An example in which a patient was referred to a psychiatrist by the otolaryngologist for olfactory reference syndrome. The case actually had a strong nasal smell. I name the following condition as nasal secretion deficiency syndrome. This is a new concept of ozena. No abnormalities were found on computed tomography (CT) and magnetic resonance imaging (MRI) , but only a rough nasal mucosa was observed with endoscope. If look over the Internet, many people suffer from similar condition. Almost all complain of an abnormally dry nose. Although the frequency of this disease is high, it has been diagnosed as olfactory reference syndrome. There was no crusting and atrophy of nasal cavity, and only nasal mucosa was found to be degraded by an endoscope. Because it was hidden by a veil of atrophic rhinitis and ozena, it was overlooked and now overlooking conditions. It can be said that all women at least have olfactory reference syndrome. The excretion of bacteria stays on the nasal mucosa, and emits a bad smell. It is mainly caused by chronic rhinosinusitis, but may also be caused by other causes. Many people say that it gets worse during the cold and dry season. The underlying cause of this condition is lack of secretion of runny nose. The devastation of the nasal mucosa of nasal cavity, goblet cells that produce nasal secretions are damaged, the organization of nasal secretions is strongly reduced.
