How to identify nasopharyngeal carcinoma? What are the symptoms?

The early diagnosis rate of nasopharyngeal carcinoma is not high, which may be related to the fact that patients' early symptoms are easy to ignore, patients' late treatment, hidden lesions, easy to miss detection, and rapid disease progression. Most diagnoses are late. Clinically, when middle-aged patients have clinical manifestations such as nasal respiration with blood, headache on one side of the pillow, swollen cervical lymph nodes, and effusion on one side of the middle ear, nasopharyngeal examinations should be performed repeatedly.

The typical symptom of three-quarters of nasopharyngeal carcinoma patients is bloody nasal discharge. Once nose bleeding is accompanied by simple nasal congestion, ear stuffiness, and foul-smelling nasal discharge, the possibility of malignancy should be considered. If there is a family history, and the symptoms of nasal congestion or nose bleeding continue to appear, we should be highly vigilant. Most people take a shower in the morning, which is a typical early manifestation of nasopharyngeal carcinoma.

The following examination methods can be used to identify nasopharyngeal carcinoma.

1 After the nasal mucosa is converged, the posterior nares and nasopharynx are examined through anterior rhinoscopy to detect cancer that has invaded or invaded the adjacent nostrils.

2 Indirect nasopharyngoscopy is simple and practical. Check the nasopharyngeal wall in turn, pay attention to the posterior wall of the nasopharyngeal roof and the pharyngeal recesses on both sides, and compare and observe the corresponding parts on both sides. Pay more attention to the asymmetric submucosal bulges or isolated nodules on both sides.

3 Fiberoptic nasopharyngoscopy Fiberoptic nasopharyngoscopy can first use 1% ephedrine solution to astringe the nasal mucosa and expand the nasal passages. Then use 1% dicaine solution to anesthetize the nasal passages, and then insert the fiberscope into the nasal cavity, observe while pushing forward until the nasopharyngeal cavity. This method is simple and the mirror is fixed, but the observation of the posterior nasal cavity and the anterior wall is not satisfactory.
