简要总结
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
详细描述
The purpose of this study is to assess Composite Removable Sinus Stent safety and efficacy implantation following FESS surgery compared to standard of care.
At first pilot stage, 3-6 patients will be enrolled to this study. At 2nd stage 19-27 additional patients will be enrolled to this study for statistical assurance.
In study group patients will undergo post-FESS bilateral implantation of Composite Removable Sinus Stent into ethmoid sinus under same anesthesia. Stent is inserted upon low pressure balloon catheter. After reaching target position balloon is inflated and stent deployed and secured. Balloon catheter is deflated and removed. Stent implanted for 14-28-day time period (depending on healing process and therapeutic effect). The stent will be removed upon balloon catheter or using medical grasper, following cooling and self-crimping.
In control group patients will undergo post-FESS bilateral tampon placement into middle meatus as standard of care. Tampon will be removed at day 2-3 post surgery.
Patients in pilot study group (group 1) scheduled for 6 follow up visits at 1,2,3,4,6 and 12 weeks after implantation.

研究组 & 干预措施
pilot study group 1
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.
