PARANASAL SINUSESSURGICAL
Balloon Sinuplasty in Murrieta
Balloon sinuplasty is a minimally invasive endoscopic procedure that widens a blocked sinus opening using a small balloon catheter. Under endoscopic guidance, a guide catheter and guidewire are advanced into the natural ostium of the sinus, and a balloon is inflated to microfracture and remodel the bony outflow tract, restoring ventilation and drainage. The technique preserves the overlying mucosa and its mucociliary function, and it can be performed in an office setting under local anesthesia with sedation or in an operating room.
At a Glance
- Balloon catheters were cleared by the FDA for nasal sinus use in 2005 and dilate the ostium by microfracturing the bony outflow tract while preserving the overlying mucosa[1]
- The CLEAR study reported 80.5% of treated sinuses remained patent at 24 weeks, with symptom improvement in 98% of patients by 12 weeks[1]
- The overall reported complication rate is 5.26%, comprising orbital 2.95%, bleeding 2.03%, and skull base injury 0.35%[1]
- Only the maxillary, frontal, and sphenoid sinuses are suitable; the ethmoid air cells are multicellular and cannot be dilated with a balloon[1]
- Average recovery is approximately 4 days after balloon dilation compared with 14 days after functional endoscopic sinus surgery[1]
Overview
Chronic rhinosinusitis develops when the narrow drainage pathways of the paranasal sinuses become obstructed. Secretions become trapped, ventilation falls, and inflammation persists. Balloon sinuplasty addresses that obstruction by widening the natural sinus opening without removing tissue.
In 2005, the US Food and Drug Administration granted clearance for balloon catheters to be used in the nasal sinuses. Balloon dilation has since become a common alternative to tissue-removing endoscopic surgery for appropriately selected patients.
The procedure applies to the maxillary, frontal, and sphenoid sinuses, which are single-cell structures with discrete openings. The ethmoid sinuses consist of multiple small air cells and cannot be dilated with a balloon. Candidacy depends on computed tomography evidence of sinus disease together with symptoms that have persisted despite medical management.
Reported outcomes are favorable in selected patients. In the CLEAR study, 80.5% of treated sinuses remained patent at 24 weeks. Symptom improvement was reported in 85% of patients at one week, 98% by 12 weeks, and 80% at 24 weeks.
A prospective series followed 20 patients for 12 months. Mean SNOT-20 scores fell from 68.60% before surgery to 38.20% during the first postoperative week and 16.65% at one year. No restenosis or scarring was observed during the follow-up period.
Across the published literature, the reported overall complication rate is 5.26%, including orbital complications at 2.95%, bleeding at 2.03%, and skull base injury at 0.35%. Revision has been reported at 7.89% after balloon dilation alone and 16.85% after functional endoscopic sinus surgery. Average reported recovery is approximately 4 days after balloon dilation and 14 days after functional endoscopic sinus surgery. Debate continues about the procedure’s precise indications and the risk of overutilization.
What to expect
- Clinical evaluation with nasal endoscopy and review of symptom duration and prior medical therapy
- Computed tomography of the sinuses to confirm disease and map the anatomy of the target ostia
- Application of a topical decongestant, followed by injection of local anesthetic; general anesthesia or conscious sedation is used when the procedure is performed in an operating room
- Introduction of a rigid nasal endoscope for direct visualization of the nasal cavity
- Advancement of the guide catheter to the opening of the target sinus under endoscopic view
- Passage of the guidewire into the sinus, with position confirmed by transillumination or fluoroscopy
- Advancement of the balloon catheter over the guidewire and inflation to 8 to 12 atmospheres
- Deflation, a single reinflation, and withdrawal of the balloon
- Irrigation of the sinus through an irrigation catheter where indicated
- Endoscopic inspection of the dilated ostium and repetition of the sequence for any additional sinus
- Discharge with aftercare instructions, typically without nasal packing
How a balloon sinuplasty works
- Each paranasal sinus drains through a narrow natural opening called an ostium. Mucosal swelling or bony narrowing can obstruct that opening, causing mucus retention, reduced ventilation, and persistent inflammation.
- Under endoscopic guidance, a balloon catheter is positioned across the obstructed ostium and inflated to between 8 and 12 atmospheres. The pressure microfractures the thin surrounding bone and widens the outflow tract. After the balloon is withdrawn, the bone remodels in the dilated position.
- The balloon displaces bone rather than removing tissue, leaving the mucosal lining of the ostium intact. That lining supports mucociliary clearance, the process that moves mucus toward the sinus opening.
- Restoring patency allows the sinus to ventilate and drain. This reduces the retained secretions and inflammatory cycle that sustain chronic symptoms. Because no tissue is removed and no raw surfaces are created, postoperative adhesion formation is minimal and nasal packing is often unnecessary.
- A blocked nose and a blocked sinus can feel like the same problem, but they involve different anatomy. The septum, turbinates, and internal nasal valve govern airflow through the nose. The sinus ostia govern drainage from the sinuses. Balloon dilation treats the ostia without changing the septum, turbinates, or internal valve.
