Key Points

The aim is to establish normative linear measurements of inner ear structures using cone-beam CT.
Generated linear measurements from cone-beam CT images of inner ear structures.
Analyzed various parameters specific to the temporal bone.
Created reference values for assessing congenital hearing loss.
Established robust normative measurements for inner ear structures.
Potentially improved radiologic assessment of congenital hearing loss even in normal-appearing CT exams.

Abstract

This study provides robust CBCT-derived normative linear measurements of inner ear structures. These reference values may improve radiologic assessment of congenital hearing loss, particularly in patients with normal-appearing CT examinations.
