Nasal Obstruction

1. What is the condition about?

Nasal Obstruction refers to a common medical issue characterized by the partial or complete blockage of the nasal passages, leading to difficulties in breathing through the nose. This condition can significantly impact a person’s quality of life, affecting their ability to breathe, sleep, and function normally.

2. What are the causes?

Common Causes of Nasal Obstruction:
  • Structural Abnormalities: Deviated septum, nasal polyps, or other anatomical irregularities can obstruct the nasal passages.
  • Infections: Sinus infections, colds, or allergies can lead to nasal congestion and obstruction.
  • Allergies: Allergic reactions to pollen, dust, pet dander, or mold can cause inflammation and blockage of the nasal passages.
  • Nasal Turbinate Enlargement: The turbinates, structures inside the nose responsible for humidifying and filtering the air, can become enlarged and obstruct the airflow.
  • Trauma: Previous injuries or accidents can result in a deviated septum or other structural issues leading to obstruction.
Understanding the underlying cause of nasal obstruction is crucial for determining the most appropriate treatment.

3. How common is the condition?

Nasal obstruction is a prevalent condition that affects a significant portion of the population. Its prevalence can vary based on geographic location, environmental factors, and the population’s overall health.

Global Prevalence:

  • Nasal obstruction is one of the most common complaints seen by Ear, Nose, and Throat (ENT) specialists worldwide.
  • In Singapore, nasal obstruction is a frequent reason for patients to seek medical attention, particularly due to the prevalence of environmental allergens.

Risk Factors: Certain risk factors, such as a history of allergies, sinus issues, or previous nasal trauma, may increase an individual’s susceptibility to nasal obstruction.

4. What can an ENT Specialist do for you?

Consulting with an ENT specialist is essential for the accurate diagnosis and effective management of nasal obstruction.

The Role of an ENT Specialist:

Accurate Diagnosis

ENT specialists have the expertise and specialized equipment to accurately diagnose the underlying causes of nasal obstruction, including structural abnormalities, infections, and allergies.

Treatment Planning

After a thorough evaluation, an ENT specialist can develop a personalized treatment plan tailored to the patient’s specific condition and needs. This may include medication, lifestyle modifications, or surgical options.

Minimally Invasive Procedures

ENT specialists are trained in performing minimally invasive procedures to address structural issues that may be causing nasal obstruction, such as septoplasty or turbinate reduction.

Long-Term Care

ENT specialists provide ongoing care and monitoring to ensure the best possible outcomes. They can also address any complications or recurrent issues effectively.

Consulting with an ENT specialist ensures that patients receive the most appropriate and advanced care for their nasal obstruction, potentially leading to improved quality of life and breathing comfort.

5. How can the condition be treated?

The treatment of nasal obstruction depends on its underlying cause, severity, and duration. Various treatment options are available, ranging from conservative approaches to surgical interventions.

Treatment Options for Nasal Obstruction:


For mild cases, medications such as decongestants, antihistamines (for allergies), and nasal corticosteroids can provide temporary relief from nasal congestion.

Lifestyle Modifications

Lifestyle changes, such as avoiding allergens, using humidifiers, and practicing good nasal hygiene, can help alleviate symptoms and prevent recurrence.

Nasal Polyps
Minimally Invasive Procedures

Surgical options, such as septoplasty (to correct a deviated septum) or turbinate reduction (to address enlarged turbinates), can be performed by ENT specialists to improve nasal airflow and alleviate obstruction.

Balloon Sinuplasty

In cases where sinus issues contribute to nasal obstruction, Balloon Sinuplasty may be recommended to open blocked sinus passages and improve airflow.

Traditional Nasal Surgery

For severe or complex cases, traditional nasal surgery may be necessary to address structural abnormalities or other underlying issues contributing to nasal obstruction.

The choice of treatment, whether conservative or surgical, should be made in consultation with an ENT specialist after a comprehensive evaluation of the patient’s condition and needs.

