The nasal septum is often discussed in relation to breathing, but it also plays an important structural role in rhinoplasty.
Located inside the nose, the septum helps separate the two nasal passages and contributes to the support of the nasal bridge and tip.
Septal cartilage can also be an important source of graft material during rhinoplasty.
For these reasons, evaluating the septum is not only important for patients with breathing problems. Its shape, strength, and remaining cartilage can directly influence how rhinoplasty is planned.
What Is the Nasal Septum?
The nasal septum is the internal wall that divides the left and right sides of the nasal cavity.
It consists of cartilage and bone.
The front portion contains septal cartilage, which contributes to the structural framework of the nose. This cartilage can provide support while also serving as a useful graft material during rhinoplasty.
The condition of the septum can therefore affect both nasal function and external nasal shape.
Why Is Septal Cartilage Used in Rhinoplasty?
Septal cartilage is located within the surgical area and can often be harvested without requiring a separate incision elsewhere on the body.
It can be used for several purposes depending on the operation, including supporting or reshaping parts of the nasal tip.
For patients undergoing primary rhinoplasty with adequate septal cartilage, it may provide enough material for the planned structural changes.
However, the amount and strength of available cartilage vary between individuals.
Is Septal Cartilage Always Enough?
No.
Some patients naturally have relatively limited or weak septal cartilage.
Others may require more structural support than their septum can provide.
The situation is particularly relevant in revision rhinoplasty. If septal cartilage was removed or weakened during a previous operation, there may not be enough remaining cartilage for reconstruction.
In these cases, another cartilage source may need to be considered.
Why Does Previous Septal Surgery Matter?
A history of septoplasty or previous rhinoplasty can significantly affect the surgical plan.
Septal surgery may have removed part of the cartilage that would otherwise be available for grafting.
The remaining septum may also differ in strength or shape.
This does not mean that rhinoplasty cannot be performed after septal surgery. It means that the surgeon needs to understand what cartilage and structural support remain before deciding which technique or material is appropriate.
Can a Deviated Septum Affect the Shape of the Nose?
Yes.
A deviated septum can sometimes contribute to external nasal deviation, although not every crooked-looking nose is caused by the septum alone.
In a crooked nose, the septum, nasal bones, and cartilage framework may need to be evaluated together.
The nasal bones, upper lateral cartilages, tip cartilages, and surrounding facial asymmetry can also contribute.
When both internal and external structures are deviated, correcting only the visible portion of the nose may not adequately address the underlying structural problem.
For this reason, the septum should be evaluated as part of the overall nasal framework.
Is Septal Deviation Always Corrected During Rhinoplasty?
Not necessarily.
The surgical plan depends on the degree and location of the deviation, symptoms, external nasal shape, and the objectives of surgery.
A patient may have septal deviation without significant breathing symptoms, while another patient may have functional concerns that require additional evaluation.
Rhinoplasty should therefore not automatically be considered the same procedure as functional septal surgery.
Each component needs to be assessed according to the individual patient’s anatomy and symptoms.
What Happens When the Septum Is Weak?
The septum contributes to the central support of the nose.
When important structural portions are weak or have been excessively removed during previous surgery, the external nose can lose support.
The specific appearance depends on which structures are affected and how severely they have been compromised.
In revision cases with substantial structural deficiency, rebuilding support may be more important than simply changing the visible shape of the nose.
When Is Rib Cartilage Considered?
Rib cartilage may be considered when the available septal cartilage is insufficient for the amount of reconstruction or support required.
This can occur in patients who have undergone multiple previous operations, patients with significant structural weakness, or cases requiring substantial reconstruction.
However, rib cartilage is not automatically necessary simply because a patient is undergoing revision rhinoplasty.
If sufficient usable cartilage remains and the required correction is limited, another approach may be appropriate.
The choice of cartilage should follow the structural requirements of the operation.
Can CT Show the Nasal Septum?
CT imaging can provide useful information about the internal nasal structures, including septal deviation and the relationship between the septum and surrounding structures.
However, imaging does not replace physical examination.
Cartilage strength, skin characteristics, scar tissue, and some aspects of previous surgical changes need to be evaluated clinically.
For complex or previously operated noses, combining imaging findings with physical examination can provide a more complete understanding of the anatomy.
How Does Dr. Kim Hye-Young Evaluate the Septum?
At Y-Young Plastic Surgery in Seoul, Dr. Kim Hye-Young evaluates the septum as part of the entire nasal structure rather than considering it only as a source of cartilage.
The assessment may include septal deviation, available cartilage, structural strength, previous septal or rhinoplasty surgery, tip support, and the degree of reconstruction required.
The objective is not to harvest as much cartilage as possible.
The objective is to preserve or create adequate nasal support while using the amount and type of graft material appropriate for the planned correction.
Frequently Asked Questions
Is septal cartilage enough for rhinoplasty?
It can be sufficient for some patients, particularly when adequate cartilage is available and the required structural change is limited. More complex reconstruction may require another cartilage source.
Can I have rhinoplasty after septoplasty?
Yes, but previous septal surgery may affect the amount and condition of remaining septal cartilage. The septum should be evaluated before determining the surgical plan.
Does a deviated septum cause a crooked nose?
It can contribute to external nasal deviation, but the nasal bones and other cartilage structures may also be involved.
Does revision rhinoplasty always require rib cartilage?
No. Rib cartilage is considered when stronger or more abundant graft material is required. The decision depends on the remaining nasal structure and the extent of reconstruction.
