Very few objective scar evaluations have been conducted with burn survivors, which limits our knowledge of the clinical recovery profile of hypertrophic scars (HSc) and donor site scars (D). The purpose of this study was to prospectively quantify the skin characteristics of post-burn HSc in different anatomical locations (D) and normal skin (N) using objective instrumentation. The skin characteristics of HSc, D, and N in 44 burn survivors were measured at 2, 3, 4, 5, 6, and 7 months post-burn using validated instrumentation: a high-frequency ultrasound (for thickness), Cutometer® (for pliability), and Mexameter® (for erythema and pigmentation). Up to five sites were assessed on the same participant, if their scar was located on the upper extremity (UE), lower extremity (LE), and trunk. A mixed model two-way analysis of variance was used to investigate the differences in means between sites at each time point and between time points at each site. The results revealed that the HSc sites were thicker than the D and N at all time points; the UE and trunk HSc were thicker than the LE HSc at 7 months post-burn; the pliability of the trunk HSc did not improve over time; and the UE HSc was more erythematous at 7 months, compared to other anatomical sites, whereas the D erythema decreased from 2 to 7 months. As clinicians have prioritized UE treatments due to their functional importance, this study provides objective measurements to further support this practice and encourages clinicians to also prioritize trunk HSc treatments after burn injuries.

Abstract Background Ultrasound was first introduced in clinical dermatology in 1979. Since that time, ultrasound technology has continued to develop along with its popularity and utility. Main text summary Today, high-frequency ultrasound (HFUS), or ultrasound using a frequency of at least 10 megahertz (MHz), allows for high-resolution imaging of the skin from the stratum corneum to the deep fascia. This non-invasive and easy-to-interpret tool allows physicians to assess skin findings in real-time, enabling enhanced diagnostic, management, and surgical capabilities. In this review, we discuss how HFUS fits into the landscape of skin imaging. We provide a brief history of its introduction to dermatology, explain key principles of ultrasonography, and review its use in characterizing normal skin, common neoplasms of the skin, dermatologic diseases and cosmetic dermatology. Conclusion As frequency advancements in ultrasonography continue, the broad applications of this imaging modality will continue to grow. HFUS is a fast, safe and readily available tool that can aid in diagnosing, monitoring and treating dermatologic conditions by providing more objective assessment measures.
