This video shows a transotic approach for a cochlear schwannoma in a 59-year-old female who presented with sudden sensorineural hearing loss in her left three years prior. She was found to have subsequent growth of her tumor on imaging and elected to undergo surgery. The transotic approach is a valuable approach within the armamentarium of a skull base team and differs from the transcochlear approach in the handling of the facial nerve. Techniques for ear canal overclosure, eustachian tube packing and mastoid obliteration are also highlighted.
