The nasal columella is a subunit anatomical structure of the external nose that connects the nose to the upper lip. A complete and aesthetically pleasing nasal columella structure is also an important component of an aesthetically pleasing nasal profile.
Visually, the nasal columella separates the nostrils on either side and is located in the middle of the nostrils on both sides. It is positioned at the top of the human middle above the upper lip, then perpendicular to the plane of the upper lip and extends upward to connect with the nasal head area. Generally speaking, from the nose to the upper lip, the nasal column is thin in the middle and slightly wider at the ends.
If you try to touch the nasal columella with your hand, you can find that the surface of the nasal columella is thick skin, which has no different texture from other parts of the nose. If you touch it deeper, you can feel that there is cartilage inside the nasal column as well. It is the presence of cartilage in the nasal column that allows the nasal column to stand up in a relatively well-defined position. The cartilage inside the nasal column is formed by the cartilage on both sides of the nose converging at the nasal tip and extending backward.
If you touch the nostrils again with your finger near the nasal column, you can find a large upright piece of cartilage that is not connected to it, which is the nasal septum cartilage.
The nasal column also has a unique aesthetic role in the nose. Too short or too long nasal column is not an aesthetic appearance of the nose, likewise the angle between nasal column and upper lip is also an important aesthetic feature with its unique angle, generally the angle between nasal column and upper lip is 90°-95° is the most suitable nasal-upper lip angle.
