BackgroundNevus of Ota (NO) is a relatively common pigmentary disorder in Asians. Tanino's classification is an old but tacit consensus to delineate the disease. Various treatment options have been presented. However, a few studies have been conducted on available laser options and current treatment strategies or the classification of NO.ObjectiveTo investigate current laser options and their effectiveness for the treatment of NO, contributing factors to clinical outcomes, and verification of classification.MethodsA retrospective study of NO was conducted by reviewing medical charts and photographs of sixty-seven patients. Statistical analysis was used to compare excellent and poor outcomes and determine contributing factors.ResultsThe median age of onset was below the age of 1 (interquartile range [IQR], 0~1). Tanino's and PUMCH classification systems failed to classify patients in 24 (35.8%) and 6 (9.0%) of patients, respectively. A 1,064 nm Q-switched Nd:YAG laser without additional lasers was used most frequently in 42 patients (62.7%). The frequency of treatment was 19.0 (IQR, 10.0~23.0) in the cured group defined as subjects showing 95% improvement or above, compared to 10.0 (IQR, 6.25~13.75) in the unattained group defined as subjects showing less than 95% improvement (p=0.001).ConclusionA 1,064 nm Q-switched Nd:YAG laser is a reliable treatment armamentarium, functioning as a single infallible modality as well as a combination treatment modality for NO. Repetitive laser treatments without interruption seems to be the most suitable in clearing NO. The current classification systems of NO are defective. Thus, a new classification should be developed.

Nevus of Ota is a benign hamartoma which presenting as blue-gray hyperpigmented patches on the face and mucous membranes usually within the distribution of first and second branches of the trigeminal nerve. It may occur at birth or during adolescence and the nevus of Ota is very common seen in Japan and east countries. The pigmentation varies and can be dark brown to blue to black-blue. We report a 31-year-old female patient with the nevus of Ota. The Q-switched Nd: YAG laser, had a spot size of 3 mm, an 8 Hz repetition rate, 720 mj/cm 2 fluence. The patient's lesion improved in a rate of 60% with a single session. The Q-switched Nd: YAG laser has a significant effect in treating the nevus of Ota.

Background: Naevus of Ota, also called naevus fusculocoeruleus ophtalmomaxillaris, belongs to the group of dermal melanocytoses. It typically occurs in the Asian population, and it is extremely rare in Caucasians. The management of naevus of Ota has been challenging. Observation: We report a Caucasian patient presenting with a bilateral naevus of Ota which was successfully treated using a Q-Switched (QS) Nd: YAG 1064 laser. We further review the various available therapeutic options as well as the results obtained with various laser types, including the QS Nd: YAG 1064 and 532 nm, the QS ruby 694 nm and the QS alexandrite 755 nm lasers. Conclusion: Based on the remarkable clinical improvement observed in our case and previous reports, Q-Switched lasers currently represent the treatment of choice for the naevus of Ota. Development of picosecond techno logy in laser medicine has opened a new perspective for the treatment of Ota.
