“…Since the introduction of selective photothermolysis, Q-switched lasers have been used for the treatment of pigmented lesions [1][2][3][4][5]. Although Q-switched Ruby and Alexandrite lasers are highly effective in the treatment of lentigines, for dark skinned patients such as Asians with a higher epidermal melanin content, the risk of complications such as erythema, blistering, and post-inflammatory hyperpigmentation (PIH) post-laser surgery increased.…”

Q‐switched ruby versus long‐pulsed dye laser delivered with compression for treatment of facial lentigines in Asians

Background and Objectives: Q-switched lasers have been used for the treatment of lentigines but postinflammatory hyperpigmentation (PIH) can be an issue especially in Asians. The 595 nm long-pulsed dye laser (LPDL) has been used for the treatment of vascular lesions and although it is well absorbed by oxyhemoglobin, it is also absorbed by melanin. To use this device for the treatment of facial lentigines, we attached a flat glass lens to the tip of the laser's handpiece, allowing compression of the skin during treatment. In doing so, eliminated the absorption by oxyhemoglobin. This prospective study aims to compare the efficacy and complications of such an approach to the use of Q-switched ruby laser (QSRL) in the treatment of facial lentigines in Asians. Study Design/Materials and Methods: Eighteen Asian patients (1 male, 17 female) with facial lentigines Fitzpatrick skin types III-IV were enrolled. One of the lentigines present was treated with LPDL by compression method and the other one was treated with QSRL. A LPDL emitting wavelength of 595 nm, spot size of 7 mm was used, with fluence between 10 and 13 J/cm 2 and pulse duration of 1.5 milliseconds. Cryogen spray cooling was not used. A 694 nm QSRL was used with a spot size of 4 mm, fluence of 6-7 J/cm 2 , and pulse duration of 30 nanoseconds. Lightening of the lesions was assessed by reflectance spectrometer Erythema, hypo-or hyperpigmentation and scarring were also assessed by clinical examinators. Results: The degree of clearing achieved with the two lasers was 70.3% and 83.3% for QSRL and LPDL, respectively. All QSRL treated areas developed erythema whereas only 4 of 18 LPDL treated areas developed erythema. Hyperpigmentation was seen in four patients after QSRL, but not after LPDL. There was no scarring or hypopigmentation. Conclusions: LPDL delivered with a compression method is more effective than QSRL for facial lentigines. Complications after LPDL treatment were substantially less frequent than after QSRL. The addition of compression technique may allow ''vascular'' pulsed dye laser to be used for treating a variety of pigmented lesions. Lasers Surg. Med. 38:94-97, 2006. ß 2005 Wiley-Liss, Inc.

“…Specifically, the results obtained using the QS Nd: YAG and QS alexandrite lasers are remarkable, with almost Case presentation complete responses (23,24). While one report did not find any difference in efficacy (25), other two stu dies provided some evidence indicating that QS ruby laser was more efficient than QS Nd:YAG 1064 and 532 (26,27). A new approach with Ota naevus is to start treatment at an early age (before the age of 10), which allows to use lower fluences of QS laser, reducing the potential side effects.…”

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.

ÖzetDerinin pigmente lezyonları, kozmetik ve psikolojik rahatsızlıklar oluşturabilen sık karşılaşılan durumlardır. Pigmente lezyonların tedavisinde lazer kullanımı Q-anahtarlı lazerlerin kullanıma girmesiyle son yirmi yılda artmıştır. Pigment spesifik ve pigment spesifik olmayan lazerler; lentigo, nevüs, melazma, efelid, cafe au lait makülleri, Becker nevus, postinflamatuar hiperpigmentasyon gibi pek çok farklı pigmente lezyonun tedavisinde etkin ve güvenilir olarak kullanılmaktadır. Pigmente lezyonlar epidermal, dermal-epidermal ve dermal yerleşimlerine göre değerlendirilmekte ve lezyon derinliğine göre uygun lazer sistemi ile tedavi edilmektedir. Pigmente lezyonların tedavisinde olası komplikasyonlar ve malinite riski çok iyi değerlendirilmeli ve hasta için en uygun lazer sistemi tercih edilmelidir. Uygun hastalarda doğru lazer sistemi kullanıldığında tedavi etkinliği ve güvenirliği oldukça yüksektir. (Türk derm 2012; 46 Özel Sayı 1: 23-9) Anah tar Ke li me ler: Deri, pigmente lezyon, lazer, tedavi Sum maryPigmented lesions of skin are common situations that can lead to cosmetics and psychological disorders. In last twenty years, usage of lasers in the treatment of pigmented lesions is increased with the introduction of Q-switched lasers. Pigment specific and pigment nonspecific lasers can be used safety and effectively in the treatment of various pigmented lesions including lentigo, nevus, melezma, ephelides, cafe au lait macules, Becker's nevus and postinflammatory hyperpigmentation. Pigmented skin lesions are evaluated by their epidermal, dermal-epidermal and dermal locations and the most appropriate laser system is chosen by its location. The risk of complications and malignancy should be considered very carefuly before the treatment and the most appropriate laser system should be chosen for the patient. Efficacy and safety of the laser treatment is very high in selected patients which were treated by appropiate laser systems. (Turk derm 2012; 46
