Background: The objective of this study was to determine optimal treatment parameters utilizing non-ablative fractional photothermolysis for the treatment of burn scars in patients with Fitzpatrick skin types (FST) IV-V. Patients were evaluated for improvement at variable follow up intervals. Study: nine patients (4 female, 5 male), FST IV-V, with burn scarring of the face were treated with a 1550-nm fractionated Erbium-doped fiber laser. Patients underwent 4-8 treatments at a minimum of 6-8 week intervals (8 passes per treatment session) at energy fluences ranging from 60-70 mJ and treatment levels ranging from 5-8, which corresponds to surface area coverage of % (0.58-3.70 total kJ; average 2.06 kJ). All patients were started on a topical bleaching cream at their initial treatment visit and continued use in between and after laser treatments. Patients were evaluated for improvement in the clinical appearance of burn scar before each treatment and at a follow-up visit after the final treatment. Results: 100% of patients had improvement in the appearance of the burn scars. After a minimum of 4 treatments, 4 patients (44.4%) had excellent results rated by an independent dermatologist. 4 patients (44.4%) had good results as rated by an independent dermatologist. 1 patient had mild improvement as rated by an independent dermatologist. Improvement in appearance continued throughout treatment and further treatments yielded improved results in all cases. Conclusion: Our results indicate that fractional photothermolysis with the 1550-nm erbium-doped fiber laser is a safe and effective treatment option for burn deformities in patients with FST IV-V.
