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, trapping secretions and sustaining inflammation. Balloon sinuplasty targets that obstruction mechanically. The US Food and Drug Administration cleared balloon catheters for nasal sinus use in 2005, and the technique has since become a common alternative to tissue-removing endoscopic surgery in appropriately selected patients.
The procedure suits sinuses that are single-cell structures with a discrete opening: the maxillary, frontal, and sphenoid sinuses. The ethmoid air cells are multicellular and are not amenable to balloon dilation, so disease centered there is addressed by other means. Candidacy rests on computed tomography evidence of sinus disease together with symptoms that have persisted despite medical management.
Reported outcomes are favorable in selected patients. The CLEAR study found 80.5% of treated sinuses remained patent at 24 weeks, and reported symptom improvement of 85% at one week, 98% by 12 weeks, and 80% at 24 weeks. A prospective series of 20 patients followed for 12 months recorded mean SNOT-20 scores falling from 68.60% before surgery to 38.20% in the first postoperative week and 16.65% at one year, with no restenosis or scarring observed during the follow-up period.
The overall complication rate reported across the literature is 5.26%, comprising 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 recovery is about 4 days for balloon dilation and 14 days for functional endoscopic sinus surgery. Debate continues within the field about the precise indications and about 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. When mucosal swelling or bony narrowing obstructs that opening, mucus is retained, ventilation falls, and inflammation persists.
- A balloon catheter placed across the obstructed ostium and inflated to between 8 and 12 atmospheres widens the outflow tract by microfracturing the thin surrounding bone. The bone remodels in its dilated position once the balloon is withdrawn.
- Because the dilation displaces bone and does not resect tissue, the mucosal lining of the ostium stays intact. Preserving that lining preserves mucociliary clearance, the mechanism by which the sinus sweeps mucus toward the opening.
- Restoring patency allows the sinus to ventilate and drain, which reduces the retained secretions and the 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 are different obstructions that present as one complaint. The septum, the turbinates, and the internal valve govern airflow through the nose; the ostia govern drainage out of the sinuses, and a balloon dilates the second without touching the first. Dr. Banthia holds board certification in otolaryngology-head and neck surgery as well as in facial plastic and reconstructive surgery, so both are examined at the same visit and a patient is not sent between two practices to find out which one they have.
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 using a small balloon catheter. Under endoscopic guidance, the balloon is positioned across the sinus opening and inflated, widening the drainage pathway by microfracturing the surrounding bone while leaving the mucosal lining intact.
- Functional endoscopic sinus surgery removes obstructing tissue and bone, which lets it address ethmoid disease and nasal polyps. A balloon removes nothing: it dilates the natural opening by microfracturing the thin bone around it, and the mucosal lining that sweeps mucus toward the opening stays intact, so it applies only to the maxillary, frontal, and sphenoid sinuses. Reported average recovery is about 4 days after balloon dilation and about 14 days after functional endoscopic sinus surgery, and the two are sometimes combined in one operation. Candidacy rests on what the CT shows rather than on how bad the symptoms feel, and Dr. Banthia goes through the imaging at the consultation – including the cases where the answer is neither operation.
- It can. In-office balloon dilation is performed with topical and injected local anesthesia and light sedation, which avoids general anesthesia and its associated risks. The same procedure is also performed in an operating room under general anesthesia or conscious sedation, and the setting is chosen based on the anatomy, the number of sinuses treated, and patient factors.
- Most patients rest at home for 24 to 48 hours and avoid blowing their nose during that time. Mild bloody drainage and a feeling of pressure are common in the first days. Nasal packing is often unnecessary because no tissue has been removed, and most people return to normal activities within one to two weeks.
- The overall complication rate reported across the literature is 5.26%, made up of orbital complications at 2.95%, bleeding at 2.03%, and skull base injury at 0.35%. Cerebrospinal fluid leak has been documented as a rare event. These are the same categories of risk that apply to sinus surgery generally, and a surgeon reviews them against the individual anatomy during consultation.
- Balloon dilation is not appropriate for chronic rhinosinusitis with nasal polyps, for disease centered in the ethmoid air cells, or for patients with cystic fibrosis, allergic fungal sinusitis, or suspected sinonasal malignancy. It is also not indicated without computed tomography evidence of sinus disease, or for a patient without symptoms.
- In the CLEAR study, 80.5% of treated sinuses remained patent at 24 weeks, and reported symptom improvement was 80% at that point. Revision has been reported in 7.89% of patients treated with balloon dilation alone. Symptoms can recur, and repeat dilation or a move to endoscopic sinus surgery is then considered.
- Possibly not, and that is worth establishing before anything is scheduled. Persistent nasal blockage more often comes from a deviated septum, enlarged turbinates, or a collapsing internal valve than from sinus drainage, and none of those is treated by dilating an ostium. Dr. Banthia examines the nasal airway and the sinuses together; rhinoplasty covers the structural side of the nose, including the functional work done for breathing alone.
- The maxillary, frontal, and sphenoid sinuses, each of which is a single chamber with one discrete opening a balloon can be threaded into. The ethmoid air cells are a honeycomb of small chambers and cannot be dilated this way, so disease centred there is addressed by other means. Dr. Banthia confirms which sinuses are involved from the CT before offering the procedure, because the imaging decides candidacy more than the symptoms do.
