Several common clinical examinations of nasopharyngeal carcinoma

In order to detect nasopharyngeal cancer in time, in addition to understanding the symptoms of nasopharyngeal cancer, it is also necessary to check nasopharyngeal cancer in time, so as to better diagnose nasopharyngeal cancer. What are the common methods for checking nasopharyngeal cancer? The following will tell you about the common methods for checking nasopharyngeal cancer.

Generally, the common methods for examining nasopharyngeal cancer are:

1. Anterior rhinoscopy: After the nasal mucosa is retracted, the posterior nostril and nasopharynx can be seen through the anterior rhinoscopy, and tumors that have invaded or are adjacent to the nostrils can be found. This is a common method for examining nasopharyngeal cancer.

2. Indirect nasopharyngeal endoscopy: This method of examining nasopharyngeal carcinoma is simple and practical. Each wall 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.

3. 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 on the surface, and 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 examining nasopharyngeal carcinoma 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.

4. Neck biopsy: For cases that have not been diagnosed by nasopharyngeal biopsy, neck mass biopsy can be performed. 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 indeed 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. This is also a common method for examining nasopharyngeal carcinoma.

The above is an introduction to the common methods of checking nasopharyngeal cancer. I believe everyone has some understanding of this. For more questions about checking nasopharyngeal cancer, you can consult our online experts, who will answer them in detail.
