Hearing configuration in children with cCMV infection and proposal of a flow chart for hearing evaluation

Tijdschriftbijdrage - Tijdschriftartikel

OBJECTIVE:

This study had three main goals: (1) to determine the hearing configuration in hearing-impaired children born with a congenital CMV (cCMV) infection, (2) to see whether auditory neuropathy spectrum disorder (ANSD) was present, and (3) to propose a flow chart for the follow-up of hearing in children with cCMV.

DESIGN:

Hearing configuration and the presence of ANSD in cCMV infected children was analysed. Selection criteria were: hearing-impaired children with a regular audiometric follow-up for at least 36 months, no other major risk factors for hearing loss, a normal middle-ear status, and an appropriate behavioral response to the given pure-tone stimuli.

STUDY SAMPLE:

Out of a cohort of 206 cCMV infected children, 18 hearing-impaired children were selected.

RESULTS:

Audiograms of all children showed a flat configuration of SNHL: the slope between octave bands was never greater than 10 decibels. None of the 18 children were found to have ANSD.

CONCLUSIONS:

Hearing impairment in cCMV infants affected all frequencies equally and ANSD does not appear to be a feature of cCMV infection. A flow chart for hearing follow-up in children with cCMV infection was suggested in order to provide guidance, improve uniformity in follow-up, and to make results easier to compare.
