Why does the myth that prevalent that ear surgery is not successful, exist?

In this video, Dr. Nishi Gupta, Head department of ENT, Dr. Shroffs Charity Eye Hospital, Delhi, will bust the myth which is prevalent that ear surgery is not successful. she will explain why it is so, for example if it is clear case of perforation then by just putting a graft is also sufficient but if the bones of the ears are damaged then the patients are explained about the condition. Through the otoscope, just a small dimple is seen but the disease is spread inside. Hence, drilling the bone cavity is required and then the graft is placed.
