Endolymphatic Sac Surgery Versus Intratympanic Gentamicin for the Treatment of Intractable Ménière’s Disease
Bibliographic record
Abstract
OBJECTIVES: 1) To review a 10-year experience of endolymphatic sac surgery (ESS) and intratympanic gentamicin (ITG) for intractable Ménière's disease (MD), and 2) to compare preoperative and postoperative outcomes. DESIGN: Retrospective chart review and survey. SETTING: Tertiary care center. PATIENTS: Patients treated with ESS or ITG between 1997 and 2007 at London Health Sciences Centre were eligible for recruitment. INTERVENTIONS: ESS or ITG. MAIN OUTCOMES: 1) 1995 American Academy of Otolaryngology-Head and Neck Surgery hearing stage, vertigo class, and functional level; and 2) a 40-item validated quality-of-life questionnaire (MD Outcome Questionnaire). STATISTICAL ANALYSES: Chi-squared and t tests. RESULTS: Sixty-seven patients were recruited (n = 30 ESS; n = 37 ITG). Preoperatively, the ITG group had poorer hearing stage (p = 0.03). There were no differences between groups on preoperative functional level and QOL measures. Postoperatively, ESS patients reported more tinnitus (p = 0.003) and aural fullness (p = 0.01). There were no differences in posttreatment vertigo class. Secondary treatment was required for 27% of patients in the ESS compared with 3% in the ITG. Posttreatment hearing remained unchanged for the ITG and was overall decreased in the ESS group (p = 0.03). Participants in the ITG reported better postoperative functional levels (p = 0.02) and higher global (p = 0.04), social (p = 0.001), and overall QOL scores (p = 0.03). CONCLUSION: ITG, compared with ESS, reveals better posttreatment functional levels, and superior global, social, and overall QOL scores. Although no statistical difference in vertigo class, a clinical difference is observed.

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.
