To analyze retrospectively the outcome of 6 cases of cochlear reimplantation to summarize its experience.The operation method of cochlear reimplantation was similar to routine cochlear implantation. A "H" incision for the muscle-periosteum was used to shorten the operation time.Of all the cases, the electrodes are successfully and totally inserted into the cochlea. The causes for revision are different. The electrode was found to be not in the proper situ of the cochlea after the first operation in one patient. The out part was ruptured because of trauma in another patient. The causes of the other four patients were unknown.The incision should not be too small. The control electrode should be put beneath the periosteum. The site used to fix up the out part need be burnished. Unabsorbable suture should do not be used. It is important to insert the new electrode quickly after drawing the old one out. The time to accommodate the new electrode often needs 3-4 weeks.
