Deviated Nasal Septum
A deviated nasal septum is a common condition that can significantly impact one's quality of life. The nasal septum is the bone and cartilage that divides the nasal cavity into two nostrils. When it is deviated or off-centre, it can cause a range of issues, from difficulty breathing to chronic sinus infections.
In this comprehensive guide, we will delve into the causes, symptoms, diagnosis, and treatment options for a deviated nasal septum. We will also explore preventative measures and the different types of septal deviations.
What Is a Deviated Nasal Septum?
The nasal septum is ideally situated in the middle of the nose, separating the nasal cavity into two equal parts. However, in many individuals, the septum is deviated to one side, causing one nasal passage to be smaller than the other. This condition is known as a deviated nasal septum.
Types of Deviated Nasal Septum
There are several types of septal deviations, including:
- C-Shaped Deviation: The septum curves to one side, forming a C-shape.
- S-Shaped Deviation: The septum curves in both directions, forming an S-shape.
- Spur: A sharp projection of bone or cartilage that can obstruct airflow.

Congenital Causes
Some people are born with a deviated septum. This can occur during fetal development or as a result of trauma during childbirth.
Trauma
A deviated septum can also be caused by injury to the nose. This could be due to a car accident, sports injury, or physical altercation.
Ageing
The ageing process can affect nasal structures, potentially leading to a deviated septum over time.
Developmental Factors
Growth spurts during adolescence can sometimes cause the septum to deviate as the nose grows and changes shape.
Symptoms of a Deviated Nasal Septum
Obstructed Nasal Breathing
One of the most common symptoms is difficulty breathing through one or both nostrils. This is often more noticeable on one side and can lead to mouth breathing, especially during sleep.
Frequent Nosebleeds
A deviated septum can cause the nasal passages to become dry, leading to frequent nosebleeds.
Recurrent Sinus Infections
The misalignment can obstruct sinus drainage, leading to chronic sinus infections.
Facial Pain
Some individuals experience facial pain or headaches, particularly around the nasal area.
Snoring and Sleep Apnea
The obstruction caused by a deviated septum can lead to snoring and, in severe cases, sleep apnea.
Diagnosis of a Deviated Nasal Septum
Physical Examination
A doctor can often diagnose a deviated septum during a physical examination of the nose, using a nasal speculum to inspect the nasal passages.
Nasal Endoscopy
In some cases, a nasal endoscopy may be performed. This involves inserting a thin, flexible tube with a camera into the nostril to get a detailed view of the nasal passages.
Imaging Tests
Imaging tests such as a CT scan or MRI may be used to get a comprehensive view of the nasal structure and assess the extent of the deviation.
Treatments for a Deviated Nasal Septum
Non-Surgical Treatments
While a severely deviated septum often requires surgical intervention, some non-surgical treatments can alleviate symptoms:
- Decongestants: These medications reduce nasal tissue swelling, helping to keep the airways open.
- Antihistamines: These can help with symptoms related to allergies, which may exacerbate nasal congestion.
- Nasal Steroid Sprays: These can reduce inflammation in the nasal passages, improving airflow.
Surgical Treatments
Septoplasty
Septoplasty is the most common surgical treatment for a deviated septum. This procedure involves straightening the septum by trimming, repositioning, and replacing cartilage or bone.
Rhinoplasty
In some cases, septoplasty is combined with rhinoplasty, a cosmetic procedure to reshape the nose. This is often done to improve the overall appearance and function of the nose.
Turbinate Reduction
Sometimes, a deviated septum is accompanied by enlarged turbinates, structures inside the nose that clean and humidify the air we breathe. Turbinate reduction surgery can improve airflow.
Prevention of a Deviated Nasal Septum
While congenital deviations cannot be prevented, there are measures to reduce the risk of developing a deviated septum due to trauma:
- Wear Seatbelts: Always wear a seatbelt in a vehicle to reduce the risk of facial injury in an accident.
- Use Protective Gear: Wear appropriate protective gear when participating in contact sports or activities that pose a risk of facial injury.
- Avoid Physical Altercations: Engage in conflict resolution strategies to avoid physical confrontations.
Living with a Deviated Nasal Septum
Managing Symptoms
For those who opt not to undergo surgery, managing symptoms is crucial. This can include using nasal sprays and humidifiers and sleeping with the head elevated to improve nasal airflow.
Regular Check-Ups
Regular visits to an ENT (Ear, Nose, and Throat) specialist can help monitor the condition and manage any complications that arise.
Healthy Lifestyle
Maintaining a healthy lifestyle, including staying hydrated and avoiding allergens, can help manage symptoms and improve overall nasal health.

Book an AppointmentWhen to See a Doctor
It is essential to consult a healthcare provider if you experience:
- Persistent difficulty breathing through the nose
- Frequent nosebleeds
- Chronic sinus infections
- Severe facial pain
- Symptoms of sleep apnea, such as loud snoring and episodes of stopped breathing during sleep
Conclusion
A deviated nasal septum is a common condition that can cause significant discomfort and health issues. Understanding the causes, symptoms, and treatment options is crucial for managing this condition effectively. Whether through surgical intervention or symptom management, there are various ways to improve the quality of life for those affected by a deviated septum. Regular consultations with healthcare providers and adopting preventive measures can help mitigate the impact of this condition and lead to better overall nasal health.
Frequently Asked Questions
1. What causes a deviated nasal septum?
A deviated nasal septum is caused by a misalignment of the nasal septum, often due to trauma, birth defects, or natural growth.
2. What are the symptoms of a deviated nasal septum?
Symptoms include difficulty breathing through one side of the nose, frequent nosebleeds, and chronic sinus infections.
3. How is a deviated nasal septum treated?
Treatment includes nasal decongestants, antihistamines, or, in severe cases, surgery (septoplasty) to straighten the septum.
4. What are the types of deviated nasal septum?
Types include C-shaped, S-shaped, and complex deviations, each affecting nasal airflow differently.
5. How is a deviated nasal septum diagnosed?
Diagnosis involves a physical examination and sometimes imaging studies like X-rays or CT scans to assess the severity of the deviation.
