Notes

The supreme nasal concha (Concha nasalis suprema) is a small, bony structure located in the nasal cavity. It is one of the nasal conchae, which are curved bony plates that project from the lateral walls of the nasal cavity. The supreme nasal concha is situated above the superior nasal concha and is the smallest and most superior of the nasal conchae.

Anatomy

The supreme nasal concha is part of the ethmoid bone, which is a complex structure that contributes to the medial wall of the orbit, the roof of the nasal cavity, and the nasal septum. The ethmoid bone consists of several parts, including the cribriform plate, the perpendicular plate, and the ethmoidal labyrinth.

Function

The primary function of the supreme nasal concha, like the other nasal conchae, is to increase the surface area of the nasal cavity. This helps to warm, humidify, and filter the air that is inhaled through the nose. The conchae also play a role in directing airflow within the nasal cavity, which can affect the sense of smell.

Clinical significance

The supreme nasal concha is not always present in every individual, and its size and shape can vary. It is less commonly discussed in clinical settings compared to the inferior nasal concha, middle nasal concha, and superior nasal concha. However, variations in the anatomy of the nasal conchae can contribute to conditions such as nasal obstruction and sinusitis.