6. Guidelines for Surgery

When nasal obstruction cannot be effectively managed through conservative measures or minimally invasive procedures, surgical intervention may be recommended. Here are some important guidelines to consider when contemplating surgery for nasal obstruction:

Pre-operative Preparations:

  • Consultation: Schedule a thorough consultation with an ENT specialist to discuss your symptoms, medical history, and the need for surgery.
    • Diagnostic Tests: Your specialist may recommend imaging tests, such as CT scans, to assess the nasal anatomy and identify the exact cause of obstruction.
  • Medical Evaluation: Complete any necessary medical evaluations and provide a list of current medications, allergies, and medical conditions.
  • Anesthesia: Discuss anesthesia options and potential risks with your surgical team.
  • Fasting: Follow fasting instructions provided by your healthcare providers to prepare for surgery.

The Surgical Procedure:

  • Anesthesia: Depending on the type of surgery and your individual needs, you may undergo either local or general anesthesia.
  • Surgical Techniques: The surgeon will use specialized techniques based on the cause of your nasal obstruction. For example, septoplasty may be performed to correct a deviated septum, while turbinate reduction can address enlarged turbinates.
  • Recovery: After the procedure, you’ll be monitored in a recovery area. Most nasal surgeries are performed on an outpatient basis, allowing you to return home the same day.

7. Evaluation & Follow Up for Treatment

Following nasal surgery, thorough evaluation and follow-up care are essential for a successful recovery and optimal results.

Post-treatment Care
  • Home Recovery: You will receive specific instructions for post-operative care, including wound care, pain management, and any necessary medications.
  • Follow-up Appointments: Attend all scheduled follow-up appointments with your ENT specialist. During these visits, the surgeon will assess your healing progress, address any concerns, and remove any nasal packing or sutures if used.
  • Monitoring: Your specialist will monitor your condition to ensure that the surgical goals have been achieved and that you are experiencing improved nasal airflow.
Long-term Care:
  • Nasal Hygiene: Continue practicing good nasal hygiene as advised by your ENT specialist to maintain optimal sinus health.
  • Allergy Management: If allergies were a contributing factor to your nasal obstruction, follow your specialist’s recommendations for allergy management to prevent recurrence.
  • Lifestyle Modifications: Make necessary lifestyle changes, such as avoiding smoking or irritants, to support ongoing nasal health.

8. Risks of Surgery

While nasal surgery is generally safe and effective, it is essential to be aware of potential risks and complications associated with any surgical procedure.

Possible Risks and Complications:

  • Bleeding: Some bleeding is common during and after surgery but is typically temporary and manageable.
  • Infection: Infections are rare but possible; prompt treatment is essential to prevent complications.
  • Scarring: Surgical procedures may result in minimal scarring, but this is usually inconspicuous.
  • Changes in Sensation: Some individuals may experience temporary changes in sensation, such as numbness or altered sense of smell, which typically improve over time.
  • Recurrence: In some cases, nasal obstruction symptoms may return, necessitating additional treatment or adjustments to the initial procedure.

Discuss any concerns or questions regarding potential risks with your ENT specialist before undergoing surgery.

9. Alternatives to Surgery

In some cases, surgery may not be the first-line treatment or may not be suitable for certain individuals. Alternatives to surgery should be considered based on the specific cause and severity of nasal obstruction.

Alternative Treatment Options:

  • Medications: Medications such as decongestants, antihistamines, and nasal corticosteroids may provide relief from nasal congestion and related symptoms.
  • Lifestyle Modifications: Lifestyle changes, including allergen avoidance and good nasal hygiene, can help manage mild nasal obstruction symptoms.
  • Minimally Invasive Procedures: For individuals who are not candidates for traditional surgery, minimally invasive procedures like Balloon Sinuplasty may be an alternative option.

The choice of treatment, whether surgical or non-surgical, should be made in consultation with an ENT specialist after a comprehensive evaluation of your condition and individual needs. Your specialist will help determine the most appropriate and effective treatment plan to provide long-lasting relief from nasal obstruction.
