Abstract
OBJECTIVE: To compare NasoPore (Stryker Canada, Hamilton, ON, Canada) and a traditional middle meatal spacer (MMS) composed of Merocel ((Medtronic Xomed, Mississauga, ON, Canada) placed in a vinyl glove finger in functional endoscopic sinus surgery (FESS) with regard to postoperative bleeding, wound healing, and patient comfort. DESIGN: A prospective, double-blind, randomized trial of 30 consecutive adults (age > 16 years) with chronic or recurrent acute rhinosinusitis undergoing bilateral FESS, excluding patients with significant difference in their sinus disease bilaterally using preoperative computed tomographic scan assessment (Lund-McKay scores > 2). SETTING: Tertiary hospital, Vancouver, British Columbia. METHODS: Preoperatively, all patients were randomized and blinded to receive NasoPore (Stryker Canada) on one side and Merocel on the other. Patients completed a questionnaire during their first postoperative week relating to their subjective assessment of pain, pressure, nasal blockage, swelling, and bleeding. Patients were evaluated 1 week postoperatively for packing removal and debridement, and associated discomfort and bleeding with the removal, as well as overall preference for either pack. A clinician blinded to the randomization process objectively assessed the healing status of the nasal cavities at 4 and 12 weeks postoperatively. MAIN OUTCOME MEASURES: Patient satisfaction, bleeding, and wound healing postoperatively. RESULTS: Thirty patients were enrolled. There was no significant difference between the Lund-Mackay scores in both groups preoperatively (p = .80). Postoperatively, there was no significant difference between both groups with regard to patients' pain, pressure, blockage, swelling, bleeding, or discomfort on packing removal (p > .05). There was no statistical difference in the amount of bleeding associated with packing removal (p = .32). Mucosal grading at 4 weeks was significantly better for the traditional MMS (p = .03), but this difference disappeared at the 12-week visit (p = 1.00). CONCLUSIONS: The absorbable pack did not significantly reduce the risk of bleeding or patient discomfort compared with a traditional nonabsorbable MMS and was associated with significantly slower mucosal healing initially, an effect that disappeared after 3 months postoperatively. There was no significant patient preference for either pack.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
