When a patient has a fungal infection in the ear canal, there are a variety of medications that can be applied selectively. Common medication forms include creams, in-the-ear drops, and some in-the-ear sprays and so on. If the location of the fungal infection in the ear is relatively superficial, you can apply some localized ointment such as meconium to the ear canal, which can have a better effect of killing and inhibiting the fungal infection. If the location of the fungal infection in the ear canal is relatively deep, salicylic acid alcohol ear drops can be used for treatment and control, and some in-ear sprays can also be used selectively. At the same time of medication, patients should first try to do a good job of cleaning the ear canal. If there are more foci of mycobacterial infection in the ear canal, or if the entire surface of the eardrum is covered, attention should be paid to cleaning out these foci as thoroughly as possible in order to make the effect of medication better.
