Study Description
Brief Summary:
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.

Condition or disease Intervention/treatment
Cholesteatoma Other: MR Imaging

Detailed Description:
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.

Arms and Interventions

Arm Intervention/treatment
Analysis of the value of the imaging of distribution and the late sequence to differentiate the cholesteatoma of the fibrosis in the follow-up operating post at the child
Other: MR Imaging
MR imaging in the post operative follow-up of cholesteatoma in children

Outcome Measures

Primary Outcome Measures :
  1. 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 Outcome Measures :
  1. Only a surgical operation will confirm the diagnosis of cholesteatoma doing it again or residual. [ Time Frame: 24 months ]
  2. 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 ]
