Magnetic resonance imaging of the middle ear has an increasing place in the therapeutic strategy in otology and especially for cholesteatoma. It is currently performed for complicated cholesteatomas and as part of the follow-up of operated patients to detect a recurrence or a cholesteatoma residue (alternative of choice to "second look" surgery). Some people take CT and MRI fusion to improve the localization of cholesteatoma. Many studies have investigated the diagnostic capabilities of MRI but very few have demonstrate their reliability in location diagnosis. The aim of the study was to propose a topographic reading method of the MRI of the middle ear and to evaluate the performances in the localization of the cholesteatoma in order to adapt the surgical management

Cholesteatoma of the middle ear (H71)
Diagnosis of macroscopic and / or pathological cholesteatoma.
Preoperative diagnosis of cholesteatoma on MRI of the middle ear performed in less than 6 months by the same radiologist (Pr Francis Veillon).
Subject (or the holders of parental authority in the case of minors) having agreed to the use of medical data for the purpose of this research.
Cholesteatoma is a very common disease in the pediatric population, with important functional issues, whose treatment is surgical. That's why our study includes minor subjects.
Criteria of non-inclusion
Refusal of the patient to participate in the study
Absence of data concerning the diagnosis and / or localization of cholesteatoma on the operative record
