Deviated Septum On CT Scan

A deviated nasal septum is a common condition that affects many individuals. When it comes to diagnosing and understanding this condition, CT scans play a crucial role. In this article, we will delve into the world of deviated nasal septums on CT scans, explaining what it is, how it’s diagnosed, and the potential treatment options available.

What Is a Deviated Nasal Septum?

A deviated nasal septum occurs when the thin wall (the nasal septum) that separates your left and right nasal passages is displaced or deviated. This deviation can lead to various health issues, including breathing difficulties and chronic sinus problems.

CT Scans: A Diagnostic Tool CT scans, short for computed tomography scans, are valuable diagnostic tools for assessing a deviated nasal septum. These scans provide detailed cross-sectional images of the nasal passages, allowing healthcare professionals to accurately evaluate the extent and nature of the deviation.

Diagnosing Deviated Nasal Septum on CT Scans:

  1. Image Acquisition: During a CT scan of the nasal area, a series of X-ray images are taken from different angles. These images are then processed by a computer to create detailed cross-sectional images.
  2. Identification of Deviation: In CT scans, a deviated nasal septum appears as an irregularity or displacement of the septal wall. Radiologists can precisely measure the degree of deviation and identify any associated issues such as sinusitis or nasal polyps.

Common Symptoms:

People with a deviated nasal septum may experience various symptoms, including:

  • Nasal congestion
  • Frequent sinus infections
  • Difficulty breathing through one or both nostrils
  • Recurring nosebleeds
  • Snoring or sleep apnea

Treatment Options:

The severity of the deviation and the impact on an individual’s quality of life often determine the course of treatment. Common options include:

  1. Nasal Decongestants: Over-the-counter nasal decongestants can provide temporary relief from congestion but do not address the underlying deviation.
  2. Medications: Depending on associated symptoms, physicians may prescribe medications like antihistamines or corticosteroids to manage symptoms such as congestion and inflammation.
  3. Septoplasty: Septoplasty is a surgical procedure that aims to straighten the deviated nasal septum. It can improve breathing and reduce symptoms associated with the deviation.
  4. Rhinoplasty: In some cases, individuals may opt for rhinoplasty, a cosmetic surgery that can address both functional and aesthetic concerns related to the nasal septum.
  5. Endoscopic Sinus Surgery: When a deviated septum is associated with chronic sinusitis or nasal polyps, endoscopic sinus surgery may be recommended to remove obstructions and improve sinus drainage.


CT scans are invaluable tools for diagnosing and understanding deviated nasal septums. They provide detailed insights into the extent of the deviation and help healthcare professionals determine the most appropriate treatment plan for each individual. If you suspect you have a deviated nasal septum, consult with a medical professional who can assess your condition and recommend the most suitable course of action to alleviate your symptoms and improve your quality of life.
