The sequelae of mediastinal surgery generally include incision scars and numbness and pain, hoarseness and abnormal swallowing reflexes due to damage to the recurrent laryngeal nerve, diaphragmatic paralysis and dyspnea due to damage to the phrenic nerve, and sequelae caused by the mediastinal lesion itself. 1. Mediastinal surgery, whether minimally invasive incision or traditional large incision, has varying degrees of surgical incision scars and numbness and pain and other sequelae. 2. Invasion of upper mediastinal lesions or damage to the recurrent laryngeal nerve during surgery can lead to sequelae such as hoarseness and abnormal swallowing reflex. 3. Violation of the middle mediastinal lesion or damage to the phrenic nerve during surgery can lead to sequelae such as diaphragmatic paralysis and dyspnea. 4. Sequelae caused by mediastinal lesion itself can be aggravated after surgery, such as thymoma can be left after surgery with aggravated symptoms of myasthenia gravis, malignant mediastinal tumors continue to have sequelae such as compression of mediastinal tissues and structures after surgery for failure to completely resect the tumor. What are the sequelae of mediastinal surgery, it is recommended to go to the thoracic surgery department of the hospital for further consultation.
