Hi. My name is Vinay. I m so sorry you ve had to live with such difficulty over the last year. Let me see if I can help you by starting with the basics and then working up to some actions that you can take that may be of help to you. Firstly since this injury is over a year old, I m going to assume your vision and general daily life has only been mildly affected by the loss of smell and taste. Secondly I m going to assume that you have no other major medical issues (things like Diabetes and Hypertension. It s ok if you do, its just that your sense of smell can actually deteriorate over time with diabetes). If i m wrong about that please let me know so we can explore those aspects. So.. That basics. Your senses of Smell and Taste are very closely interlinked. They travel along similar pathways and are processed by your brain in similar regions. It s unfortunate but its pretty common to lose your sense of taste (either partially or completely) when your sense of smell is injured. Now. i know you ve had a lot of scans and some of these questions may have already been answered.. but lets break your sense of smell down into two parts 1) Those smelly little particles (Bacon bits in the kitchen... freshly cut lawn particles) need to GET to the part of your nose that does the smelling (the roof of your nose, behind and a little below the bridge). So if air is not circulating well in there then your sense of smell can be affected. These kind of obstructive problems happen when your Nasal Septum (the slip of bone that divides your nose down the center) is damaged or deviated.. This can happen from trauma (hitting your nose) or you could have been born with a really badly deviated septum. The other Obstructive problem is overgrowth of the fleshy tissue inside your nose that moistens the air and filters all the dust out. This tissue is formed into 3 ridges on the inside of each nostril and they are called Turbinates . When these turbinates overgrow (allergy, infections, trauma.. just plain sucky luck) they can block the airflow to the smell receptors in the nose and cause your symptoms. These obstructive problems can be diagnose with scans like the ones you ve had before (CT s and MRI s). All you need to do is make sure that you and those scan have been seen by an Ear, Nose and Throat Doctor (ENT). Once the Obstructive problems have been ruled out and managed. Most of whats left involves damage to the nerve that carriers your sense of smell (Called the Olfactory Nerve). Unfortunately the treatment options for these kinds of problems are limited and you need to be evaluated by a neurologist to truly see whats wrong at that point. So is there hope? Of course! Always is! But lets try and find out whats causing the problem in the first place! I really hope this helps. If you have any questions.. Don t hesitate to ask. Thanks Vin
