Cholesteatoma Clinical Trial
Official title:
Short- and Medium-term Evaluation of Mastoid Filling Using Bioactive Glass"
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.
Patients are operated on as an outpatient and receive a phone call the next morning to look for an initial complication. The patients will be reviewed in consultation at D8, D45, 3 months, 6 months and at 18 months with clinical examination (otoscopy) and audiometry at each consultation. The consultation on D8 is used for removal of the expandable cotton put in place in the external auditory canal (CAE) during surgery to guide healing, control post-auricular healing and look for signs of complication during the examination. A cone beam (CBCT) is performed during the consultation on D45 to confirm the correct position of the ossiculoplasty and check the persistence of the initial filling. The proportion of filled mastoid at D45 will serve as a reference to then be compared to the CT scan at 6 months and at 18 months. During surgery, and at the consultation at 6 months and 18 months, patients will also have to complete a quality of life questionnaire (Chronic Ear Survey French version; in the Appendix). ;
