Cerumen mass is the yellowish secretion secreted by cerumen glands. Patients can go to regular hospitals to have cerumen removed by cerumen hook removal method, external auditory canal flushing method and suction method under the operation of doctors. 1. Cerumen Hook Removal Method: For the movable cerumen that has not completely blocked the external ear canal, cerumen hooks can be used to remove cerumen masses under the operation of doctors. 2. External ear canal flushing method: For patients with hard and dry cerumen that is difficult to remove, 5% sodium bicarbonate solution can be dripped into the ear first, and after the cerumen is softened, the external ear canal can be flushed with physiological saline to remove the cerumen. 3. Suction method: After the application of drugs to soften the cerumen, especially for patients with narrow external auditory canal, the cerumen can be removed by negative pressure suction under endoscopy. Patients are advised to keep the external auditory canal clean in daily life, not to dig the ear with hard objects by themselves, and to go to professional medical institutions for cleaning if necessary.
