Digital endoscopy technology keeps “face” for patients


China Youth Daily Client News (China Youth Daily · China Youth Network reporter Sun Haihua) Recently, using endoscopic technology, the Air Force Military Medical University Stomatological Hospital has performed tumor resection and jawbone reconstruction surgery for patients with maxillofacial tumors. The digital design used in this operation is the first case in China.

Ms. Xing, 36, has swollen on her left side since last year. Ms. Xing thought she was getting angry. She had not seen improvement after taking anti -inflammatory drugs, and her swelling became heavier. Touching from the mouth, the affected area is very hard. When going to the Stomatological Hospital of the Air Force Military Medical University, Dr. Wu Wei, deputy director of the Department of Mandarin Facial Oncology, was diagnosed. Ms. Xing suffered from glazed cytoma -patients with semi -sidelines have been eroded by the tumor, and fractures at any time. The tumor has even approached the mandibular joint, causing patients to open their mouths.


“The nature of glazed cytoma is from benign and malignant critical points, and it is easy to recur.” Dr. Wu Wei introduced that the conventional treatment method is to intercept the mandible and transplant the bone from the calf to reconstruct the mandibular bone. However, this method has a large trauma and a long course of disease. Due to the large incision, patients even have symptoms such as local facial paralysis, which also makes Ms. Xing very worried. Considering the patient’s condition, Wu Wei decided to try to combine digital design with endoscopic technology, and perform huge tumor resection and jaw reconstruction surgery for patients from the mouth.

During the operation, experts cut the mucous membrane in the oral cavity and combined with endoscopy technology to completely remove the tumor and the eroded bone. Then, a section of fibula with blood vessels from Ms. Xing’s left leg, combined with digital technology, accurately shaped the bone into the shape of the lax mandibular bone, and then put it in the oral cavity in the defective mandibular bone. In front of the patient’s left ear, the expert designed a 1 cm long tiny incision. Under the guidance of the endoscope, the fibula and the residual joint head were accurately connected to reconstruct the patient’s temporal mandibular joint. Because the affected space is small and the field of vision is limited, the size of the fibula petals must be accurately matched and strictly sew, and there is no chance of re -adjustment.


In order to meet the needs of patients with dental planting, the implanted fibula is also overlapped, which leads to a very short blood vessels that can be consistent. Experts made a incision of less than 3 cm in the concealment of the patient’s neck, looking for a pair of motorogy blood vessels with a diameter of only about 1 mm, extending to the transplantation fibula and fibula blood vessels, which was very difficult to operate.

After hard work, the operation was finally completed after 9 hours.

According to reports, the operation changed the concept of traditional mandibular tumor resection and reconstruction, creatively combining endoscopic technology with the reinforcement of the mandible, realizing minimally invasive, less bleeding, and low risk of infection. Patient’s postoperative recovery time -patients can be discharged 5 days after surgery, and there are basically no surgical scars on the face. After the wound is fully recovered, tooth planting will be performed on the transplanted double -layer fibula flap to restore Ms. Xing’s chewing function.
