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.

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.
