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.
A CT scan showing evidence of the nasal cycle: the more patent airway is on the right of the image, the swollen turbinates congesting the left. The nasal cycle is the subconscious [1] [2] alternating partial congestion and decongestion of the nasal cavities in humans and other animals.
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.
ENS is a potential complication of nasal turbinate surgery or injury. [1] [2] Patients have usually undergone a turbinectomy (removal or reduction of structures inside the nose called turbinates) or other surgical procedures that injure the nasal turbinates. ENS patients may experience a range of symptoms.
A turbinectomy is usually performed to resolve turbinate hypertrophy, where the turbinates are swollen and enlarged. Common causes of this condition are allergies, environmental irritants, or a deviated septum. [medical citation needed]
Adenoid hypertrophy, also known as enlarged adenoids refers to an enlargement of the adenoid (pharyngeal tonsil) that is linked to nasopharyngeal mechanical blockage and/or chronic inflammation. [1] Adenoid hypertrophy is a characterized by hearing loss , recurrent otitis media , mucopurulent rhinorrhea , chronic mouth breathing , nasal airway ...
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]
