目的　研究甲状腺假被膜的解剖学形态特点，探讨其临床意义。  方法    在95例单侧甲状腺叶切除术中，观察甲状腺假被膜的解剖学形态，甲状腺假被膜与真被膜、甲状腺血管、甲状旁腺和喉返神经的关系。  结果    在甲状腺下静脉、中静脉和上血管附着于腺体的部位，甲状腺假被膜呈“系膜”样结构附着在腺体上，切除腺叶后观察“系膜”呈“C”型的延续平面，甲状腺下静脉、中静脉和上血管分别自系膜缘穿出，喉返神经、甲状腺下动脉、甲状旁腺位于“系膜”的“C”型圈内。  结论    对甲状腺假被膜的解剖新认识，有助于术者安全的完成甲状腺手术，特别是被膜解剖技术的应用。

Objective　To investigate anatomic features of the false thyroid capsule, and discuss it's clinical significance.    Methods　In 95 cases of unilateral total thyroid lobectomy, the anatomical structures of the false thyroid capsule and its relationship with thyroid vessels, parathyroid, recurrent laryngeal nerves were observed.    Results　At the sites of inferior thyroid vein, middle thyroid veins and superior thyroid vessel attached to thyroid gland, false thyroid capsule showed a meso-like structure attached to the thyroid glands. After removing the gland lobe, a continuous platform of false thyroid appeared, with the shape of "C", and the thyroid vessels emerged from the edge of meso-like fascia respectively. Among the circle of "C"- like fascia, recurrent laryngeal nerve, inferior thyroid artery, the parathyroid glands located in it.    Conclusions　The anatomy awareness of the false thyroid capsule is benefit to safety thyroid surgery, especially in capsular dissection.
