What is a Deviated Nasal Septum (DNS)?
A deviated nasal septum (DNS) occurs when the thin wall of bone and cartilage separating the two nasal passages is displaced or crooked from the midline. A mild deviation may cause no symptoms, while a more pronounced deviation can narrow one or both nasal passages and interfere with normal airflow. A deviated septum may occur alone or together with enlarged turbinates, allergic rhinitis, chronic sinus disease, or other nasal conditions that contribute to breathing difficulties.
What is the Importance of Timely Treatment?
Timely evaluation matters when a deviated nasal septum causes persistent nasal obstruction, recurrent nosebleeds from the deviation, or sleep and breathing difficulties. An ENT specialist can assess whether the septal deviation causes the symptoms or whether other conditions, such as enlarged turbinates, allergic rhinitis, nasal valve dysfunction, or chronic rhinosinusitis, also contribute. A mild or asymptomatic deviation generally does not require treatment.
What are the Common Symptoms of a Deviated Nasal Septum (DNS)?
- Difficulty breathing through one or both nostrils
- Persistent nasal blockage or congestion
- Nasal obstruction that is worse on one side
- Difficulty breathing during exercise
- Frequent nasal congestion
- Recurrent nosebleeds
- Dryness or crusting inside the nose
- Mouth breathing, particularly during sleep
- Snoring
- Disturbed or poor-quality sleep
- Facial pressure or discomfort in some patients
- Recurrent sinus symptoms when associated sinus disease is present
- Reduced sense of smell in some patients
- Headaches or facial discomfort in selected cases
Causes and Risk Factors of a Deviated Nasal Septum (DNS)
Causes
- A deviated nasal septum may be present from birth or develop after injury to the nose. During childhood, the nasal septum may also become displaced as the nose and facial structures grow.
- Trauma, including sports injuries, falls, road-traffic injuries, or previous nasal procedures, can shift the septal cartilage or bone.
- In some individuals, the specific cause cannot be identified.
Risk Factors
- Previous nasal or facial trauma
- Sports-related nasal injuries
- Falls or accidents
- Previous nasal surgery or procedures
- Congenital or developmental differences in nasal structure
- Childhood nasal trauma
- Conditions associated with abnormal nasal or facial development
- Repeated nasal injury
- Age-related changes in nasal structures
Latest Research and Technologies in the Treatment of Deviated Nasal Septum (DNS) in Thailand
- Modern assessment of deviated nasal septum (DNS) focuses on identifying the location and severity of deviation and its contribution to symptoms. Nasal endoscopy provides detailed visualisation, while CT may be used for selected cases involving chronic rhinosinusitis, trauma, complex anatomy, or surgical planning. Septoplasty remains the main surgical treatment for persistent symptoms, with techniques emphasising targeted correction, structural preservation, appropriate patient selection, and postoperative care.
Treatment options for Deviated Nasal Septum (DNS)
Septoplasty : Septoplasty is the main surgical treatment for persistent symptomatic septal deviation. During the procedure, the surgeon accesses the septum through the nose and corrects or removes selected portions of displaced cartilage and bone while preserving adequate structural support.

Septorhinoplasty: Patients with significant external nasal deformity, structural collapse, previous trauma, or complex nasal obstruction may require septorhinoplasty or reconstructive procedures in addition to septal correction. These procedures are individualised according to functional and, when relevant, cosmetic requirements.
- Clinical assessment:
- Medical and Symptom History: Evaluation includes the duration and severity of nasal obstruction, whether symptoms are worse on one side, history of nasal trauma, recurrent nosebleeds, mouth breathing, snoring, sleep disturbance, exercise-related breathing difficulty, allergies, recurrent sinus symptoms, previous nasal surgery, and use of nasal medicines.
- Nasal Examination: The ENT specialist examines the external nose and internal nasal passages for septal deviation, turbinate enlargement, mucosal inflammation, crusting, discharge, nasal valve narrowing, and other anatomical causes of obstruction.
- Assessment of Associated Conditions: Clinicians may assess for allergic rhinitis, chronic rhinosinusitis, nasal polyps, turbinate hypertrophy, nasal valve dysfunction, recurrent epistaxis, or other conditions that can produce symptoms similar to DNS.
- Functional Assessment: In selected patients, objective assessment of nasal airflow or patient-reported symptom scores may document obstruction severity and evaluate treatment outcomes.
