Nine out of fifteen cases having division of the spinal component of the accessory nerve and the upper cervical motor roots as treatment for spasmodic torticollis had residual movements in the sternomastoid of sufficient magnitude to make further surgery necessary before the muscle was effectively paralysed. These observations imply a more complex innervation for the muscle than is to be found in most anatomical texts.
15例中有9例采用副神经脊髓支和上颈段运动神经根切断术治疗痉挛性斜颈,在胸锁乳突肌有效麻痹之前,该肌仍有足够幅度的残留运动,因此有必要进一步手术。这些观察结果表明,该肌肉的神经支配比大多数解剖学教科书中所描述的更为复杂。
