Case Series of Fractional Ablative Laser Resurfacing of Pediatric Facial Traumatic and Surgical Scars.

[BACKGROUND AND OBJECTIVES] Fractional ablative 10,600-nm carbon dioxide (CO ) laser has well-demonstrated safety and efficacy in resurfacing treatment of scars in the adult population and in the treatment of pediatric burn scars. However, there is a paucity of literature regarding laser resurfacing of traumatic and surgical scars for cosmetic benefit in the pediatric population, and in majority of cases previously reported, this was done under general anesthesia.

[STUDY DESIGN/MATERIALS AND METHODS] This was a retrospective chart review of pediatric patients under the age of 18 who underwent fractional ablative CO laser resurfacing (FALR) of traumatic or surgical scars at a single center between 2018 and 2019, inclusive. Primary endpoints included safety and tolerance.

[RESULTS] A total of 31 FALR treatments were performed in 10 patients with traumatic and surgical scars located on the face (age 4-14 years, Fitzpatrick skin type [FST] I-IV, 60% female). Settings ranged from total energy per session 0.02-0.33 kJ, with a 7-mm tip and 30-50% coverage. Nine patients had two or more treatments (average 3, maximum 8) spaced at least 4 weeks apart. All resurfacing treatments were well-tolerated with local infiltration of 1% lidocaine with epinephrine (1:100,000). Six (67%) patients were treated with additional measures including pulsed dye laser, 1927-nm fractional non-ablative low-energy, low-density laser, or intralesional agents (5-fluorouracil, triamcinolone, botulinum toxin). At follow-up (of varied intervals), short-term erythema, as expected, was seen in six patients, and hyperpigmentation in one case (FST IV), both treated with aforementioned alternate devices. Although gradual, improvement in scar appearance and texture was seen with FALR treatments. No additional scarring, infection, or hypopigmentation was seen.

[CONCLUSIONS] Treatment with fractional ablative laser resurfacing is safe and well-tolerated in the pediatric population in an outpatient setting with local anesthesia. Traumatic scars may cause significant distress to children and parents alike. Multimodal therapy may lead to optimal cosmesis. Given the excellent tolerability, the authors recommend consideration of laser resurfacing in pediatric patients with traumatic or surgical scars when bothersome, either cosmetically or psychologically.
