Association of Tympanostomy Tubes With Future Risk of Advanced Ear Surgery—A Population Study
Bibliographic record
Abstract
OBJECTIVE: To investigate future surgery for chronic ear disease in children who underwent tympanostomy tube (TT) placement, compared with non-surgically treated patients and healthy controls. STUDY DESIGN: Retrospective population-based cohort study. SETTING: All hospitals in the Canadian province of Ontario. PATIENTS/INTERVENTION: Of children aged 18 years and younger, three cohorts were constructed: 1) TT: patients who had undergone at least one TT procedure (n = 193,880), 2) No-TT: patients with recurrent physician visits for middle ear concerns who did not undergo TT (n = 203,283), and 3) Control: an age-sex matched control group who had not had TT or physician visits for recurrent middle ear concerns (n = 961,168). MAIN OUTCOME MEASURES: Risk, and odds ratios (ORs) of surgery for chronic ear disease. RESULTS: The TT cohort had a higher risk of tympanoplasty (OR 9.50 versus No-TT, p < 0.001; OR 207.90 versus Control, p < 0.001), ossiculoplasty (OR 3.22 versus No-TT, p < 0.001; OR 84.13 versus Control, p < 0.001), atticotomy (OR 4.41 versus No-TT, p < 0.001; OR 44.78 versus Control, p < 0.001), and mastoidectomy (OR 3.22 versus No-TT, p < 0.001; OR 89.12 versus control, p < 0.001). CONCLUSION: This study describes the population risk of subsequent ear surgeries in TT patients. These TT patients have a significantly higher risk of surgery for chronic ear disease versus those patients with recurrent middle ear disease that did not undergo TT, and age-sex matched controls.

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.
