Nasal endoscopy for nasopharyngeal carcinoma

As the weather gets hotter, it is not difficult to find that nasopharyngeal cancer has become a common disease, but many nasopharyngeal cancer patients are not aware of it, which makes the treatment of nasopharyngeal cancer more difficult. So, what examinations should nasopharyngeal cancer patients do? Let's answer it together below.

1. Anterior rhinoscopy: After the nasal mucosa is contracted, the posterior nasal cavity and nasopharynx can be viewed through the anterior rhinoscopy, and tumors that have invaded or are adjacent to the nostrils can be detected.

2. Indirect nasopharyngeal endoscopy: The method 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 asymmetrical submucosal protrusions or isolated nodules on both sides should be paid more 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 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 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 information helps us understand the relevant knowledge of nasopharyngeal carcinoma. We should pay more attention to the prevention of nasopharyngeal carcinoma in our daily life and treat nasopharyngeal carcinoma as soon as possible. Through the above introduction, everyone should have some understanding of what examinations nasopharyngeal carcinoma patients should do.
