There are several common causes of turbinate enlargement: i. The most common clinical condition is chronic simple rhinitis with bilateral inferior turbinate congestion and enlargement. It is recommended to use vasoconstrictive drugs, such as Daphnin spray nose. Second, allergic rhinitis stimulation, resulting in bilateral inferior turbinate enlargement. During the examination, the bilateral inferior turbinates are pale and there is clear water-like discharge in the nasal cavity. For treatment, use nasal spray hormone, such as endosolvadex or reno-cort spray nose. Third, less common is hypertrophic rhinitis, which leads to bilateral inferior turbinate hypertrophy. When examined, the bilateral inferior turbinates are congested and the surface is mulberry-like and uneven. There is no special medication to treat it, but if the symptoms are serious, surgery can be performed later. If unilateral inferior turbinate is abnormally enlarged, it is necessary to determine whether it is caused by nasal tumor and then treat it symptomatically.
