Laser Therapy for Dermatological Skin Applications
excerpt taken from Dr. Toshio Ohshiro's paper: "27 YEARS OF LASER TREATMENT:
A PERSONAL PERSPECTIVE"
Dermatological Applications
Following early success in the pain clinic, I moved on to assess the use of LLLT in dermatology-related diseases and conditions, including hypertrophic scars and keloids,(17) revitalization of failing skin grafts and flaps,(18,19) hyperand
hypopigmentation, vitiligo,(20) atopic dermatitis, atrophic skin, psoriasis vulgaris, strawberry hemangioma in infants,(21) and so on. Figure 17 shows the progress over two years of the use of LLLT alone (830 nm, 60 mW, cm, 30 J/cm2) in treatment of a hypertrophic keloid following an abdominal operation in a female. Figures 18 and 19 show the effective use of LLLT in the treatment of systemic
vitiligo. Figures 20 and 21 show laser therapy used to effective by control and treat atopic dermatitis, an increasing problem here in Japan. Figure 22 shows the use of laser therapy in the combination of iatrogenic vitiligo and border hyperpigmentation caused by overtreatment of a systemic vitiligo with PUVA (psoralen and UVA) therapy. LLLT reduced the hyperpigmented border and restored some normal pigment to the hypo- and depigmented zone, with a very cosmetically-acceptable result. Strawberry hemangiomas (SHs) are a major problem for infants and their parents. The conventional wisdom adopts a 'wait and see' attitude, as a large majority of these troubling lesions spontaneously resolve. However some may involve the eyes, threatening the sight of the patient. Others can involve and restrict the nasal airway. Many are subject to frequent bleeding, either spontaneous or through self-excoriation. In these cases, treatment is certainly required. However, we treat all SHs with LLLT, as the involution phase is reached much earlier, and very often with much better results. Figure 23 shows a representative example of the course of successful involution of large SHs on the arm of young girl.
