Cause for concern:
A possible (but not proven) link is found
between cochlear implants and meningitis
On July 24, 2002, the U.S. Food and Drug Administration issued a notification that it had received reports of a possible link between cochlear implants and the occurrence of bacterial meningitis.
The FDA is investigating an increase in cases of meningitis among deaf people who have received cochlear implants. Some 55,000 to 60,000 implants are in use worldwide, 22,000 of them in the United States. Children account for around half of the total number of implantees.
Between 1984 and 1999, there were only sporadic cases reported in the U.S., some years without any cases at all being reported, but since 2000, 8 have been reported.
According to Philip J. Hilts New York Times article (August 3), Dr. Eric Mann, who heads the FDA branch that oversees ENT devices, said "that was hard to determine whether the meningitis cases were linked to the implants. Some people with cochlear defects are susceptible to meningitis, which is a leading cause of deafness, and recurrences are not uncommon."
Even so, the FDA advised implantees to consider getting vaccinated against meningitis. In the same alert issued on July 24, it advised CI and ENT doctors to be alert for the symptoms of meningitis.
In response to the concerns raised abroad about the possible link between its Clarion HiFocus implant and meningitis, Advanced Bionics Corporation removed its HiFocus I and II models from the market in France, Germany, Japan, and Spain, and subsequently, on August 6, stopped selling Clarion implants in the U.S., although the FDA said it would allow the company to re-market the Clarion HiFocus implant without electrode positioners.
This positioner, introduced in 1999, is the part of the Clarion HiFocus model that worries some doctors. Its used to insert the electrodes into the cochlea, and may leave gaps ("dead space") that can encourage buildup of bacteria that migrate to the fluid that coats the brain. As Hilts notes: "An infection there, by pneumococcal bacteria, is defined as meningitis."
If the symptoms (fever, lethargy, stiff neck, headache, and irritability) are correctly and quickly diagnosed, meningitis can be successfully treated with antibiotics. But if the diagnosis isnt made early enough, it can be fatal.
