No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.
Summary
Randomized, controlled, blinded clinical trial with 40 patients randomized in a 1:1 ratio to either treatment (bilateral in-office placement of a drug-eluting implant in the ethmoid sinuses following ethmoidectomy) or control (post-op standard of care) group and followed for 6 months.
