Arm | Intervention/treatment |
---|---|
No Intervention: Control
Subjects within the control arm will undergo the Draf III/Endoscopic Modified Lothrop procedure to address their sinus disease. At the end of the procedure, no Cook Biodesign Porcine intestinal submucosal graft will be used to cover the operative site. Light nasal packing will be placed in the nasal cavity for hemostasis. No placebo will be utilized.

|
Experimental: Cook Biodesign
Subjects within the experimental group will undergo the Draf III/Endoscopic Modified Lothrop procedure to address their sinus disease. At the end of the procedure, a small piece of Cook Biodesign porcine intestinal submucosal xenograft will be used to cover the exposed bone of the operative site along the frontal beak. It will be bolstered with light nasal packing to keep the graft in place during healing.

Device: Porcine Intestinal submucosal xenograft
Cook Biodesign ENT repair graft will be used in the experimental group to cover exposed bone in the sinonasal cavity as a result of the Draf III/endoscopic modified lothrop procedure.
