Abstract

The aim of this study is to elucidate the cutaneous distribution of the zygomaticofacial nerve (ZFN). Twenty hemifaces of 10 adult Korean cadavers were dissected. ZFN-innervated limits were rectangular and each side was 18.8 +/- 4 mm and 15.8 +/- 3.4 mm. The center of the rectangle was located laterally at 17.3 +/- 5.5 mm from the lateral canthus and then inferiorly at 18.1 +/- 3.1 mm. The cutaneous area innervated by the ZFN was rectangular shaped having a horizontal side that was 9.3 +/- 4% to 27.3 +/- 7.5%of the line from the lateral canthus to the root of helix and a vertical side that was 13.9 +/- 5.8% to 35.7 +/- 5.4% of the line from the lateral canthus to the oral commissure level. Knowledge of ZFN innervation is available with an intraoral approach in maloplasty or midface lift.
