Balloon Sinus Dilation is a procedure that ear, nose and throat surgeons may use for the treatment of blocked sinuses. Patients diagnosed with chronic sinusitis but not responding to medications may be candidates for sinus surgery. Balloon technology was initially cleared by the U.S. Food and Drug Administration in 2005 and is an endoscopic, catheter-based system for chronic sinusitis. It uses a balloon over a wire catheter to dilate sinus passageways. The balloon is inflated with the goal of dilating the sinus openings, widening the walls of the sinus passageway and restoring normal drainage.
Research according to groups such as Deutsche Bank show that in 2015 there were approximately 550,000 adult functional endoscopic sinus surgery (FESS) procedures performed in the US. These kinds of more recent studies show 85% of current FESS procedures could be well suited for either standalone balloon sinus dilation or a hybrid procedure. It is the availability of a minimally invasive alternatives such as balloon sinus dilation that can help benefit patients who are currently not willing to undergo more traditional forms of surgery for treating their chronic sinusitis. There is also evidence to support as much as 85% of nonsurgical patients could be eligible for a standalone balloon sinus dilation procedure.
Altogether, this results in a total adult patient population in access of 600,000 in the US alone. There is evidence to support that the patient population has only been 20% penetrated with another 125,000 balloon sinus dilation procedures.
Studies also seem to indicate demand for total balloon sinus dilation procedures will increase to as much as 28% in 2021. Much of the increased penetration will be driven by continued clinical data supporting the use of the technology, as well as continued medical society, clinician support and patient willingness for less invasive procedures.
