Abstract
OBJECTIVE: To determine the prevalence of laryngomalacia among children presenting with symptoms of sleep-disordered breathing (SDB). METHOD: A retrospective observational study was conducted at a tertiary care paediatric hospital. All children presenting with SDB during a 55-month period were investigated using sleep nasopharyngoscopy (SNP). Patients who had laryngomalacia were identified. Patients who did not present primarily with SDB, or were not examined with SNP were excluded. Data for analysis was collected from a prospectively kept surgical database and medical records. This included patients' demographics, symptoms (including symptoms in infancy), diagnoses, SNP findings, overnight pulse oximetry findings, and treatment. RESULTS: We identified 358 patients with documented primary diagnosis of SDB and who had undergone SNP. Fourteen of these also had a documented diagnosis of laryngomalacia, giving a prevalence rate of 3.9%. Three children were syndromic, and one had cerebral palsy in addition to SDB and laryngomalacia. Three children were obese, and three children had gastroesophageal reflux disease. Seven cases (50%) had symptoms of snoring and/or swallowing dysfunction and/or stridor in infancy. Twelve patients had adenotonsillar surgery. In eight cases symptoms resolved completely with adenotonsillar surgery only. In total, six patients had a supraglottoplasty. There were three failures to supraglottoplasty. CONCLUSION: The prevalence of laryngomalacia within children presenting with SDB is 3.9%. Our findings support full evaluation of the airway to identify the site of pathology mediating SDB symptoms.

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