- Imaging Tests:
- CT Scan of the Paranasal Sinuses: Consider CT when chronic sinus disease, significant anatomical abnormalities, previous trauma, or complex surgical anatomy needs evaluation. It is not routinely required for every uncomplicated septal deviation.
- Nasal Endoscopy: Provides direct visualisation of the nasal septum and surrounding structures and is useful for diagnosis and preoperative assessment.
- Additional Imaging: Further imaging may be considered when there is a history of significant trauma, unusual symptoms, suspected mass lesions, or other structural abnormalities.
- Symptoms may improve when you treat associated inflammation or congestion. Intranasal corticosteroids may help with allergic or inflammatory nasal swelling, while antihistamines may help patients with allergic rhinitis. Saline nasal irrigation can help moisturise and clear the nasal passages. Decongestants may provide short-term relief in selected situations but should not be used excessively because prolonged use of topical nasal decongestants can cause rebound congestion.

Frequently Asked Questions
Recovery depends on whether the condition is managed medically or surgically. Medications for associated allergies or inflammation may improve symptoms over days to weeks, but they don't correct the structural deviation. After septoplasty, many patients can resume light daily activities within several days, while internal healing and complete recovery may take several weeks.
Yes. A deviated nasal septum generally does not affect the ability to walk or perform normal physical activities. However, significant nasal obstruction may make strenuous exercise more uncomfortable because breathing through the nose can be difficult. After septoplasty, doctors usually encourage early walking, but you may need to temporarily limit strenuous activity.
Many advanced Thai ENT centres provide modern diagnostic and surgical facilities, including nasal endoscopy, CT imaging when indicated, endoscopic septoplasty, turbinate reduction, nasal airflow assessment, and postoperative monitoring.
Many major Thai hospitals have international-patient departments that may assist with medical records, specialist consultations, treatment coordination, visa documentation, travel arrangements, accommodation, interpretation, and postoperative follow-up. Services vary between hospitals.
Consider an ENT or rhinology specialist experienced in evaluating nasal obstruction and performing septoplasty. Important factors include access to nasal endoscopy, appropriate imaging when required, assessment of associated conditions, experience with functional nasal surgery, postoperative care, and the ability to manage complex or recurrent nasal obstruction.
There is no single success rate for DNS treatment because outcomes depend on the severity and location of the deviation, associated nasal conditions, surgical technique, baseline symptoms, and individual healing. Septoplasty can improve nasal airflow and obstruction in appropriately selected patients, but symptoms may persist when allergies, turbinate enlargement, nasal valve dysfunction, chronic sinus disease, or other conditions also contribute to obstruction.
Many tertiary Thai hospitals have ENT and rhinology specialists experienced in diagnosing and treating deviated nasal septum. Depending on the patient's symptoms, treatment may involve ENT specialists, rhinologists, allergy specialists, pulmonologists, or other clinicians when associated conditions such as allergies, asthma, or chronic sinus disease are present.
Risks depend on the treatment approach. Septoplasty may involve bleeding, infection, nasal crusting, temporary numbness, persistent obstruction, septal perforation, adhesions, changes in nasal shape, or the need for additional treatment. Complications are uncommon, but patients should discuss their individual risks with their surgeon before surgery.
Seek prompt medical evaluation after a significant nasal injury, particularly if there is persistent bleeding, marked swelling, severe pain, visible deformity, or difficulty breathing. A septal haematoma, a collection of blood within the septum, requires urgent assessment and treatment to prevent cartilage damage. Do not attempt to straighten the nose yourself. Clear fluid draining from the nose, severe headache, confusion, vision changes, or other signs of significant head injury require emergency assessment.
A deviated septum does not always alter the external appearance of the nose. However, significant trauma or structural damage can affect nasal shape or support. Whether correction is needed depends on the symptoms, anatomical findings, and functional impact. Septoplasty alone may not correct an external deformity; selected patients may require septorhinoplasty.
An asymptomatic deviated septum may not cause long-term problems and may not require treatment. When it causes significant obstruction, symptoms such as mouth breathing, sleep disturbance, or persistent difficulty breathing through the nose may continue. Associated conditions, including allergies or chronic rhinosinusitis, may also require separate treatment.
Congenital or developmental septal deviation cannot always be prevented. You may reduce the risk of trauma-related deviation by using appropriate protective equipment in contact sports, following road-safety measures, and taking precautions against facial injuries. Prompt assessment after significant nasal trauma can help identify fractures or septal haematoma early.
