“…3D technologies can provide alternatives for these traditional clinical treatments through digital automation and higher precision without needing any physical contact with the patient. [5][6][7] Several technologies have been investigated for 3D scanning including magnetic resonance imaging (MRI), computedtomography (CT), laser triangulation, structured light and photogrammetry. [8][9][10][11][12][13] Each of these methods vary in quality of scan produced, ease-of-use, portability and cost.…”

Purpose: Three-dimensional (3D) facial scanning is an emerging clinical tool to capture external anatomical features for quantitative assessment and treatment in a wide range of clinical settings. Materials and Methods: In this study, an economical approach for rapid scanning of faces in the clinic was developed and validated to record valuable 3D patient data using smartphone cameras and photogrammetry software. Five novice operators were recruited to watch an instructional video developed on the technique before scanning 20 healthy adult participants. Results: The smartphone-based photogrammetry approach produced scans with 1.3 mm (±0.3 mm) accuracy in comparison to a metrology-rated gold standard device and were 88% (±14%) complete, with no significant difference observed between operators. A moderate to strong intrarater reliability was determined for all novice operators, suggesting that first-use operators can capture consistent scans based on watching an instructional video. Conclusion: Smartphone photogrammetry could provide a rapid, noninvasive and economical method to capture patient morphological data for clinical assessment and personalized device manufacture. Inexperienced operators can quickly learn and utilize smartphone photogrammetry to provide accurate and reliable facial scans, essential for future clinical translation.

“…The study also reported significant decrease in scar hardness after 1 month of follow-up in both groups. In the study by Wei et al, 12 one item of both the Patient and Observer Scale (the overall assessment of the scar) decreased significantly for all patients after 1 month of treatment. For the Observer Scale, the overall score decreased significantly in all patients.…”

“…The included articles originated from China (two) and the Netherlands (one) and were published in 2016 and 2017. Two articles described patients with hypertrophic scars caused by thermal or chemical burns 12,13 and one study 14 included patients with hypertrophic scars and protruding skin flaps after facial flap surgery.…”

Background: Severe facial hypertrophic scars are known to severely impact emotional well-being. Pressure therapy by means of transparent face masks has been used for almost 40 years, but evidence about the clinical effects remains sparse. Objectives: To provide a summary on the efficacy of transparent face masks in the treatment of facial hypertrophic scars. Methods: A literature search was conducted in PubMed, MEDLINE, and Cochrane databases through 1 January 2018. Articles describing the clinical effects of facial pressure therapy for remodeling the face after trauma or surgery with a validated tool were included. This review included studies of participants treated with facial hypertrophic scars, both minors and adults. Results: Three articles involving 33 patients were selected for inclusion. Two studies described statistically significant improvement in facial scars measured by durometer, ultrasound, and the Patient and Observer Scar Assessment Scale (POSAS). Conclusions: Facial pressure masks have been shown to deliver significant improvement in facial scars, measured by both subjective and objective tools. However, only three studies could be included in this literature review. Also, because of considerable limitations of the studies, it remains difficult to draw substantial conclusions about the efficacy of transparent face masks. Clinical relevance This literature review provides a summary of the current evidence on the subjectively and objectively measured clinical effects of transparent face masks in the treatment of facial scars, highlighting the need for further research on this topic.

“…The platform overview presents the integrated framework for the controlled fabrication of HLMs, comprising computational design, digital fabrication, and genetic engineering techniques ( Figure ). The biohybrid face mask featured in this example was digitally modeled to custom fit a human face and produce a prescribed biological response (i.e., colored patterning indicating locally tunable gene‐regulated protein expression), demonstrating a potential use as a delivery system for topical therapies relating to site‐specific and custom facial devices and bacterial therapies …”

Significant efforts exist to develop living/non‐living composite materials—known as biohybrids—that can support and control the functionality of biological agents. To enable the production of broadly applicable biohybrid materials, new tools are required to improve replicability, scalability, and control. Here, the Hybrid Living Material (HLM) fabrication platform is presented, which integrates computational design, additive manufacturing, and synthetic biology to achieve replicable fabrication and control of biohybrids. The approach involves modification of multimaterial 3D‐printer descriptions to control the distribution of chemical signals within printed objects, and subsequent addition of hydrogel to object surfaces to immobilize engineered Escherichia coli and facilitate material‐driven chemical signaling. As a result, the platform demonstrates predictable, repeatable spatial control of protein expression across the surfaces of 3D‐printed objects. Custom‐developed orthogonal signaling resins and gene circuits enable multiplexed expression patterns. The platform also demonstrates a computational model of interaction between digitally controlled material distribution and genetic regulatory responses across 3D surfaces, providing a digital tool for HLM design and validation. Thus, the HLM approach produces biohybrid materials of wearable‐scale, self‐supporting 3D structure, and programmable biological surfaces that are replicable and customizable, thereby unlocking paths to apply industrial modeling and fabrication methods toward the design of living materials.
