Regarding the ear canal changing shape over time.
From an audiologist perspective, that really isn't an issue beyond the age of around 17-18 years old, as the bones/anatomy of the head is essentially fully developed by that age. That being said, 3/4 of the ear canal, is comprised of tissue, cartilage and fat.
If say an individual was to undergo a massive weight loss, or a massive weight gain, then yes, the ear canal in theory, could change in shape to some degree. I have only seen this happen twice in about 15 years, one of the individual had undergone a 100 lb weight loss.
