Lateral crus pull-up: a method for collapse of the external nasal valve

Area of Science:

• Rhinology
• Plastic Surgery
• Otolaryngology

Background:

• Nasal vestibule collapse during breathing is a common issue.
• Weak or medially displaced lower lateral cartilages often cause this.
• Existing treatments frequently require external rhinoplasty or extra incisions.

Purpose of the Study:

• To describe an innovative endonasal surgical technique.
• To address nasal valve collapse by widening and strengthening the lateral nasal structures.

Main Methods:

• A permanent submucosal spanning suture is placed.
• The suture connects the piriform aperture to the distal lower lateral cartilage.
• This is an endonasal approach, avoiding external incisions.

Main Results:

• The technique achieves superolateral rotation of the lateral crura.
• This rotation increases the cross-sectional area of the nasal airway.
• The spanning suture provides enhanced support to the nasal vestibule's lateral wall.

Conclusions:

• This endonasal suture technique offers an elegant solution for nasal valve collapse.
• It effectively widens the nasal airway and supports the lateral nasal wall.
• The method avoids the need for external rhinoplasty approaches.
