Abstract
Dear Editor, Classical hemifacial spasm (HFS) has been attributed to an atraumatic pulsatile vascular compression of the facial nerve leading to hyperactivity within the central components of the nerve, alleviated via mobilization of the culprit vessel [1]. In a small subset of patients the cause may be attributed to lesions involving the facial nerve, most commonly benign cerebellopontine angle (CPA) tumors [2,3]. In such secondary HFS the clinical manifestation is usually a tonic facial contraction rather than the intermittent twitching characteristic of common HFS [4,5]. There may, however, also be rare patients with a common presentation of HFS but with an associated CPA tumor [6,7]; the role of neurovascular compression (NVC) in these cases is uncertain. We present 2 cases of secondary HFS, both related to benign CPA tumors.

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
