implanted into the temporal bone (the bone surrounding the ear). It consists of a receiver-stimulator, which accepts, decodes, and then transmits an electrical signal to the brain.
The second part of the cochlear implant is an external device. This consists of a microphone/receiver, a speech processor, and an antenna. This portion of the implant receives the sound, converts the sounds into an electrical signal, and transmits it to the internal portion of the cochlear implant.
Cochlear implants allow deaf people to receive and process sounds and speech. To a certain degree, they are devices that allow deaf people to "hear." However, it is important to understand that these devices do not re-establish normal hearing - they are tools that allow sound and speech input to be processed and transmitted to the brain.
The criteria used to select appropriate candidates for cochlear implants are changing over time - as both the technology changes, and our understanding of the brain's auditory (hearing) pathways improves.
Both children and adults can be candidates for implantation. They may have been born deaf or become deaf after learning to speak. Children as young as 1 year old are now candidates for this surgery. Although adult and pediatric criteria are slightly different, they are based on similar guidelines.
Surgery for inserting a cochlear implant is performed with the patient fully asleep. An incision is made behind the ear. Then a microscope and a bone drill are used to open the bone, allowing the insertion of the internal part of the implant.
The electrode array is then passed into the cochlea (inner ear). The receiver is placed into a "well" created behind the ear to help keep it in place, and to make sure it is close enough to the skin to allow transmission of electrical information from the external portion of the device.
After surgery, there will be stitches behind the ear, and you may be able to feel the receiver in its "well" behind the ear. The external portion of the device will be placed about 3-4 weeks after surgery, to give the incision time to heal.

Vocal Box and Larynx - Voice disorders, tumors etc.

Vocal folds vibrate so fast during sound production that this vibration is impossible to see with the naked eye, similar to the wings of a hummingbird.
Stroboscopy is a special method used to visualize vocal fold vibration. It uses a synchronized, flashing light passed through a flexible or rigid telescope to visualize vocal fold vibration. The flashes of light from the stroboscope are synchronized to the vocal fold vibration at a slightly slower speed, allowing the examiner to observe vocal fold vibration during sound production in what appears to be slow motion. This "slow motion picture" is an illusion, as the speed of actual vocal fold vibration is not changed by stroboscopy. This special viewing allows the voice care team to evaluate each vocal fold's vibration properties during the different phases of the vocal fold's vibration cycle.
Phonosurgery is the term of various surgical procedures that maintain, restore, or enhance the human voice. Phonosurgery includes phonomicrosurgery (microsurgery of the vocal folds done through an endoscope), laryngoplastic phonosurgery (open-neck surgery that restructures the cartilaginous framework of the larynx and the soft tissues), laryngeal injection (injection into the larynx of medications as well as synthetic and organic biologic substances), and the re-innervation (restoration of the nerve supply) of the larynx.

Laryngectomy refers to the surgical removal of the voice box, or larynx, in people whose larynx has been affected by cancerous tumor or any other trauma. Since a laryngectomy is a major surgery that affects the patient's ability to speak, the procedure also involves extensive rehabilitation program for the patient after surgery. ENT Departments in Israel offer the best treatment for neck and throat problems, including treatment for tumors and accidents that have damaged the larynx. However, if treatments like radiation and chemotherapy, as well as minor surgery, fail, then a complete laryngectomy is the only option. Israeli hospitals offer the best in terms of post operative care and rehabilitation. After Laryngectomy, patients may opt for the excellent speech therapy sessions available at the hospital plus thorough evaluation and treatment of disorders arising from conditions like hearing disorders and Laryngectomy.
