Deviated Nasal Septum: Causes of a Permanently Blocked Nose

Watch the Video on Deviated Nasal Septum (DNS)

Introduction

In this video, Dr. Akbar Abbas explains what a Deviated Nasal Septum (DNS) is, how it differs from nasal allergy, and why proper diagnosis is essential before deciding on treatment.

A persistently blocked nose is one of the most common reasons patients visit an ENT specialist. While many people assume they need surgery, the cause may vary from person to person.

What is a Deviated Nasal Septum?

The nasal septum is the wall of cartilage and bone that separates the two nasal passages. In many people, the septum is slightly off-centre, which is perfectly normal and often causes no symptoms.

However, when the deviation is significant enough to block airflow, it can lead to persistent nasal obstruction and difficulty breathing through the nose.

Common Symptoms of Deviated Nasal Septum

Patients with a symptomatic deviated nasal septum may experience:

• Persistent nasal blockage
• Difficulty breathing through one or both nostrils
• Symptoms lasting for months or years
• Reduced airflow that does not improve completely

DNS or Nasal Allergy?

Many patients have both nasal allergy and a deviated nasal septum at the same time.

Symptoms of nasal allergy may include:

• Sneezing
• Runny nose
• Itchy nose
• Watery eyes

Unlike DNS, allergic symptoms often improve with medications such as nasal sprays and anti-allergy tablets.

Distinguishing between these two conditions is important because their treatments are different.

Does Everyone with Deviated Nasal Septum (DNS) Need Surgery?

No.

Many people have a mildly deviated septum without any breathing problems and never require treatment.

Surgery is usually considered only when:

• Nasal blockage is persistent.
• Symptoms do not improve with appropriate medical treatment.
• The blocked nose significantly affects daily life.

An ENT specialist will determine whether symptoms are due to DNS, allergy, or a combination of both.
