The two main philosophies of modern rhinoplasty differ fundamentally in how the dorsum (nasal bridge) is reshaped. This guide explains each approach so you can make an informed decision.
Dorsal preservation rhinoplasty (DPR) is a modern technique in which the natural dorsum is kept intact and lowered as a single unit. Instead of removing the bridge and rebuilding it, the surgeon performs precise septal and bony maneuvers from below to descend the existing bridge. The patient's original dorsal aesthetic lines, ligamentous attachments and skin envelope are preserved.
Preservation comes in several forms: push-down (impacting the bony pyramid), let-down (removing a precise wedge of lateral nasal wall), and septal-resection variants — low septal resection (LSR) and high septal resection (HSR).
Structural rhinoplasty — also called classical or component rhinoplasty — removes the dorsal hump (component reduction of bone and cartilage), then rebuilds and stabilizes the bridge using cartilage grafts, osteotomies and suture techniques. It has been the dominant approach for decades and remains highly effective in experienced hands. However, because the bridge is opened and reconstructed, there is a small risk of an "open-roof" deformity, dorsal irregularities, or visible graft edges over time.
| Factor | Preservation | Structural |
|---|---|---|
| Dorsum handling | Preserved & lowered as a unit | Removed & rebuilt |
| Aesthetic dorsal lines | Original lines kept intact | Reconstructed surgically |
| Open-roof risk | None — dorsum never opened | Possible — requires closure |
| Visible irregularities | Less common | Possible (graft edges, callus) |
| Cartilage grafts | Often minimal or none | Frequently used for support |
| Skin envelope | Preserved (less swelling) | More disrupted |
| Best candidates | Most primary cases | Complex revisions, severe deformity |
| Approach | Typically closed (no scar) | Open or closed |
Most primary rhinoplasty patients are candidates for the preservation approach. Specifically:
Structural rhinoplasty remains the better choice in selected scenarios:
The boundary between the two philosophies continues to evolve. Many surgeons — including Dr. Erdal — combine preservation principles with selective structural maneuvers to optimize each case.
"Preservation/structural" describes what is done to the dorsum. "Closed/open" describes where the incisions are placed. They are independent decisions:
Dr. Erdal performs preservation rhinoplasty almost exclusively via the closed approach, combining the technique-level advantages of preservation with the cosmetic advantage of no external scar.
Preservation rhinoplasty: Splint off at day 7. Most patients fly home within 7–10 days. Socially presentable at 2–3 weeks. Major swelling resolves by month 3 because the skin envelope is less disrupted. Final result at 6–12 months.
Structural rhinoplasty: Splint off at 7–10 days. Residual swelling may persist longer. Tip swelling can take 12–18 months to fully resolve, particularly in open-approach cases.
For a detailed week-by-week breakdown, see our complete rhinoplasty recovery timeline.
Both techniques have comparable safety profiles when performed by an experienced surgeon. Preservation involves less tissue disruption and avoids the open-roof step, which may reduce certain long-term irregularity risks.
The cost difference is typically minimal and depends more on case complexity than technique choice. See our rhinoplasty cost guide for detailed pricing information.
Yes. The let-down technique combined with appropriate septal resection can lower large humps reliably. Dr. Erdal has published peer-reviewed papers on managing the bony and cartilaginous components in this scenario.
Often, but not always. Even in preservation rhinoplasty, small cartilage grafts may be used selectively for tip refinement or sidewall support. The difference is that grafts are not needed to rebuild the dorsum itself.
