The patients who received CIs did so with parental informed consent and as soon as an accurate diagnosis was obtained and all pre-operative surgical protocols had been completed, Dr. Colletti and his team reported. Patients’ hearing function was assessed at regular intervals throughout the 48-month period of post-implant follow-up.
Dr. Colletti stressed to ENT Today that additional in-depth electrophysiological evaluations were performed in order “to obtain the correct information on the hearing levels [in children] under six months of age.” Such testing, he noted, helped to ensure that children were optimal candidates for CI surgery.
The mean age of the patients in Group 1 (3.9 months) “is the lowest described in the literature,” Dr. Colletti reported. And in those infants, some of the most impressive results were observed. For example, speech perception scores in Group 1, as measured by the Categories of Auditory Performance (CAP II) test, were statistically significantly higher than in all of the other implanted children, the investigators reported (P <0.001).
