“…Lasers have been used to treat scars for years with the preferred treatment technique depending on the type of scarring [12][13][14][15]. For erythematous hypertrophic scars and keloids, the nonablative 585-nm pulsed dye laser is the gold standard and the treatment technique based on the concept of selective photothermolysis [16,17].…”

“…The known factors that influence the normal wound hea lin g are divided into general a nd local (18). The h e a l i n g process a l s o depends on the scar's anatomical location and its orientation (along Langer's lines), skin p h o t o type, and i ncisi on t y p e (19,20).…”

Back ground: Physiotherapy has a very important role in the maintenance of the integumentary system integrity. There is very few evidence in humans. Nevertheless, there are some studies about tissue regeneration using low-level laser therapy (LLLT). Aim: To analyze the effectiveness of LILT on scar tissue. Methods: Seventeen volunteers were stratified by age of their scars, and then randomly assigned to an experimental group (EG) -n = 9 -and a placebo group (PG) -n = 8. Fifteen sessions were conducted to both the groups thrice a week. However, in the PG, the laser device was switched off. Scars' thickness, length, width, macroscopic aspect, pain threshold, pain perception, and itching were measured. Results: After 5 weeks, there were no statistically significant differences in any variable between both the groups. However, analyzing independently each group, EG showed a significant improvement in macroscopic aspect (p = 0. 003) using ILLT. Taking into account the scars' age, LILT showed a tendency to decrease older scars' thickness in EG. Conclusion: The intervention with LLLT appears to have a positive effect on the macroscopic scars' appearance, and on old scars' thickness, in the studied sample. However, it cannot be said for sure that LLLT has influence on scar tissue.

“…Er:YAG laser is effective in resurfacing skin with fine and superficial atrophic scars, yielding similar results to that of CO 2 laser, Er:YAG reepithelialization typically takes 4-7 days so it decreases postoperative erythema and recovery times [13,14].…”

Aim: To determine the effect of Er:YAG laser in the management of post-burn scars and to compare its effect to ablative and fractional lasers. Patients and methods:50 patients with post-burn scars were recruited and randomly divided into 2 groups: Group I patients had ablative Er:YAG laser mode therapy and Group II patients had fractional Er:YAG laser rmode therapy. Vancouver scar score (VSS) was recorded for each group pre-and postoperatively, both groups showed an increase in the VSS and histopathological findings. Results:The obtained results showed morphological changes immediately after treatment, the skin surface displayed a white-gray frost, which on close inspection revealed a point pattern corresponding to individual laser columns done by fractional laser treatment. Conclusion:Ablative and fractional modes of Er:Yag laser can be used for treatment of post-burn hypertrophic scars. Ablative laser mode had better results than fractional laser mode as indicated by clinical assessment, VSS and changes of histopathological findings.
