Olfactory failure may be related to deviated nasal septum, allergic rhinitis, chronic atrophic rhinitis and other diseases. Whether the disease can be cured after 5 years needs to be judged according to the cause of the disease, the characteristics of the disease, the treatment method and the timing of the treatment, and the efficacy of the treatment cannot be judged purely on the basis of the symptoms.
1. Nasal septum deviation: After the deviation of nasal septum bone and cartilage caused by various factors, the airflow can be hindered to reach the olfactory area, resulting in olfactory malfunction. If the olfactory reception and signaling pathways are normal, even if the sense of smell is lost for 5 years, it may be restored after surgical correction of the deformed structure.
2. Allergic rhinitis: after contacting or inhaling allergens in allergic patients, nasal allergic reaction may occur, and the resulting olfactory disorder may be accompanied by abnormalities of taste. When the history of the disease is long, and the olfactory spectrum shows some kind of “olfactory loss band”, it will be difficult to recover from olfactory malfunction after 5 years.
3. Chronic atrophic rhinitis: this disease can produce a lot of slugs and crusts blocking the olfactory region, and the olfactory region due to inflammatory factor stimulation of the mucous membrane, glandular atrophy, olfactory pigment can not be passed through the olfactory region mucus to stimulate the olfactory sense of the transmission of olfactory malfunction occurs. When this disease is up to 5 years old, irreversible inflammatory pathological changes are formed, and even after standardized systemic treatment, the chance of recovery of olfactory function is low.
The loss of sense of smell for 5 years may also be due to trauma, tumors, etc. It is necessary to actively consult a doctor for a systematic examination, to make a clear diagnosis, and to listen to the advice of the receiving physician for a comprehensive understanding of the disease information and prognosis.
