Most of the age of onset is middle-aged, and there are also adolescents. The etiology and ethnic susceptibility (yellow species are more likely than Caucasians), genetic factors and EB virus infection, etc., the degree of malignancy of nasopharyngeal carcinoma is higher, cervical lymph node metastasis can occur in the early stage. The best treatment time: general surgery is recommended to be treated after the initial diagnosis of the disease, so that early detection and early treatment, special surgery should follow the doctor's advice. Treatment of diseases: nasopharyngeal carcinoma Indication Nasal cancer after radiotherapy treatment of the primary lesion retraction, there are residual, or cancer recurrence, not suitable for re-radiation, cancer is more limited, no skull base bone destruction or cranial nerve damage, no distant metastasis, general condition Better. The treatment of nasopharyngeal carcinoma is still the first choice for radiotherapy, and the effect is better. Surgery is preferred, and surgery alone is not advisable. Contraindications 1, there is skull base bone destruction or paranasal infiltration, cranial nerve damage or distant metastasis. 2, there are liver and kidney dysfunction, poor overall condition. Preoperative preparation Routine for the skull base x-ray or ct, to understand whether there is bone destruction, so that when the operation is "in mind." Surgical procedure 1, through the oral hard fistula approach, using the same method as fibroangioma resection, after entering the nasopharyngeal cavity, exposed tumor tissue, a mucosal incision at the safe margin around the tumor. 2, the tumor is located in the upper part of the posterior wall of the nasopharynx, close to the bone surface separation, located in the lower part of the posterior wall of the nasopharynx, separated along the anterior fascia, located in the nasopharyngeal wall, must include the tumor and nasopharyngeal wall The eustachian tube bulge is removed together. The curette can be used more during the operation to make the tumor clearer. After the tumor was resected, the base was electrocauterized, and the anterior and posterior nostrils were used to stop bleeding and suture the ankle incision. complication Incision delayed healing and wound infection.
