The study is designed to evaluate if addition of the steroid to the spacer / stent will improve healing after endoscopic sinus surgery (ESS) compared to spacer without drug.

Condition Intervention
Device: steroid eluting spacer

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Intervention Model Description:
Subjects undergoing endoscopic sinus surgery (ESS) will receive one steroid eluting spacer placed into the surgical site on one side, and one spacer without steroid placed on the other side.
Masking: No masking
Masking Description:
At the end of surgery, the Surgery Fellow will insert either the Drug Eluting Spacer or the Silastic spacer into each side of the subject's nose. The subject will receive one of each spacer. The fellow will record which spacer was placed on which side using a special coding system to keep this information private. This maintains the blinding for the primary surgeon/outcome assessor and subject.
Primary Purpose: Treatment
Official Title: Rates of Middle Meatus (MM) Synechiae Formation Post Endoscopic Sinus Surgery (ESS)

Primary Outcome Measures:
  • Incidence of middle meatal synechiae [ Time Frame: 90 days ]
    Safety and effectiveness of steroid eluting spacer will be measured by incidence of 35 and 90-day post Functional Endoscopic Sinus Surgery (FESS) incidence of middle meatal synechiae.

Secondary Outcome Measures:
  • sinonasal mucosal inflammation [ Time Frame: 90 days ]
    35 and 90-day sinonasal mucosal inflammation will be assessed by rigid endoscopy and graded on both the Philpott-Javer and Modified Lund-Kennedy sinus mucosal endoscopic staging systems

  • intraocular pressure (IOP) [ Time Frame: 90 days ]
    35 and 90-day intraocular pressure (IOP) will be assessed using applanation tonometry and compared to baseline IOP obtained preoperatively

  • postoperative interventions [ Time Frame: 35 days ]
    35-day frequency of postoperative interventions, including lyses of adhesions and debridement.

  • SNOT-22 Questionnaire [ Time Frame: 90 days ]
    90-day validated Sinonasal Outcomes Test-22 (SNOT- 22) scores

Enrollment: 10

Arms Assigned Interventions
Experimental: Steroid Eluting Spacer

Subjects will receive one steroid eluting spacer (Restora Mometasone Furate Eluting Spacer) placed into the surgical site on one side, and one spacer without drug (Silastic spacer) placed on the other side.

The Restora Mometasone Furate Eluting Spacer will be compared to the Silastic spacer.

Device: steroid eluting spacer
The Restora Mometasone Furate Eluting Spacer will be compared to the Silastic spacer.

Detailed Description:

The study is designed to evaluate basic device usability and confirm safety and effectiveness of the Restora Steroid Eluting spacer compared to a Silastic spacer.

At the completion of their procedure, patients undergoing ESS will receive one steroid eluting spacer placed into the surgical site on one side, and one spacer without drug placed on the other side. Patients will return for standard post-op visits. Between post-op day 6 and 8, both spacers will be removed. Patients will again be seen on post-op day 35 and 90 to evaluate the surgical sites with respect to healing, scarring, infection, degree of inflammation, polyp formation, and the need for secondary intervention. Data from the two sides will be compared to determine if there is a benefit derived from the spacer with steroid vs the one without.
