“…Almost all bacteria species causing meningitis have been associated with permanent postmeningitic hearing loss, but this complication is most frequently found in S. pneumoniae, N. meningitides, and H. Influenza infections [6, 15, 16]. The prevalence of meningitis caused by these bacteria has decreased after the implementation of vaccination programmes in western countries [15, 17, 18]. The patients described in the current study also received vaccines against S. pneumoniae, N. meningitides, and H. Influenza.…”

Objective. To describe the audiological, anesthesiological, and surgical key points of cochlear implantation after bacterial meningitis in very young infants. Material and Methods. Between 2005 and 2010, 4 patients received 7 cochlear implants before the age of 9 months (range 4–8 months) because of profound hearing loss after pneumococcal meningitis. Results. Full electrode insertions were achieved in all operated ears. The audiological and linguistic outcome varied considerably, with categories of auditory performance (CAP) scores between 3 and 6, and speech intelligibility rating (SIR) scores between 0 and 5. The audiological, anesthesiological, and surgical issues that apply in this patient group are discussed. Conclusion. Cochlear implantation in very young postmeningitic infants is challenging due to their young age, sequelae of meningitis, and the risk of cochlear obliteration. A swift diagnostic workup is essential, specific audiological, anesthesiological, and surgical considerations apply, and the outcome is variable even in successful implantations.

“…Imaging assessment of labyrinthitis ossificans is essential for surgical planning because these patients benefit from urgent referral for evaluation and cochlear implantation before obstruction of the cochlea occurs (37). Early implantation before the onset of substantial obstruction is necessary to achieve optimal electrode insertion and avoid the need for complex alternative surgical approaches, which have more variable outcomes.…”

Cochlear implantation is the only U.S. Food and Drug Administration-approved treatment for children with marked bilateral sensorineural hearing loss. It provides auditory benefits that range from simple sound detection to substantial word understanding. Improved hearing through cochlear implantation has been demonstrated to enhance the rate of language acquisition, enable development of spoken language, and advance literacy in deaf children. Magnetic resonance imaging and computed tomography both have roles in the preoperative assessment of inner-ear abnormalities, cochlear nerve deficiency, and variant anatomy that may affect the decision to implant and the prognosis for auditory improvement and increase the risk for complications. Most cochlear abnormalities may be successfully treated with cochlear implantation, but the presence of a cochlear malformation may increase the risk for intraoperative cerebrospinal fluid leakage and postoperative bacterial meningitis. Eighth-nerve deficiency correlates with poor auditory outcomes and may affect eligibility for cochlear implantation. Another important consideration for implantation is the presence of labyrinthitis ossificans in some children with deafness resulting from bacterial meningitis, which may cause obstruction that limits electrode insertion. Anatomic variations of the facial nerve or middle-ear cavity, which are more common in syndromic patients, may also affect the surgical approach and make implantation difficult.

“…Also, the role of time between PMD and implantation is arguable. Some survey recommended that CI should be performed after diagnosis of PMD as soon as possible and other suggested late approach (14).Young et al showed that early bilateral simultaneous CI in children with PMD increases the likelihood of binaural hearing and ensures implantation of the better ear in this population of children whose course is often complicated by formation of scar tissue and ossification within the cochlea (15). Regarding to the results of present study and similar studied we conclude that children with post meningitis deafness could be Benefited from CI.…”
