Functional Disorders of the Larynx: Muscle Tension Dysphonia, Paradoxical Vocal Cord Dysfunction, and Globus Pharyngeus
Bibliographic record
Abstract
Functional disorders of the larynx can present in a diverse manner with symptoms such as dysphonia, dyspnea, and dysphagia. Muscle tension dysphonia (MTD) may cause disrupted phonation due to overactive laryngeal musculature. MTD is diagnosed by a thorough clinical history and laryngoscopic visualization of the vocal cords and supra-glottic region. Vocal hygiene and voice therapy are the foundations of MTD treatment with concomitant medical therapy when indicated. Paradoxical vocal cord dysfunction (PVCD) can cause shortness of breath due to inappropriate vocal cord adduction during respiration. Laryngoscopic evaluation is the gold standard in the diagnosis of PVCD and remains an important investigation to differentiate PVCD from other respiratory conditions. Patient reassurance during an acute event of PVCD is most often indicated, whereas speech therapy is the principal treatment for the prevention of further episodes. Globus pharyngeus may present as the sensation of a lump in the throat, although the etiology of this functional disorder remains unclear. The diagnosis of globus pharyngeus requires the exclusion of alternative diagnoses such as gastroesophageal reflux disease and major esophageal motor disorders. Globus pharyngeus is a benign disorder that can be treated with careful reassurance, a trial of gastric acid suppression, or neuromodulator medications. Altogether, functional disorders of the larynx require careful attention from clinicians. When such disorders are appropriately diagnosed and treated, the quality of life of patients can greatly improve.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
