A nose can look straight from the outside and still feel difficult to breathe through. Although a deviated septum is a familiar cause of nasal obstruction, the support around the nasal valves also matters. These small areas can restrict airflow when they are too narrow or their sidewalls move inward during breathing.
A spreader graft is a narrow strip of cartilage used to support the middle part of the nose and help maintain space at the internal nasal valve. Surgeons may use it during a first rhinoplasty, functional nasal surgery, or revision surgery to protect or restore this area.
Spreader graft rhinoplasty is not necessary for everyone. Its usefulness depends on where the obstruction occurs and which structures need support. Understanding that distinction can help you discuss both breathing and appearance during a consultation.
Key Takeaways
- A spreader graft is usually placed between the upper part of the septum and the upper lateral cartilage on one or both sides.
- It may improve airflow when narrowing of the internal nasal valve or weakness in the middle nasal vault contributes to obstruction.
- Surgeons may use spreader grafts after hump reduction or to reconstruct support altered by earlier surgery.
- Cartilage commonly comes from the septum; ear or rib cartilage may be considered when additional material is needed.
- A graft can affect bridge width and contour, so functional and cosmetic goals should be planned together.
- Spreader grafts do not treat every cause of blockage, and some forms of nasal sidewall collapse need other techniques.
What Is a Spreader Graft?
A spreader graft is a shaped piece of cartilage that acts as an internal support. It helps hold the upper side cartilages of the nose in a suitable relationship to the septum, the wall dividing the two nasal passages.
The term “spreader” describes its role in creating or maintaining space. When the middle third of the nose is too narrow, a carefully placed graft can move the upper lateral cartilage slightly away from the septum while providing support.
The graft is commonly made from the patient’s own cartilage. It stays beneath the nasal tissues rather than sitting on the skin, although it can influence the external contour.
For patients considering rhinoplasty in Toronto, this is one example of how a surgical plan may include supporting the nose as well as changing its shape.
Where Is a Spreader Graft Placed?
The nose has a bony upper portion, a cartilage-supported middle portion, and a more flexible tip. The middle portion is often called the middle vault.
Three structures are particularly relevant to spreader graft placement:
- The septum: the central partition inside the nose, made of cartilage and bone.
- The upper lateral cartilages: paired cartilages that help form the sides of the middle vault.
- The internal nasal valve: a narrow airflow region where the septum and upper lateral cartilage are important boundaries.
A spreader graft is typically positioned lengthwise between the upper edge of the septal cartilage and an upper lateral cartilage. Depending on the anatomy, the surgeon may place a graft on one side or both.
Placement is tailored to the problem. Supporting a crooked middle vault may require a different arrangement from widening a relatively symmetrical but narrow valve area.
What Is the Internal Nasal Valve?
The internal nasal valve is one of the narrowest regions of the nasal airway. Its size and support influence how easily air passes through the nose.
A valve can restrict breathing in two main ways. It may be narrow even when the nose is at rest, or a weak sidewall may move inward as you breathe in. Some patients have a combination of these problems.
This helps explain why a straight septum does not always mean comfortable nasal breathing. Correcting the central partition may leave another site of obstruction untreated.
The American Academy of Otolaryngology–Head and Neck Surgery recognises nasal valve dysfunction as a distinct cause of obstruction that requires clinical assessment. Symptoms and photographs alone cannot reliably identify exactly which structures need treatment.
How Can a Spreader Graft Improve Breathing?
When the internal nasal valve is narrowed near the upper septum, a spreader graft can help preserve or increase the space available for airflow. It may also stabilise the relationship between the septum and upper lateral cartilage.
This support can be useful when the middle vault is naturally narrow, has been injured, or has lost support after surgery. It can also be planned during rhinoplasty to reduce the risk of narrowing after the bridge is reshaped.
However, increasing space beside the septum does not necessarily strengthen every part of the nasal sidewall. A review of spreader grafts and their limitations explains that classic spreader grafts may not adequately address collapse caused by a weak lateral wall. Additional support, such as a different cartilage graft or a suture technique, may be needed.
A clinical study of functional rhinoplasty with spreader grafting reported improvements in airway measurements and patient-reported breathing. Other procedures, including septal and turbinate surgery, were also used, so the findings should not be interpreted as a guarantee or as proof that a spreader graft alone will solve every obstruction.
When Are Spreader Grafts Used in Rhinoplasty?
A Narrow Middle Vault
Some noses have a naturally narrow middle third. If examination shows that this contributes to internal nasal valve obstruction, a spreader graft may help create a more suitable width and provide support.
A narrow-looking nose does not automatically require grafting. The surgeon must relate its appearance to the internal anatomy and the patient’s symptoms.
