Columellar-labial angle (nasolabial angle)

The angle formed between the columella and the lip. This angle is really important for profile management. Rhinoplasty surgeons have to know the exact angles.

The columellar-labial angle, also called the nasolabial angle, is the angle formed where the columella meets the upper lip when the face is viewed from the side. It is an important part of profile analysis because it reflects the rotation and position of the nasal tip. A more acute angle can make the tip look droopy or the nose appear longer, while a more open angle may make the tip look overly rotated or the nose appear shorter.

There is no single ideal angle for every patient. The appropriate range depends on facial structure, sex, ethnicity, upper-lip shape, chin projection, and the patient’s goals. The angle is also influenced by the caudal septum, medial crura, anterior nasal spine, and the support holding the tip in position. For that reason, changing the angle requires more than simply lifting or lowering the tip.
