Injuries can occur to the thin skin lining of the ear canal; often caused by an ear syringe tip, cotton bud, match-stick, bobby-pin or tree branch.
Any ear canal wound should be inspected under a microscope. If the edges of a skin tear are laid back into position, healing is fast and the skin layer heals to cover the underlying skull bone entirely.
If the skull bone stays exposed it will slowly dissolve, creating an ulcer like defect, which will require regular cleaning under the microscope.
An open wound is always more prone to infection. Ear canal wounds must be kept dry until healed – see our how to How to Keep Your Ears Dry page
