Brief summary

The purpose of this study is to assess the tolerance of tailored 3d-printed transparent face orthosis used in the medical care of post-burn face scar.

Detailed description

Burn injuries are not a rare affection. According to WHO (World Health Organization), in 2004 there were 11 million peoples in the world who were affected by burn injuries caused by fire and who needed medical cares. This important number ignores non-fire thermal, chemical and electrical burns. Face is one of the most susceptible areas of burn where the prevalence was reported to be 6-60%. Hypertrophic scars (HS) are frequent consequences of dermal burn with a prevalence of 70% of burned people. HS, which are a dermal fibro-proliferation, are rigid, erythematous and thickened scars associated with pigmentation abnormalities, xerosis, thermal sensitivity, pain and pruritus. When HS is located on the face, they can cause cosmetic disorder with disfigurement and psychological distress. Pressure therapy and silicone application are the two recommended non-invasive care for prevention and treatment of hypertrophic scarring after burn. On the face, Pressure Garment Therapy (PGT) cannot exert the required pressure because of concave or flat shape so the use of face mask is the most common form of pressure therapy on the face. The face mask manufacturing is artisanal, time consuming and variable between all burn centers. They are not very accurate and have difficulties to apply effective pressure on certain face areas such as nasolabial folds. Our Transparent Face Orthosis (TFO) uses tri-dimensional cam for measurement and 3d-printing technology for manufacturing. We think this way to manufacture the TFO will be more accurate and efficient, less expansive and time consuming. Moreover, the addition of a silicone interface between the TFO and the face will associate silicone application therapy and pressure therapy what should be more effective than pressure therapy alone. The purpose of this study is to assess the tolerance of tailored 3d-printed transparent face orthosis used in the medical care of post-burn face scar.

Number of Local Side EffectsMonth 1wound, device related pain, rash, temporomandibular joint pain, dental pain, suffocating sensation

Secondary

MeasureTime frameDescription
Evaluation of scar evolution with POSASMonth 1; Month 6; Month 12; Month 18; Month 24Evaluation of scar evolution by Patient and Observer Scar Assessment Scale (POSAS). It consists of two scales which assesses vascularity, pigmentation, thickness, relief, pliability, and surface area and it incorporates patient assessment of pain, itching, color, stiffness, thickness and relief. All items were evaluated on numerical rating scales ranging from 1 to 10 (with 10 indicating the worst score).
Wearing timeMonth 1; Month 6; Month 12; Month 18; Month 24Diurnal and nocturnal wearing time in hours
Manufacturing timeMonth 1; Month 6; Month 12; Month 18; Month 24Time of device's manufacturing
Evaluation of scar evolution with VSSMonth 1; Month 6; Month 12; Month 18; Month 24Vancouver Scar Scale (VSS) assesses 4 variables: vascularity (range 0-3), height/thickness (range 0-3), pliability (range 0-5) and pigmentation (0-2). A total scores ranges from 0 to 13, whereby a score of 0 reflects normal skin.
Device lifetimeMonth 1; Month 6; Month 12; Month18; Month 24Device lifetime corresponds to the time between implementation and change of device (for any Reason) in days
Evaluation of the quality of life with the BSHS-BMonth 1; Month 6; Month 12; Month 18; Month 24Evaluation of the quality of life of patients by the BSHS-B (Burn Specific Health Scale - Brief). The BSHS-B consists of 40 items divided into four domains with nine subscales (heat sensitivity, affect, hand function, treatment regimens, work, sexuality, interpersonal relationships, simple abilities and body change). Items are answered on a 5-point Likert scale ranging from 0 (extremely) to 4 (not at all).
Number of Local side effectsMonth 6wound, device related pain, rash, temporomandibular joint pain, dental pain, suffocating sensation
ReprintsMonth 1; Month 6; Month 12; Month18; Month 24Number of reprints needed per patient
