Nasal Anatomy

[hikut]

Your sense of smell, the nose and it's components, or rather the olfactory organ, is a very complex process of changing scents into neurotransmissions that your brain then processes to determine was is sweet, sour, noxious, spoiled, etc. The process begins by inhaling an odor which is then carried into a network of passages and is transmitted and sorted out by the rhinencephalon:

rhin*en*ceph*a*lon
plural - la
(noun)
: the anterior inferior part of the forebrain that is chiefly concerned with olfaction and that is considered to include the olfactory bulb together with the forebrain olfactory structures receiving fibers directly from it and often esp. formerly the limbic system which is now known to be concerned with emotional states and affect --called also smell brain (Merriam-Webster Medical Dictionary)

Of course there is no real need for the sense of smell but there are certain needs for maintaining balance in temperature and moisture although even this is not necessary for life sustenance. The turbinate structures are responsible for maintaining this harmony and without this it sometimes reported that disorientation, headaches and musosal dryness can ensue when the turbinate structure is not in proper order.

All in all, I do realize that you are more than likely concerned with appearance rather than function although, with secondary and tertiary rhinoplasty loss or hindrance of function is unfortunately a reality for many. From difficulty breathing to headaches, from post-surgical nasal drip to depression - there is more to rhinoplasty than aesthetics.
