1. What is cerumen embolism?
Cerumen embolism is a common cause of conductive hearing loss. Cerumen is usually expelled from the ear canal. Sometimes cerumen accumulates in the ear canal and forms a embolus, which can partially or completely block the ear canal. Cerumen suppository is brown and yellow. If the ear canal is wet, it will turn jujube red and black after drying (common in the elderly). If the ear canal is partially embolized, there will be no hearing loss. If the ear canal is completely blocked, there will be hearing loss. Don’t make a hearing test or choose a hearing aid before removing cerumen.
