The difference between deviated nasal septum and nasopharyngeal carcinoma includes disease definition, etiology, clinical symptoms, treatment modalities and prognosis.
1. Definition: deviated nasal septum refers to the deviation of nasal septum to one or both sides, while nasopharyngeal carcinoma is a malignant tumor occurring in the anterior wall of nasopharyngeal roof and pharyngeal crypt.
2. Causes: Deviated nasal septum can be caused by dysplasia of the nasal septum, fracture of the nasal septum due to trauma, and compression of the nasal septum by nasal cavity occupation. Nasopharyngeal cancer is related to heredity, EBV infection, bad dietary habits and so on.
3. Clinical symptoms: deviated nasal septum mainly manifests as nasal congestion, nosebleed, headache, etc. Early stage of nasopharyngeal cancer may manifest as blood in nasal discharge, nasal congestion, etc., and headache, enlarged lymph nodes and other symptoms may also appear.
4. Treatment: Those who have no symptoms caused by deviated nasal septum may not have special treatment, and if necessary, surgery is feasible to correct it. Nasopharyngeal cancer is mostly low-differentiated squamous carcinoma, which is sensitive to radiotherapy, usually radiotherapy is the first choice, combined with chemotherapy and surgery.
5. Prognosis: Nasal septal deviation can usually be relieved and clinically cured after appropriate surgical correction. Nasopharyngeal cancer can improve survival through radiotherapy and chemotherapy, but the cure rate of advanced metastasis is lower.
The above are some of the differences between deviated septum and nasopharyngeal carcinoma, and the specific differential diagnosis should be carried out by professional doctors.
