When the patient seems to have earwax inside the ear and it appears to rattle when wiggled, attention needs to be paid to further detailed examination of the ear, and tools can be used to clean it if necessary. Patients may have some lumps of cerumen in the deeper part of the ear canal, which may be dislodged from the wall of the ear canal and can be shaken with head movement, which may further cause repeated friction or impact on the deeper eardrums, thus triggering the ringing symptom. Some patients may have some flaky cerumen tightly coated on the surface of the eardrum, which is difficult to be removed by themselves. In order to remove these cerumen clogs, tweezers or suction tools can be used to clean the cerumen, and if necessary, phenol-glycerin drops or sodium bicarbonate solution can be used to soften and dilute the cerumen before cleaning it, which will help to improve the symptoms.
