MRI-DWI detection of residual cholesteatoma: moving toward an optimum follow-up scheme.

ABSTRACT:

Purpose

To analyse diagnostic accuracy of MRI-DWI in detecting residual disease after cholesteatoma surgery and propose an optimum follow-up (FU) scheme.

Method

A retrospective chart review of patients who had cholesteatoma surgery in a tertiary referral centre. 3.0 T non-echo planar diffusion weighted imaging was performed as part of routine FU or indicated on the basis of clinical suspicion of disease. Imaging outcome was verified per-operatively during a second-look procedure or ossicular chain reconstruction. Diagnostic parameters were calculated and stratified by FU length.

Results

For the FU of 664 cholesteatoma surgeries, 1208 MRI-DWI were obtained and 235 second-look procedures were performed. Most MRI-DWI were obtained within 1.5 yrs of surgery. In this perio
