Objective: To present the experience in adult auditory brainstem implantation

Patients and Methods: The data of 2 patients with deafness who underwent auditory brainstem implantation on the base of the NRMCO in 2024 were evaluated. Type of pathology, previous surgeries, intraoperative findings, complacations and audiological outcome were evaluated. The follow-up period was 10 months.

Results: In both cases etiological factor was trauma (in one case with associated meningities), that caused total cochlear ossification. In one case ineffective cochlear implantation was performed before. Both patients underwent successful placement of an auditory brainstem implant using a retrosigmoid craniotomy approach. There were no side reactions from ABI implants in these cases intraoperatively. However, in early postoperative period in one case muscle contruction was revealed from 4 electrodes, also patient faced on with IX bilateral paralysis. The audiological results in this case was moderate. In the 2nd case no significant complications were observed except for enlargement of ventricles on the 20th day postop. Ventriculoperitoneal shunting was performed. The audiological results in the patient were good with speech recognition score 60%. The 2nd patient showed poor results without significant speech recognition.

Conclusions: An ABI has proven to be a safe procedure without serious complications. ABI can provide useful hearing in patients when CI is impossible. The entire ABI process should be handled by a multidisciplinary team with extensive experience in cerebellopontine angle tumour surgery and cochlear implantation in adults and children.
