Devices and Implants

Mesiarc provides audiology and speech language pathology services to children from birth to adulthood, including testing to determine the degree and type of hearing loss a child may have, fitting of devices to address any hearing loss (including hearing aids, bone conduction devices and cochlear implants), and assessment of the development of listening and communication skills, especially speech and oral language. We work closely with our children’s school and therapy personnel so that we may be, effectively, one team working toward the best possible communication outcomes for children with auditory disorders

Cochlear Implants

Multichannel cochlear implants have been approved by the Food and Drug Administration for use by children since 1990. Currently, three manufacturers make implants for sale in the US: Cochlear Corporation, Advanced Bionics, and MedEl Corporation.

Under FDA regulations, children may be candidates for cochlear implantation if they are at least 12 months of age and have severe to profound hearing loss with inadequate benefit from hearing aids to support development of auditory oral skills.

Regardless of manufacturer or model, all cochlear implants have the same basic features: a microphone picks up sound and converts it to an electrical signal which is transmitted to a speech processor worn either behind the ear or on the body. The processor encodes the signal in a manner that is specific to the particular implant, and the encoded signal is relayed to a transmitting coil held in place on the side of the head, usually by means of a magnet. The signal is sent across the skin via a radio frequency to the receiver which has been surgically implanted under the skin above and behind the ear. The receiver decodes the signal and relays the information to electrodes that have been placed in the cochlea. The electrodes stimulate structures connecting to the auditory nerve and thus the system provides improved access to sound;

In our program, surgery is performed under general anesthesia on an outpatient basis; children go into the hospital early in the morning and go home the same day. Three weeks later, the child comes back to the MESIARC Center for programming of the speech processor, and these programming or “mapping” sessions are repeated at frequent intervals until optimal levels are achieved, and then annually along with other progress assessments to monitor auditory development language skill levels.

Considering Cochlear Implantation

If you are not familiar with cochlear implants, you’ll find it helpful to spend some time visiting some schools attended by children with implants or spend time with families of children your child’s age or older who use cochlear implants.
Our cochlear implant center typically uses a multidisciplinary approach to determining candidacy, and your child will should evaluated by the surgeon, audiologist, speech language pathologist and psychologist who, as a team, will discuss with you your child’s candidacy for cochlear implantation in their program.

You may wish to ask the following:

What devices does the program use, what is their experience with the reliability of each device, and how compatible new external technologies have been to older internal devices, since you can expect your child to use the device you choose for many years.
How many pediatric implants has the surgeon performed and how many children has the audiologist mapped.
How is progress assessed and are speech perception testing and speech language evaluations performed regularly.
How does your center communicate with your child’s educators and therapists so that all your child’s providers can work effectively together.
Otology Master Class
From the Organizing desk

Dear friends,

MESIARC CME is here again. We have always strived to bring you the best in Otology, over the past 10 years, Our live surgery workshops, have focused on cutting edge surgery, detailed teaching, scientific deliberations of the highest order and top class video coverage from one of the most advanced otological theatre suites in the world this time, we are focusing on the enigma of budding otologists - cholesteatoma and Otosclerosis. Two very diverse conditions, but requiring surgical expertise of the highest order to deliver good results. The two-day surgical workshops will feature both myself and a luminary in Otology, Dr. Ashesh Bhumker from Thane, Mumbai and we would be demonstrating in detail the finer aspects of surgical techniques that can be adapted by a keen otologist to sustain good results over time.

We have lined up an array of diverse cases- and the techniques that we intend to demonstrate include minimal access stapedotomy, Laser stapes surgery, stapes surgery with stapes head amputation for tendon preservation, bone obliteration technique for cholesteatoma, a variety of grafting techniques, intact canal wall tympanoplasty for limited cholesteatoma and a series of revision surgeries.

Do send in your registrations early as we have to limit attendance to 70 seats. A smaller crowd is ideal for active discussions which is something so characteristic of MESIARC CME programs and we do not want to deviate from that agenda.

Yours truly,

Manoj MP  
Organizing chairman

Otology in Perspective Live Surgery 2015
From the Organizing desk

Mesiarc brings you a unique live surgical workshop- a demonstration of both endoscopic and microscopic otologic skills.

Otologic surgery is special for its intricate anatomy, extreme precision and attention to detail. Traditionally done with the operating microscope, and now in some centers across the world with the endoscope, the repetoire of the art is widening.

Confusion persists. Advocates of endoscopic work claim that the microscope is passe, and traditional surgeons laugh off the ability of the one handed

The truth lies somewhere in between; there are specific conditions that require either of both of the techniques. Dogmatism, they say, is the end of science.

Mesiarc brings you a unique live surgical workshop- a demonstration of both endoscopic and microscopic otologic skills.

MESIARC has always stood for dissipation of knowledge and the live surgical workshops are not pubilicity events, nor are they grandiose. We have just one agenda- to educate.

This workshop with a difference aims to demonstrate both endoscopic and microsopic skills in otologic surgery, while attempting to define which is more suitable for what. Do come and enjoy!

Yours truly,

Manoj MP  
Organizing chairman
