Commonly used examination methods for nasopharyngeal carcinoma

What are the common examination methods for nasopharyngeal cancer? There are many common symptoms in life, such as: nasal congestion, dizziness, lack of concentration, etc., which are either caused by colds or rhinitis. Most people think so, but you must not ignore the disease of nasopharyngeal cancer. It is very harmful and needs timely treatment after being sick. Let's learn about the common examination methods for nasopharyngeal cancer.

1. Fiber nasopharyngeal endoscopy.

Fiberoptic nasopharyngoscopy is one of the methods for examining nasopharyngeal carcinoma. During this examination, 1% ephedrine solution is usually used to astringe the nasal mucosa to achieve the purpose of nasal passage expansion, and then 1% dicaine solution is used to anesthetize the surface of the nasal passage. After these preparations, the fiberscope can be inserted through the nasal cavity, pushed forward to guide the position of the nasopharyngeal cavity, and then the cancer can be observed.

2. Neck biopsy.

In addition to fiberoptic nasopharyngeal endoscopy, neck biopsy can also be performed. This examination is usually used when nasopharyngeal biopsy does not work well. Neck biopsy is mainly a pathological biopsy of cancer cells in the neck. Under local anesthesia, the first lymph node and its entire capsule are removed. The importance of biopsy is self-evident. When performing tissue excision, you must pay attention to the depth of the cut and do not squeeze it.

3. Anterior rhinoscopy.

This examination method is to use a nasal endoscope to examine the nasal mucosa after it has contracted. This method can directly observe the patient's posterior nasal cavity and nasopharynx, and can also clearly detect tumor cells that have invaded the nostrils or near the nostrils.

4. Indirect nasopharyngeal endoscopy.

This examination method is quite simple and easy to perform. It can be used to diagnose the disease in the order of the walls of the nasopharynx, the posterior wall of the nasopharyngeal roof, and the pharyngeal recesses on both sides. When checking, it is necessary to pay attention to the corresponding examination of both sides. Once the bilateral mucosa is asymmetrical, and there are downward bulges and isolated nodules, the patient needs to pay enough attention.
