“…Several diagnostic imaging devices methodologies such as computed tomography, magnetic resonance imaging, and ultrasonography (US) have been commonly used to investigate the skin and the subcutaneous fat layer (Foissac et al, ; Gosain et al, ; Gülbitti et al, ; Iyengar et al, ; Schenck et al, ; Wysong et al, ). Due to technical limitation such as a localized low imaging resolution, previous studies could not demonstrate the topography of the skin and superficial fat thicknesses over the entire face.…”

Regional thickness of facial skin and superficial fat: Application to the minimally invasive procedures

et al. 2019

Various recently introduced minimally invasive treatment modalities are now widely used for enhancing the aging face. In a special, filler is used to increase the volume of tissue, and so understanding the regional thickness and distribution of the facial superficial fat is essential for optimizing minimally invasive procedures. The aim of this study was to establish the overall facial skin and superficial fat thicknesses using a three-dimensional (3D) scanning system. From 53 adult Korean and Thai embalmed adult cadavers, the undissected and serially-dissected facial specimens were scanned and reconstructed. The facial skin and superficial fat thicknesses on seven facial regions were calculated from the superimposed images. The facial skin tended to become thicker in the order of the radix and dorsum, and the temple, supraorbital, forehead, perioral, cheek, and infraorbital areas. The skin was thinnest at radix and dorsum (1.51 AE 0.55 mm), and thickest in infraorbital region (1.97 AE 0.84 mm). The facial superficial fat thickness tended to increase in the order of the radix and dorsum, supraorbital, forehead, temple, cheek, infraorbital, and perioral regions. The superficial fat was thinnest at the radix and dorsum (1.61 AE 1.07 mm), and thickest in the perioral region (5.14 AE 3.31 mm). The facial superficial fat thickness tended to increase in the order of the radix and dorsum, supraorbital, forehead, temple, cheek, infraorbital, and perioral regions. The present findings indicate that 3D scanning system can yield crucial anatomical information about depths of the facial skin

“…As the technology has improved, so has its utility. In an early study of over 4300 skin lesions, Wortsman et al demonstrated the ability of higher frequency ultrasound (7)(8)(9)(10)(11)(12)(13)(14)(15) to significantly improve diagnostic accuracy. Compared to clinical examination alone, ultrasound corrected the referring diagnosis in 17% of cases and detected 3 missed malignancies [9].…”

“…HFUS and UHFUS waves, on the other hand, are unable to travel easily through tissue, but provide higher-resolution, superficial detail. This makes HFUS and UHFUS ideal for visualizing a superficial organ like the skin [5,10,11,15,18,19]. Given the diverse range of probe frequencies and the variation of dermal thickness in different regions of the body, specific frequencies should be considered for optimal visualization of lesions in various anatomic locations [15].…”

“…A 2015 study used ultrasound (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18) to determine the prevalence of enthesitis, a feature in the pathogenesis of psoriatic arthritis, among psoriasis patients with and without psoriatic arthritis as defined by CASPAR criteria [67]. The study found at least one ultrasonographic sign of enthesitis in approximately half the patients with psoriatic arthritis, but also in almost half of the psoriasis patients without a diagnosis of psoriatic arthritis [67].…”

High-frequency ultrasound in clinical dermatology: a review

et al. 2021

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.

Injuries caused by surgical incisions or traumatic lacerations compromise the structural and functional integrity of skin. Immediate approximation and robust repair of skin are critical to minimize occurrences of dehiscence and infection that can lead to impaired healing and further complication. Light-activated skin sealing has emerged as an alternative to sutures, staples, and superficial adhesives, which do not integrate with tissues and are prone to scarring and infection. Here, we evaluate both shorterand longer-term efficacy of tissue repair response following laser-activated sealing of full-thickness skin incisions in immunocompetent mice and compare them to the efficacy seen with sutures. Laser-activated sealants (LASEs) in which, indocyanine green was embedded within silk fibroin films, were used to form viscous pastes and applied over wound edges. A hand-held, near-infrared laser was applied over the incision, and conversion of the light energy to heat by the LASE facilitated rapid photothermal sealing of the wound in approximately 1 min. Tissue repair with LASEs was evaluated using functional recovery (transepidermal water loss), biomechanical recovery (tensile strength), tissue visualization (ultrasound [US] and photoacoustic imaging [PAI]), and histology, and compared with that seen in sutures. Our studies indicate that LASEs promoted earlier recovery of barrier and mechanical function of healed skin compared to suture-closed incisions. Visualization of sealed skin using US and PAI indicated integration of the LASE with the tissue. Histological analyses of LASE-sealed skin sections showed reduced neutrophil and increased proresolution macrophages on Days 2 and 7 postclosure of incisions, without an increase in scarring or fibrosis.Together, our studies show that simple fabrication and application methods combined with rapid sealing of wound edges with improved histological outcomes make LASE a promising alternative for management of incisional wounds and lacerations.

Abstract: This is the first study using high-resolution superficial diagnostic ultrasound to map skin thickness of the face and neck at standard anatomic locations. Ultrasound is an inexpensive, noninvasive, and convenient means to monitor dermatologic conditions and guide their treatment.
