为防止根治性颈廓清术的后遗症和并发症,曾有不少学者对之进行了改进,其中颈后三角淋巴系统和副神经的处理是很多学者所注意的问题之一。现就与此有关的问题略加综述。一、切除副神经的永久性后遗症——“肩综合征”(“shoulder syndrome”):此综合征是由于颈廓清时切除副神经,引起斜方肌麻痹而发生。有谓斜方肌除受副神经支配外,尚有颈丛(C_3～C_4)的运动支供给,但经Carenfelt等(1981)观察,切除副神经后肩外展功能严重受到限制,肌电图和临床检查等都不支持斜方肌多源神经支配的观点。这种肩综合征的临床特点是
In order to prevent the sequelae and complications of radical neck dissection, many scholars have improved it. The treatment of the posterior trigoneal lymphatic system and accessory nerves is one of the issues that many scholars pay attention to. A brief summary of the issues related to this is now available. First, the permanent sequelae of the resection of the accessory nerve - “shoulder syndrome” (“shoulder syndrome”): This syndrome is due to the removal of the accessory nerve during the neck dissection and paralysis of the trapezius. There is a claim that the trapezius muscle is dominated by the accessory nerves, but there is still a supply of motion branches of the cervical plexus (C_3~C_4), but Carenfelt et al. (1981) observed that the abduction of the accessory nerve is severely limited in the abduction function. Neither the clinical examination nor the support for the viewpoint of multi-source innervation of the trapezius muscle. The clinical feature of this shoulder syndrome is
