Sinus Cavity

Sinusitis occurs when the sinus cavities are unable to properly drain mucus, which results in an inflammation of the sinus cavity. The disease is primarily classified into three types: acute, recurrent and chronic.

Acute sinusitis lasts less than four weeks and is often caused by excess or thick mucus. In general, acute sinusitis is treated with medical management.

Recurrent acute sinusitis is characterized by more than four episodes of acute sinusitis per year.

Chronic sinusitis is the most severe form of sinusitis and lasts more than 12 weeks per year. Otolaryngologists further classify their chronic sinusitis patients into those with nasal polyps and those without nasal polyps.

In addition, there are additional sinus conditions, including:

Barosinusitis: a swelling or inflammation of the lining of one or more of the sinuses due to a change in air pressure.

Sinogenic headache (also known as sinus headache): persistent or recurring headaches as a result of mucosal contact points within the nasal cavity.

HIGHLY PREVALENT DISEASE Chronic sinusitis is one of the most prevalent chronic conditions among adults in the U.S. The prevalence rates vary by source from approximately 5%-15% of the adult population. The Centers for Disease Control (CDC) estimates that chronic sinusitis occurs in approximately 12% of the U.S. adult (18 years and older) population. In 2015, there were an estimated 29 million adult chronic sinusitis patients in the U.S. There were approximately six million pediatric chronic sinusitis patients in the U.S. in 2015. While some clinicians believe pediatric chronic sinusitis patients should be left untreated, clinical studies have shown that pediatric patients with chronic sinusitis have a significantly reduced quality of life as compared to selected other diseases.


Many chronic sinusitis patients progress slowly through the treatment continuum. When symptoms first present, patients often seek care from their primary care physician or PCP. These physicians typically prescribe or recommend over the counter (OTC) medications, such as decongestants, nasal and systemic steroids, mucolytics and irrigation.

As symptoms persist and possibly worsen, patients are often referred to more specialized physicians, such as otolaryngologists and/or allergists, who are then able to diagnose chronic sinusitis via endoscopic imaging.

Following multiple rounds of medication, it is estimated that approximately 60% of patients remain symptomatic and may be optimal candidates for a more invasive treatment option.


Functional endoscopic sinus surgery (FESS) is the preferred surgical treatment option for chronic sinusitis patients. FESS is traditionally performed in a hospital operating room and involves the removal of the inflamed sinus tissue, as well as the underlying bone to open the nasal pathway and enlarge the sinus ostia. The surgeon can also perform additional procedures if needed to treat nasal deformities or to gain access to the sinuses.

The three most common sinus surgery procedures include ethmoidectomy, maxillary antrostomy and powered septoplasty with turbinoplasty.

Ethmoidectomy: aids in clearing the ethmoid sinuses. Maxillary antrostomy: enables the maxillary sinuses to drain more efficiently and effectively. Powered septoplasty with turbinoplasty: involves the clearing of breathing difficulties caused by a deviated or displaced nasal septum that causes one nasal passage to be smaller than the other or enlarged turbinates, which clean and humidify the air as it transitions from the nose to the lungs.

When the surgical procedure is complete, the surgeon fills the nasal cavity with packing materials that aid in preventing surgical adhesions and controlling bleeding. In addition, patients often require at least one (if not multiple) follow-up visits for debridement, whereby the surgeon removes damaged tissue from the body.

Some Drawbacks to Surgery Remain

While FESS is the standard of care in the surgical treatment of chronic sinusitis, it does carry a host of risks and selected drawbacks.

Selected Drawbacks, Traditional Sinus Surgery (FESS)
  • Irreversible changes to the patient’s underlying anatomy.
  • Post-operative pain and discomfort, including that of follow-up debridement procedures.
  • Recovery time of approximately 2-3 days.
  • General anesthesia risks, such as excessive bleeding and intraorbital complications.
  • Surgical complications, including eye swelling or blindness (though quite rare, occurring in approximately 1% of all FESS procedures).

In addition, while sinus surgery is effective in the majority of patients, it is estimated that approximately 10% of FESS patients will require revision surgery with more than 60% of patients experiencing recurrent symptoms within the first year of the FESS procedure.

Balloon sinus dilation was introduced in 2005 as a minimally invasive alternative to functional endoscopic sinus surgery (FESS) in patients with chronic sinusitis. Balloon sinus dilation can be used to treat the maxillary, frontal and sphenoid sinuses but not the ethmoid sinuses. The procedure uses a balloon catheter to remodel and widen the sinus passageway and generally takes approximately one hour.


The Sinusleeve® Balloon is intended to be used with commonly used ENT instruments to dilate the sinus ostia and spaces within the maxillary, frontal and sphenoid paranasal sinus cavities. The Sinusleeve® Balloon is compatible with commonly used suction instruments, including instruments with the latest image guided navigation capability.

There are many advantages to using the Sinusleeve® Balloon during hybrid procedures.

  • Adapts common surgical instruments for balloon dilation
  • Performs dual functions simultaneously
  • Provides surgeon with surgical options
  • Provides adequate reach for optimum positioning
  • Versatile to use as situation demands

Sinus ostial dilation (e.g. balloon ostial dilation) is a therapeutic option for selected patients with chronic rhinosinusitis (CRS) and recurrent acute rhinosinusitis (RARS) who have failed appropriate medical therapy. Clinical diagnosis of CRS and RARS should be based on symptoms of sinusitis and supported by nasal endoscopy documenting sinonasal abnormality or mucosal thickening on computed tomography of the paranasal sinuses. This approach may be used alone to dilate an obstructed sinus ostium (frontal, maxillary, or sphenoid) or in conjunction with other instruments (eg, microdebrider, forceps). The final decision regarding use of techniques or instrumentation for sinus surgery is the responsibility of the attending surgeon.
