Introduction: An excessive proliferation of fibroblasts and collagen synthesis after an injury may lead to a benign fibrous tumor, known as keloid, which does not regress spontaneously. Earlobes are a very frequent site of onset, since after a trauma (i.e., piercing) keloids may develop either on the helix and on the anterior or posterior lobe, from a few months up to several years after the injury.
Objectives: To report the effectiveness of a combined protocol of CO2 laser + Dye laser + a portable Blue LED Light medical device for Photobiomodulation Therapy (EmoLED®).
Methods: Fifty-two patients with a total of 56 ear keloids have been treated in the same session with a single CO2 laser procedure + a pulsed Dye laser procedure with an adjunctive EmoLED® procedure for 3 up to 6 min. A monthly follow-up has been performed with an adjunctive EmoLED® session in case of signs of inflammation.
Results: Among 56 treated keloids, 89.3% of them (50/56) did not recur during a follow-up period (from 6 up to 24 months, mean 16.3 months) while six keloids recurred (6/56, 10.7%) with mild thickening of the scar, thus requiring further treatments.
Conclusions: Even if an excellent outcome obtained by the synergistic effect of combined laser treatments has already been described (i.e., CO2 laser + Dye Laser), the present study showed the adjuvant procedure with EmoLED® can reduce significantly the risk of keloids recurrences.