Preservation rhinoplasty is not a universal substitute for structural technique. Specific anatomic conditions favour preservation; others favour structural. The decision is anatomic, not philosophical:
Recovery profile differs between preservation and structural rhinoplasty in measurable ways. Both approaches have legitimate roles; understanding the recovery trade-offs helps inform technique selection where anatomy permits either:
| Recovery aspect | Preservation | Structural |
|---|---|---|
| Operating time | 2-3 hours typical | 2.5-3.5 hours typical |
| Post-op edema (face) | Often less — limited middle vault disruption | More substantial — middle vault reconstruction |
| Tip swelling | Resolves 6-9 months typical | Resolves 9-12+ months |
| Bruising around eyes | Often less — reduced osteotomy disruption | More with traditional component reduction |
| Splint duration | 5-7 days typical | 5-7 days typical |
| Activity progression | Slightly faster typical | Standard timeline |
| Return to work (sedentary) | 1-2 weeks | 1-2 weeks |
| Return to gym (light) | Week 2-3 | Week 2-3 |
| Full activity clearance | Week 6-8 | Week 6-8 |
| Final result emergence | 6-9 months typical | 9-12+ months |
| Revision risk profile | Lower for inverted-V; higher for hump recurrence in marginal cases | Higher for inverted-V; lower for under-correction |
The differences are real but not dramatic. For appropriately selected anatomy, preservation rhinoplasty produces faster swelling resolution and earlier final result visibility. For complex anatomy that benefits from structural approach, the recovery is similar to traditional rhinoplasty with predictable outcomes.
The single most important factor in technique selection is having a surgeon who can perform both approaches and selects based on your anatomy rather than their habit. Surgeons fall into three categories:
Specific answers reveal the surgeon's profile. A surgeon who reports 90%+ preservation or 90%+ structural is operating with limited toolkit. A surgeon who reports a mix (e.g., 50/50 or 60/40 either direction) and explains the selection criteria is operating with full toolkit selection capability.
Depends on your anatomy. Strong preservation candidates: mild-to-moderate humps (under 5-6mm), smooth dorsal aesthetic line worth preserving, compatible septal anatomy, ethnic noses, patients prioritising natural appearance. Weaker candidates: large humps, significant asymmetry, saddle nose, severe septal deviation, revision after over-reduction, calcified bony pyramid in older patients. The decision is anatomic, not philosophical. A surgeon who offers only preservation or only structural is selecting based on their toolkit rather than your anatomy.
Push-down technique: typically 3-5 mm reduction, suitable for mild-to-moderate humps. Let-down technique: 4-7 mm reduction, suitable for moderate-to-large humps. Beyond that range, structural component reduction is technically more reliable. Mixed approaches (push-down with limited cap reduction) can extend the range slightly. The reduction limit reflects mechanical realities of mobilising the dorsum into the resected septal space — beyond a certain depth, the geometry doesn't permit clean preservation.
Yes — when executed in suitable anatomy. The dorsal aesthetic line existing pre-operatively is maintained because the dorsal segment (skin, ULC, dorsal septum, bony cap) is descended into a deeper plane rather than disrupted. The preserved line shows visible benefit: smoother continuous reflexes from radix to tip, no inverted-V step at the keystone, more 'natural' appearance. In structural rhinoplasty, the dorsal line must be reconstructed through closing osteotomies and spreader graft placement — successful when well-executed but a different mechanism.
Often, but not dramatically. Faster swelling resolution typical (tip swelling 6-9 months vs 9-12+ for structural). Less bruising around eyes typical due to reduced osteotomy disruption. Splint duration similar (5-7 days). Activity progression similar. Final result emergence typically 3-6 months earlier than structural in suitable cases. The differences are real but the patient should not expect dramatic recovery time differences — both techniques require respect for the structural healing timeline.
Generally not — most practices charge similar fees for primary rhinoplasty regardless of technique. Preservation rhinoplasty does not require expensive cartilage harvesting or complex graft work in primary cases; structural rhinoplasty includes spreader grafts and osteotomies but uses septal cartilage. Cost differences typically come from surgeon experience and credential level, not technique selection. Both approaches priced in the €4,500-€6,500 range at this practice for primary cases.
Yes — combined preservation septorhinoplasty is performed routinely. The septal strip removal required for push-down or let-down naturally addresses anterior septal pathology. Posterior septal deviation may require additional septoplasty work. Internal valve assessment and management are standard. Combined operation typically 2.5-3.5 hours; recovery similar to preservation rhinoplasty alone with some additional initial breathing concerns due to packing or splints.
