Abstract
OBJECTIVES: To determine the feasibility of identification of the external branch of the superior laryngeal nerve (EBSLN) during routine thyroidectomy and to describe the EBSLN position according to the Cernea classification system. DESIGN: Prospective case series. SETTING: Academic tertiary care center. PATIENTS: One hundred twelve consecutive patients undergoing hemithyroidectomy or total thyroidectomy by the senior author between August 15 and December 31, 2007. INTERVENTIONS: None. MAIN OUTCOME MEASURE: Proportion of EBSLNs identified. Secondary outcome measures included EBSLN position according to Cernea classification and correlation with patient and gland characteristics. RESULTS: Three of 178 EBSLNs (1.7%) could not be identified using the routine technique. The EBSLN was found in the highest-risk position (Cernea type 2b, crossing the superior vascular pedicle below the upper border of the gland) in 48.3% of cases, and in the lowest-risk position (Cernea type 1, crossing more than 1 cm above the upper border) in 7.3%. Specimens larger in weight and in dimension were correlated with type 2b nerves. CONCLUSIONS: The EBSLN can be routinely identified during thyroidectomy. Moreover, many EBSLNs are in position to be at high risk of injury during ligation of the superior vascular pedicle.

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
