Can nasal endoscopy detect nasopharyngeal cancer?

With the continuous development of science and technology, the current medical level is also very advanced. Many diseases can be detected in the early stage. For example, nasopharyngeal cancer disease, although there are many steps in the examination, can accurately judge the condition. Can nasal endoscopy be used to examine nasopharyngeal cancer? Experts suggest that the following five steps are required to diagnose nasopharyngeal cancer.

1. Fiberoptic nasopharyngeal endoscopy

For fiberoptic nasopharyngoscopy, 1% ephedrine solution can be used to astringe the nasal mucosa and expand the nasal passages. Then 1% dicaine solution can be used to anesthetize the nasal passages. Then the fiberoptic scope can be inserted from the nasal cavity, and the scope can be pushed forward while being observed until it reaches the nasopharyngeal cavity. This method is simple and the scope is well fixed, but the observation of the posterior nasal cavity and the anterior wall of the roof is not satisfactory.

⒉ Anterior rhinoscopy

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

3. Neck biopsy

For cases that have not been diagnosed by nasopharyngeal biopsy, a neck mass biopsy can be performed. Generally, it can be performed under local anesthesia. During the operation, the first hard lymph node that appears 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. When removing tissue, a certain depth must be maintained, and squeezing should be avoided. At the end of the operation, the surgical field should not be sutured too tightly or too densely.

4. 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 observed in comparison. Any asymmetric submucosal protrusions or isolated nodules on both sides should be paid more attention.

Fine needle aspiration

This is a simple, safe and efficient method for tumor diagnosis, which has been highly recommended in recent years. For patients suspected of cervical lymph node metastasis, fine needle aspiration can be used to obtain cells first.

Patients with suspected cases of nasopharyngeal cancer should read this article carefully. To confirm the diagnosis of nasopharyngeal cancer, you need to do the five examination methods introduced by the above experts. I hope it can help those patients with nasopharyngeal cancer. Patients can choose the examination method that suits them according to their actual situation and the doctor's diagnosis. Early diagnosis can lead to early treatment.
