Cortical mastoidectomy with restoration of separation between the sigmoid sinus and middle ear is also considered medically necessary for tinnitus from a bony defect when a sigmoid sinus dehiscence is documented on temporal bone imaging. Tinnitus instruments such as maskers and hearing aids are considered experimental, investigational, or unproven, along with a list of other tinnitus interventions that includes acupuncture, cochlear implants, TENS, transcranial magnetic stimulation and vagus nerve stimulation.
