Objectives: This presentation intends to show, that technology and wavelength of diode lasers can be used for a range of other indications , which allows physicians to gain much higher Benefits from one device, however it is imoortant to know how to selct the correct Parameters for other indications
Diode lasers usually allow to treat with wavelengths of 760, 810, 940
nm mainly are absorbed by melanin ,which is used to treat the pigmentation in hair shafts, in order to destroy the hair bulb by heat for laser hair removal.

Introduction: Also other pigmentation absorb these wavelengths so it can be used to remove pigmented lesions. In low doses with frequent sessions and low energy it is used to do whitening of the skin.
The absorption spectrum of melanin is close to that of hemoglobin and oxyhemoglobin . Diode lasers utilize a wavelength of 800 nm at 5 to 250 millisecond duration, and have been proven to be effective in indications like superficial leg telangiectasis and reticular veins. This procedure can treat Acne inversa (hidradenitis)

Materials / method: Absorption of such wavelengths can be increased by adding gold covered nano particles . Such particles are applied to the skin surface and massaged into the sebaceous glands .Once positioned there the laser wavelength heats the sebaceous glands selectively and destroys them resulting in a long term reduction of papulo-pustular acne. Like many othe wavelengths also diode lasers can be used to ablate tissue, when the tip is held 0,5-1 cm above the target, then heat is maximized on the surface and can be used for ablation procedures. This is mainly done for periodontal regeneration

Results: Absorption of such wavelengths can be increased by adding gold covered nano particles . Such particles are applied to the skin surface and massaged into the sebaceous glands .Once positioned there the laser wavelength heats the sebaceous glands selectively and destroys them resulting in a long term reduction of papulo-pustular acne.
Like many othe wavelengths also diode lasers can be used to ablate tissue, when the tip is held 0,5-1 cm above the target, then heat is maximized on the surface and can be used for ablation procedures. This is mainly done in dentistry for periodontal

Conclusion: Treatment parameters like in hair removal but with longer pulses ,with 3 passes + 3 treatments with 1 month interval create a general heating of skin. resulting in a collagen stimulation like with Radiofrequency used for tightening. Similar effects can be achieved If the parameters are selected like reduced cooling, low fluence and high frequency of shots over 10-20 min .Indications for these kind of parameters are improvement of fine wrinkles , of pore size and improvement of texture .

Objectives: Optimizing our lasers in specific situations in the perioral region.

Introduction: The perioral region is distincted by its different textures and its specific anatomy. The laser treatment differs depending on the location of the lesions: on the skin, on the dry mucosa or on the wet mucosa. Special precautions are necessary at different levels.

Materials / method: Different clinical cases will be presented. According to the laser used (Co2 surgical, fractional and long pulse: Nd Yag 1064nm and Alexandrite 755nm) and according to the nature of the lesion and its location we will show the therapeutic specificities: lip warts, gingival warts, pyogenic granuloma, Foxfordyce granule, supernumerary lip, epulis inflammatory, mucoid cyst, HECK disease, venous lake, old port wine stain (PWS), scleroderma, surgical scar ……

Results: The use of lasers in the perioral region for several indications gives better esthetic results than conventional surgery. These are often simple, quick and less expensive techniques. The postoperative is not heavy with excellent scar quality when the technique is well mastered.

Conclusion: Laser treatment in the perioral region is the treatment of choice for several benign dermatological lesions, most often with an acceptable, even perfect aesthetic result, but has its limits in oncology.

Objectives: A variety of energy based devices have been used to treat acne. However all studies have been subjective and never involved randomized double blind controlled studies.

Introduction: We undertook a randomized controlled study evaluating the use of a 650 usec Nd:YAG laser vs sham in the treatment of moderate to severe acne.

Materials / method: 20 subjects, aged 12-40, with moderate to severe acne were randomized to receive either 650usec, 1064nm Nd:YAG laser treatment vs. sham treatment. All subjects received 3 treatments, two weeks apart with the final session undertaken 4 weeks after the 3rd treatment. Subjects were evaluated for IGA (investigator global improvement) , improvement in inflammatory lesions, improvement in comedonal lesions, total porphyrin score and total sebum score.

Results: The laser treated group showed 1) IGA improvement of 26% vs. 7% for the sham group (a 271% improvement over sham) ; 2) Decrease in the number of Inflammatory lesions of 42% in the treatment group vs. 26% in the sham group ( a 62% improvement over sham); 3) Decrease in total number of
comedones similar to that seen with inflammatory lesions; 4) Decrease in total porphyrin score average of 23% in the treated group vs. 12% in the sham group (a 92% improvement over sham) and 5)An 18%reduction in sebum production vs. 9% in the sham group (an 100% improvement).

Conclusion: This is the 1st study that has compared laser treatment of moderate to severe acne vs a sham treatment. A 650 usec, Nd:YAG laser can effectively treat moderate to severe acne.
