What Does A Deviated Septum Look Like?

A deviated septum is a condition where the bone and cartilage that divide your nasal cavity into two nostrils (the septum) is shifted to one side. Instead of sitting perfectly straight down the middle of your nose, it curves, bends, or is angled, which can narrow one or both of your nasal passages. This structural difference is often invisible from the outside, but it can be seen with a simple medical examination and can cause a range of breathing and sinus issues.

What Does A Deviated Septum Look Like From the Outside?

For most people, a deviated septum does not change the external appearance of the nose. You cannot usually tell someone has one just by looking at their face. The external shape of the nose is determined by the nasal bones and upper cartilage, while the septum sits deeper inside.

In rare and severe cases, a deviated septum can cause a visibly crooked nose. This often happens when the deviation is caused by a traumatic injury that shifted the entire nasal structure. However, the absence of a crooked nose does not mean the septum is straight. Many people with significant internal deviations have perfectly straight-looking noses from the outside.

How Doctors Visualize the Internal Structure

To see a deviated septum, a doctor typically uses a nasal speculum. This is a small instrument that gently opens the nostril so the doctor can look inside. They also use a bright headlight to illuminate the nasal passage. This examination is called anterior rhinoscopy and is done in a standard office visit.

During this exam, the doctor is looking at the shape of the septum as it runs from the front of the nose to the back. They will also assess the size of the nasal turbinates. These are small, bony structures on the side walls of the nose that warm and humidify the air you breathe. In many cases, the turbinate on the side opposite the deviation grows larger over time, a process called compensatory hypertrophy, which can further narrow the airway.

In some cases, a doctor may use a thin, flexible scope with a camera called an endoscope to get a more detailed view of the deeper nasal passages. This allows them to see how far back the deviation extends and if it is contributing to problems with the sinuses or the drainage pathways.

Visual Signs During a Physical Exam

When a doctor looks inside, a deviated septum has distinct visual characteristics. The septum will appear to bow or curve to one side rather than running straight down the center. This curve can be smooth and C-shaped, or it can have a sharp bend or an S-shape.

Sometimes, the deviated part of the septum has a ridge or a spur. A spur is a sharp, pointed projection of bone or cartilage that can push against the side wall of the nose. These spurs can sometimes cause nosebleeds or headaches because they press on sensitive tissues.

The visual exam also reveals the consequences of the deviation. One nasal passage will often look noticeably smaller than the other. The mucous membranes on the deviated side may look dry or irritated because of the increased airflow passing over them, while the other side may look swollen and red.

How a Deviated Septum Affects Breathing

The visual narrowing of the airway translates directly into breathing problems. Air must travel through the narrower passage, which creates a feeling of obstruction. This is often described as a constant stuffiness that does not go away with decongestants or allergy medications.

The severity of symptoms does not always match the severity of the deviation. Some people have a significant curve and breathe fine, while others have a mild curve and feel very congested. This depends on the exact location of the deviation, the size of the turbinates, and the natural width of the individual’s nasal passages.

Breathing problems often worsen at night. When you lie down, blood pools in the nasal tissues, causing them to swell slightly. This swelling can turn a mild daytime obstruction into a significant nighttime one, leading to snoring and disrupted sleep.

Common Symptoms Associated With the Condition

Nasal obstruction is the primary symptom, but a deviated septum can cause more than just a stuffy nose. Many people experience frequent sinus infections. The altered airflow and drainage patterns can prevent the sinuses from clearing properly, creating an environment where infections can take hold.

Other symptoms include frequent nosebleeds, especially if there is a spur that dries out the lining of the nose. Facial pain and headaches can also occur, particularly if the deviation is pressing on the nasal side wall. Some people experience postnasal drip, which is mucus that runs down the back of the throat, causing a persistent cough or sore throat.

Many people also report sleeping on one side specifically to keep the more open nasal passage facing upward. This is a common workaround that patients mention to their doctors, and it is a strong indicator that the septum is causing a chronic obstruction.

Diagnosing the Severity of the Deviation

Diagnosis is based on the physical examination. The doctor looks for the visual signs of a curve and assesses how much of the airway is blocked. They will also ask about your symptoms, including how long you have had trouble breathing, whether it is worse on one side, and if it changes with the seasons.

It is important to distinguish a deviated septum from other causes of nasal congestion. Allergies, chronic sinusitis, and nasal polyps can all cause similar symptoms. The physical exam helps differentiate these conditions because a deviated septum is a structural issue, not an inflammatory one.

Some doctors may recommend a CT scan of the sinuses if they suspect additional problems. This imaging test is not needed to diagnose a deviated septum, but it can provide a detailed view of the nasal anatomy and reveal if sinus disease is also present.

Treatment Options and Surgical Considerations

Treatment begins with managing symptoms. Nasal steroid sprays can reduce swelling in the nasal tissues and help keep the airway open, even if they do not straighten the septum itself. Saline rinses can keep the nasal passages moist and clear of irritants. Antihistamines are only helpful if you also have allergies.

When medical management does not provide enough relief, surgery is the definitive treatment. The procedure is called a septoplasty. During this surgery, the surgeon straightens the septum and removes the obstructing parts of bone and cartilage. This surgery is performed through the nostrils, so there are no external cuts or visible scars.

Septoplasty is generally performed on an outpatient basis, meaning you go home the same day. Recovery typically involves some swelling, congestion, and mild discomfort for about a week. The goal of the surgery is not to create a perfectly straight septum but to improve airflow and resolve the symptoms that are bothering you.

When You Should See a Doctor

You should consider seeing a doctor if nasal congestion is a constant problem that interferes with your daily life. If you have had repeated sinus infections that require antibiotics, or if you cannot sleep well because you cannot breathe through your nose, a medical evaluation is appropriate.

Recurrent nosebleeds and facial pain are also reasons to seek an evaluation. A doctor can determine if these issues are related to the structure of your septum or if they point to another underlying condition. A proper diagnosis is the first step toward finding a treatment that actually works for your specific anatomy.
