① Foreign bodies in nasal cavity: it is more common in children, because foreign bodies cannot be discharged from nasal cavity and cannot be informed to adults in time. After a long time, foreign bodies remain in the nasal cavity, causing mucosal inflammation, mostly unilateral nasal congestion and purulent nasal discharge.

Some patients with bad smell will smell bad smell if they are far away from them, so they are called smelly nose disease.

① Purulent secretion of sinusitis often smells fishy; Especially odontogenic maxillary sinusitis, its secretion is often very unpleasant, and only the patient can smell it.
② Extranasal causes: such as nasopharyngeal lesions, tonsillitis, dyspepsia, stomach diseases, etc. Patients often think that there is something wrong with the nasal cavity because of the upward smell. This smell is rarely felt by others.

Originally, there was no abnormal smell in the nasal cavity, but the patient felt that the smell of the nasal cavity was particularly bad and urgently requested treatment. He often goes to see a doctor everywhere, and nothing unusual is found during the examination.
