BAHA / Ponto Bone Conduction Devices

Children with atresia (where ear canals do not develop), and other conditions that prohibit the use of conventional hearing aids and ear molds, can benefit from devices placed on the mastoid bone behind the ear. This type of device causes vibration of the inner ear, stimulating the hair cells of the cochlea without going through the middle ear as hearing aids do.

MESIARC provides bone-anchored hearing aids which are surgically implanted abutment to transmit sound by direct conduction through bone to the inner ear, bypassing the external auditory canal and middle ear. A titanium prosthesis is surgically embedded into the skull with a small abutment exposed outside the skin. A sound processor sits on this abutment and transmits sound vibrations to the titanium implant. The implant vibrates the skull and inner ear, which stimulate the nerve fibers of the inner ear, allowing hearing.

The titanium fixture bonds with the surrounding bone in a process called osseointegration. The sound processor can be attached and used once osseointegration is complete, usually two to six months after implantation.

Both Cochlear and Oticon Medical's Baha in collaboration with MESIARC offer bone conduction hearing solutions via a bone-anchored sound processor that convert incoming sound into vibrations. Cochlear Baha utilises a snap-lock coupling which allows them to clip onto the implanted abutment, The Oticon Ponto uses a spring based coupling. The sound processor units run on small circular batteries which last approx 6 to 14 days. The coupling is designed to detach upon impact as a safety feature to prevent damage to the bone or surrounding tissues.

 
 
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,

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
