Why is there no sense of smell after nose surgery?
Your situation is not very good to judge the overall situation. If your nose is ventilated, you will have a sense of smell. Except the common cause-rhinitis accident. Rhinitis is just one of many reasons. There are three reasons for the bad sense of smell: (1) the smell can't reach the mucosa in the olfactory area: many people will have this experience. When a bad cold causes a stuffy nose, they lose their sense of smell. In fact, at this time, the function of olfactory nerve itself is still normal, but because of the blocked nose, air can not enter the olfactory area, and substances in the air can not be dissolved in the mucosal secretions of the olfactory area, and no chemical changes have taken place. Of course, it can't stimulate olfactory nerve endings. In addition to a bad cold, when severe nasal congestion is caused by sinusitis, chronic hypertrophic rhinitis, nasal polyps, deviated nasal septum, nasal cancer, etc. , can cause a sense of smell loss. ⑵ Anomalous olfactory nerves that feel the smell itself: Some people will have this experience. When catching a cold, the sense of smell is reduced due to nasal congestion, but the cold has healed and the sense of smell has not recovered. In fact, this is because when you catch a cold, the cold virus has spread to the olfactory nerve, causing inflammation of the olfactory nerve, losing its normal function and not feeling the smell. In addition, there are some cases where the sense of smell is paralyzed due to inhalation of irritating gases such as acetylene or diluent, or the sense of smell is often caused by aging and functional decline of the body. ⑶ There are obstacles in the cranial nerves that receive odor information: the reason is brain injury, tumor, or mental illness. If the olfactory region is blocked and the sense of smell is lost due to cold, nasal polyps, chronic rhinitis, turbinate hypertrophy, nasal tumor and other reasons, as long as the cold is cured, polyps or tumors are removed, the nasal mucosa is contracted, and the nasal respiratory passage is unblocked, the sense of smell can be restored. However, if the olfactory nerve has been infected and inflamed by virus, the olfactory nerve function must be treated together with other primary diseases. You can spray or take drugs that are helpful to the nerves, such as steroids or vitamins that can promote nerve function. Generally, as long as it is treated in time, the sense of smell can be completely or partially restored. It should be noted that no matter whether the olfactory nerve endings or olfactory nerve centers are damaged, olfactory nerve cells will sometimes atrophy and never recover their sensory function if they are not paid attention to for a long time. Therefore, once you find abnormal sense of smell, you must treat it as soon as possible.
