Cervical nerve injury symptoms?

summary

Cervical nerve injury refers to the injury of sympathetic nerve, cerebral nerve and spinal nerve besides cervical spinal cord injury. Recurrent laryngeal nerve, brachial plexus, vagus nerve, accessory nerve, phrenic nerve and cervical sympathetic trunk are easy to be injured. After cervical nerve injury, there will be a series of neurological dysfunction, which is harmful to the health of the body and has a serious impact on the life, study and work of patients. Cervical nerve injury symptoms? Let's talk about it

Cervical nerve injury symptoms?

Unilateral recurrent laryngeal nerve injury was paralysis of abductor and adductor muscle, but the superior laryngeal nerve was still normal, so cricothyroid muscle could maintain abductor and adductor function. Hoarseness and phonation weakness are the only symptoms of unilateral recurrent laryngeal nerve palsy without dyspnea. The degree of cough weakness is consistent with hoarseness. Bilateral recurrent laryngeal nerve injury caused by trauma is rare, bilateral vocal cords can not be abducted, accompanied by severe dyspnea.

It mainly causes muscle paralysis of shoulder and upper arm, such as upper arm drooping, unable to abduct and rotate, forearm unable to bend and rotate, wrist and metacarpophalangeal joint unable to extend back, upper limb lateral numbness and sensory loss. The lower part of brachial plexus injury involves the 8th cervical nerve and the 1st thoracic nerve, which mainly causes paralysis of the intrinsic and flexor muscles of the hand. Atrophy is manifested as "claw shaped hand", and the hand and fingers can not bend. If sympathetic nerve is involved, Horner's syndrome may occur.

Unilateral vagus nerve injury occurred ipsilateral vocal cord paralysis, hoarseness, paroxysmal tachycardia and arrhythmia. There is no special risk of nerve rupture. Hematoma or shrapnel stimulation of the nerve trunk can lead to more serious clinical manifestations: slow breathing or even complete respiratory arrest and cardiac arrest in diastole. Emergency surgery should be performed to remove hematoma and foreign bodies.

matters needing attention

Light can be given physical therapy and nerve nutrition drugs, such as vitamin B1, vitamin B12, Mecobalamin, but most of the effect is not good. The patients were observed for 1 ~ 2 months, and the patients were treated by operation if they were invalid. Such as neurolysis, neuroanastomosis, tendon transfer and so on.
