Evaluation of cochlear implant electrode position after a modified round window insertion

A study estimated the postoperative cochlear implant electrode position using a modified round window approach to insert primarily into the scala tympani.

"In 78 (95.1%) patients, the array could be located in the scala tympani. In four cases, the position of the electrode was changed intracochlearly from the scala tympani to the scala vestibuli. In three additional cases, the scala vestibuli was inserted intentionally because the tympanic scale was found to be obstructed intraoperatively due to ossification. There were no significant differences between the intraoperative positioning and postoperative localization of the electrode arrays of the two manufacturers."
