If the ear mesh is pierced, how much is avoided on its own, and how much surgery is required

In the inner layer of the ear there is a mesh, through which we hear sound. If this lattice is torn or there is any problem in it, the hearing will be weak. But we don't care so much about something so sensitive. We are doing everything from waxing the ear to putting oil in the ear, which can cause a hole in the eardrum.
