Illustration of upper respiratory system. In anatomy, a nasal concha (/ ˈ k ɒ n k ə /; pl.: conchae; / ˈ k ɒ n k iː /; Latin for 'shell'), also called a nasal turbinate or turbinal, [1] [2] is a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans and various other animals.
According to Heetderks, the cycle is the result of alternating congestion and decongestion of the nasal conchae or turbinates, predominantly the inferior turbinates, which are by far the largest of the turbinates in each nasal fossa. Turbinates consist of bony projections covered by erectile tissue, much like the tissues of the penis and clitoris.
Large, swollen inferior turbinates may lead to blockage of nasal breathing. Allergies, exposure to environmental irritants, or a persistent inflammation within the sinuses can lead to turbinate swelling. Deformity of the nasal septum can also result in enlarged turbinates. Treatment of the underlying allergy or irritant may reduce turbinate ...
Bullosa refers to the air-filled cavity within the turbinate. [1] It is a normal anatomic variant seen in up to half the population. Occasionally, a large concha bullosa may cause it to bulge sufficiently to obstruct the opening of an adjacent sinus, possibly leading to sleeping apnea or breathing disorder related to areas innervated by the ...
The human nose is the first organ of the respiratory system.It is also the principal organ in the olfactory system.The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two.
Before and after surgical restoration of the lateral wall (arrow in right-side image) to simulate the function of the missing inferior turbinate. A 2015 meta-analysis identified 128 people treated with surgery from eight studies that were useful to pool, with an age range of 18 to 64, most of whom had been experiencing ENS symptoms for many years.
Chronic atrophic rhinitis, or simply atrophic rhinitis, is a chronic inflammation of the nose characterised by atrophy of nasal mucosa, including the glands, turbinate bones and the nerve elements supplying the nose. Chronic atrophic rhinitis may be primary and secondary.
The ethmoid sinuses or ethmoid air cells of the ethmoid bone are one of the four paired paranasal sinuses. [1] Unlike the other three pairs of paranasal sinuses which consist of one or two large cavities, the ethmoidal sinuses entail a number of small air-filled cavities ("air cells"). [2]
