After two years of living virtually in silence, the small ENO Nicolás Silva Zuñiga noticed for the first time the voice of his mother. The exciting moment was experienced last Friday of April 12, after the activation of an implant cochlear of her left ear by the prominent Otolaryngologist Carlos Stott in the Clinical Hospital of the University of Chile.

The most shocking is that Nicolas today can identify the presence or absence of sounds and hear the voices of their loved ones,»said Dr Stott.
