In Brief The key to achieving an excellent result following rhinoplasty lies in a strong fundamental knowledge of nasal anatomy. purpose this study was analyze the anatomic and histologic relationship nose alar-facial crease. Fifteen cadaver noses were dissected total thirty lower lateral cartilages measured. Two fresh fixed neutral buffer formalin embedded paraffin. They then sectioned into 6-μ coronal sagittal sections stained with hematoxylin eosin, Eosin von Geison, safranin evaluate for collagen, elastin muscle, respectively. Measurements showed average crural height 23.5 mm (± 2.5 mm), crus width 11.7 1.5 domal 5.7 0.9 intercrural distance 20.2 3.2 mm). No statistical differences noted between male female measurements. Histologic area crease have greater quantity fibers compared or cartilage. These predominantly orientated vertically (anterior-posterior) rather than horizontally (cephalo-caudad). This demonstrates higher ratio collagen region A demonstrated no cartilage dimensions women men. Histologically high predominance fibers.
