The sequelae of spinal cervical spondylosis may include injury to the superior or recurrent laryngeal nerve, pleural injury, and hematoma with dysphagia. 1. Superior laryngeal nerve or recurrent laryngeal nerve injury: Superior laryngeal nerve injury sometimes occurs in anterior upper cervical spine surgery, which usually manifests as choking and coughing when drinking water after the surgery. Lower cervical spine surgery is prone to laryngeal nerve injury, often manifested as hoarseness and breathlessness after surgery. 2. Pleural injury: When the lower cervical spine is revealed during surgery, it is easy to cause injury to the top of the pleura. Pneumothorax may occur after rupture and should be treated immediately. 3. Hematoma and dysphagia: Blood vessels may be damaged during surgery, causing bleeding and formation of hematoma. If the hematoma is not absorbed well, it may cause adhesions in the esophagus, resulting in symptoms such as difficulty in swallowing. When patients undergo spinal cord cervical spondylosis surgery, they should go to the hospital immediately to receive professional treatment from the doctor if any discomfort occurs.
