Deviated Nasal Septum: Symptoms, Diagnosis and Treatment Options

A blocked nose can make everyday activities such as sleeping, exercising and breathing comfortably more difficult. While nasal congestion is often associated with allergies or infections, a structural problem inside the nose may also be responsible. One such condition is a deviated nasal septum.

A deviated septum occurs when the thin wall separating the two nasal passages is displaced to one side. This can narrow one or both passages and interfere with normal airflow. Some people have a deviated septum without experiencing any symptoms, while others develop persistent nasal obstruction, difficulty breathing or sleep-related problems.

Understanding deviated nasal septum symptoms, how the condition is diagnosed and which treatment options are available can help patients decide when to seek medical advice.

This article explores the causes, symptoms, diagnosis and treatment of a deviated septum, including medication, septoplasty, potential surgical benefits, complications and recovery.

What Is a Deviated Nasal Septum?

The nasal septum is the internal wall made of cartilage and bone that separates the left and right sides of the nasal cavity. Ideally, it sits relatively centrally, allowing air to pass through both nasal passages.

When this wall bends or shifts towards one side, it is described as a deviated nasal septum.

The degree of deviation varies. A mild deviation may have little effect on breathing, whereas a more pronounced deviation can narrow the nasal airway and cause persistent obstruction.

A deviated septum is common, and its presence does not automatically mean that treatment or surgery is necessary. Treatment is generally considered when the deviation causes troublesome symptoms or contributes to other clinical concerns. 

What Causes a Deviated Septum?

There are several possible causes of a deviated septum. Some people are born with the condition, while others develop it following an injury.

Congenital differences

The septum may develop off-centre before birth. In some cases, the position of the septum may also be affected during childbirth.

Injury to the nose

An impact to the nose can displace the cartilage or bone. Such injuries may occur during contact sports, falls, road accidents or other incidents involving the face.

Changes during growth

The nose and its supporting structures change as a person grows. A deviation may become more noticeable during development or later in life.

Age-related structural changes

Changes in the nasal structures over time may affect the position or shape of the septum in some people.

It is important to distinguish a structural deviation from temporary nasal swelling. Allergies, infections and inflammation can narrow the nasal passages even when the septum itself has not changed. These conditions may coexist with a deviated septum and contribute to symptoms.

Deviated Nasal Septum Symptoms

Not everyone with a deviated septum experiences symptoms. When symptoms occur, they often relate to restricted airflow or irritation inside the nose.

Common symptoms include:

1. Nasal obstruction

One of the most recognisable symptoms is a blocked nose. The obstruction may be more noticeable on one side, depending on the position and severity of the deviation.

2. Difficulty breathing through the nose

A narrowed nasal passage can make it harder to breathe comfortably through the nose, particularly during physical activity or when congestion develops.

3. Persistent nasal congestion

Some people experience ongoing congestion. Allergies or respiratory infections may make the obstruction more noticeable by causing additional swelling.

4. Frequent nosebleeds

A deviated septum may contribute to dryness or irritation of the nasal lining in some people, which can increase the likelihood of nosebleeds.

5. Noisy breathing or snoring

Restricted nasal airflow may contribute to noisy breathing during sleep or snoring. However, snoring can have several other causes and does not confirm a deviated septum.

6. Disturbed sleep

People who struggle to breathe through their nose may experience discomfort during sleep or find themselves changing position to breathe more easily.

7. Facial discomfort or headaches

Some people report facial discomfort or headaches alongside nasal symptoms. These symptoms are not specific to a deviated septum, so other possible causes may need to be investigated.

The presence and severity of symptoms vary from person to person. Seek medical assessment if you have persistent nasal blockage, frequent nosebleeds, or breathing difficulties that affect sleep.

How Is a Deviated Septum Diagnosed?

A deviated septum diagnosis usually begins with a discussion of symptoms and an examination of the nose. An ENT specialist can assess whether the septum is displaced and whether it is likely to be contributing to the patient’s symptoms.

Medical history

The clinician may ask about:

• How long the nasal obstruction has been present.
• Whether one or both nostrils are affected.
• Previous nasal injuries or surgery.
• Allergies, recurrent infections or other nasal conditions.
• Snoring, sleep disruption or breathing difficulties.
• Previous treatments and whether they provided relief.

This information helps distinguish structural obstruction from other possible causes of nasal symptoms.

Physical examination

The clinician examines the external nose and looks inside the nasal passages using a suitable instrument and light. This helps assess the position of the septum and identify visible narrowing or other abnormalities.

Nasal endoscopy

In some cases, a nasal endoscopy may be recommended. This examination uses a thin scope with a light and camera to provide a closer view of structures deeper inside the nasal cavity.

Imaging

A CT scan is not required for every deviated septum diagnosis. A clinician may recommend imaging when there is a specific reason to investigate deeper nasal structures, associated sinus disease or other concerns.

