The laryngeal motor center of the bilateral cerebral cortex has a nerve bundle connected with the two sides of the nucleus ambiguus, so each muscle receives impulses from both sides of the cerebral cortex. Therefore, laryngeal paralysis caused by cortical lesions is very rare in clinic. Cerebral hemorrhage, basilar artery aneurysm, inflammation of posterior cranial fossa, tumors of medulla oblongata and pons can cause vocal cord paralysis.

The laryngeal paralysis caused by recurrent laryngeal nerve or vagus nerve leaving the jugular foramen or even separating from the recurrent laryngeal nerve is peripheral. Vocal cord paralysis can be caused by skull base fracture, thyroid surgery, various kinds of neck and throat trauma, laryngeal, neck or skull base benign and malignant tumor compression, mediastinal or esophageal metastatic tumor, nasopharyngeal carcinoma invading skull base, pulmonary apex tuberculous adhesion, pericarditis, peripheral neuritis, etc.

matters needing attention

Vocal cord paralysis can be the result of the lesion of nucleus ambiguus and its superior pathway, trunk of vagus nerve or recurrent laryngeal nerve. Recurrent laryngeal nerve paralysis can be caused by cervical and thoracic lesions, trauma, thyroidectomy, neurotoxin (lead), neurotoxic infection (diphtheria), cervical spine injury or surgery, or viral diseases.
