The prosthetics function in one of two ways depending on where they’re required. Models of fingers, hands and toes are placed via suction, however, for more complicated areas like ears, where there’s nothing for it to attach to, it’s placed on with medical glue that lasts seven days and is shower proof. Fingers and toes start at £520, noses or ears are priced around £1000 but the investment can be life changing for patients.
