Cochlear implant after bacterial meningitis

Abstract

CI was a safe procedure without surgical complications in the present study. It is possible to restore auditory capacity and speech performance to a degree comparable to children undergoing implantation for other reasons. A statistically important variable is secondary CNS involvement. The rehabilitation program after CI should be adjusted according to these additional handicaps. It is recommended to screen meningitis patients as fast as possible to identify those with hearing loss and initiate treatment with hearing aids or CI.

Cochlear implant performance in children deafened by congenital cytomegalovirus—A systematic review

“…The critical appraisal of the 30 studies is presented in Table . One study was a prospective cohort study, all other studies were retrospective studies.…”

“…One study was a prospective cohort study, all other studies were retrospective studies. Twenty‐three studies included children with cCMV‐related hearing loss as well as children with other causes of hearing loss . Eleven studies directly compared a cCMV‐group to a non‐cCMV‐group .…”

“…Eleven studies directly compared a cCMV‐group to a non‐cCMV‐group . The non‐cCMV group included children with various causes of SNHL in five studies, and children with hereditary SNHL due to connexine 26 (Cx26) mutation in six studies . In one study, a comparison could be distracted, yet no statistical analysis .…”

“…Blinding was not performed in any of the studies, as no randomised controlled trials were included. Three studies were assessed as susceptible to selection bias, three were assessed as selective inclusion of non‐missing data in a retrospective cohort, all other 24 were assessed as having no selection bias …”

“…5 compared a cCMV-group to a non-cCMV-group. 5,13,[18][19][20][21][22][24][25][26][27] The non-cCMV group included children with various causes of SNHL in five studies 13,[18][19][20]22,23,[28][29][30][31]33,[35][36][37]39,40 , and children with hereditary SNHL due to connexine 26 (Cx26) mutation in six studies. 5,21,[24][25][26][27] In one study, a comparison could be distracted, yet no statistical analysis.…”
