Abstract:
Objective To investigate the technology learning curve of thyroid cancer intraoperative nerve monitoring aiming to reduce the recurrent laryngeal nerve injury complication.Methods Eighty-two cases of thyroid cancer accepted thyroid cancer radical mastectomy or combined radical operation,dissected 147 recurrent laryngeal nerve,used intraoperative nerve monitoring technology,monitored recurrent laryngeal nerve function with four steps method.The recurrent laryngeal nerve injury can be diagnosed when the intraoperative signal decay rate was more than 50％.The damage point and reason can be judged.Results The recurrent laryngeal nerve search time was 0.5 to 2 minutes.The recurrent laryngeal nerve damage rate was 2.7％.Recurrent laryngeal nerve damage cases were all diagnosed during the operation.Recurrent laryngeal nerve damage points were all located in the throat or approaching into the throat.The damage reasons were pull,tumor adhesion,thermal damage and clamp.The technology learning curve of thyroid cancer intraoperative nerve monitoring formatted through search time and injury cases of each group according to the time sequence.Recurrent laryngeal nerve search time and injury cases were obviously downtrend.Conclusions The technology learning curve of thyroid cancer intraoperative nerve monitoring existed.It can be used to protect recurrent laryngeal nerve.
