Blockage of the ear canal may be related to cholesteatoma of the external auditory canal, cerumen embolism, acute diffuse otitis externa, etc. Depending on the cause of the disease and the characteristics of the disease, general treatment, medication and surgical treatment should be chosen.
1. Cholesteatoma of the external auditory canal: A blockage of the ear canal is formed when a mass of exfoliated epithelium containing cholesterol crystals obstructs the bone of the external auditory canal. Surgery is needed to remove the cholesteatoma while controlling the infection with antibiotics such as amoxicillin and cefixime.
2. Cerumen embolism: Under the effect of excessive secretion of cerumen from the external auditory canal and poor drainage, cerumen accumulates and becomes an embolism, blocking the external auditory canal. The cerumen can be removed under direct vision or the earwax can be softened by sufficient infiltration with sodium bicarbonate ear drops, and then flushed out with saline to restore the ear canal.
3. Acute diffuse otitis externa: swelling of the external auditory canal due to trauma, infection and allergy can block the ear. Antibiotics such as amoxicillin can be applied systemically to control the infection. When the external auditory canal is red and swollen, a tampon soaked with 10% ichthyol glycerin can be applied locally. If the external auditory canal is swollen and oozing, a tampon soaked with 5% aluminum acetate can be applied to the external auditory canal.
When the blockage of the ear canal occurs, you can actively seek medical treatment, systematic examination, after a clear diagnosis, follow the doctor’s instructions to standardize the treatment.
