My condition seems to be more unique and difficult to recover from due to its cause. These articles don’t give me much hope but facts are facts. There is a slim chance that I might get my sense of smell back in months or years–that is if I am lucky enough..

 Recovery of olfactory function following closed head injury or infections of the upper respiratory tract
“During an observation period of approximately 1 year, more than 30% of patients with post-URTI olfactory loss experienced improvement, whereas only 10% of patients with posttraumatic olfactory loss experienced improvement. Furthermore, age plays a significant role in the recovery of olfactory function. ”
 

 Treatments for olfactory loss from Head trauma(HT)/ Post traumatic injuries:
“…the olfactory system has the ability to regenerate. Indeed, there is the potential for recovery after a head injury and animal studies have demonstrated that recovery is possible. Costanzo recorded cells from the olfactory bulb of a hamster and demonstrated recovery within nine months. However, in humans the prognosis is much lower and the estimated possibilities for recovery vary widely from 15% to 39%.” 

“It is generally believed that this aetiology can not be treated with drug therapy. However, approximately a third of sufferers do recover with the most likely cause being natural regeneration of the olfactory system. The onset of regeneration usually occurs within three months of the trauma ; beyond one year then the chances of recovery are slim. Early recovery may occur due to mechanisms such as the disappearance of blood clots, and later recovery, due to regeneration of neural elements. Complete recovery may take approximately five years.
