Nasal Pterygoid Duct Neurotomy may recur after surgery. Nasal Pterygoid Neurectomy is commonly used in the treatment of allergic rhinitis by removing the parasympathetic nerves in the nose to reduce the edema, congestion and inflammation of the nasal mucosa and improve the hypersecretion of the nasal mucosa. However, the allergens that induce allergic rhinitis still exist, and once exposed to the allergens, they may also cause inflammatory reactions in the nasal cavity. Therefore, recurrence is possible after nasolacrimal duct neurectomy. In case of recurrence after Nasal Pterygoid Neurectomy, it is recommended to go to the hospital as soon as possible for follow-up and take reasonable treatment plan in time with the professional doctor’s treatment advice. For the problem of nasal allergy, you should cooperate with the doctor to check the allergens, usually avoid contact with allergens, such as going out to wear a mask, don’t go to the pollen or dusty environment, don’t keep pets, so as not to induce allergic rhinitis.