Dorsal Hump Reduction
Reducing a hump can change the connection between the septum and upper lateral cartilages. In some operations, that area needs reconstruction to maintain bridge contour and protect the airway.
Spreader grafts are one way to provide that support. They may be used preventively even when breathing was comfortable before surgery. Other techniques can also be appropriate, depending on the planned changes and the structures being preserved.
A Crooked Nose or Deviated Upper Septum
A spreader graft can reinforce the cartilaginous middle vault as part of straightening a crooked nose. It may help maintain alignment after the surgeon corrects a deviation.
It does not, by itself, correct every deviation. The nasal bones, lower septum, tip, and other structures may also need attention.
Functional Rhinoplasty
Functional rhinoplasty aims to improve nasal structure for breathing. A spreader graft may be one component when the examination identifies an internal valve problem.
The operation may also involve septoplasty, treatment of enlarged turbinates, or support for another part of the nasal valve. Each component should address a finding from the assessment.
Are Spreader Grafts Used in Revision Rhinoplasty?
Yes. Previous surgery can alter the cartilage and connections that support the middle vault. Hump reduction, removal of cartilage, or subsequent healing may leave the valve area narrower or less stable.
Patients seeking revision rhinoplasty in Toronto may therefore need reconstruction as well as a change in appearance. Spreader grafts can be considered when the upper septum and middle vault need additional support or separation.
Revision surgery also brings different planning challenges. Scar tissue can obscure or restrict structures, and the septum may no longer contain enough suitable cartilage for a new graft. Previous operative records can help the surgeon understand what was changed.
Not every breathing problem after rhinoplasty means the middle vault has collapsed. Swelling, scar tissue, septal deviation, inflammation, or obstruction elsewhere may explain the symptoms. Identifying the cause comes before choosing the graft.
Where Does the Cartilage Come From?
The best source depends on the amount, shape, and strength of cartilage needed, as well as what remains available.
| Cartilage source | Why it may be considered | What to discuss |
|---|---|---|
| Septum | Often provides relatively straight cartilage within the nose | Whether sufficient cartilage can be taken while preserving septal support |
| Ear | Can provide material when septal cartilage is limited | Whether its natural curvature suits the required graft and what harvesting involves |
| Rib | Can supply more cartilage for substantial reconstruction | The extent of reconstruction and the additional donor-site considerations |
Septal cartilage is often suitable for a primary procedure. In a revision case, previous surgery may have reduced the available supply, making another source necessary.
Dr. Rival’s case of septorhinoplasty with rib graft reconstruction illustrates the broader role of cartilage in rebuilding a collapsed bridge and addressing a deviated septum. The source and configuration of grafts in your own operation would depend on your anatomy.
Can a Spreader Graft Change How the Nose Looks?
Yes. Supporting the inside of the nose can affect its outside shape.
Spreader grafts may help create smoother lines along the bridge, reinforce a straighter middle vault, or restore an area that looks pinched. They can also help prevent an inverted-V deformity, a contour change associated with loss of middle-vault support beneath the nasal bones.
The cosmetic effect should be discussed before surgery. A functional improvement may involve adding width to an area that was too narrow, and that can change the frontal view even if the side profile changes little.
Do Spreader Grafts Make the Nose Wider?
They can widen the middle third because they add cartilage between existing structures. How noticeable that becomes depends on the starting shape, graft dimensions, placement, skin thickness, and other surgical changes.
The aim is controlled support that fits the overall nose. However, it would be misleading to promise that width will never change or that the graft will always be completely imperceptible.
A published review of 100 endonasal spreader graft cases documented visible graft edges in some patients, reinforcing the importance of precise placement. Ask your surgeon how the proposed support may affect your bridge and which aesthetic trade-offs apply to you.
Spreader Graft vs Septoplasty: What Is the Difference?
Septoplasty and spreader grafting address different structural problems, although they may be performed together.
| Treatment | Main structure addressed | Main purpose |
|---|---|---|
| Septoplasty | The septum dividing the nasal passages | Correct a deviation contributing to obstruction |
| Spreader grafting | The relationship between the upper septum and upper lateral cartilage | Support or widen the internal valve region and middle vault |
| Other valve-support techniques | The specific weak or collapsing part of the nasal sidewall | Improve support where spreader grafting alone may be insufficient |
Some patients need septoplasty without valve repair. Others need valve treatment, or a combination of procedures. Enlarged turbinates, which are structures along the inside walls of the nose, can contribute to obstruction as well.
The AAO-HNS position statement explains that septoplasty and turbinate surgery can complement nasal valve repair, but they do not replace treatment of a valve problem when one is present. This is why a complete examination matters more than assuming that all nasal blockage comes from the septum.
