What tests should patients with nasopharyngeal carcinoma undergo before treatment?

The incidence of nasopharyngeal carcinoma has been on the rise in China, so understanding the examination of nasopharyngeal carcinoma is very helpful for the treatment of patients. So what are the examination items for nasopharyngeal carcinoma ? Let the experts introduce the examination items for nasopharyngeal carcinoma to us in detail.

The main examinations for nasopharyngeal carcinoma include the following aspects:

1. 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. The surgical field should not be sutured too tightly or too densely at the end of the operation.

2. 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.

3. 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 asymmetric submucosal protrusions or isolated nodules on both sides should be paid more attention.

4. 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.

The above is a detailed introduction of the experts on the examination of nasopharyngeal carcinoma. I hope it will be helpful to you. Experts remind patients that once diagnosed, they should go to a regular hospital for treatment in time to avoid worsening of the disease.
