Exploring Nasal Wall Cartilage Asymmetry in Rhinoplasty: Implications for Postoperative Symmetry.

Facial symmetry is prized for its association with health, genetic quality, and attractiveness, but minor asymmetries are common. Human asymmetry tends to favor the left side and is noticeable in various nose parts. However, the discrepancy in cartilage thickness between the nose's right and left sides remains understudied. This cross-sectional study involved 60 patients undergoing primary open rhinoplasty. During routine rhinoplasty Procedure, upper and lower lateral cartilage strips were excised from each patient, yielding four tissue samples. Tissue thickness and width were measured using a microscope stage calibration slide. This approach systematically assessed left and right cartilage thickness differences in primary open rhinoplasty patients, offering insights into nasal asymmetry and potential surgical implications. Out of 60 patients, 43 were female (72%) and 17 were male (28%). The mean thickness of upper lateral (UL) cartilage was 0.53 mm on the right and 0.54 mm on the left side (P value= 0.52). For lower lateral (LL) cartilage, the mean thickness was 0.50 mm on the right and 0.54 mm on the left side (P value < 0.001), indicating significant left-sided dominance. This dominance was consistent across both sexes. Our study highlights the significance of addressing subtle nasal cartilage asymmetries to improve postoperative symmetry. Modifying nasal cartilage microstructures during rhinoplasty can enhance both aesthetic and functional outcomes. This journal requires that authors assign a level of evidence to each article.
