Cartilage Recycling in Rhinoplasty: Polydioxanone Foil as an Absorbable Biomechanical Scaffold
Bibliographic record
Abstract
BACKGROUND: Primary and secondary rhinoplasty often requires multiple cartilage grafts. Polydioxanone foil may be used as a temporary biomechanical scaffold on which routinely discarded cartilage fragments can be assembled to make maximal use of harvested material. METHODS: The authors performed an outcome analysis of 58 primary and secondary rhinoplasties in which polydioxanone foil was used in combination with autologous cartilage for aesthetic and valvular reconstruction of the nose. Graft performance, complications, and technical points are reported. RESULTS: The temporary scaffold (polydioxanone foil) was used most often to construct columellar struts, septal extension grafts, and alar battens. Other uses included revision septoplasty and upper lateral replacement grafts. Two minor complications occurred: one infection and one partial extrusion. The long-term stability of the nose following this technique was found to be satisfactory (mean follow-up, 18 months), for both structural and aesthetic purposes. CONCLUSIONS: This technique is both simple and effective. By making maximal use of otherwise discarded cartilage fragments, it protects other graft harvest sites and decreases the incidence of the "graft-depleted" patient.

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.
