Abstract

Purpose: To investigate the influence of arcuate eminence's distance to temporal bone outer table (AE-OT) on surgical outcomes following the middle fossa repair of superior canal dehiscence (SCD).

Methods: We conducted a cohort study of consecutive repairs at a center between 2011 and 2022. AE-OT was measured on temporal bone CT imaging. Surgical outcomes were assessed with established metrics including Symptom Resolution Score (SRS), rate of Overall Symptom Improvement (OSI), and change in low-frequency air-bone gap (ΔLF-ABG) from pre- to post-surgery. Multivariable regression models assessing surgical outcomes were constructed with AE-OT as the primary predictor. Models adjusted for patient demographics, medical and surgical history, and follow-up duration.

Results: A total of 402 repairs were included. Mean AE-OT was 27.1 mm (SD 2.1, range 20.8-33.9). Every mm increase in AE-OT was independently associated with a 14% reduction in odds of OSI (aOR 0.86, 95% C.I. [0.75, 0.98]) and a 4-point decrease in SRS (adj. β - 4.0 [- 6.9, - 1.1]) among frank dehiscences. AE-OT was also not associated with operative duration and ΔLF-ABG among both frank dehiscences and near dehiscences.

Conclusions: Longer AE-OT predicted poorer symptomatic response but similar operative duration and audiometric improvement among frank SCD cases.
