The frequency of the ectopic parathyroid glands has been reported to be 7-46% by anatomists or surgeons, while the proper frequency is still unknown. Recently the diagnostic methods of hyperparathyroidism have been developed, and many surgeons select total parathyroidectomy for renal hyperparathyroidism. Therefore the frequency of the ectopic glands has been supposed to be higher than that recognized previously. We investigated 97 patients with renal hyperparathyroidism, and detected 60 ectopic glands in 34 patients (35.1%). The ectopic glands existed in the mediastinum, intrathyroid, carotid sheath, post-pharynx, para-esophagus, and other regions. We describe the features of procedures for detecting ectopic glands. Using non-invasive examination, including ultrasonography, scintigraphy (T1 201-Tc 99 m), and MRI, will be a great assistance in the diagnostic procedures.
解剖学家或外科医生报告异位甲状旁腺的发生率为7%-46%，但其确切发生率仍不清楚。近年来，甲状旁腺功能亢进症的诊断方法不断发展，许多外科医生选择对肾性甲状旁腺功能亢进症患者进行甲状旁腺全切除术。因此，人们认为异位甲状旁腺的发生率高于以往的认识。我们对97例肾性甲状旁腺功能亢进症患者进行了研究，在34例患者（35.1%）中检测到60个异位甲状旁腺。异位甲状旁腺存在于纵隔、甲状腺内、颈动脉鞘、咽后、食管旁及其他区域。我们描述了检测异位甲状旁腺的手术特点。使用包括超声检查、闪烁扫描（铊201-锝99m）和磁共振成像在内的非侵入性检查，将对诊断过程有很大帮助。
