The NFS Study: 50 Deaths from 2016 to 2024 Explained
The 국립과학수사연구원 (Gungnipchajanggwasasuyeongu-won, National Forensic Service — hereafter NFS) is South Korea’s official forensic body, operating under the Ministry of the Interior and Safety and responsible for cause-of-death investigations nationwide.¹ Between 2016 and 2024, the NFS linked 50 deaths to plastic surgery procedures through its forensic cause-of-death analysis program.¹
That headline figure — 50 deaths in nine years — demands two pieces of context before it can be meaningfully interpreted.
Context one: procedure volume. KHIDI (Korea Health Industry Development Institute) recorded 1,170,467 foreign patients receiving treatment in Korea in 2024 alone, with plastic surgery and dermatology collectively representing the largest share of procedures sought by international visitors.² That figure excludes domestic Korean patients, who represent the majority of total procedure volume. Estimating conservatively, annual total cosmetic procedure counts run into the hundreds of thousands. Against that denominator, 5–6 deaths per year represents a low absolute mortality rate — though not a negligible one.
Context two: what the NFS counts. The NFS investigation framework captures deaths that reach forensic inquiry — cases where the cause of death was disputed, unexplained, or flagged by family or healthcare providers. Deaths attributed at the clinical level to unrelated causes, or cases settled quietly before forensic referral, may not appear in the dataset. The 50-death figure is therefore a floor, not a ceiling.
The leading cause across the 50 cases was anesthesia-related complications. Approximately 23 cases — nearly half — involved anesthesia as a primary or contributing factor.¹ This finding aligns with global surgical safety literature, which consistently identifies anesthetic management as the highest-leverage variable in elective surgery mortality. The implication for prospective patients is direct: the qualification and continuous presence of the anesthesiologist managing your procedure is at least as important as the surgeon’s technique.
The NFS also found elevated mortality risk in procedures performed outside licensed hospital settings — in non-surgical office environments not authorised for the level of intervention being performed.¹ Facility licensing is therefore not bureaucratic formality; it correlates with actual outcome data.
Which Procedures Carry the Highest Risk
The NFS data identifies three procedure categories as disproportionately represented in the 50 fatalities: liposuction (particularly large-volume liposuction), facelift surgery, and combined multi-procedure operations performed in a single session.¹
Large-volume liposuction carries two distinct physiological risks that explain its prominence in mortality data. First, fat embolism — where fat particles enter the bloodstream and obstruct pulmonary vessels — is a rare but rapidly fatal complication. Second, fluid imbalance: large-volume procedures involve significant fluid shifts that require precise intraoperative management; errors in fluid administration can precipitate cardiovascular collapse. Neither risk is unique to Korea, and both are well-documented in international liposuction safety literature.
Facelift surgery (리프팅 수술, ripeutting susul) appears in the high-risk category partly because it is frequently performed on older patients with higher baseline cardiovascular risk, and partly because it is often combined with other procedures in a single operative session — amplifying anesthesia duration.
Multi-procedure same-day combinations represent the category with the most direct implication for patient decision-making, because procedure stacking is a choice rather than an inherent property of any single operation.¹ Clinics that market “package” days combining rhinoplasty, eyelid surgery, fat grafting, and liposuction in one session are extending anesthesia time well beyond what any single procedure would require.
The contrast between rhinoplasty and eyelid surgery — the two most frequently searched procedures for international patients — versus liposuction and facelifts matters practically. High search volume for the former does not mean high mortality risk; the NFS data suggests the reverse.
How Korea Compares to Other Countries
Direct international comparison of plastic surgery mortality rates is methodologically difficult. Countries collect this data differently: the United States tracks deaths through accreditation bodies such as the American Association for Accreditation of Ambulatory Surgery Facilities (AAAASF) and state medical board incident reporting, while Korea’s NFS operates as a forensic post-mortem investigation system rather than a prospective surgical registry. Neither system captures all events.
With that caveat stated, the available data does not support a conclusion that Korean plastic surgery is inherently more dangerous than equivalent procedures in the US, Australia, or Western Europe when performed in comparable facility types. Studies from the US estimate liposuction mortality at approximately 1.3–2.0 deaths per 100,000 procedures. Korea’s NFS figures, applied against conservative estimates of annual liposuction volume, produce a rate in a broadly similar range.
