Nasopharyngoscopy in palatopharyngeal prosthetic rehabilitation: A preliminary report.
Bibliographic record
Abstract
PURPOSE: Prosthetic rehabilitation of speech disorders related to palatopharyngeal dysfunction is accomplished through separation of the oral and nasal cavities. The ability to achieve this separation is challenged when the disorder or defect involves the soft palate. Prosthetic rehabilitation of soft palate disorders and defects has traditionally relied on functional contouring of a prosthesis using functionally adapted impression materials. However, there are limitations to this process, particularly in its inability to visualize function as it relates to the prosthesis in a 3-dimensional space. The aim of this study was to address this limitation by describing outcomes related to the use of nasopharyngoscopy (NPS) for visualization of the velopharyngeal port during assessment and treatment of palatopharyngeal dysfunction. MATERIALS AND METHODS: A retrospective analysis of speech data was conducted for 5 patients who were assessed before treatment, after prosthetic intervention using conventional functional impression techniques, and after prosthetic intervention using NPS. Nasalance and velopharyngeal orifice area outcome measurements were collected for each patient at clinically predetermined intervals. Perceptual assessment of speech samples was performed as well. RESULTS: Improvements in speech function were observed for all patients after treatment with a prosthesis designed via a conventional functional impression technique; however, no patient showed normal values for nasalance or velopharyngeal orifice area. With the use of NPS to adjust the wax impression-derived prosthesis, both nasalance and velopharyngeal orifice area measurements for all patients were within normal limits. Similarly, perceptual judgment of speech found that normal resonance balance was obtained after use of NPS. CONCLUSION: The addition of NPS into prosthetic treatment for palatopharyngeal disorders shows promise for improved speech results.

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.
