Sinopsys Lacrimal Stent Study for Patients With Chronic Sinusitis or CRS

Paused · Not applicable

Conditions studied: Chronic Sinus Infection

In brief

A prospective, single arm, multicenter study designed to demonstrate that the Sinopsys® Lacrimal Stent can safely create transcaruncular access to the ethmoid sinus to enable sinus irrigation and reduce symptoms in patients with moderate to severe chronic rhinosinusitis.

You may qualify if…

The Investigator has determined that the potential study subject has moderate to severe chronic rhinosinusitis with ethmoid involvement:
Non-Contrast CT scan (coronal view) Total Zinreich Modified CT score of 10-41
Inflammation/ involvement of the ethmoid sinus with left and/or right anterior ethmoid and/or posterior ethmoid Zinreich Modified CT scores of 1-4
SNOT-22 total raw score ≥ 45
Meets the American Academy of Otolaryngology - Head and Neck Surgery (AAO-HNS) criteria for chronic rhinosinusitis (CRS) (Rosenfeld, et al., 2007): 90 days or longer of two or more of the following signs and symptoms: Mucopurulent drainage (anterior, posterior, or both) Nasal obstruction (congestion) Facial pain-pressure-fullness, or Decreased sense of smell AND inflammation is documented by one or more of the following findings: Purulent (not clear) mucus or edema in the middle meatus or ethmoid region Polyps in nasal cavity or the middle meatus, and/or Radiographic imaging showing inﬂammation of the paranasal sinuses
Has failed medical therapy (Rudmik, et al., 2016) defined as the following:
During the 90 days prior to enrollment, at a minimum:
One course of broad spectrum or culture directed oral antibiotic of at least 2 weeks duration 60 days of topical intranasal steroid therapy and; 30 days of saline irrigation
Age ≥ 22 years
Non-Contrast CT scan (coronal view) confirms depth of olfactory fossa is Keros classification type 1 or 2
The potential study subject is capable of understanding and executing written informed consent (IC) and questionnaires/diaries in English

You may not qualify if…

Sinus opacification score of <10 or > 41 measured using the Zinreich Modified CT scoring system
Isolated sinus disease evident on Non-Contrast CT scan that would be unlikely to respond to target ethmoid treatment (e.g., isolated sphenoid, maxillary or frontal disease)
Polyposis scored as 2 using the Modified Lund-Kennedy Score
Prior ocular and/or sinus surgery that alter the boney anatomy or violate/enter the orbit or sinus in a way that would render these structures "non-intact" (i.e. FESS). Minor procedures such as balloon sinus dilation (>30 days), septoplasty or turbinectomy are not exclusions.
Non-Contrast CT scan (coronal view) shows depth of olfactory fossa is Keros classification type 3
Prior surgical history, physical exam, nasal endoscopy and/or imaging studies that suggest significant craniofacial deformity (such as any facial anatomic abnormality from surgical intervention, trauma, and congenital or any other cause thus prohibiting adequate placement of the Sinopsys Lacrimal Stent
Presence of a sinonasal encepholocele as determined by Non-Contrast CT scan
Presence of active HEENT infection including acute dacryocystitis, with the exception of CRS infection
Febrile illness within 2 weeks of procedure and/or active pus from nose
Any sign of active ophthalmic disease, infection, or inflammation including the presence of severe ocular surface inflammatory disease as determined by ophthalmic and physical exam, which could be exacerbated by the presence of the device
Best Corrected Visual Acuity (BCVA) worse than 20/50
Dry Eye disease defined by the following:
Abnormal Tear Breakup Test (TBUT) (< 5 seconds) in either eye and
Corneal staining showing superficial punctate keratopathy of Grade 1 or higher in either eye at Screening Visit
Use of topical or systemic prescription ocular medications, except rewetting drops for contact lens-related discomfort, for the eye to treat an active ophthalmic disease at or within 14 days of screening and through procedure
Underlying medical condition that, in the opinion of the Investigator, would place the subject at high risk if IV sedation (MAC or monitored anesthesia care) were used during the procedure
Excessive ocular and/or adipose tissue that may obscure implanted device visualization and/or placement
Known allergies to silicone, TobraDex® (Tobramycin and Dexamethasone), procedural medications, and ophthalmic eye drops (required for routine eye exams)
Documented diagnostic history of Cystic Fibrosis
Documented history of migraines, cluster headaches, chronic daily headaches or other headaches unrelated to the sinus
Documented uncontrolled or poorly controlled seasonal or perennial allergies
Requires any amount of concurrent systemic steroid medication for chronic illness such as auto-immune diseases
Tobacco, marijuana and/or e-vape inhaler use either currently or during the last 90 days
Documented history of bleeding disorders, for example, von Willebrand's disease or hemophilia
Inability to stop thrombolytics or other anti-platelet medication prior to procedure day including but not limited to Coumadin (warfarin) for 5 days, Plavix (clopidogrel) for 3 days, ASA/NSAIDs/fish oil supplements for 10 days, Xarelto® (rivaroxaban) for 24 hours
