Concave lateral crura

When the lateral crura bow into the nasal cavity. This can cause breathing and cosmetic issues. Sometimes, this is a result of previous rhinoplasty.

The lateral crura are the outer portions of the lower lateral cartilages that help shape and support the nasal tip and nostril sidewalls. Concave lateral crura occur when these cartilages curve inward toward the nasal cavity instead of maintaining a smooth outward contour. This can create a pinched or uneven appearance around the tip and nostrils, and it may also narrow the external nasal valve where air enters the nose.

Some patients are born with this cartilage shape, while others develop it after trauma or previous rhinoplasty. When too much cartilage has been removed or weakened during an earlier procedure, the sidewall may lose support and pull inward during breathing. A surgeon evaluates the nose from the front, base, and side views and may also watch how the nostrils behave during a deep breath. This helps determine whether the concern is mainly cosmetic, functional, or a combination of both.

Treatment depends on the strength, position, and amount of remaining cartilage. Options may include reshaping and repositioning the lateral crura, using sutures to improve contour, or adding a lateral crural strut or batten graft for support. The goal is to create a smoother tip and nostril shape while keeping the airway open and avoiding an overbuilt appearance.

For patients considering rhinoplasty or revision rhinoplasty in Beverly Hills, understanding concave lateral crura can help explain why the lower part of the nose may look pinched or feel restricted. Dr. Richard Zoumalan carefully evaluates the nasal tip, sidewalls, and airway to determine whether cartilage repositioning or grafting may improve both appearance and breathing.