The appropriate investigations depend on the patient’s symptoms and examination findings. 

Deviated Septum Treatment Options

The appropriate deviated septum treatment depends on the severity of the deviation, the symptoms it causes and whether other conditions are contributing to nasal obstruction.

A deviated septum does not always require treatment. If it causes no symptoms, monitoring without intervention may be appropriate. When symptoms are present, treatment may involve medication, surgery or management of other nasal conditions.

1. Medication for symptom management

Medication may help when nasal swelling, allergies or inflammation contribute to breathing difficulties.

Depending on the clinical assessment, a healthcare professional may recommend:

• Nasal corticosteroid sprays: These can reduce inflammation and swelling inside the nose.
• Antihistamines: These may help when allergic symptoms contribute to congestion, sneezing or a runny nose.
• Decongestants: These may provide temporary relief from congestion in selected circumstances, but they are not suitable for everyone. Some nasal decongestant sprays can cause rebound congestion when used for too long.

Medication can improve symptoms associated with inflammation, but it does not physically straighten a deviated septum.

2. Managing contributing conditions

A patient may have a deviated septum alongside allergic rhinitis, enlarged nasal turbinates or another condition affecting airflow.

Treating these additional problems may improve breathing even if the septum remains deviated. An ENT specialist can assess whether more than one factor is contributing to the obstruction.

3. Septoplasty

When a deviated septum causes persistent, troublesome symptoms, a clinician may consider surgery called septoplasty.

Septoplasty is a procedure that straightens the nasal septum to improve airflow through the nasal passages. It may be considered when symptoms remain significant despite appropriate non-surgical management.

The decision should be based on the examination, the patient’s symptoms, their treatment history and a discussion of expected benefits and risks.

What Is Septoplasty and How Does It Work?

Septoplasty is a surgical procedure used for deviated septum correction. It focuses on the internal structures of the nose rather than primarily changing its external appearance.

During the procedure, the surgeon works through the nose to access the septum. Depending on the type and location of the deviation, cartilage or bone may be reshaped, repositioned or selectively removed before the septum is placed in a more central position.

The procedure is generally performed under anaesthesia. Its duration and specific techniques depend on the complexity of the deviation and the surgeon’s assessment.

In some cases, septoplasty may be combined with another nasal procedure if there are additional structural or functional concerns.

Septoplasty vs rhinoplasty

These procedures have different primary purposes:

Feature	Septoplasty	Rhinoplasty
Main purpose	Corrects the internal nasal septum to improve airflow when appropriate.	Changes the external shape or structure of the nose.
Primary focus	Functional correction.	Cosmetic, reconstructive or functional goals, depending on the procedure.
Does it correct a deviated septum?	Yes, it is the operation specifically used to straighten the septum.	Not necessarily. Rhinoplasty alone does not automatically correct an internal septal deviation.
Can they be combined?	Yes, when clinically appropriate.	May be combined with septoplasty when both internal and external correction are required.

The best approach depends on whether the patient’s concern involves breathing, nasal appearance or both.

When Is Deviated Septum Surgery Considered?

Deviated septum surgery may be considered when the structural problem causes symptoms that significantly affect everyday life.

An ENT specialist may discuss septoplasty when:

• Persistent nasal obstruction interferes with comfortable breathing.
• Nasal symptoms affect sleep or daily activities.
• Appropriate medical treatment has not provided sufficient relief from contributing inflammation or congestion.
• The examination indicates that the septal deviation is an important cause of the obstruction.
• The expected benefits of surgery justify its risks for the individual patient.

Surgery is not automatically recommended simply because the septum appears crooked. A clinician needs to assess whether correcting it is likely to address the patient’s symptoms.

It is also important to understand that septoplasty may not resolve symptoms caused by allergies, chronic inflammation or other conditions that remain untreated.

Deviated Septum Surgery Benefits

For appropriately selected patients, septoplasty may provide several benefits.

Improved nasal airflow

Straightening the septum can widen a narrowed nasal passage and improve the movement of air through the nose.

Easier nasal breathing

Patients whose breathing difficulties are mainly caused by septal deviation may experience easier nasal breathing after recovery.

Potential improvement in sleep-related symptoms

If nasal obstruction contributes to disturbed sleep or snoring, improving airflow may help with some symptoms. However, septoplasty is not a guaranteed cure for snoring or obstructive sleep apnoea, which may have additional causes.

Reduced obstruction-related discomfort

Some patients may experience improvement in symptoms associated with nasal blockage. The extent of improvement depends on the underlying causes and the individual response to treatment.

Improved quality of life

When nasal obstruction significantly affects everyday activities, successful treatment may make breathing and daily routines more comfortable.

