PREOPERATIVE DIAGNOSIS: Bilateral severe to profound sensorineural hearing loss Sequaelae of pneumococcal meningitis POSTOPERATIVE DIAGNOSIS: Bilateral severe to profound sensorineural hearing loss Sequaelae of pneumococcal meningitis NAME OF PROCEDURE: Bilateral cochlear implantation with Advanced Bionics HiRes 90K multi-channel device INTRAOPERATIVE FINDINGS: Normal mastoid anatomy bilaterally with facial nerve present along anticipated course and round windows were calcified bilaterally. INDICATIONS: The patient is a 9-month-old male who was previously hospitalized with pneumococcal meningitis three months ago. Subsequent auditory brainstem response testing on multiple occasions revealed bilateral severe to profound sensorineural hearing loss, with normal middle ear functioning. Hearing aid trials were without significant benefit. After a discussion of the risks, benefits and alternatives, the patient was consented to for insertion of an Advanced Bionics cochlear implant device.
Expert Solution
Step 1

cochlear implantation after bacterial meningitis in very young infants.  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.
