简要总结
The investigators hypothesized that, sometimes the posterior branch of the recurrent laryngeal nerve may also have motor function. The investigators aimed to evaluate motor function of the branches in the branching recurrent laryngeal nerves in this study.
详细描述
This study group consisted of consecutive patients, undergoing thyroid and parathyroid surgery with IONM. Both anterior and posterior branches of the recurrent laryngeal nerves were assessed separately by both electromyography endotracheal tube for adduction and finger palpation for detection of laryngeal twitch due to posterior cricoarytenoid abduction. The recurrent laryngeal nerves having motor function only in the anterior branches were defined as group 1, whereas the nerves having motor function both in the anterior and posterior branches were as group 2.

结局指标
主要结局
The evoked EMG potentials of the branches of the recurrent laryngeal nerves as microvolt, by intraoperative neuromonitoring.
时间窗: intraoperative
The nerves , due to having motor functions whether on their anterior or posterior branches, were divided into two groups. The amplitudes of the anterior and posterior branches within the group 2 were compared.
次要结局
- The diameters of the branches of the recurrent laryngeal nerves.(intraoperative)
- The branching distances of the recurrent laryngeal nerves.(intraoperative)
