(1) anterior nasal endoscopy
The nasal mucosa after convergence of anterior nostril mirror can glimpse into the choana and nasopharynx can be found in or adjacent to the nostrils of cancer invasion.
    (2) indirect nasopharynxscopes
Method is simple and practical, in order to check the nasopharynx of the wall, pay attention to nasopharyngeal top and posterior wall and on both sides of the pharyngeal recess to both sides of the corresponding parts were observed, where the asymmetry of submucosal uplift or solitary nodule should attention.
    (3) Nasopharygo fiberscope
Nasopharygo fiberscope, first with 1% ephedrine solution convergence of the nasal mucosa, nasal meatus dilatation, using 1% dicaine solution surface anesthesia nasal meatus, then the fiberscope inserted from the nasal cavity, while observing a forward until the nasopharyngeal cavity. The method is simple and convenient, and the mirror is fixed, but the posterior nasal cavity and the anterior wall of the anterior wall are not satisfied.
    (4) neck biopsy
For patients with nasopharyngeal biopsy that have not been diagnosed, a biopsy of the neck mass can be performed. General can be done under local anesthesia, patients should choose the earliest hard lymph node, even for the envelope extraction. Excision biopsy is indeed difficult, in a mass for wedge excision and biopsy tissue cutting and must have a certain depth and avoid extrusion, postoperative surgical field should not be as tight suture.
    (5) fine needle aspiration
This is a simple and convenient, safe and efficient tumor diagnosis method, in recent years is pushing the calamity, cervical lymph node metastasis of doubt, first to use fine needle biopsy cells. Specific methods are as follows:
1. Nasopharyngeal neoplasm puncture: No. 7 long needle pick on the syringe, oropharyngeal anesthesia in indirect nasopharyngoscope will prick of the needle into the tumor parenchyma and injection syringe to negative pressure within the tumor round-trip twice, will pull out the extract coated on a slide cytology.
2. Neck masses by fine needle aspiration: 7 or 9 needle connected to 10ml syringe, local skin disinfection, select the puncture point along the long axis of the tumor into needle syringe suction, which causes the needle in the tumour round-trip activity 2 ~ 3 times, after the removal of the aspirates do cytology or pathology examination.
    (6) serological detection of EB virus
At present, it is widely used to detect the VCA / IgA and IgA/EA antibody titers of EB virus by the method of enzyme immunoassay, the former is relatively high and the accuracy is low, and the latter is just the opposite. Therefore, the detection of two kinds of antibodies to the suspected and nasopharyngeal carcinoma should be carried out at the same time, which is helpful for the early diagnosis. The cases of IgA / VCA titers greater than or equal to 1:40 and / or IgA / EA titers greater than or equal to 1:5, even if there is no abnormality in the nasopharynx should also be in nasopharyngeal carcinoma (NPC) good hair place take exfoliated cells or biopsy. If the time has not yet confirmed, should be regularly followed up, if necessary, to make a number of biopsy.
    (7) lateral cranial base slice and CT examination
Each patient should be routinely used as a nasopharyngeal lateral and skull base photos, suspected and other parts of the middle ear or other parts of the nose, should also be taken as appropriate. Conditional units should be used for CT scanning, understanding of local expansion, in particular, the need to grasp the scope of infiltration of the pharynx, this is very important for determining the clinical stage and the development of treatment programs are extremely important.
    (8) B type ultrasonic examination
B type ultrasonography in the diagnosis and treatment of nasopharyngeal carcinoma (NPC) has been widely applied, method is simple, nondestructive injury, patients are willing to accept, in nasopharyngeal carcinoma (NPC) is mainly used for liver neck peritoneal and pelvic lymph node checks to see there is no liver metastasis and lymph node density cystic.
    (9) magnetic resonance imaging examination
Due to the magnetic resonance image (MRL) can clearly show the head at all levels of the cerebral sulcus gyrus gray matter white matter and ventricular cerebrospinal fluid conduit vessels and Se showed t1t2 prolonged high intensity images, the diagnosis of nasopharyngeal carcinoma of maxillary sinus carcinoma, and show the relationship between the tumor and the surrounding tissue.
