At a glance
A deviated nasal septum occurs when the wall separating the two nasal passages is displaced or curved to one side. It may be present from birth or develop after an injury to the nose. Some people have no symptoms, while others may experience persistent nasal blockage, difficulty breathing through the nose, snoring, recurrent sinus problems or nosebleeds. Treatment depends on the severity of the deviation and the symptoms it causes. Mild cases may be managed without surgery, while significant obstruction may require a procedure to improve airflow.
Introduction
A Deviated Nasal septum can make breathing through one or both nostrils more difficult when the septum significantly narrows the nasal passage. The condition may develop naturally as the nose grows or result from an injury, such as a sports injury, fall or accident. While a slight deviation is common and may not require treatment, a more pronounced displacement can affect breathing, sleep and overall nasal comfort.
What Is a Deviated Nasal Septum, and What Causes It?
The nasal septum is the structure made of bone and cartilage that separates the left and right nasal passages. Ideally, it sits relatively centrally, allowing air to pass through both sides of the nose. When the septum bends or shifts away from the centre, one nasal passage may become narrower than the other.
A deviated septum does not always cause noticeable problems. Some people may have a deviation without experiencing any symptoms. However, significant narrowing can interfere with normal airflow and may become more noticeable during colds, allergies or other conditions that cause swelling inside the nose.
Common Causes
A deviated septum can occur for several reasons. Some people are born with a septal deviation, while others develop one as the nose grows during childhood or adolescence. Injury is another common cause and may occur because of a fall, sports-related impact, accident or other trauma to the nose.
In some cases, an injury may have occurred years earlier, and the person may not immediately realise that it contributed to their breathing difficulties. Changes within the nasal structures over time can also make symptoms more noticeable.
Common Symptoms
Symptoms vary depending on the degree and location of the deviation. Common symptoms may include:
- Difficulty breathing through one or both nostrils
- Persistent nasal blockage
- A feeling that one side of the nose is more blocked than the other
- Frequent nasal congestion
- Snoring or noisy breathing during sleep
- Recurrent sinus-related symptoms
- Frequent nosebleeds in some people
- Facial pressure or discomfort in certain cases
Nasal blockage may become more noticeable while sleeping or during an episode of a cold or allergy.
How Is a Deviated Septum Diagnosed?
Diagnosis generally begins with a discussion about your symptoms, their duration and whether you have experienced previous nasal injuries or recurring nasal problems. A doctor may ask whether the blockage is present on one side or both sides and whether it affects sleep, exercise or daily activities.
The nose may then be examined to assess the nasal passages and septum. Depending on the symptoms, an ENT specialist may use a nasal endoscope to obtain a clearer view of structures deeper inside the nose.
Diagnosis is important because nasal obstruction does not always result from a deviated septum. Allergic rhinitis, enlarged turbinates, nasal polyps, chronic sinus problems and other conditions can also restrict airflow. Identifying the actual cause helps determine the most appropriate treatment.
When Is DNS Surgery Recommended?
Treatment depends on the severity of symptoms and their effect on daily life. If the deviation is mild and does not cause significant problems, surgery may not be necessary. Medicines or management of associated conditions such as allergies may help reduce symptoms in selected cases.
When structural blockage remains significant despite appropriate non-surgical management, DNS surgery may be considered. The procedure, commonly known as septoplasty, aims to straighten or reposition parts of the nasal septum to improve airflow through the nose.
The decision to undergo surgery should be based on symptoms, examination findings and the overall condition of the nose. Not every person with a deviated septum requires an operation.
How Is a Deviated Nasal Septum Treated?
Treatment is based on the underlying cause of nasal obstruction and the severity of symptoms. If the septal deviation is not causing significant breathing difficulties, observation may be sufficient.
Non-Surgical Management
Medicines do not straighten a physically deviated septum, but they may help manage conditions that worsen nasal blockage. For example, treatment for allergies or nasal inflammation may reduce swelling inside the nose and improve airflow.
Depending on the individual’s symptoms, a doctor may recommend appropriate nasal medicines or other measures. These should be used according to professional advice, particularly when symptoms are persistent.
Surgical Treatment
When the septum is significantly displaced and causes persistent obstruction, septoplasty may be recommended. During the procedure, the surgeon corrects the problematic portions of the septum while aiming to preserve the important supporting structures of the nose.
The specific surgical approach depends on the location and severity of the deviation and whether other nasal conditions are present. In some patients, additional nasal procedures may be considered when problems such as enlarged turbinates or other structural abnormalities contribute to breathing difficulties.
Recovery After Surgery
Recovery varies between individuals. Temporary congestion, swelling or mild discomfort may occur following surgery. Patients are generally advised to follow post-operative instructions carefully and attend follow-up appointments so that healing can be monitored.
It is important to avoid unnecessary pressure or trauma to the nose during the recovery period. The treating surgeon can provide specific guidance based on the procedure performed.
When Should You See an ENT for Nasal Blockage?
Persistent nasal obstruction should be evaluated when it interferes with breathing, sleep, exercise or daily activities. You may also benefit from an ENT assessment if one side of your nose remains consistently blocked, you experience recurrent nosebleeds, or nasal symptoms continue despite appropriate treatment.
Nasal blockage following an injury should also be assessed, particularly if there is pain, visible deformity, difficulty breathing or swelling. In such situations, identifying structural damage early can help guide appropriate management.
A sudden injury may cause more than a septal deviation. It can also result in damage to the nasal bones or surrounding tissues. Nasal bone fracture treatment depends on the type and severity of the injury, whether the bones have shifted and whether breathing has been affected. Prompt medical assessment is particularly important after significant nasal trauma.
An ENT evaluation can help distinguish a deviated septum from other causes of nasal obstruction and determine whether medication, observation, or a surgical approach is appropriate.
Frequently Asked Questions (FAQs)
What is a deviated nasal septum?
A deviated nasal septum occurs when the wall separating the two nasal passages is displaced or curved away from the center. It may be present from birth or develop following nasal trauma.
Can a deviated septum cause breathing problems?
Yes. A significant deviation can narrow one nasal passage and make breathing through the nose more difficult. Symptoms may become more noticeable during colds, allergies, or sleep.
Does every deviated septum require surgery?
No. Many people have a deviated septum without significant symptoms and do not require surgery. Treatment depends on how much the deviation affects breathing and daily life.
Can medicines correct a deviated septum?
Medicines cannot physically straighten the septum. However, they may help reduce nasal swelling caused by allergies or inflammation and can sometimes improve breathing symptoms.
How long does recovery from septoplasty take?
Recovery varies depending on the individual and the procedure performed. Nasal congestion and swelling may occur during the early healing period, and following post-operative instructions is important for proper recovery.
A deviated septum is common and does not always require treatment. However, significant deviation can contribute to persistent nasal blockage, breathing difficulties, snoring, and other nasal symptoms. Proper examination is important because allergies, enlarged turbinates, sinus conditions, and nasal injuries can produce similar problems.
If nasal obstruction continues, affects your sleep, or follows an injury, consulting an ENT specialist near me can help identify the underlying cause and determine the most suitable treatment approach. Timely evaluation can help ensure that structural and inflammatory causes of nasal blockage are properly assessed and managed.
