Intracochlear Imaging Using IVUS and OFDI: A Cadaveric Feasibility Study.

ABSTRACT:

Objective

This study evaluates the feasibility of optical frequency domain imaging (OFDI) and intravascular ultrasound (IVUS) for intracochlear imaging in human cadaveric specimens. We compare their resolution, depth penetration, and ability to identify key cochlear structures and pathological conditions.

Methods

Human cadaveric temporal bones were prepared, and OFDI and IVUS probes were inserted through the round window into the scala tympani. OFDI imaging was performed using the LUNAWAVE system (Terumo, Tokyo, Japan), while IVUS imaging was conducted using the VISICUBE system (Terumo, Tokyo, Japan) with 60 and 40 MHz probes. The probe tips were trimmed to optimize insertion and imaging. Imaging results were compared with histological sections.
