Operative approach
Based on the results of the MDT discussion, surgeons employed different operative approaches depending on the patient’s situation. However, the surgeon planned to perform the grade (c) surgery method in one of the patients. However, this patient could not accept the symptom of aural fullness, and thus grade (b) surgery method was adopted. The other patients agreed with the results of the MDT discussion and accepted the surgical methods. The intraoperative time fluctuated 3.2 ± 1.0 hours. Intraoperative neural response telemetry (NRT) showed that the surgery of all cochlear implant was performed successfully. Smooth anesthesia and operation without complications were achieved in all patients (Table 2).
