Tonsillectomy and adenoid tonsillectomy are one of the most common operations in otolaryngology. The postoperative pain caused by local inflammation and nerve stimulation triggered by the operation is a common complication after this type of operation, which seriously affects the patient’s quality of life and satisfaction afterwards. At present, various types of analgesics (opioids, steroids, non-steroidal anti-inflammatory drugs, etc.), local anesthetic sprays and local infiltration anesthesia are mainly used for postoperative analgesia.The glossopharyngeal nerve is the main nerve that innervates the tonsils and sensation around the tonsils, so blocking this nerve can achieve the purpose of analgesia.The research on glossopharyngeal nerve block to reduce pain after Tonsillectomy has gradually increased in recent years. Now we are focusing on the analgesic principle and block methods, analgesic effects and other aspects are reviewed.
