Does a deviated septum cause snoring? Learn how nasal obstruction impacts sleep, the connection with sleep apnea, and effective treatments like septoplasty, lifestyle changes, and remedies for long-term relief. A deviated septum affects approximately 80% of people to some degree, making it one of the most common nasal structural abnormalities. For many individuals struggling with persistent snoring, understanding whether their deviated septum is the culprit can be crucial for finding effective treatment solutions.
The relationship between a deviated septum and snoring is complex but well-documented. When the thin wall separating your nostrils becomes displaced or crooked, it can significantly impact airflow and breathing patterns during sleep. This structural issue often leads to the vibrations and obstructions that create snoring sounds.
Research from the American Academy of Otolaryngology shows that 35-45% of people with moderate to severe deviated septums experience regular snoring. Understanding this connection helps millions of snorers identify whether surgical or non-surgical interventions might provide lasting relief.

What is a Deviated Septum?
The nasal septum is a thin wall of bone and cartilage that separates your left and right nasal cavities. In an ideal anatomy, this septum runs straight down the middle of your nose, creating equal-sized nostrils and balanced airflow.
A deviated septum occurs when this wall shifts to one side, creating unequal nasal passages. One nostril becomes narrower while the other becomes wider. This imbalance affects breathing patterns and can contribute to various respiratory issues, including snoring.
Types of Septal Deviations
Medical professionals classify septal deviations based on severity and location:
Mild Deviation (Grade 1):
- Septum touches the lateral nasal wall
- Minimal impact on breathing
- Often goes unnoticed without examination
- Affects 60-70% of the general population
Moderate Deviation (Grade 2):
- Septum significantly blocks one nasal passage
- Noticeable breathing difficulties
- Often requires medical intervention
- Present in 15-20% of people
Severe Deviation (Grade 3):
- Complete or near-complete blockage of one nostril
- Significant breathing impairment
- Almost always requires surgical correction
- Affects 5-10% of the population
Common Causes of Deviated Septum
Cause | Percentage of Cases | Description | Prevention |
---|---|---|---|
Congenital | 70-75% | Present from birth due to developmental factors | Not preventable |
Trauma/Injury | 20-25% | Sports injuries, accidents, physical altercations | Protective equipment, safety measures |
Aging Process | 3-5% | Gradual changes over time | Not preventable |
Previous Surgery | 1-2% | Complications from nasal procedures | Choosing experienced surgeons |
How Does a Deviated Septum Cause Snoring?
A deviated septum narrows or blocks one side of the nasal passage, disrupting normal airflow and causing increased resistance when breathing through the nose. This often leads to mouth breathing during sleep, which dries out airway tissues and increases vibration, the root cause of snoring. The obstruction can also cause turbulent airflow and noisy breathing, making snoring more likely and louder.
A deviated septum contributes to snoring through several interconnected mechanisms. Understanding these pathways helps explain why some people with septal deviations snore while others don’t.

Airflow Obstruction Mechanics
When the nasal septum deviates, it creates an imbalanced airflow pattern that directly contributes to snoring:
Increased Air Velocity:
- Narrowed nasal passage forces air to move faster
- Higher velocity creates more turbulent airflow
- Turbulence causes soft tissues to vibrate more intensely
- Results in louder, more persistent snoring sounds
Pressure Differences:
- Blocked nostril creates negative pressure
- Body compensates by breathing through mouth
- Mouth breathing leads to throat tissue vibration
- Combines nasal and oral snoring patterns
Compensation Breathing Patterns
People with deviated septums often develop compensatory breathing habits that worsen snoring:
- Mouth Breathing Preference
- Easier than struggling through blocked nostril
- Causes throat and tongue tissues to dry out
- Increases likelihood of tissue collapse during sleep
- Creates deeper, more resonant snoring sounds
- Single Nostril Dependence
- Over-reliance on the unobstructed nostril
- Increased workload leads to tissue swelling
- Swelling further narrows already compromised airway
- Creates cycle of worsening obstruction
- Sleep Position Adaptations
- Sleeping on side to favor open nostril
- Position changes throughout night disrupt sleep quality
- Partner sleep disruption from movement and snoring
- Reduced REM sleep affects overall health
Inflammatory Response Impact
Deviated septums often trigger chronic inflammation that exacerbates snoring:
Tissue Swelling Patterns:
- Constant airflow turbulence irritates nasal tissues
- Chronic inflammation causes persistent swelling
- Swollen tissues further narrow already compromised airways
- Creates self-perpetuating cycle of obstruction and snoring
Mucus Production Changes:
- Irritated tissues produce excess mucus
- Thicker secretions from chronic inflammation
- Mucus accumulation blocks remaining airway space
- Requires mouth breathing, increasing snoring intensity

FAQs – Frequently Asked Questions
Does a deviated septum really cause snoring?
Yes, a deviated septum can cause snoring by blocking normal airflow through the nose. This obstruction forces mouth breathing, leading to vibration of tissues in the throat, which produces snoring sounds.
Can a deviated septum make sleep apnea worse?
A deviated septum does not directly cause sleep apnea but worsens symptoms by limiting airflow. Poor breathing patterns increase airway resistance, making obstructive sleep apnea more severe and disruptive to sleep.
What are the main symptoms of a deviated septum besides snoring?
Apart from snoring, symptoms include nasal congestion, difficulty breathing through one or both nostrils, frequent sinus infections, headaches, postnasal drip, and sleep disturbances caused by reduced airflow through nasal passages.
How is a deviated septum diagnosed in people with chronic snoring?
Doctors diagnose a deviated septum through physical examination of nasal passages, medical history, and sometimes nasal endoscopy. If chronic snoring persists, ENT specialists evaluate whether surgery or non-surgical treatments are required.
Can surgery completely stop snoring caused by a deviated septum?
Septoplasty surgery improves airflow by correcting the septum. While it often reduces snoring significantly, it may not completely stop it, especially if other factors like obesity or throat anatomy also contribute.
