What are the diagnostic methods for nasopharyngeal carcinoma?

Nasopharyngeal carcinoma is a common malignant tumor of the head and face. The early symptoms are not obvious. The diagnosis of nasopharyngeal carcinoma cannot be determined solely by its own symptoms. Laboratory and imaging examinations are the main basis for diagnosing nasopharyngeal carcinoma. The following is a brief introduction on how to diagnose nasopharyngeal carcinoma.

1. Anterior rhinoscopy: After the nasal mucosa is retracted, the posterior nasal cavity and nasopharynx can be viewed through the anterior rhinoscopy to detect cancer that has invaded or is adjacent to the nostril.

2. Indirect nasopharyngeal endoscopy: This method is simple and practical. Each wall of the nasopharynx should be examined in turn. Pay attention to the posterior wall of the nasopharyngeal roof and the pharyngeal recesses on both sides. The corresponding parts on both sides should be observed. Any asymmetrical submucosal protrusions or isolated nodules on both sides should be paid more attention. 3. Fiberoptic nasopharyngeal endoscopy: 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 where nasopharyngeal biopsy has failed to confirm the diagnosis, a neck mass biopsy can be performed.

5. Fine needle aspiration is a simple, safe and efficient method for tumor diagnosis. It 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. After removal, the aspirate can be subjected to cytological or pathological examination.

6. EB virus serological test: If the diagnosis is still not confirmed, regular follow-up should be performed, and multiple biopsy examinations should be performed if necessary.

7. Nasopharyngeal lateral film, skull base film and CT examination. Every patient should be routinely examined with nasopharyngeal lateral film and skull base film. If there is suspected invasion of the paranasal sinus, middle ear or other parts, corresponding radiographs should be taken at the same time. Units with conditions should perform CT scans to understand the local extension, especially the infiltration range of the parapharyngeal space, which is extremely important for determining the clinical stage and formulating treatment plans.

8. Type B ultrasound examination: Type B ultrasound examination has been widely used in the diagnosis and treatment of nasopharyngeal carcinoma. The method is simple, non-destructive, and is a commonly used method for nasopharyngeal carcinoma diagnosis.

9. Magnetic resonance imaging can diagnose nasopharyngeal carcinoma, frontal sinus cancer, etc., and show the relationship between the tumor and surrounding tissues.

The above is the diagnosis method of nasopharyngeal carcinoma introduced by experts. Expert Tips: If you have symptoms of disease, you can choose the appropriate treatment according to your symptoms, but do not delay diagnosis, and do not let your life be ruined by hesitation. You should go to a regular hospital for treatment in time to avoid delaying the disease and causing serious consequences.
