Understanding a Deviated Septum

A deviated septum refers to the displacement of the thin wall (nasal septum) that divides the nasal passages. Ideally, this septum is centered, allowing for equal airflow through both nostrils. However, in many people, it veers to one side—either from birth or as a result of trauma—causing one nasal passage to be smaller than the other.

Estimates suggest that up to 80% of individuals have some degree of septal deviation, though not all experience symptoms. For those who do, the condition can significantly hinder nasal breathing, particularly during exercise or sleep, and contribute to complications like chronic nasal congestion, post-nasal drip, and even sleep apnea.

Symptoms may include:

• Difficulty breathing through one or both nostrils

• Frequent nosebleeds

• One-sided nasal blockage

• Facial pressure or sinus headaches

• Disturbed sleep and snoring

At Sangdo Woori Internal Medicine, Dr. Yoo Du-yeol emphasizes early diagnosis and comprehensive management of nasal obstructions like a deviated septum, given their far-reaching impact on respiratory health and sleep quality.

Breathing Challenges Associated with a Deviated Septum

The primary function of the nasal passages is to filter, humidify, and regulate the temperature of air before it reaches the lungs. A deviated septum disrupts this process by reducing airflow, often on one side of the nose. This restriction forces the body to adapt in ways that are less efficient and potentially harmful over time.

Common consequences include:

• Chronic Mouth Breathing: When nasal airflow is limited, patients unconsciously resort to breathing through the mouth. This can lead to dry mouth, halitosis, sore throat, and an increased risk of dental decay and respiratory infections.

• Exercise Intolerance: Physical activities require increased oxygen intake. When nasal resistance is high due to a deviated septum, patients may find even moderate exercise more exhausting.

• Sinus Dysfunction: Reduced airflow hampers sinus drainage, predisposing individuals to recurrent sinus infections and facial discomfort.

Dr. Yoo Du-yeol explains that proper nasal airflow isn't just about comfort—it’s essential for optimal respiratory function, immune defense, and quality of life.

Sleep Disruptions Linked to a Deviated Septum

One of the most overlooked effects of a deviated septum is its disruption of normal sleep patterns. Nasal obstruction can significantly compromise nighttime breathing, making sleep less restorative and more fragmented.

Potential impacts include:

• Snoring: When airflow is partially blocked, it creates turbulence that vibrates the soft tissues of the throat. This vibration results in snoring, which can affect sleep partners as much as the patient.

• Obstructive Sleep Apnea (OSA): A deviated septum can worsen OSA, a condition characterized by repeated pauses in breathing during sleep. Left untreated, OSA increases the risk of hypertension, stroke, heart disease, and cognitive issues.

• Poor Sleep Quality: Constantly waking up to switch positions, breathe through the mouth, or clear the throat can prevent the deep stages of sleep needed for healing and memory consolidation.

Patients who struggle with excessive daytime fatigue, chronic snoring, or frequent awakenings are encouraged to consult Dr. Yoo Du-yeol for a full evaluation of nasal and sleep-related health.

Chronic Post-Nasal Drip and Sore Throat

A common but frustrating outcome of a deviated septum is chronic post-nasal drip (PND)—the accumulation of mucus at the back of the throat due to impaired nasal drainage.

PND occurs when:

• The nasal passages are congested, often forcing mucus down the throat rather than out the nose.

• Environmental allergens, infections, or anatomical blockages increase mucus production.

• The body attempts to clear blocked sinuses by overproducing secretions.

Symptoms of chronic PND include:

• Constant throat clearing

• A feeling of mucus “dripping” or being stuck in the throat

• Chronic cough, especially at night

• Hoarseness or sore throat

• Bad breath due to bacterial buildup

Dr. Yoo Du-yeol warns that persistent post-nasal drip can lead to chronic pharyngitis, tonsil inflammation, and even ear problems due to Eustachian tube dysfunction. Treating the root cause—often the deviated septum—is essential for long-term relief.

Treatment Options

1. Medical Management

For mild to moderate symptoms, Dr. Yoo Du-yeol may initially recommend conservative treatments, such as:

• Nasal corticosteroids to reduce inflammation

• Antihistamines for allergy-related symptoms

• Nasal decongestants for short-term relief

• Saline nasal sprays or rinses to flush irritants and mucus

While these therapies can alleviate discomfort, they do not correct the structural deviation itself.

2. Surgical Intervention: Septoplasty

When symptoms persist despite medical management, septoplasty is often the most effective option. This outpatient surgical procedure involves straightening the deviated septum to restore proper airflow.

Key benefits of septoplasty:

• Improved nasal breathing

• Better sleep and reduced snoring

• Fewer sinus infections and less post-nasal drip

• Enhanced quality of life

Dr. Yoo Du-yeol performs septoplasty with meticulous attention to anatomical detail, tailoring the procedure to each patient’s unique nasal structure and symptoms.

3. Managing Chronic Post-Nasal Drip

In conjunction with correcting the septal deviation, Dr. Yoo may recommend:

• Nasal irrigation using neti pots or saline squeeze bottles

• Topical or oral antihistamines for allergic contributors

• Intranasal steroids to reduce tissue inflammation

• Environmental modifications to reduce dust, smoke, and allergens

Lifestyle Modifications for Improved Breathing and Sleep

Incorporating certain behavioral and environmental changes can significantly enhance symptom control:

Sleep Position

Patients are advised to avoid sleeping on their backs. Side-sleeping helps reduce gravitational pooling of mucus and alleviates snoring by keeping airways more open.

Humidified Air

Dry indoor air can irritate nasal tissues and thicken mucus. A humidifier in the bedroom can promote better sleep by easing congestion and reducing throat irritation.

Allergen Avoidance

For patients with allergic rhinitis, minimizing exposure to triggers like pollen, dust mites, and pet dander can drastically improve symptoms. Dr. Yoo may also recommend skin testing or immunotherapy for persistent allergies.

Hydration

Drinking at least 8 glasses of water daily helps thin mucus secretions, making them easier to clear. Avoiding alcohol and caffeine can also help, as these substances tend to dehydrate the body.

Importance of Follow-Up Care

After initiating treatment—whether medical or surgical—ongoing follow-up is essential. These appointments allow Dr. Yoo Du-yeol to:

• Monitor healing and symptom improvement

• Adjust medications or nasal care routines

• Identify and treat any complications early

Patients who undergo surgery typically return for follow-up within 1–2 weeks and continue periodic visits to assess long-term outcomes and maintain optimal nasal function.
