Monopolar electrosurgery below the neck in cochlear implant recipients can be performed without damage to the internal cochlear stimulator, electrode array, and the cochlear nerve.
Prospective pre- and postintervention electrically evoked compound action potential (ECAP) study of cochlear nerve function and behavioral sound perception assessment.
Neural response telemetry (NRT) was used to measure ECAPs before and after the use of monopolar electrosurgery during coronary artery bypass surgery to assess prosthetic device function and electrophysiologic function of the cochlear nerve. In addition, electrode voltage impedances and behavioral sound perception was measured at the same time intervals.
ECAPs, behavioral sound perception, and electrode voltage impedances were within the normal range, within compliance, and similar preoperatively and on postoperative day 6.
The studies reported herein were a series of measurements designed to test neural integrity and prosthetic device function before and after the use of monopolar electrosurgery. With appropriate precautions, use of monopolar electrosurgery below the neck in cochlear implant recipients can be performed safely.
人工耳蜗植入受者在颈部以下进行单极电外科手术时不会对内部耳蜗刺激器、电极阵列和耳蜗神经造成损伤。
对耳蜗神经功能进行干预前后的前瞻性电诱发复合动作电位（ECAP）研究，并进行行为性声音感知评估。
在冠状动脉搭桥手术中使用单极电外科手术前后，采用神经反应遥测（NRT）测量ECAP，以评估假体装置功能和耳蜗神经的电生理功能。此外，在相同时间间隔测量电极电压阻抗和行为性声音感知。
ECAP、行为性声音感知和电极电压阻抗在术前和术后第6天均在正常范围内，符合要求且相似。
本文报道的研究是一系列旨在测试单极电外科手术前后神经完整性和假体装置功能的测量。采取适当的预防措施后，人工耳蜗植入受者在颈部以下进行单极电外科手术可以安全进行。
