Summary

Skin injuries due to trauma are relatively common, and patients are very concerned about scars caused by trauma and primary repair. Recently, the use of ablative and non-ablative lasers based on the fractional approach has become a novel strategy for the treatment of scars.

The objective of this study is to compare the efficacy of dual-mode Er:YAG laser delivering pulses either with and without heat/coagulation in a cohort of patients with long keloid/hypertrophic scars.

The main hypothesis is that ablative fractional laser without heat/coagulation is equivalent to laser with heat/coagulation in terms of scars volume reduction, while the secondary hypothesis is that ablative fractional laser without heat/coagulation is superior in terms of post-operative erythema and hypopigmentation reduction.

Conditions

  • Keloid
  • Hypertrophic Scars

Interventions

DEVICE

Laser coagulation

The treatment consists in performing Er:Yag laser with long-pulsed Erbium mode

DEVICE

Laser w/o coagulation

The treatment consists in performing Er:Yag laser with true pulsed Erbium mode