Are Spreader Grafts Always Necessary for Breathing Problems?
No. A spreader graft is useful only when its structural effect matches the cause of obstruction.
Allergies or inflammation may need medical treatment. An obstructing septal deviation may call for septoplasty. A weak sidewall may need a different form of support, and temporary postoperative swelling requires assessment in the context of healing.
In selected noses, the surgeon may use a spreader flap, folding suitable existing upper lateral cartilage to help support the middle vault rather than adding a separate cartilage strip. This also has anatomical limitations and is not interchangeable with a graft in every case.
Ask why a proposed technique fits your particular obstruction and what alternatives were considered. The presence of a graft is not, by itself, evidence that an operation will provide better breathing.
What Should You Expect During Recovery?
Spreader grafting is often part of a larger operation, so recovery depends on the complete surgical plan. Swelling, internal splints, and crusting can temporarily limit airflow even when the underlying support has been improved.
That means comfortable breathing may not be immediate. Follow-up examinations help the surgeon distinguish expected healing from a problem that needs treatment. Our guide to breathing after rhinoplasty explains why symptoms can fluctuate during recovery.
Contact your surgical team about worsening obstruction, increasing pain, fever, or significant bleeding rather than assuming that every change is normal swelling. Ask before surgery whom to contact and what symptoms require urgent assessment.
Also discuss rhinoplasty risks and functional concerns. Grafting does not eliminate the possibility of persistent obstruction, infection, contour irregularities, or a need for further correction.
What to Discuss During Consultation
A consultation with Dr. Richard Rival should connect your symptoms to the structures causing them. Explain whether the blockage affects one side or both, whether it changes with activity, and whether it began after injury or surgery.
Assessment may include the septum, internal and external nasal valves, turbinates, middle-vault width, bridge shape, tip support, and skin thickness. The surgeon also considers how restoring support could change the appearance of the nose.
Useful questions include:
- Is my obstruction related to internal valve narrowing, sidewall collapse, or another cause?
- What would a spreader graft address in my case?
- Would I need septoplasty or another support technique as well?
- Where would the cartilage come from?
- How might grafting affect the width or contour of my bridge?
- How will we assess breathing as healing progresses?
If you have already had surgery, bring any available operative reports and earlier photographs. Our rhinoplasty consultation questions can help you prepare for the wider discussion of expectations, recovery, and risks.
Frequently Asked Questions
What is a spreader graft in rhinoplasty?
It is a strip of cartilage placed inside the nose, usually between the upper septum and an upper lateral cartilage. It can support the middle vault, maintain the internal nasal valve area, and help shape the bridge.
How does a spreader graft improve breathing?
It can create or maintain space near the internal nasal valve and stabilise the adjoining cartilage. It is most useful when narrowing in that area contributes to obstruction. Other causes of blockage may require additional treatment.
Is a spreader graft the same as septoplasty?
No. Septoplasty addresses a deviated septum. Spreader grafting supports the middle vault and internal valve region. Some patients benefit from both, while others need only one or a different form of treatment.
Do spreader grafts make the nose wider?
They can add width to the middle third of the nose. The amount and visibility vary with the graft and the existing anatomy. Your surgeon should explain how the proposed functional correction may affect the frontal appearance.
When are spreader grafts used in rhinoplasty?
They may be used for a narrow middle vault, support after hump reduction, reinforcement during crooked-nose correction, or reconstruction after earlier surgery. The decision depends on the structures affected, rather than the procedure’s name alone.
Where does the cartilage for a spreader graft come from?
The septum is a common source when suitable cartilage is available. Ear or rib cartilage may be considered, particularly in revision surgery. The choice depends on the shape, quantity, and strength required.
Are spreader grafts always needed for breathing problems after rhinoplasty?
No. Swelling, inflammation, septal deviation, enlarged turbinates, scar tissue, and different forms of valve dysfunction can all affect breathing. An examination is needed before deciding whether a spreader graft would help.
Can a spreader graft be used in revision rhinoplasty?
Yes. It may help rebuild a narrowed or weakened middle vault after previous surgery. Revision planning also considers scar tissue, remaining cartilage, and whether other areas of the nose need reconstruction.
The Goal: A Nose That Looks Natural and Breathes Well
Spreader grafts can help when the internal nasal valve and middle vault need support, but they are one part of an individual surgical plan. The right approach depends on the source of obstruction, your cosmetic goals, and any previous surgery.
If you have breathing problems after rhinoplasty or have been told you may need a spreader graft, a consultation with Dr. Richard Rival can help clarify whether grafting, septoplasty, revision surgery, or another treatment is appropriate.
