Facial nerve outcome with a Peroperative stimulation threshold under 0.05 mA
Bibliographic record
Abstract
OBJECTIVES/HYPOTHESIS: To evaluate the facial nerve outcome postoperatively of schwannoma vestibular surgery with a stimulation threshold (ST) lower than 0.05 mA. STUDY DESIGN: Retrospective chart review. METHODS: A total of 106 patients had undergone schwannoma vestibular surgery between 2002 and 2008 in a tertiary center. The ST near the brainstem was obtained after the tumor removal. Facial nerve function was evaluated according to the House-Brackmann (HB) scale immediately postoperatively and at 1 year. The results were compared among the different STs used: <0.05 mA, 0.05 mA, and >0.05 mA. RESULTS: There were 50 patients who had an ST <0.05 mA, 45 patients who had an ST of 0.05 mA, and 11 patients who had a ST >0.05 mA. Immediately postoperatively, for all of these groups we had a preservation of facial nerve function (HB I-II) in 94%, 80%, and 36% of patients, respectively (P < .0001). At 1 year in the same groups the preservation of the facial nerve function was 100%, 93%, and 82% of patients, respectively (P < .01). CONCLUSIONS: A proximal ST of <0.05 mA is a better predictor of facial nerve function immediately postoperatively.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
