Thanks for the query. Indeed, there can be many long term complications given your trauma: increased risk of seizures, headaches
, memory impairment and mood disturbances. You had extensive neurologic damage of the cranial nerves, and only time, healing and adequate therapy will be able to tell how much of each cranial nerve, involved in facial movement, hearing, swallowing, speech and movement of the neck, you will recover.
Hope that helps, wish you the best,
