Ear diseases can be extremely dangerous if left untreated. At BOSH we follow state of the art facilities for the treatment of deafness and ear pain or discharge in adults and kids, perforated eardrums and mastoiditis. Being sensitive towards patient care, our team provides effective treatments for ENT related disorders.

ENT problems like ear ache, common cold, epistaxis, sore throat, etc. are very common. Over the years, this field has developed to a great extent and today more and more surgeries are performed by microscope and endoscope. Flexible endoscopic procedures are done to treat allergic rhinitis and vocal cord disorders. It is well-equipped to handle emergencies.

Cochlear Implant: A cochlear implant is an electronic device that restores partial hearing to individuals with severe to profound hearing loss who do not benefit from a conventional hearing aid. It is surgically implanted in the inner ear and activated by a device worn outside the ear. Unlike a hearing aid, it does not make sound louder or clearer. Instead, the device bypasses damaged parts of the auditory system and directly stimulates the nerve of hearing, allowing individuals who are profoundly hearing impaired to receive sound.

Working of Cochlear implants: Cochlear implants bypass damaged hair cells and convert speech and environmental sounds into electrical signals and send these signals to the hearing nerve.
A cochlear implant has two main components. An internal component that consists of a small electronic device that is surgically implanted under the skin behind the ear, connected to electrodes that are inserted inside the cochlea.
An external component, usually worn behind the ear, that consists of a speech processor, microphone and battery compartment.

The microphone captures sound, allowing the speech processor to translate it into distinctive electrical signals. These signals or "codes" are transmitted across the skin via radio waves to the internal electronic stimulator. The internal stimulator then sends the signals to the implanted electrodes in the cochlea. The electrodes’ signals stimulate the auditory nerve fibers to send information to the brain, where it is interpreted as meaningful sound.

Benefits: Cochlear implants are designed only for individuals who attain almost no benefit from a hearing aid. They must be 12 months of age or older (unless childhood meningitis is responsible for deafness).
Your will determine your candidacy for a cochlear implant and review what you may expect as a result of the cochlear implant. The implant team will also conduct a series of tests, including:

  • medicalEar (otologic) evaluation: The otolaryngologist examines the ear canal and middle ear to ensure that no active infection or other abnormality precludes the implant surgery.
  • medicalPhysical examination: Your otolaryngologist also performs a physical examination to identify any potential problems with the use of general anesthesia needed for the implant procedure.
  • medicalHearing (audiologic) evaluation: The audiologist performs extensive hearing tests to find out how much you can hear with and without a hearing aid.
  • medicalX-ray (radiographic) evaluation: Special X-rays are taken, usually computerized tomography (CT) or magnetic resonance imaging (MRI) scans, to evaluate your inner ear anatomy.


Cochlear implant surgery is usually performed as an outpatient procedure under general anesthesia. An incision is made behind the ear to open the mastoid bone leading to the middle ear space. Once the middle ear space is exposed, an opening is made in the cochlea and the implant electrodes are inserted. The electronic device at the base of the electrode array is then placed under the skin behind the ear.
