An ear that is plugged with earwax is called a cerumen plug and can be removed by applying earwax dissolvers, flushing and manual removal. 1. Earwax dissolvers: These are mainly sodium bicarbonate ear drops that soften hardened cerumen to make it easier to remove from the ear. Suitable for those without a history of ear infections, perforated eardrums or ear surgery. 2. Irrigation: Irrigation of the ear canal with a syringe with a catheter and sterile saline or diluted hydrogen peroxide under the supervision of a physician is the most effective and safe method to quickly and significantly alleviate the discomfort, hearing loss and other symptoms caused by cerumen. 3. Manual removal: Cerumen is removed under direct visualization otoscopy using cerumen hooks, forceps, etc. under the supervision of a doctor. This method is preferred for patients with the presence of intra-auricular infections, tympanic membrane perforation, or immunodeficiency. Patients who have earwax in their ears are advised to visit an ENT department for consultation and treatment.
