Definition
보존 코 성형 (bojon ko seonghyeong, preservation nose surgery) — or preservation rhinoplasty — is a surgical philosophy in which the nose’s native structural components are kept intact rather than excised and reconstructed. Specifically, the osseocartilaginous vault (the fused bone-and-cartilage roof of the nose) is lowered by repositioning rather than by removing tissue. The result is a dorsum that retains its original ligament attachments, skin envelope, and cartilage continuity — three properties that support natural postoperative movement and reduce the scar burden that accumulates after conventional removal-based approaches.
How It Differs from Reduction Rhinoplasty
Conventional reduction rhinoplasty addresses a dorsal hump — an excess curve on the nasal bridge — by surgically removing the offending bone and cartilage, then reassembling the remaining structure with osteotomies (controlled bone cuts) and grafts. This reliably lowers the bridge but severs ligaments, disrupts the skin’s underlying support, and generates scar tissue as the wound heals. That scar tissue gradually stiffens the nose and narrows the surgical options if revision is ever required.
Preservation rhinoplasty addresses the same hump through a different mechanical principle: the dorsum is pushed downward as a continuous unit rather than reduced piece by piece. Two main sub-approaches exist — the “let-down” technique, which lowers the entire nasal pyramid via cartilage modification at the septal base, and the “push-down” technique, which repositions through bony foundation adjustments. Both keep the cartilaginous roof continuous, preserving the ligaments and soft-tissue attachments that give the nose its characteristic movement and tactile quality. The practical difference for patients: a preservation-technique nose tends to feel and move more like an unoperated nose, and retains more anatomical options if secondary surgery is ever needed.
| Feature | Reduction Rhinoplasty | Preservation Rhinoplasty |
|---|---|---|
| Dorsal hump treatment | Excision and rebuild | Repositioning intact vault |
| Ligament disruption | Yes — ligaments severed | Minimal — ligaments retained |
| Scar tissue formation | Higher | Lower |
| Tip mobility post-op | Reduced (scar stiffening) | Better maintained |
| Revision complexity | Higher (scar distortion) | Potentially lower |
| Suitable for revision cases | Yes | Generally no |
| Suitable for severe deviation | Yes | Generally no |
Candidates for Preservation Rhinoplasty
Three anatomical criteria indicate strong candidacy. First, a moderate dorsal hump — large enough to warrant surgery but not so extreme that the repositioning math fails. Second, structurally sound cartilage — the technique depends on intact, elastic cartilage capable of tolerating repositioning without fracturing. Third, primary (first-time) surgery — scar tissue from prior rhinoplasty disrupts the tissue planes that preservation technique relies on, making it unsuitable for most revision cases.
Patients with straight or minimally deviated septums (the central cartilage dividing the nasal airway) are better candidates than those with significant septal deviation, because severe deviation requires direct cartilage manipulation that conflicts with the preservation philosophy.
Often a good candidate
- Moderate dorsal hump, primary (first) rhinoplasty
- Structurally intact and elastic nasal cartilage
- Straight or minimally deviated septum
- Patient prioritizes natural postoperative movement and texture
Should reconsider or wait
- Large or complex dorsal hump requiring significant volume reduction
- Mild pre-existing septal deviation — surgeon assessment required
- Thin or fragile cartilage identified on clinical examination
Not a suitable candidate
- Revision rhinoplasty with existing scar tissue
- Severely deviated septum requiring structural reconstruction
- Significant prior nasal trauma affecting cartilage integrity
Limitations
Preservation rhinoplasty is not a universal upgrade over conventional technique — it is a tool suited to specific anatomy. The repositioning mechanics require a minimum hump height; very small humps may not generate enough structural movement to achieve the intended result. Very large humps may exceed the range the technique can address without adding grafts, at which point a hybrid or structural approach may be more reliable.
Surgeon training is the other constraint. The technique demands precise understanding of nasal anatomy and tissue planes that differ from conventional reduction training. KSPRS board certification¹ confirms a surgeon has completed a four-year plastic surgery residency,² but preservation rhinoplasty is an advanced subspecialty skill — ask specifically about a surgeon’s training and case volume in this technique before proceeding.³

Is preservation rhinoplasty available in Korea?
Yes — preservation technique has been adopted widely among KSPRS-certified rhinoplasty specialists since approximately 2018. When researching a Korean surgeon, ask directly whether they perform preservation rhinoplasty and what proportion of their primary rhinoplasty cases use this approach. Surgeons trained specifically in preservation technique can describe their approach in detail.
Is preservation rhinoplasty better than traditional rhinoplasty?
For appropriate candidates (moderate hump, good cartilage, primary surgery), preservation technique offers advantages: less scar tissue formation, maintained tip mobility, and potentially simpler revision if ever needed. For complex cases, deviated septums, or revision surgery, structural techniques may be more appropriate. Neither is universally better — anatomy and surgeon training determine the right approach.
Does preservation rhinoplasty cost more in Korea?
Preservation rhinoplasty requires more advanced training and surgical precision, and may command a slight premium at surgeons specifically trained in the technique. In practice, pricing at Korean clinics is based on procedure scope rather than technique label — ask your surgeon how they categorize it in their fee structure.
