The child, 11 years old, was admitted to the hospital on May 12, 2012, mainly because of a right parotid mass 1 month after surgery. The child was admitted to the local hospital 2 years ago with a painful swelling in the right parotid gland area because of a painless mass in the right parotid gland for 2 years and the swelling disappeared after anti-infection treatment, but a peanut-sized mass remained in the parotid area. It grew progressively, and 1 month ago, the mass was examined at a local hospital, and the mass was about 2×3 cm, which was surgically removed. The wound healed well, and the lymph nodes in the right mandibular angle were enlarged and tough. The diagnosis of mucinous epidermoid carcinoma of the right parotid gland was confirmed after consultation of pathological sections. An enlarged resection was proposed for admission. No contraindications to surgery were found after routine examination. Yesterday, an enlarged resection of the right parotid tumor + facial nerve dissection was performed under general anesthesia. The surgical incision was “S” shaped, longitudinally following the right ear screen down around the earlobe and continuing with the previous incision, and the original incision was extended down to 2 cm below the angle of the mandible. The skin, subcutaneous tissue and cervical muscle were incised. The parotid gland was separated along the superficial surface of the parotid envelope and the surface flap was lifted. The parotid gland is then separated from the cartilage of the external auditory canal along the upper posterior part of the parotid gland to the deep side to find the common trunk of the facial nerve. The branches were separated along the common trunk of the facial nerve. Intraoperatively, the scar of the previous surgery was shown to have encircled the cervical facial trunk of the facial nerve. After separation, the facial nerve and its branches were completely dissected out. The deep lobe of the parotid gland is excised after freeing the facial nerve. The right mandibular angle lymph node was preferably treated, and it was found to be located under the posterior ventral part of the diastasis muscle with clear borders, two of them, the largest being about the size of a thumb. It was excised. The wound was irrigated and hemostasis was achieved. A negative pressure drainage tube was placed. Interrupted sutures were placed in layers. The operation was completed. On May 14, 2012, the first day after surgery, the patient was in good spirits. He could get out of bed. The right facial nerve was weakened, and 10 ml of exudate from the wound was drained by negative pressure drainage. It was proposed to change the medication in the afternoon, remove the negative pressure drainage tube and apply pressure bandage.
