球体瘤又名非嗜铬细胞瘤,病理特点之一是成串的肿瘤细胞散布在丰富的毛细血管网中,有家族遗传性,遗传性球体瘤的特征是多中心发病,占30%以上。头颈部球体瘤包括颈动脉体瘤、鼓室或颈静脉球体瘤及迷走神经体瘤。肿瘤生长缓慢,死亡率低,但可包绕邻近的血管、神经及向颅内侵犯。手术难度较大,易损伤血管和神经。早在75年以前就有人认为外科治疗的后果比它的自然病程更差,因此, Spheroid tumor, also known as non-pheochromocytoma, is characterized by a series of tumor cells scattered in the rich capillary network, a family hereditary, hereditary spherical tumor is characterized by multi-center disease, accounting for more than 30%. Head and neck spheroid tumors include carotid body tumors, tympanic or jugular bulbous tumors, and vagal tumors. Tumors grow slowly and have a low mortality rate, but can enclose neighboring blood vessels, nerves, and invade the brain. Surgery is more difficult and easily damages blood vessels and nerves. As early as 75 years ago, some people thought that the consequences of surgical treatment were worse than its natural course. Therefore,
