The ear can be disinfected with iodine volts, which is usually used for pre-operative disinfection during surgery, so there is no problem at all. Some ear infections or diseases may also require iodophor disinfection, such as the large ear cerumen in the ear, which can also be disinfected with iodophor after infection, and can be treated with antibiotic ointment or oral antibiotics for anti-inflammatory treatment. Sometimes auricular infections can also be disinfected with iodophor after the local infection is cleared, and alcohol can also be used for disinfection. However, if there is an obvious broken wound, disinfection with alcohol may cause stinging or pain, while iodophor stings less, so disinfection with iodophor is relatively more comfortable.
