NCT02812199

Brief Summary

This is a randomized controlled first in man study. Study purpose is to assess safety and efficacy of Composite Removable Stent Composite Stent implantation post-endoscopic sinus surgery in terms of:

  • Sinus tissue adhesions
  • Middle turbinate lateralization into nasal septum i.e. postoperative opening reduction
  • Inflammation

Outcome Measures

Primary Outcomes (1)

  • Composite Removable Sinus Stent efficacy compared to standard of care

    The primary objective of this study is to assess Composite Removable Stent efficacy following FESS surgery compared to standard of care, in terms of inflammation, adhesion s, middle turbinate position, and patient symptoms improvement assessed by SNOT-22 questioner.

    12 weeks

Secondary Outcomes (1)

  • Pain associated with Composite Stent removal vs. standard of care removal

    4 weeks

Other Outcomes (1)

  • Patient discomfort

    4 weeks

Study Arms (3)

pilot study group 1

EXPERIMENTAL

Patients in pilot study group 1 will undergo post-FESS bilateral implantation of Composite Removable Sinus Stent into middle meatus. Nasal tampon will be placed to stop bleeding if necessary. Patients in pilot study group scheduled for 6 follow up visits at 1,2,3,4,6 and 12 weeks after implantation and for tampon removal at day 2 - 3 after FESS surgery. Stent will be removed between 14 and 28-day implantation. Before removal adrenaline - lidocaine administration will be used locally to minimize bleeding and cold saline wash applied to induce stent crimping.

Device: Composite Removable Sinus StentDrug: adrenaline-lidocaineProcedure: cold saline wash

study group 2

EXPERIMENTAL

Patients in study group 2 will undergo post-FESS bilateral implantation of Composite Removable Sinus Stent into middle meatus. Nasal tampon will be placed to stop bleeding if necessary. Patients in 2nd study group scheduled for 4 follow up visits at 2, 4, 6 and 12 weeks after implantation. Before removal adrenaline - lidocaine administration will be used locally to minimize bleeding and cold saline wash applied to induce stent crimping.

Device: Composite Removable Sinus StentDrug: adrenaline-lidocaineProcedure: cold saline wash

control group 3

NO INTERVENTION

control group patients will undergo post-FESS bilateral Standard of Care (tampon) placement into middle meatus as standard of care. Frontal tampon will be placed to stop bleeding. Patients in control group scheduled for 3 follow up visits at 2, 6 and 12 weeks after surgery and for tampon removal at day 2 - 3 after FESS surgery.

Interventions

Post-FESS bilateral implantation of sinus stent into middle meatus. Nasal tampon will be placed to stop bleeding. Stent will be removed after 14 - 28-day implantation, during self-crimp procedure induced by cold saline flush and safely pulled out. During implantation period patients will be examined endoscopically for inflammation, adhesions and middle turbinate position.
