Septoplasty: Straightening a Deviated Nasal Septum

If one side of your nose always feels more blocked than the other, a deviated septum could be the reason. Septoplasty is the surgery that straightens the wall dividing your nostrils, restoring easier, more even breathing through the nose.

What Is a Deviated Septum, and What Is Septoplasty?

The nasal septum is the wall of cartilage and bone that divides the inside of your nose into a left and right passage. Ideally, it runs straight down the middle — but in many people it's bent or off-center, a condition called a deviated septum. When the deviation is severe enough to block airflow, an ENT surgeon can perform septoplasty, a procedure that repositions and trims the septum so both nasal passages open up evenly.

What Causes a Deviated Septum?

• Birth and development — many people are simply born with an asymmetric septum, or it becomes crooked as the face grows
• Nasal trauma — a broken nose, a sports injury, or even a hard bump during childhood can shift the septum out of place
• Long-standing chronic congestion, which can sometimes worsen the impact of an existing deviation over time

Signs and Symptoms

• Difficulty breathing through one or both nostrils, often worse on one side
• Frequent nasal congestion, especially at night
• Recurrent sinus infections due to poor drainage
• Nosebleeds from a dry, irritated septum surface
• Noisy breathing or snoring during sleep
• Facial pain or headaches related to sinus pressure

How the Surgery Works

1. Anesthesia. Septoplasty is usually done under general anesthesia, though local anesthesia with sedation is sometimes used for adults.
2. Incision. The surgeon makes an incision inside the nostril — there are no visible external cuts or bruising in a standard septoplasty.
3. Correcting the deviation. The lining covering the septum is lifted, and the crooked cartilage and bone underneath are straightened, trimmed, or repositioned as needed. Enough structural support is always preserved to keep the nose's shape intact.
4. Closing up. The lining is placed back over the repositioned septum, and dissolvable stitches or soft internal splints may be used to hold everything in place while it heals.
5. Combined procedures. Septoplasty is frequently done alongside turbinate reduction or FESS when those issues are contributing to the blockage as well.

Most septoplasties take 45–90 minutes.

Recovery

• First few days: Mild congestion, some swelling, and light discomfort are expected; nasal splints, if used, are typically removed within a week.
• 1–2 weeks: Most people return to work or school within a week, avoiding strenuous exercise and nose-blowing during this window.
• Several weeks to months: Full resolution of swelling and the final breathing improvement can take a few months to become fully apparent.

Risks and Considerations

• Bleeding or a septal hematoma (a collection of blood inside the septum, which needs prompt drainage)
• Infection
• A small hole in the septum (septal perforation) in rare cases
• Temporary numbness of the front teeth or upper lip
• Persistent obstruction if other structures (turbinates, sinuses) are also contributing and untreated

The Takeaway

A deviated septum is extremely common, but it doesn't have to mean living with permanent nasal blockage. Septoplasty has a strong track record for improving nasal airflow, reducing sinus infections, and improving sleep quality. If breathing through your nose has never felt quite right, an ENT evaluation can determine whether your septum is the cause — and whether surgery would help.
