Emerging Technologies.

In this article, an array of new developments in burn care, from diagnosis to post-burn reconstruction and re-integration, will be discussed. Multidisciplinary advances have allowed the implementation of technologies that provide more accurate assessments of burn depth, improved outcomes when treating full-thickness burns, and enhanced scar tissue management. Incorporating these new treatment modalities into current practice is essential to improving the standard of burn care and developing the next generation of burn wound management methodologies.

Minimally invasive burn reconstruction with subcutaneous scar contracture release.

BACKGROUND: Scar contracture bands after burns are frequent problems that cause discomfort and physical limitation. This study investigates the efficacy of a minimally invasive contracture band release technique (MICBR) inspired by closed platysmotomy. METHODS: Patients with burn scars treated with MICBR in our center were included retrospectively. Our routine scar and contracture treatments (non-invasive and invasive) were utilized prior to undergoing MICBR. Range of motion (ROM) and Vancouver Scar Scale was measured before and after the procedure when feasible. RESULTS: Forty-five patients were included, with 97 total contracture sites treated all over the body. An average of 1.6 sites were treated per patient, with a maximum of six. Patients age was 6-68 years; total burn surface area ranged from 0.5% to 85%. 24% were performed under local anesthesia. 84% were in originally skin grafted areas. We found significant improvements in ROM and VSS. 84% of patients surveyed were "satisfied" or "very satisfied". 95% reported improved mobility. No significant adverse events occurred. CONCLUSION: This MICBR technique is a versatile, safe, and well-tolerated adjunct procedure that can help patients regain mobility after a burn injury.

Morel-Lavallée Lesion with Friction Burn: Management Using Veraflo Vac Dressing, Preserving Body Contour.

While the standard of care for subcutaneous degloving injuries (Morel Lavallee lesion) in conjunction with friction burns is drainage, wide excision and grafting, this case was treated with drainage and continuous lavage with the help of the noncompressible Veraflo Vac dressing. This led to rapid reattachment of the tissues and preservation of body contour long term.

Assessment of Hair Density and Sub-epidermal Tissue Thickness in Burn Scars Using High-Definition Ultrasound Imaging.

Burn scars show significant differences in structure, pigment, and hair density/sparsity from unburned skin, yet no formal documentation of these changes can be found in the literature. Evaluation of these differences is essential to assessing future intervention outcomes. The study was a prospective controlled clinical trial. Included were 19 adult burn survivors (18-63 years old, average age 47; 15 male, 4 female, 14 Caucasian, 2 African American, 1 Hispanic; 11 flame burns, 5 scald burns, 2 grease burns and 1 electrical burn, 2%-60% TBSA) with conspicuous, mature scars. All study subjects had either skin-grafted or nongrafted scars, as well as healthy skin in the same body area, to control for intraindividual variability. All scars were at least 9 months old and at a minimum 2 × 2 cm2 in size. On each individual, at least one nongrafted scar or one grafted scar and healthy skin was imaged with a high-definition ultrasound device (Longport, Inc., Glen Mills, PA, 35MHz probe, 1500 m/s). Vancouver scar scale was assessed. Although scarred skin had significantly fewer follicles than healthy skin in both grafted (P < .0001) and un-grafted sites (P = .0090), there were even significantly fewer follicles in grafted scars than un-grafted scars (P = .0095). In thickness of the sub-epidermal layer, there was no difference between grafted and un-grafted scars (P = .1900). Both kinds of scars had a significantly thicker sub-epidermal layer than healthy skin (P = .0010). Vancouver scar scale was 7.4 for grafted and 4.6 for nongrafted scars with grafted flame burn scars ranging higher than all others (5-11). There was no discomfort during the imaging, and no adverse events occurred during the study period. Our study demonstrates two clear morphologic differences between scars and healthy skin: thickness of the sub-epidermal layer and hair follicle density. Grafted burn scars were shown to contain fewer hair follicles than un-grafted scars.

Exploration of nonsurgical scar modification options: can the irregular surface of matured mesh graft scars be smoothed with microdermabrasion?

The purpose of this study was to determine, in principle, whether microdermabrasion can alter waffle-pattern (meshed split-thickness skin graft) burn scars after scar maturation. Matured waffle-pattern mesh-graft scars were treated with multiple microdermabrasion sessions over the course of a year (maximum 20). Before and after treatment, the treated scars and the control scar on the same patient were assessed with subjective and objective scar assessment tools (scar scales, cutometer [elasticity], laser Doppler flowmeter [vascularity], Semmes-Weinstein filaments [sensation], and high-resolution ultrasound [thickness]). The treatment resulted in continuous improvement of some physiologic skin functions like perfusion response (feedback), thickness, and elasticity when compared with nontreated scar, although no statistical significance was reached. Both Vancouver scar scale and patient assessment scales showed significant improvement. The study showed that even mature waffle pattern scars can be modified by minimally invasive interventions. Larger study groups and more economic treatment modalities need to be studied in the future.
