Treatment usually begins with
Specialist Assessment
Nasal Endoscopy
Medical Management
Surgical Correction

You may need this evaluated if...
A deviated septum evaluation is recommended when these signs appear:
- Difficulty breathing through one or both nostrils
- Frequent nosebleeds
- Recurrent sinus infections
- Noisy breathing during sleep
A deviated septum is a well-understood, correctable condition, and most patients see excellent results from treatment.
What is Deviated Nasal Septum?
A deviated nasal septum occurs when the wall between the nostrils is off-centre, which can make breathing through one side of the nose difficult.
Very Common
A significant proportion of people have some degree of septal deviation.
May Be Present from Birth or Injury
Can result from natural development or a previous nose injury.
Not Always Symptomatic
Many people with a deviated septum have no noticeable symptoms.
Correctable with Surgery
Septoplasty offers a lasting solution for significant breathing difficulty.
Common Symptoms
- Difficulty breathing through one or both nostrils
- Nasal congestion, often worse on one side
- Frequent nosebleeds
- Recurrent sinus infections
- Noisy breathing during sleep
What Increases Your Risk
A combination of medical, lifestyle and environmental factors can increase the likelihood of this condition.
How It Is Diagnosed
A structured assessment confirms the diagnosis and helps guide the right treatment plan.
Physical Examination
A visual and instrument-based examination assesses the septum's position.
Nasal Endoscopy
A thin scope provides a more detailed view of the nasal passage.
CT Scan
Imaging may be used to assess associated sinus involvement in complex cases.
Treatment Approaches
Medical Care
- Nasal decongestants for temporary symptom relief
- Nasal corticosteroid sprays to reduce inflammation
- Allergy management if contributing to congestion
Surgical Care
Septoplasty straightens the deviated septum to improve airflow and is considered when breathing difficulty significantly affects daily life or sleep.
Treatment decisions are based on symptoms, test results, timing and overall health, not a single test.
Know When to Act
Recognising these signs early and acting promptly is important for the best outcome.
