UCSF Team Performs Surgery to Restore Iraqi Boy's Hearing
Ghazwan Al-Nadawi hasn’t heard his elder son speak in 19 months, since the day a missile attack in their native Baquba, Iraq, robbed the 3-year-old of his hearing and abruptly halted his nascent speech development.
But thanks to cochlear implant surgery performed on Friday by UCSF ear disorder specialist Lawrence Lustig, MD, the young boy, Mustafa Ghazwan, will soon be making up for lost time.
“He had started saying a few words [before his hearing loss], like ‘mama’ and ‘baba,’ but since then, we have used signs with our hands to communicate,” Al-Nadawi said through an interpreter on Friday, his hands shaking as he waited for Mustafa’s 90-minute surgery to end.
Cochlear implant surgery is a low-risk, outpatient procedure and the prosthetic unit is designed to last a lifetime. The implant — an electronic device that converts sound into an electric impulse to stimulate the auditory nerve — does not restore normal hearing, but can provide more access to speech information than a hearing aid can, according to the UCSF Douglas Grant Cochlear Implant Center, where Lustig serves as director.
Mustafa’s implant will remain turned off for about three weeks while the swelling in his right ear goes down, Lustig said. It is not known how well the boy will respond to the device, but Lustig expressed optimism.
“Our goal is just to get him to hear,” he said during a press conference after the surgery. “There’s a huge range in terms of people’s response to the implant.”
Al-Nadawi said his son was aware when he arrived at the hospital Friday morning that he would be undergoing a procedure, and that UCSF Medical Center staff had used dolls and other props to act out a mock cochlear implant surgery. But Mustafa did not fully understand the connection between the surgery and his ability to hear, Al-Nadawi said.
Mustafa’s hearing was destroyed in June 2007, when a US explosive device hit the building next door to where he lives with his parents and younger brother. The story of his condition eventually made its way to Cole Miller, a Los Angeles writer and founding director of No More Victims, which obtains medical sponsorships for Iraqi children injured in the war.

- A speech processor, which selects and arranges sounds picked up by the microphone.
- A transmitter and receiver/stimulator, which receive signals from the speech processor and convert them into electric impulses.
- An electrode array, which is a group of electrodes that collects the impulses from the stimulator and sends them to different regions of the auditory nerve.
