Background and Objective Keloids are benign lesions arising from overproduction of the extracellular matrix and abnormal collagen deposition by dermal fibroblasts. This altered wound healing typically occurs in response to dermal trauma. Keloid treatment poses a challenge due to the variable nature of treatment response, which can be affected by the size, appearance, and associated symptoms of erythema, pruritus, and pain. Recently, successful treatment of keloids has been reported using the Nd:YAG laser in conjunction with 5‐fluorouracil and intralesional corticosteroids. We present a series of patients with symptomatic keloids, who we treated with only a 1064 nm Nd:YAG laser. Study Design/Materials and Methods Eight patients of Fitzpatrick skin types I–VI presented for treatment of keloids with associated symptoms of pain. The keloids were most commonly located on the trunk, and seven patients had intralesional steroid injections prior to presentation with persistence of symptoms. Patient treatment consisted of two passes under a long‐pulsed 1064 nm Nd:YAG laser with a 10 mm spot size, a fluence of 18–19 J/cm 2 , and 60 ms pulse duration every 3–8 weeks. Patient‐reported pain scores were collected before and after treatment. Results Following treatment, transient erythema and mild edema were noted at the treatment site. All patients reported improvement in the symptoms of pain, with an average of a 5‐point reduction using a 10‐point scale (R: 2–10). Five out of eight patients had total resolution of their pain. An average of 3.25 treatments (R:1–5) were needed for patients to first notice an improvement in the pain. A Wilcoxon signed‐rank test showed that treatment with a 1064 nm laser elicited a statistically significant improvement in pain in individuals with keloids ( Z = 2.46, P = 0.01). No patients in our study suffered any scarring or pigment changes as a result of these treatments. Conclusion Keloids are a common condition with variable rates of treatment satisfaction. Lasers have been used in an attempt to improve clinical appearance and associated symptoms. We report a significant reduction in pain for patients treated exclusively with a 1064 nm Nd:YAG laser.
