    Background: In a previous study, our group demonstrated that cultured autologous fibroblast-seeded artificial dermis was superior to artificial dermis for covering defects after surgical excision of basal cell carcinoma (BCC) in terms of scar quality. However, utilizing cultured cells for clinical purposes requires Food and Drug Administration–approved facilities and techniques and a lengthy culture period. The purpose of this retrospective study was to compare the effects of tissue-engineered dermis containing stromal vascular fraction (SVF) cells with artificial dermis on scar quality after surgical excision of BCC on the nose. Methods: Between April 2010 and February 2018, patients who were treated with tissue-engineered or artificial dermis grafts and those with a follow-up period of greater than a year were included in this study. The Patient and Observer Scar Assessment Scales (POSAS) were compared between two groups according to the location of the graft, which was classified based on nasal subunits: the upper two-thirds zone; the lower one-third zone, except for the ala; and the alar zone. Results: A tissue-engineered dermis composed of SVF cells and an artificial dermis were applied to 30 and 47 patients, respectively. In upper two-thirds and lower one-third zones, except for the ala, no statistically significant differences were found in any parameters. In the alar zone, statistically significant differences were detected in 10 of 21 POSAS parameters. Conclusion: To cover nasal defects, the tissue-engineered dermis graft may be superior to the artificial dermis graft regarding scar quality at the ala. However, there were no significant differences in other zones.
