Brief Summary
Adult patients referred to the ENT surgery department of the Hospices Civils de Lyon with cholesteatoma that had never been operated on. All patients will benefit from surgical management for cholesteatoma initially in the operating room under general anesthesia. The surgical technique (closed technique) is the reference technique for the management of cholesteatoma in adults. It involves a cartilaginous removal to reconstruct the attical region. Then a filling material is used to fill the mastoid (GlassBONE™ or Bonalive™), and above all to stabilize the cartilaginous fragment to prevent a recurrence.

mastoid filling
A patient will be considered as a responder if the proportion of mastoid filling at 6 months is strictly greater than 70% compared to the reference measurement
6 month
Study Arms (1)
patient with cholesteatoma who has never been operated on
All patients will benefit from surgical management for a first stage cholesteatoma in the operating room under general anesthesia. The surgical technique (closed technique) is the reference technique for the management of cholesteatoma in adults. It involves a cartilaginous removal to reconstruct the attical region. Then a filling material is used to fill the mastoid (GlassBONE™ or Bonalive™), and above all to stabilize the cartilaginous fragment to prevent a recurrence. The mastoid filler used is left to the discretion and habits of the surgeon.
