Deviated Nasal Septum: What It Is and How It’s Treated?

By Dr. Katerina Panagiotidi, MD, PhDc – ENT Surgeon

The nasal septum is the thin vertical wall that separates the right and left nasal airways (nostrils). It’s made of flexible cartilage and fine bone, playing a vital role in supporting the external structure of the nose and allowing normal nasal breathing.

How do I know if I have a deviated septum?

It’s actually very common for the nasal septum to be slightly off-centre. However, a significantly deviated septum can narrow the internal nasal space—usually more on one side—causing nasal congestion and difficulty breathing.

A deviated septum may also lead to frequent headaches, recurring sinus infections, nosebleeds, or even snoring. In more severe cases, it can be the result of nasal trauma, often from minor injuries during childhood or even during birth. Sometimes, no clear cause can be identified.

If you’re experiencing difficulty breathing through your nose or any of the symptoms mentioned above, it’s important to consult an ENT specialist. There are many potential causes for nasal congestion, and a precise diagnosis is essential before attributing the issue to the nasal septum. In some cases, medication may be recommended before considering surgery.

How is a deviated septum corrected?

The only permanent treatment for a deviated nasal septum is surgery. 

There are two main surgical approaches to correction, and choosing the right method is essential for optimal results while minimising risks:

• Internal (Closed) Septoplasty

This is the most common technique and is usually referred to simply as “septoplasty.” It involves a small incision made inside one nostril. Using specialised instruments, the surgeon removes the deviated parts of the septum and straightens the cartilage before suturing it—all done internally, with no external incisions or visible scars.

• Endoscopic Septoplasty

For deviations located deeper in the nasal passage, an endoscopic approach using a thin fibre-optic camera and fine instruments may be more effective. This technique is often combined with other procedures, such as endoscopic sinus surgery, for patients with chronic sinus issues.

If you suspect you may have a deviated nasal septum or are experiencing nasal symptoms that affect your quality of life, don’t hesitate to schedule a consultation.
