Yes. It has been scientifically documented that ears get longer with age, but never wider because of gravity. Ears grow an average of 0.22mm a year in length. It occurs in both men and women.

Yes, it's true, but the answer is interesting, as they are not really growing, they just appear to be larger. The answer is still a mystery, as nobody really knows if they grow, or are they getting "droopier" because of the gravitational pull. It's likely the latter, and ears do appear to grow .22 mm a year according to the source below, yet the reality is they are not really growing.

Although, scientific studies have shown to attempt to answer this challenging question. A project found that on average, ears grow one-hundredth of an inch every year. Many people believe since our ears and nose are made of cartilage is the reason why our ears grow after our bones have stopped growing. The experts at the MadSci network have said it's simply not true for humans and other animals with a bone skeleton.

So why are ears on the elderly larger? Some believe that large ears somehow correlate with longer life.

Plastic surgery sites have read, "Nasal cartilage becomes thinner and loses its elasticity as we age, causing the tip of the nose to lengthen and droop." Maybe our nose and ears just get droopier.

So watching out for bias, I thought about ear and nose growth. Are they different from the rest of the body? Probably not – the outer or external ear is mostly cartilage and skin, with a little fat and muscle and a supply of blood vessels and nerves. Does cartilage and skin continue to grow throughout life? Yes and no. The cells continue to divide, grow, mature and die, just like cells in the gut, liver, bones and elsewhere. And the amount of skin and cartilage in our bodies obviously increases as we grow. But cartilage does not keep growing at the same rate throughout life, and while cartilage keeps dying and being replaced, in the vertebrates it does stop increasing in size in adulthood – which is what is usually meant by ‘keeps growing’. This information can be found in most introductory physiology text books.

The size of the ear canal does not increase with age. The ear canal is defined by skin and cartilage as well as bone. That suggests that there is no overall ear cartilage growth in adulthood.

To prevent this "ear growth," there are probably some cosmetic procedures or vitamins that tighten the elasticity in your skin, yet nothing is a guarantee.
