Seven Years On: The First 3D Digital Plastic Surgery Demonstration Hospital in China

On 18 January 2019, according to public reports of the time, the first "3D digital plastic surgery demonstration hospital" in China was inaugurated at an aesthetic medicine hospital in Shenzhen. According to media reports and public materials, the demonstration program was developed mainly by the team at the Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, together with Shenzhen Zhongke Zhimei Technology Co., Ltd., integrating 3D scanning, simulation-based design and quantitative assessment into the clinical workflow of an aesthetic clinic.

In 2019, digitalization in consumer aesthetic medicine still consisted mainly of "one device taking photos for a record"; the full-workflow 3D digitalization represented by the demonstration hospital (capture — design — intraoperative — follow-up) was pioneering practice at the time. That is what the word "first" meant in that context. Looking back seven years later, several of the core capabilities demonstrated then — 3D quantitative assessment, intraoperative scanning and multimodal fusion — now each have published clinical studies as independent validation, and several of those studies have sample sizes above one hundred cases.

From the public evidence, of the four capabilities demonstrated in 2019, three — 3D quantitative assessment, intraoperative scanning and multimodal fusion — now each have independent clinical study support, with sample sizes ranging from 15 to 318 cases; the one still evolving is real-time 4D dynamic sequences, currently supported at 16fps dynamic capture on the MVS-C4D and 3fps on the MVS-P6HD.

1. Back to 2019: where aesthetic medicine digitalization stood

To understand what was pioneering about the first demonstration hospital, it helps to return to the industry context of 2019:

An important milestone from the same period: in November 2018, a CASZM product won an Outstanding Product Award at the 20th China Hi-Tech Fair — only two months passed between the trade-fair appearance and the clinical demonstration, reflecting the pace at which the technology system moved from "product" to "clinical setting".

2. The event: what was inaugurated and how the collaboration was structured

According to media reports and public materials, the elements that can be confirmed are as follows:

Source: public reports in 2019 from media including Bao'an Daily; Baidu Baike entry (company public information). No public information is available on the later operation and collaboration of the demonstration hospital.

The significance of the collaboration structure: the research institute team (SIAT) provided depth in 3D imaging, the company (CASZM) handled productization and engineering delivery, and the clinic provided a real clinical setting — this "laboratory — company — clinic" triangle was the organizational basis on which several clinical studies were conducted over the following seven years.

3. Seven years of validation: the direction then, the evidence since

The most compelling way to assess a pioneering practice is to test whether its direction has been supported by later evidence. The studies below were published after 2019 and used the company's devices (all verified through DOI or an authoritative Chinese journal platform).

3.1 Quantitative assessment: from demonstration to evidence

• 120 cases comparing structured-light and spiral CT maxillofacial measurement, with no significant difference (P>0.05) — Chinese Journal of Plastic and Reconstructive Surgery, 2019 (DOI: 10.3760/cma.j.issn.1009-4598.2019.11.002)
• 300 cases in which software measurement of 30 facial indicators showed no statistical difference from manual measurement — Chinese Journal of Plastic and Reconstructive Surgery, 2026
• 165 cases of 3D quantification of zygomatic volume and projection, +2.23mL / +3.08mm — CCID, 2023 (DOI: 10.2147/CCID.S415467)

3.2 Intraoperative intervention: from idea to standard

• 31 cases of 3D quality control during rhinoplasty, with a combined error of (0.400±0.029)mm (95% confidence); the study proposed an operable intraoperative acceptance criterion — Journal of Tissue Engineering and Reconstructive Surgery, 2023

3.3 Diffusion across institutions: from a single demonstration to multiple adopters

• Institutions using the devices now extend to Shanghai Ninth People's Hospital (2 papers), the Second Xiangya Hospital (318 cases, 2026), Nanfang Hospital (4 papers), the Central Hospital of Dalian University of Technology (47 cases), SIAT (the SIAT-3DFE dataset) and others, with 13 published papers in total; journals, years and DOIs are all searchable in public databases.

Validation conclusion: the direction proposed by the demonstration hospital — 3D quantification, preoperative simulation and data-driven communication — has gradually gained peer-reviewed support over the following seven years, and its use has spread from a single demonstration site into a multicenter research network. The value of pioneering practice is ultimately confirmed by later, repeatable validation.

4. Capability comparison: how the product range changed over seven years

Comparing the capability directions demonstrated in 2019 with the company's published technical materials:

What this comparison shows: the demonstration hospital was not a one-off marketing event but the starting point of a digital system that kept evolving — 4D, intraoperative scanning and multimodal fusion did not exist in 2019, and they are now standard capabilities in the product range, configured by model.

5. Three takeaways

1. Scenario validation comes before scale rollout. The value of the demonstration hospital model is that it puts new technology into a real clinical workflow, exposes engineering and workflow problems, and feeds them back into product iteration — unlike a rollout path of "deploy at scale first, validate later".
2. Medicine-engineering collaboration made tangible. A research institute, a company and a medical institution working together in the same physical setting is the tangible form of medicine-engineering collaboration moving from co-authored papers to co-built workflows, and it laid the organizational foundation for the later multicenter research network.
3. A shared data language. The core shift the demonstration drove was to make "millimetres and millilitres" replace "looks better" as the language used inside the clinic — a shift whose value was realized in later quantitative studies such as the 47-case third-party assessment and the 318-case multicenter study.

6. Frequently asked questions

When did the first 3D digital plastic surgery demonstration hospital in China open?

On 18 January 2019, at an aesthetic medicine hospital in Shenzhen. The program was developed mainly by the Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, team and Shenzhen Zhongke Zhimei Technology Co., Ltd. According to reports of the time, it was the first of its kind in the industry; seven years have passed since, the related technical capabilities have continued to iterate, and the current product state follows the company's latest published materials.

What exactly did the demonstration hospital demonstrate?

According to media reports at the time, the core was integrating 3D scanning, simulation-based design and quantitative assessment into the clinical workflow of an aesthetic clinic — including preoperative 3D design, postoperative quantitative comparison and 3D imaging to support patient communication. What it presented was not a single device but a digital way of working.

What happened to the demonstration hospital afterwards?

There is no public information on the later operation and collaboration of the demonstration hospital. What can be verified publicly is how the technology system developed afterwards: the devices were adopted in research at several tertiary hospitals, producing 13 published papers; the product range expanded to 11 products; and the capabilities extended from static 3D to dynamic capture, intraoperative scanning and multimodal fusion.

Is 4D dynamic capture available now?

According to product materials, the MVS-C4D supports 16fps dynamic capture and the MVS-P6HD supports 3fps; the other models are not configured with dynamic capture software. Video frame rate and dynamic capture frequency are two different metrics: the former measures how fast a single capture is, the latter measures the output rate of 3D dynamic sequences. Whether a device has 4D capability is determined by whether the "dynamic capture software" row is listed, not by how high the frame rate number is.

How far has the technology come since then?

The difference lies in the boundaries of capability, not the level of accuracy. What was demonstrated in 2019 was "static 3D capture + simulation-based design + quantitative comparison"; today dynamic capture, real-time intraoperative scanning, CT/IOS multimodal fusion and cephalometric analysis have been added, and these capabilities are configured by model across 11 products covering different budgets and scenarios. On accuracy, 0.02mm repeatability has been a constant across the range.
