We are here explain about the Classification of Turbine. Most people know about the septum and sinuses when it comes to breathing. But not many people (even most doctors) know about the nasal turbine. Turbine are like wings along the sidewalls of your nasal cavity, opposite your midline nasal septum. There are three paired structures: the inferior, middle and superior turbine. Your sinus passageways drain from underneath the middle turbine. Swollen turbine are probably responsible for most cases of nasal congestion.
What is turbine?
The turbine are bony on the inside and surrounded by mucous membrane covering, with very rich vascular tissue in between. The vascular tissue can engorge significantly, like what occurs with the penis. Any degree of inflammation, irritation or infection can aggravate turbinate swelling. Allergies are a common cause. Even weather changes such as temperature, pressure or humidity fluctuations can aggravate turbinate swelling. In many instances patients are told by their medical doctors that they have nasal polyps. When in fact, it’s a very enlarge turbinate that’s see. Sometimes it’s difficult to tell whether a swollen structure is a turbinate or a polyp. A polyp is a protuberance of mucous membrane that grows beyond the normal tissue boundaries. Most nasal polyps originate from underneath the middle turbine where the sinuses drain. But polyps can also occur anywhere in the nose, including on the Classification of Turbine.
One important feature of the turbine that not too many people know about is what’s call the nasal cycle. The turbine alternate in size from side to side every few hours. One side shrinks and the other side swells. Normally you won’t notice this, unless both your turbine are somewhat congested. If you have a deviated septum, then you’ll notice this more. Gravity also affects the size of your nasal turbine. When you lay down, blood pools in the vessels, leading to slight engorgement. However, your involuntary nervous system detects this relative change and automatically constricts your blood vessels to improve breathing. The same process occurs when you exercise-due to activation of sympathetic nervous system, turbine shrink, opening up your breathing passageways.
Sometimes, the balance between the two halves of involuntary nervous system(the sympathetic and parasympathetic parts) is out of alignment. And this automatic mechanism doesn’t work properly. So when you lay down or exercise, the vessels don’t constrict fully. Other times, the turbine become extra sensitive to allergies, weather changes, chemicals, scents or odors. Once it’s irritate, an inflammatory reaction occurs which leads to engorgement and production of mucous. This is call vasomotor or non-allergic rhinitis. Throat acid reflux has been shown to associate with this condition.
Ultimately, how well you breathe through your nose is determine by a combination of the size of your turbine. Your septal geometry, and the how flimsy your nostrils are. (See the other sections on the septum and flimsy nostrils.) Your nose is not just a passive tube that acts a channel for air to pass into the lungs. It’s a very dynamic structure, able to change minute by minute.
