Nasal Valve Stenosis: Symptoms and Surgery

Nasal valve stenosis occurs as a result of anatomical narrowing in the narrowest part of the nasal airways. This condition may lead to shortness of breath, nasal congestion, and a reduced quality of life.

Functionally, the nasal valve is a critical structure that regulates airflow through the nose. Narrowing increases the sensation of nasal obstruction and makes breathing more difficult, especially during exercise.

Causes of nasal valve stenosis include previous trauma, nasal surgeries, or structural abnormalities. Early diagnosis is important for preventing permanent respiratory problems.

Treatment options include surgical correction and graft applications. These procedures widen the nasal airway, improve breathing function, and increase the patient’s quality of life.

What Is the Nasal Valve?

The nasal valve is the narrowest air passage within the nose and plays an important role in regulating the air inhaled through the nose. It consists of two parts: the internal and external nasal valves. Narrowing or collapse in this structure may make nasal breathing difficult. Nasal valve insufficiency is one of the important causes of nasal congestion and can be treated with surgical or supportive methods.

What Is Nasal Valve Stenosis?

Nasal valve stenosis is the narrowing of the airway inside the nose. This health condition causes problems especially when taking deep breaths. When airflow is obstructed, individuals experience difficulty breathing. The affected area may extend from the nostrils to the bridge of the nose. In cases of nasal valve narrowing, the nose cannot fully perform its function as an air filter. This problem usually presents as narrowing or collapse in the middle of the nose. A physical collapse is often not visibly apparent but is felt through breathing difficulties. This narrowing of the airways becomes more pronounced, especially during sleep. Therefore, patients frequently experience insomnia.

How Is Nasal Valve Stenosis Diagnosed?

The diagnosis of nasal valve stenosis is made through a series of specific procedures. The patient’s complaints and symptoms are carefully examined. First, a detailed medical history is taken by an ear, nose, and throat (ENT) specialist. During this process, the symptoms experienced by the patient are questioned in detail.

• Physical Examination: A detailed examination of the nasal structure is performed. The doctor investigates areas where the nasal valve may have collapsed and other potential problems.
• Nasal Endoscopy: The internal structure of the nose is visually examined using an endoscope. This procedure is used to determine the location and extent of valve collapse.
• Cottle Maneuver: With this test, the doctor pulls the cheek to widen the nasal valve. If this procedure makes breathing easier, it indicates that valve stenosis is making breathing difficult.

What Are the Symptoms of Nasal Valve Stenosis?

Nasal valve stenosis is a condition that causes serious difficulties in breathing and daily life. This disorder is characterized by distinct symptoms that make breathing difficult:

• Difficulty Breathing: Individuals experience difficulty with airflow through the nostrils, especially while lying down or exercising.
• Nasal Congestion: A persistent feeling of congestion occurs, which frequently leads to mouth breathing.
• Snoring and Sleep Problems: Persistent snoring throughout the night and frequent awakenings reduce the individual’s sleep quality.
• Visible Nasal Changes: External changes such as thinning or asymmetry in the nasal structure may be observed.
• Difficulty Breathing During Exertion: An inability to take in sufficient air through the nose during physical activities is noticeable.
• Other Symptoms: Crusting around the nose and, in severe cases, nosebleeds may occur.

What Are the Causes of Nasal Valve Stenosis?

Nasal valve stenosis may lead to significant problems in the nasal structure. The causes of this condition are generally multifactorial:

• Nasal cosmetic surgeries such as rhinoplasty may cause critical changes in the nasal structure. Weakening of the cartilage during surgery may lead to valve collapse.
• Physical trauma, sports injuries, or accidents may damage the nasal cartilage and thereby weaken the valve.
• Septal deviation is characterized by curvature of the nasal septum. This condition disrupts the nasal structure and increases the risk of valve stenosis.
• The aging process reduces the elasticity and durability of the cartilage in the nasal structure. This causes the valves to weaken and increases the likelihood of collapse.
• Some individuals may genetically have features such as narrow nostrils or a wide columella. These anatomical characteristics may cause nasal valve collapse.
• Chronic inflammation or severe infections may impair the structural integrity of the nasal valve.

