Abstract
BACKGROUND
Periorbital laceration can result in complex, permanent scars, and even lead to serious complications such as cicatricial ectropion. Early intervention with laser devices has been suggested as a novel modality to reduce scar formation. However, no consensus exists regarding the optimal treatment parameters for scar management. This study evaluated the efficacy and safety of ultrapulse fractional CO2 laser (UFCL) with different fluences and densities in preventing periorbital surgical scars.
OBJECTIVE
To assess the efficacy and safety of UFCL with different fluences and densities in the prevention of periorbital laceration scars.
METHODS
A prospective, randomized, blinded study was conducted on 90 patients with periorbital laceration scars of 2 weeks old. Four treatment sessions of UFCL were administered to each half of the scar at 4-week intervals, with halves treated with high fluences with low density versus low fluences with low-density treatment. Vancouver Scar Scale was used to assess the 2 portions of each individual scar at baseline, final treatment, and 6 months. The patient's 4-point satisfaction scale was used to evaluate the patient's satisfaction at baseline and 6 months. Safety was evaluated by registration of adverse events.
RESULTS
Eighty-two of 90 patients completed the clinical trial and follow-up. There was no significant difference in Vancouver Scar Scale and satisfaction score between different laser settings between the two groups (P > 0.05). Adverse events were minor and no long-term side effects were noted.
CONCLUSIONS
Early application of UFCL is a safe, strategy to significantly improve the final traumatic periorbital scar appearance. Objective evaluation of scars did not identify differences in scar appearance between high fluences with low density versus low fluences with low density of UFCL treatment.
