What to do if the sense of smell fails? What should I do if my sense of smell fails?

Olfactory dysfunction may be caused by the following reasons: a tumor in the brain compresses the olfactory nerve, at this time, the brain can be taken MRI or brain CT to check whether there is a tumor, and if there is a tumor, surgery is required**. In addition, loss of smell can occur in the nasal olfactory area with tumors or nasal polyps, if there are nasal polyps or tumors in the olfactory area, we perform surgery to remove the tumor, which may restore part of the sense of smell.

It may also be due to a cold or acute inflammation of the nasal cavity, chronic inflammation caused by olfactory neuritis, causing loss of smell or reduction, you can use nasal spray hormone spray, Chinese patent medicine Tongjiao rhinitis granules oral, in addition to the use of nutritional nerve medicine for symptoms, comprehensive**, may alleviate the loss of smell. However, loss of smell is a disease that is difficult to treat, and sometimes it can be partially relieved, and sometimes the effect is poor and cannot be alleviated.

Olfactory dysfunction is a decrease in the sense of smell, or even a complete loss of the sense of smell, depending on what causes the loss of smell. Some of them are due to the decline of smell after a cold, that is, due to cold virus infection, some are due to the decline of smell after head trauma, and some are due to the decline of smell caused by allergic rhinitis and sinusitis for a long time. In this case, different measures should be taken for different reasons, so as to improve the loss of smell.

Usually, the loss of smell caused by cold virus infection, after the cold is cured, if it has not slowly recovered on its own, it is possible to consider using certain hormone drugs, including nasal spray hormone and oral hormones. Generally speaking, if the sense of smell is lost for a short time, it can be recovered slowly. Because rhinitis and sinusitis have been going on for a long time, resulting in a decrease in the sense of smell, it is necessary to take appropriate measures for rhinitis and sinusitis, such as anti-allergies**, which have a certain effect on the loss of smell.

The phenomenon of olfactory dysfunction is generally caused by damage to the olfactory nerve, which is very differentiated, so it is difficult to recover if it is not damaged in time. Under normal circumstances, the optimal recovery period of the nerves has passed after more than half a year, and the effect of ** will be greatly reduced.

Symptoms of olfactory dysfunction may be a decrease in the sense of smell or a complete loss of the sense of smell.

The sense of smell is produced by sensing odor through the mucosal nerve endings in the olfactory area of the nasal cavity and then conducting it to the brain through the olfactory nerve.

Common situations include acute rhinitis, chronic rhinitis, allergic rhinitis and chronic sinusitis, which lead to swelling of the nasal mucosa, as well as various benign and malignant new organisms such as nasal polyps, which make the patient have obvious nasal congestion symptoms, and also make it difficult for the smell to reach the mucosa located in the upper part of the nasal cavity. In some patients, the olfactory nerve is invaded and damaged or even necrotic due to upper respiratory tract infection, which will also cause loss or even loss of sense of smell. At the same time, the patient also needs to have the brain examined accordingly to rule out mass lesions in the brain, especially in the olfactory area.

Olfactory dysfunction is a decreased sense of smell or a disturbance of the sense of smell. There are many reasons for the loss of smell, and the more common causes are related to viral infections, such as cold virus infection, some people will have loss of smell and decreased sense of smell after a cold and fever, which is usually considered to be related to cold virus infection.

In addition, the loss of smell may be related to rhinitis sinusitis, allergic rhinitis and sinusitis for a long time, and the sense of smell will decline to a certain extent. One of the causes is related to the swelling of the nasal mucosa or the formation of nasal polyps, which causes blockages. In addition, rhinitis itself also causes certain damage to the olfactory nerve function in the olfactory area, resulting in a decrease in the sense of smell.

Head trauma can also cause some degree of loss of smell, as well as genetically related loss of smell.

For olfactory failure, appropriate nasal endoscopy can be carried out, as well as olfactory examination, as well as olfactory nerve magnetic resonance examination to further clarify the diagnosis, according to the degree and cause of olfactory decline, take different methods, appropriate ** to strive to improve olfactory function, usually drugs ** including nasal spray hormone and oral hormone **, generally for some patients can achieve better results.

Olfactory dyssis can be diagnosed by nasal endoscopy, olfactory examination, and olfactory nerve magnetic resonance scanning, and different drugs**, including nasal spray hormones and oral hormones**, depending on the degree and cause of the anosmia.

According to the data analysis, olfactory failure is a difficult disease of the nervous system, and there is no better way to treat olfactory failure under current medical conditions.

If the sense of smell fails, you should first go to the hospital for a specialist examination as soon as possible to check whether there is a obstructive disease in the nasal cavity. If there is no improvement or further loss of sense of smell over time** and observation, further investigations, including sinus CT, should be done to rule out other possible causes, such as sinusitis, early nasal polyps, olfactory nerve tumors, and then according to **. The olfactory epithelium has the potential for differentiation and regeneration, and the onset time is generally short, as long as the nasal blockage is solved, the damaged epithelial cells can be gradually repaired over time, and the sense of smell can also be improved.

With a long onset of disease, the damage to the olfactory epithelium tends to become irreversible, and even if the nasal cavity is unblocked, different odors cannot be felt.
