First auditory brainstem implant in the Czech Republic

In the Czech Republic, the first implantation of a stimulation electrode in to the brainstem was performed on 11 January 1999 in the Department of ORL, Head and Neck Surgery, The First Medical Faculty, Charles University in Pr ague, University Hospital Motel. The selected patient was a 40-year-old woman with neurofibromatosis type 2 (NF2) who had previously undergone bilateral vestibular schwannoma surgery. Both tumours had been radically removed, the left-sided tumour in 1987, th e right-sided one in 1988. She had been completely deaf since the last oper ation, i.e., for 11 years. The surgery was realized by the international co operation of three teams. Placement of the electrode pad of the Nucleus CI2 1+1M system on the ventral and dorsal cochlear nuclei was performed. Electr ically evoked auditory brainstem responses (EABRs) proved the correct posit ion of the electrode array. The post-operative course was uneventful. Six weeks after the surgery the p atient received her speech processor. Since that time, the patient already absolved several sessions of a speech processor tune-up. She uses the devic e as an aid in lip-reading. No adverse or pathological side effects have be en observed. The patient was the 45th person in Europe to receive an ABI an d the first in the Czech Republic.
