The risks of cervical compression nerve surgery are as follows: first, injury to the superior laryngeal nerve, it is easy to damage the superior laryngeal nerve when revealing the upper cervical vertebrae, and the injury manifests itself as aspiration and choking, and the pulling injury can be recovered on its own, and the unilateral nerve severance injury can be compensated for by adapting to the injury, and choking will gradually be relieved or disappeared; second, injury to the retrograde laryngeal nerve, the retrograde laryngeal nerve is located in the lower cervical vertebrae in the trachea and esophageal groove, and it is easy to damage it in the cervical 6-thoracic 1 vertebrae section surgery, and the performance It is easy to be injured during the surgery of cervical 6 thoracic 1 vertebrae, which manifests as vocal cord paralysis and dysphonia. Strain injuries are mostly temporary and can recover on their own. Cutting double or contusion injury will leave permanent inflammation, and the pulling injury is mostly recovered within 2-4 weeks; third, the implanted bone block partially slips off, and the cervical implant materials include autologous iliac bone, allograft bone, artificial bone, etc. Allograft bone is easy to be absorbed, causing the cervical vertebra to be absorbed, causing the cervical cord to be paralyzed. Allograft bone is easily absorbed, causing narrowing of the intervertebral space and angular deformity of the cervical spine and secondary spinal cord compression.
