A thin wall of bone and cartilage called the nasal septum separates the two sides of your nose. When this structure is centered, air can flow through both nasal passages with little resistance. However, a perfectly straight septum is uncommon. Research suggests that approximately 80% of people have some degree of septal deviation. This condition may develop after a nasal injury or be present from birth.
Although a deviated septum is common, not everyone needs treatment. The severity of the deviation and whether it interferes with your daily life are the main factors that determine if medical intervention is necessary.
Recognizing the Signs of a Deviated Septum

Some people have a slightly crooked septum without experiencing noticeable symptoms. Others may have a more significant deviation that makes breathing through the nose difficult. In certain cases, the difference may also be visible from the outside, such as when the nose appears uneven, or one nostril looks smaller than the other.
A more pronounced deviation can interfere with normal drainage and airflow, potentially contributing to several health concerns, including:
- Frequent sinus infections
- Persistent nasal stuffiness or difficulty breathing through the nose
- Disrupted sleep or sleep-related breathing problems
- Recurring ear infections
Colds, flu, allergies and nasal polyps may also contribute to congestion and inflammation, making symptoms more difficult to manage.
If you regularly experience sinus problems, an ENT evaluation can help determine whether a deviated septum is contributing to your symptoms.
When Is Treatment Necessary?
Diagnosing a deviated septum typically involves a physical examination of the nose. Depending on your symptoms and the findings of the initial evaluation, your specialist may recommend nasal endoscopy or imaging to get a closer look at the nasal passages and surrounding structures.
Treatment depends on how much the deviation affects your breathing and overall comfort. If your symptoms are mild or nonexistent, you may not need any treatment. When inflammation makes symptoms worse, medications can help reduce swelling and improve airflow. However, medication cannot straighten the septum itself.
For patients with significant breathing difficulties that do not improve with medication, a surgical procedure called septoplasty may be an appropriate option.
During septoplasty, the surgeon adjusts the bone and cartilage that separate the nasal passages to improve airflow. The procedure is generally performed on an outpatient basis, so most patients return home the same day.
Find Relief From Persistent Nasal Symptoms
A deviated septum does not automatically mean you need surgery. However, ongoing congestion, recurring sinus infections or difficulty breathing comfortably should not be ignored.
