A deviated nasal septum is a common anatomical abnormality that may go unnoticed for years or, conversely, cause persistent breathing difficulties, recurrent sinusitis, or sleep disturbances. Many people come to the doctor’s office wondering whether the asymmetry of their nasal septum is normal or whether it requires specialized evaluation. This article discusses the most common causes, the symptoms to watch for, and the criteria that guide the decision to request a medical evaluation at Mallorca Medical Group.

What is a deviated nasal septum?

The nasal septum is the structure of cartilage and bone that divides the nasal cavity into two halves. In clinical practice, it is common to find some degree of septal asymmetry in the general population without this implying a health problem. A deviated nasal septum is considered clinically significant when it significantly impairs airflow, contributes to nasal obstruction, or is associated with persistent symptoms. Distinguishing between an anatomical variant with no functional impact and a deviation requiring treatment is one of the primary objectives of the medical evaluation.

Most Common Causes of a Deviated Nasal Septum

A deviated septum can be congenital or acquired. Among the most common causes are:

• Abnormalities during fetal development or passage through the birth canal.
• Nasal injuries, including sports-related blows, falls, or traffic accidents.
• Asymmetric growth of the nasal skeleton during childhood and adolescence.
• Previous nasal surgeries that have altered the septal support.

In many cases, the deviation goes unnoticed for years until an additional factor—such as a respiratory infection or a change in the nasal mucosa—makes the obstruction of airflow more apparent. Certain factors, such as participating in contact sports or a history of nasal trauma that was not evaluated at the time, can cause the septal asymmetry to become more pronounced over time; therefore, the progression of symptoms is a relevant clinical finding.

Symptoms and signs that may indicate a deviated septum

Not all deviations of the nasal septum cause symptoms, but when the deviation is significant, signs such as the following may appear:

• Nasal congestion on one or both sides, often more pronounced when lying down.
• Difficulty breathing through the nose during physical exercise.
• Snoring or a feeling of not having had restful sleep.
• Sinusitis or recurrent nasal infections.
• Dryness or occasional nosebleeds on the side most affected.
• A persistent sensation of pressure or facial congestion.

The persistent presence of several of these symptoms is often the reason why a patient seeks a personalized medical evaluation.

How Is a Deviated Nasal Septum Diagnosed?

The diagnosis combines the patient’s medical history with a detailed physical examination. It typically includes:

• Medical history focused on the progression of respiratory symptoms.
• Anterior rhinoscopy to assess the visible septal anatomy.
• Nasal endoscopy when a more comprehensive view of the nasal cavity is needed.
• Imaging studies, such as computed tomography, in selected cases.

An assessment from a plastic surgery perspective also provides a comprehensive view of both respiratory function and the aesthetic harmony of the nose, which is particularly useful when a deviated septum coexists with an abnormality in the nasal contour. In some cases, this assessment can be supplemented with functional tests, such as rhinomanometry, which allow for the objective measurement of airflow resistance in each nostril and provide additional information to guide treatment decisions.

Impact on Quality of Life: Breathing, Sleep, and Sinusitis

A significant deviated septum does not only affect daytime breathing. Persistent nasal obstruction has been linked to poorer sleep quality, snoring, and, in some cases, an increased risk of sleep-related breathing disorders. It can also contribute to recurrent sinusitis by impeding the natural drainage of the paranasal sinuses. The extent of the impact varies depending on the severity of the deviation and each patient’s individual sensitivity, making an individualized functional assessment necessary before considering any treatment.

Dr. García Ceballos, FCCP, states: “The decision to perform surgery on a deviated nasal septum should be based on an individualized functional assessment, not solely on imaging findings. The goal is to improve the patient’s breathing and quality of life using an approach that is safe and appropriate for each case.”

When to Evaluate a Treatment and Therapeutic Options

Not every deviated nasal septum requires surgery. In mild cases, treatment may focus on conservative measures, such as nasal corticosteroids or managing allergic conditions that exacerbate the obstruction. When the deviation is functionally significant and symptoms persist despite medical treatment, septoplasty may be considered—a procedure designed to correct the position of the septal cartilage and bone to improve airflow.

If there is also a cosmetic issue with the bridge or tip of the nose, septorhinoplasty may be considered, which combines a functional and cosmetic approach in a single procedure. The decision to proceed should always be based on a personalized medical evaluation that takes into account each patient’s anatomy, symptoms, and expectations, with a focus on surgical safety and natural, long-lasting results.

Factors That Influence the Valuation

Clinical Presentation	Usual management
Mild deviation, with no significant symptoms	Follow-up and conservative measures
Moderate obstruction with persistent symptoms	Specialized functional assessment
Significant obstruction affecting sleep or recurrent sinusitis	Evaluation of individualized surgical treatment
Deviation associated with nasal cosmetic abnormality	Combined functional and aesthetic assessment

Conclusion

A deviated nasal septum is an anatomical condition that may have little clinical significance or, conversely, may significantly affect breathing and quality of life. Recognizing the symptoms and understanding the most common causes allows you to make an informed decision about whether it is time to seek a specialized medical evaluation. At Mallorca Medical Group, we evaluate nasal anatomy from both a functional and aesthetic perspective, prioritizing safety and a personalized approach for each case.

Each patient has a unique anatomy and medical history, so there is no single recommendation that applies to all cases. A combination of a detailed examination, additional tests when necessary, and a clear discussion of expectations is what allows us to develop, if appropriate, a proportionate and safe treatment plan.

Frequently Asked Questions

Does every case of a deviated nasal septum require surgery?

No. Many deviations are minor and do not cause significant symptoms, so they do not require surgical treatment. The need for septoplasty is assessed only when there is a significant functional impact, following an individualized medical evaluation.

Can a deviated septum cause headaches or facial pain?

In some patients, persistent nasal obstruction and sinus congestion may be associated with a sensation of pressure or facial discomfort. However, headaches can have many possible causes, so it is important to rule out other causes through a comprehensive medical evaluation.

What is the difference between septoplasty and septorhinoplasty?

Septoplasty corrects only the position of the nasal septum for functional purposes. Septorhinoplasty combines this functional approach with cosmetic correction of the nasal bridge or tip when both issues are present in the same patient.

How long does recovery take after surgical treatment of the nasal septum?

Recovery varies depending on each individual case and the technique used. As a general guideline, functional improvement is usually evident within the first few weeks, while complete resolution of internal inflammation may take several months, always under appropriate medical supervision.
