Our methodology.
DEEPPLANE™ is built on transparency. Every surgeon profile, every ranking, and every piece of educational content follows a documented, repeatable process. This page explains how we collect data, verify credentials, generate content, and maintain quality across the platform.
Expert Opinion on Safety
"Deep plane facelift is extremely safe in experienced hands. The technique actually has a lower rate of skin complications because we maintain the blood supply. The key is choosing a surgeon who performs this procedure regularly."
Dr. Yakup Duman
Board-Certified Plastic Surgeon, Medical Advisor
What we check — and what we don’t
DEEPPLANE™ is a compilation of public information about deep plane facelift surgeons. Most of it we gathered; very little of it we confirmed. This table says which is which, and it is generated from the same database that serves the directory, so it cannot drift away from the pages it describes.
Reusable with attribution (CC BY 4.0). Machine-readable at /api/v1/stats.json.
| What | How many | How it got there |
|---|---|---|
| Surgeons listed | 1,411 | Across 70 countries. 1,377 were compiled from public sources without us contacting the surgeon; 486 of those came from scraping rather than a directory listing or a submission. |
| DEEPPLANE™-verified | 35 | Means one specific thing: the surgeon claimed the profile and we confirmed they control the practice email domain. It is not a check of the surgeon. |
| Board certification listed | 1,010 | Self-reported — taken from the surgeon's or clinic's own published text, an NPI taxonomy code, or a model reading a search result. We do not query the issuing board. |
| Credentials confirmed with the issuing body | 0 | Our published credential registry reports this figure itself. It has always been zero. |
| Profiles with a documented case volume | 0 | We hold no case-volume data for any surgeon. Ask for it directly in your consultation. |
| Facility accreditation on file | — | No such field exists in our data. Where a page names JCI or an equivalent, it is describing the hospital, not something we verified. |
| Per-field source records | 9 | The provenance engine — source URL, capture time, content hash per field — is in development. 9 records exist platform-wide, so treat a profile field as the surgeon's own published material unless a page says otherwise. |
| Before / after images published | 2,543 | Collected from public clinic websites, Instagram and YouTube. 54 carry a signed patient consent on file. We do not authenticate images, and no image here has been checked against a surgeon's records. |
| Profiles showing a fee | 21 | Of 1,411 listed profiles. 10 carry a fee the surgeon published himself; the rest of the figures we hold are bands this platform generated, and we do not show those beside a named doctor. Where a profile is blank, we could not establish a fee — it is not a claim that the surgeon is expensive or cheap. |
| Patient reviews collected by us | 0 | Star ratings on profiles come from Google, are shown with their source, and are not verified as coming from patients — by Google or by us. |
| Educational pages with a recorded medical review | 1 of 164 | Pages are written and edited in-house and read by Dr. Yakup Duman, Specialist in Plastic, Reconstructive and Aesthetic Surgery. There is no standing review panel; per-page review status is published as it is recorded. |
| Newsletter subscribers | 12 | Listed because it was published as “10,000+” until 2026-08-01, and a corrections page that skips its own embarrassing number is not a corrections page. |
Changing on 1 September 2026. From that date a verified badge requires the DEEPPLANE™ badge to be live on the surgeon’s own website, and the figure above falls to 12. The table reads the same gate the profile pages do, so it changes on its own rather than waiting for anyone to remember. We are publishing the date rather than letting the number move quietly.
How We Collect Surgeon Data
Our data pipeline aggregates information from multiple authoritative sources to build the most complete picture of each surgeon's practice:
- Google Business Profiles — We pull practice locations, contact details, opening hours and public reviews from Google Business listings. Google does not verify that reviewers were patients, and neither do we.
- Medical Registries — Board certifications are recorded as the surgeon or clinic publishes them, or inferred from an NPI taxonomy code. We do not query GMC, ABPS, the Turkish MOH or any other register, and we hold no licence-status data.
- Instagram & Social Media — Surgeon portfolios, before/after imagery, and patient engagement are tracked from public Instagram profiles and professional websites.
- Professional Societies — Membership in ISAPS, AAFPRS, BAAPS, SOFCEP, and other recognized surgical societies is cross-referenced for each listing.
What Actually Happens To A Profile
A profile passes through up to four states. Most never leave the first — 1,541 of 1,572 were compiled without us contacting the surgeon at all:
1 · Compiled
Built from public sources — clinic websites, professional-society directories, Google Business listings and, where available, NPI records. No document is requested and none is checked.
2 · Claimed
The surgeon claims the profile and proves control of the practice email domain. That is the whole of it: we do not contact the issuing board, so the certification shown stays self-reported.
3 · Badged
From 1 September 2026, keeping the badge requires a DEEPPLANE™ link live on the surgeon's own website. Ten profiles carry one today.
4 · Corrected
Anyone — surgeon, patient or reader — can ask us to change or remove something. We do not monitor licence status or disciplinary actions, so if one changes, the only way we learn is if someone tells us.
Content Generation
Educational articles, surgeon bios, and comparison pages are produced through an AI-assisted pipeline with strict medical oversight:
- AI-Assisted Drafting — Initial content is generated using large language models trained on peer-reviewed medical literature and clinical guidelines.
- Medical Expert Review — Pages are written and edited in-house to the standard our medical reviewer sets, and he is named as reviewer-of-record on each one. A separately recorded per-page review signature is rarer; the live count is in the table on this page. Every other page is written and edited in-house and carries our medical reviewer as reviewer-of-record for the editorial standard, not as a per-page sign-off.
