To avoid being asked to do an overtime and to reserve my energy as well considering I still have 7 days left to work, I asked the HNOD if I could have a 5-1 shift instead and fortunately she granted it to me.
Anyways, my case for today is Cochlear Implant Surgery. It is not a frequent surgery done in our hospital so I'm really lucky to assist in this kind of surgery. Anyways, here's a closer look in this surgery.
COCHLEAR IMPLANT SURGERY
Definition: A cochlear implant is a small, complex electronic device that can help to provide a sense of sound to a person who is profoundly deaf or severely hard-of-hearing. The implant consists of an external portion that sits behind the ear and a second portion that is surgically placed under the skin.
Procedure:
The actual surgical procedure, which takes 2 to 4 hours and uses general anesthesia, involves securing the implant package under the skin and inside the skull, and then threading the wires containing the electrodes into the spirals of the cochlea.
To secure the implant, the surgeon first drills a 3- to 4-millimeter bed in the temporal bone (the skull bone that contains part of the ear canal, the middle ear, and the inner ear). Next the surgeon opens up the mastoid bone behind the ear to allow access to the middle ear. Then, a small hole is drilled in the cochlea and the wires containing the electrodes are inserted. The implant package is then secured and the incision is closed.
