If one side of your nose always feels blocked or you struggle to breathe through your nose despite allergy medication, the problem may not be inflammation at all. A deviated septum changes the structure of the nasal passages, limiting airflow in ways medication can’t correct.
A deviated septum occurs when the thin wall of cartilage and bone that separates the nasal passages is displaced to one side. While many people have some degree of septal deviation, a more significant deviation can narrow one or both nasal passages enough to restrict airflow. The result is often ongoing nasal obstruction, nasal congestion, a blocked nose, and difficulty breathing through the nose.
Although medications such as nasal steroid sprays or allergy treatments may reduce swelling inside the nose, they cannot straighten a crooked septum. When the underlying problem is structural, symptoms often continue despite medical therapy.
For patients whose breathing difficulties are caused by a deviated septum, septoplasty is designed to restore airflow by correcting the structural blockage. Dr. Mani H. Zadeh is a board-certified otolaryngologist and rhinologist who performs septoplasty using minimally invasive techniques through the nostrils without external incisions. He also performs sinus surgery when additional treatment is needed for chronic sinus disease or other structural conditions.

How a Deviated Septum Restricts Normal Airflow
The nasal septum divides the nose into two separate air passages. Ideally, each side provides adequate space for air to move smoothly into the lungs. When septal deviation narrows one side of the nose, airflow becomes uneven.
Even a moderate deviated septum can create noticeable breathing problems because airflow naturally follows the path of least resistance. As one passage becomes restricted, the other side must compensate, yet many patients still experience a sensation of a constantly blocked nose.
Common causes of a deviated septum include:
- Natural development as the face grows
- Previous nasal trauma from sports injuries, falls, or accidents
Reduced airflow often forces patients to breathe through their mouths, especially during physical activity or while sleeping. Mouth breathing may contribute to dry mouth, sore throat upon waking, and poorer sleep quality. Many patients seek treatment because they want to know how to improve breathing with a deviated septum after years of struggling with daily congestion.
Symptoms That Suggest Airflow Is Being Blocked by a Deviated Septum
Symptoms caused by nasal obstruction vary depending on the severity of the deviation and whether other conditions are present.
Many patients experience:
- Constant nasal congestion, often worse on one side
- Difficulty breathing during exercise
- Trouble breathing comfortably while sleeping
- Chronic mouth breathing
- Snoring and interrupted sleep
- Recurrent sinus infections caused by impaired sinus drainage
- Frequent nosebleeds due to dry, irritated nasal tissues exposed to turbulent airflow
Some patients notice that one side of the nose feels completely blocked while the other side alternates between open and congested. Others experience symptoms year-round rather than only during allergy season.
Because these symptoms overlap with allergies and chronic sinusitis, an examination by an experienced rhinologist is important to determine whether the primary problem is inflammation, anatomy, or both. Dr. Zadeh uses diagnostic tools such as nasal endoscopy and CT imaging when appropriate to identify structural causes of breathing problems.
Why Nasal Sprays and Allergy Medications Cannot Correct a Crooked Septum
Many patients begin treatment with saline rinses, allergy medications, antihistamines, or nasal steroid sprays. These treatments may reduce swelling of the nasal lining and improve symptoms when inflammation is contributing to congestion.
However, medications cannot reposition cartilage or bone.
Because the structural narrowing remains, many people experience only temporary or partial relief from medication. When symptoms persist despite appropriate medical therapy, septoplasty may be recommended to correct the underlying obstruction rather than simply manage congestion.
Patients frequently ask, does septoplasty improve nasal airflow? For individuals whose breathing problems are primarily caused by a deviated septum, the answer is often yes because the procedure creates a more balanced nasal passage by correcting the structural narrowing. This is also how septoplasty fixes a deviated septum, allowing air to move more freely through the nose.

How Septoplasty Restores Better Nasal Airflow
Septoplasty improves airflow by correcting the structural obstruction inside the nose. The procedure is performed entirely through the nostrils, so there are no visible external incisions. During the procedure, the lining covering the septum is carefully elevated, allowing access to the underlying cartilage and bone. The portions causing obstruction are reshaped or repositioned, preserving healthy supporting structures, before the lining is returned to its normal position.
As the nasal passages become more balanced, airflow improves naturally. This is how septoplasty helps nasal breathing, making it easier for air to pass through both sides of the nose.
Improved airflow also supports healthier sinus ventilation and drainage. Better ventilation can reduce mucus buildup and may lower the likelihood of recurrent sinus infections related to poor drainage.
Once healing is complete, breathing often becomes easier during exercise, sleep, and everyday activities for people whose symptoms were caused by a deviated septum.
Dr. Zadeh tailors every septoplasty procedure to the patient’s anatomy, symptoms, and treatment goals rather than using a one-size-fits-all approach.
Procedures That May Be Combined With Septoplasty for Maximum Airflow
A deviated septum is not always the only cause of nasal obstruction.
Some patients also have enlarged turbinates, which are structures inside the nose that warm and humidify incoming air. When swollen or enlarged, the turbinates can further narrow the airway.
In these cases, turbinate reduction may be performed during septum surgery to create additional breathing space. Combining both procedures allows multiple structural causes of obstruction to be addressed during a single operation.
Patients with chronic sinus disease may also benefit from combining septoplasty with endoscopic sinus surgery. Straightening the septum can improve surgical access to the sinus openings while sinus surgery removes blockages that interfere with normal drainage. Dr. Zadeh recommends combined treatment only when both conditions are contributing to symptoms.
Every surgical plan is based on the patient’s anatomy, imaging findings, symptoms, and examination rather than using the same procedure for every individual.
What Patients Can Expect After Septoplasty
Septoplasty is typically performed as an outpatient procedure under general anesthesia, allowing patients to return home the same day.
Some swelling and temporary congestion are expected during the early healing period. As swelling gradually decreases over the following weeks, patients usually notice progressive improvement in airflow.
For many individuals undergoing deviated septum surgery for a blocked nose, the long-term benefits may include:
- Easier nasal breathing
- Better sleep quality
- Reduced snoring
- Fewer sinus infections related to poor drainage
- Improved daily comfort and quality of life
For people who have struggled with ongoing nasal obstruction despite medical treatment, these improvements can make breathing through the nose feel noticeably easier once healing is complete.

Conclusion
Chronic nasal obstruction, nasal congestion, and a blocked nose caused by a deviated septum are structural problems that often require a structural solution. While medications may temporarily reduce swelling, they cannot correct septal deviation or restore normal airflow when the septum itself is blocking the nasal passage.
If breathing problems continue despite medical treatment, an evaluation by a rhinologist can determine whether septoplasty alone or combined with sinus surgery is the most appropriate approach.
If you are experiencing ongoing nasal obstruction or difficulty breathing through your nose, schedule a consultation with Dr. Mani H. Zadeh at Los Angeles Sinus Institute. After a comprehensive evaluation, Dr. Zadeh can determine whether septoplasty or a combination of minimally invasive nasal procedures can restore healthier nasal airflow and improve your breathing.
