He had brain bleeding and now (years later) still can not smell or taste. is there a surgery that can make that comeback?

Probably not: Although this is really a question for a neurologist, my thoughts are that if you do not have any nasal obstruction or major nasal congestion, the hemorrhage in the brain may have destroyed the olfactory nerve, the nerve of smell in the frontal lobe base. If this is the case, then it is unlikely that anything can be done to restore this function. Lack of smell is accompanied by lack of taste.

No usually: The persistent symptoms may be irreversible, and unless there are co-morbidities in sinus or nasal areas, or medications which are contributing, this may be almost impossible to change. But, could try Zinc supplements for a few months, and may be of some value to have an otolaryngologist evaluate.