Expected results vary. Before surgery, patients should discuss which symptoms are likely to improve, which may persist and whether additional treatment may be needed.

Deviated Septum Surgery Complications and Risks

Septoplasty is commonly performed, but it is still a surgical procedure and carries potential risks. Understanding these risks helps patients make informed decisions.

Possible deviated septum surgery complications include:

Potential complication	Explanation
Bleeding	Some bleeding may occur after surgery. Significant bleeding may require medical attention.
Infection	Infection can develop after surgery, although it is not inevitable.
Persistent nasal obstruction	Breathing difficulties may continue if the deviation is not fully corrected or other causes of obstruction remain.
Septal perforation	A hole may develop in the septum. Depending on its size and location, it may cause crusting, bleeding or whistling sounds.
Changes in the shape of the nose	Changes to the supporting structures can occasionally affect the external appearance of the nose.
Reduced sense of smell	Some patients may experience changes in their sense of smell.
Septal haematoma	Blood can collect within the septum and may require prompt treatment.
Anaesthesia-related risks	As with other operations requiring anaesthesia, individual risks need to be assessed before surgery.

The likelihood and significance of these complications vary. Patients should discuss their medical history, medications, individual risk factors and expected outcomes with their surgeon before proceeding.

Seek medical advice promptly if you experience heavy bleeding, increasing pain, fever or other concerning symptoms after surgery.

Deviated Septum Surgery Recovery: What to Expect

Recovery after septoplasty varies depending on the surgical technique, the extent of correction and the patient’s overall health.

The first few days

Some swelling, nasal congestion, mild bleeding or discomfort may occur after surgery. The nose may initially feel blocked, even though the septum has been corrected.

The surgeon may use internal splints or other support materials, depending on the procedure.

The first one to two weeks

Many patients can return to some normal activities within approximately one to two weeks, depending on their recovery and the advice of their healthcare team.

During this period, patients may be advised to:

• Follow the surgeon’s instructions for nasal care.
• Avoid blowing the nose until advised that it is safe.
• Avoid strenuous exercise and heavy lifting for the recommended period.
• Attend scheduled follow-up appointments.
• Use only the medicines and nasal products recommended by their clinician.

The following weeks and months

Internal swelling gradually settles, and breathing may continue to improve as healing progresses.

Although initial recovery may take a week or two, the internal tissues can take considerably longer to stabilise fully. Some healing and structural changes may continue for several months.

The surgeon’s instructions should take priority over general recovery timelines because individual procedures and healing experiences differ.

Can a Deviated Septum Be Treated Without Surgery?

Yes, symptoms associated with a deviated septum can sometimes be managed without surgery.

Medication may reduce inflammation or swelling caused by allergies and other nasal conditions. This can improve airflow even though the septum itself remains displaced.

However, non-surgical treatment does not physically correct the structural deviation. If the septum is the main cause of persistent obstruction, septoplasty may be discussed as a treatment option.

The choice between medical management and surgery depends on the patient’s symptoms, examination findings, response to previous treatment and personal preferences.

A healthcare professional can explain the potential benefits and limitations of each approach so the patient can make an informed decision.

When Should You Consult a Deviated Septum Specialist?

Consider consulting an ENT specialist if you experience:

• Persistent blockage in one or both nostrils.
• Difficulty breathing comfortably through your nose.
• Recurrent nosebleeds.
• Nasal obstruction that interferes with sleep or daily activities.
• Symptoms that continue despite appropriate treatment for allergies or congestion.
• Ongoing nasal symptoms following an injury.

An ENT specialist can examine the nasal passages, assess whether a deviated septum is present and determine whether it is contributing to your symptoms.

If you have sustained a recent nasal injury and develop severe pain, significant swelling, heavy bleeding or difficulty breathing, seek prompt medical assessment rather than attempting to reposition the nose yourself.

For patients in Vadodara, an ENT consultation can help establish the cause of persistent nasal obstruction and identify suitable next steps.

Conclusion

A deviated nasal septum is a common structural condition that occurs when the wall separating the nasal passages is displaced to one side. While many people experience no symptoms, others may develop nasal obstruction, difficulty breathing, nosebleeds or sleep-related concerns.

The appropriate deviated septum treatment depends on the severity of symptoms and whether the deviation is the main cause of the problem. Medication may help manage associated inflammation, while septoplasty can correct the structural deviation when surgery is clinically appropriate.

Before considering deviated septum surgery, patients should understand its potential benefits, limitations, recovery requirements and complications. An individual assessment by an ENT specialist can help determine whether medical management, surgery or another approach is suitable.

If persistent nasal blockage or breathing difficulties are affecting your daily life, consider consulting an ENT specialist at Bharti ENT Care in Vadodara. A professional assessment can help identify the underlying cause of your symptoms and guide you towards an appropriate treatment plan.
