Xiao Jing originally intended to study abroad after the college entrance exam, but just after the exam, she felt uncomfortable in her throat and had trouble swallowing. Before facing the college entrance examination, she thought that the pressure of study was due to fire, did not pay much attention. These days, Xiao Jing’s left chin suddenly grew a bag. The local hospital found that she had a tumor on her left side of the throat and needed immediate surgery. She went to a number of hospitals, doctors said to open a 10 cm incision in the chin, some also said to cut off part of the jaw bone to remove the tumor. Xiao Jing knew that her face would be “broken” after the surgery, so she resolutely refused to operate. A few days ago, Xiao Jing came to Sun Yat-sen Memorial Hospital of Sun Yat-sen University by name. After careful examination, Professor Chen Weiliang of the Department of Oral and Maxillofacial Surgery told her that the tumor could be removed with a half-thumb-length opening below the ear, and the scar would be hidden, which made the family half-hearted and half-doubtful. After sufficient preoperative preparation, Chen Weiliang successfully removed the tumor, which was buried deep in Xiao Jing’s throat and about fist size, with the assistance of endoscope. Two days after the operation, Xiao Jing was discharged from the hospital without complications. Prof. Chen Weiliang said that the reason why a small incision can remove a large tumor is due to the assistance of endoscope. This high-definition endoscopic imaging system can clearly display some head and neck tumors that were previously located deep and out of reach of the naked eye, allowing complete removal of tumors with minimally invasive and concealed incisions and few postoperative complications. However, Chen Weiliang also reminded that not every patient is suitable for the endoscopic surgical treatment plan, which should be judged according to the condition, tumor nature, tumor site and the patient’s physical condition.
