'Small ears often mean small ear canals [the tube running from the outer to the middle ear], which gives you a greater chance of developing eczema of the ears,' says George Murty, consultant ear, nose and throat surgeon at University Hospitals Leicester.If you have small, very low-set ears, below the level of your eyes, it often indicates you have kidney problems. No one knows why, but you might lack one, have two fused together, or get kidney disease later in life,' says Mr Murty.
