Command Hospital Pune has achieved a significant milestone by successfully performing two piezoelectric bone conduction hearing implants, marking the first instance of such procedures in a government hospital in India.

• The piezoelectric bone conduction hearing implant system is an expensive implantable medical device designed for patients with hearing impairments, including those with conductive loss (such as aural atresia), mixed hearing loss, and single-sided deafness (SSD).
  • Aural atresia is a congenital condition that affects the development of the ear, specifically the ear canal.
    • In individuals with aural atresia, the ear canal fails to form properly or is completely absent, leading to significant hearing impairment or deafness in the affected ear.
  • Single-sided deafness is a condition in which an individual experiences complete or near-complete hearing loss in one ear, while the other ear has normal or near-normal hearing.
• Piezoelectricity is a property of certain materials that induces an electric current when mechanically stressed.
