What Is Alar Collapse

Alar collapse and contraction of the nasal tip fol- lowing. rhinoplasty are the direct result of a weak- ness in the lateral segments of the lower lateral cartilages. This weakness is caused by overresection of the lateral crura when the surgeon attempts maximal tip reduction (Figure 1).

What causes nasal valve collapse?

Nasal valve collapse usually occurs due to weakness or injury to the nose. This could be a traumatic injury or previous nose surgery. Additional reasons that this problem may develop include: Scar tissue.

What is the Alar?

The alar crease (alar facial groove) is the junction between the nose and cheek and is an important landmark to be preserved in rhinoplasty surgery. A cephalically positioned alar facial junction will lead to a snarled appearance to the nose, while a caudally positioned alar facial junction can lead to alar hooding.
