevi excision in pediatric patients. METHODS: A total of 48 patients were included, with 23 in the control group and 25 in the zipper group. The zipper device was used immediately to equalize skin tension after facial nevi excision. The primary outcome was the scar width measured at 1, 3, 6, and 12 months postoperatively. The Vancouver Scar Scale (VSS) was used to assess patients' scars at postoperative 12 months as a secondary outcome. RESULTS: Two patients in the zipper group withdrew from the trial due to skin irritation. The symptom disappeared within a week after the zipper device was removed. The scar width in the zipper group was smaller than that in the control group at postoperative 1, 3, 6, and 12 months. In addition, the VSS scores for scarring also showed that patients in the zipper group had significantly better scar scores than those in the control group. At postoperative 6 months, scar morphology was essentially similar to that at post 12 months in both groups, and there was a significant positive correlation between scar morphology at the 2 time points. CONCLUSION: It is safe and effective to use this zipper device to minimize scarring after excision of facial nevi in pediatric patients, and we think it be a complementary therapeutic measure in pediatric patients after facial nevus excision.
