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.

Outcome Measures

Primary Outcomes (1)

  • AAV transduction in inner ear cells

    The transduction will be measured with immunostaining techniques

    10 days

Study Arms (1)

AAV viral transduction

Collection of inner ear cells during a non-conservative surgical approach (translabyrinthine or transotic).

Other: Peroperative collect of inner ear cells

Interventions

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.
