Experts explain important nasopharyngeal cancer examination methods

In addition to clinical symptoms, the examination of nasopharyngeal carcinoma in clinical practice also relies more on medical instruments to examine nasopharyngeal carcinoma, which is more beneficial to patients. What are the common examination methods for nasopharyngeal carcinoma ? The following will tell you about the common examination methods for nasopharyngeal carcinoma.

In general, the common examination methods for nasopharyngeal carcinoma are:

Fiberoptic nasopharyngoscopy: Fiberoptic nasopharyngoscopy can be performed by first using 1% ephedrine solution to contract the nasal mucosa and expand the nasal passages. Then, 1% dicaine solution is used to anesthetize the nasal passages. Then, the fiberscope is inserted from the nasal cavity, and the microscope is pushed forward while being observed until it reaches the nasopharyngeal cavity. This method of nasopharyngeal cancer examination is simple and the mirror is well fixed, but the observation of the posterior nasal cavity and the anterior wall of the roof is not satisfactory.

Anterior rhinoscopy: After the nasal mucosa is retracted, the posterior nostril and nasopharynx can be seen through the anterior rhinoscopy, and cancerous tumors that have invaded or are adjacent to the nostrils can be found. This is one of the common examination methods for nasopharyngeal carcinoma.

Nasopharyngeal endoscopy: This method is simple and practical. When examining nasopharyngeal carcinoma, the walls of the nasopharynx should be examined in turn, with attention paid to the posterior wall of the nasopharyngeal roof and the pharyngeal recesses on both sides. The corresponding parts on both sides should be compared and observed. Any asymmetric submucosal protrusions or isolated nodules on both sides should be paid special attention.

Neck biopsy: For cases that have not been diagnosed by nasopharyngeal biopsy, neck mass biopsy can be performed, which is also a common method of nasopharyngeal carcinoma examination. Generally, it can be performed under local anesthesia. During the operation, the earliest solid lymph node should be selected, and the capsule should be removed as a whole. If excisional biopsy is difficult, a wedge-shaped biopsy can be performed at the mass. The tissue must be cut to a certain depth and squeezed. At the end of the operation, the surgical field should not be sutured too tightly or too densely.

The above is a description of the common examination methods for nasopharyngeal cancer. I believe everyone has some understanding of this. Once diagnosed with nasopharyngeal cancer, you must go to the hospital for treatment immediately to avoid causing serious adverse effects on the patient's condition.
