Surgery was started following the standard CI procedures through posterior tympanotomy; however, due to bulging of the sigmoid sinus and a prolapsed tegmen, a canal wall-down mastoidectomy with an external auditory canal closure was performed.
Byway of a posterior tympanotomy, a cochleostomy in the scala tympani was performed with a diamond bur at low speed inferior and slightly anterior to the round window.
A suction-irrigation system was used; similar to the system used in humans, 4) posterior tympanotomy to obtain visual control of the round window niche and the promontory, 5) the round window membrane was opened with the beveled edge of a hypodermic needle, 6) insertion of the electrode array was made slowly through the round window.
