Cochlear Implantation after Bacterial Meningitis in Infants Younger Than 9 Months

Table 1

Clinical characteristics and outcome of infants receiving cochlear implantation because of postmeningitic profound sensorineural hearing loss before the age of 9 months.

Case	Age at onset meningitis	ABR results	T1+ contrast cochlear MR image	T2 weighted cochlear MR image	Age at cochlear implantation	Side of implantation	Surgical findings	Result of implantation	Categories of auditory performance (CAP-NL)	Speech intelligibility rating (SIR)	Other sequelea
