The inferior concha, also known as the inferior nasal concha or the turbinate bone, is a small, curved bone located in the nasal cavity of the human skull. It is one of three conchae in the nasal cavity, with the other two being the middle and superior conchae. The inferior concha plays an important role in the respiratory system, helping to filter, humidify, and warm the air we breathe.
The inferior concha is a thin, scroll-shaped bone that is situated between the lateral wall of the nasal cavity and the upper part of the nasal septum. It is covered by a thin layer of mucous membrane, which helps to moisten and warm the air as it passes through the nasal cavity. The inferior concha is also lined with cilia, tiny hair-like structures that help to move mucus and trapped particles out of the nasal cavity and towards the pharynx.
In addition to its respiratory functions, the inferior concha also plays a role in the sense of smell. The olfactory neurons, which are responsible for detecting odors, are located in the mucous membrane lining the inferior concha. When we breathe in an odor, the olfactory neurons in the inferior concha send signals to the brain, allowing us to perceive the scent.
While the inferior concha is an important structure in the nasal cavity, it can sometimes cause problems if it becomes swollen or inflamed. This can lead to a condition known as inferior concha hypertrophy, which can cause difficulty breathing and a feeling of congestion in the nose. In some cases, surgery may be necessary to reduce the size of the inferior concha in order to alleviate these symptoms.
Overall, the inferior concha is a vital structure in the human respiratory system, helping to filter, humidify, and warm the air we breathe. It also plays a role in our sense of smell, allowing us to perceive the many different scents that we encounter in our daily lives.

The three surgical methods include crushing, resection, and turbinoplasty. This is an open access article distributed under the terms of the Creative Commons Attribution License CC-BY 4. Where is inferior turbinate located? They increase the surface area of these cavities, thus providing for rapid warming and humidification of air as it passes to the lungs. Do humans have nasal turbinates? It sits on the vertical bony plate known as the nasal septum, separating the nasal cavity into two bilateral and symmetrical anatomical caves. In addition, immediately before it traverses the greater palatine canal, it gives off branches that supply the mucous membrane of the inferior nasal concha and the inferior and middle nasal meatuses. Because the nasal cavity is symmetrical, there are technically pairs of turbinates, leading to 6 in total for an average human. Data were collected on age, gender, presenting symptoms, physical examination findings, associated findings in the CT scan, type of intervention, surgical technique used, and the presence of complications related to the procedure.
What does the inferior nasal concha do?
What is nasal concha? This piece extends horizontally along the lateral walls of the Nasal Cavity, articulating with the medial wall of the Maxillae and with the Palatines. Unlike the inferior conchae, these are not separate bones, but medial extensions of the labyrinth portion of the ethmoid bone. In contrast, if the patient is symptomatic, the management strategies could vary from medical to surgical interventions. Seven articles were excluded because they were missing significant information regarding inclusion criteria, and five were excluded either because they were non-English language publications or they lacked an abstract. Nasal concha, also called Turbinate, or Turbinal, any of several thin, scroll-shaped bony elements forming the upper chambers of the nasal cavities. How many Concha are there? Medial surface It is a convex surface full of small perforations for apertures and marked with longitudinal grooves for accommodating several blood vessels.
Nasal Concha Explained
This is also known as pneumatization of the turbinate. They do this by swelling up with increased blood flow. A turbinate becomes enlarged when the mucosa gets inflamed due to rhinitis or chronic sinusitis. The conchae project medially into the nasal cavity forming four air channels through which inhaled air can flow and increasing the surface area between the lateral wall and the passing air. The inferior border is free, thick, and cellular in structure, more especially in the middle of the bone. Functionally, the most important turbinates are the inferior, or lower, turbinates.

This technique showed a significant reduction in the CB size upon measuring the presurgical and one-year postsurgical endoscopic nasal cavity images and CT scans of all the patients who were included in the study In 1988, Zinreich et al. The middle meatus is longer and deeper than its superior counterpart. What is the function of the nasal Meatuses formed by the nasal Conchae quizlet? They regulate airflow and warm and humidify the air you inhale. Lymphatic drainage for nasal conchae For lymphatic drainage, lymph from the nasal conchae drains into the submandibular, deep cervical, and retropharyngeal nodes. A retrospective study conducted in Japan between 2000 and 2004 on 2,500 cases with coronal paranasal sinus CT has revealed 10 patients with PITs, with an incidence of one in 250 patients 6 females and 4 males and with an average age of 29. The mean age of the patients was 27 years old, and the majority were females, comprising 69.
