Chronic sinusitis is constant inflammation of the sinus caused by infection or allergy and characterized by facial pain and pressure, nasal congestion, and headaches. When drug treatments fail, functional endoscopic sinus surgery (FESS) is performed to improve airflow within the nose and sinuses, improve drainage, and eliminate diseased tissue.
Unfortunately, up to 30% of sinus surgeries fail due to scarring and recurrent inflammation that closes the nasal openings and requires revision sinus surgery. The market seeks a safe and effective solution that will reduce the need for revision surgery.
STstent is a device implanted into a patient after FESS (functional endoscopic sinus surgery) to eliminate postoperative complications and revisions surgery. It keeps the sinus cavity open up to 28 days, long enough for the sinus tissue to heal. It adapts to the anatomy and does not migrate all the while providing strong, stable support of sinus walls. Made of biocompatible materials, it does not irritate the internal tissue. STstent not only improves the quality of life of patients but also reduces significantly costs for healthcare providers.
