Cochlear Implant Activation in the Immediate Postoperative Period in the Operating Room

Abstract: Introduction Cochlear implant (CI) activation usually takes place at ∼ 30 days postoperative (PO). In our service, CI surgery is performed with local anesthesia and sedation, so activation is possible with the patient's cooperation, immediately after the CI surgery, still in the operating room (OR). Objective The objective of the present study was to provide the patient with hearing experience with the CI and to assess auditory perception immediately after surgery while still in the OR, as well as to compare impedance telemetry (IT), neural response telemetry (NRT), and comfort (C) level at two moments: in the OR and at the definitive activation, ∼ 30 days PO. Methods Nine adult patients (12 ears) with acquired (postlingual) deafness were included. Auditory perception was evaluated through the Ling Six Sound Check, musical instruments, and clapping, presented in two different programming maps, elaborated using t-NRT, and comparing IT, NRT, and C level between the two moments. Results We observed that while still in the OR, the patient can already present auditory detection and recognition responses. The values of IT, NRT threshold (t-NRT), and C on both dates differed, with statistical significance. Conclusion We concluded that it is possible to provide the patient with an auditory experience with the CI immediately after surgery, and that the auditory experience and the values of electrode IT, NRT, and C vary significantly between the two moments.
