Accuracy of Predissection Assessment of the Lower Lateral Cartilage Configuration: A Cadaveric Study

Abstract

The configuration of the lateral crus of LLC cannot be accurately assessed prior to exposure of the cartilage. A rhinoplastic surgeon who embarks on nasal tip surgery should be familiar with a number of techniques to address any tip deformity encountered after exposure, as the preoperative clinical and photographic assessments cannot reliably demonstrate the type of LLC deformity.

Lateral Crural Transposition Flap in Tip Correction

“…Preoperative assessments were confirmed with intraoperative findings because the configuration of the lateral crus of LLC cannot be accurately assessed before exposure of the cartilage and the preoperative clinical and photographic assessments cannot reliably demonstrate the type of LLC deformity. 10 Deformities like external valve dysfunction, concavity, convexity, and mixed patterns were recorded. Six-month postoperatively, the operated noses were examined for deformities like external valve collapse, pinched tips, tip asymmetries, or alar notching.…”

Which Approach Should Be Applied in Rhinoplasty: Open or Endonasal?

“…Since the procedure necessitates precise siting of the incision on the caudal margin of the lower lateral cartilage, being well-acquainted with nasal anatomy is a prerequisite. In practical terms, there is no absolutely definite way to define where the margin of the cartilage will be situated, even though the anatomy of the lower lateral cartilages [8][9][10][11][12][13][14][15][16][17][18] and the alar lobule [19] has been investigated in a number of studies. As a result, the operation must proceed stepwise, with dissection uncovering the margin of the cartilage.…”
