Fiber mirror seems to be more advanced than indirect mirror. Is it possible that the fiberscope can see what the indirect mirror can't? It is possible to regard the sputum lump in the nasopharynx as a translucent lump. Translucent masses in the nasopharynx can only be cysts, not nasopharyngeal carcinoma. The picture you uploaded is not clear, so you can only reply like this.

(Dr. Lin Weinian solemnly reminds me that because I can't see the patient face to face, I can't fully understand the condition. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