- Dr. Banthia is board-certified in otolaryngology-head and neck surgery and in facial plastic and reconstructive surgery. Both the nasal airway and the sinuses are examined at the same visit, so the patient is not sent elsewhere to determine which type of obstruction is present.
When it's recommended
- Chronic rhinosinusitis without nasal polyps that has persisted despite medical management, with computed tomography evidence of sinus disease
- Recurrent acute rhinosinusitis with computed tomography evidence of sinus disease
- Obstruction of the maxillary, frontal, or sphenoid sinus outflow tract
- Barosinusitis, where pressure change provokes sinus pain
- Adjunctive use alongside functional endoscopic sinus surgery, dilating selected ostia within a larger operation
- Sinus symptoms lasting more than 12 weeks that have not improved on antibiotics and other medical therapy

Recovery & aftercare
- Rest at home for the first 24 to 48 hours is typical
- Nose blowing is avoided during that initial period to protect the dilated ostium
- Mild bloody drainage and a sensation of pressure or congestion are common in the first days
- Nasal packing is often unnecessary, since no tissue has been removed
- Most patients resume normal activities within one to two weeks
- Average reported recovery is about 4 days, shorter than the roughly 14 days reported after functional endoscopic sinus surgery
- Saline irrigation and any prescribed medical therapy continue during healing
- Follow-up endoscopy assesses ostial patency and symptom response
Alternatives
- Continued medical management with intranasal corticosteroids, saline irrigation, and antibiotics where indicated
- Functional endoscopic sinus surgery, which removes obstructing tissue and bone and addresses ethmoid disease
- Hybrid surgery combining balloon dilation of some ostia with tissue removal at others
- Septoplasty or turbinate reduction when nasal airway obstruction is the dominant problem
- Allergy evaluation and treatment when allergic inflammation is driving the symptoms

Frequently Asked Questions
- Balloon sinuplasty is a minimally invasive procedure that opens a blocked sinus with a small balloon catheter. Under endoscopic guidance, the balloon is placed across the natural sinus opening and inflated. This widens the drainage pathway by microfracturing the surrounding bone while leaving the mucosal lining intact.
- Functional endoscopic sinus surgery removes obstructing tissue and bone, which allows it to address ethmoid disease and nasal polyps. Balloon sinuplasty removes nothing. It widens the natural opening by microfracturing the thin bone around it while preserving the mucosal lining that moves mucus toward the opening. It applies only to the maxillary, frontal, and sphenoid sinuses. Reported average recovery is approximately 4 days after balloon dilation and 14 days after functional endoscopic sinus surgery, and the procedures are sometimes combined. Candidacy depends more on the CT findings than on the severity of symptoms. Dr. Banthia reviews the imaging during the consultation, including cases in which neither procedure is appropriate.
- Yes. In-office balloon dilation is performed with topical and injected local anesthesia and light sedation, avoiding general anesthesia and its associated risks. The procedure can also be performed in an operating room under general anesthesia or conscious sedation. The setting depends on the anatomy, the number of sinuses being treated, and patient factors.
- Most patients rest at home for 24 to 48 hours and avoid blowing their nose during that period. Mild bloody drainage and a feeling of pressure are common during the first few days. Nasal packing is often unnecessary because no tissue has been removed. Most people return to normal activities within one to two weeks.
- The published literature reports an overall complication rate of 5.26%, including orbital complications at 2.95%, bleeding at 2.03%, and skull base injury at 0.35%. Cerebrospinal fluid leak has also been documented as a rare event. These are the same categories of risk that apply to sinus surgery generally. A surgeon reviews them against the individual anatomy during consultation.
- Balloon dilation is not appropriate for chronic rhinosinusitis with nasal polyps, disease centered in the ethmoid air cells, cystic fibrosis, allergic fungal sinusitis, or suspected sinonasal malignancy. It is also not indicated for an asymptomatic patient or when computed tomography shows no evidence of sinus disease.
- In the CLEAR study, 80.5% of treated sinuses remained patent at 24 weeks, and symptom improvement was reported in 80% of patients at that point. Revision has been reported in 7.89% of patients treated with balloon dilation alone. Symptoms can recur, after which repeat dilation or functional endoscopic sinus surgery may be considered.
- Possibly not, and that distinction needs to be established before anything is scheduled. Persistent nasal blockage more often comes from a deviated septum, enlarged turbinates, or a collapsing internal nasal valve than from impaired sinus drainage. Balloon dilation does not treat those structures. Dr. Banthia examines the nasal airway and the sinuses together. Rhinoplasty covers the structural side of the nose, including functional work performed for breathing alone.
- The maxillary, frontal, and sphenoid sinuses can be treated because each is a single chamber with a discrete opening into which a balloon can be threaded. The ethmoid air cells form a honeycomb of small chambers and cannot be dilated this way, so disease centered there is addressed by other means. Dr. Banthia confirms which sinuses are involved from the CT before offering the procedure because the imaging determines candidacy more than the symptoms do.
