Balloon sinuplasty
A small balloon widens a sinus opening. Whether that helps depends on the disease behind your symptoms.
Watch what the balloon changes
The instrument enters through the nostril and approaches the sinus beside the nasal turbinates.
The balloon works at the drainage opening below the sinus, not inside the whole chamber.
The frontal sinus drains through a small opening below it.
This example follows a sinus in the forehead. The dashed box locates the opening shown in the enlarged view.

When is it worth discussing?
An ENT should connect your symptoms, examination, and CT findings before recommending a procedure.
When it may fit
- Confirmed chronic sinusitis that affects daily life despite appropriate care.
- Selected cases of repeated acute sinusitis, with supporting CT findings.
- A diseased sinus opening that can be treated by dilation, with realistic goals agreed with your ENT.
Chronic sinusitis requires symptoms for at least 12 weeks plus objective inflammation. Duration alone is insufficient. Treatment history matters, but there is no universal medication checklist everyone must complete before surgery. 2025 surgical guideline
When to reconsider balloon alone
- No sinus disease on CT, or headache or sleep apnea without diagnosed sinusitis.
- The proposed goal is to cure allergies or fix a deviated septum. Dilation does neither.
- Polyps, fungal disease, or certain bone changes require removal of disease and a more complete opening of the sinus.
Post-nasal drip alone does not establish which problem needs treatment. Ask what finding explains yours.
What changes with each approach?
| Approach | What it addresses | The tradeoff |
|---|---|---|
| Medical care | Inflammation and symptoms, using treatment matched to the diagnosis. | Avoids a procedure; may not control persistent disease. |
| Balloon dilation | A selected sinus opening, usually without removing tissue. | Can involve less recovery; cannot remove polyps or other diseased tissue. |
| Endoscopic sinus surgery | Opens affected sinuses and can remove tissue or disease. | Can address more extensive disease; aftercare depends on the operation. |
Balloon dilation can also be part of endoscopic surgery. Both may require ongoing medical treatment. Surgical guidance · Patient overview
What does the research actually show?
Improvement is plausible. Superiority is unproven.
A review included 18 studies, with seven in its pooled analysis. The measured symptom-score difference between balloon dilation and endoscopic surgery was smaller than the review’s threshold for a meaningful difference.
In everyday terms: selected patients can improve with either approach. The limited quality of the comparisons does not establish that balloon is better, or that the procedures are interchangeable for everyone.
Sinha et al. · Read the reviewLonger follow-up, with an important limitation.
A database study matched 2,112 patients in each group. Recorded repeat endoscopic sinus surgery rates over 10 years were 5.8% after balloon dilation and 6.3% after endoscopic surgery, without a statistically significant difference.
In everyday terms: another operation was recorded at similar rates. This was not a randomized trial, matching covered age and sex, and avoiding another operation does not prove that symptoms disappeared.
Hoying et al. · Read the studyThe procedure should match the disease.
The guideline emphasizes confirming the diagnosis, discussing expected benefit, and planning for long-term care. When polyps, fungal disease, or specified bone changes are present, dilation alone is insufficient.
Shin et al. · Read the guidelineRecovery and risks
It may be performed in an office with local anesthesia, sometimes with sedation, or in an operating room. Pressure or discomfort can occur.
Recovery is often shorter than with more extensive surgery, but time off, activity restrictions, and follow-up depend on the procedure and any additional work.
Risks include bleeding, infection, anesthesia reactions, persistent or returning symptoms, and rare injury around the eye or a cerebrospinal fluid leak. “Minimally invasive” does not mean risk-free.
Cleveland Clinic · Procedure and recoveryAsk your ENT
- Can you show me which sinus is diseased on my CT?
- Which of my symptoms is this expected to improve?
- Why balloon dilation instead of continued treatment or endoscopic surgery?
- Is this balloon alone, or are other procedures included?
- What are my recovery plan, ongoing treatment, and total out-of-pocket costs?
