Detailed explanation-1: -Otitis externa is a condition that causes inflammation (redness and swelling) of the external ear canal, which is the tube between the outer ear and eardrum. Otitis externa is often referred to as “swimmer’s ear” because repeated exposure to water can make the ear canal more vulnerable to inflammation.
Detailed explanation-2: -Bone and cartilage damage (necrotising otitis externa). Infection spreads to the skin and cartilage of the outer ear and bones of the lower part of the skull, causing increasingly severe pain.
Detailed explanation-3: -Otitis externa is most commonly caused by infection (usually bacterial, although occasionally fungal), but it may also be associated with a variety of noninfectious systemic or local dermatologic processes.
Detailed explanation-4: -Polymyxin B, neomycin, and hydrocortisone 3 to 4 drops to the affected ear four times a day. Ofloxacin 5 drops to the affected ear twice daily. Ciprofloxacin with hydrocortisone 3 drops to the affected ear twice daily. 12-Feb-2023
