Query: I’ve a particularly embarrassing downside. There’s a very unhealthy odour from the liner of my nostril. If I’ve a nasal drop it’s additionally unhealthy. I did see an ear/nostril specialist for one thing else and talked about it to him however he dismissed it and mentioned all the pieces was OK. That was about seven years in the past. It’s nonetheless the identical. I couldn’t probably be in very shut contact with somebody as I’m very acutely aware of it.
Dr Grant replies: It’s estimated that as much as 12pc of individuals over 40 years previous have a dysfunction with their sense of scent, often called olfactory dysfunction. Of the 12pc, about 3pc endure with anosmia which is an entire lack of their sense of scent, or extreme hyposmia (severely decreased sense of scent). For these victims, it clearly causes a diminished high quality of life with difficulties in figuring out the scent and infrequently flavour of meals, in addition to substances of their atmosphere that will additionally lead to well being and security hazards (eg gone off meals, one thing burning, potential fuel leak).
Following Covid-19 an infection (and another viral sicknesses) some folks nonetheless have a post-viral hyposmia, when the individual’s sense of scent by no means comes again to what it was beforehand.
There are a lot of different issues that may adversely have an effect on your sense of scent together with an infection or irritation inside the oral cavity, gum an infection (gingivitis) and dental cavities. Circumstances similar to rhinosinusitis or nasal polyp might adversely have an effect on scent in some folks.

Transferring on to your criticism. It seems that you’re struggling with parosmia which could be divided into varied subtypes similar to troposmia (a distorted sense of scent), phantosmia (detecting a scent when there may be none) or cacosmia (being unable to recognise or interpret completely different odours).
You’re most certainly struggling with cacosmia, as you assume there may be an offensive scent, and generally folks with cacosmia may even understand a pleasing odour (for everybody else) as foul-smelling.
As a part of taking a scientific historical past of the olfactory dysfunction, the clinician will ask about a number of components which can assist decide the potential underlying purpose. The timing of onset (sudden or gradual), was there a precipitating occasion (eg head trauma), any related signs (eg, lack of sense of style) or potential environmental exposures/cigarette smoking/remedy/radiation side-effects.
If in your case, a reversible trigger is discovered (eg, nasal polyps, dental caries, dry mouth or continual nasal congestion) and absolutely handled, then the prospect of constructing an entire restoration is superb.
As nasal/paranasal sinus illnesses are the commonest causes of olfactory dysfunction, it is likely to be a good suggestion to attend one other ENT surgeon for one more thorough examination of the nasal cavity and paranasal sinuses (it has been seven years because you had been final examined).
Standardised olfactory (scent) exams could be carried out in specialist centres and could also be useful in figuring out the diploma of olfactory dysfunction. Typically odourants similar to chocolate, turpentine, espresso, moth balls, or cleaning soap are used.
On uncommon events, when scientific historical past or sure indicators/different signs are current, a clinician might take into account scans similar to an MRI mind. The explanation why imaging is never performed is as a result of the overwhelming majority of scans come again regular. For instance, in a latest examine of 839 sufferers, lower than 1pc of sufferers had been discovered to have an imaging abnormality that defined their olfactory dysfunction.
