Conclusion. Tthe proposed device can be useful for promoting safety during bipolar coagulation in many surgical procedures and/or regions. Objective. A new system that integrates a neural stimulator and a bipolar coagulator is proposed, to improve neural (facial nerve) safety during ENT surgical procedures. This study aimed to evuate the system. Materials and methods. A home-made constant current neural stimulator (0.1-2 mA, pulsed, duration 200 s), was connected via an automatic switch to a commercial bipolar microcoagulator (Medicon Instrumente mod. 101, Germany). Under general anesthesia, the extra-petrous portion of the facial nerve was identified in three rabbits. The adequate functioning of the device was tested via: 1) neural stimulation and EMG monitoring in basal conditions; 2) bipolar coagulation of connective tissue surrounding the facial nerve; 3) final assessment of the functional integrity of the nerve, via an intraoperative EMG and a postoperative evaluation. Results. Data obtained from all three rabbits provided adequate results in terms of neural stimulation, correct coagulation of juxta-nervous tissue, and functional integrity of the facial nerve, both intraoperatively and postoperatively.

Abstract

Conclusion. Tthe proposed device can be useful for promoting safety during bipolar coagulation in many surgical procedures and/or regions. Objective. A new system that integrates a neural stimulator and a bipolar coagulator is proposed, to improve neural (facial nerve) safety during ENT surgical procedures. This study aimed to evuate the system. Materials and methods. A home-made constant current neural stimulator (0.1-2 mA, pulsed, duration 200 s), was connected via an automatic switch to a commercial bipolar microcoagulator (Medicon Instrumente mod. 101, Germany). Under general anesthesia, the extra-petrous portion of the facial nerve was identified in three rabbits. The adequate functioning of the device was tested via: 1) neural stimulation and EMG monitoring in basal conditions; 2) bipolar coagulation of connective tissue surrounding the facial nerve; 3) final assessment of the functional integrity of the nerve, via an intraoperative EMG and a postoperative evaluation. Results. Data obtained from all three rabbits provided adequate results in terms of neural stimulation, correct coagulation of juxta-nervous tissue, and functional integrity of the facial nerve, both intraoperatively and postoperatively.
