Balloon Sinus Dilation
Chronic sinus symptoms can make everyday life uncomfortable. Ongoing congestion, facial pressure, postnasal drip, and difficulty breathing through the nose may interfere with sleep, work, exercise, and daily activities.
​
At OC ENT & Sinus, Dr. Michael Kim evaluates patients experiencing chronic sinus concerns and offers a range of treatment options, including balloon sinus dilation — a minimally invasive procedure designed to help improve sinus drainage and reduce chronic sinus symptoms in appropriate candidates.
Understanding Chronic Sinusitis
Your sinuses are air-filled spaces located within the bones of the face. Normally, mucus drains naturally through small sinus openings. When inflammation develops, these drainage pathways can become blocked.
This may lead to symptoms such as:
-
Chronic nasal congestion
-
Facial pressure or fullness
-
Headaches
-
Postnasal drip
-
Difficulty breathing through the nose
-
Recurrent sinus infections
-
Reduced sense of smell
Sinus inflammation may be associated with allergies, infections, nasal polyps, structural concerns, or environmental irritants.
What to Expect During the Procedure
Balloon sinus dilation is typically performed in the office using local anesthesia to help keep patients comfortable.
During the procedure:
-
A small balloon catheter is guided into the sinus opening.
-
The balloon is gently expanded to widen the blocked pathway.
-
The balloon is then removed, leaving the sinus opening enlarged to support drainage.
​
Procedure times vary depending on the patient’s anatomy and treatment plan. Many patients are able to return home shortly after the procedure and resume normal activities within a short period of time, depending on individual recovery.
Recovery After Procedure
Recovery experiences vary from patient to patient. Some individuals may experience mild congestion, pressure, or drainage during the healing process.
-
Post-procedure recommendations may include:
-
Saline nasal rinses
-
Temporary activity restrictions
-
Follow-up visits
-
Medications to reduce inflammation when appropriate
Our team provides individualized recovery instructions based on your specific treatment plan.

-

What Is Balloon Sinus Dilation?
Balloon sinus dilation, sometimes referred to as balloon sinuplasty, is an in-office procedure used to gently open blocked sinus pathways.
​
During treatment, a small balloon catheter is inserted into the sinus passage and carefully expanded to help improve drainage while preserving surrounding tissue. The procedure is minimally invasive and does not typically involve cutting or removing bone or tissue.
​
Balloon sinus dilation may be recommended for certain patients with chronic or recurrent sinus symptoms that have not improved with conservative treatment.

Who May Be a Candidate for Balloon Sinus Dilation?
Patients experiencing ongoing sinus symptoms despite medication or other conservative therapies may benefit from an ENT evaluation.
You may be a candidate if you experience:
-
Chronic sinusitis
-
Recurrent sinus infections
-
Persistent congestion
-
Facial pressure
-
Nasal drainage or postnasal drip
-
Difficulty breathing through the nose
At OC ENT & Sinus, we perform a comprehensive evaluation that may include imaging and nasal examination to determine the most appropriate treatment plan for your condition.
Antihistamines, nasal corticosteroid sprays, and decongestants (short-term use) may help inflammation and reduce symptoms.
Allergy testing may be recommended to help identify specific triggers contributing to your symptoms. This information can be used to guide treatment and avoidance strategies. For some patients, finding out what they’re allergic to is necessary for preventing potentially life-threatening reactions, such as allergies to bee stings or nuts.
Immunotherapy may be recommended for some patients with persistent allergy symptoms. This treatment involves gradually exposing the body to small amounts of allergens over time, which may help reduce sensitivity. It is typically considered when symptoms are not well-controlled with medications or avoidance strategies.
In some cases, additional in-office treatments may be considered to help manage chronic nasal symptoms related to allergies. These options are typically recommended based on individual evaluation and symptom severity.
Frequently Asked Questions
Is balloon sinus dilation surgery?
Balloon sinus dilation is considered a minimally invasive sinus procedure and is often performed without traditional surgical incisions.
Is the procedure painful?
Your provider will discuss anesthesia, comfort measures, and possible discomfort during your consultation.
How long does recovery take?
Recovery varies by patient, though many individuals are able to return to normal routines relatively quickly.
Will insurance cover balloon sinus dilation?
Coverage depends on your insurance provider and medical necessity requirements. Our office can help review your benefits and discuss coverage options.
How long do results last?
Results vary based on the individual patient and the underlying cause of sinus symptoms.
In addition to medical treatment, certain lifestyle adjustments may help reduce exposure to triggers such as:
-
Keeping windows closed during high pollen seasons
-
Using air filtration systems
-
Washing bedding regularly
-
Avoiding known irritants such as smoke
These steps may help improve symptom control when combined with treatment.
-
You may consider seeking evaluation if symptoms are persistent or worsening, over-the-counter treatments are not effective, symptoms interfere with sleep or daily activities, or you are unsure of the cause of your symptoms.
Dr. Kim commonly uses skin and blood tests for allergy testing. Skin tests include skin patch tests, skin prick tests, and intradermal tests. Oral food challenges and elimination diets may be used to test for food allergies.
Seasonal Allergies
Allergies that occur during specific times of the year, often related to pollen exposure.
Perennial Allergies
Allergies that occur year-round and are typically associated with indoor allergens.
Non-Allergic Rhinitis
Involves similar symptoms but is triggered by irritants rather than an immune response.
Pollen
Trees, grasses, and weeds
Dust Mites
Common in bedding and upholstery
Mold
Found in damp indoor or outdoor environments
Pet Dander
Skin cells and saliva from animals
Irritants
Smoke, pollution, or strong odors