Who Is Affected by Nasal Valve Stenosis?

Nasal valve stenosis is a health problem that generally affects certain groups. It is likely to occur after nasal surgeries performed for aesthetic or functional reasons, such as rhinoplasty. Previous trauma to the nasal structure may also predispose individuals to nasal valve stenosis. On the other hand, some individuals experience this problem due to congenital characteristics:

• Those with a deviated septum,
• Those with naturally narrow nostrils,
• Those with an excessively prominent nasal structure.

In addition, the aging process may weaken the nasal cartilage, which may lead to valve collapse.

How Does Nasal Valve Stenosis Affect Quality of Life?

Nasal valve stenosis reduces individuals’ quality of life due to restrictions in the airways. This health problem has particularly negative effects on sleep patterns. Patients who have difficulty breathing frequently wake up at night. This leads to inadequate rest and a feeling of fatigue during the day. When insomnia becomes chronic, physical and mental performance decreases significantly. Respiratory functions are especially critical for athletes.

Typical symptoms seen in individuals with nasal valve stenosis include:

• Persistent nasal congestion
• Increased need to breathe through the mouth
• Snoring at night
• Daytime fatigue

Increased mouth breathing causes problems such as dry throat and pain. In addition, the risk of obstructive sleep apnea is associated with this condition. Reduced sleep quality places stress on cardiovascular health and may increase the risk of hypertension. Chronic fatigue also has negative effects on the immune system. This condition predisposes individuals to metabolic imbalances and the development of various health problems. The combined effects challenge the general health of individuals suffering from nasal valve stenosis and increase psychological stress and social discomfort.

What Are the Diagnostic Methods for Nasal Valve Stenosis?

Nasal valve stenosis is recognized as a health problem that makes breathing difficult. Various methods are used to diagnose this condition. Ear, Nose, and Throat specialists use a series of tests and examination methods when evaluating patients. First, a detailed patient history is taken and a physical examination is performed. During this process;

• The nasal valve area is directly examined with anterior rhinoscopy.
• An external nasal examination is performed.

Physical tests play an important role in evaluating the function of the nasal valve. These tests include:

• Cottle Maneuver: The nasal valve is widened by pulling the cheek laterally, and it is observed whether breathing improves.
• Modified Cottle Maneuver: Similarly, instruments are used to widen the nasal valve, after which breathing capacity is evaluated.
• Bachman Maneuver: Instruments are used to widen the nasal valve, and changes in airflow are examined.

Special tests are also included in the diagnostic process:

Anterior Rhinomanometry: While the patient is sitting upright, airflow is measured through one nostril while the other is closed.

Acoustic Rhinometry: The area and volume of the nasal cavity are measured using sound waves.

Endoscopy: This method is used to identify other possible causes of nasal congestion.

In addition;

• Computed Tomography (CT) Scans: They are used to identify structural problems but are not effective in evaluating dynamic collapse.
• Nasal Obstruction Symptom Evaluation (NOSE) Scale: The severity of nasal congestion is evaluated based on symptoms reported by the patient.

How Is Nasal Valve Stenosis Surgery Performed?

Nasal valve stenosis surgery is a complex procedure performed to improve respiratory functions. The surgery is designed to widen the nasal valve area and stabilize the structures in this region. Different surgical techniques target the internal and external nasal valves.

Internal Nasal Valve Surgery Techniques:

• Spreader grafts: They are placed between the septum and the upper lateral cartilages.
• Butterfly grafts: A butterfly-shaped graft obtained from conchal cartilage is applied to the internal nasal valve area.
• Alar batten grafts: They are placed along the sidewalls of the nose to support the internal nasal valve.

External Nasal Valve Surgery Techniques:

• Lateral cartilage support grafts: They strengthen the lateral crus of the lower lateral cartilages.
• Lateral cartilage J-flap: A J-shaped incision is made in the lateral cartilage.
• Z-plasty: The tissues of the nasal valve area are lengthened with Z-shaped incisions.

