1064 nm Nd:YAG laser treatment of melanocytic nevi of the external auditory canal: a retrospective study of 15 cases

The aim of this study was to evaluate the efficacy and safety of 1064 nm neodymium-doped yttrium-aluminum-garnet laser treatment of melanocytic nevus of the external auditory canal. Retrospective chart review of 15 patients operated by 1064 nm Nd:YAG laser in single center. Data from charts and video documentation were collected and analyzed. Between November 2017 and November 2018, 15 patients underwent 1064 nm Nd:YAG laser treatment for melanocytic nevus of the external auditory canal were analyzed in the study. The size of melanocytic nevus ranged from 4 to 8 mm in diameter. A gross total removed was achieved in all cases. Two patients received two sessions of Nd:YAG laser treatments, and the remaining thirteen patients received only one session. After laser treatment, wounds healing well and the average epithelialization time was 2.3 weeks. The mean follow-up was 12 months. There were no recurrence and adverse side effects in all cases. This research supports the use of 1064 nm Nd:YAG laser as a safe and efficacious treatment for melanocytic nevus of the external auditory canal.
