  Purpose

A pilot study will be conducted on 2 type of subjects, one with plastic surgery scar with a randomization of laser treated portions, and other with keloid excision scar with a complete laser treatment. The aim is to evaluate the infra-red diode laser influence on keloid recurrence and scar prevention. The keloid recurrence rate will be evaluated at each visit, and the scar prevention in plastic surgery will be evaluated comparing laser treated portion and non-treated portion.

Primary Outcome Measures:
  • treatment tolerability assessed by natures, intensity and incidences of the side effects, with a special oversight of skin burn lesion [ Time Frame: 10 days after surgery or excision ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • improvement of scarring for plastic surgery group [ Time Frame: 12 months after surgery ] [ Designated as safety issue: No ]
    • Vancouver Scar Scale score
    • Comparative scar assessment scale
    • Observer assessment score (POSAS)

  • keloid recurrence, an intralesional corticotherapy will be set up as soon as there is a recurrence. [ Time Frame: 12 months after excision ] [ Designated as safety issue: Yes ]
    • Lesion size
    • Vancouver scar scale
    • Observer scar scale (POSAS)

  • quality of life assessment for keloid group [ Time Frame: 12 months after excision ] [ Designated as safety issue: No ]
    • VQ-dermato
    • satisfaction questionnaire

  • Socio and medical economic evaluation for keloid group [ Time Frame: 12 months after excision ] [ Designated as safety issue: No ]