Combined and adjunctive procedures are performed as complementary methods in nasal valve repair. Septoplasty and turbinate reduction are generally performed together. Radiofrequency treatment is a minimally invasive method preferred for less severe cases. The surgical approach is determined according to the patient’s anatomical structure and needs. The preoperative preparation process is supported by nasal endoscopy and imaging techniques, allowing the surgeon to optimize the surgical plan.

What Is the Recovery Process After Nasal Valve Stenosis Surgery?

The recovery process after nasal valve stenosis surgery consists of several stages that must be carefully managed. Patients generally return home on the same day after surgery.

Postoperative Care:

• Remaining under observation for the first few hours
• Resting at home

Mild pain and discomfort are normal during the first 36-72 hours. Doctors may prescribe medications to relieve the pain.

Pain and Discomfort Management:

• Prescription painkillers
• Rest

Swelling and bruising around the nose may occur during the first week. Cold compresses may be applied to relieve these symptoms.

Swelling and Bruising:

• Applying cold compresses
• Sleeping with the head elevated

Nasal hygiene is an important part of the healing process. Saline sprays should be used to keep the nasal passages open and prevent crusting.

Nasal Hygiene:

• Saline sprays
• Avoiding blowing the nose

It is important to avoid excessive activity during the first few weeks of recovery. It is recommended to sleep with the head elevated and avoid movements such as heavy lifting.

Activity Restrictions:

• Resting
• Avoiding strenuous exercise

Regular follow-up appointments after surgery are critically important to ensure that the healing process is progressing correctly.

Follow-Up Appointments:

• Monitoring recovery
• Regular consultations with the doctor

During the later weeks of recovery, daily activities may gradually be resumed with the doctor’s advice. The use of saline sprays and prescribed ointments, if any, should be continued.

Ongoing Care:

• Returning to light activities
• Using moisturizing sprays

What Are the Risks and Complications of Nasal Valve Stenosis Surgery?

Nasal valve stenosis surgery aims to correct the nasal structure and improve respiratory function. However, this procedure also carries certain risks and complications. The surgery includes general and specific risks:

General Surgical Risks:

• The risk of infection exists in every surgical procedure.
• Bleeding may occur during and after surgery.
• General anesthesia may cause allergic reactions and respiratory problems.

Specific Risks and Complications:

• Internal and external scars may form; these scars may lead to both aesthetic and functional problems.
• There is a possibility of septal perforation, and this condition may require additional surgery.
• Regional numbness or loss of sensation may occur.
• Postoperative pain and discomfort can generally be controlled with medication.
• Swelling and bruising are a natural part of the healing process and decrease within a few weeks.
• Nasal congestion or discharge may be observed during the initial healing period.

Functional and aesthetic concerns are among the important outcomes of this procedure:

• Some patients may continue to experience nasal congestion or difficulty breathing after surgery.
• The surgery may change the aesthetic appearance of the nose.
• Scar tissue formation or persistent nasal valve collapse may require additional interventions.

Long-Term Complications:

• The nasal valve may weaken again over time.

What Health Problems Can Untreated Nasal Valve Stenosis Cause?

If nasal valve stenosis is left untreated, it may lead to serious health problems. These health problems arise as direct consequences of airway obstruction. Without treatment, individuals’ quality of life decreases significantly.

• Chronic Nasal Congestion: It makes breathing difficult and becomes particularly noticeable while lying down or during physical activities.
• Mouth Breathing: It may lead to dry mouth, sore throat, and dental problems.
• Sleep Disorders: Conditions such as snoring and obstructive sleep apnea may develop, which threaten cardiovascular health.
• Reduced Exercise Capacity: Physical performance decreases because air inhaled through the nose provides oxygen to the body more efficiently.
• Frequent Sinus Infections: Frequent infections develop as a result of improper sinus drainage, causing facial pain and headaches.
• Voice and Speech Problems: Difficulty speaking clearly and reduced voice resonance may occur.
• Changes in Facial Structure: Prolonged mouth breathing may cause structural changes in the face and jaw, especially in children.
