Hearing Outcomes in Functional Surgery for Middle Ear Malformations
Bibliographic record
Abstract
OBJECTIVES: To standardize the information for families of children having functional surgery for middle ear malformations, we describe the audiometric results of the subgroup of patients with the most favorable anatomic conditions: viable auditory canal, intact tympanic membrane, mobile stapes, and corresponding to a Jahrsdoerfer score of 8 or higher. STUDY DESIGN: Case series, tertiary referral center. METHODS: Charts of patients undergoing functional surgery for congenital middle ear malformations were reviewed for demographic data, preoperative Jahrsdoerfer score, ossicular chain status, type of ossiculoplasty, and audiometric data before and 6 months postsurgery. RESULTS: Eighteen consecutive interventions were performed on 13 patients (average age of 9 years, 8 girls and 5 boys) between 2004 and 2011. The ossiculoplasties performed were as follows: incus repositioning (4), double-layer tragal cartilage (5), intact native chain reconstruction (3), and partial ossicular prosthesis (6). Mean air bone gap (ABG) was 40.8 ± 12.4 dB preoperatively and 20.9 ± 12.9 dB postoperatively (p < 0.0001). Preoperative and postoperatively mean air conduction PTA thresholds were 49.9 ± 9.5 and 30.0 ± 14.1 dB, respectively (p < 0.0001). All ears operated on except one had air conduction improvement. There were no complications. CONCLUSION: Functional surgery for congenital middle ear malformations gives variable hearing outcomes. In this study, with the most favorable anatomic conditions, 12 ears (67%) of 18 had air conduction improvement below 30 dB.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
