In this paper, the authors discuss the risks of lesions to the external branch of the superior laryngeal nerve during surgical procedures on the thyroid gland. These lesions result in significant functional impairment consisting on the patients' impossibility of emitting high-pitched sounds, an easy tiredness in vocalizing, huskiness, or a combination of these symptoms. Recently, in effect, with the increasing use pre and postoperatively of newer diagnostic tools such as electromyography (EMG) of the cricothyroid muscle, a fairly high incidence of permanent or temporary, including single or bilateral lesions to this nerve was demonstrated. The necessity of using appropriate surgical techniques with the objective of avoiding or markedly reducing the incidence of lesions to the superior laryngeal nerve is discussed in detail by the authors.
在本文中，作者讨论了甲状腺手术过程中喉上神经外支损伤的风险。这些损伤会导致严重的功能障碍，包括患者无法发出高音、发声时容易疲劳、声音嘶哑或这些症状的组合。实际上，近年来，随着术前和术后越来越多地使用诸如环甲肌肌电图（EMG）等更新的诊断工具，已证实该神经发生永久性或暂时性（包括单侧或双侧）损伤的发生率相当高。作者详细讨论了采用适当手术技术以避免或显著降低喉上神经损伤发生率的必要性。
