Abstract
OBJECTIVES: (1) To assess the long-term impact of thyroid ala cartilage laryngotracheal reconstruction (TAC-LTR) on health-related quality of life (QOL) in infants using 4 validated instruments: Health Utility Index version 3 (HUI3), Pediatric Voice-Related QOL (PVRQOL), Impact on Family Questionnaire, and a visual analog scale and (2) to perform acoustic and perceptual voice assessments to evaluate longterm voice quality outcomes. STUDY DESIGN: Prospective study. SETTING: Tertiary academic pediatric hospital. SUBJECTS: Eligible children who received TAC-LTR before the age of 24 months between 1995 and 2007. METHODS: Interviews with parents and children using 4 validated instruments, voice analyses, and endoscopic evaluation were performed. RESULTS: Twelve patients (7 male, 5 female, median age 10 years) were enrolled over a 6-month period. The mean age at LTR was 5 months (range, 1-20 months), and the mean study followup period was 9 years (range, 2-14 years). The average speech HUI3, PVRQOL, and Impact on Family scores were 0.83 (95% confidence interval = 0.74, 0.92), 0.93 (interquartile range [IQR] = 0.81, 1.00), and 0.65 (IQR = 0.54, 0.92), respectively. All acoustic scores were either normal or mildly abnormal for the variables jitter, shimmer, noise-to-harmonic ratio, peak amplitude variation, and fundamental frequency. The Consensus Auditory-Perceptual Evaluation of Voice overall severity score was in the normal to mildly abnormal range for 8 of 9 patients. CONCLUSION: This is the first study to explore and quantify longterm QOL and voice quality in children following LTR with thyroid ala graft at a very young age. Most patients had very good functional voice outcome as evidenced by the HUI3 and PVRQOL scores. This was corroborated by acoustic and perceptual voice assessments.

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
