Brief Summary:

Gene therapy is a promising strategy to treat hearing loss and vestibular disorders, and Associated adenovirus (AAV) is shown as a good viral vector for inner ear therapy in animal models.

This study aims to study in vitro viral transduction of AAV in human inner ear cells, collected during non-conservative surgeries for vestibular schwannoma.

Group/Cohort Intervention/treatment
AAV viral transduction
Collection of inner ear cells during a non-conservative surgical approach (translabyrinthine or transotic).
 Other: Peroperative collect of inner ear cells

After obtaining an informed consent during the preoperative medical visit, and if a non-conservative approach (translabyrinthine or transotic) is decided, the collect of inner ear cells will be performed during surgical approach.

The sample will be collect in a sterile tube, and carried to the laboratory were it will be placed bon cell culture.

Primary Outcome Measures :
  1. AAV transduction in inner ear cells [ Time Frame: 10 days ]
    The transduction will be measured with immunostaining techniques
