Patients who cannot smell and do not have air in their nose often consider that there are new organisms forming in their nasal cavity. For example, polyps or papillomas, or even fibrovascular tumors, or malignant masses in the nasal cavity can cause nasal aneurysm and odor. It is recommended that patients go to the hospital for a detailed examination to clarify the specific situation inside the nasal cavity, either by anterior rhinoscopy or nasal CT. if it is a deviated nasal septum, it can often be corrected by surgery. If a nasal polyp, papilloma or malignant mass is considered, pathology can often be taken to clarify the diagnosis before further surgery and, if necessary, radiotherapy. If the patient’s nasal cavity is considered to be formed by hemangioma, pathology cannot be taken to avoid hemorrhage, and vascular embolization is often required before removing the mass. After active treatment, the patient’s nasal incompetence and inability to smell will improve.
