Abstract
BACKGROUND
The fusion of computed tomography images with non-echo planner diffusion-weighted magnetic resonance images may overcome the limitations of each individual modality.
OBJECTIVES
This study aimed to assess the ability of the 'fusion' technique to predict the location of middle ear cholesteatoma by evaluating Its impact on preoperative surgical planning and postoperative results.
METHODOLOGY
Eighty-three adults with cholesteatoma underwent preoperative CT scans and non-EPI-DW-MRI with or without the 'fusion' technique. We evaluated cholesteatoma localization in both groups, selecting the most appropriate surgical technique, and correlating it with the intraoperative findings. Both groups were compared in terms of residual/recurrent cholesteatoma at one, six and twelve months after surgery.
RESULTS
The 'fusion' technique's sensitivity, specificity, and accuracy in predicting the location of cholesteatoma were 97.5. 97.4, and 97.5%, respectively, versus 97.59, 57.69, and 73.21% of CT alone. There was a total operators agreement after the evaluation of the 'fusion' images with the adopted surgical technique. A statistically significant decrease in residual and recurrence cholesteatoma rates was found in group A.
CONCLUSIONS
The 'fusion' technique provides the surgeon with the precise cholesteatoma location, guiding him in making the correct surgical decision, contributing to the decrease in postoperative residual and recurrence rates.
