Blue Light in the treatment of ear keloids
An innovative combined protocol of CO2 laser + Dye laser + Blue LED Light Photobiomodulation have been tested as treatment for ear keloids by Skin Center dermatological services (L’Aquila, Avezzano, Pescara e Catania). 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 and can be disfiguring. 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. Keloids have a high tendency to recur following surgical excision (45% up to 100%), thus leading to the need of new treatments. Among the past decades, many treatments have been proposed to approach keloids, with different degrees of reported success and different percentages of recurrences but a gold standard treatment for keloids is yet to be discovered. In Authors’ experience, the combined three-steps protocol of CO2 laser + Dye laser + Blue LED Light Photobiomodulation (EmoLED) led to only a 10.7% of keloid recurrence, which is to be considered a significant result in this field.