- 23 Quality Rules — Content must pass 23 automated checks including hedged language requirements, citation minimums, readability scores, and medical disclaimer presence.
- Attribution & Transparency — All claims are attributed to published research. We never present opinion as fact, and all content carries clear medical disclaimers.
Data Freshness
Outdated information erodes trust. We maintain freshness through three update cycles:
Weekly
Review data and ratings are refreshed from Google Business and other review platforms every 7 days.
Real-Time
Directory counts are a live query. We do not receive licence or disciplinary feeds, so nothing changes automatically when a surgeon's standing does — a correction reaches us because a person sends it.
On request
There is no fixed editorial review cycle. Each learn page shows its own last-modified date, and we correct pages when someone tells us they are wrong.
Editorial Independence
Patient trust requires editorial integrity. Our commitment:
- -Rankings are algorithmically determined. Listings are sorted by verification tier, then subscription start date, then surname. Review volume, rating and our authority score are displayed but do not enter the sort. No position is for sale.
- -Paid features are cosmetic. Premium subscriptions unlock profile enhancements (photo galleries, direct WhatsApp contact, featured placement labels) but never alter ranking algorithms.
- -Content is editorially independent. Our medical reviewer and editorial team operate independently from the business team. No surgeon can influence the content of educational articles.
- -Methodology is public. This page itself is our commitment to transparency. If our process changes, this page is updated.
- -Conflict of interest disclosure. Our primary medical reviewer, Dr. Yakup Duman, is also a listed and ranked surgeon on the platform. His editorial review covers medical accuracy of educational content; he does not participate in ranking decisions that affect his own profile. We are actively expanding our editorial board to include independent reviewers without platform listings.
The Patient-Ordered Verification Dossier
A patient may commission independent verification research on any surgeon — listed on DEEPPLANE or not — for a flat fee paid by the patient, never by the surgeon. Because the decision-maker pays, the referee answers to her alone. These rules are published before any dossier is sold, and every dossier is bound by them:
- -The fee buys research, never a result. Permitted conclusions are: credentials verified; partially verified; we could not verify enough — treat that as a signal; or the record argues against proceeding. All cost the same and none is refunded for being unwelcome.
- -The no-influence wall. A surgeon cannot commission, preview, soften or suppress a dossier, and is not told one exists — including surgeons who pay DEEPPLANE for leads. A dossier softened under commercial pressure would end this product; that is the standard it is held to.
- -"We could not verify" is a finding. Every dossier ends with an item-by-item list of what could not be verified. An unverifiable claim is reported as exactly that — never omitted, never rounded up to verified.
- -Private to the patient; email used once. The report is delivered on a private link only the patient holds. Her email receives the payment receipt and one delivery notice, and is never added to any mailing list. The surgeon’s public DEEPPLANE profile does not change because a dossier was ordered.
Canonical Data Facts — Source provenance
The data_facts canonical registry is how we intend every public-facing profile field to trace to its source. It is partially built, not universal: our per-field provenance table holds 6 records platform-wide. Where a profile field has no record, treat it as the surgeon's or clinic's own published material. When a field does carry one, it holds:
- -Sources array: kind (npi, openalex, orcid, hhs_leie, pubmed, wikidata, etc.), source URL, capturedAt timestamp, sha256 content hash, source confidence.
- -Verification level:
provisional(single source, tier 2-3) /verified(2+ sources or single tier-1) /gold(3+ sources or tier-1 + corroborator). - -Quality score (0–1) computed from source count, max-tier bonus, recency, and agreement ratio. Display gate (public_gold / public_verified / public_provisional / admin_only / quarantine) is set algorithmically from this score.
- -Refresh cycle: per-field freshness clock, defined but not yet running site-wide. Where a connector is wired, a cron re-invokes it and detects drift by hash diff; most fields have no connector and no clock.
Source tier preference
- Tier 1Government registries (NPI/NPPES — npiregistry.cms.hhs.gov), specialty boards (ABFPRS, ABPS, UK GMC), federal sanctions list (HHS OIG LEIE), FDA adverse events (openFDA), patent inventor registries (USPTO).
- Tier 2Academic registries (PubMed, OpenAlex, CrossRef, ORCID), professional societies (ISAPS, AAFPRS, ASAPS, ABOHNS), accreditation bodies (WDOMS, JCI).
- Tier 3Aggregators with public APIs (Google Places, Wikidata, Google Knowledge Graph).
- Tier 4Social platforms (Instagram, YouTube). Used only as last-mile signals (follower count, content sample) — never sole sources for clinical credentials.
When two sources disagree, the higher-tier source wins; recency breaks ties. Conflicts beyond a threshold flip a fact to admin_only display gate (hidden from public view) until the conflict resolves via additional source agreement.
Verification ladder
- GoldA fact whose
sources[]contains ≥2 independent tier-1 contributors (e.g. NPI taxonomy specialty agreeing with ABFPRS diplomate status agreeing with the surgeon's own claim). Highest verification grade; rendered with the "Gold" badge on profiles. - VerifiedBacked by at least one tier-1 source OR two tier-2 sources. Public display.
- ProvisionalSingle source, recent enough, no conflict. Public display with a "provisional" marker.
The reconciliation engine recomputes the level every time a connector adds a new source, so a provisional fact can be promoted to verified or gold as additional registries corroborate it. The aggregate breakdown by tier is published as part of our annual State of Deep Plane Facelift Report.
Public auditable surface
Every surgeon's canonical facts are exposed as JSON at /api/v1/surgeons/{slug}/facts.json — journalists, regulators, surgeons, and AI crawlers can independently verify each claim by following the sources[].url back to the originating registry.
