Artificial Dermis Graft Following Basal Cell Carcinoma Removal on the Nose: A Comparison of Scar Contracture Across Nasal Subunits

초록

Background: This study aimed to compare the degree of scar contracture following artificial dermis grafting after excision of basal cell carcinoma on the nose categorized by defect location into three nasal subunits. Methods: Anthropometric analysis was conducted on seven parameters using patients' photographs to compare changes between preoperative and postoperative measurements based on nasal subunits. Defect locations were classified as: (1) dorsum and sidewalls (D zone), (2) tip (T zone), and (3) alar lobule (A zone). Results: The greatest change in alar height asymmetry was observed in zone A. Changes in nasal tip projection ratio and nasofrontal angle were the most significant in zone T. No other measurements showed statistically significant differences among the three zones. Conclusions: Careful consideration is recommended when applying artificial dermis grafting in zones A and T. Conversely, zone D appears to be the most suitable for artificial dermis grafting. © 2024 Wiley Periodicals LLC.
