Prolonged hypertrophy of the nasal mucosa can lead to narrowing of the air in the nasal cavity, which can cause impaired ventilation and drainage of the nasal sinuses and can lead to sinusitis, especially purulent sinusitis. When the condition is particularly severe, symptoms such as headache, nausea and vomiting can occur. If the hypertrophy of the posterior end of the inferior turbinate is particularly significant, it will compress the pharyngeal opening of the Eustachian tube, thus causing dysfunction of the Eustachian tube, resulting in pressure changes in the middle ear and otitis media, leading to hearing loss, a feeling of stuffiness in the ear, tinnitus, and even symptoms of vertigo. If there is more secretion in the nasal cavity, it can go backward through the nasopharynx into the pharynx, resulting in postnasal drip syndrome and causing long-term chronic irritating dry cough. If the mucosal hypertrophy is caused by allergic factors, it can also cause allergic reactions in the respiratory tract and symptoms such as asthma.
