Our expert says:
It is possible that your husband suffered damage to the anterior skull base during his fall. The treating doctor should know the extent of the injury. Unfortunately the nerve responsible for your sense of smell runs in the front part of the brain, and exits the skull base via the cribiform plate (the thin bone that seperates your brain from your nose). These nerve fibres are very thin, and are easily damaged by head injuries. If the nerve fibres were only streched, they may recover over time, but if they were torn, the damage is permanent. Your sense of taste relies on your ablilty to smell, so if you loose smell, this will affect your ability to taste. There may also have been damage to the nerve for taste, but a neurologist must diagnose this.
To get an indication of the extent, your husband may benefit from a neurological examination, performed by a neurologist, to get an idea as to the nature of the damage. It seems unlikely that there will be much more improvement, as the head injury seems to have been rather severe.
