Deviated Nasal Septum: Causes, Symptoms, Diagnosis, and Treatment

Introduction

A deviated nasal septum happens when the thin wall between your nostrils is off-center. This wall, called the septum, divides your nose into two sides. When it is not straight, it can block airflow. Many people have some septum deviation, but for some, it causes problems. In this blog, we will explain the causes, symptoms, diagnosis, and treatment for deviated nasal septum. You will also learn when to see an ENT specialist for nasal blockage.

Causes of Deviated Nasal Septum

There are several reasons why someone may have a deviated nasal septum. Sometimes, people are born with it. Other times, it develops later in life. For example, an injury to the nose can cause the septum to shift. In some cases, the septum bends as you grow. Rarely, certain medical conditions can also affect the septum’s shape.

Birth defect (present at birth)

Injury to the nose (such as from sports or accidents)

Normal growth during childhood or teenage years

Rare medical conditions affecting cartilage or bone

Symptoms of Nasal Septum Deviation

Not everyone with a deviated septum has symptoms. However, some people notice problems. For instance, you may have trouble breathing through one or both nostrils. Sometimes, the symptoms are mild. Other times, they can affect daily life. Common nasal septum deviation symptoms include:

Blocked or stuffy nose, often on one side

Frequent nosebleeds

Snoring or noisy breathing during sleep

Facial pain or pressure

Frequent sinus infections

Difficulty sleeping

Additionally, some people may notice a dry mouth from breathing through the mouth at night.

Diagnosis of Deviated Nasal Septum

To diagnose a deviated nasal septum, a doctor will ask about your symptoms. Next, they will examine your nose. Usually, an ENT specialist uses a special light and a small tool to look inside your nose. Sometimes, a thin camera called an endoscope helps them see better. In rare cases, imaging tests like a CT scan may be needed. However, most diagnoses are made with a simple exam.

Treatment Options for Deviated Septum

Treatment for deviated septum depends on how severe your symptoms are. For mild cases, home care or medicine may help. However, if symptoms are severe, surgery may be needed. Here are the main options:

Medical Treatments

Decongestant sprays or pills to reduce swelling

Antihistamines for allergies

Saline nasal sprays to keep the nose moist

Nasal steroid sprays to reduce inflammation

These treatments can ease symptoms, but they do not fix the septum’s shape.

Surgical Treatment (Septoplasty)

If medical treatment does not help, surgery may be needed. Septoplasty is the most common surgery for this problem. During septoplasty, the doctor straightens the septum. This can improve airflow and reduce symptoms. Most people recover quickly and feel better soon after surgery. According to the American Academy of Otolaryngology, septoplasty is safe and effective for most patients.

Lifestyle Tips and Home Care

Even with a deviated septum, you can take steps at home to feel better. For example, you can:

Use a humidifier to keep air moist

Drink plenty of water

Rinse your nose with saline solution

Avoid irritants like smoke or strong smells

Sleep with your head raised to ease breathing

In addition, try to avoid picking your nose, as this can cause nosebleeds.

Prevention

It is not always possible to prevent a deviated nasal septum. Many people are born with it. However, you can lower your risk of injury by:

Wearing seat belts in cars

Using protective gear during sports

Being careful to avoid falls or accidents

While these steps help prevent injury, they cannot stop all cases of septum deviation.

When to See an ENT Specialist

Sometimes, home care is not enough. You should see an ENT specialist for nasal blockage if:

You have trouble breathing through your nose

You get frequent nosebleeds

You have repeated sinus infections

Your sleep is often disturbed

Symptoms do not improve with home care

Early treatment can help you feel better and avoid problems.
