Preservation or structural rhinoplasty: what the difference really means.

The short version of a long debate

For decades, rhinoplasty meant cutting the hump away and then rebuilding what the cut removed. That is the logic behind structural rhinoplasty: open the nose, reshape the framework, and reinforce it with cartilage grafts so the result holds over time.

Preservation rhinoplasty reversed the order of operations. Instead of removing the roof of the nose and reconstructing it, the surgeon lowers the entire dorsal unit from below, keeping the keystone area, the natural light reflexes and much of the soft tissue envelope untouched.

Both philosophies produce excellent noses in experienced hands. Both produce problems when applied to the wrong anatomy. The useful question is not which technique wins, but which parts of your nose deserve preservation and which parts need structure.

What preservation rhinoplasty actually preserves

Three things:

1. The dorsal line. The bony and cartilaginous bridge stays in one piece. It is lowered as a unit after cartilage or bone is removed at the base of the nose.
2. The ligaments and soft tissue. The scroll ligament and the tip ligaments can be left intact or repositioned, which tends to reduce swelling and keep tip support.
3. The internal valve area. Because the mucosa under the dorsum is not opened, the middle vault keeps its original width, which matters for breathing.

The two classic maneuvers are the push down, where the nasal pyramid slides between the bones of the face, and the let down, where a small strip of bone is removed at the base before the pyramid is lowered. The choice depends on hump size, bone thickness and the shape of the nasal base. You can read a fuller explanation on the preservation rhinoplasty page.

What structural rhinoplasty actually builds

Structural technique is the language of reconstruction. The surgeon exposes the framework, reduces what is excessive, and then adds support where the nose is weak:

• Spreader grafts to reopen the internal valve after hump removal.
• Columellar strut or septal extension graft to set tip projection and rotation.
• Lateral crural support for the alar cartilages when they are weak or malpositioned.
• Rib or ear cartilage when the septum does not offer enough material, which is common in revision cases.

This is the approach that saves noses with severe deviation, collapsed valves, short noses, thick skin with poor definition and previous surgeries. Most revision rhinoplasty work is structural by necessity, because the first operation already consumed the natural support.

Side by side comparison

Aspect	Preservation	Structural
Dorsum	Lowered as a unit, kept intact	Removed and rebuilt
Typical grafts	Few, mostly at the tip	Spreaders, struts, septal extension, rib or ear
Internal valve	Usually untouched	Reconstructed with spreaders
Best suited for	Straight or slightly convex dorsum, good bone quality, patients who like their own bridge	Severe deviation, collapsed valves, thick skin, short nose, previous surgery
Limits	Not ideal for very wide or markedly asymmetric dorsum without adjustments	More dissection, more swelling in the early weeks
Risk to watch	Hump recurrence if the base work is insufficient	Dorsal irregularities and graft visibility over time
Operative time	Often shorter	Often longer, especially with rib

The table describes tendencies, not rules. Anatomy decides. So does the surgeon's training.

The hybrid approach: most noses need both

In practice, the division is artificial. A nose can have a dorsum that deserves preservation and a tip that needs a septal extension graft. Another can need a modified dorsal approach with partial preservation of the cartilaginous vault plus structural support below.

This is where the surgeon's published work matters. Dr. Sella coauthored Expanding Indications to Dorsal Preservation Rhinoplasty in Facial Plastic Surgery Clinics of North America in 2025, together with earlier papers on the Brazilian approach to dorsum preservation and on avoiding complications in preservation cases. The common theme of those articles is pragmatic: widen the indications where the evidence allows, and convert or combine techniques when the anatomy says so.

The practical consequence for you as a patient is simple. The plan presented in consultation should explain what will be preserved, what will be reinforced, and why.

How ultrasound and ultrasonic instruments change the decision

Two tools make the choice more objective.

High frequency dermatologic ultrasound before surgery measures skin thickness, identifies old fillers, shows previous grafts, detects bone irregularities and maps columellar vascularization. Thick skin changes what definition is realistic. Hidden permanent filler changes the entire plan. In the clinic in Maringa, this exam is performed by Dr. Nubia Goedert Soares Sella, a radiologist with training in aesthetic medicine.

Piezoelectric instruments allow bone to be sculpted and cut without injuring the mucosa and soft tissue around it. That precision supports preservation maneuvers such as the let down, and also refines bone work in structural cases. More detail on ultrasonic rhinoplasty is available on the dedicated page.

During surgery, a projectometer is used to measure projection and rotation instead of relying only on visual impression.

What each route means for your recovery

The postoperative protocol is largely the same. External splint for about seven days, taping for another week, no nose blowing, saline irrigation, head elevated at thirty degrees for at least ten days, ice in the first two weeks, no glasses for four weeks, exercise after fifteen days, sun and pool only after one month, sunscreen for three months.

Differences are a matter of degree. Preservation cases often show less dorsal swelling early on because the soft tissue envelope was not fully elevated. Structural cases with rib cartilage usually take longer in the operating room and involve a chest donor site. In both, the definitive result appears between six and twelve months, and up to eighteen months in thick skin or revision cases.

Revision rates reported in the general rhinoplasty literature range from roughly five to fifteen percent, and any reassessment is made only after twelve months.

Questions worth asking before you fly

If you are planning surgery abroad, the technique discussion should happen before boarding. A teleconsultation allows that. Useful questions:

• Which parts of my dorsum do you intend to preserve?
• If preservation is not possible during surgery, what is the alternative plan?
• Which grafts are likely, and where will the cartilage come from?
• How does my skin thickness affect what is realistic?
• What does the digital simulation represent? Simulations are a communication tool with roughly sixty to seventy percent similarity to the final result.

International patients and Brazilians living abroad are seen regularly in Maringa. The usual sequence is teleconsultation first, preoperative tests in your home city, arrival one or two days before surgery, about seven days in the city until the splint is removed, then follow up at one, three, six and twelve months in person or online. Practical details are on the international patients page.

When to see Dr. Sella

A consultation lasts about one hour and includes history, internal examination of the nose, standardized photographs, digital simulation, nasal ultrasound when indicated and a written postoperative timeline. Only after that evaluation can anyone say whether preservation, structural technique or a combination fits your anatomy and your goals.
