It is recommended that the patient actively go to the ENT department of the hospital to check and confirm the diagnosis, it is best to improve the nasopharyngoscopy and coronal CT of the nose, and after the diagnosis is confirmed, the patient’s symptoms should be significantly improved, and further detailed examination if necessary.
