Formaldehyde Fasciaform Tympanoplasty: A Reliable Technique for Closing Large Tympanic Membrane Perforations
Bibliographic record
Abstract
Formaldehyde fasciaform grafting tympanoplasty is a reliable method, in experienced hands, to close large tympanic membrane perforations. The technique involves using autogenous temporalis fascia shaped by formaldehyde cross-linking on a special fasciaform mold (Hear America, Palo Alto, CA). This study was undertaken with the objective of assessing if an otologist with less experience in using this technique could obtain comparable results. The results of the initial 23 patients treated in this manner by one surgeon between August 1996 and January 1998 are reviewed. Success was measured by the rate of closure of the tympanic membrane perforation and by functional closure of the air-bone gap. Favourable results were obtained, with complete closure of 86% of the perforations and closure of the air-bone gap to 20 dB or less in 90% of subjects when the ossicular chain was intact. The formaldehyde fasciaform tympanoplasty technique produces consistent, reliable, and reproducible results for large tympanic membrane perforations.

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.
