“…The efficacy of alexandrite QS laser to treat Ota naevus was reported in 1992, soon followed by numerous publications reporting efficacy of other QS lasers, i.e. Nd:Yag and ruby laser . Today, the 1064 nm Nd:Yag laser appears as the most efficient comparing the balance between efficacy and side‐effects.…”

“…Nd:Yag and ruby laser. 70,76,[83][84][85][86] Today, the 1064 nm Nd: Yag laser appears as the most efficient comparing the balance between efficacy and side-effects. Due to the deflection to near infra-red of the 1064 nm band emission in the melanin light absorption spectrum, the less absorption by the epidermal melanin layer minimizes the risk of hypochromia, especially in three-five skin type phototype patients.…”

“…Due to the deflection to near infra-red of the 1064 nm band emission in the melanin light absorption spectrum, the less absorption by the epidermal melanin layer minimizes the risk of hypochromia, especially in three-five skin type phototype patients. 86 Moreover, the 1064 nm wavelength is the more penetrating among the whole range of QS lasers ( Table 2). Due to the high levelled energy ranges used, and the facial location of the lesions, treatment of Ota naevus by QS lasers is painful and topical anaesthesia is required.…”

Background Lasers and intense pulsed light sources (IPLS) are proposed for the treatment of many pigmentary disorders. They are sometimes considered as magic tools able to remove any type of lesions. Although being the best option for several hyperpigmented lesions, they can also worsen some conditions and have potential side‐effects. Objective The aim of this review was to give evidence‐based recommendations for the use of lasers and IPLS in the treatment of hyperpigmented lesions. Methods These recommendations were produced for the European Society of Laser Dermatology by a consensus panel made up of experts in the field of pigment laser surgery. Recommendations on the use of lasers and light treatments were made based on the quality of evidence for efficacy, safety, tolerability, cosmetic outcome, patient satisfaction/preference and, where appropriate, on the experts' opinion. Results Lasers and IPLS are very effective for treating many hyperpigmented lesions such as lentigos, dermal hypermelanocytosis or heavy metal depositions. In the other hand, they have to be considered with great caution for other disorders, such as café au lait macules, melasma or postinflammatory hyperpigmentation. After making the correct diagnosis, if lasers or IPLS are indicated, the optimal wavelengths and parameters will be chosen taking into account the skin phototype, origin and depth of the target pigments. Conclusion Although potentially very effective, lasers and IPLS cannot be proposed for all types of hyperpigmented lesions. In all cases, precise recognition of the disorder is mandatory for choosing between these devices and other therapeutic approaches.

Background:Q-switched neodymium-yttrium aluminium-garnet (Q switched Nd-Yag) laser has been used in the treatment of nevus of Ota in all skin types with variable success rate. Data with an objective assessment parameter to this laser treatment is lacking.Objective:To evaluate the utility of melanin index in assessing the treatment response and also determine the efficacy and safety of the Q-switched Nd-Yag laser (1064-nm) in the treatment of nevus of Ota in Fitzpatrick skin types IV and V.Materials and Methods:A total of 35 patients treated with Nd-Yag laser were studied. The objective improvement (pigment clearance) was determined by melanin index from two fixed points: A1, 2 cm below the pupil at the mid pupillary line (when the gaze is fixed); A2, the most prominent part of zygoma. The melanin index in these two areas was recorded as M1 and M2, respectively. The subjective clinical improvement was determined by the physician and the patient global assessment score.Results:The mean baseline melanin indices M1 and M2 were 59.54 ± 9.72 and 59.02 ± 9.16, respectively. At the last visit the mean M1 and M2 decreased to 53.8 ± 8.55 (P < 0.001) and 54.13 ± 6.01 (P < 0.001), respectively. Patient and the physician global assessment score showed that 26 (74.3%) and 20 (57.14%) patients, respectively, had >50% pigment clearance.Conclusion:The melanin index, a simple non-invasive parameter is useful in assessing the treatment response more objectively. The 1064-nm Q-switched Nd-Yag laser offers good improvement in patients with nevus of Ota in darker skin types IV/V.

Nevus of Ota in Dark Skin—An Uncommon but Treatable Entity

Abstract: A 1,064 nm q-switched Nd:YAG laser treatment could be an effective and reasonably safe treatment for patients with Nevus of Ota and Fitzpatrick skin type V. Patients should be counselled before treatment regarding the risk of permanent hypopigmentation.
