In 1989 Dr. M. Farhadi and his Colleagues in the "Iranian Institute for Science and Research Development" set out to develop some rehabilitation materials for post operative rehabilitation and educating of staff.In March 1991 a post lingually patient who ws deafend in a traffic accident was implanted by MSP 22 channel.

Up to now 580 patients, ranging from 15 months old to 52 years old, have been fitted with the device. Success of the procedures has given hope to 530 patients on the waiting list. Rising demand made the  cochlear implantation  team set up training  courses  for highly-qualified surgeons, which resulted in establishment of another center in Mashad in 1997, where 15 patients have so far received implant.

It was not until 1999 when a third center in Tehran, BaghiyataIlah hospital ,started up. It goes without saying that the trend is upwards. The cochlear Implantation team consists of  ENT surgeon, audiologist,  speech pathologist, psychologist and  psychiatrist.
