STStent

S.T.Stent has developed a composite removable sinus stent. The FDA-cleared stent is designed to be placed into ethmoid sinus following functional endoscopic sinus surgery (FESS) to maintain the cavity open. FESS procedure is used to treat chronic sinusitis, which is one of the most common health problems in the modern world. However a single surgery often is not enough to cure the patient, due to post surgery scarring, stenosis and middle turbinate lateralization. The stent is designed to keep the cavity open, long enough for the healing process to complete itself and can be removed at any time, based on patient decision or physician consult. Stent removal is an in-office procedure, done without anesthesia, and is minimally invasive for the patient.

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 (RSNA RadioGraphics).
