Research has shown that there is a strong connection between these nerve endings and activation of the olfactory receptors, but science has yet to fully explain this interaction. Clinical significance
Dysfunction
Large, swollen conchae, often referred to clinically as 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 swelling. In cases that do not resolve, or for treatment of deviated septum, turbinate surgery may be required. Surgery
Turbinectomy is a surgery for the reduction or removal of the turbinates. There are different techniques, including bipolar radiofrequency ablation, also known as somnoplasty;  reduction by the use of pure heat;  and turbinate sectioning. In the case of sectioning, only small amounts of turbinate tissue are removed because the turbinates are essential for respiration. Risks of reduction of the inferior or middle turbinates include empty nose syndrome. Dr. Houser: "this is especially true in cases of anterior inferior turbinate (IT) resection because of its important role in the internal nasal valve. "Concha bullosa is an abnormal pneumatization of the middle turbinate, which may interfere with normal ventilation of the sinus ostia and can result in recurrent sinusitis. Other animals
Generally, in animals, nasal conchae are convoluted structures of thin bone or cartilage located in the nasal cavity. These are lined with mucous membranes that can perform two functions.
They are enriched with airflow pressure and temperature-sensing nerve receptors (linked to the trigeminal nerve route, the fifth cranial nerve), allowing for tremendous erectile capabilities of nasal congestion and decongestion, in response to the weather conditions and changing needs of the body. In addition, the erectile tissue undergoes an often unnoticed cycle of partial congestion and decongestion called the nasal cycle. The flow of blood to the nasal mucosa in particular the venous plexus of the conchae is regulated by the pterygopalatine ganglion and heats or cools the air in the nose. The nasopulmonary and nasothoracic reflexes regulate the mechanism of breathing through deepening of inhalation. Triggered by the flow of the air, the pressure of the air in the nose, and the quality of the air, impulses from the nasal mucosa are transmitted by the trigeminal nerve to the breathing centres in the brainstem, and the generated response is transmitted to the bronchi, the intercostal muscles, and the diaphragm. The conchae are also responsible for filtration, heating, and humidification of air inhaled through the nose. Of these three, filtration is achieved mostly by other more effective means such as mucous and cilia. As air passes over the conchae, it is heated to 32–34 °C (89–93 °F), humidified (up to 98% water saturation) and filtered. Immunological role
The respiratory epithelium that covers the erectile tissue (or lamina propria) of the conchae plays a major role in the bodys first line of immunological defense. The respiratory epithelium is partially composed of mucus-producing goblet cells.