Where Korea diverges — and where the NFS data provides the clearest signal — is in the unlicensed facility category. Procedures performed in non-surgical office environments in Korea carry elevated mortality risk relative to licensed hospital settings.¹ This risk category is not unique to Korea, but the concentration of high-volume cosmetic clinics in dense urban areas like Gangnam-gu (which receives approximately 60% of medical tourists seeking aesthetic procedures)² creates conditions where the distinction between clinic types can be obscured by marketing.
Brazil is frequently cited as a high-risk comparator market, with published mortality rates for liposuction meaningfully above the global average — attributed to large-volume procedures, combined operations, and less stringent outpatient facility oversight. Korea’s regulatory framework is more structured than Brazil’s in this respect, though enforcement consistency across the thousands of registered aesthetic clinics is not uniform.
What the Statistics Mean for Your Individual Risk
Population-level statistics describe distributions, not individual outcomes. The 50 deaths recorded by the NFS between 2016 and 2024 tell you where risk concentrates; they do not tell you what your personal probability of harm is, because that depends on variables the aggregate data cannot see: your cardiovascular baseline, the specific surgeon’s complication rate, the anesthesiologist’s qualifications, the facility’s emergency protocols, and whether you are scheduling one procedure or five.
Several individual-level risk modifiers emerge clearly from the NFS findings.
Procedure type is the strongest signal. Choosing a standalone rhinoplasty or eyelid procedure carries materially lower risk than scheduling large-volume liposuction or a facelift combined with multiple other operations.¹ If your planned procedure list includes liposuction above a low volume threshold, the risk profile shifts.
Facility licensing is a binary, not a spectrum. Procedures performed outside licensed settings carry documented elevated mortality risk.¹ The difference between a licensed surgical facility and an unlicensed office environment is not a matter of degree — it is the difference between having resuscitation equipment and trained staff present or not.
Anesthesia management is not a background variable. Nearly half of all NFS-recorded deaths involved anesthesia as a factor.¹ The qualification of the person managing your anesthesia — specifically whether a dedicated, board-certified anesthesiologist (not a nurse or the operating surgeon) is present throughout your procedure — is a first-order risk variable.
Your risk as an individual is lower than the aggregate statistics might imply if you select accredited facilities, avoid procedure stacking, and verify anesthesia staffing before consenting. It is higher if you prioritise cost minimisation over those factors.
How to Lower Your Risk Based on the Data
The NFS findings point to specific, actionable risk reduction steps. These are not generic precautions — each item below maps directly to a documented fatality pathway in the dataset.¹
Before booking:
- Confirm the clinic holds a valid Korean medical institution licence for surgical procedures — request the registration number and verify it through the Korean Ministry of Health and Welfare’s public registry
- Ask explicitly whether a dedicated anesthesiologist (not the surgeon, not a nurse anesthetist operating independently) will be present for the full duration of your procedure; nearly half of recorded deaths involved anesthesia complications¹
- Review the surgeon’s board certification — Korean plastic surgeons should hold certification from the 대한성형외과학회 (Daehan Seonghyeongoagwahakhoe, Korean Society of Plastic and Reconstructive Surgeons)
When planning your procedure list:
- Stage major procedures across separate surgical dates rather than combining them in a single session; the NFS specifically flags combined multi-procedure days as a high-risk category¹
- If liposuction is planned, discuss volume thresholds with your surgeon — large-volume liposuction carries a distinct risk profile compared to limited-volume work¹
- Be cautious of clinic packages that bundle four or more procedures into one operative day; marketing convenience does not change the physiological cost of extended anesthesia
On the day:
- Confirm post-operative monitoring arrangements before your procedure begins — where will you recover, for how long, and who is monitoring you; post-operative monitoring failure appears in the NFS fatality record¹
- Ensure you have a companion who can advocate for you if you cannot communicate in Korean during recovery
Often a good candidate
- Scheduling a single, standalone procedure under general or local anesthesia
- Using a facility with a valid surgical licence and dedicated anesthesiologist on staff
- In good baseline cardiovascular health with no contraindicated comorbidities
- Staging a multi-procedure plan across separate surgical dates
Should reconsider or wait
- Combining two or more procedures in one session — discuss with your surgeon and anesthesiologist whether the risk-benefit balance supports it
- Any history of anesthesia sensitivity, clotting disorders, or significant cardiovascular conditions — requires specialist pre-operative clearance
- Planning large-volume liposuction — confirm facility has ICU-level monitoring capability
Not a suitable candidate
- Procedures in facilities that cannot confirm valid surgical licensing
- Any setup where a dedicated anesthesiologist is not present for the full procedure
- Combining four or more major procedures in a single operative session
- Post-operative recovery in an unsupported hotel room without medical check-in protocol
