Is a CT scan really necessary before functional rhinoplasty? 

What is checked in tests for rhinitis nose surgery

VERYGOOD PLASTIC SURGERY

When looking into rhinitis nose surgery or functional rhinoplasty,

you may have one question before your consultation.

“Do I have to get a CT scan for functional rhinoplasty?”

To give the short answer first,

a CT scan is not always necessary in every case.

​

To identify the cause of nasal congestion,

the current symptoms and the inside of the nose need to be examined first,

and only when necessary,

additional tests such as nasal endoscopy or CT can be used.

​

In other words, what matters in functional rhinoplasty

is not how many tests are done, but

determining which tests are needed to identify

the cause of the current nasal congestion.

1. Do I have to get a CT scan before functional rhinoplasty?

Not necessarily.

A CT scan is an imaging test that can show

the structure of the nose and sinuses.

However, not everyone gets a CT scan simply because they have nasal congestion.

First, the symptoms and the inside of the nose are examined directly,

and only when additional structural evaluation is deemed necessary

can a CT scan be considered.

For example,

depending on which direction the septum is bent,

whether a sinus issue is also suspected,

or whether a more detailed look at the internal nasal structure

is needed, the scope of testing may differ.

So rather than thinking,

“Functional rhinoplasty = CT scan no matter what,”

it is important to choose the tests that fit the current condition.

2. What is checked first in a nasal congestion consultation?

What is checked before testing is

the symptoms you are currently feeling.

Even with the same nasal congestion,

the pattern can differ from person to person.

For example,

whether only one nostril is persistently blocked,

whether both sides alternate,

whether it gets worse when lying down,

whether symptoms change by season,

and whether there is also a runny nose or sneezing.

Based on this information,

it can be further examined whether the congestion is related to a structural problem,

or whether inflammation of the mucosa or allergies are a major factor.

📌 The beginning of diagnosis before functional rhinoplasty is

accurately identifying the current symptoms, not the testing equipment.

3. What is the difference between nasal endoscopy and CT?

Nasal endoscopy and CT

show different areas.

Neither test is better than the other;

their roles differ depending on what needs to be checked.

If the condition of the nasal mucosa

or the size of the inferior turbinates needs to be checked directly,

an endoscopic exam can be helpful,

and if the internal nose and sinus structure

need a broader evaluation,

a CT scan may also be considered.

4. How is deviated septum diagnosed?

A deviated septum is a condition in which

the septum that divides the inside of the nose left and right

is bent to one side.

The front part of the septum

and the areas inside the nose that can be directly seen

can be examined through a physical exam or nasal endoscopy.

However, if the position or shape of the bend

needs to be evaluated more broadly,

imaging tests can be used together as needed.

What is important here is

not deciding on surgery simply because the septum is bent.

Together with the septal shape,

you need to comprehensively look at whether there are actual nasal obstruction symptoms,

whether one passage is narrowed,

and whether there are other structural causes.

5. Can inferior turbinate hypertrophy also be confirmed through testing?

​

​

Yes, it can be checked.

The inferior turbinates are located on both sides inside the nose

and are structures involved in regulating the temperature and humidity of incoming air.

If the inferior turbinates are significantly swollen due to rhinitis or repeated irritation,

the space inside the nose can become narrower,

causing a feeling of nasal congestion.

The size of the inferior turbinates and the condition of the mucosa

can be checked through an internal nasal exam,

and whether surgical treatment is needed is determined by looking at the symptoms and treatment response together.

Therefore, even if the inferior turbinates are large,

surgery is not always necessary.

How much they are actually affecting the current nasal congestion is

the more important criterion.

6. Why are photos taken during a rhinoplasty consultation?

Functional rhinoplasty is not just a surgery that looks inside the nose.

If an aesthetic rhinoplasty is planned as well,

photos can be used to objectively assess the current nose shape.

From the front,

you can check whether the nose bends to one side,

and the width of the nose and nostrils,

and from the side,

the bridge height, hump,

and the projection and angle of the tip can be examined.

Tests and photos serve different purposes

After separately checking functional and cosmetic issues,

the process of balancing both within one surgical plan

is needed.

7. How do preoperative test results affect the surgical plan for functional rhinoplasty?

The purpose of testing

is not simply to find many problems.

Its significance lies in distinguishing the parts that actually need surgery

from those that do not.

For example,

if septal deviation is identified as the main cause of nasal congestion,

septoplasty may be considered,

and if inferior turbinate hypertrophy is also contributing,

additional treatment for that area may also be reviewed.

On the other hand,

if allergic rhinitis and mucosal swelling are judged to be the main causes,

rhinitis treatment and management may take priority over structural surgery.

Also, if you have concerns about the appearance of your nose,

the scope of functional correction and

the design of the tip or bridge

should be planned together so they do not affect each other.

In other words,

test results are less about deciding “which additional surgery to do”

and more about identifying “which surgery I need.”

8. Frequently asked questions about functional rhinoplasty tests

Q. If I have nasal congestion, will a CT always show a problem?

No.

Nasal congestion can result not only from structural problems

but also from rhinitis or changes in the mucosa.

Therefore, CT results alone

cannot explain every cause of nasal congestion.

Q. Can the nose be blocked even if the CT is normal?

Yes.

In cases such as mucosal swelling or allergic rhinitis,

it can be difficult to judge the severity of symptoms based on imaging alone.

The current symptoms and exam findings

need to be checked together.

Q. If I am getting rhinoplasty, do I also need functional tests?

If you usually do not have nasal congestion or breathing difficulty,

the evaluation can focus on aesthetic rhinoplasty.

Conversely, if nasal congestion keeps recurring,

it is necessary to check whether there is a functional cause

separate from the outward design.

Q. If a deviated septum is found, do I have to have surgery right away?

No.

Even with a deviated septum,

some people have no symptoms.

After checking whether the actual breathing difficulty

is related to the shape of the septum,

the decision about surgery is made.

Q. Can the rhinoplasty method change depending on the test results?

Yes.

Depending on the state of the septum,

the support structure inside the nose,

and the scope of functional correction,

the surgical plan, such as what cartilage to use or how to support the nasal tip,

may change.

The key to preoperative testing for functional rhinoplasty is not “doing a lot,” but 

“checking what is needed”
