Deviated Septum Self-Test: An Easy-To-Follow Guide
A deviated septum is a condition that affects the structure of the nasal passages, making it difficult for air to flow freely through the nostrils. This can result in breathing difficulties, snoring, and recurring sinus infections. Knowing how to self-test for a deviated septum can help you decide whether you should see an ENT specialist. This guide includes an easy-to-follow self-test for identifying potential signs of a deviated septum.
Symptoms Of A Deviated Septum
Many people may not realise they have a deviated septum until they experience symptoms such as:
- Difficulty breathing through one or both nostrils
- Frequent nasal congestion, even without a cold
- Recurrent sinus infections or headaches
- Facial pain or pressure
- Snoring or sleep disturbances
Why Perform a Self-Test?
Conducting a self-test can provide early indications of whether you may have a deviated septum. This is especially useful if you experience persistent symptoms such as nasal congestion or difficulty breathing. A self-assessment can aid discussions with an ENT specialist, who can provide an accurate diagnosis and recommend suitable treatment options.
Step-by-Step Self-Test Guide
Use a Mirror for External Observation
Begin by examining your nose in the mirror. Check for any crookedness or an uneven nasal bridge. If one nostril appears narrower than the other or if your nose looks misaligned, this may be a sign of a deviated septum. Not all deviations are externally visible, but this can be a useful indicator.
Observe Your Breathing
Close one nostril by pressing your finger against it, then breathe through the open nostril. Repeat the process on the other side. Pay attention to any noticeable differences in airflow. If one nostril feels more blocked or difficult to breathe through, it could indicate a deviated septum.
Check for Nasal Congestion
Take note of how often your nose feels congested or blocked. If this occurs frequently, even when you do not have a cold or allergies, it may indicate a deviated septum. Chronic congestion is a common symptom of this condition.
Test in Different Positions
Lie flat on your back and observe your breathing through both nostrils. Then, turn onto each side and notice if the blocked sensation worsens on one side. If one position causes more difficulty breathing than the other, this could indicate uneven airflow caused by a deviated septum.
Keep A Symptom Log
Record any recurring symptoms, such as nasal congestion, breathing difficulties, or snoring. Identify any patterns or triggers that worsen your symptoms. This diary can provide valuable information to help with diagnosis and treatment planning when speaking with an ENT specialist.
If your self-test indicates a significant obstruction on one side, a surgical correction may be the most effective long-term solution. Deviated Septum Surgery in Singapore, also known as a septoplasty, is a common procedure performed to straighten the internal cartilage and bone to restore balanced airflow.

Limitations of Self-Testing
While these self-assessments can provide an early indication of a deviated septum, they cannot reveal the full extent of the deviation or rule out other nasal conditions that can cause similar symptoms, such as chronic sinusitis or nasal polyps. It is important to distinguish between a crooked bone and swollen soft tissue. For patients whose blockage is caused by environmental allergies rather than a deviated bone, Inferior Turbinate Hypertrophy Treatment in Singapore can help shrink the nasal linings and provide significant relief from congestion. An accurate diagnosis requires a professional evaluation by an ENT specialist who may use diagnostic tools such as nasal endoscopy to thoroughly assess nasal structure and function. This allows for a precise diagnosis and ensures that you receive the most appropriate treatment for your condition.
When To See an ENT Specialist
If your self-test suggests you may have a deviated septum, or if you notice persistent symptoms that interfere with your daily activities, it is advisable to consult an ENT specialist. Signs that warrant professional evaluation include difficulty breathing, frequent sinus infections, or sleep disturbances such as snoring or sleep apnea. A deviated septum often contributes to mouth breathing and restless nights. Consulting a Sleep Specialist in Singapore is advisable if your nasal blockage is accompanied by heavy snoring or daytime fatigue, as these may be signs of obstructive sleep apnoea. Addressing these symptoms early can lead to more effective treatment and prevent further complications.
Conclusion
A self-test for a deviated septum can help you become more aware of your nasal function, but it is only the first step. If symptoms persist or worsen, seeking professional help is necessary for an accurate diagnosis and effective treatment, ensuring optimal outcomes and long-term relief.
If you suspect you may have a deviated septum based on your self-assessment, reach out to Ascent ENT for professional evaluation and tailored treatment options.
