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

Area of Science:

• Plastic Surgery
• Facial Anatomy
• Rhinology

Background:

• Facial symmetry is linked to health and attractiveness.
• Minor facial asymmetries are common, particularly in the nose.
• Nasal cartilage thickness asymmetry is understudied.

Purpose of the Study:

• To investigate differences in nasal cartilage thickness between the right and left sides.
• To assess the clinical implications of nasal cartilage asymmetry in rhinoplasty.

Main Methods:

• Cross-sectional study of 60 patients undergoing primary open rhinoplasty.
• Excised upper and lower lateral cartilage samples were measured for thickness.
• Microscopic analysis systematically assessed left vs. right cartilage thickness.

Main Results:

• No significant difference in upper lateral cartilage thickness (P=0.52).
• Significant left-sided dominance in lower lateral cartilage thickness (P < 0.001).
• Left-sided dominance was consistent across both male and female patients.

Conclusions:

• Subtle nasal cartilage asymmetries, especially in lower lateral cartilage, are prevalent.
• Addressing these microstructural differences during rhinoplasty can enhance outcomes.
• Consideration of cartilage thickness asymmetry is crucial for improving postoperative symmetry.
