Only PROPEL Contour combines mechanical spacing and localized drug delivery to the maxillary sinus, thereby maintaining sinus patency1

Watch Dr. McKinney discuss the case of a 59-year-old woman with CRS and nasal polyposis refractory to medical management and prior MAXILLARY sinus surgery


  • Developed bacterial infection postsurgery

  • Infection was treated with antibiotics and saline rinses

  • CRS symptoms continued

  • Endoscopy reveals thick mucus and residual scar tissue

  • Next steps: revision maxillary mega-antrostomy with PROPEL Contour

CRS, chronic rhinosinusitis.

PROPEL Contour is an hourglass-shaped implant, 8 mm in nominal length, and indicated for the frontal and or maxillary sinus ostia1

Surgery + PROPEL Contour provides benefits following maxillary sinus surgery1,2

  • PROPEL Contour delivery success rate (primary endpoint) in maxillary sinuses was 95.2% (N=15)

  • 100% maxillary sinus ostial patency (secondary endpoint) was achieved at Day 30 (N=15)

  • Reduction in inflammation was observed at Day 30

Study Design: EXCEED was a 15-patient, prospective, single-arm, open-label feasibility trial. Patients were implanted with PROPEL Contour into the maxillary sinus ostia following sinus surgery with traditional instrumentation, balloon dilation, or a hybrid of both.1,3

For significant improvements to patient outcomes following sinus surgery, add PROPEL Contour to your battle for the maxillary sinus*
