摘　　要：目的:明确C3、C4颈丛斜方肌支对斜方肌中下部分的支配作用。方法:选择73例接受不同颈清术式的患者,其中18例保留副神经及颈丛斜方肌支(A组);11例仅保留副神经(B组);17例保留C3、C4斜方肌支(C组);27例切除副神经及C2-C4斜方肌支(D组),分别于术后2周、6个月、1年及2年检测各患者的肩功能和斜方肌肌电指标进行比较。结果:A组术后肩功能恢复最好;C组患者斜方肌中下部分的功能与B组无明显差异,且上部分功能优于D组。结论:C3、C4颈丛斜方肌支对斜方肌中下部分有支配作用,这种支配可使患者术后的部分肩功能得到明显改善,其改善程度不亚于仅保留副神经的患者。Objective： To evaluate the innervation of transverse and ascending parts of the trapezius muscle from the cervical plexus. Methods： 73 patients who underwent neck dissection were included. 18 patients preserved both accessory nerve and the cervical branches, 11 preserved accessory nerve, 17 preserved cervical branches and 27 sacrificed both of them. All patients were assessed subjectively at 2 weeks, 6 months, 12 months and 24 months after operation, using a questionnaire and an electromyograghy method. Results： The function of the transverse and ascending parts of the trapezius muscle of the patients who preserved cervical branches was not worse than the men who preserved accessory nerve. Conclusion： C3, C4 contributions innervated the transverse and ascending parts of the trapezius muscle independently.
