Magnetic Resonance (MR) Imaging in the Post Operative Follow-up of Cholesteatoma in Children

Assistance Publique Hopitaux De Marseille37 enrolled

Overview

Classical imaging techniques are inaccurate to detect residual cholesteatoma. The aim of our study is to evaluate the value of diffusion-weighted MR imaging and delayed contrast enhanced T1 weighted spin-echo sequences in the detection of residual cholesteatoma in children, in a large serie of surgically verified cases.

Classical imaging techniques are inaccurate to detect residual cholesteatoma. Thin-section CT detects that the postoperative cavity is filled with a soft tissue mass. Classical MR imaging (T2 and T1 weighted spin-echo sequences) can not provide additionnal information about the nature of this filling : cholesteatoma, granulation or fibrous tissue.

Outcomes

Primary Outcomes

Technical characteristics of the examination MRIs represented by the sensibility and the specificity of the test, with regard to the results stemming from the surgical operation

Time frame: 24 months

Secondary Outcomes

Only a surgical operation will confirm the diagnosis of cholesteatoma doing it again or residual.

Time frame: 24 months

It is necessary to test the following diagnostic method: the analysis of the morphological sequences in T1 and in T2 will allow to appreciate the existence or not of a filling of the cavity tympanique or the mastoïde and to clarify its localization.

Time frame: 24 months
