Anatomical Study of the Lateral Crural Strut Graft in Rhinoplasty and Its Clinical Application

Abstract

Lateral crural strut graft improves external nasal valve and increases nasal tip projection and basilar nasal width.

Effectiveness of using a bioabsorbable implant (Latera) to treat nasal valve collapse in patients with nasal obstruction: systemic review and meta‐analysis

“…Methods dealing with LWI include enhancing the strength of side walls through improving the cross‐sectional area of the nasal airway, strengthening the lateral nasal walls to resist breathing forces, or a combination of both techniques 7 . Grafting procedures such as using a spreader graft, butterfly graft, splay graft, alar batten graft, lateral crural strut graft, or alar rim graft, alongside suture techniques such as the suspension suture, flaring suture, and horizontal mattress bending suture have been developed and used for LWI treatment 8‐19 . These techniques have produced satisfactory results; however, most of them require external or endonasal rhinoplastic approaches 20 .…”

The miniature lateral crural strut graft: Efficacy of a novel technique in tip plasty

“…Other proposed sources of the LCSG include conchal cartilage, rib cartilage, and cephalic LC . The original description and the supporting cadaver studies used an average of a 20‐ to 30‐mm length and a width of 4 to 10 mm, which adds burden to the cartilage available for grafting . On the contrary, this is not the case in the newly described mini‐LCSG, where a 10 to 14 mm × 3 to 4 mm mini‐LCSG is used along the cephalic half of the LC to reshape and straighten the LC as well as define the dome medially.…”

Management of Lateral Wall Insufficiency

“…The pocket can be extended laterally to the piriform aperture, alar base, or rim, depending on the patient's anatomic needs. 34 The LCSG is placed on the deep surface of the lateral crus, with the medial apex of the graft just lateral to the dome and cephalic margin not exceeding past the cephalic edge of the native lateral crus. The graft is secured with 2 to 3 sutures to the lateral crus with the knot placed away from the vestibular skin.…”
