When a worm is suspected to be inside the ear, the patient will have a feeling of crawling, prickling or painful worms in the ear canal in the early stage. Once the worms are locally necrotic, it may lead to inflammation in the ear canal and risks associated with pus flowing from the ear canal, ear canal pain, hearing loss, tympanic membrane perforation, etc. If a patient suspects that a worm has entered the ear canal, it is recommended that the patient go to an ENT clinic and have an otoscope done by a professional doctor to examine the ear canal to see if the worm can be seen, and if no worm is seen or if the worm is relatively small, it is clinically recommended that an electronic tympanic membrane image examination be done. This examination allows a clear view of the ear canal and the surface of the tympanic membrane to see if there are worms. If there are worms, the doctor can remove them endoscopically and observe whether there is perforation of the tympanic membrane, any ear infection, damage bleeding and other manifestations. After the worms are removed, local anti-inflammatory treatment of the ear canal is needed to avoid infection.
