Answer:
Lateral crural strut grafts are strips of autogenous cartilage that are sutured to the deep surface of the lateral crura, enabling the correction of lateral crural deformities and deficiencies. The lateral crural strut graft is useful in boxy nasal tip correction. Transdomal sutures create more angulation in the dome but may have a tendency to displace medially the lateral crus with resultant airway compromise. Lateral crural strut grafts are useful in correcting this potential problem. The malpositioned lateral crura that has a cephalad orientation may be corrected by a lateral crural strut graft either alone or in conjunction with alar cartilage repositioning. Alar rim collapse from overzealous resection can be strengthened by lateral crural strut graft. The concave lateral crura are cosmetically displeasing and may cause incompetence of the external nasal valve requiring lateral crural strut grafts to add stability to the nostril rim.
