Abstract
OBJECTIVE: While bone-anchored hearing aids (BAHAs) are currently indicated for rehabilitation in children older than 5 years with bilateral maximal conductive hearing loss, our objective was to capitalize on potentially important stages of auditory and speech-language development by providing BAHAs to children younger than 5 years. DESIGN: A retrospective review of surgical data of children receiving BAHA implants over a 10-year period. SETTING: The Hospital for Sick Children, Toronto, Ontario. PATIENTS: Twenty children 5 years or younger (mean +/- SD age, 3.21 +/- 1.65 years) served as the study group, while 20 older children (mean +/- SD age, 7.63 +/- 1.55 years) served as the comparison group. INTERVENTIONS: All patients received BAHA implants. Children with cortical bone thickness less than 2.5 mm underwent a 2-stage procedure; children with cortical bone thickness greater than 4 mm underwent a single-stage procedure. MAIN OUTCOME MEASURES: Traumatic and skin revision complication rates and implantation interstage intervals were compared between groups. RESULTS: The mean +/- SD interstage interval was 7.72 +/- 3.81 months for the younger children, which was significantly longer than for the older children (4.41 +/- 2.51 months) (P<.003). Two traumatic fixture losses occurred in the younger children, while 4 occurred in the older children. Skin site revision was required in 3 younger children. All children are currently wearing their BAHAs. CONCLUSION: Two-stage BAHA implantation with a prolonged interval between stages yields surgical success in younger children comparable to that routinely observed in older children.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
