Earwax that is black is considered to be related to cerumen impaction, external ear canal injury, fungal otitis externa and other causes.
1. Cerumen impaction: Due to long time not cleaning earwax or strong cerumen secretion, excessive earwax may accumulate in the ear canal for a long time, which will make the cerumen darker in color. Therefore, the clinical symptom of black earwax may appear in the case of cerumen impaction. Regular cleaning of cerumen can effectively prevent the occurrence of the above symptoms.
2. Injury to the external auditory canal: Earwax pulling, external blows and other factors can lead to bleeding caused by injury to the external auditory canal. Bleeding around the wound can coagulate and form black blood crust after drying gradually, which can also lead to the clinical symptom of black earwax.
3. Fungal otitis externa: Decreased immunity, long-term abuse of antibiotics and other factors can increase the incidence of fungal otitis externa. Part of the secretion formed by the fungal infection is black in color, which can also trigger the symptom that the earwax is black. Itchy ears, blocked ears, dampness and pain in the external ear canals may also occur during the disease.
When these symptoms occur, it is necessary to consult an ENT doctor to determine the cause of the disease and then follow the doctor’s instructions for treatment.
