Surgery

Surgery usually takes between 2 and 4 hours. The risks of cochlear implant surgery are small and are similar to other ear surgeries.

	A general anesthetic is usually given.
	The hair is shaved in the area where the incision is to be made.
	An incision is made.
	A “bed” is made in the mastoid bone behind the ear. The implant will be placed in this bed.
	An opening is made into the cochlea.
	The electrode array is inserted into the cochlea.
	The electrode array and the implant are secured in place.
	The electrode function is tested before the incision is closed.
	There is usually some discomfort after surgery. Pain medication can be given if necessary. Patients are usually up and about the next day. The hospital stay depends upon local practice and can be as short as one day.
