No previous prospective study has investigated the detection of normal parathyroid glands (PTGs) and their features using real-time ultrasound (US). This study aimed to assess the preoperative US detection of normal PTGs in patients who underwent hemithyroidectomy.
Between August and October 2016, 44 patients underwent hemithyroidectomy using a low-collar incision, and 5 were excluded from the study. A single radiologist performed the preoperative US examination in all patients, and the surgical data for the PTGs were obtained by a single surgeon. Based on the surgical findings of PTGs, the preoperative US detection of PTGs was determined.
Of the 39 patients, 3 had no surgical data for PTG (n = 2) and the presence of parathyroid hyperplasia (n = 1). In the 36 remaining patients, in 3 patients, US identification of a normal PTG was corroborated by surgical findings, whereas in 2 patients, US findings differed from surgical findings, and in 31 patients, US did not detect a normal PTG. The successful US detection rate of normal PTG was only 8.3% (3/36).
US cannot be used for identification of normal PTGs.
以往尚无前瞻性研究利用实时超声（US）检测正常甲状旁腺（PTG）及其特征。本研究旨在评估行甲状腺半切术患者术前US对正常PTG的检测情况。
2016年8月至10月期间，44例患者采用低领切口行甲状腺半切术，5例被排除在研究之外。由一名放射科医生对所有患者进行术前US检查，并由一名外科医生获取PTG的手术数据。根据PTG的手术结果，确定术前US对PTG的检测情况。
39例患者中，3例无PTG手术数据（2例）以及存在甲状旁腺增生（1例）。在其余36例患者中，3例患者手术结果证实US识别出正常PTG，2例患者US结果与手术结果不同，31例患者US未检测到正常PTG。正常PTG的US成功检测率仅为8.3%（3/36）。
US不能用于识别正常PTG。
